High pressure gear pump design manual, shenzhen gear pump factory

The principle and characteristic of high pressure gear pump surface glue coating surface coating technology in our country in recent years has been widely used in equipment maintenance, applicable to all kinds of spare parts and equipment repair. Its working principle is to add molybdenum disulfide, metal powder, ceramic powder, and fiber and other special packing adhesive, surface coated directly on the material or parts, wear-resisting, corrosion resistance and other functions, mainly used for surface strengthening and repairing. Its process simple, flexible, safe and reliable, does not need special equipment, simply with good adhesive coating still good parts surface, after curing for renovation, often at room temperature control, will not make the parts Thermal equivalent effects and deformation, etc.

 

 

 

High pressure gear pump transmission is the use of two gear teeth meshing transmission of power and movement of mechanical transmission. According to the relative position of the gear axis, it is divided into parallel cylindrical gear drive, intersecting conical gear drive and staggered helical gear drive. It has the characteristics of compact structure, high efficiency and long life.

 

 

 

Large flow gear pump is equipped with safety valve as overload protection, the full backflow pressure of the safety valve is 1.5 times of the rated discharge pressure of the pump, and can also be adjusted according to actual needs within the allowable discharge pressure range. However, it should be noted that this safety valve cannot be used for the long-term work of the pressure reducing valve, and can be installed separately on the pipeline when necessary. View the pump from the outstretched end of the spindle, clockwise rotation. The application range of large flow gear pump can be used as transmission and booster pump in oil transportation system. In the fuel system can be used as conveying, pressure, injection fuel pump; In all industrial fields, can be used as a lubricating oil pump.
