The problem that the pressure gauge of the acid unloading pump must be equipped with a buffer tube involves the characteristics of the acid unloading pump and the principle of the pressure gauge. The acid unloading pump is a pump used to transport acid liquid. Its working principle is to press the liquid into the pump body through mechanical energy and then transport it out through the pipeline. Pressure gauges are used to measure the pressure of liquids in pipes.
As to whether the pressure gauge of the acid unloading pump needs to be equipped with a buffer tube, it is generally required. The function of the buffer tube is to stabilize the measurement reading of the pressure gauge and reduce the impact of pressure pulsations and pressure pulses on the pressure gauge. When the pump body is working, the pressure of the liquid in the pump will change with the working conditions of the pump. Without a buffer tube, the pressure pulsation of the liquid will directly act on the pressure gauge, resulting in inaccurate measurement readings.
The buffer tube can stabilize the pressure and reduce the pressure pulsation amplitude by increasing the volume of the pipeline and reducing the resistance of the pipeline. It is usually a pipe or container with a larger volume and larger diameter, connected to an acid unloading pump and a pressure gauge. When the pump works, the liquid first enters the buffer tube, balances the pressure with the air in the tube, and then is transferred to the pressure gauge, thereby measuring the pressure smoothly.
Therefore, based on the working characteristics of the acid unloading pump and the principle of the pressure gauge, it is generally recommended that the acid unloading pump pressure gauge be equipped with a buffer tube to ensure the accuracy and stability of pressure measurement. However, whether a buffer tube needs to be installed depends on the specific working conditions and actual conditions. It is recommended to consult professionals before use or make a selection based on relevant design specifications.
