Sumbersible pump circuit, sealing and insulation are checked

Shandong Hairui Zhonglian Pump Industry Co. , ltd. The sumbersible pump that is a major produces manufacturer. When type selecting of client sumbersible pump, manufacturer of my company water pump can provide the before-sales service such as price of sumbersible pump model, sumbersible pump, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is the knowledge that checks about sumbersible pump circuit, sealing and insulation:

The exterior circuit of 1. sumbersible pump checks:
When circuit of join sumbersible pump, should see power source signal first, close gate again next. As above water is slow and faint, should change wiring random two-phase receive; Be like when do not sail upstream or be being checked from water, Sumbersible pumpGive out moo moo sound and do not turn, should stop instantly machine. Is the order of the examination: ?
2. sealing checks:
The gap after mechanical and sealed box wears away is too big, if maintain not in time, soggy hind leakage of electricity brings about water electric conduction, puncture winding, causeSumbersible pumpBurn down. After general job 300h, will turn on the water unscrew of heal snail a place of strategic importance undertakes checking. The water that if give off,comes or water oily mixed liquor are little at 25mL, if exceed 25mL,water pump still can use; , should examine integral type grind in sealed box piece wear out condition. If grind an attaint, answer to be repaired to the manufacturer that has corresponding technology and facility. Normally barometer of usable pump series connection aerates, will examine the sealed case of pump, fill baric force to be 0.6kPa, continuously 10min, if pressure expresses a needle to be not moved, regard as sealed and good.
3. insulation circumstance checks:
If leakage of electricity of sumbersible pump itself, soggy hind can create leakage of electricity of wiring box alternate with and housing incessant predestined relationship. Because this answers to often check the insulation resistance of sumbersible pump, should be in 0.5 million Europe commonly above, under 0.5 million Europe, sumbersible pump must not be used.
Thank you to be mixed to the visit of above content very much read! This information is the introduction that checks about sumbersible pump circuit, sealing and insulation, if you still want to have farther knowledge to this problem, or want to buy this relevant product, contact personnel of my company customer service directly please, my company returns production to suck pump oneself, welcome you at any time seek advice.
