Rexroth hydraulic pump A10VG45

In the whole equipment, the hydraulic pump as a power output equipment, has a pivotal component. It's like a backbone in a community.

So in the selection of hydraulic pump, must be sure the brand and model. Our company has many years of equipment maintenance experience, the sale of high quality and low price of hydraulic pump products. The following is our company products hydraulic pump Rexroth A10VG45 display:

Knowledge development: answer: (1) prevent air invasion hydraulic system

At atmospheric pressure and normal temperature, the hydraulic oil contains air with volume ratio of 6 to 8%. When the pressure decreases, the time and space will be free from the oil, and the bubble rupture will make the hydraulic components "cavitation" and produce noise. A large number of air into the oil will make the "cavitation" phenomenon intensified, hydraulic oil compression increases, unstable work, reduce work efficiency, the implementation of components "crawling" and other adverse consequences. In addition, the air will also make the hydraulic oil oxidation, accelerate the deterioration of oil. Prevention of air invasion should pay attention to the following points:

The maintenance and change according to the provisions of the exclusion of air in the system, can be normal operation.

The hydraulic oil pump suction nozzle is not out of oil, oil pipeline must be sealed well.

The pump drive shaft seal should be good, should pay attention to the replacement of the seal should be the use of "lips" authentic seal, do not use the "single lip seal" instead of "single lip seal", because only one-way sealing oil, does not have the function of sealing gas. A unit has a Liugong ZL50 loader after overhaul, the hydraulic oil pump continuous "cavitation" noise, fuel tank oil level automatic rise higher fault, through the inquiry hydraulic oil pump repair process, found that the hydraulic oil pump drive shaft oil seal misuse "single lip" oil seal caused by.

(2) hydraulic system to prevent water intrusion

Excessive water content in oil will cause corrosion of hydraulic components, emulsification of oil, deterioration of lubricating oil film, and acceleration of mechanical wear.
