雙吸循環(huán)泵@灤縣雙吸循環(huán)泵@雙吸循環(huán)泵400口徑

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 information provided by the pump factory, select the appropriate pressure gauge and vacuum meter installed in the pump outlet and import respectively.

本系列泵是單級、雙吸、水平中開式離心泵，適用于汲送清水和無腐蝕性的液體。介質(zhì)溫度80℃。軸承體通人冷卻水后，可輸送130℃以下的熱水。改變密封環(huán)、軸套和葉輪的材質(zhì)，可以輸送含有泥沙的渾水。改變承壓零件的材質(zhì)，可以提高泵的進(jìn)口壓力.泵的軸封一般采用軟填料密封，如有特殊要求，也可改裝機(jī)械密封。從電機(jī)方向看泵，泵為逆時針旋轉(zhuǎn)，按用戶要求，也可改為順時針旋轉(zhuǎn)。jdhuiquan4.13

When the open pump reaches full speed operation, it is necessary to carefully check: (1) Pay attention to the pump import and export pressure, with the export gate valve adjustment so that its pressure control in the specified range. (2) Whether the bearing is overheating, the ideal temperature for bearing operation is 40~60℃, and the temperature rise does not exceed 35 ℃. If the temperature is stable and does not rise again, it may be slightly above the above range, but more than 80 ℃ must not be allowed. If more than 80 ℃, the bearing body shall be fitted with cooling water. Filler leakage water is dripping appropriate (about 30 drops per minute). After the pump starts with a wrench to adjust the filler cover nut tightening to adjust the leakage amount, in order to meet the leakage requirements. (4) Keep track of the operation on a regular basis. Pipeline Installation Steps: (1) After the installation of the equipment, joints, discharge pipes and valves, do not use the pump as a pipe and valve support, require adequate attention to make the pipe and valve weight and excessive tightening force, etc. do not affect the pump body. Installation accessories should also be taken care to avoid allowing the pump to withstand any external force. To reduce head loss.

根據(jù)水泵行業(yè)規(guī)定，Sh型與S型兩大系列中開泵并存，直至統(tǒng)一設(shè)計出新型泵代替這兩個系列時為止。本產(chǎn)品主要用于工廠、礦山、城市、電站給水農(nóng)用排澇灌溉、各種水利工程用泵和采暖空調(diào)系統(tǒng)等場合
