The main purpose of hardening the rotor surface of a G-Type Sanitary Screw Pump is to enhance the rotor's wear and corrosion resistance, thereby increasing the pump's service life and operating efficiency.
During the operation of a screw pump, a sealed chamber is formed between the rotor and stator, and the rotor's rotation propels the medium for transmission. The medium may contain solid particles or be corrosive, which can cause wear or corrosion on the rotor surface. If the rotor surface is not hardened, long-term wear and corrosion will cause dimensional changes, affecting the pump's sealing performance and transmission efficiency.
Hardening treatments typically include quenching, carburizing, nitriding, and surface coating. These processes significantly increase the hardness and wear resistance of the rotor surface, thereby resisting wear and corrosion from the medium. Furthermore, hardening treatments make the rotor surface smoother, reducing friction between the rotor and the stator, and lowering the pump's energy consumption and noise. Therefore, it is very necessary to harden the rotor surface of the G-type Sanitary Screw Pump, which can not only improve the service life and working efficiency of the pump, but also reduce the maintenance cost and operation cost of the pump.
