Structure explanation of WQ series pump
Pump and impeller
It's repeatedly modified, calculated and designed by adopting the CAD technologies with reference to the latest hydraulic models, so that the pump body and the impeller are excellently matched, the flow channel i the widest, the sewage discharge capacity is the perfect and the equilibrium test of the impeller is strictly performed, therefore the vibration is reduced to the minimum and maximally lengthens the service life of the bearing and the mechanical seals.
Electric motor
The specially designed and manufactured submerged electric motor and the stator winding of the motor are Grade Finsulation. The upper limit working temperature of the insulation materials is 130 degree. In addition, the winding is connected with over-temperature protection components and protection will be exercised the on the electric motor by the electric controlled cabinet.
Cooling of the electric motor
When the power of the motor is over 18. 5kw, the inside of the pump could be installed with cooling system for the motor. Part of the liquid pressed out of the impeller flows into the periphery of the stator chamber for cooling, which guarantees the normal cooling of the electric motor when the water pump works at the lowest water level.
Mechanical seal
The mechanical seal is made by the famous manufacturers, selecting the durable friction materials low in friction index;the rubber piece is the oil proof butyronitrile rubber and the metal piece is the stainless steel. Under normal conditions, the product could operate without failure for over 8, 000 hours.
Bearings
The upper bearing is the deep groove ball bearing, to support the radial action force;the lower bearing is to support the radial and axial action forces;the selection of angular contact ball bearing could fully satisfy the effect to remove the axial action force. The imported or domestic noted brands of the bearings are used and it's not subject to damage in the service period of the pump. Sealing of the cable and electric motors.
Airproof of cable and motor
The cable selects the heavy rubber coating soft cable resisting the sewage and its mechanical intensity, oil resistance, cable lead section and current carrying competence of the cable are selected on the basis of 40 degree(not on the regular basis of 25 degree) under long term service period. Therefore, under normal condition, the current carrying competence of the cable has sufficient margin and longer service life. The gland bush compresses the lock ring of the cable tofix it. The cable adopts the color sign and digital sign, to make it easier for identification and connection of the cables. There is no earthing sign within the connection cavity and in the electric control cabinet and the earthing fastener and cable are strictly grounded, being safe and reliable. In the assembly process, the O-shape circle, cable seal and mechanical seal of each pump shall be strictly tested to ensure the reliable sealofthe cavity of the electric motor, including the connection cavity.
Oil chamber
In adition to lubricating the mechanical seals, the oil in the chamber could also take off the heat of the bearing. The oil chamber is also attached with the security function for liquid penetration. The water leakage probe could be installed in the oil chamber as the water penetrating to the oil chamber from the side of pump reaches certain density, the leakage probe will give alert to stop the pump by electric control cabinet and inform the operator to change the oil or maintain the mechanical seal.
Explanation of the protective devices
The overheating protection component is the electric apparatus controlled by temperature and embedded in the stator winding of the electric motor. Under abnormal operation status, when the winding temperature value reaches the set value of the overheating protection component, itwill urn on the indication light and automaticallystop the motor. Then it willinform the operator to check and find out the reason of the overheating. When the winding temperature decreases, the motor will recover to starting-up status.
(1)Protection device
The pump with the power less than 7. 5kw could be set with motor winding overheating protection component and water leakage probe;the pump with the power over 11kw could be set with motor winding overheating protection component, floater switch, and water leakage probe;the protection device functions only connected with the special electric control cabinet for submersible sewage pump. Though the electric control cabinet for submersible sewage pump of our company is optional for supply, for the safe and reliable operation of your pump, particularly for the prevention of burning motor it's the wise choice for you to choose our protection device. When the user has their own electric control cabinet, in case of the electric technical problems, particularly in protection devices, please contact our electric control cabinet professional group of our company.
(2)Water leakage probe
The water leakage probe serves to inspect the leakage of water. The two poles at one end of the probe are mutually insulated and have certain space;the lead of the pole is connected to the electric control cabinet by the cable. When the water penetrating to the oil chamber from the side of pump reaches certain density, or the connection cavity of the electric motor is slightly fed with water, the two poles of the probe will be connected, give alert to stop the pump by electric control cabinet(indicating light on) and inform the operator to change the oil or maintain the mechanical seal. When the connection cavity is fed with water, the alert will stop the pump to prevent the short circuit and inform the personnel to immediately adopt the maintenance measures.
(3)Floater switch
The floater switch serves to inspect whether the mechanical seal at the side of the motor is valid, whether the motor cavity is fed with water. The switch is installed underneath the motor cavity and the hollow cavity besides the bearing. The hollow cavity has holes to be connected with the bearing as when the mechanical seal at the side of the motor is invalid, the oil or water in the oil chamber will enter the cavity through the bearing chamber. The floaters will float off, give alert to stop the pump by electric control cabinet (indicating light on)and inform the operator to inspect the pump.
