Self-priming sea pump and the pump on the ground there is a big difference, Xiaobian tell you now, self-priming sea water pump to use the correct method and in the operation should pay attention to the matter. Sea pump First, before the start of the inspection 1, Self-priming sea water pump, according to the working conditions of the pump, respectively, using high-quality calcium-based butter and No. 10 oil for lubrication, if the pump with butter lubrication should be regularly to the bearing box Fill the butter with a pump lubricated with oil and add enough if the oil level is low. 2, check the pump casing is higher than the upper edge of the impeller, if not enough, you can pump casing from the liquid directly into the pump body injection liquid storage should not start running under insufficient liquid storage , Otherwise it can not work, and easy to damage the mechanical seal. 3, check whether the rotating parts of the pump bump card phenomenon. 4, check the pump foot and the joints at the nut loose phenomenon. 5, check the pump shaft and motor spindle coaxiality and parallelism. 6, check whether the import pipeline leakage, if leaks, we must try to rule out. 7, open the suction pipe valve, slightly open (do not fully open) outlet control valve. Second, starting and operation 1, jog seawater pump, pay attention to the steering shaft is correct. 2, pay attention to whether there is no abnormal rotation and vibration. 3, pay attention to the pressure gauge and vacuum gauge reading, after the start when the pressure gauge and vacuum gauge readings after a period of fluctuation and indicate stability, indicating that the pump has been on the liquid, into the normal infusion operation. 4, the pump into the normal infusion operation before self-absorption process, special attention should be paid to increase the pump temperature, if this process is too long, the pump temperature 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 liquid back to the pump back to the pump or to the pump body plus reservoir directly to the pump to replenish the liquid, so that the pump The liquid cooling, and then start. 6, the pump in the course of work as a strong vibration and noise, there may be caused by pump cavitation, cavitation produced for two reasons: First, the import pipe flow rate is too large, and second, 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. 7, the pump in the process of work for some reason to stop the pump, need to start again, the outlet control valve should be slightly open (not fully closed), so that it is conducive to spontaneous discharge gas discharge from the outlet, but also to ensure that the sharp tip Under the responsibility of starting. 8, pay attention to check the pipeline system leakage. Third, stop the pump 1, must first close the discharge valve on the pipeline, so that the pump stops rotating. 2, in the cold season, the liquid should be stored in the pump body and bearing body cooling water in the room to vent, in order to prevent cracking parts.
