Q:The pressure gauge 0.1 stands for a few kilograms of pressure

Look at the range of your pressure gauge. If the measuring range is 0-1Mpa, then the 0.1 is 1 kilograms force

Q:How to choose a pressure gauge?

Maximum pressure (range of measurement)?Dial diameter?Connection mode?Medium condition? (corrosion, viscosity, heat, etc)Work environment? (vibration, pulsation, high temperature, high pressure, overpressure, etc.)Other special requirements (material, protection, heat dissipation, damping, etc.)

Q:What is the green area of the pressure gauge on the extinguisher?

The green pressure is normal, you can use it. When you get to the red zone, the pressure is too low to be used properly. It needs to be inflated. Just like the red light

Q:How to check the fire valve pressure gauge as normal?

The pointer is normal in the green area!"Building regulations": hydrant mouth pressure should not be greater than 0.8MPa; the water pressure is not greater than 0.5MPa; the "high regulation": the building height of not more than 100 meters, the most unfavorable pressure should not be less than 0.07MPa; more than 100 meters should not be less than 0.15MPa; the water gun full water column general building should not be less than 7 meters, a and B class of workshop, more than 4 layers of workshop and warehouse, and high-rise building multi-storey buildings and buildings more than 6 storeys height of not more than 100 meters should not be less than 10 meters, high-rise buildings should not be less than 13 metres.Spray system is: the worst point of the system, the work pressure should not be less than 0.05MPaSome people love to see the fire pump room pressure, the pressure must be large, the requirements are not less than those of numerical pressure above the highest point on the line, a building with a fire hydrant with a pressure gauge, you see that the pressure gauge on the line. Spray, you go to the top end of the test water pressure gauge on the line.

Q:What do you think of the pressure gauge for portable pressure storage ABC dry powder extinguisher?

1. There are three zones on the pressure gauge: Green Zone, red zone and yellow area2, the green zone is normal pressure; red zone is under pressure; yellow zone is the pressure is too large, should pay attention to.

Q:Drese D800 inverter and a remote pressure gauge how how to set the constant pressure connection

Structure principle:The resistance remote pressure gauge consists of a spring tube, a pressure gauge, a slide wire, a resistance transmitter, etc.. The function of the mechanical part of the pressure gauge is similar to that of the general Bourdon tube pressure gauge. Because the resistance transmitter system is arranged on the gear drive, therefore, when the fan gear shaft gear transmission mechanism of deflection, rotating arm resistance transmitter (brush) corresponding to the deflection due to sliding on the resistor, brush, change makes change transform the measured pressure value of the resistance value, and to two meters, to indicate the value of reading. At the same time, the primary instrument also indicates the corresponding pressure value.Turn left and turn right |?Wiring method:Open the box pressure on the right side of the table, you can see with three terminals 2, 3, 1, three respectively, the corresponding terminal is connected to the inverter control board of the V+, AI, 0V, and 0V in the inverter control board resistor terminal is connected in series with a 400 ohm 2 Watt (due to modifications, far from the pressure gauge can only receive less than 6 volt voltage power supply, and our frequency is 10 volt power supply, so in a series resistor in the circuit).Following chart:Turn left and turn right |The frequency converter is set as an external terminal and the given signal is on the line. Specific requirements, on-site tuning.

Q:The role of a pressure gauge

The action is used to measure and indicate the magnitude of the pressure within the pressure product. Pressure products, if there is no pressure gauge, or pressure gauge fails, the pressure product pressure can not be expressed, thereby directly endangering safety. The pressure product is equipped with a sensitive and accurate pressure gauge, and the operator can correctly operate the pressure product with the pressure gauge to ensure safe and economical operation.The pressure gauge can accurately indicate the pressure of the steam in the pressure product. The operator can adjust the heating degree of the product according to the indicated value of the pressure gauge to ensure the safety of the gas supply and the safety of the pressure product.

Q:The indicator of the extinguisher pressure gauge points to green, indicating whether the extinguisher pressure is normal or not?

Green indicates normal pressure; yellow indicates lack of pressure; please note that red indicates a severe lack of pressure

Q:Why does the internal surface of the pressure gauge contain oil?

In the pressure inside the shell injection liquid, usually oil. Liquid can play a strong buffering effect is obvious, so it can reduce the fluctuation / external vibration influence, caused by the pressure measurement reading. Through to the table filled with oil, but also on the machine parts for lubrication, while extending the instrument the service life of the pressure gauge. General pressure gauge is more expensive than ordinary. I will be in the company to purchase this kind of accessories. So understanding. Please refer to.

Q:What's the difference between the pressure gauge and the oil?

After oil is banned, it can be used to measure explosion, crystallization, solidification, liquid or gas that corrode copper and copper alloys
