Needle should jump when contact is made. No movement means an open capacitor. No resistance mean capacitor is shorted. Motor wired incorrectly Check wiring diagram Reconnect for proper voltage as per wiring diagram Inadequate ventilation Check air temperature where pump is located. If over degrees Fahrenheit, overload my be tripping on external heat.

Provide adequate ventilation or relocate pump. Prolonged low pressure delivery. Prolonged operation at very low pressure places heavy overload on pump.A waterjet pressurizes water and creates a high velocity stream of water, called a jetstream that erodes material. Waterjet machine tools use high-pressure pumps to force water through a tiny orifice inside a nozzle, creating a narrow, high velocity jetstream.

In the case of abrasive waterjets, fine abrasive particles typically garnet are pulled into the jetstream within the nozzle. A computerized motion control system moves the nozzle and the jetstream from the nozzle erodes a thin line from the material.

Pure waterjets without abrasive are generally used to cut soft materials like food and foam, while abrasive waterjets are used to cut hard materials like steel. Abrasive waterjets can cut virtually any material, metal and nonmetal, from carbon fiber to copper, glass to granite, titanium to tungsten and practically anything in between.

Waterjet systems can vary, but most are made up of a high-pressure pump, a cutting table that holds the work material, a nozzle that emits the jetstream, an X-Y motion system to move the nozzle and a PC-based controller. OMAX tables are water-filled tanks with slats that hold the material.

The material can be submerged under the water, making the cutting quiet and clean. OMAX waterjets have hoppers that hold and dispense abrasive during the cutting process. Most of the maintenance on an abrasive waterjet involves servicing the pump and the cutting head. The exact type and frequency of maintenance will depend on how the machine is used pump pressure, type of material cut, etc.

The nozzle needs to be changed out fairly frequently to ensure precision cutting. Changing out a nozzle takes just a few minutes. The wear components in the cutting head need to be changed out occasionally. This takes approximately 10 minutes.

Cutting Head Technology

The high pressure pump needs regular servicing. Our direct drive pumps are very easy to service and, depending on the pump model, a rebuild typically takes hours. Accumulated abrasive and work material particles need to be regularly removed from the tank.

This work can be automated by using a Solids Removal System that continually removes sludge without taking the waterjet machine offline, or the sludge can be shoveled out manually, which requires draining the tank.

The table slats should be inspected for wear at least once a month and rotated or replaced when worn. We provide free hands-on training including waterjet maintenance for our customers. We also provide online videos and manuals with step-by-step maintenance instructions for our pumps, cutting heads and accessories. OMAX incorporates an advanced cutting model into the controller which automatically creates the optimal cutting path.

It varies speeds and accelerations so that no time is wasted going more slowly than necessary. In addition, the OMAX controller automatically takes advantages of many speed-up tricks that would be too difficult and cumbersome for a human to program. For example:. The OMAX controller automatically adds corner passing on corners that will allow for it.

This process is automatic, and does not require additional work or knowledge from the operator. The OMAX controller automatically adjusts the speeds and accelerations around curves and corners to optimize the tool path for speed, precision, and square corners. This makes it very fast and easy to program the machine, and allows the parts to be machined as quickly as possible while still maintaining the highest tolerances.

The OMAX controller selects the optimal pierce speed, and length, based on an advanced piercing model. This greatly speeds up the otherwise slow process of piercing the material, automatically and optimally.

There are also tools such as the " optimal stack height calculator ", which can be used to greatly speed up some categories of parts.Waterjet High pressure pump trouble shooting. Watrerjet machine has No Pressure. Waterjet intensifier normal shifting. Check inlet water supply to see if enough pressure.

Check if water boost pump optional is working normally. Check if need to replace orifice Id too big or water jet not focused change nozzle. Check weep hole on end bell and end cap of intensifier to see if there is leak of oil or water. If leak water, It is time to replace the HP seal. If leak oil, need to change the LP seal. Check if inlet check valve working properly. If not working, waterjet will return to the low pressure side. Check if outlet check valve is working properly, touch with hand to see if it is hot, if yes, meaning the check valve is leaking on the high pressure side, change inset, or change check valve body.

Check HP plunger. Waterjet intensifier shifting slowly or no shifting. If not shifting and oil pressure is high, remove the wire connection on both sides of the solenoid shifting valve and use a screw driver to push either side to see if the pump can be shifted manually.

If not, check the solenoid valve itself, including the connection of the coil and if the valve is clogged. If yes, then focus on the hall sensor, and the relays that drive the coils of the solenoid valve.

Adjust the position of the Hall sensor switch. Check if the Hall switch and the connected relays. Check oil valve and related electrical circuit including relays. Check if the oil flow rate is too small. If so, adjust to higher flow. Check if the oil Flow rate is too high through hydraulic proportional relief valves. Check if the shifting valve is worn out internal leak too much or clogged.From 2D to multi-axis cutting, Flow technology provides the highest accuracy, fastest cut part. Get a Test Cut.

In standard waterjet cutting, the stream remains perpendicular to the material being cut at all times. The supersonic stream accelerates abrasive particles and erodes the material. It is capable of cutting hard materials such as metals, glass, stone, and composites.

Using standard parameters, this cutting head can cut materials with hardness up to and slightly beyond aluminum oxide ceramic often called alumina, AD You get lower cost of operation since fewer parts are consumed and maintenance intervals are greatly reduced. Additionally, we offer other jewel orifice assemblies, such as ruby and sapphire, which offer good life at a reduced cost.

No expensive carbide mixing chamber exists in this high-tech cutting head. Similar to our orifice assemblies, we have a variety of performance grades of mixing tube available. These nano-grained composite carbide mixing tubes act as the rifle barrel as the abrasive is entrained and accelerated into the powerful cutting stream.

Fragile materials such as these tend to form craters, cracks, or break during high pressure piercing.

UltraPierce is a cutting head option that allows the Paser 4 to pierce these materials easily, saving time and raw material, as well as enhancing the quality of the finished product. UltraPierce's exclusive no clog design pulls abrasive into the cutting head a split second before the waterjet starts so that the waterjet has abrasive particles entrained in the jet stream immediately.

Three independent legs transmit height variations in cutting material in full degree movement on the XY plane. Variations in the XY plane are communicated to the Z-axis producing immediate adjustments in the stand-off height to maintain the ideal cutting environment. It works with both Standard and Dynamic waterjet cutting heads.

The Dynamic Contour Follower can also be used with an optional collision sensor — designed to detect collisions with obstructions and stop the machine before damage can occur.

After all, the pressure is what it is supposed to deliver. So, how do you deal with a pressure washer that loses pressure after just a few seconds of running?

Return it to where you bought it? Call the toll-free number? Simple, you read on and you will be on your way to troubleshoot and remedy your pressure washer even when you are not a mechanic! Water Pressure Issues in pressure washer may also be compared to surging issues.

This happens when you pull the trigger with the water pressure good at the start then weakens after a while. Most likely, this means that the flow rate required by the pressure washer is not met by the water supply.

But, there could be more. Low or no pressure issues for pressure washers are commonly caused by dirty, incorrect, or worn-out nozzles. To see if the nozzle is the culprit, disconnect the nozzle and clean it with a nozzle cleaning kit. This kit is usually provided by the nozzle manufacturer, but if not, some are readily available at DIY stores. Cleaning the nozzles is also making sure they are not clogged. Anything that blocks your nozzle will surely decrease or sometimes increase flow in the systems.

You may use a needle to clear the nozzle tip of any dirt or debris. Nozzles that are eroding or wearing out usually cause gradual pressure loss, as opposed to happening suddenly.

This is because the holes in them that release the water widens over time. As it does, the more water flows through causing the loss of pressure. Aside from making sure that there is water coming to the equipment from the water source, make sure that you replace broken or worn out nozzles. The replacement should be that of which is compatible with the pressure washer you have. Make sure that they are attached tight enough as a partially plugged spray nozzle also causes the pressure washer to lose pressure.

The nozzle should also be in normal PSI position, not below. The unloader relieves the water pressure inside the pump every time spray flow is blocked. Located just above the water inlet, check to see if it is worn out or restricted in some way.

Additionally, the air in the hose causing surging and pulsating, too. Unloader valve has to be one of the most important parts of a pressure washer. If it is not properly maintained, replaced when suspected damaged or broken, it could not just lead to low pressure, but safety hazards and damage to your pressure washer too.

Your water supply must be adequate for the pressure washer. But, if the water supply appears to not cause pressure issues, then you just might have a worn-out pump. Examine and replace them as needed. One of the first things to check, aside from the water source is how it flows. Make sure that the pump is getting enough flow. Therefore, always check the hose for kinks, bends, cuts, or damage. Make sure that your water supply is not restricted by any of these.High-pressure waterjets have advanced substantially over the years in terms of longevity and reliability.

Repair and Troubleshooting Tips for your Water Flosser

Still, they need maintenance and repair from time to time. Problems can be avoided or resolved with simple troubleshooting. High-pressure waterjets are a versatile alternative to cutting methods such as plasma, laser, and mechanical slitting machines. In contrast with thermal cutting, they can precisely cut metal without leaving a heat-affected zone HAZ.

That makes waterjet the preferred method for cutting metal parts for aerospace and construction applications in which metallurgical changes could impact the integrity of the material.

Like other cutting technologies, waterjet systems have changed quite a bit over the past decade. The newest systems can cut faster and more precisely, and they are more reliable for improved uptime. Still, as with any mechanical machinery, problems are sure to surface from time to time. Most of them can be quickly resolved with some simple troubleshooting. The intensifier is probably the hardest-working part of any waterjet system.

Because it has more moving parts, more can go wrong. Some of the most common problems are overstroking, water leaks, and short seal life see Figure 1. Three other common problems with intensifier-based waterjet systems are hydraulic pressure failure, low water pressure, and hydraulic temperature overheating.

It is normal for the intensifier to stroke faster during startup and when changing between low pressure and high pressure; however, during normal operation, the intensifier should stroke smoothly to the left and right at the same speed.

Sometimes, though, the hydraulic piston travels faster in one or both directions, or more than the pump can support. This is called overstroking. It will trigger an alarm. Regardless of whether the overstroking is to the left, right, or in both directions, the first thing you should do is reset the alarm. Sometimes, if the overstroke alarm occurred in error, these steps will reset your system and resolve the problem.

If they do not, then monitoring the intensifier stroke rate will indicate how to proceed. If the intensifier overstrokes in both directionssome steps you can take are:.

Another maintenance area is water leakage. Damage to the high-pressure water seals and the hoops is the most common cause of water leaks from the intensifier. If you see a drip of water every few strokes, it means that the seals are nearing the end of their life and should be replaced within a reasonable period of time.

If you see a drip with every stroke, then you should change your seals at the soonest opportunity. If you see leaks in other areas, that likely indicates a worn part, loose fitting, or damaged seat. It is important to address this leakage right away to prevent further damage to nearby components.Having trouble with your water flosser?

For people who don't like using traditional string floss, a water flosser is a gentle alternative that cleans your teeth using a stream of pressurized water.

It's helped countless people clean their teeth without the discomfort of string floss. But like any appliance, it's also susceptible to accidents, malfunctions, breakage, and leaks. Fortunately, most of these problems are easily resolved and can be fixed at home with minimal tools or experience. Got a problem with your water flosser? Here are some of the most common issues and helpful advice on getting your flosser back up and running.

In general, long-term use with high water pressure and without adequate cleaning can create problems for the device. To keep your flosser running for as long as possible, clean your flosser regularly and make sure that the equipment is properly positioned.

Drain out the water in the reservoir after use--don't leave it standing inside the tank. Taking good care of your device is the best way to eliminate the need for repairs and replacement. Some water flossers can be very noisy and bothersome to those around you, especially if they are sleeping!

Or the Waterpik Ultra which was designed to be quiter than previous Waterpik models. As with any water-related appliance, leakage is always a possible issue. If a part becomes damaged or disengaged, the flosser might leak from the tip, the base, or the reservoir. Blockage can occur after prolonged use, preventing the water in the tank from flowing through the appliance.

If you're experiencing leakage with your Waterpik between the tip and the handle, remove the tip and reinstall it to make sure that it's properly engaged. If the reservoir is leaking, make sure that your device came with a black reservoir valve--if it's missing, you'll need to buy a replacement. Otherwise, make sure the valve is positioned right side-up. Experiencing leaks from the hose? It's likely that the hose is damaged, so you'll need to contact the company for a replacement.

Mold, mineral deposits, and hard water build-up can also become an issue, as deposits frequently build up inside appliances with standing water. When using an appliance that contains standing water, mineral and hard water deposits are always a possible issue, as well as mold growth. Make sure that you regularly clean the appliance with vinegar and warm water to keep your flosser safe and bacteria-free.

You can also clean the reservoir in the top rack of your dishwasher. The tip can be soaked in white vinegar or hydrogen peroxide. Waterpik water flossers normally have a range of pressure settings.

If you are still seeing issues at the highest pressure setting, read on below. If there's no water flow or you're experiencing inadequate pressure, there might be a blockage in the device.

Check the tip and make sure that you clean it regularly. The black reservoir valve can also become clogged, so make sure you clean the valve as well. Inadequate pressure can also result from a misplaced reservoir valve or hard water deposits inside the appliance. Ok, maybe not that messy. First-time users might experience some splashing, which can make a mess on the bathroom counter. This is simply down to improper use of the device and can be easily remedied.

If your flosser is splashing water, try closing your lips around the tip of the flosser and leaning over the sink so that the water drains out of your mouth. It can be a bit difficult to get the hang of it at first, but after a few tries you'll be able to figure it out. In addition to problems with the water flow, the equipment might stop working or malfunction.

Parts can become damaged or broken and require a replacement. The soft tip can become torn or worn out, especially if the device is typically set to high pressure.
