Submersible sewage pump custody and use skills

Submersible sewage pump in the municipal construction, water treatment and other industries have a large number of applications, due to the harsh environment, the sewage pump requirements are high, so, in use, the submersible sewage pump custody and use To special attention. Submersible sewage pump custody and use of skills (1) Check the wearing parts. First of all remove the pump part, check the impeller, buckle, sleeve and bearing consumables are intact. Good can continue to use the pump assembly, bad must be replaced. (2) for lubricating oil. Respectively, unscrew the seal chamber and the motor within the hole screw, the sealed chamber and the motor all the internal release of lubricating oil, replace the new oil. (3) to ensure that the seal. When changing the oil in the sealed chamber, if it is found that the oiliness is cloudy and the water content has exceeded 50mL, the moving, static sealing ring or sealing box must be replaced or replaced as a whole. (4) dry. On the insulation resistance of less than 0.5mΩ motor windings, must be dried, dry method with the general motor. If the whole or sealed box is not replaced, you can only remove the stator part of the pump. Under normal circumstances, the whole or sealed box should be as much as possible disassembly, if you really want to disassembly, O-ring rubber seals must be replaced. (5) Check the bearings. Check the motor part of the upper and lower bearings, found excessive wear or clearance is too large, the timely replacement of new bearings. (6) Confirm that the parts are not rusty. Before use should be disassembled pump casing, turn the impeller and then closed to prevent corrosion of parts can not start normally and burn motor windings. This maintenance is especially important for water-filled motors. (7) Make sure the bearings are well lubricated. Water-filled submersible pump should replace the upper and lower cover shaft seal oil seal and lithium-based grease to ensure that the bearing in the work can get good lubrication.

1. Use Surface Mount System to install electron component. High quality stable and more quality consistency.

2. Pass germany TUV testing, have EMC and LVD certificate.

3. The AC input power voltage is made between 85V to 240V. So it could select AC input voltage automatically. You could work in AC USA 110V or AC europe 220-240V.

4. CEL: Cellulose electrode is special electrode to lay big pipe on oil and chemical industry, natural gas, electric power, civil pipeline of oil, gas, water. They need high ilder voltage (more than 90V). This machine could do
