Clear water pump overview
Ordinary water pumps are designed for maximum efficiency, that is to say the water pump's hydraulic structure parameters are the best combination for maximum efficiency. For other pumps, such pumps with special requirements can not exceed the efficiency of the same period of the pump. Other pump efficiency is lower than the main reason for the water pump is their over-flow channel widened. The decrease in efficiency is mainly related to the degree of broadening. Other pump runners are widened to prevent clogging. IS, IH-type water pump for the transport of water or other physical and chemical properties similar to water, the temperature is not higher than 80 ℃. Main purposes: Suitable for industrial and urban water supply, drainage, irrigation and drainage can also be used for agriculture. The design of the pump selection of excellent domestic hydraulic model, using IS centrifugal pump performance parameters, based on the general vertical pump designed to be clever combination, at the same time based on the use of temperature, medium, etc. derived in the ALG-based For hot water, high temperature corrosion-resistant chemical pumps, pumps. The series of products with high efficiency, low noise, reliable performance, etc., in line with the latest national Ministry of Machinery JB / T53058-93 standards, products according to the international ISO2858 standard design and manufacturing. For conveying water and physical and chemical properties similar to other liquids used in water, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden sprinkler, fire pressurization, long distance transmission, HVAC refrigeration cycle, bathroom and other hot and cold water circulation Pressurization and equipment support, the use of temperature T <80 ℃. Hot water pump for metallurgy, chemicals, textiles, wood processing, paper and restaurants, bathrooms, hotels and other high-temperature hot water booster circulating transport and urban heating cycle pump, the use of temperature below 120 ℃. High temperature water pump is widely used: energy, metallurgy, chemicals, textiles, paper and restaurants, bathrooms, hotels boilers and other high-temperature hot water circulation pump circulation and urban housing heating circulation pump, the use of temperature below 240 ℃. First, the orchard single-phase water pump is divided into self-priming pumps, water-filled pumps and submersible pumps, the selection principle is: Self-priming clear water pump: water quality is relatively fixed working position, suction pipe within 3.5 meters of stable, Used in the well water supply, orchard irrigation can reduce the water when the pump trouble, the actual head of less than 22 meters, less efficient chemical pump. The first time put into operation should first join the circulating emptying water, the pump to complete self-absorption. Water-filled clear water pump: good water quality and good mobility of the pipeline is relatively not fixed, suction 2.5 meters within the actual lift of 32 meters, the pump flow can be adjusted as needed, to adapt to species of professional households for spraying, water supply, high efficiency . Suction pipe should ensure good sealing. Submersible clear water pump: adequate water head low, the valve is suitable for irrigation of large amounts of water in orchard farmland. Submersible pump into the water because of the work of the axial push water increased, reducing the amount of water will increase the pump load. So do not install the submersible pump outlet valve to prevent the valve is turned off because the pump resistance is too large resistance to burn the motor. Second, the use of clean water pump should pay attention to voltage matching and safety of electricity, because the water pump is working in wet conditions, the power switch should be installed before the leakage protection switch. Do not move the pump work, suction pipe bottom valve vertically into the water 0.4 meters, poor water quality should be set filters to prevent debris sucked into the pump to affect the pump operation. Third, the water pump is connected with the motor and the pump as a whole, the motor rotor fulcrum bearings and pump bearings, a rigid power transmission to the pump impeller rotary valve. Only between the pump impeller and the vortex shell 0.10-0.22 mm gap, debris grit easily stuck impeller, the motor rotor can not rotate and failure. From the repair pump failure analysis due to the impeller stuck motor damage accounted for more than Bacheng. When turning off the power switch, if the motor does not turn on, turn off the power in time, and the motor will generate a rotating magnetic field by the inductor. The motor will not be damaged in a short time. You can use a screwdriver to remove the motor cover, rotate the fan left and right hand until the flexible back cover and then power.
