Can the inlet pump and outlet pump of the large tank in the storage tank area be combined?
Thread Content
For the design drawings provided by the design institute nowadays, there is one material input pump and one material output pump for the large material tank. I communicated with the design institute to see if it would be possible to combine them, but the institute considered it inappropriate. Could anyone who has experience with this please offer some help? Thank you
1. If input is given and the pumps run simultaneously, they cannot be shared； 2. If the pumps operate in a start/standby mode and the input and output cannot be stopped, they cannot be shared ； 3. Additionally, while the shared process for the pumps is simple to implement, it is difficult to arrange and construct during on-site piping work; the processes and the switching of control valves are very complex, which also leads to easy confusion in operation. 4. If the entrance and exit are separated, the process and layout become much simpler to implement.
It is technically feasible. It is automatically controlled by several switch valves; my previous factory was designed in this way. But the prerequisite is that unloading and loading cannot occur simultaneously
FH 1. If input is given, both pumps will operate simultaneously and cannot be shared； 2. If the pumps operate in a start/standby mode and the input and output cannot be stopped, they cannot be shared ； 3. Additionally, while the shared process for the pumps is simple to implement, it is difficult to arrange and construct during on-site piping work; the processes and the switching of control valves are very complex, which also leads to easy confusion in operation. 4. If the entrance and exit are separated, the process and layout become much simpler to implement. 1. The time of input and output can be controlled manually; it is basically possible to control when input and output occur ； 2. The technological requirements can be met; however, the process of piping on-site and the use of valves are indeed much more complex. Different operators are responsible for different tasks: the output pump is operated by the workshop staff, while the input pump is operated by the warehouse staff. Clear markings are placed on the valves. This post was last edited by Xu Feng on 2009-2-18 09:08.]
Furthermore, since the head and power of the input pump and the output pump are different, does this have an impact on the transportation of the material?
The main issues are as follows: 1. Whether it is a batch operation, allowing the input and output pumps to operate at different times. 2. The key factors are flow rate and head; it is important that the flow rates of the inlet and outlet pumps be the same, and that their heads be either the same or fairly similar.
It can be set to operate intermittently, staggering the input and output； Regarding head and flow rate, if the requirements for output are met, then the impact on the input pump should not be significant; after all, the input pump is connected directly to the large tank. A higher or lower flow rate mainly affects the speed at which goods are unloaded, while the head value should not have much of an impact
In reality, it’s completely possible! In the units I was working in before, there was one pump for both output and input functions. It was usually in output mode; when feeding material, two operators would check to ensure that the valve was in input mode, and once the input process was complete, it would be switched back to output mode. The key point is that the number of times material needs to be fed there is relatively low – once a week is enough. If it has to be done frequently, it becomes troublesome, so it’s better to handle them separately
