- Q: How does the fire pump pressure meter work?
- Fire pump pressure meter work:1, the fire pump outlet pipe pressure gauge (in the pipeline and pipeline pump lift check valve between the pump running only) to show the pressure value, to test the pump outlet pressure and pump running out of water.2. The pressure gauge on the fire main pipe acts as a check on the pressure of the fire system.3, the highest point of the fire pipe (that is, the most adverse point), the role of the pressure gauge to check the most unfavorable point, hydraulic pressure value.
- Q: Function of electric contact pressure gauge
- Function of electric contact pressure gauge:The utility model is used for measuring the positive and negative pressure of the gas and liquid medium which does not corrode copper and copper alloy, and sends out signals when the pressure reaches a predetermined value, and the control circuit is switched on to achieve the purpose of automatic control of the alarm.Electrical contact signal pin in electric contact pressure gauge device, a permanent magnet can be adjusted, can increase the contact force, speed up the contact action, so that the contact reliability, eliminating the arc, can effectively avoid the instrument working environment due to frequent vibration or medium pressure pulsation caused by contact off. Therefore, the electric contact pressure gauge has the advantages of reliable operation, long service life and large power of the contact switch.
- Q: How is the pressure gauge ABC divided?
- Instrument certification according to the location of the importance of varying degrees, generally divided into a, B, C three grades.A class is generally used in pressure control strict locations, requiring accurate instructions, is the focus of monitoring instruments, usually for an annual or semiannual inspection;Class B is generally used at locations where pressure control is more stringent and requires more accurate instructions. It is a general monitoring instrument, usually tested annually or two years;Class C is generally used in places where the pressure control is not strict and can be used as a reference value. It is a non monitoring instrument, usually tested for many years or replaced after failure;
- Q: What is the actual value of the pressure gauge mounted on the pressure vessel?
- The pressure indicated by the pressure gauge is the table pressure, and the absolute pressure should be the indication of the pressure of the watch, plus an atmospheric pressure.
- Q: What's the difference between a pressure gauge and a negative pressure meter?
- According to the type of pressure to be divided into negative pressure table, differential pressure gauge, positive pressure gauge, so the negative pressure gauge is only one kind of pressure gauge.Negative pressure meter measurement is relative to the local atmospheric pressure for negative pressure, negative pressure table, also known as vacuum pressure gauge, but conceptually there are some subtle differences, not here.If there is no special explanation, we generally say the pressure gauge defaults to the positive pressure meter.
- 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: What is the calibration cycle for the pressure gauge / thermometer / flowmeter? Is there a standard to check?
- Used as an enterprise, usually for one year unless required.
- Q: Set up a factory. May I ask what equipment you need to build a pressure gauge factory?
- Is the professional calibration equipment, you Baidu will know, I am Nanjing Wanda instrument factory. Hope to help you.
- Q: First, the water pump remote pressure gauge in the pipe without water, whether the pointer should refer to 0Second, when the inverter is not bad and does not work, whether the table of sliding resistance is bad, so that the frequency converter can not be induced without action. Thank you for your advice.
- The pressure gauge (English Name: pressure gauge) refers to the elastic element as the sensitive element, measuring and indicating higher than ambient pressure meter is widely used, it almost all the industrial processes and scientific research. In the heat pipe network, oil and gas transmission, water supply system, vehicle repair and maintenance shop, and other fields can be seen everywhere. Especially in the control and measurement process, because the elastic sensitive element of mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is widely used.
- 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.
