In the event of a major failure, the entire water treatment process will be paralyzed, bringing great inconvenience to the people's lives and production. According to the current analysis of the operation of the pump in the S series, the common faults are: The impeller has been subjected to surface corrosion in the sewage for a long time, the early fatigue fracture of the blades, the wear of the pump body overflow parts, the bending of the pump shaft, the burnout of the motor and the bearing, etc. It is very important to study the operation Safety, through the research of this content, not only improve the safety of the pump, but also improve its service life. And in the process of water treatment work, the use of the system is often changed, if not in accordance with the needs to be met, will affect the normal operation of production, resulting in greater waste. In order to manage effectively, it is necessary to carry out remote monitoring and field control of production system, and in order to improve production efficiency and safety, it is also necessary to detect the key parts of the pump in the S series. Thus, the research of automatic control technology is an important technology development trend.
主要适用于工厂、矿山、城市给水、电站、农田排灌和各种水利工程。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.
