Pressure gauge installation location
Thread Content
Is it behind the pump outlet valve, or in front of it? I mean, between the outlet valve and the pump outlet, right? ? Let’s discuss it; I’m relatively in favor of what’s behind the export valves
It should be placed before the pump outlet valve, and only before that valve; because when the pump is started, the outlet valve should be closed while the inlet valve is open. As pressure rises after the pump starts, the outlet valve can then be opened based on the readings from the pressure gauge. What does it matter if it is installed behind the outlet valve?
It depends on which section of the pipeline’s pressure needs to be controlled; if it’s the pipe before the valve, it should be installed there, and if it’s the pipe after the valve, it should be installed there as well.
By supporting an outlet valve, accidental closure during operation can be avoided.
Under normal circumstances, it should be installed in front of the valve; of course, if the outlet pipeline is long, it’s also possible to install another gauge to facilitate monitoring of the pressure behind the valve (far from the pump). :lol
What the owner wants to measure and control is the pressure after the outlet; so what’s the point of installing it in front? After all, what we need is a stable pressure after the pump. It’s recommended to install it after the outlet
Under normal circumstances, it should be installed in front of the valve; of course, if the outlet pipeline is long, it’s also possible to install another gauge to facilitate monitoring of the pressure behind the valve (far from the pump). I agree with the view from the 5th floor
From a design perspective, installing it in front of the valve makes it convenient to observe and use when starting the pump. I understand the intention behind your question; just install one piece after that! I want to watch that, I want to see that! :lol
In front of the pump outlet valve, so as to check whether everything is working properly when the pump starts
Install a pressure gauge in front of the pump outlet valve; use the readings to assess the pump’s operation and determine whether it meets the specified values, then make adjustments as necessary. During the production process, the bypass valve is adjusted as needed. When installed after the outlet valve, it only measures the pressure in the outlet pipe.
It should be installed before the outlet valve, as it is used to monitor the pressure of the pump; if it’s the pipeline pressure, then another unit can certainly be added.
I have operated pumps installed in front of the outlet valve; when starting the centrifugal pump, I adjust the opening degree of the outlet valve by observing the reading on that pressure gauge.
It is more appropriate to install it in front of the valve. Sometimes several pumps operate simultaneously; with a combined outlet pipe, installing it behind the valve means that the pressure gauge will still show readings regardless of whether those pumps are running or not, in which case it loses its meaning
An outlet pressure gauge is used to measure the pressure at the pump’s outlet. For example, with a centrifugal pump, it is necessary to close all the outlet valves in order to measure the pressure; but what if valves are already installed there? How can the pressure be measured in that case?
Of course, it’s in front of the outlet valve. Of course, this is possible only if pumps such as centrifugal pumps can have their flow rate adjusted using the outlet valve, and if the pump can withstand pressure buildup. Installing it in front allows for checking whether the pump is delivering the required flow rate and what the pressure head is like. If it’s installed behind the valve, its usefulness is limited. If what’s behind the outlet is an open container, then the reading on the pressure gauge will always be 0
When the water pump is operating normally, the valve is in the open position. A pressure gauge installed either before or after the valve can display the pressure at the pump outlet ； But things are very different when the pump starts. If installed behind the valve, it may render the installation of a pressure gauge pointless, as the pressure is zero when the valve is closed. So it should still be installed in front of the valve. When special requirements apply, one piece is installed at each end.
If there is only one pressure gauge, it should be installed in front of the outlet valve; it is essential to use this gauge as a reference when operating the pump. To monitor the outlet pipeline pressure, it is recommended to add a section at the rear part of the pipeline.
Based on actual operating practices, in our plant the devices are installed in front of the pump’s outlet valve; this is because after starting the pump it is necessary to check the pressure first before gradually opening the outlet valve, and this applies to centrifugal pumps
