KD series heating air conditioning circulating pump structure
First, the product overview KD series of heating air-conditioning circulating pump by the suction chamber, pressure chamber, impeller, pump cover, seal components, etc., motor and pump directly connected to the suction chamber and the pressure chamber separate, open the door structure, Dismantle the pipe. The pump has the advantages of novel structure, good interchangeability, high assembly precision, strong carrying capacity, convenient maintenance and stable operation. Its performance in line with GB / T5657-94 "centrifugal pump Technical Specifications Ⅲ" standard. Mainly used for air conditioning and refrigeration systems, hot and cold water circulation, high-rise buildings and residential heating heating boilers or heat exchanger cycle, thermal power plants, metallurgy, textile, brewing, sugar, chemicals, pharmaceuticals, waste heat utilization, water supply, irrigation, drainage Pumping station, power station, industrial water supply system, fire protection system, shipbuilding industry and so on. Features of KD Series Heating Circulation Pump II. Product Features 1.Efficient and energy-saving: CFD CFD is used to analyze and calculate the pressure distribution and velocity distribution in the pump, optimize the design of the pump flow passage, ensure that the pump has efficient hydraulic shape line , Improve the efficiency of the pump. 2, smooth operation, safe and reliable: direct connection between the motor and the pump, simplifying the intermediate transmission structure and enhance the smooth operation, so that the unit running smoothly, safe and reliable. 3, installation and maintenance convenience: the direction of import and export of the pump can be adjusted according to the pipeline, nine adjustable angle installation, easy maintenance. 4, stainless steel sleeve: shaft sealing position is relatively easy to rust, direct-coupled pump shaft once corroded, easy to cause mechanical seal failure. KD-type pump fitted with stainless steel bushings to prevent corrosion occurred, improve the shaft life, reducing the operation and maintenance costs. 5, Bearing: pump equipped with motor, Y (Y2) 280 below the shaft end bearings (including Y180 below the blade end bearings) with closed bearings, to remove the normal conditions for the motor bearings to the maintenance work. 6, mechanical seal: mechanical seal base member generally use rubber bellows structure, the traditional mechanical seal on the shaft seal from the O-ring seal to the two pieces of rubber seal to improve the sealing effect. Third, the working conditions of flow: 4 ~ 1600m3 / h Head: 4.5 ~ 50m Medium temperature 0 ℃ ≤ T ≤ 130 ℃ Ambient temperature ≤ + 40 ℃ System maximum working pressure: ≤ 1.6Mpa
