technical conditions
1, the sludge pump rotates smoothly and smoothly, without the phenomenon of death, stagnation, vibration and so on.
2. The seal pressure test of the sludge pump, the test pressure is 0.2Mpa.
3, the sewage sludge pump adopts double mechanical seal structure and lip seal structure, and the mechanical seal is guaranteed to operate reliably in 10000 hours without changing.
4, the sludge pump leads the cable to use the YZW rubber sheath soft cable or the same performance other cable, the cable seal head uses the special vulcanization processing, in order to prevent the cable outer skin to be damaged and seepage to the electric motor.
5. There is a seal leakage protection device in the sludge pump oil room.
6. The double color line (yellow / green) in the extraction cable of the sludge pump is defined as the grounding wire, and the connection is reliable. The ground sign is obvious, and it is not easy to wear out during the period of use.
7. The dynamic balance test of the motor rotor of the sludge pump motor is used, the balance precision is G6.3.
8. There is a heat protection switch in the stator winding of the sludge pump motor.
9, during the operation of the sludge pump, the deviation between the supply voltage and frequency and the rated value and the influence on the motor performance and temperature rise are in accordance with the regulations of GB755. The electrical performance of the motor conforms to the provisions of JB/T8092, JB/Z346 and GB5013.4.
10. The sludge pump is free to rise and fall on the guide rail support, which can be coupled quickly with the pre buried reflux tube, and the operation is stable and reliable.
