- Q: Where is the pressure gauge checked?
- The local quality and Technical Supervision Bureau's Institute of measurement and measurement.
- Q: Function of electric contact pressure gauge
- The instrument comprises a measuring system, an indicating system, an outer shell, a magnetic auxiliary electric contact device, an upper and lower adjusting device and a junction box. When the measured medium pressure through the guide part into the measuring element, in which the pressure produces the corresponding displacement measuring element free end through the connecting rod drives the gear transmission mechanism, resulting in the dial on indication of the measured medium pressure value. At the same time, the instrument pointer drives the upper and lower limit movable arm and the set pointer (upper and lower limit) contacts to be disconnected or closed, so that the control circuit can be switched off so as to achieve the purpose of automatic control or sending letters to alarm.In general, the instrument can be used for automatic control or transmitting alarm by measuring and controlling the pressure system of the medium (or relay), which is used in conjunction with the corresponding electrical appliances (such as relays, contactors, etc.).
- Q: Want to buy a pressure gauge, but do not know how to determine the pressure gauge model, you can only measure the size of the dial and then the size of the thread, there is no master pointing out the pressure gauge model specifications?
- The general pressure gauge, such as Y60, Y100, Y150, behind the figure is the dial diameter, if Y is connected to YX, the screw axial (Y radial), also is the specified range, thread size (usually GB)
- Q: What are the types of pressure gauges? What is the principle of each? Who has other information about industrial hardware? Give it to me -- thank you
- The oil pressure gauge is the vibration proof pressure gauge (the main role is to earthquake, the pointer swing damping effect)The pressure gauge is divided into four kinds according to the sensor: Bourdon tube pressure gauge, diaphragm pressure gauge, diaphragm pressure gauge and diaphragm pressure gauge.Basically, the spring element is different. The spring tube is used to indicate the pressure through the deformation of the 270 degree C tube;The diaphragm drives the pointer through a single diaphragm;The film box is equivalent to the two diaphragm welded together, just like a box, only for measuring gas.The diaphragm is a combination of diaphragm and spring tube.
- Q: Is the gauge thread metric or English?
- In domestic engineering, gauges generally use metric threads, such as M20*1.5, with M14*1.5 or M10*1 threads on some small gauges. In addition, some items may use inch threads, such as G1/2, small table diameter, G1/4 or G1/8. The above two are straight thread, is the end seal, installation needs to choose different gaskets according to different conditions. In addition, some use NPT thread by joint venture or foreign patent project, commonly used is 1/2 NPT, a small table size with 1/4 "NPT" NPT, 1/8, rarely used this is American Standard thread cone type buckle. This thread by thread sealing, without gasket. Domestic often winding Teflon belt, because the domestic NPT fastener processing accuracy is not high. The commonly used table diameter is 100150mm, and the small caliber is below 63mm.
- Q: Detailed explanation of working principle of Bourdon tube pressure gauge
- The working principle of the spring tube type pressure gauge is spring tube; under the action of pressure, the free end displacement, the displacement of the rod drives the transmission amplification mechanism, the pointer deflection, and indicate the pressure value on the scale.Bourdon tube pressure gauge is mainly composed of a threaded joint holder, spring tube, rod, screw, gear sector, small gear, hairspring, pointer, upper and lower clamping plate, dial, case, shell etc..The function of each component in the drive amplifier mechanism:(L) pull rod - transfer the displacement of the free end of the spring tube to the sector gear;(2) the sector gear converts the line displacement to angular displacement and then passes it to the pinion and has an amplification effect;(3) the pinion drives the coaxial pointer to rotate, indicating the measured pressure on the dial;(4) - the gossamer fan gear and small gear tooth profile keep one-way contact clearance contact two gear, in order to reduce the return difference;(5) adjusting the screw - changing the position of the adjusting screw can change the length of the short arm of the sector gear, so as to change the drive ratio;(6) the upper and lower clamping plates fix the components together to form a set of transmission mechanisms.The drive mechanism, also known as the movement, is the heart of the pressure gauge. Its function is to enlarge the displacement of the free end of the spring tube so as to achieve the purpose of easy reading.
- Q: Do not understand ah, general repair air conditioning is to see that MPa ah, this temperature is what temperature ah? What's the saturation temperature? Oh, thank you
- In order to observe whether the air conditioner or refrigerator is running properly, the pressure of the refrigerant and the corresponding temperature is one of the parameters.
- Q: 250MPa calendar force, 150MPa verification point when the step-up is 148MPa, when the buck is 149MPa, please tell me how to calculate the value of error, return error is how to count? Thank you
- According to JJG52-1999, Bourdon tube, general pressure gauge, pressure vacuum gauge and vacuum gauge, 5.3.3.5, return error:For the same test point, the difference between the indication value after tapping the watch case at the step-up (or step-down) and the buck (or boost) testThe return error is the absolute value
- Q: What kind of pressure gauges do you need for repairing refrigerators?
- Maintenance of refrigerators requires at least 3 pieces of pressure gauge, 2 pieces, 2.4 kilograms, a piece of 1.5. The refrigerator low pressure gauge can not measure high pressure.1. Maintenance of pressure gauges for refrigerators is a necessary tool for maintenance.2, through the high-low pressure to determine the operation of air conditioning.3. Vacuum system and evaporation pressure are determined by observing low pressure meter when pumping vacuum and charging refrigerant.4. Watch the high and low pressure meter at the same time when the refrigerator is running, and pass the evaporation pressure of the low pressure meter.
- Q: The role of a pressure gauge
- As the name suggests, it is to measure the pressure, welding need to ensure adequate flow of gas protection, sufficient flow is the premise of sufficient pressure in the tank, pressure gauge is to show the pressure inside the tank is enough
