How to protect agricultural submersible pumps?

During the slack season, the submersible pumps should be properly maintained to prolong their service life and ensure normal use during busy hours. 1. Check wearing parts: The submersible pump impeller, retaining ring, bushings and bearing seat are all wearing parts. First of all the pump should be removed, check the wearing parts are intact. Do not use damaged or unqualified parts. 2, replace the oil: respectively, open the seal chamber and the motor oil hole screw inside the sealed chamber and the motor all the internal release of lubricating oil, replace the new oil, to ensure the normal lubrication system work. 3, the demolition of the pump casing rust: spring before use, should be disassembled the pump casing, turn the impeller and then start to prevent rusting parts can not start normally and burn the motor. This maintenance is especially important for water filled motors. 4, to ensure that the seal: agricultural submersible pumps on the sealing requirements are very strict, in the replacement of sealed room lubricants, if you find the oil cloudy and high moisture content, you must replace or replace the entire seal box or seal ring to ensure that the seal Good performance. 5, dry the motor: Use 500 megohms table to measure the insulation resistance of submersible pump windings and the shell, if the resistance is less than 0.5 megohms, you should get rid of the motor moisture. Drying methods are: external drying method, current drying method and the combination of both at the same time dry. External drying method is the use of external heat source for processing, commonly used measures are: ⑴ hot air: the use of electric heater blower (small submersible pump available hair dryer) hot air blowing to achieve the purpose of drying; ⑵ bulb baking: Closed box, the use of several 200-watt light bulbs for baking. Note that the baking temperature can not be too high, should be controlled below 125 ℃; ⑶ current drying: According to the submersible pump impedance and power supply size of the motor windings in series or in parallel, and then access a variable resistor, adjust the current About 60% of the rated current value, power and dry. 6, to ensure bearing lubrication: water-filled submersible pump should check the replacement of the upper and lower end of the bearing housing skeleton oil seal and lithium-based grease. To ensure long-term bearing lubrication in good condition. 7, check the bearings: Check the motor part of the upper and lower bearings, if found to wear or clearance is too large, must be promptly replaced with new bearings, non-sick "improper use. Check the method is as follows: If the motor is running, resulting in "carbazole" sound, and the cycle and speed is proportional to, and feel trouble by rotating the rotor, the bearing raceway is a bit astringent or avulsion phenomenon; If the bearing intermittent The "哽 哽" sound, turning the rotor by hand when there is an indefinite dead, the ball is generally broken, the inner ring broken ball or broken. In the event of these circumstances, the bearings must be replaced to avoid further damage.
