气体增压泵厂家为您揭秘液压泵的种类

Common types of hydraulic pumps.

按流量是否可调节可分为.变量泵和定量泵.输出流量可以根据需要来调节的称为变量泵.流量不能调节的称为定量泵.

According to whether the flow can be adjusted to be divided into variable pump and quantitative pump. The output flow can be adjusted according to the need to adjust the variable pump.

按液压系统中常用的泵结构分为.齿轮泵.叶片泵和柱塞泵3种.

According to the hydraulic system, the pump structure is divided into 3 kinds: gear pump, vane pump and piston pump.

齿轮泵.体积较小.结构较简单.对油的清洁度要求不严.价格较便宜;但泵轴受不平衡力.磨损严重.泄漏较大.

Gear pumps. Small size, relatively simple structure, the requirements of the cleanliness of the oil is not strict. The price is cheaper, but the pump shaft is not balanced.

叶片泵.分为双作用叶片泵和单作用叶片泵.这种泵流量均匀.运转平稳.噪音小.作压力和容积效率比齿轮泵高.结构比齿轮泵复杂.

Vane pump. It is divided into two - acting vane pump and single acting vane pump. The pump is uniform, stable, low noise, high efficiency of pressure and volume ratio.

柱塞泵.容积效率高.泄漏小.可在高压下工作.大多用於大功率液压系统;但结构复杂.材料和加工精度要求高.价格贵.对油的清洁度要求高.

Piston pump. The volume efficiency is high, the leakage is small. It can work under high pressure. It is mostly used for large power hydraulic system, but the structure is complex, and the precision of the material and processing is high.
