pressure gaugeSuitable for measuring the pressure of corrosive, high viscosity, easily crystallizing, solidifying, high-temperature liquids, gases, or granular solid media, as well as situations where it is necessary to avoid direct entry of the measuring medium into the diaphragm pressure gauge, prevent sediment accumulation, and be easy to clean. Pressure gauges are mainly used in industrial sectors such as petroleum, chemical, synthetic fiber, dyeing, pharmaceuticals, and alkali food production.
The working principle of a pressure gauge when measuring the pressure of a medium is to set an isolation device on the periphery of the pressure gauge. The pressure of the medium will be transmitted to the internal pressure gauge through the sealing liquid, and the indicated value will be obtained. The characteristic of a pressure gauge is to use a medium isolation method for operation. The pressure gauge mainly consists of the pressure gauge itself and a specialized isolation device.
Pressure gauges have good anti vibration performance, especially suitable for working environments with mechanical vibration and medium pulsation. Pressure gauges can measure the pressure of liquids, gases, vapors, and other media that are non explosive, non crystalline, non solidifying, and do not corrode copper alloys.
pressure gaugePrecautions for use and maintenance:
1、 The precautions for use are as follows:
1. When using, slowly open the valve to gradually increase the pressure to the working position. If the valve is suddenly opened, such as when the pressure is out of control and exceeds the measurement limit, it will cause the spring tube to be damaged, deformed, or cause the teeth of the fan to detach, resulting in the instrument losing its function.
2. After use, the pressure should be slowly released and the pointer should not be suddenly dropped to zero position. This will cause the pointer to hit the disc stop pin, bending or even breaking the pointer.
2、 Maintenance Attention
1. Instruments should be calibrated or repaired according to the prescribed requirements.
2. The dismantled instrument should be stored in a dust-proof, dry, and non corrosive environment.
