Beer equipment manufacturer beer equipment pressure knowledge of how much you know

beer equipment manufacturer will take you to analyze beer equipment pressure gauge of the relevant knowledge, to realize the pressure gauge is based on the atmospheric pressure, instruments used to measure below or above atmospheric pressure. In the process of industrial process control and technical measurement, due to their high mechanical strength, elastic sensitive elements is convenient for production, are increasingly using mechanical pressure gauge.

mechanical pressure gauge in the elastic sensitive element would occur with the change of stress and elastic deformation. Mechanical pressure gauge use sensitive components, such as the spring tube, the diaphragm, corrugated tube and corrugated pipe, and a corresponding classification was carried out. Measured pressure is usually considered a relative pressure. Usually, the relative point is selected as the atmospheric pressure. The elastic deformation of elastic element under the action of medium pressure by pressure gauge gear transmission mechanism is amplified, pressure gauge will show the relative value of relative to atmospheric pressure.
pointer display measured pressure value, within the scope of dial indicator are generally for 270. Pressure gauge according to its measuring accuracy can be divided into pure pressure gauge and ordinary pressure gauge. The essence of pressure gauge and measurement precision of 0. 1, 0. 16 degrees, 0. 25 degrees, 0. 4 degrees; The measuring accuracy of general pressure gauge 1 respectively. 0 and 1. 6, 2. 5 and 40. Pressure gauge according to the different standards can be divided into normal pressure to pressure. Pressure gauge, the relative pressure gauge, stainless steel pressure gauge, differential pressure tables.
general pressure gauge based on atmospheric pressure; The relative pressure gauge based on zero relative pressure. Differential pressure gauge measuring the difference between the two measured pressure.
pressure gauge according to its measuring range is divided into the vacuum gauge, vacuum gauge, pressure gauge, the low pressure table, table and high pressure table. Vacuum pressure gauge for measuring the subatmospheric pressure value; Pressure gauge is used to measure the pressure value of below and above atmospheric pressure; The micro pressure gauge is used to measure the pressure value of less than 60000 pa; The low pressure table is used to measure the pressure value of 0 to 6 MPa; Medium pressure table is used to measure the pressure value of 1060 mpa; High pressure table is used to measure the pressure value of more than 100 mpa.
pressure gauge is divided into 25 kinds of patterns: pointer gauge and digital pressure gauge. Seismic pressure gauge shell made from fully sealed structure, shell filled with damping oil ( Most filled with silicone oil) 。 Due to its damping effect, it can be used to measure the working environment vibration or medium pressure ( Load) Pulse.
charged contact control switch of the pressure gauge can realize the alarm or control functions. With the remote transmission mechanism of the pressure gauge can provide the required electrical signals in industrial engineering.
the diaphragm gauge isolator can be used in the isolation diaphragm will be medium and instrument by isolation, by measuring with strong corrosion, high temperature and pressure and easy to be crystallized media.
pressure sensitive components are usually made of copper alloy, stainless steel or special materials. Bourdon tube ( Bourdon tube) Divided into C shape pipe, spiral pipe, spiral pipe, and other shapes. Often use cold hardening material tube, with high plasticity in annealing state, and in the pressure processing, after cold hardening and qualitative processing for high elasticity and strength. In spring tube under the action of the pressure in the cavity, the elasticity of the spring tube can be used to easily converts pressure spring tube free the elastic displacement. Spring tube measurement range is commonly 0. 1250MPa。
diaphragm is sensitive element with a wave of circular diaphragm, diaphragm itself is located between two flanges, or weld on the flange, or edge sandwiched between two flanges. One side of the diaphragm from the measured medium under pressure. In this way, small bending deformation produced by membrane can be used to indirectly measuring the pressure of medium. The size of the pointer indicated pressure. Compared with the bourdon tube, the diaphragm has higher heritability. Because the diaphragm around the edge, so the vibration resistance is better. Diaphragm table can achieve very high overpressure protection
the diaphragm can be covered with a protective layer, in order to improve corrosion resistance. Through the use of open flange, flushing, aperture and other measurement methods, the diaphragm gauge can be used for measuring high viscosity, dirt and crystallization medium. Diaphgram gauge pressure measurement range to 1600 pa2. 5MPa。 Bellows sensitive element is made up of two diaphragm for circular cross section of fasten together. Measuring the pressure of medium within the capsule of the cavity, and the deformation can be used to indirectly measure the pressure of the medium. Pressure value using a pointer display. Corrugated tube manometer is usually used to measure the micro pressure of the gas, and has a certain degree of overpressure protection. After stacking various sensitive components to the capsules, they will produce a lot of heritability and to measure low pressure.

the above of the beer equipment manufacturers belt you know is the equipment pressure analysis, pressure gauge, of course, should also be regular inspection and maintenance. Because in the use of a period of time and pressure, pressure gauge movement will inevitably deformation and wear and tear, and the pressure gauge will happen various fault and failure. In order to ensure the original accuracy and will not affect the value of the transfer, to replace it in time to ensure that the correct, safe and reliable.
