Specifications

7.5kw water pump for agricultural irrigation 380V

1. Working Parameters:

(1). Flow range10~600m3/h,

(2). Lift scope within 5~600m;

(3). Caliber scope 32~203mm,

(4). Temperature range-15~80° C.

2. Products Overview:

  SQJ Series submersible pumps widely used in farmland irrigation, spray irrigation and water-use, industrial and civil

buildings, also the drainage system to level hills, mountains of diversion, in the low-lying areas dunes, urban and rural

mining supply, drainage and other water conservancy facilities. Its characteristics are the electrical, water pumps and

assembled into a simple structure, the installation of the demolition of convenience, small footprint, the use of simple maintenance, safe reliable operation, no water pollution and so on.

3. Use conditions:

(1). 380 V bias voltage does not exceed + -5% and 50 HZ frequency, and the deviation is not more than + -1% of the

      three-phase power supply.

(2). Electrical cavity must fill water.

(3). The first-class pump impeller should at least go into the dynamic water level 2 m below surface. Static pump unit

      immersed under water shall not be greater than 70 m.

(4). Electrical from the bottom of the bottom of the well shall be not less than 3 m.

(5). The water temperature no higher than 20 ° C, QJR-temperature hot water pump up to 80 ° C.

(6). Water and sand content (by mass) of not more than 0.01%.

(7). Water PH 6.5-8.5.

(8). The hydrogen sulfide in water content is not more than 1.5 mg / L.

(9). Water should ensure continued operation of the pump needs.

4.Structure feature:

(1). pump: The pump is installed on the upper part of the pump units.It's centrifugal and has water lubricated

a. bearing mounted with the motor shaft by a joint.

b. There is a check valve on top of the pump which could prevent rapaid inverse rotation from backword flow.

c. The pump unit should be immersed below the dynamic water lever when in using.

(2). motor: The motor is installed under the pump.

a. It is a water filled in hermatical structure.The stator windings are water-tight and PE insulating and multi-layers are covered with nylon.

b. The motor bearing is water-lubricated.The inner motor contains clean water to cool the water body and the bearing.

c. The rubber diaphgram adjusts the pressure change caused when temperature rises.

d. There is a sand resistance system in the upper part of the motor.
