How to install check ZX type water self-priming pump

1, ZX-type water self-priming pump and the motor direct drive, you should pay attention to the coaxial output shaft and motor; pump installation accuracy or not on the smooth operation of the pump and life have a greater impact, it must Carefully install and correct. 2, the pump coupling must be tightened with the mother, and lock the nut, to prevent the mother loose, otherwise easy to cause the impeller to move, resulting in mechanical failure. 3, in order to pump the body to maintain a certain amount of storage solution, in order to achieve better self-priming capacity and prevent mechanical seal dry friction, the pump must be imported higher than the shaft centerline. 4, the suction pipe installation should be noted: a. Suction inlet installation height can not exceed 5 meters, when conditions permit, the suction inlet installation height should be as low as possible below the reservoir minimum storage level, and try to short suction pipe The length of less installed elbows, which is conducive to? Short self-absorption time, improve self-absorption function. b. Inhalation pipeline valves, flanges, etc. should be strictly prevent leakage or leakage of liquid, that is, the suction pipe is not allowed to have leakage phenomenon. c. Pumps should be prevented from inhaling solids and other debris, this suction pipe should be set on the filter. The effective flow area of ​​the filter should be 2-3 times the cross section of the suction pipe. The filter should be checked regularly. d. The suction line and discharge line should have their own support, the pump itself is not allowed to withstand the pipeline load. 5, the pump is installed, should make the electrostatic resistance of the pump and pipeline to meet the requirements of its grounding resistance. 6, the installation should be strictly seized pump casing and piping in the presence of stones, iron sand and other debris. 7, correction of pump coupling and motor coupling installation clearance and coaxiality, its different axis tolerance is 0.1 mm. The difference between the pump shaft and motor shaft height can be adjusted on the foot pad copper or iron. 8, ZX-type water self-priming pump in the actual operation 3-4 hours after the unit for the final inspection, if no adverse phenomena, then that the installation has been properly tested in the bearing temperature should be checked, the bearing body temperature should not exceed 70 ℃. 9, the pump bearing body cooling unit with a cooling water connector for the hole with Φ12 hose or plastic pipe, the thread size M12 × 1.75. 10, if the pump outlet pipe is equipped with a one-way valve in the process of self-priming can not make the pump discharge gas smoothly, should be added in the pump outlet exhaust pipe and valve. The use of the pump (a), self-priming pump before the start of the preparation and inspection work: 1. The self-priming pump, according to the working conditions of the pump, respectively, using high-quality calcium butter and oil No. 10 for lubrication, The pump should be filled regularly with grease in the bearing housing. Pump lubricated with oil. If the oil level is insufficient, add enough oil. 2, check the pump shell liquid is higher than the upper edge of the impeller.If not enough.From the pump housing on the liquid directly into the pump body into the reservoir, should not start under the condition of lack of liquid storage, Otherwise, the pump will not work properly and the mechanical seal will be damaged. 3, check ZX-type water self-priming pump rotating parts stuck magnetic touch phenomenon. 4. Check the pump foot and the joints at the nut loose or not. 5. Check the coaxiality and parallelism of pump shaft and 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.
