Marine YCB Series Circular Gear Pump
1. Application
It applies to delivering non – corrosive lubricating – oil or equivalent liquid without solid particles and fibres at temperature below 300°C, with the viscosity of 5×10−6−1.5×10−3m2/s (5 – 1500cSt), and other liquids similar to lubricating oil as well as hydraulic drive systems. Reducing the speed, the pump can deliver liquid with viscosity up to 5×106cSt.
2. Application Scope
- In oil delivery systems, it can serve as a transfer pump or booster pump.
- In fuel supply, pressurization, and injection systems, it can act as a fuel pump.
- In hydraulic systems, it can be used as a hydraulic pump to supply hydraulic power.
- In all industrial fields, it can be used as a lubricating pump.
3. Structure Features
YCB series gear pumps are mainly composed of gears, axles, pump body, pump cover, safety valve, and axle – end seals, etc. (Special requirements: magnetic force drive and zero – leakage structure can be selected). The gears adopt double – circular – arc tooth shape with a special conjugating curve. This shape makes the gears have less wear on the gear surface, stable revolution, low noise, long service life, and high efficiency. Due to no sliding on the teeth during gear running – in, this kind of pump has got rid of traditional design and entered a new era in design and application.
The pump is designed with a safety valve for protection against overloading. The full return flow pressure is 1.5 times higher than the rated exhaust pressure of the pump. It can be adjusted within the allowance of exhaust pressure range according to circumstances. But note that the safety valve can’t be applied as a pressure – reducing valve for a long time. You may install a pressure – reducing valve separately on the pipeline if needed.
There are two kinds of axle – end seals: mechanical seal and packing seal, which can be chosen according to the clients’ requirements or application circumstances. The direction of rotation is clockwise viewed from the coupling end.
