The HZB253-640 booster pump is a horizontal, single-stage, double-suction, vertically upward flow, single volute pump. Its reliability and efficiency make it an ideal booster pump for power plant boiler feedwater systems.
Structure:
The pump mainly consists of a volute, the driving end and the non-driving end covers, shaft, impeller, bearing housing, sealing components, and so on. The shaft is supported by a single-row cylindrical roller bearing at the driving end and a single-row angular contact ball bearing at the non-driving end. The impeller is axially positioned by adjusting the nut and key, and the replaceable stationary wearing ring reduces leakage. It utilizes a mechanical seal to ensure reliability and sealing of the pump.
Working Principle:
The working principle of the HZB253-640-03-07 booster pump is based on its double-suction design, which allows it to simultaneously intake fluid from both sides, thereby improving suction efficiency. The lubrication system is provided by an oil slinger ring to ensure sufficient lubrication of the bearings during operation. The cooling system is achieved through a bottom cooler, ensuring the pump's long-term operation.
When performing maintenance on the HZB253-640-03-07 booster pump, some commonly used parts may need to be inspected and replaced to ensure the pump's stable operation and prolong its lifespan: casing, driving end cover, non-driving end cover, shaft, impeller, adjusting nut, key, stationary wearing ring, bearing housing, bearings, mechanical seal, shaft sleeve, alignment ring, o-rings, etc.
