Deep well submersible pump use and maintenance

1. Deep well submersible pump use and requirements
    The deep well submersible pump should be installed in the installation of the tripod and with a chain (chain hoist) and a board to install a section of water pipes and drive shaft. Finally install the power head. Installation should be the motor shaft, drive shaft and water Concentric, and the three must be perpendicular to the horizontal plane.
    Before the start of the water should be poured into the pump until the water from the outlet out so far because the rubber shaft on the drive shaft is lubricated with water, or in the start-up phase due to water in the water pipe and wear too early wear and tear, or even burn Bad.
    Each time before starting the power head should check the lubrication of the lubrication point, such as the operation of the bearing retraction is too high, the oil cup can be rotated into one or two laps, such as strengthening the lubrication after the bearing is still too high, you must remove the power Check the bearing situation. Remove the fault before use.
    The drive shaft of the steering can not be reversed, before starting to check the motor phase, or reverse the time may be slightly longer off the drive shaft.
    Seal packing can not be too tight or too loose. Every minute out of water 60 to 100 drops can be.
2. Deep well submersible pump maintenance and maintenance
    In the use of attention to observe the operation, often check the motor temperature rise (hand touch can be tolerated to limit.) If the temperature is too high to stop 1-2h and then start.
    When there is abnormal sound, it should be shut down in time to check the cause, troubleshooting. Power head of the bearings can be used calcium, calcium sodium or molybdenum disulfide lubricant, should not be easy to use water decomposition of sodium-based grease.
    At least once every six months should be cleaned once the bearings. Re-filling grease.
    Long-term suspension, the power head should be made of moisture and rain measures.
    Deep well pump working hours up to six months or a year later, should conduct a comprehensive inspection and maintenance. If a year later, the deep well pump does not vibrate during operation, and the current data is normal. The overhaul period can be extended to two years.
    For those who run less than one year of deep well pump, if found to have a large vibration around the foundation, it may be rubber bearing wear, then the water pipe should be raised one by one.Check and replace the damaged bearings.
    Deep well pump in the overhaul, should carefully check the sections of rubber bearings, impeller, seal ring wear, such as wear and tear should be replaced; check whether the asphalt anti-corrosion coating off.If the shed part should be painted new asphalt coating The
