Shanghai Panda Model 50-125A Horizontal Horizontal centrifugal water pump prices in Daxing District ..

Shanghai Panda Horizontal centrifugal pump hot water | 50-125A horizontal centrifugal pump price |. Daxing District panda before installation centrifugal pump to start preparations for a centrifugal pump Check the oil before starting the name, model, key performance and raise Number of compliance with the requirements of technical documentation; bearing lubrication system, sealing system and cooling system is intact, bearing the oil, water is smooth; movable pump rotor disc from 1 to 2 to check whether there is friction or rotor jamming; in coupling or belt guards nearby, etc., if there is interfere with the rotation of debris; pump, bearing, motor foundation bolt is loose; valve or pump attachment system should be in operation when the pump is the smallest load position, close the outlet valve; inching pump, to see whether the design of the steering wheel turned to the same, if not, it is necessary that the impeller is fully stopped, adjusted the motor terminal before the restart. b. Centrifugal pumps filled with water before starting, the pump housing must be filled with water and the water pipe, which is the next because of the presence of air, the pump suction vacuum can not be formed and maintained. c. centrifugal pumping hot liquids warm multistage centrifugal pump, such as power plant boiler feed pumps must be warm before starting the pump. This is because when you start to pump, heat to water flowing through the pump, so that the pump quickly rises from room temperature to 100 ~ 200 ℃, which causes the temperature difference between inside and outside the pump and between the various components, if not long enough Transfer time and appropriate measures to control the temperature rise, uneven expansion will make the entire pump, resulting in various parts of the pump deformation, wear, vibration and bearing axle accident. Second, notes centrifugal pump is a vane pump, relying on rotating impeller during rotation, due to the interaction between the blades and the liquid leaves the mechanical energy transmitted to the liquid, the pressure of the liquid can be increased to achieve the purpose of transmission fluid. Centrifugal pumps start to pay attention to four points: ① lift at a certain speed centrifugal pump produced a limited value. Traffic and shaft power operating point depending on the unit system connected to the pump case (difference, the pressure difference and the pipeline loss). Lift with the flow rate change. ② stable, continuous delivery, flow and pressure pulsation. ?
