About the startup process of high pressure multistage pumps

Start-up process of high-pressure multi-stage pump, open high-pressure multi-stage pump inlet valve, slightly open outlet vent valve, wait for vent to see oil, and after no gas, close vent valve; manually start auxiliary oil multi-stage pump, adjust lubricating oil pressure greater than 0.25 MPa, adjust the high pressure motor lubricating oil pressure to 0.01 ~ 0.05MPa, the lubricating oil branch return oil is normal; wear the labor insurance supplies, prepare the relevant tools; check the reaction feeding multi-stage pump inlet and outlet process, the raw material tank liquid level meets the opening Class pump requirements; open the reaction feed multi-stage pump back to the raw material tank process, notify the internal operation of the return tank regulator valve opening degree is not less than 40% (satisfy the multi-stage pump minimum flow is not less than 66 tons / hour), the external operation on-site confirmation The opening degree is normal; check the lubricating oil station oil level is appropriate, the lubricating oil sampling analysis is qualified, the oil filter filter differential pressure, pressure switch, pressure remote transmission and other instruments are used normally, the oil cooler process is normal, and it is used; Class pump, pressure gauge, wheel cover, wheel bolt, anchor bolt, valve, pipeline flange gasket intact; external operation report within the multi-stage pump condition is satisfied, internal operation interlock reset, observe the reaction in DCS Multi-stage pump multi-stage pump start conditions are met. Manually cranking two turns, the high-pressure multi-stage pump has no light and uneven.

Multi-stage pump scope: mainly used in high-rise building water supply, but also can be applied to factories and mines, enterprise water supply and drainage, and low-pressure boiler circulating water.

Multi-stage pump product features: 1. Advanced hydraulic model: high efficiency and wide performance range. 2, less operation, maintenance costs: the use of high-quality mechanical seals, wear-resistant, no leakage, long service life, low failure rate, with less operating and maintenance costs. 3, unique components, reduce noise: unique hydraulic components design, good overcurrent performance, to minimize flow noise. 4, vertical structure, small footprint.

After-sales commitment for multi-stage pumps:

First, the factory implements three guarantees (return, replacement, warranty), warranty for two years, lifetime maintenance, if there is quality problem within one year of warranty period, Liangbang will promptly replace or repair the product, after-sales service personnel After receiving the notice, the city will arrive within 12 hours and arrive within 48 hours of the area;

Second, the maintenance service during the warranty period is as follows:

1. Parts and components caused by manufacturing defects and hidden dangers are still repaired and replaced by new manufacturers free of charge.

2. After the expiration of the warranty period, we will track the system equipment for paid service to ensure the normal operation of the system. Special overhaul and overhaul: If any problems affecting the normal operation and performance of the pump are found, the multi-stage pump will be repaired or overhauled in a timely, accurate, complete and thorough manner.

3. Supply of spare parts: The spare parts required for maintenance are supplied by our factory, which is fast, high quality and reasonable price.
