Do not exceed the rated limits of the power unit or use the power unit for applications beyond its design capacity. There are a number of issues that could cause this condition. If required, overhaul or replace motor. Vrifier la connexion du fil tanche une totale efficacit. Garder suffisamment dhuile dans le rservoir. 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. 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. 3.Normally suggestion the oil with ISO viscosity grades 32 and 46 (at 20-30). Read the operation instruction before installing valve. Check to ensure the pump to motor coupling is undamaged. 0000001742 00000 n
2.Target will not take responsibility for wrong installation and wrong application. It Have to be closed for power up.If Solenoid Valves without manual override then clean this solenoid valve in manifold block part. La batterie doit tre pleinement charge en tout temps. Turn to the access state, then with the gravity weight pressure, the oil will return to the T port (back to oil tank) through solenoid valve and needle valve (throttle). To help, weve put together a list of things you should check before you tear into your pump. The hydraulic circuit control valve must be in the OFF position when coupling or uncoupling the hydraulic hoses. 0000007355 00000 n
Check that the relief valve is adjusted properly for the pump specifications and the application. Quand lunit de puissance ne dcent pas: Suggestions: Vrifier le bouchon de dcente sur la valve du solnode, ouvrir dans le sens de lhorloge. 5.Do not touch the motor and hydraulic parts directly. Seized bearings, or pump shafts and other internal damage may prevent the pump from operating all together. 0000010193 00000 n
When press the down button of the button remote or wireless remote, the motor will be shuttle down, and the solenoid valve will 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. Check to ensure that your pump drive motor is turning over and is developing the required speed and torque. A sheared pump coupling is an obvious cause of failure, however the location of some pumps within hydraulic systems makes this difficult to check so it may go overlooked. 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. What applications do your hydraulic power units have? Ask and get your hydraulic power units price now! Keep sufficient oil in oil tank in if not use for long time, please start device once per week. So that you can keep your system up and running and avoid unplanned downtime. Clogged or dirty fluid filters. 0000005515 00000 n
The motor can work but the system cant supply oil: Suggestion: 5. Wear gloves to protect your hand and wear goggles to protect your eyes. Clogged inlet lines or hoses. 2.The relief valve was set to a certain pressure (160 bar, 180 bar, 210 bar 3200 PSI relief valve, etc. 0000020734 00000 n

Solenoid valve was blocked, please clean the solenoid valve and clean the oil. Use torque wrench to tighten valve cartridge. Change the oil after first 100 working hours. Viscosity of the oil is too high, please use suitable viscosity oil. Grease or motor oil could cause valve failure when the hydraulic fluid mixes with foreign substance and gum up valves. trailer
