Stainless steel single screw pumpIt can be used to transport neutral or corrosive liquids, clean or abrasive liquids, liquids containing gases or easily producing bubbles, high viscosity or low viscosity liquids, including liquids containing fibers and solid substances. It can work continuously for a long time while maintaining a stable flow rate and has good self-priming ability.
Trial operation and fault analysis of stainless steel single screw pump:
Before starting the pump, the conveyed medium must be injected into the pump suction chamber. If the concentration of the medium is too high, it should be diluted before injection. This infusion measure is necessary for lubricating the rubber stator. Then, at the coupling between the pump and the motor, use a plate clamp to move the drive shaft, so that the drive shaft drives the screw rotor to rotate 3-5 revolutions, and then turn on the power to start. Otherwise, the lack of medium lubrication inside the rubber stator will result in dry grinding, making it difficult to start and even damaging the rubber stator.
If the pump needs to be stopped for a short period of time during operation, it should be ensured that sufficient medium remains in the pump as lubrication for the stator during restart. Users should consider this when designing pipeline layouts.
The G-type single screw pump is a positive displacement pump and cannot operate when the valve is closed. If the outlet pipeline is blocked or the valve is accidentally closed, the pressure of the pump will sharply increase to several times the rated pressure, resulting in damage to the pump or pipeline rupture. This situation must be avoided when transporting hazardous media. Therefore, it is essential to install safety devices such as pressure switches.
The pump with adjustable stator can be adjusted by fitting eight screws on the stator adjustment sleeve to compensate for the worn stator and extend its service life. The adjustment method is shown on the attached page.
Before starting, it is necessary to confirm that all components and safety devices have been installed correctly before starting up.
Check if the pump shaft rotation direction is correct by instantly connecting the motor.
When the pump is stopped in an environment temperature that may cause the medium to freeze, it should be ensured that the pump is emptied to prevent freezing and cracking. The pump is equipped with a drainage hole below the connecting body.
Pumps that transport media that are prone to sedimentation and solidification should be cleaned regularly. The cleaning interval time is determined by the operator due to the different media and operating methods used for transportation.
