Application and maintenance of high lift deep well pump

Classification:

The following describes the application and maintenance of high-lift deep well pumps High lift deep well pump in use to build a tripod. And use the hoist (chain hoist) and wooden card board to assemble the water supply pipe and rotating shaft section by section, and assemble the rotary table. When assembling, make the motor shaft, rotating shaft and water supply pipe in the same boat, and the three must be perpendicular to the plane.

The following describes the application and maintenance of high-lift deep well pumps

1. Operating methods and regulations

　　high lift deep well pumpWhen in use to build a tripod. And use the hoist (chain hoist) and wooden card board to assemble the water supply pipe and rotating shaft section by section, and assemble the rotary table. When assembling, make the motor shaft, rotating shaft and water supply pipe in the same boat, and the three must be perpendicular to the plane.

Fill the pump with water before starting. until the water drains through the drain. Since the rubber bearing in the rotating shaft is smooth with tap water, otherwise the rubber rolling bearing will be damaged or even burned too early because there is no water in the water supply pipeline in the starting process.

Before each start-up, check the moistening condition of each moistening point of the rotary table. If the rolling bearing is too high during operation, rotate the oil cup for a few turns. If the rolling bearing is still too high after lifting moistening, the rotary table needs to be disassembled and assembled. Check the condition of rolling bearings. Reuse after fault detection.

Do not turn the rotating shaft in the opposite direction. Check the phase difference of the motor before starting, otherwise the rotating shaft may derail if the turning time is long.

The packing shall not be pressed too tightly or too loose. 60~100 drops per minute can be leaked out.

2. Protection and maintenance

When applying, pay special attention to the operating conditions, and often check the temperature of the motor (can be tolerated by hand). If the temperature is too high, shut down and rest for 1-2h before starting.

When there is an abnormal sound, it is necessary to shut down in time to check the cause and detect the fault. The rolling bearings of the rotary table can use calcium-based, calcium-calcium-based or molybdenum disulfide lubricating fluid, and sodium-based grease that is easy to be decomposed by water cannot be applied.

Rolling bearings should be cleaned at least once every six months. Fill the grease again.

When long-term use is stopped, part of the rotary table should be waterproof and rainproof countermeasures.

　high lift deep well pumpAfter working for one year or one year, a comprehensive physical examination and maintenance should be done. If the application of one year later, the deep well pump does not appear in the operation of vibration, the current data information is normal, the maintenance period can be extended to 2 years.

For high-lift deep well pumps that have been in operation for less than one year, if it is found that there is a very large vibration around the pump during operation, it may be that the rubber bearing is damaged. At this time, the water supply pipeline should be clearly proposed section by section. Detect and replace the twisted rolling bearing.

During the maintenance of high-lift deep well pumps, the damage conditions of rubber bearings, centrifugal impellers and sealing rings should be carefully checked. If the damage is relatively large, it should be replaced. Check whether the anti-corrosion coating has fallen off. If there is a part to fall off, paint with a new anti-corrosion coating.

How to store, transport and anti-corrosion measures for high-lift deep well pumps For well pumps containing packed wooden boxes, they should be placed on a flat concrete floor. For deep well pumps without packed wooden boxes, they should be discharged flat on the pump rack with 3 support points. Both sides shall not be suspended in the air for more than 1m.
