Stainless steel multistage submersible deep-well use should pay attention to what issues?

Stainless steel multistage submersible deep-well is shell adopts stainless steel submersible pump, widely used in water plant, hydropower station, maintenance, leakage) , coal-fired power plants ( Industrial, life, fire pump, etc. ) , steel mills, Scale pit water pump, etc. ) , agricultural irrigation, fire protection, municipal engineering, etc.

stainless steel multistage submersible deep-well operating conditions:

1, the sewage water pump series products in the rated voltage of 380 v, the power frequency 50 hz is

2, medium has more than 40 degrees Celsius temperature, medium density 1150 kg/m3, or less in PH 5 - 9 range between;

3, height is not more than 1000 meters above sea level;

4, medium viscosity is not super 1000 cp;

5, products work runtime must be completely into the water, but not more than 10 m diving depth;

stainless steel multistage submersible deep-well use note:

1. Well with submersible pump should be used in sand content lower than 0. 01% of clear water, pump room with embellish tank, capacity of water embellish shall meet a start.

      2. New clothes or after major repair of deep well pump, should adjust the clearance between the impeller and pump casing, impeller friction between housing and shall not be in the running.

      3. Deep well submersible pump before operation should be clear water bubbled into the shaft and bearing housing to embellish.

      4. Before starting the deep well submersible pump, check the project shall meet the following requirements: 1)

Base foundation bolt has tightened;

      2） Insurance axial clearance requirements, adjust the bolt nut has installed;

      3） Tighten and packing gland have been lubrication;

      4） Motor bearing has lubrication;

      5） Rotating motor rotor by hand and check out institutions are flexible and effective.

      5. Multi-stage submersible deep-well shall not be under the condition of no water idling. A water pump, secondary impeller should be immersed in water levels below 1 m. In the operation often should observe the change of water level in Wells.

      6. Operation, when found larger vibration based around, check the water water pump bearing wear or motor packing condition; When excessive wear and leakage, should replace a new one.

      7. Already contains mud pump suction and discharge, before the pump stop, clear water is rinsed clean.

      8. Stop before the pump, should first close the discharge valve, cut off the power and lock the switch box. When winter outage, should put clean water pump.
