Application field, overview

Submersible pump is a new water pumping machinery, machine and by diving submersible pump components. It is widely adapted to agricultural irrigation, urban and rural living areas, industrial and mining drainage and construction rainfall and rivers, reservoirs, fountains, refrigeration cooling systems, thermal baths and other water conservancy facilities. Its main feature is motor, water pump into the water work together as one, use, easy maintenance, high efficiency, safe and reliable operation.

Use conditions

1) Power: 380v three-phase AC, 50HZ.

2) Water quality: a) the temperature of water is below 20 (high temperature resistance 80)

b) The solid content is less than 0.01%. (According to the quality)

c) PH 6.5-8.5

d) The content of hydrogen sulfide is less than 1.15mg/l

e) The concentration of chlorides is less than 400mg/l

3) The inner part of the diving electric pump must be full of clean water and diving electric pump must safely submerge to wok.

4) Mounting depth shall not exceed 20% of water pump rated head and well face must be smooth and straight.

Cause and exclusion

Symptom	Cause	Remedy
No water or less water or intermittent water	1. Motor does not start (such as low voltage wires too small for too long, the voltage drop is too big or stuck pump does not work) 2. Pipes get clogged or blocked filter 3. Pipeline rupture, pipeline damage of rubber gasket 4. Suction mouth out of the water 5. Instead submersible pump steering 6. Impeller mouth ring and seal wear	1. Exclusion circuit failure to identify and eliminate the cause of the out of working 2. Clear blockage 3. Repair breakage, replacement pads 4. Submersible pump down, if it does not water, it may be more than a submersible pump head range, it is recommended to change the pump. 5. Replace the impeller, the seal ring
Overcurrent or pointer swing	1. Current, low head beyond the scope of use, motor overload 2.Motor graphite bearing wear, water pump bearing or bushing wear rubber 3. Thrust bearing wear, under the impeller 4. Bearing bending, bearing different circle	1. Adjust the valves, reducing flow 2. Replace with new bearings or shaft sleeve 3. Replace the thrust shaft and thrust plate 4. Bending to send factory overhaul, replacement bearings
Motor winding insulation resistance geothermal below0.5MΩ	1. Aging or damaged wire insulation 2. Rubber cable breakage 3. Gland failure	1. Open winding wrapped with tape breakage or rewind new coil. 2. Find breakage, fire or wrapped with tape damage. 3. Open, connected, redressed.
Motor can't be restarted and buzzing.	1. Broken wires or switches off (single-phase operation) 2. Motor guide bearing is not working 3. The impeller and the pump body jammed foreign body in it 4. Low voltage	1. Repair broken, connect to fuse 2. Repair or replacement of bearings 3. Remove foreign bodies 4. Adjust the voltage
Severe vibration motor	1. Motor rotor is unbalanced. 2. Impeller is unbalanced 3. Bearing bending 4.Bearing wear	1. Rotor balance 2. Impeller balance 3. Bearing straightening 4. Replacement of bearings, bushings
Motor windings burned	1.The motor is shortage of water 2.Single-phase operation 3.Long time overload running	1. Attention, it must be filled with water 2. Check and adjust the start to ensure the protection of equipment so that the motor running. 3. Reduce the load so that the current, voltage can't exceed the rated values on the nameplate.
