Title: Pump Question
Post by: Mark Betts on May 02, 2004, 01:31:13 am

Hi

Can someone please answer this question.



What would happen if you disconnected the flow control valve so in effect there was no control over adjustment of pressure and just put a blank peice in where the control valve should be? IE In effect just blocking the pipe.

Would the pump just build up in pressure and then eventually go POP!!! or burst a pipe or is it feasible to run the machine this way?

Thanks

Mark

you would have to put a return hose to water tank

or bypass

I could be wrong

Mark,

The result would depend on the pump. In most cases the flow control valve is simply an adjustable 'leak' of part of the pump output back into the tank.

1] Replacing the control valve wth a strait-through pipe between pump output and machine output would result  in the pump delivering pressure up to the setting of its' internal bypass.

2] A blanking at this point would have the same effect but with no output from the machine.

3] A blanking on the return pipe would have the same effect as having the flow control valve on the full-pressure setting.

The reason I wrote "in must cases" is that it is possible to set up a system with a non-regulated pump (no internal by-pass) and to compensate with a flow control valve that had a limited range. I know of no commercially produced CC machine that has this set-up, but in such a system pump damage/burst pipes could result from setting 2] & 3]  above.
