The structure of the DL vertical multi -level booster pump is generally versatile. From the DL vertical multi -stage supercharged pump structure diagram, it can be seen that there are still many components of the vertical multi -level booster pump. Sealing pads, nuts, sales, motors, joint shafts, connectors, mechanical seals, shafts, middle sections, shaft sleeves, bearing tiles, water -to -water pipe components, etc.

The inlet port of the vertical multi -level booster pump is on the pump seat, the spit outlet is on the back section, and the 180 -degree horizontal direction appears. It needs to be inhaled and spit out. The layout can choose the level of the booster pump according to the needs of the raising. The pump shaft is made of high -quality alloy structure steel. There are impeller, balance drum, shaft cover B, and small round nuts fixed on the shaft to form a rotor component. The shaft is equipped with two angle contact ball bearings, which is used to make rotor components. The upper end of the pump shaft and the bottom of the motor shaft are connected through the claw type shaft. The sealing device is seal with soft fillers and mechanical seals. The axis cover of the friction in the process of soft fillers is made of high -quality carbon steel and increased the abrasion resistance by quenching treatment. The impeller is made of cast iron, because the impeller is deressed before and after, there will be axial force, and the remaining small axial force will be affected by the two corners of the axis. The balancing device composed of drums can be replaced after wearing. The pump seats and the middle section are equipped with a ritual and sealing ring, which is used to reduce the high pressure water leakage back into the water. The sealing ring can be replaced after wear. The angle contact of the multi -level booster pump is lubricated with calcium -based butter. The sliding bearing at the lower end is used to transport liquid lubrication. The selection direction of the vertical multi -level booster pump is turned from the motor to the counterclockwise direction.
