1. Screw pumps are strictly prohibited to operate empty in the absence of liquid in the pump chamber. It is necessary to inject liquid into the pump body by the inlet of the pump before starting, and then start the screw pump, so as to avoid idling and wearing the stator of the screw pump. How to use screw pump?
2, before starting the screw pump, we must first determine the operation direction of the screw pump, and the screw pump can not reverse.
3. When the screw pump is newly installed or shut down for several days, it can not start immediately. It should also inject a proper amount of lubricant or liquid conveyed by the screw pump into the pump body, and then use pipe pliers to pull the screw pump several turns before starting.
4. When stainless steel screw pump transports high-viscosity liquid or corrosive medium, it should flush the cavity of screw pump with clean water or solvent to prevent blockage so as to avoid damaging the stator when starting screw pump next time.
5. When using single screw pump in winter, the volume fluid of the pump should be excluded when the temperature is too low to be used, so as to prevent the freezing crack of the pump body or the stator from being pulled out when the pump freezes next time it starts. How to use screw pump?
6. Lubricating oil should be added regularly in the bearing box during use. When seepage is found at the shaft end, oil seals should be treated or replaced in time.
7, in the event of abnormal operation, should immediately stop the reasons for pump inspection, troubleshooting.
