Product overview

1., the German LOCKE LKWQ Series stainless steel submersible sewage pump adopts the design of large flow blockage resistant hydraulic components, greatly improving the ability of passing through dirt. It can effectively pass 5 times of the fiber diameter of the pump caliber and the solid particles with diameter of about 50% of the pump diameter.

2. the design is reasonable, the matching motor is reasonable, the efficiency is high, and the energy saving effect is remarkable.

3., the mechanical seal adopts two way series seal. The material is hard and wear-resistant tungsten carbide. It has the characteristics of durable and wearable. It can make the pump run safely and continuously for more than 8000 hours.

The 4. pump has compact structure, small volume, convenient movement and easy installation. It does not need to build a pump room. It can work in the water and greatly reduce the cost of the project.

5. pump oil room with oil and water probe, when the pump side mechanical seal damage, water into the oil chamber, the probe signal, the implementation of the pump protection.

6., according to the needs of users, the automatic safety protection control cabinet is equipped to monitor the leakage, leakage, overload and over temperature of the pump, so as to ensure the reliable and safe operation of the pump.

7. double track automatic coupling installation system, the installation of the pump installation, maintenance has brought great convenience, people can not have to import and export pit for this.

The 8. float switch can be changed according to the required water level. Automatic control of the pump to stop, without a special person to watch.

9. in the use of the lift range to ensure that the motor operation is not overloaded.

10. according to the use of the machine, the motor can use the water jacket outside third circulating cooling system, which can ensure the safe operation of the electric pump in the dry (dry) state.

11. installation methods are fixed automatic coupling installation and mobile free installation of two kinds, can meet the different use of the situation.

 

Product advantage

 

The LKWQ Series stainless steel submersible sewage pump is made up of two parts, the motor and the pump. The two are separated by the oil isolation chamber and the mechanical seal component. They belong to the electromechanical integration product. The motor and pump share the same shaft (rotor), and the whole pump has short length and compact structure. A variety of protective devices are equipped to make the pump run reliable. The main components are as follows:

Signal line: equipped with full water pump control cabinet to carry out all directional protection to the pump, including water leakage, fault phase, short circuit, overheating, motor overload and so on.

Motor stator: use B class or F grade insulation.

Water leakage probe: this component is installed in the oil chamber. When the mechanical seal is damaged, the water enters the oil chamber. The probe can send out signal to protect the pump by the control system.

Mechanical seal: double channel series seal is adopted, a new type of hard corrosion resistant tungsten carbide material is selected. It has the characteristics of reliable sealing, wear-resisting and long life.

Impeller: impeller adopts single channel or double way structure. It has strong passing capacity and can reduce blockage and winding faults through large materials and fiber waste.

Pump body: with the impeller, so that the pump has high efficiency.

Sealing ring: installed in the ring of the pump body, when the impeller is running, the wear of the ring can be worn, and the seal ring can be replaced to ensure the best efficiency of the pump.
