The characteristics of screw-in cartridge type hydraulic hand pump HPA-6C series have the high-pressure, manual operated, ultra-compact design, easy to carry and replacement, simple operation, and a wide range of applications.The principle of screw-in cartridge type hydraulic hand pump:The oil is absorbed into the cavity when the piston is pulled out through the check valve 1, then the oil flows out by pressing the hand lever through the check valve 2.
How to maintain the screw-in cartridge type hydraulic hand pump:
1.Not exceed the working pressure while operation, not free to adjust the high and low pressure valves.
2.To press the hand lever slowly and firmly, avoid impulse phenomenon in order to extend the service life of the check valve.
3.Lifting the handle while decompression, to prevent depressing too fast .
4.It is not allowed to operate if the oil volume not enough to prevent oil return pressure in the reservoir tube
5.It is allowable while all the connection points are tightly connected
6.High pressure hoses should be tested within a year, prevent hose aging accidents, the hoses cannot be used when the experimental pressure lower than 900bar/13050PSI occurs humps or leakage.
