Stainless steel submersible pump daily inspection and maintenance

Stainless steel submersible pump products excellent performance, stable operation, every pump before they go out to the strict testing, permanently lubricated ball bearings and interior operation of the high quality mechanical seal oil make submersible water pump has maximum durability, however, in order to ensure the service life of the stainless steel submersible pump, it is recommended to use the unit for regular inspection and maintenance.

stainless steel submersible pump inspection and repair

1. Regularly check the pump and motor, and the insulation resistance of the contrast between its value should be greater than 2 m Ω, otherwise should dismantle machine maintenance ( Dry processing) , at the same time, should check whether the grounding is strong.

       2. Impeller and tear institutions ( The base plate) The gap between 0. 3 to 0. 5 mm, after long-term use in medium, the gap could increase as a result of wear and tear, at this time should be adjusted, the method is as follows: disconnect the power supply, loosen the set screw, rotating an appropriate Angle plate can restore the original clearance.

       3. After repeated use stainless steel submersible pump must be in the clear water after running for a few minutes, to prevent the pump cavity leaves sediment, affect the normal use sewage pump.

       4. Stainless steel submersible pump medium used in regulations after six months, should check the oil chamber sealing condition, replace # 10 ~ 30 # engine oil, if necessary, replace the mechanical seals, for use in working conditions of the sewage pump should be check. Oil change method is as follows: the pump in place, make the oil chamber plug ( Medial to the outlet) Down, release lubricating oil, and then clean with washing oil oil room, to the right amount of oil ( 70% ~ 80%) Change the new o-rings, and tighten screw.

       5. Finds water (such as waste oil Milky emulsion) Cleaning oil chamber by the regulation pay equal attention to the new oil, used must be checked again after three weeks time, such as discovering oil emulsion, check the mechanical seal, if necessary, to replace ( Contact our maintenance department) After, if there was change condition, replace the seal should be air tight test ( Air pressure to zero. 5kg/cm2) 。

stainless steel submersible pump maintenance

in order to guarantee the performance of the stainless steel multistage submersible pump in good condition, he shall make regular inspection and maintenance for the submersible electric pump ( 1 year 1) , and make the maintenance records.

1. Turn the stainless steel submersible pumps and proved by hand submersible electric pump rotation is flexible, check whether there is any loose or on submersible electric pump pipe and joint leakage phenomenon.

2. Check the bearing lubricating oil in the body, ensure the oil level in oil mark the center line of the place nearby, and depending on the situation in a timely manner to replace or supplement.

3. Check whether there is any breakage on submersible pump cable and reliable power supply, electric device, the power supply voltage, frequency, and nameplate, its deviation is within allowable limits prescribed by the conditions of use.

(4) after installation of stainless steel deep well submersible pump, points should be taken to start the motor, and proved the motor steering is correct. After each downtime and boot before, must determine the hot and cold insulation resistance, to observe the change of the insulation resistance.

5. Stainless steel submersible pump in the first months of work, working after 100 hours, lubricating oil should be changed, after 1000 hours of work with an oil change at a time. For filling water submersible pump still need regular replacement of upper and lower end cover, bearing indoor skeleton oil seal and lithium grease, in order to ensure good lubrication condition.

6 often adjust the packing gland, packing materials indoor water dripping of normal ( It is advisable to at 60 drops/min or so) 。

7) regularly check the wear condition of shaft sleeve, wear when there is a large, should be replaced in a timely manner.

end stainless steel submersible pump in winter season when using, parking, a drain at the bottom of the pump body screw must be turned on, and put the net medium, in order to prevent the pump body frost crack.

pet-name ruby submersible pump stopped for a long time, can't let it soak in water, the pump must be well is put forward, and then unwrapped all the pump body, dry the water. Rotating parts and junction are coated with grease packed, position interesting ( During winter storage temperature is not lower than - 5°c） , dry, free of chemical goods in good condition.
