Hydraulic pump to provide pressurized fluid to a hydraulic device for hydraulic transmission, is a pump. Its function is to power machine (such as a motor and an internal combustion engine, etc.) of the mechanical energy into pressure energy of the liquid. Output flow can be adjusted according to the needs of the professional maintenance of imports is called a variable pump called quantitative pump hydraulic motor telephone traffic can not be adjusted. Piston: Professional maintenance of imported high volumetric efficiency of hydraulic motors, small leaks, can work under pressure, mostly for high power hydraulic system; but the complex structure, materials and processing high precision, expensive Specialized imported hydraulic motor, for oil requires high cleanliness. Generally when the gear pumps and vane pumps with piston pump can not meet the requirements. Providing pressurized liquid to a hydraulic element for hydraulic transmission, is a pump. Its function is to power machine (such as a motor and an internal combustion engine, etc.) of the mechanical energy into pressure energy of the liquid. Many factors affect the service life of the hydraulic pump, the pump itself in addition to the design, manufacture and some external factors associated with the use of the pump element (e.g. couplings, filter, etc.) selection, the process of test running operation are also related. Professional maintenance of imported hydraulic motors telephone, hydraulic motors, hydraulic pressure from Jinan Jing Jing Chong Chong Hydraulic Machinery Limited.
