Application of Submerged Pump in Sewage Treatment Project
First, the submersible pump performance and characteristics 1, QW series submersible sewage pump QW submersible sewage pump is based on market needs using a variety of high-tech development of a new generation of mechanical and electrical products used to transport containing dirt, solid particles, Fiber and other impurities liquid, widely used in metallurgy, mining, coal, electricity, chemicals, light industry, food and other industrial wastewater and urban sewage treatment, river, port dredge. The series of pumps have the following main features (1) The submersible sewage pump is vertical, the pump and the motor are coaxial, the impeller is a double-flow impeller, the flow passage is symmetrical, the balance is good, and the operation is smooth. According to the requirements of users, Spiral, swirling. (2) The degree of protection of the motor housing is IP68. (3) The submersible motor is dry or oil-immersed and connected to the pump. It is placed above the pump. When viewed from the inlet, the impeller rotates anticlockwise. (4) The stator core of the motor is made of high-quality silicon steel. The stator winding is F-class insulated. After the stator core is embedded, it is treated as a whole with a good overall electrical, mechanical, moisture-proof and good heat Stable performance. For high-power motor oil, water resistant wire, improve work reliability. (5) The pump impeller is installed on the shaft directly after the rigorous dynamic or static balance correction to ensure the pump runs smoothly and the vibration is small. (6) Bearings all use advanced bearings, oil lubrication and grease lubrication of two, the calculated life of the bearings are more than 15,000 hours, and the use of strict sealing measures to ensure the reliable operation of bearings. (7) The cable adopts advanced structure and sealing technology to prevent leakage and capillary leakage. The motor adopts an oil chamber and two series mechanical seals to connect with the pump. The material of the pair of mechanical seal pair depends on the medium and can be made of tungsten carbide Tungsten, silicon carbide / silicon carbide, silicon carbide / carbide, in order to ensure long-term safe and reliable motor seal, each motor factory after passing the inflatable inspection before leaving the factory. (8) The motor windings and bearings are equipped with over-temperature protection elements which, when the windings and bearings overheat, signal or shut off the power through the control system. Motor and oil room equipped with water detection device, once the water into the motor and the oil chamber, will send a signal to the police and cut off the power. (9) Submersible pump and all components immersed in water are anti-rust treatment or corrosion-resistant materials, pump all the bolts, screws, nuts, etc. are made of stainless steel, the impeller, the shell surface coating wear-resistant coating Layer, pump all steel parts are phosphating after surface cleaning, spraying epoxy polyester anti-corrosion paint, has good anti-rust properties, and does not pollute the water. (10) The motor cooling mode is divided into two types: motor oil-cooling circulation type and motor water jacket type water circulation type. a, motor oil-cooling cycle can be avoided when the motor is dehydrated running out of motor, you can make the suction level to a minimum, without the need for a separate cooling water system, is a very reliable cooling method. b, the water jacket outer cooling water circulation method, usually with the working medium for cooling water, the structure is simple, so it is also very easy to use and reliable. (11) The pump should be submerged in the pump impeller during operation, otherwise the motor may be burned or the overheat protector of the winding may be operated. In view of this possible unfavorable conditions, water level control should be installed. This series of pump parameter range: flow 20m3 / h ~ 7000m3 / h; lift 7m ~ 40m; motor power 1.5kW ~ 600 kW; voltage levels: 380V, 3000V, 6000V. Easy to install, the main fixed wet installation and mobile installation. 2, QWN series submersible pump QWN series submersible pump, suitable for a variety of water quality of the drainage works, the structure of the suction suction impeller, it has a compact, small size, can be made into multi-stage pump, lift up to 150 More than meters, stable work, simple operation, easy installation, small footprint, high pool utilization, high degree of standardization advantages. Widely used in metallurgy, municipal engineering sewage treatment, mining, chemical industry, paper making, agricultural irrigation and drainage, hospitals, buildings, railway stations, hydropower stations and other places. The series submersible pump has the following main features: (1) The pump is a vertical structure, reasonable design, compact structure, easy to open, easy maintenance. According to different parameters impeller can be designed for centrifugal, axial, Francis, cyclone, spiral, guide vane space guide vane structure for the use of built-in structure, so that the motor has a good cooling. (2) The motor matched with the pump is an oil-immersed water-resistant structure, and the motor is filled with insulating oil to increase the cooling effect. The motor windings are made of water-resistant and oil-resistant windings. Even if the water inside the motor does not drop in insulation, the failure rate of the units will be reduced to a minimum. The motor bearings adopt enhanced rolling bearings, thin oil lubrication, and windings overheat protection to keep the motor running When the winding temperature is too high to provide the signal. Dynamic sealing of the motor adopts hard to hard mechanical seal, good sealing performance and long unit life. This series of pump parameter range: flow 50 m3 / h ~ 2500 m3 / h; head 9 m ~ 150 m; motor power: 7.5 kW ~ 600 kW voltage level 380V, 3000V, 6000V. 3, QSKG series coaxial submersible pump coaxial submersible pump is the impeller of the pump installed directly on the motor shaft extension, pump one. Its features are compact structure, easy installation, no pump room, small footprint, can achieve long-distance control operation, safe, reliable, easy to maintain, the pump is short and thick. Available for mining (including surface mine) drainage emergency rescue, drainage surface drainage, urban water supply, irrigation and drainage with agriculture. The series submersible pump has the following characteristics: (1) system components: coaxial pump system consists of coaxial submersible motors, pumps, power cables, signal cables, connector materials, gate valves, check valves, elbows and other components. (2) submersible motor: water-filled wet seal structure, usually vertical installation. a, according to use, and some chassis with ribs and waterways, and equipped with suction hood to facilitate motor cooling. b, the bottom of the motor with flexible capsules, can automatically adjust, balance the pressure inside and outside the motor. c, the motor adopts mechanical seal and rubber oil seal, the interface with rubber "â—‹" ring and sealant, with good sealing performance. d, motor bearings and thrust bearings are made of high-quality high-strength wear-resistant materials, wear resistance, bearing axial force high. e, the motor windings directly connected by the lead cable and leads. & nbsp;
