卧式双吸泵@丰润卧式双吸泵@卧式双吸泵350口径

Suction tank should be easy to clean before. (4) Considering the landing of the water surface, the b 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 b. (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.

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.

根据水泵行业规定，Sh型与S型两大系列中开泵并存，直至统一设计出新型泵代替这两个系列时为止。本产品主要用于工厂、矿山、城市、电站给水农用排涝灌溉、各种水利工程用泵和采暖空调系统等场合
