1. When the auto -absorbing sewage pump and the motor are directly connected, pay attention to the same axis of the pump shaft and the motor output; the accuracy of the pump installation has a great impact on the stability of the pump and the service life of the pump. Therefore, we must carefully and serious Estimation and correction.

2. The pumping shaft must be tightened with the aunt, and the nuts are locked to prevent the mother -in -law from loosening, otherwise it will easily cause the impeller to move and cause mechanical failure.

3. In order to keep a certain storage fluid in the pump body to achieve good self -absorbing ability and dry rubbing that prevent mechanical sealing, the import of pump imports must be higher than the central line of the pump axis.

4. Installation of self -absorbing sewage pump inhaled pipelines should be noted:

a. Installation height of the inlet port cannot exceed 5 meters. When conditions permit, the installation height of the inhaled mouth should be as low as the lowest water storage plane of the pool as much as possible, and the length of the suction pipe should be cut as little as possible. It is conducive to shortening self -suction time and improved self -suction function.

b. Valves, flanges, etc. in the pipeline should prevent leakage or leakage liquid, that is, the inhalation pipeline does not allow the phenomenon of air leakage.

c. The self -absorbing sewage pump should prevent sundry such as solids in the pump body. To this end, a filter should be set on the pipeline. The effective overcurrent area of the filter should be 2-3 times that of the inhaled pipe section, and the filter should be checked regularly.

d. Inhale pipelines and spit pipes should have their own brackets, and the pump body itself does not allow the load of the pipeline.

5. When installation, the static grounding resistance of the pump and pipeline should meet its requirements.

6. When installation, strictly check the pump shells and tubes whether there are stones, iron sand and other debris.

7. Correct the installation gaps and coaxiality of the motor bracket shafts of the pump, and the allowable deviation of different axis is 0.1 mm. The height difference between the pump shaft and the motor axis can be adjusted on the bottom of the bottom foot.

8. After the actual operation of the unit is running for 3-4 hours, the self-absorbing sewage pump is performed for the final inspection. If there is no adverse phenomenon, it is considered to be installed. In the trial operation, the temperature of the bearings should be checked. The temperature of the bearings should not exceed 70 ° C.

9. If a unidirectional valve is equipped on the exit pipeline of the pump, when the pump cannot be discharged smoothly during the self -priming process, the exhaust tube and valve should be added to the exit of the pump.
