Note: if the user has special temperature, medium and other requirements, please specify the details of the delivery media in order to provide more reliable products.
- QW (WQ) submersible non clogging sewage pump product features:
QW (WQ) type submersible non clogging sewage pump adopts the unique leaf or double blade impeller structure, can greatly improve the ability of sewage through the submersible sewage pump, can be effective through the fibre material 5 times of pump pump diameter and sewage pump 50% of pump diameter of solid particles.
The QW (WQ) type submersible without tungsten carbide material clogging sewage pump mechanical seal decay using a new type of rigid, and double seal to improve sealing, the long run in the oil chamber, the submersible sewage pump safety more than 8000 hours of continuous operation.
The QW (WQ) type sewage pump compact structure, small volume, low noise, energy saving effect, convenient maintenance, no need of pump room, dive into the water to work, greatly reduce the project cost.
The QW (WQ) type submersible non clogging sewage pump seal oil chamber is provided with Water Leakage high-precision interference detection sensors, and embedded within the stator windings of the thermal components, the absolute protection of WQ submersible pump motor.
And according to user needs can be equipped with automatic safety protection control cabinet, the absolute protection of the submersible sewage pump Water Leakage, leakage, overload and over temperature, improve the safety and reliability of the product.
The float switch solution based on the required changes, automatic control of submersible sewage pump start and stop, without special care, it is very convenient to use.
The QW (WQ) type sewage pump according to user needs with double rail automatic coupling installation system, which brings great convenience to installation and maintenance, this may not enter the sewage pit.
It can be used in the whole range of lift, while the motor is not overloaded.
QW (WQ) type submersible non clogging sewage pump with two different installation methods, fixed automatic coupling installation system, mobile free installation system.
- QW (WQ) submersible non clogging sewage pump structure:
QW (WQ) type submersible non clogging sewage pump is composed of motor and pump is composed of two parts, the two separated by oil isolation chamber and mechanical seal components, belongs to electromechanical integration products, motor and pump combined with a shaft (rotor) of the pump short length, compact structure. Equipped with a variety of protective devices, so that the pump running safe and reliable. Its main components are as follows:
Signal line 1: equipped with a full range of water pump control cabinet, the pump to implement a full range of protection, including water leakage, broken phase, short circuit, overheating, motor overload, etc..
Motor stator 8: using B or F insulation.
Water leakage probe 11: the component is installed in the oil chamber, when the mechanical seal is damaged, water enters the oil chamber, the probe can send out the signal from the control system to pump the implementation of protection.
Mechanical seal 13: the use of two - way series seal, the selection of a new type of hard corrosion-resistant tungsten carbide material, with a reliable sealing, wear-resistant, long life and other characteristics.
Impeller 17: impeller using a single or double channel structure, with a strong ability to pass through large materials and fiber waste, reduce clogging, winding fault.
15: pump body and impeller matched with the pump with high efficiency.
Sealing ring 18: installed in the pump body mouth ring, when the impeller due to the operation of the mouth ring wear, can replace the sealing ring, to ensure that the best efficiency of the pump to run.
- QW (WQ) submersible non clogging sewage pump use method and the matters needing attention:
1.QW (WQ) - type submersible sewage pump before use should be carefully check whether the cable is damaged, fasteners are loose or fall off, the pump in the transport, storage, installation process, there is no deformation or damage.
2 the same and relative insulation resistance of the electric pump motor is measured with 500V MB, the value should be not less than 2 Mb, otherwise, the stator winding of the motor should be dried and the temperature of the drying process is not allowed to exceed 120.
3 the installation of the series of sewage pumps are fixed and mobile two. When using a fixed type automatic installation, the chain were put into (from the pump outlet, the connection should be parallel to the pump outlet) two screw rings or lifting plate on the lifting pump. Slowly slide down the slide until it is automatically coupled in place. When using the mobile installation, first put the hose, with chain wear into two rings under the lifting pump, attention can not be used as cut cable rope, in order to avoid danger.
4.QW (WQ) type submersible non clogging sewage pump connected to the direction of rotation after the rotation is counterclockwise from the water inlet, if the pump reverse, only the cableAny of the two wire line in the reversed connection position.
5.QW (WQ) type submersible non clogging sewage pump casing wire must be in strict accordance with the relevant regulations in order to ensure that when used properly connected, personal safety in electric pump operation, is strictly prohibited in the near installation, others do? ~ or move, just in case the pump leakage accident.
6.QW (WQ) type submersible non clogging sewage pump in the absence of special circumstances must be equipped with full automatic water pump control cabinet, do not hang directly or use the grid switch to connect the power supply, to ensure the normal operation of electric pump.
7 may not be in the long-term low lift pump condition (general use head shall not be less than the rated head of 60%), the best use can control the lift range in the proposed within, to prevent electric pumps due to overload and burn the motor.
8 no self circulation cooling device of the pump is strictly prohibited the overall long-term operation of the water, to prevent overheating of the pump damage
