The correct operation from the suction pump not only to ensure the normal operation of the pump to improve work efficiency, but also can improve pump life. Now to introduce the correct operation steps under the self-priming pump products. Self-priming oil pump self-priming pump operation steps First, the pre-start preparation and inspection work 1. This series pump, according to the working conditions of the pump, respectively, using high-quality calcium-based butter and oil No. 10 for lubrication, if the use of butter lubrication The pump should be regularly filled with grease into the bearing housing, the use of oil-lubricated pump, if the oil level is insufficient, then add enough. 2. Check whether the liquid in the pump casing is higher than the upper edge of the impeller. If it is not enough, you can directly inject the liquid into the pump body from the liquid inlet of the pump casing, and should not start running when there is not enough liquid. Pump does not work, and easy to damage the mechanical seal. 3. Check the rotating parts of the pump is stuck bump phenomenon. 4. Check the pump foot and the joints at the nut loose or not. 5. Check the coaxiality or parallelism of the pump shaft and the motor shaft. 6. Check whether the imported pipeline leakage, if leaks, we must try to rule out. 7. Open the suction line valve, slightly open (do not open) the outlet control valve. Second, start and operation 1. Start the pump, pay attention to the steering shaft is correct. 2. Note that there is no abnormal rotation when the sound and vibration. 3. Note that the pressure gauge and vacuum gauge readings, after the start when the pressure gauge and vacuum gauge readings after a period of fluctuation and stability, indicating that the pump has been on the liquid, the pump into the normal oil operations. 4. During the process of self-absorption (or stripping) before the pump enters the normal oil transportation, pay special attention to the water temperature rising in the pump, if this process is too long, the water temperature inside the pump is too high, then stop the pump to check the reason . 5. If the pump liquid temperature is too high and cause self-absorption difficulties, then you can temporarily shut down, the use of the discharge pipe back to the pump back to the liquid pump or pump to the reservoir on the liquid directly to the pump to replenish the liquid so that Pump liquid cooling, and then start. 6. Adjust the outlet control valve so that the pressure gauge readings point to the specified area to avoid the pump within the lower limit of the prescribed area to prevent the motor overload due to excessive shaft power or pump cavitation due to excessive flow , Affecting the normal operation of the pump, the pump strong vibration, make noise. 7. Pump in the course of work as a strong vibration and noise, there may be pump cavitation caused by cavitation have two reasons: First, the import pipe flow rate is too large, the second is the suction stroke is too high. When the flow rate is too large, the outlet control valve can be adjusted to increase the pressure gauge readings, which should be promptly removed when there is a blockage in the inlet pipe. When the suction stroke is too high, the installation height of the pump may be properly reduced. 8. pump in the course of work for some reason to stop the pump, need to start again, the outlet control valve should be slightly open (do not fully closed), so that both self-priming gas discharge from the spit, but also to ensure that the pump is lighter Under the load of the start. 9. Pay attention to check the pipeline system for leakage. Third, stop the pump 1. First of all, must close the discharge valve on the pipeline. 2. Stop the pump. 3. In the cold season, the pump body should be stored in the liquid storage tank and the water cooling chamber to prevent cracking parts.
