Coupling assembly requirements: the coaxiality error of the two shafts of the rigid coupling is ≤0.05mm;hydraulic pump the coaxiality error of the two shafts of the elastic coupling is ≤0.1mm;hydraulic pump the angle error of the two shafts is<1°; the drive shaft and the pump The end should maintain a distance of 5~10mm;
The selection of hydraulic oil tank, the main function of hydraulic oil tank in hydraulic system is oil storage, hydraulic pump heat dissipation, separation of air contained in oil and elimination of foam. When selecting a fuel tank,hydraulic pump the capacity must be considered first. Generally, mobile equipment takes 2~3 times the maximum flow rate of the pump,hydraulic pump and fixed equipment takes 3~4 times; secondly, consider the oil level of the fuel tank. When all the hydraulic cylinders of the system extend, the oil level of the fuel tank should not be low. At the lowest oil level,hydraulic pump the oil level shall not be higher than the highest oil level after the oil cylinder is retracted; finally,hydraulic pump considering the structure of the oil tank,hydraulic pump the baffle in the traditional oil tank cannot play the role of depositing dirt. A vertical baffle should be installed along the longitudinal axis of the fuel tank.
There is a space between one end of the partition and the end plate of the oil tank to connect the spaces on both sides of the partition. The oil inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the unconnected end, so that the distance between the oil inlet and the oil return is the farthest. The hydraulic oil tank has more heat dissipation effect.
