China wholesale deep well borehole pumps

a small exhaust pipe and valve should be added to the outlet of the pump. If the temperature of the liquid in the pump is too high to cause difficulty in self-priming, you can temporarily stop it, and use the liquid in the spit line to flow back into the pump or directly replenish the liquid into the pump at the liquid filling port on the pump body. This will not only facilitate the discharge of gas from the outlet during the self-priming process, but also ensure that the pump is lighter. 5.

The installation height of the suction inlet should not exceed 5. Prevent the suction of solids and other impurities in the pump body. Check whether the nuts of the pump body bottom and each connection are loose. Check after 3-4 hours of actual operation of the unit. 7. This will help shorten the self-priming time and improve the self-priming function.

When the inlet pipeline is blocked, it should be eliminated in time; when the suction lift is too high, the pump installation height can be appropriately reduced. If it is insufficient, you can directly inject the storage liquid into the pump body from the liquid filling port on the pump casing. When the pump enters the normal infusion operation, that is, the self-priming process, special attention should be paid to the rise of water temperature in the pump. The valves and flanges in the suction pipe should be strictly prevented from leaking air and liquid, that is, no air leakage is allowed in the suction pipe. 2.

The pump China wholesale deep well borehole pumps must be fastened with a nut, and the nut must be tightened to prevent the nut from loosening, otherwise it will easily cause the impeller to move and cause mechanical failure. Use of self-priming pump 1.1 mm. Preparation and inspection work before starting: 1.2020-03-23The installation of the self-priming pump uses the installation of the self-priming pump 1. This series of self-priming pumps are lubricated with calcium butter and No
