Washing tower feed water pump
Thread Content
I would like to ask everyone whether a standby pump for the washing tower feed water pump in a gasification system is equipped with interlocking What should be paid attention to in the daily maintenance of this standby pump?
The standby pump for the gasification scrubber tower feed water pump is interconnected via interlock; regular maintenance of this standby pump should focus on preventing blockages, and it also needs to be tested periodically.
Hehe, let me add my opinion too: Since this pump is used to transport high-temperature graywater, it requires a heating pump system; moreover, both the pump and any lubrication system (if present) need to be part of the interlock system. It is advisable to switch the pumps around every 3–4 months. The pump chamber of the standby pump should be rinsed with tap water, and if the pump is not used for an extended period, the water inside its chamber must be drained.
The interlock for the feed pump itself can be installed or not; we have chosen not to install it. However, if a high-speed pump is used, an interlock for the lubrication system must be in place. If the liquid being transported contains a high amount of solids, it is necessary to switch pumps frequently to prevent blockages at the inlet and outlet, and the sealing flush water inside the pump chamber should be turned on regularly.
The standby pump is interlocked for automatic startup; routine maintenance includes the oil system, power supply status, switch positions, and anti-freezing measures.
The standby pump should be regularly checked to ensure that its hot standby status is normal. This includes: inlet and outlet pipelines, pump accessories, pressure gauges, pressure regulation, etc.
It is a high-pressure pump with high power; it usually does not have an automatic start function. The motor of the standby pump is in electric heating mode, and the circulating water as well as the seal water are in use to ensure that it can be started at any time. The pumps are switched regularly, and the inlet filters that are not in use are disassembled and cleaned
