Hydraulic gear pump installation, base or bracket should have sufficient stiffness, the hydraulic gear pump in the twisting force generated by the rotation of the shaft, and should not be subjected to other force; coupling between different axes is not greater than 0.05mm; hydraulic gear pump should be according to the direction of rotation of the calibration operation, pay attention to import the oil outlet position, big hole inlet.

The hydraulic system must set the safety valve, the same is slim, the tank must be to prevent dust, sand and other debris into the oil and regular cleaning, oil pipeline as short as possible, not more than 500mm, should minimize the use of elbow, the piping shall not leak phenomenon.

Working fluid regulation: use HC-8# diesel engine oil in winter, use HC-11# diesel engine oil in summer, working temperature is -10 degrees to 70 degrees.

Installation requirements:

The driving shaft of pump is not allowed to bear radial force and axial force (such as: installation connection spline sleeve length shall not exceed the effective length, pump power and drive shaft spline shaft end coupling sleeve and shaft spline gear pump can not have any step closure and shaft axial offset exists). Special conditions, such as radial force and axial force, please contact the company for special orders.

The installation shaft of the pump drive shaft and the output shaft of the prime mover shall not be greater than 0.05mm, and the mounting plane of the pump support and the verticality of the check mouth shall not be greater than 0.05mm. The connecting parts at the ends of the connecting shaft should also ensure the coaxiality within 0.05mm.

Pump suction height is less than 0.5m, and the oil inlet pipe size should ensure the flow rate less than 2m/s, namely the oil inlet pipe size (d = 3.25 mm), where Q is the pump inlet flow Q (L) =q - n.

The oil inlet pipe and flange of the pump shall not leak.
