Gear pumps are generally used in construction machinery and work environment is not high precision general machine tools, and the pressure is not too high and the flow of hydraulic systems. Gear pump advantages: 1, simple structure, better technology, lower cost. 2, compared with other types of pumps of the same flow, compact structure, small size. 3, self-priming performance is good. Speed ​​even in manual conditions can be reliably self-priming 4, the speed range is large because of the pump drive parts and gears are basically balanced, at high speeds will not have a larger inertial force 5, the oil Liquid dirt on its work is not serious, not easy to kill. Gear pump shortcomings: 1, the work pressure is low .YCB10-0.6 gear pump gears, shafts and bearings on the pressure imbalance, radial load, Limiting its pressure to improve .YCB10-0.6 gear pump is mainly used for low pressure system. 2, lower volumetric efficiency.This is due to YCB10-0.6 gear pump end face leak.3, flow pulsation, causing pressure pulsation, Make pipes, valves and other vibration, noise.
