The auto lift power unit，equipped with a 380V/AC/2.2W motor,is widely used in two-post car lift. The reservoir capacity is 1.5 to 3.2 gal in a steel or plastic oil reservoir. The valve is cartridge valve and its system pressure is 2320/2900PSI. All of these make sure that it can flow 1.5 to 2.24 Gal per minute.
After pushing the start button on the motor to lift the car, we can activate the lowering movement by the manual cartridge valve, and control the lowering speed by cartridge flow valve in the return circuit. The power unit is also applied to in different kinds of hydraulic car lift and car scissors lift.
- Due to various types of hydraulic system failure occur more than 80% of the problems are caused by hydraulic oil, so the correct use of hydraulic oil to ensure the system’s reliability is very important.The oil viscosity should be 22-46mm2/s in accordance with ISO3448 viscosity classification.The hydraulic oil should be filtered by a 10-30um filter before put into use.N46 hydraulic oil is recommended.
- Clean all the hydraulic parts concerned before mounting mini hydraulic power pack.Check the oil level in the tank after the initial running of small hydraulic power unit.
- Oil changing is required after the initial 100 operation hours, afterwards once every 3000 hours.We are at your disposal to offer you the power unites with your favorite power,flow,pressure as well as the tank capacity.
- The electric hydraulic pump should be vertical installation.
- The electric hydraulic pump is of s3 duty,which can only work intermittently and repeatedly, i.e., 1 minute on and 9 minutes off.
- To achieve thermal equilibrium of the electric motor, we have to assure that the ratio between interval time and operation time of mini hydraulic power pack is 1:9.
