Submersible sewage pump has been more and more people's attention, the use of more and more wide range, from the original purely for the transport of fresh water to the present can transport a variety of domestic sewage, industrial wastewater, construction sites drainage, liquid feed, etc. Wait. In municipal engineering, industry, hospitals, buildings, restaurants, water conservancy construction plays a very important role in all walks of life. But everything is divided into two, the most critical issue for the submersible sewage pump is the reliability issue, because the submersible sewage pump is used under the liquid occasion; the medium is mixed with a mixture of solids containing liquid; Pump and motor close; pump is vertical layout, the weight of rotating parts and impeller pressure in the same direction. Here I introduce several energy-saving non-clogging sewage pump First, from Shanghai Roland Fluid Control Co., Ltd. Sewage pump point Detailed description: WQ submersible sewage pump main components from the impeller, pump body, base submersible motor. Pump and motor are the same shaft, because the pump is located at the bottom of the entire sewage pump, it can maximize the suction area of ​​the remaining sewage. Impeller for the double flow channel design, greatly improved the ability of dirt flow, can effectively pass the diameter of the pump diameter of 50% of the solid particles. Product implementation Q / TBJW2-2003 "sewage sludge submersible pump" standard.

A small part of the liquid pressed by the impeller flows into the periphery of the stator chamber for cooling to ensure the normal cooling of the motor when the water pump works at the lowest water level. Equipped with water leak detector, when the motor side mechanical seal failure or other causes water, the probe sends a signal, the control system to pump protection · Specially designed two single-end seal (already reported national patent), to ensure reliable pump operation Safety · Oil isolation chamber with oil-water probe, when the pump-side mechanical seal failure, water penetration into the oil chamber, the probe sends a signal from the control system to inform the management of timely processing, while the control system to closely monitor the leakage situation · Impeller unique design, with a large flow channel, through the large materials and fiber waste, Less clogged with replaceable wear ring between the wound and the pump impeller and pump failure, to ensure the pump is operated at optimum efficiency Model Description: Take WQG60-13-4 as an example · WQG - Submersible sewage pump · 60 - Flow rate (m3 / h) · 13 - Head (m) · 4 - Motor Power (kW) Performance parameters: · Discharge diameter: 40 ~ 600mm · Flow: 10 ~ 3750m3 / h · Head: 7 ~ 40m · Speed: 740 ~ 2840r / min * PH value of fluid to be pumped: 5 ~ 9 · Motor cooling: water pump below 18.5kW for external medium cooling, water pump above 18.5kW for internal water cycle cooling · Starting method: direct start and SCR soft start two kinds, the average number of 15 times / hour · Power Supply: Voltage 380V, frequency 50Hz Power: 1.5 ~ 250kW Water temperature: ≤ 60 ℃ More sewage pump, non-clogging pump series: WQG submersible sewage pump PW sewage pump YWd efficient non-blocking submerged pump ZQG submersible axial pump QXG submersible water pump PWF corrosion-resistant sewage pump ZPW self-priming non-clogging pump Third, from Shanghai Run-trillion to drainage Equipment Co., Ltd. Submersible sewage pump Detailed description: The series of non-clogging sewage pump is the introduction of foreign energy-efficient non-clogging sewage pump, the organization developed from the technical strength of the performance standards have reached or exceeded the same product technology at home and abroad, due to the unique single-channel impeller, dynamic seal The use of two sets of special materials, carbide mechanical seal, motor oil compartment separated, with no clogging, durable, accurate line, the use of repair convenience, high efficiency, significant energy saving, is the latest pump replacement in China , Welcomed by users. The pump has a variety of models and different structures available for selection.
