Why Should The Pressure Gauge Installed At The Pump Outlet Bend A Circle?

Why should the pressure gauge installed at the pump outlet bend a circle?

Today I will talk to you about a common, but often overlooked thing! I don’t know if you have noticed: When the pressure gauge is connected to the pipe, a bend should be added between the pressure gauge and the pipe connection. What is the reason for this?

In fact, the connection between the pressure gauge and the pipe is the pressure gauge bend (also referred to as the gauge bend), and the official name is the buffer tube. There are two types of pressure gauge bends: one is a circular bend and the other is a U-shaped bend.

The purpose of the pressure gauge bend is to protect the internal transmission mechanism of the gauge from the damage of the medium temperature and the corrosiveness of the medium. Generally, if the medium is corrosive to a certain degree, a pressure gauge bend must be installed. When the temperature of the medium is greater than 60℃, a pressure gauge bend must be installed. If the pressure gauge is installed on a clean drinking water system, no additional installation is required.

In addition, it has the function of reducing vibration and impact, and also has a certain heat dissipation effect on the higher temperature medium to protect the pressure gauge and reduce the temperature influence error of the pressure gauge. The damping screw at the orifice of some pressure gauge joints has a throttling buffer effect by reducing the flow area, which is mainly useful for medium pressure pulses.
