YCB arc gear pump

1 Overview
It is suitable for transporting lubricating oil without solid particles and fibers, the temperature is not higher than 300℃, and the viscosity is 5x10-6~1.5×10-3m2/s (5-1500cSt) or other liquids similar to lubricating oil, reducing the pump Speed, the viscosity of the conveying medium can reach 5×104cSt. If transporting, filling, dumping light oil products such as liquefied petroleum gas, gasoline, kerosene, aviation oil, etc., sliding vane pumps can be used instead.

2. Application range
Can be used as transmission and booster pumps in oil delivery systems
It can be used as a fuel pump for delivery, pressurization and injection in the fuel system;
It can be used as a hydraulic pump to provide hydraulic power in the hydraulic transmission system;
It can be used as a lubricating oil pump in all industrial fields.

3. Structural features
This series of gear pumps are mainly composed of gears, shafts, pump bodies, pump covers, bearing sleeves, and shaft end seals. The gear is made of double-arc sinusoidal tooth profile. Compared with involute gears, its most prominent advantage is that there is no relative sliding on the tooth profile surface during the gear meshing process, so the tooth surface has no wear, stable operation, no liquid trapping, low noise, long life and high efficiency. The pump gets rid of the shackles of traditional design, making the gear pump enter a new field in design, production and use.
The pump is equipped with a safety valve as overload protection, and the total return pressure of the safety valve is 1.5 times the rated discharge pressure of the pump. It can also be adjusted according to actual needs within the allowable discharge pressure range. But note that this safety valve cannot be used as a pressure reducing valve for long-term operation, and can be installed on the pipeline when necessary.
The pump shaft end seal is designed in two forms, one is a mechanical seal and the other is a packing seal, which can be determined according to the specific use conditions and user requirements. Looking at the pump from the extended end of the main shaft, it rotates clockwise.
