Sewage disposal equipment maintenance attention to matters

Polaris environmental protection net news: 1, the sewage disposal equipment change smooth oil: respectively opened the sealed chamber and the inside of the motor oil hole screws, all of the sealed interior and smooth inside the motor oil, change new oil, ensuring smooth system to work normally. 2, check the sewage disposal equipment wearing parts: submersible pump impeller, retaining ring, shaft sleeve, bearing seat is wearing parts, etc. You should take the pump partial removed, can check the parts in good condition. It is forbidden to use damage and unqualified parts. 3, tear open pump shell rust prevention: spring before use, should open the pump shell at the next higher level, closing again after starting rotating impeller, in case the parts rust cannot be the normal starting and burning motor. The remaining of filling water is particularly important to the motor. 4, sewage disposal equipment boring machine: use 500 megohm meter measure the insulation resistance of submersible pump winding and shell, if the value is lower than 0. 5 ohms, should drive motor moisture. Boring method are: external boring method, current boring method and the combination of both to stop the boring method. External boring method is applied external heat source to stop treatment, commonly used measures are: (1) blow hot air: application of the electric heater blower ( Agricultural small submersible pump can use hair dryer) Blow hot air to get to the disposal of the purpose of boring; 2 bulbs baking: in the sealed box, application of around 200 w bulb to stop baking. Keep an eye on baking temperature not too high, should be controlled under 125 ℃; (3) current boring: can be according to the size of impedance and power of submersible pump motor three-phase winding in series or in parallel, then access a variable resistor, adjust the power flow for about 60% of the rated current value, current boring. 5, to ensure the sewage disposal equipment sealing: agricultural submersible pump seal request is very strict, when to change oil seal indoor smooth if discover oil turbidity and high water content, it must change the whole or a change in the sealing box or sealing ring, in order to ensure the sealing performance is good. 6, check the bearing sewage disposal equipment: check the motor partial upper and lower bearings, if discover wear or gap is too big, must be timely to change the new bearing, it is strictly prohibited to shake using 'being'. Inspection methods are as follows: if the motor running, 'MAO unter den' sound, and the cycle is proportional to the speed, and turn the rotor by hand taxing, is bearing rolling path is a bit acerbity or avulsed phenomenon; If the bearing inner intermittent 'stuck to choke' sound, turn the rotor by hand not sure of the dead, is ordinary ball rack damage to ball bearings, inner ring rupture or broken. Meet the above conditions, it is necessary to change the bearing, so as not to form larger damage. The sewage disposal equipment, ensure smooth bearing: the water filling submersible pump should check a change in upper and lower bearing chamber of skeleton oil seal and smooth lithium base grease. To ensure the bearing long-term work under smooth and good condition.
