Gear pump is a new product independently developed by our company, specially used for heavy shovel machinery.
Machinery such as: crawler crane, pile driver, port equipment, roadheader, front crane, excavator, roller, concrete pump truck.
公司经营起重机、履带式打桩机、港口机械堆高机、船舶用泵、小松、挖掘机、CAT、等的工业用品液压泵、齿轮泵、马达、柱塞泵。
齿轮泵及马达与柱塞泵内部的零件磨损和壳体的磨损，还有油封磨损，油封老化等问题。泵内部零件的磨损会造成内漏，其中轴套和齿轮端面之间泄漏面积大，是造成漏油的主要部位。磨损内漏是齿轮泵容积效率，造成泵输出功率远远小于输入功率。因为齿轮柱塞在壳体内不停的旋转，必然会产生一定的热能，很容易引起泵过油，加剧零部件磨损。壳体的磨损主要是轴套孔的磨损，（齿轮轴与轴套的正常间隙0.09~0.175mm，大不得超过0.20mm）。
The company operates crane, crawler pile driver, port machinery stacker, Marine pump, komatsu, excavator, CAT, and other industrial supplies hydraulic pump, gear pump, motor, piston pump.
Gear pump and motor and piston pump internal parts wear and shell wear, as well as oil seal wear, oil seal aging and other problems. The wear of the pump internal parts will cause internal leakage, which is caused by the large leakage area between the shaft sleeve and the gear end face, is the main part of oil leakage. Wear leakage is gear pump volume efficiency, resulting in pump output power is far less than the input power. Because the gear plunger keeps rotating in the shell, it is bound to produce a certain amount of heat energy, which is easy to cause the pump over oil and aggravate the wear of parts. The wear of the shell is mainly the wear of the shaft sleeve hole, (the normal gap between the gear shaft and the shaft sleeve is 0.09~0.175mm, not more than 0.20mm).

齿轮泵及马达使用注意说明：
1、 严禁用户自行拆卸，否则生产厂家不能产品的性能与质量。
2、 泵或马达所在的液压系统过虑装置精度很小，油液中不得混有机械杂质和腐蚀物质，容易形成油路阻塞而造成的损失。
3、 泵或马达的安装，进出油口应安装牢固，密封装置要可靠，否则吸入空气或漏油现象，影响泵或马达的性能。
我这边就简单的说一下，咨询客服，下单后会告诉你全过程。
Gear pump use notes:
1. Users are strictly prohibited to disassemble by themselves, otherwise the manufacturer cannot guarantee the performance and quality of the product.
2. The precision of the hydraulic system alarming device where the pump or motor is located is very small, and the oil shall not be mixed with mechanical impurities and corrosive substances, which is easy to form the loss caused by oil blockage.
3, the installation of the pump or motor, the inlet and outlet of the oil should be firmly installed, the sealing device should be reliable, otherwise the inhalation of air or oil leakage phenomenon, affect the performance of the pump or motor.
I will tell you the whole process after placing an order after consulting customer service. Whatsapp+86-
