Electric hydraulic pump main role

Electric fluid pump is an important part of the hydraulic wrench, hydraulic fluid pressure to provide a hydraulic components, electric hydraulic pump directly affects the quality of life of the hydraulic wrench. Electric hydraulic pump with air pressure tank, there are hydraulic pump itself with a charge pump to the hydraulic pump inlet to provide pressure oil. With the increasing popularity of such products, understanding the role of electric hydraulic pumps is of great importance to new users. The main role of electric hydraulic pump Electric pump self-priming hydraulic pump self-priming oil capacity is strong, no external oil supply. After each time you start the machine, you must wait for the hydraulic box to reach the operating pressure before operating the machine. If the pressure of the hydraulic tank is low, it will cause the pull-off phenomenon in the hydraulic pump and the slippery whip, which will cause abnormal wear of the return plate and the pressure plate in the pump body. Electric hydraulic pump has the following effects: 1, anti-corrosion, anti-fouling ability. 2, Adjustable pressure valve, easy to recalibrate working pressure, card to prevent pressure overload; 3, Lightweight compact design, to adapt to construction, ships and other harsh working conditions; 4, Most models come standard with motor starter overload , Overheating and leakage protection; 5, durable reversing valve for single-acting cylinder and double-acting cylinder; optional electromagnetic reversing valve remote operation; PLC control pump station optional 6, two-speed pumping station design, low pressure Large flow, no-load implementation of the rapid movement of components, built-in high-precision high and low pressure automatic switching valve; In addition, when using hydraulic wrench, the user needs to check the plunger pump, preferably 1-2 times a day to check the hydraulic pump running sound Is it normal? Because the electric hydraulic pump with a charge pump piston pump. If you find that the hydraulic cylinder speed drop or boring car, should respond to the charge pump disintegration inspection, check the edge of the impeller scratches, internal gear pump clearance is too large. Hydraulic wrenches on a regular basis to inspect the electric hydraulic pump to ensure that the electric pump hydraulic "health", but also can effectively extend the service life of hydraulic wrenches.
