ISW-type horizontal centrifugal main features, horizontal centrifugal pump running smoothly: the absolute concentricity pump shaft and impeller excellent static and dynamic balance to ensure the smooth running, no vibration. 2, a single-stage centrifugal pump leak: carbide seals of different materials, to ensure the transportation of different media leaks. , Horizontal centrifugal pump noise: the pump bearing support of the two low-noise, smooth operation, in addition to weak motor sound, almost no noise. The 4 horizontal centrifugal low failure rate: the structure is simple and reasonable, the key part of the world-class quality matching, the whole time between failures greatly improve. Convenient, horizontal centrifugal pump maintenance: Replace the seals, bearings, easy and convenient. 6, horizontal centrifugal More space: exports to the left, right, up three directions, it piping installation, save space. ISW horizontal centrifugal pump purposes of 1, the ISW horizontal centrifugal pump for conveying water and physical and chemical properties similar to water or other liquids used, suitable for industrial and urban water supply and drainage, high-rise building pressurized water, garden irrigation fire boost long-distance transportation, HVAC refrigeration cycle, bathrooms, heating and water circulation booster and equipment for use temperature t ≤ 80 ℃. 2, ISWR horizontal type hot water pump widely applicable: metallurgy, chemical industry, textile, paper-making, as well as hotels and restaurants such as boilers, circulation of urban heating system iswr use temperature t ≤ 120 ° C. 3, ISWH stainless steel pipeline pumps for non-delivery of solid particles, corrosive, viscosity similar to water, apply to the petroleum, chemical, metallurgy, electricity, paper, food, pharmaceutical and synthetic fibers sector, the use of temperature to -20 ℃ ~ +120 ℃. Type HORIZONTAL ISWB oil pump, for the transport of gasoline, kerosene, diesel and other oil products, or flammable, explosive liquid transport medium temperature of -20 to +120 ° C. ISW horizontal centrifugal structure diagram four ISW horizontal centrifugal pump Model significance ISW horizontal centrifugal pump before starting to prepare: 1 test motor rotation is correct, the top of the motor to the pump to see Shun clockwise rotation, shorter test time, so as not to dry mechanical seal wear. 2, open the exhaust valve of the liquid fills the entire pump body, be full and close the exhaust valve. 3, check each part is normal. 4 hand plate moving the pump so that the lubricating fluid into the mechanical seal faces. 5, high-temperature should be preheated, the heating rate of 50 ° C / hour, to ensure ministries heated uniformly. Starter: 1, fully open the inlet valve. 2, close the discharge piping valves. 3, starter motor, observe the correct pump operation. 4, adjust the outlet valve opening to the required conditions, such as a user equipped with a flow meter or pressure gauge at the pump outlet, at the rated point of the performance parameters are listed in the table on the operation of the pump by adjusting the outlet valve opening, such as a user equipped with a flow meter or pressure gauge at the pump outlet, by adjusting the outlet valve opening, measuring the pump motor current, the motor rated current, otherwise it will cause the pump to the motor overload run (ie current run) burned. The tune just outlet valve open large small and plumbers conditions. 5, check the seal leaks, normal mechanical seal leakage should be less than 3 drops / min. 6, check the motor bearings at temperature rise ≤ 70 ℃. Parking: 1, high temperature before cooling, the cooling rate of <10 ° C / min, the temperature is reduced to below 80 ℃ to parking. 2, close the discharge piping valves. 3, stop the motor. 4, close the inlet valve. 5, such as long-term parking, the liquid in the pump should be exhausted.
