(Summary description)This article discusses the precautions for the installation of pressure gauges and pipelines in the pneumatic conveying system! First of all, we should know that the pneumatic conveying system uses pressurized gas (positive pressure or negative pressure) to convey the material to the designated place. Then there is a very important link in the pneumatic conveying system - pressure detection. There are many pressure testing or display instruments in the pneumatic conveying system, among which the simplest and most commonly used is the pressure gauge. So what should be paid attention to when installing the pressure gauge? This depends on the installation environment of the pressure gauge. 1. The connection between the pressure gauge and the conveying equipment. 2. Add an elbow between the pressure gauge and the pipe connection. 3. The pressure gauge is connected to the control box. 1. The connection between the pressure gauge and the conveying equipment. In pneumatic conveying systems, pressure gauges are usually connected directly to the conveying equipment. as the picture shows.   This is because the pneumatic conveying equipment in a pneumatic conveying system usually has a large volume. In each conveying process, the free space in the conveying equipment is relatively large, so that the pressure gauge is relatively isolated from the material. In addition, the conveying equipment needs to have an exhaust port, and it is more conducive to accurately measure the pressure by directly installing the pressure gauge. 2. When the pressure gauge is connected to the pipe, add an elbow between the pressure gauge and the pipe connection. Why?   The connection between the gauge and the pipe is the gauge elbow (also known as the gauge elbow), formally known as the buffer tube. There are two forms of pressure gauge bends: one is annular and the other is U-shaped.   The purpose of adding the pressure gauge bend is to protect the internal drive mechanism of the pressure gauge from being damaged by the medium temperature and corrosive medium. Usually, if the medium is corrosive to a certain extent, the pressure gauge must be bent, and when the medium temperature is greater than 60°C, the pressure gauge must be bent. If the pressure gauge is installed on a clean drinking water system, no additional installation is required. It also has the effect of reducing vibration and impact, and also has a certain heat dissipation effect on the medium with higher temperature, so as to protect the pressure gauge and reduce the influence error of the pressure gauge temperature. The damping screw at the orifice at the joint of some pressure gauges plays the role of throttling and buffering by reducing the flow area. The pressure gauge on the general gas tank is also connected in this way. 3. The pressure gauge is connected with the control box. The pressure gauge in the control box requires direct connection, and it is required to be horizontal and vertical during installation.   Of course, the connection outside the control box should depend on the specific installation location and measurement location. Choose the installation method according to the above two situations.
