臥式雙吸泵@豐潤臥式雙吸泵@臥式雙吸泵350口徑

Suction tank should be easy to clean before. (4) Considering the landing of the water surface, the position of the suction pipe end should have enough submerged depth to prevent the intake from the whirlpool. (5) Before installation, to carefully check whether the bottom valve is flexible, at the same time in order to facilitate inspection and maintenance, to consider a good installation method. (6) The gate valve installed on the inlet side shall be installed in a horizontal direction or tilted downwards to avoid the accumulation of air. Import Side Gate valve In addition to inspection, switching outside, must be fully open. At the same time should try not to let the air from the sealing sleeve area. (7) The bending part is as smooth as possible, reducing the number of elbows, and should try to avoid being set close to the inlet of the pump. (8) When there is a different diameter tube, in order not to allow air to accumulate, should use eccentric type of pipe. (9) For parallel operation of the pump inlet pipe, it is advisable to use a separate water inlet pipe. If the use of direct to the common mother tube, easy to occur the imbalance of import pressure. The drive (motor) drives the impeller to rotate through the pump shaft, and the blade of the impeller drives the liquid to rotate together.

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、軸套和葉輪的材質，可以輸送含有泥沙的渾水。改變承壓零件的材質，可以提高泵的進口壓力.泵的軸封一般采用軟填料密封，如有特殊要求，也可改裝機械密封。從電機方向看泵，泵為逆時針旋轉，按用戶要求，也可改為順時針旋轉。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.

根據水泵行業規定，Sh型與S型兩大系列中開泵并存，直至統一設計出新型泵代替這兩個系列時為止。本產品主要用于工廠、礦山、城市、電站給水農用排澇灌溉、各種水利工程用泵和采暖空調系統等場合
