First of all, Dongxing Pump Industry here reminds everyone how to properly use and protect the stainless steel gear pump. Stainless steel gear oil pumps often have some short service life in use. The main reason is that the choice of stainless steel gear oil pump is not enough to understand the medium conveyed by the pump. The material selection of the pump is not accurate enough. The general stainless steel gear pump is generally used for the gear pump body. 304 stainless steel material, the gear is made of 304 stainless steel or 2Cr13 material, and heat treatment or nitriding treatment is carried out at the same time. Most of the bearings are made of stainless steel bushings and steel back composite sleeves. The main shaft is mostly 23Cr13. The actual material combination is for conveying lubricious medium. It is ok, but if it is used to transport media containing impurities or poor lubricity and poor lubricity, the hardness of the material is not large enough, and the wear resistance and fatigue resistance of the material are poor, in the case where the gear pump is concentric with the motor. The gear wear is slightly slower. If the concentricity of the gear pump and the motor is slightly worse, each component of the gear pump will wear very quickly. Once the shaft and gear of the gear pump wear out, the shaft will jump and then seal to cause leakage.
Secondly, stainless steel gear oil pumps generally transport more acid-base media, and such media tend to have very low viscosity. Due to the large coefficient of thermal expansion of 304 stainless steel, the general manufacturer considers that the impact of temperature rise will easily cause the gear pump to lock and hold the shaft when assembling the stainless steel gear pump. Therefore, the general clearance will be biased when assembling the stainless steel gear pump. Bigger. Due to the low viscosity of the conveying medium, the large internal clearance of the pump will cause the stainless steel gear pump to not suck or flow and the head is insufficient.
