The pump is used only for cleaning
Thread Content
Due to the requirements of standby unit management, switching operations must be carried out regularly. Poor hygiene of the operating pumps can result from weather conditions; for important operating pumps, switching is performed solely for the purpose of cleaning. Is such an approach necessary?
Personally, I think cleaning is a side effect of switching pumps. The main purpose of switching pumps should be to regularly check the operating condition of the backup pump, so that it can be switched over properly when needed. Cleaning should be done as an incidental task; if pumps are switched over just for the sake of cleaning, then the timing isn’t managed properly.
Turning the pump around is done to check its operating condition, to carry out regular inspections and maintenance, and to ensure that the backup pump can be started at any time to operate normally; cleaning is merely an additional task performed as part of this process.
The pump should be switched over regularly; here we switch it on a regular basis, allowing it to operate for a day before switching it back. It’s still better to conduct regular trial operations.
Agreed: regular pump reversal, regular trial runs, and cleaning along the way!
Regular pump reversal is still necessary. When shutting down a pump, one can be somewhat confident; if the standby pump has never been turned on before, it’s uncertain whether it will operate properly when started.
I’m not sure what the cleaning schedule is like where you are. I think it mainly depends on the cleanliness of the pump; if there is a lot of dust present. Regular cleaning is very necessary. However, the pumps in our workshop are also located in dust-filled areas, and it seems they are cleaned very rarely:L
I think it depends on the purpose for reversing the pump. One reason is that the filter screen gets clogged, and the pump has to be reversed in order to clean the filter screen. Another option is: each pump has a required operating time, and once that time is reached, the pump must be switched out. Then the pump is inspected and maintained for future use!
It is necessary, but not too frequently, to avoid placing excessive strain on the operators. To maintain good hygiene in the pump system ； Protect the safety of maintenance personnel ； To ensure the long-term stable operation of the engine crew, it is necessary to switch off the pump for cleaning purposes under these three prerequisites.
The main purpose of the backup pump is actually to ensure that the spare pump remains in good condition and is able to operate properly!
The main purpose of switching pumps should be to regularly check the operating condition of the backup pump, so that a smooth switch-over can take place when necessary. Cleaning should be done as an incidental task; while it’s not impossible to switch pumps for cleaning purposes, the cost is somewhat high. More established companies do not do this
Replacing the pump means checking to see if there are any problems with the backup pump!!! We do this every two weeks, as it’s required by regulations. I’m not sure if that’s scientific or not
It depends on the needs. Under normal circumstances, there’s little need to empty the pump for hygiene reasons; but if it’s for safety and standard operating procedures, then it’s necessary: lol. We basically clean it every day
Pumps are not intended for hygiene purposes; their main function is to ensure the proper operation of the pumps and to enable timely maintenance. This way, if one pump develops a problem, the backup pump can be brought online immediately. If the backup pump is not used for an extended period of time, an accident could lead to production shutdowns
The main function of the backup pump is actually to ensure that the standby pump remains in good condition and is operating properly. The frequency at which the pump needs to be serviced can be determined based on the operational conditions; for example, how long it takes for the medium in the pipes to accumulate scale, or how long it takes for solid particles to accumulate in large quantities. It is really unnecessary to drain the pump just for cleaning, unless the dirt on the pump has affected its proper operation.
Requirements for pump switching and commissioning: 1. Pump switching and commissioning shall be carried out once per quarter, and these operations must be completed during the day shift. If it falls on a holiday, the deadline will be postponed; if the switch-over can be completed within one quarter due to maintenance or other reasons, there is no need to carry out the switch-over again. 2. For the raw material pumps of various units, as well as the pumps that can directly affect product quality, there are certain risks associated with commissioning and switching operations. Therefore, the responsible process engineers will decide whether to commission or switch to a backup pump depending on the specific circumstances, but this should not occur more than once per quarter. 3. Every quarter, the equipment management staff will, based on the actual operating conditions of the equipment, inform the team leader about the specific equipment that needs to be switched over or tested; upon receiving such notification, the team leader must carry out the tasks as specified. 4. Detailed records of pump switching and trial operation should be kept in the shift handover log.
Pump rotation is not primarily aimed at maintaining hygiene, but rather to prevent fatigue that can occur due to the long-term operation of the pump in use. If a backup pump is not used for an extended period, it may develop faults; regular pump rotation ensures that the backup pump is ready for use when needed, while preventing the pump currently in use from operating for too long and thus shortening its lifespan.
