PRODUCT DISPLAY
Precautions for hydraulic pump connection
Hydraulic pumps can be installed with supports or flanges, and the pump and prime mover should use a common foundation support.
● Hydraulic pumps can be installed with supports or flanges, and the pump and prime mover should use a common foundation support. Both flanges and foundations should have sufficient rigidity. Special attention: plunger pumps with a flow rate greater than (or equal to) 160L/min should not be installed on the fuel tank.
● Elastic couplings should be used to connect the hydraulic pump and the output shaft of the prime mover. It is strictly prohibited to install a pulley or gear driven hydraulic pump on the hydraulic pump shaft. If a pulley or gear must be connected to the pump, a pair of supports should be added to install the pulley or gear. The coaxiality error between the support and the pump shaft should not be greater than Φ 0.05mm.
● The oil suction pipe should be as short, straight, large, and thick as possible. Generally, a coarse filter with a nominal flow rate not less than twice the pump flow rate should be installed in the oil suction pipeline (the filtration accuracy is generally 80-180 μ m) . The drain pipe of the hydraulic pump should be directly connected to the oil tank, and the back pressure of the return oil should not exceed 0.05MPa. The suction and return nozzles of the oil pump must be 200mm below the oil level of the fuel tank. Special attention should be paid to not installing an oil filter on the oil suction pipeline of the plunger pump. The diameter of the stop valve on the oil suction pipeline should be one block larger than the diameter of the oil suction pipeline. The oil suction pipe
● The inlet and outlet ports of the hydraulic pump should be installed firmly, and the sealing device should be reliable, otherwise there may be air suction or oil leakage, which will affect the performance of the hydraulic pump.
● The self priming height of the hydraulic pump shall not exceed 500mm (or the inlet vacuum degree shall not exceed 0.03MPa). If a makeup oil pump is used for oil supply, the oil supply pressure shall not exceed 0.5MPa. When the oil supply pressure exceeds 0.5MPa, a pressure resistant sealing ring shall be used instead. For plunger pumps, it is recommended to use a backflow self priming method as much as possible.
● Before installing the hydraulic pump, it should be checked whether the depth of the installation hole is greater than the shaft extension length of the pump to prevent the occurrence of shaft jacking, otherwise the pump will be burned.
