6 major requirements in the installation of pump pipelines

[Asia Pump Network News] Pump installation to take into account many factors, of which the more important is the installation of the pipeline. Pumps and tubes are often used together, both need to consider each other, work together to achieve the best results. That the installation of the pump pipe need to pay attention to what? 1 installation of the water pipe, the horizontal section of the level or upturned will make the inlet pipe to gather air, reduce the vacuum hose and pump, the pump suction head Reduce, reduce the amount of water. The correct approach is: the horizontal section should be slightly tilted to the direction of the water source, should not level, but not up tilt. 2. Into the water pipe with more elbows in the water inlet pipe used more elbow, will increase the local water flow resistance. And bend should be turned in the vertical direction, not allowed to turn in the horizontal direction, so as to avoid the accumulation of air. 3. Pump inlet connected directly to the elbow This will make the water flow through the elbow into the impeller uneven distribution. When the inlet pipe diameter greater than 143c pump inlet, eccentric reducer should be installed. Eccentric reducer plane part to be installed in the above, bevel part installed below. Otherwise, gather air, reduce the amount of water or pumping out of water, and a percussion sound. If the inlet pipe and pump inlet diameter equal, should be in the pump inlet and elbow plus a straight tube, straight pipe length of not less than 2 to 3 times the diameter of the pipe. ? 4. Bottom valve inlet pipe installed in the next section is not vertical If installed, the valve can not be closed on their own, resulting in water leakage. The correct installation method is: equipped with a valve at the end of the inlet pipe, the next section is best vertical. As a result of the terrain conditions can not be vertical installation, the water pipe axis and the horizontal angle should be 60 ° or more. 5. Inlet water inlet position is not (1) inlet pipe inlet from the pool bottom and pool wall distance is less than the inlet diameter. If the bottom sediment and other dirt, the inlet from the bottom of the pool is less than 1.5 times the diameter, it will cause poor pumping or sucked into the sediment debris, plug the inlet. (2) Inlet pipe inlet water depth is not enough, it will cause the water around the inlet pipe whirlpool, affecting water, reduce the amount of water. The correct installation method is: small and medium-sized pumps into the water depth of not less than 300 ~ 600mm, large pumps shall not be less than 600 ~ 1000mm. 6. Outlet nozzle above the normal water level in the outlet If the outlet above the normal water level in the outlet, although the increase in the pump head, but reduces the flow. If due to the terrain conditions, the outlet must be above the water level out of the pool, you should install the elbow and short pipe in the nozzle to make the pipe siphon, reducing the height of the outlet (Extended: 2016) Beijing Oil Show Pumps Valves Pipe Fittings Exhibition Information 2016 Exhibition 2016 Xiamen Industry Fair
