Characteristics of YDZ series hydraulic pump
The Z-series hydraulic pump is a medium pressure gear pumpwith an alloy aluminum pump body. The bearing is a classicdouble 8-shaped sleeve structure.In order to achieve responsivepressure and good volumetric efficiency, high-pressure oil floatingstructures are used on both sides of the 8-shaped sleeve. Thisstructure is an important measure to establish pressure andensure volumetric efficiency. The bearing part is made of integralcopper based powder metallurgy material, which has good di-mensional stability and lubrication. The pump body adopts aspiral tooth structure, which greatly reduces the noise during operation. Due to the use of the spiral tooth structure, the pressureoil obtained is less pulsating
