Removing Press without opposite steps. (Ii) Installation: 1, the preparatory work before installation. (1) Check the pump and motor. (2) preparation tools and lifting machinery. (3) check the machine foundation. 2, the installation sequence: (1) the entire pump transported to the site from 100D45X3 corrosion resistant multi-stage, with the base are already installed when the motor Phi flat base can be removed without removing the pump and motor (2) the base on the foundation, Near ground screw wedge pad horn, elevate the base about 20-40 mm, prepare the filling water propeller after leveling. (3) Check the level meter base level degree, pull tight to the foot after leveling nut filled with water base mud. (4) After 3 to 4 days after the cement to dry, and then check the level of degree. (5) the dirt flat base support plane, foot pump, motor feet washed clean on the net, and the pump and motor on the base. (6) Adjust horizontal shaft, tighten the nut after proper leveling to prevent walking, to be installed after the motor adjustment pad at sub-level at between iron multistage centrifugal pump and leave some couplings clearance. (7) the flat foot on the coupling, check the pump axis and motor axis are coincident, if not coincidence, at the foot of the motor or pump pad sheet, so that the two couplings foreign and flat feet 100D45X6 multistage centrifugal pumps with flat seal, then remove the pad a few slices of thin iron sheets, After a plane piece of iron to replace the iron plates, and re-check the installation. In order to check the accuracy of the installation in several opposite positions with a feeler 100D45X4 multistage centrifugal pumps, measuring two coupling plane gap coupling plane week, the largest and the smallest gap difference can not be more than 0.3 mm, difference upper and lower ends or left and right of the center line shall not exceed 0.1 mm. Failure three gauge water pressure but still reasons: 1. too much resistance outlet pipe 3. 2. Turn right direction outlet pipe valve is not open impeller clogged 4. Solution: 1. Check or cord short pipe 2. Check Motor two intermodulation 3. Open the outlet valve 4. remove dirt impeller failure to reach the design flow rate of four reasons: 1. There are air intake 2. Due to lower the water level inside the submerged deep enough impeller blockage 3. 4. rotor portion severe wear solutions: 1. Check the leak site and the exclusion 2. extend deeper water pipe flooded the depth 3. Remove and drops in addition to foreign bodies 4. Replace the seal ring 100D45X3 from wear and corrosion multistage | multistage centrifugal pump. | drainage pumps provided by the Anguo City Pump Co., Ltd. Shi Yuan. Anguo Shi Yuan Pump Co., Ltd.
