Submersible sewage pump has been more and more people's attention, the use of a 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 you to several energy-saving non-clogging sewage pump, from Shanghai Roland Fluid Control Co., Ltd. sewage pumping point Details: 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. Second, from Guangzhou City, the first pump factory sewage pump Typical uses: · The discharge of wastewater with solid particles, urban sewage · Farmland irrigation · Construction Pump Features: · Good sewage : Impeller with single and double channel, anti-clogging, anti-winding, can effectively pass the solid particles below 100mm in diameter · Easy installation: automatic coupling installation and mobile installation · Convenient control: automatic control, protection and signal output, easy to concentrate Monitoring · High reliability: with leak detection, overheating, overload protection and other functions · Saving money: Use this system to save a lot of civil construction investment 40 ~ 60%, saving operation and management costs 30 ~ 40% Structure Description: · Power in the pump above 30kW , The wiring cavity is provided with a water leak detection probe, when inadvertently causing the wiring chamber water, the probe sends a signal, the control system to implement pump protection · Stator insulation class F (155 ℃), built-in thermal overload protection · Power at 18.5 Above kW, each pump is equipped with an automatic cooling system and the liquid that is forced out by the impeller is small Diverting into the outer 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 · The lower end of the motor is equipped with a water leak detector which sends a signal when the mechanical seal on the motor side fails or causes water infiltration. Pump protection · Specially designed two single-end seals (already reported national patent), to ensure reliable and safe pump operation · 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, By the control system shows that the management told the timely manner, while the control system to closely monitor the leakage conditions · Impeller unique design, with large flow through the large materials and fiber waste can reduce clogging, winding failure · Pump Replaceable wear ring between the impeller and the pump to ensure optimal operation of the pump Model Description: 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 the liquid to be pumped: 5 ~ 9 · Motor cooling: Water pump below 18.5kW is cooled by external medium, water pump with 18.5kW or above is used for internal water circulation cooling · Start-up mode: 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 pumps, : WQG submersible sewage pump PW sewage pump YWd efficient non-clogging submerged pump ZQG submersible axial pump QXG submersible water pump PWF-type corrosion-resistant sewage pump ZPW self-priming non-clogging pump Third, from Shanghai Rui trillion to Drainage Equipment Co., Ltd. Submersible Sewage Pump Details: This series of non-clogging sewage pump is the introduction of foreign high efficiency energy-saving non-clogging sewage pump, the organization developed from the technical strength of the units, the performance standards have reached or exceeded the similar products at home and abroad, Due to the unique single-channel impeller, the dynamic seal adopts two sets of carbide mechanical seal with special materials, the motor is separated by the oil chamber, , Durable, accurate line, the use of repair convenient, high efficiency, significant energy saving, is the latest pump replacement products, welcomed by users. The pump has a variety of models and different structures available for selection.
