Stainless steel fountain pump is an important equipment to deep water lift. When used, the entire unit sneaked into the water work. The groundwater is extracted to the surface, is the life of water, mine rescue, industrial cooling, farmland irrigation, sea water lifting, ship loading, can also be used for fountain landscape, hot water stainless steel fountain pump for hot spring bath, but also for extraction from deep wells Groundwater, can also be used for rivers, reservoirs, canals and other water projects.
maintenance
1. Electrical aspects
(1) often check the submersible pump operating voltage and current. Three-phase voltage measured with a voltmeter should be basically the same, and in the 340 ~ 420V, measured with a clamp-type ammeter three-phase current should be basically the same, and 0.5 to 1 times the rated current.
(2) regular inspection submersible pump on the ground thermal insulation resistance. In the normal continuous operation 4 ~ 6h, the shutdown with a megger to measure the motor winding insulation resistance to the ground should be> 0.5M ?. For prolonged shutdown of the submersible pump, should also be used before the inspection.
(3) Before starting to check the thermal relay sensitivity and other protection devices work properly.
(4) Check the cable for damage. For oil-immersed submersible pump, pay attention to electric pump oil leakage on the cable insulation rubber damage.
2. Mechanical aspects
(1) often check the submersible pump mechanical seal. Open the oil hole screw, release a small amount of oil, such as oil containing water, then the grinding block (or the next block) sealed water leakage, should replace the sealed box and add new cooling oil. If the oil hole in the lack of oil or oil is not good, should be filled with oil (5 or 10 mechanical oil, sewing oil or transformer oil) or replace the new oil.
(2) the new or replacement of the grinding block of stainless steel fountain pump, after 50h should be used to open the water seal plug, check the oil (water) leakage, <5ml that seal normal, can continue to use> 5ml, the oil (Water) after drying tighten the sealing plug, continue to use after 50h for the second inspection, if still> 5m1, then the seal has a problem. For the use of submersible pump, the monthly leakage should be checked, should be <25ml, dry and then continue to use.
(3) Check the vibration of the pump motor synchronous speed is n0 = 3000r / min, 1500r / min, 1000r / min, 750r / min motor, the corresponding value of the corresponding vibration is δ ≤ 0.06mm, 0.1mm, 0.13mm, 0.16 Mm.
(4) regular inspection submersible pump bearing situation. See the bearing is short of oil, whether to run the inner ring or run the outer ring of the situation, the bearing is to be replaced (for water-filled electric pump bearings are best replaced once a year).
3. other aspects
(1) often check the submersible pump inlet screen whether the dirt is blocked by weeds, whether the impeller is wound.
(2) for a long time do not have the submersible pump, should be made of water, clean and dry, the upright on dry and ventilated indoor storage.
(3) submersible pump running 1 to 2 years after the motor core to check and clean. If the dirt, the motor can be immersed in 0.2% of the Haiou TX-10 or 105 detergent solution, heated to about 100 ℃ and stir the liquid to speed up the dirt dissolved, 1 ~ 2h dirt removed, then rinse with high pressure tap water A drop of water net, placed in the oven can be low-temperature drying.
