Flow Range: 8-2600m3 / h Head Range: 7-60m Operating Temperature: -15 ℃ -60 ℃ Supporting Power: 0.75-280KW Working Pressure: ≤1.6MPa Overcurrent Material: Cast Iron, Stainless Steel Product Overview: WQ Non-blocking submersible sewage pump is based on the introduction of foreign advanced technology, combined with the use of domestic pumps and the successful development of a new generation of pump products, with significant energy saving, anti-winding, non-clogging, automatic installation and automatic control and so on. In the delivery of solid particles and long fiber garbage, has a unique effect. The series pumps feature a unique impeller structure and a new machine seal that effectively delivers media containing solids and long fibers. Impeller compared with the traditional impeller, the pump impeller single or dual flow channel form, which is similar to a section of the same size elbow, has a very good overcurrent, with a reasonable volute, making the pump has more High efficiency, impeller static and dynamic balance test, the pump in the operation without vibration. The pump hydraulic performance of advanced and mature, the product tested by the performance indicators have reached the relevant standards, products on the market with its unique effect, reliable performance, stable quality by the majority of users of the welcome and praise. Structure Description: QW non-clogging submersible sewage pump consists of motor and pump composed of two parts, the two separated by oil isolation chamber and mechanical seal components, is a mechatronic products, motor and pump the same shaft (rotor) short pump length Compact structure. Equipped with a variety of protection devices, making the pump reliable operation, the main components of the role as follows: Signal Line 1: Equipped with full water pump control cabinet, the pump full protection, including water leakage, phase failure, short circuit, overheating, motor overload and other projects. Motor Stator 8: Class B or Class F insulation. Water Leak Probe 11: This element is installed in the oil chamber. When the mechanical seal is damaged, water enters the oil chamber and the probe sends a signal to protect the pump by the control system. Mechanical seal 13: The use of double-channel series seal, the selection of new hard anti-corrosion tungsten carbide material, with a sealed reliable, wear-resistant, long life and other characteristics. Impeller 17: The impeller adopts single-flow or double-flow structure. It has strong ability to pass large materials and fiber waste to reduce clogging and winding failure. Pump body 15: Used with impeller, making the pump highly efficient. Sealing ring 18: installed in the pump ring mouth, when the impeller due to the operation of the mouth rings wear, replace the seal ring, to ensure the pump to run at optimum efficiency. Features: 1. Adopting the anti-clogging hydraulic component design of the large flow channel, greatly improving the dirt passing capacity, effectively passing 5 times of fiber diameter of the pump diameter and solid particles with a diameter of about 50% of the pump diameter. 2. Reasonable design, matching motor reasonable, high efficiency, energy-saving effect is significant. 3. Mechanical seal with double-channel series seal, made of hard wear-resistant tungsten carbide, durable, wear-resistant and so on, can make the pump safe and continuous operation of more than 800 hours. 4. Pump structure is compact, small size, easy to move, easy to install, no need to build pump room, dive into the water to work, greatly reducing project costs. 5. Pump oil chamber with oil-water probe, when the pump-side mechanical seal damage, the water into the oil chamber, the probe signal, the pump protection. 6. According to user needs with automatic safety control cabinet, the pump leakage, leakage, overload and over-temperature monitoring, to ensure reliable and safe pump operation. 7. Dual-rail automatic coupling installation system to the installation of the pump installation and maintenance has brought great convenience, people do not have to enter the sewage pit for this purpose. Float switch can change according to the required water level. Automatic control of the pump stop, no need for special care. 9. In the use of lift to ensure that the motor is not overloaded. 10. According to the occasion of use, the motor can adopt the water jacket external third-party circulating cooling system, which can ensure the pump to run safely in the dry (dry) state. 11. Installation There are two kinds of fixed automatic coupling installation and mobile free installation to meet different use occasions. Usage: 1, the factory business seriously polluted wastewater discharge. 2, urban sewage treatment plant drainage system. 3, residential sewage drainage station. 4, air defense system drainage station. 5, hospitals, hotels, sewage discharge. 6, municipal engineering, construction sites. 7, exploration, mining auxiliary machine. 8, rural digester farmland irrigation. 9, water plant water supply device.
