We are a professional enterprise engaged in the manufacture and sale of vp hydraulic vane pump.
It is characterized by high efficiency,saving energy,safety,can be used in hydraulic systems or volumetric regulation,for instance,cutting machine tools,pressure and leather machinery,shoe-making machinery,etc.
1,"Shaft clearance compensation"design,can according to the set pressure,automatically adjust the pump displacement.
2,The built-in pressure adjustment valve,hydraulic system no need to install pressure regulating valve.
3,Easy assembly,can combine directly with the electric motor.
4,Suitable for grinding machine,automatic lathe,machine tools,and other various special or single useful machine.
Delivery of unloading(l/min)
Directions for use:
Direction of rotation:clockwise(viewed from the shaft end)as the standard.Confirm the direction of roation can be checked from electric motor instant starting.
Hydraulic oil:7Mpa,40℃ viscosity 20-50cst(ISO VG32) of the hydraulic oil.
Oil pressure:vent pipe must be inserted directly into the oil tank under the surface,and the resulting back pressure piping,please maintain below 0.3kgf/c㎡.
Working temperature:Temperature of continuous opreation is 15-60℃.
Axis with:Eccentric error of pump and motor is 0.05mm,angle error is 1°.
Oil inlet pressure:-0.3kgf/c㎡ to 0.3kgf/c㎡.
Volume adjustment:When adjust displacement,loosen the adjust nut first,then rotate the adjust bolt,turn right to reduce emissions,and turn left to increase.When adjustment is completed,please tighten the nut.
Pressure adjustment:Turn left(clockwise)pressure adjust screw,so that the output pressure is reduced,turn right(clockwise) to increase.
Operation of the new machine:When new machine running,it should be repeated starting motor in a stress free state,to the exclusion of the pump and suction pipe in the air,to ensure the exclusion of air within the system,at no load conditions,continuous operation for 10minutes.
