Hydraulic pump not building pressure? 0000002632 00000 n How many types of hydraulic power units do you offer? If this is the case, correct the misalignment and inspect the motor for damage. 2.Hydraulic oil cant be higher than ISO 4404406/14. The best practice is to eliminate the most obvious causes so that you dont end up replacing a perfectly good pump only to find that the issue was something trivial. Our Engineers use 3D and 2D software for hydraulic manifold blocks and hydraulic power unit system design. The hydraulic oil fluid will comes to into hydraulic gear pump through the filter, suction pipe, and then goes into the P port on central manifold ,inside of hydraulic reservoir tanks and delivered to the Outlet port P through check valve and normally closed (NC type) solenoid valve. It is possible that the entire flow could be passing over the relief valve, preventing the pressure from developing. When you press the up button of the Button remote or Wireless remote, the motor will turn on and the gear pump will get on work. To avoid personal injury or equipment damage, all power unit repair, maintenance and service must only be performed by authorized and properly trained personnel. Sometimes incorrect installation leads to mismatched pipe routings between control valves and motors, which can reverse the direction of flow. (, Dinghai Road 66#, Ningbo, Zhejiang, China. Air leak in suctionline. Target Hydraulics is Your Professional Hydraulic Power Units Manufacturer and Supplier in China!

Heres what to check. The Hydraulic Circuit and Wiring Diagram will help you know the function of hydraulic power pack and help you to troubleshooting in your hydraulic systems. So when meet problem, contact ur tech support and dont operate by yourself. Ask and get your hydraulic power units price now! Failure to oil valves will cause O-rings to spin on valve assembly which could cause to O-ring slice length wise, cut or tear. 1.Check the cleanliness of oil before use. 0000001763 00000 n Low oil in the reservoir. At the mean time check valve still stop hydraulic fluid back to the Gear Pump P port. 0000003699 00000 n Distortion could cause valve to not properly open and/or close, which could simulate contamination issues. Hydraulic power units comprise several elements, which may include: pumps, motors, oil tank, pressure filters, return filters, oil level switch, temperature switch, pressure switch, oil cooler/heater, thermostat valve, thermometer, electric terminal box and circuits for circulation/pressure/etc. The needle valve (throttle) is used to control the speed of cylinder down, if the needle valve too tight cylinder down speed will be slow, if the needle valve get loose the speed will get fast. The power unit is not going down: Suggestion: check on valve solenoid, a manual override turn counter clockwise will rise down immediately. What applications do your hydraulic power units have? Accidental engagement of the power unit can cause serious injury. The reservoir is usually the largest item on the unit and can make up part of the framework. Do not inspect or clean the hydraulic pump or hydraulic tool while the hydraulic power source is engaged.

HPUs Applications for a wide range include scissor lifts, electric straddle stackers, tailgate lifts,dump trailers, and so much more. 3.Do not operate the power unit without first reading and understanding the Operating Instructions. Hydraulic oil should be filtered by 10-30um filter. Hydraulic Test is very important in hydraulic power unit trouble shooting. Oil pump must be working with sufficient oil, oil less forbidden. Use Hydraulic fluid to lubricate O-rings, Do Not use any type of grease or motor oil. 0000005515 00000 n But be careful, not lose too much, or the needle valve will leak and cause much noise and danger, the Cylinder will also coming down unstable. 0000001147 00000 n Use torque wrench to tighten valve cartridge. If the solenoid valve does not work, the Cylinder cant drop down. For example, a controlled crown roll HPU would need pumps for: Pump failures will lead to product quality defects and production loss. So that you can keep your system up and running and avoid unplanned downtime. There will typically be one or more backup pumps in order to minimize the risk of a pump failure affecting production. Check to see that the motor is turning the pump in the right direction and if not - look at your piping. which could contribute to poor fluid flow. La batterie doit tre pleinement charge en tout temps. If required, overhaul or replace motor. The solenoid do not work this time, and keep in a check valve state. Target Hydraulics is a manufacturer of hydraulic cartridge valves, hydraulic valve manifold blocks and mini hydraulic power pack units.
