Precautions before installation of the pipeline in order to make the pump not due to the installation of pipes and increase excessive force, suction pipe, pressure pipe and valve class to their own support. When the takeover flange is screwed to the pump flanges, it is necessary to confirm that the flange surface is indeed tightly fastened and cannot be excessively tightened by bolts. In addition, considering the expansion of the pipeline, the subsidence of the foundation and the removal of the pump and valve, the Zui is good at using flexible joints near the pump. However, special attention should be paid to, after the pipeline is installed, the flexible joint itself must be rigid joint, so that it does not have elongation under the pressure of the phenomenon. When the pipeline should be buried in the ground, we should consider that the foundation should be adapted to uneven subsidence, freezing and so on. (1) In order to prevent air leakage, the suction pipe should be used as far as possible to use the orchid joint. (2) The layout of the suction pipe road, to try to make from the water suction to the pump has an upward slope (about 1/50) so that the tube does not accumulate air, but when the pipe submerged under the water, from the water absorption to the pump orientation of the slope. (3) The suction tank shall be provided with decontamination equipment (barrier grille).

2、外形美觀：直線型的外觀并在泵蓋上附加強(qiáng)筋，內(nèi)置式密封潤(rùn)滑結(jié)構(gòu)使泵整體結(jié)構(gòu)渾然一體，靈活的結(jié)構(gòu)設(shè)計(jì)使泵更加精美大方。
3、率：采用CFD計(jì)算流體動(dòng)力學(xué)，分析計(jì)算出泵內(nèi)壓力分布和速度分布關(guān)系、優(yōu)化泵的流道設(shè)計(jì)，確保泵有的水力形線，提高了泵的效率。泵體采用雙流道設(shè)計(jì)，以減小徑向力。泵體、泵蓋、葉輪等過(guò)流部采用樹(shù)脂砂板模造型，保證了外觀及流道尺寸以及泵的水力效率。S、SA系列雙吸中開(kāi)泵效率比一般雙吸泵高3～5％。
4、平衡精度高：轉(zhuǎn)子部件動(dòng)平衡精度為G1。0級(jí)。
5、軸：軸短且剛性好，增加軸徑，以延長(zhǎng)軸承和機(jī)械密封的使用壽命。軸為全封結(jié)構(gòu)，確保了不與介質(zhì)接觸，不銹蝕，使用壽命長(zhǎng)。
6、雙蝸殼：高揚(yáng)程泵采用雙蝸殼結(jié)構(gòu)，減輕了徑向力。

Pipeline installation should try to overcome the phenomenon of too much elbow, the elbow radius of the pipe should be larger. (3) Check whether the packing seal leaks too much or too little, especially the inlet pipe. Pipe length should not be too long. (2) When using bending pipe, the straight pipe part before and after the pump import and export should be at least 5~10 times the diameter of the pipe. (3) In order to prevent the reversal of parking, water hammer phenomenon, in the pump pressure out pipe should be equipped with a check valve, in order to adjust the flow, in the pump pressure out of the pipe should be equipped with a gate valve; the check valve is installed between the pump and the gate valve. (4) After the piping is installed, further check the neutral of the pump and motor couplings. (5) Install all pipes, such as water seal pipe parts, cooling pipe parts, etc. Each pipe should be smooth, sealing should be strict. (6) The pressure gauge joint parts are installed in the pump inlet and outlet flange all the open pump is left with the installation pressure gauge screw hole, screwed down for the pressure gauge joint parts of the wire plugging, according to the technical inbation provided by the pump factory, select the appropriate pressure gauge and vacuum meter installed in the pump outlet and import respectively.
