1/ 8 npt oil pressure gauge
What is 1 /8 npt oil pressure gauge?The structure of the oil pressure gauge itself is not very complicated, but the original structure is also very precise.
1. The function of the buffer structure in the oil pressure gauge (main protective function)
What is the buffer tube of the oil pressure gauge? The buffer tube of the oil pressure gauge is also called the pressure gauge elbow or the condenser tube. The impact of the spring tube can be reduced, and the temperature of the measured medium can be reduced, which has a good protective effect on the oil pressure gauge. Under normal conditions, the buffer structure of the oil pressure gauge is mainly O-shaped, U-shaped, etc.; there are many commonly used models. In industrial production, the pipeline is required to measure its "formed pressure" for fluid requirements, so there are special requirements for the material it is made of.
2. The role of the table bend design in the oil pressure gauge (the role of heat dissipation and shock resistance)
Generally speaking, professional oil pressure gauges will have a curved surface. The goal of the curved surface of the oil pressure gauge is to protect the internal transmission mechanism of the watch from the medium temperature and medium corrosiveness. If the medium is corrosive, a pressure gauge bend must be added, and the condensing bend of the pressure gauge is generally referred to as the pressure gauge buffer pipe. It mainly has the function of reducing vibration and blow, and can also play the role of heat dissipation to protect the oil pressure gauge and reduce the deviation of the measurement results affected by the temperature of the oil pressure gauge. There are also damping screws designed at the orifice of some oil pressure gauges, the principle of which is to reduce and buffer by reducing the fluid area.
