Shanghai KaiQuan WQ/E Small Submersible Sewage Pump, Centrifugal Pump, Fire Boosting Pump, Compact Size

WQ/E Small Submersible Pump Features:

One, selected pump bodies and impellersThe design is repeatedly modified using CAD technology, ensuring a better fit between the pump body and impeller, and making it easy for fibers and debris to pass through.Non-tangling or blocking. The impeller is strictly balanced, resulting in minimal vibration and smooth operation.

Section 2: High-reliability Diving MotorSpecially designed and manufactured diving motor, with an IP68 protection rating, stator winding with F-grade insulation, suitable for submerged operationExcellent cooling performance, low actual temperature rise in the winding, resulting in a more durable motor.The motor is cooled through the casing. The medium only needs to submerge half the height of the motor stator to ensure reliable and safe operation. SubmergeThe more, the better for the motor's cooling.The cable is a heavy-duty rubber sheathed flexible cable with water-resistant properties. The wire core cross-section is selected for continuous full-load operation at an ambient temperature of 40°C.Used, very reliable. The cables are double-secured on the handle to prevent damage during transportation, installation, and use.

Three: The motors feature tight sealing and strict inspection.

1. Axle SealTwo independent single-end face mechanical seals are respectively arranged on the pump and motor sides, forming two shaft seals, with leakage amounts merelyBelow one-tenth for double-face mechanical seals. The lubricating oil inside the oil chamber lubricates and cools the friction pair on the motor side seal.However. The pump side mechanical seal contacting the medium uses silicon carbide/silicon carbide "hard-on-hard" friction pairs, which have high hardness and low friction coefficient.Low failure rate, not easy to wear out; mechanical seal on the motor side, fully immersed in oil, utilizes "soft-on-hard" graphite/silicon carbide.Friction parts with low friction coefficients and easy to "wear in," ensuring reliable sealing. The smaller gap between the impeller and the pump cover.The gap can prevent impurities from entering the shaft seal chamber while maintaining optimal working conditions for the mechanical seal. The rubber components of the mechanical seal are made of...The material is oil-resistant nitrile rubber, while the springs and other structural components are made of stainless steel.

2. Full-sealed cableWQ/E pump motor cable wires are equipped with a full-sealed structure featuring cast heads, with the cable sheath, wire cores, and cast heads being vulcanized together.One whole assembly ensures water does not enter the motor cavity through the cable sheath or gaps between the wire cores. But the cable ends cannotContact with water, as water entering the cable will inevitably lead to a significant decrease in the cable's insulation resistance, thereby affecting safety.

3. Sealing between partsThe connection and mating surfaces of various parts are sealed with O-rings for reliable static sealing.

4. Sealing Integrity TestAll parts must pass pressure testing before assembly. Each pump undergoes strict inspections during and after assembly.Pressure test in "G" gauge to ensure the motor's sealing.

Section 4: Reliable Bearing ConfigurationChoose high-quality brand-name deep groove ball bearings, which all have ample load margin, ensuring reliable operation of the products.

FiveJet mixing functionHoles for jet mixing are drilled in the pump housing. As the pump operates, high-pressure water inside the pump passes through the jet holes to form a high-speed jet stream.Aggressively stir to suspend impurities over a wider area, which are then pumped out and removed, thus ensuring cleanliness over a larger scale.It forms sediments, offering an advantage over mere mechanical stirring at the pump suction inlet.
