QW series submersible sewage pump is mainly used in municipal engineering, and industry and agriculture, hospitals, building, hotel, restaurant, etc. Used for solid and various kinds of long fiber conveyor belt of wastewater, sewage and rain, city life also include raw water transport, aquaculture, irrigation (match with special material, can be used to have certain corrosive medium occasions). The XingPu product design, high efficiency, and the winding, no congestion, automatic coupling, high reliability, automatic control and automatic protection, and set the various states show protection device. The performance of the pump has a wide coverage: pump and motor shaft, of compact structure, convenient in maintenance; According to user requirements to provide special voltage pump type, the water level automatic control, and is equipped with automatic protection device and the control cabinet.
port type channel impeller, and has strong resistance to coil and non-clogged performance, through dynamic balance test, smooth operation. Oil lubrication and cooling seal, in which the motor and transmission media play a role. Between isolation In the volume of oil can slow down a rising pressure indoor. Separate sets of mechanical seal (depending on the structure of the pump and motor and make different), pump seal isolation; Up and down, provides double insurance series installation, improve the reliability. The rolling bearing, can bear all the axial and radial load, and completely and the conveying pump medium apart. Pump and motor coaxial, compact structure, shaft shortened from design, stretched out as far as possible reduce deflection, motion small vibration, seal and bearing life longer. High performance mouse cage type induction motor, especially for submersible pump design manufacture, accord with GB755 standards. Insulation class F, the highest working temperature level up to 135 ℃. The shell is made of motor in circulating cooling (22 KW above pump applicable). Diving sewage pump contains much way monitoring device, can protect the electrical leads to lead. Protection device: overload, phase lack, leakage, the humidity and temperature, the water immersion protection (as the pump structure and somewhat different commandingofficer).
This series of pumps out for 50 to 600 mm diameter, flow of seven to 6000 m3 / h, head for 5 ~ 60 M, power of 0.75 ~ 450 K, voltage for 380 V (also can be based on user needs: 660 V, 3 KV, 6 KV, 10 KV)

Conditions of use:

1, transport medium temperature not more than + 40 ℃;

2, transport medium PH value for four to ~ 10;

3, transmission medium solid content than the volume of below 2%;

4, voltage, 50 Hz ac 380 V 60 Hz ac voltage (or other according to contract manufacturing);

5, diving depth: 20 m; most

6, the lowest level: to top stator housing.

Notice: the order

1, indicate the accurate product model and product name, installation forms, performance parameters (capacity and head, motor power) and the use of voltage.

2, control cabinets should note the start-up mode (direct starting, since the lotus root step-down start, SCR soft start), liquid level control methods (float level, pressure transmitter digital display level), installation forms (indoor type, outdoor)

3, if need to match terminal box, should clearly indicate whether control type or pick up lines.

4, normal delivery length: 7.5 KW the following 6 M long water pump cable, the rest for 10 M, guide rail long for 3 M, if users have special requirements please to indicate.
