Start, run, stop (a) start: WARNING: To the operator's safety, do not go beyond the pump nameplate operating conditions, so as not to endanger the safety of equipment and operating personnel. To ensure smooth operation and maintenance of pumps and other actions, please refer to the instructions. 1, the pump should be preceded start moving rotor disk, check the rotor is flexible. 2. Check the motor rotation is consistent with the steering pump. 3, close the pump outlet valve, pressure gauge cocks, liquid or vacuum conveying system to exclude air pump suction pipe and in vivo (non-empty start running). 4. Check the tightness of the security situation in the pump and motor bolts and around the pump, the pump is ready to start in the basic structure of the state is composed of a multi-stage pump water segment, water, middle, end caps, impeller, pump, pump shafts, bearings 80D-12X3 horizontal multi-stage centrifugal pumps, seal rings, stuffing and other member. 1, the impeller is the core part of the multi-stage pump, which speed up force, the impeller blades and played a major role in 80D-12X5 horizontal multistage centrifugal pump impeller assembly before by static test. Requirements on inner and outer surfaces of the impeller smooth to reduce flow friction losses. 2, the water segment, the water segment, the middle, also known as the pump casing 80D-12X6 horizontal multistage centrifugal pump, which is the subject of a multi-stage pump. Fixed play a supporting role, and connected to the installation of the bearing bracket. 3, the role of the pump shaft is connected by means of coupling and motor, the torque of the motor is transferred to the impeller, so it is capable of transmitting mechanical main components. 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! 80D-12X3 horizontal multistage centrifugal pump _ _ mine multistage centrifugal pump wear by Anguo City Pump Co., Ltd. Shi Yuan. Anguo Shi Yuan Pump Co., Ltd. (www.shiyuanbeng.com) strong, credible, in Baoding centrifugal pump industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Shiyuan water pump into the brilliant and you work for a better future!
