Introduction to the basic knowledge of large pump storage pump

Introduction to the basic knowledge of large pump station storage pump set Pump units, electrical equipment and piping, valve and other hand houses. Pumping station role 1, is able to provide a certain pressure and flow of hydraulic and pneumatic power plant and engineering, said pumping and pumping station project. 2, the fuel tank, motor and pump These three things are the main components, but there are many auxiliary equipment, according to the actual situation need to increase or decrease, such as oil supply equipment, compressed air equipment, water filling equipment, water supply, drainage, ventilation equipment, Lifting equipment and so on. First, save the pump Overview Pump pumping layer with a water collection pit, pool pumping station pool water and sealing water, and discharged through the pump to the front pool, each sump 2 pumps, a Use a prepared. Save pump control system includes: level switch, control box, level alarm device. The sump level consists of 4 liquid level switches: 2 liquid level switches control the high and low liquid level on and off pumps; the other 2 liquid level switches control the high and low liquid level alarms. Level alarm level installed in the pumping station control room. Control box is located near the sump, installed manual / automatic control switch, in the automatic position by the liquid level automatically control the pump open, stop. When the switch is set to manual, the manual control of the water pump is started and stopped by the button. Control box and the control room there is a working condition of the pump and high and low level alarm indicator and alarm sounder. Second, save the pump structure Save the pump WQ series submersible sewage pump, the medium temperature does not exceed 60 ℃, the medium density ≤ 1200kg / m3, pH value in the range of 5 to 9, the rated voltage of 380V , Rated frequency is 50Hz, the rated voltage and rated frequency deviation is less than ± 5%, the motor can operate normally. The maximum diameter of solid particles passing through the pump shall not be greater than 50% of the diameter of the pump body outlet. Small Hardware and Electrical Network Xiaobian for everyone to introduce, from the pump inlet view, the impeller rotates counterclockwise. The submersible pump is composed of pump body, impeller, motor, bearing, shaft, seal ring, oil plug, cooling cylinder, wiring cavity, motor side mechanical seal, pump side mechanical seal, upper leakage probe, lower leakage probe and monitoring system.
