Keyword: The installation technology key of centrifugal pump of installation of centrifugal pump water pump depends on deciding water pump installs height. This height is to show fountainhead surface reachs center of water pump impeller the vertical distance of the line, it and allow suction vacuum height cannot confuse sth with sth else, the indicative permission on water pump nameplate or product manual suction vacuum height is to show the vacuum on section of water pump water inlet is worth, and it is to be below 1 standard atmosphere; Water is warm below 20 Celsius circumstance, have a test and determine. It did not consider bibulous conduit form a complete set condition of the following flow. And water pump installation should be to allowed suction vacuum height to deduct bibulous conduit highly after loss lift, that part that remains is numeric, it should overcome practically form bibulous height. Water pump installation cannot exceed computational value highly, otherwise, water pump will be smoked do not sail upstream come. Additional, the obstruction loss lift that the size that affects computational value is bibulous conduit, accordingly, appropriate uses the shortest pipeline to decorate, install fittings of curved first class less as far as possible, also can consider to match appropriately a few bigger the conduit of caliber, in order to reduce the velocity of flow inside the canal.
Ought to point out, the tall Cheng of place of water pump installation and water are warm when be different from experiment condition, altitude of for example place 300 meters of above or be crossed by the Shui Wenchao of pump water 20 Celsius, calculate the value should undertake correction. Differ namely the saturated vapour when 20 Celsius water are warm presses the air pressure that altitude tall Cheng handles and prep above force. But, water Wen Wei when 20 Celsius are the following, saturated vapour pressure can be ignorred.
Install a technology to go up from conduit, bibulous conduit asks to have strict sealing, cannot flat, slack, the vacuum that will destroy water pump water inlet to be in otherwise is spent, make water pump gives water quantity to decrease, serious when smoke even do not sail upstream come. Accordingly, the interface that should make good tubing seriously works, assure quality of conduit connective construction.
