Product Overview
The HWQ(D) series sewage and sludge submersible electric pump (hereinafter referred to as the electric pump) consists of three parts: a water pump, a seal, and a motor. The motor is located at the top of the electric pump and is a single-phase or three-phase asynchronous motor. The water pump is located below the motor and features a double-flow non-clogging impeller and volute structure. A double-end face mechanical seal and a skeleton oil seal are used between the water pump and the motor. The mechanical seal acts as a dynamic seal, and each fixed mouth seal uses an oil-resistant rubber "O" ring for static sealing to ensure reliable pump sealing. The electric pump shaft uses a stainless steel welded shaft to ensure reliable mechanical strength, improve shaft wear resistance and corrosion resistance, and facilitate impeller disassembly and assembly during maintenance. This series of pumps has the characteristics of anti-winding and non-clogging, and has unique functions in conveying mixed liquids containing solid particles and long fibers.
Applications
This series of electric pumps are widely used in: a. Pumping sewage containing solid particles such as short fibers, paper scraps, and sand; b. Pumping sewage containing mud, gray water, domestic sewage, fecal urine, and other soft solid substances; c. Drainage systems of urban sewage treatment plants, municipal projects, construction sites, agricultural irrigation and drainage, pond dredging, etc.; d. Chemical, petroleum, pharmaceutical, papermaking, and cement plants (not suitable for occasions with explosion-proof, strong acid, and strong alkali requirements).
Features
● All-copper motor and cold-rolled silicon steel sheet: high efficiency, low temperature rise, not easy to burn out;
● High-frequency quenching treatment of shaft material: Improves shaft wear resistance and corrosion resistance, and facilitates impeller maintenance;
● Motor with thermal protector: Prevents motor burnout during abnormal operation such as overload and jamming;
● Mechanical seal structure with stationary ring pressure plate: Ensures the sealing of the pump end stationary ring;
● High head, large flow;
● Anti-sand structure design of impeller: Prevents solid particles in the medium from entering the mechanical seal, reducing mechanical seal wear, and extending service life.
Operating Conditions
● Medium temperature not exceeding +40℃;
● Medium PH value of 4-10;
● Solid particle concentration in the medium does not exceed 3%;
● Maximum submergence depth of the water pump does not exceed 5m
● Conveying medium density ≤1.3x103kg/m³;
● Power frequency is 50Hz, voltage is single-phase AC 220V, three-phase AC 380V, voltage fluctuation range is ±10% of the rated value.
