FQW30-18/W pneumatic submersible pump for mine

Fqw30-18 /W Mine pneumatic submersible pump use, maintenance and maintenance

1, the new pump before use, must be a test run on the ground. In ground air transportation, the air pressure should be controlled within 0.2Mpa and the test pump time should not exceed three minutes to avoid high-speed operation, accelerate the wear of parts and reduce the service life.

2. The inner diameter of the intake pipe shall not be less than 25mm, and the working pressure shall not be less than 0.5mpa, otherwise the normal work will be affected;

3, in the installation of the intake pipe, the pipe and the joint of the impurities to blow clean, ensure that the intake of dry clean, so as not to impurities into the parts caused by wear or rotor stuck unable to operate.

4, water wheel nut must add spring washer, in case of backwater rotor inversion loose, resulting in impeller sinking and pump body friction.

5. During the installation and disassembly of vulnerable parts such as impeller, turbine and sealing ring, heavy hammer should not be used to avoid damaging the fitting accuracy of internal parts. Generally in the continuous use of about 15 days, the air pump should be opened for cleaning, maintenance.

6, sewage air pump can be used in the muddy water containing rock powder and sediment more, through ≤10mm particles, not because of small solid particles or fiber inhalation and blockage, also not because of the inhalation of abrasive media and premature damage.

7. The exhaust pipe shall be exposed to the water, and water and other impurities shall not be allowed to enter the exhaust pipe, so as to avoid the corrosion of internal parts of the cylinder or the blockage of impeller and rotor.
