How to protect the agricultural submersible pump?

Slack season, should be necessary for agricultural submersible pump to maintain the necessary maintenance to extend its service life and ensure busy when the normal use:
1, check the wearing parts: submersible pump impeller, guide vane, machine seals, bearings, etc. are wearing parts.
2, the replacement of lubricants: open the sealed chamber and the motor inside the oil hole screws, the sealed indoor and motor internal lubricants all release, replace the new oil to ensure that the lubrication system to work properly.
3, the demolition of the pump shell rust: spring before use, should be opened the last level of the pump shell, turn the wheel after the closing start to prevent the parts rust can not start normal and burn the motor. This maintenance is particularly important for water-filled motors.
4, to ensure that bearing lubrication: water-filled submersible pump should be checked to replace the upper and lower end of the bearing chamber skeleton oil seal and lithium grease. To ensure that the bearing long-term work in a good state of lubrication.
5, check the bearing: check the motor part of the upper and lower bearings, if found to wear or clearance is too large, to be timely replacement of new bearings, is strictly prohibited "sick" improvise.
Check the method is as follows: If the motor is running, resulting in "carbazole" sound, and the cycle is proportional to the speed, and hand when the rotor is laborious, bearing raceway is a bit astringent or avulsion phenomenon; if the bearing intermittent Of the "choking choked" sound, hand rotation of the rotor when there is uncertainty of the dead point, the ball is generally damaged, broken inner ring or broken ball. Encountered the above situation, you must replace the bearings, so as to avoid greater damage. our website:www.shwhpump.com,email:fay@welpump.com
