Beijing pipeline pump installation maintenance sales

Beijing pipeline pump maintenance sales pipeline pump installation basic structure is composed of six parts are the impeller, pipeline pump, shaft, bearings, seal rings, stuffing box. In accordance with the installation it can be divided into vertical and horizontal pipeline pump pipeline pump. Universal letter ISG and ISW 1, centrifugal impeller is the core part, it speed up force, the impeller blades and played a major role in the assembly before the impeller by static test. Requirements on inner and outer surfaces of the impeller smooth to reduce flow friction losses. 2, pipeline pump, also known as the pump casing, which is the main water pump. Fixed play a supporting role, and connected to the installation of the bearing bracket. 3, the role of the pipe shaft is connected by means of coupling and motor, the motor torque transmitted to the impeller, so it is the transmission of the main components of mechanical energy. 4, the support shaft bearing is set in the shaft member, there are two kinds of rolling bearings and plain bearings. Rolling refuel using butter as a lubricant to the appropriate volume is generally much 2/3 to 3/4 may have a fever, there are too few sound and heat! Bearing using transparent oil as a lubricant, fuel oil level line. Too many cheap oil to bleed and drift along the shaft, too little overheated bearings and also burned accident! Pump bearing temperature during operation up to 85 degrees generally run at about 60 degrees, if necessary to find the cause of high (if there are impurities, oil is black, is water) and timely manner! 5, sealing ring, also known as Save the drain ring. Too gap caused by the impeller inlet and pump water into the pump housing between the high pressure region through the gap of the low pressure area, the impact of pumping capacity, reducing efficiency! Gap is too small will cause the impeller and pump casing friction wear. In order to increase the resistance to reduce leakage reflux, delayed impeller and pump housing that life, with sealing ring in the pump casing and impeller foreign aid junction edge, sealing the gap is maintained between 0.25 ~ 1.10mm is appropriate. 6, stuffing consists of packing, lantern ring, packing tube, packing gland, seal tube. Role stuffing mainly to closed the gap between the casing and the shaft, to prevent the water within the pump does not flow out to not let the outside air into the pump. Always keep the vacuum pump inside! When the shaft and packing friction heat to rely on the seal to seal the circle take control of water to cool the filler! Maintain the normal operation of the pump. So the pump running roving inspection process checks for stuffing particularly pay attention! Running 600 hours or so should be replaced on the filler.
