- Q: What does "MPa" on the pressure gauge mean?
- Commonly used in engineering is MPa (MPa): 1MPa=1000000Pa.
- Q: In which industry does the pressure gauge use more?
- Iron and steel, smelting, hydraulic, residential, piping, electricity, machinery, heavy industry, chemical, petrochemical units, covering all walks of life
- Q: What is a back mounted pressure gauge and why is it called back loading?!
- It should be the axial pressure gauge
- Q: Why is the manifold pressure gauge called the manifold pressure gauge, not the air conditioning pressure gauge group?
- The manifold pressure gauge is called the manifold pressure meter, which means it can measure the pressure of a plurality of pipes, and the manifold is the meaning of the manifold;Turn left and turn right |Manifold pressure gauge structure as shown, mainly by the high pressure meter, low pressure table, high pressure manual valve, low pressure manual valve, valve body and 3 hose joints. High and low pressure meters are used to detect the pressure at the high and low side of the refrigeration system. Low pressure side pressure gauge is used to display the pressure, are also used to show the degree of vacuum, vacuum pressure reading range is 0~0.101MPa, graduated from the beginning of 0, shock process is not less than 0.42MPa; the pressure range of pressure meter to measure the high side from the beginning of 0, the range of not less than 0.211MPa.
- Q: It is better to explain in principle what parts are not resistant to heat What happens if you measure a high temperature medium? Is it just inaccurate or will there be parts damage?
- The definition of high temperature is uncertain. You can look at the parameters of the pressure gauge
- Q: What does "PV" and "SV" on the control meter of remote pressure gauges mean?
- 1 display settings and 1 display actual values.
- Q: If the plot pressure gauge 2.5MPA and the daily work range 1.23MPA-2.12MPA, what sort of pressure gauges should we choose?What are the methods of calculation?
- China's general industrial pressure meter is divided into 4 accuracy levels, in line with the JJG52-1999 "Bourdon tube general pressure gauge, pressure vacuum table and vacuum meter" verification regulations, the pressure table prepared by the allowable error. These 4 levels of accuracy are: 1, 1.6, 2.5, and 4. Allowable error (calculated according to the percentage of the upper limit of measurement) is 1%, 1.6%, 2.5%, 4%, respectively.China 2005 new digital pressure meter verification regulations promulgated and implemented, in line with JJG875-2005 "digital pressure gauge verification regulations.". The accuracy of the pressure is respectively 0.01%, 1.6%, 0.02%, 0.05%, 0.1%, 0.2%, 0.5%, 1%, and so on.
- Q: What are the main technical parameters in the selection of pressure gauges? Thanks
- The selection of the pressure gauge mainly refers to the use environment, measuring medium, accuracy, range and shape size, at the same time in line with international standards or corresponding national standards.
- Q: Which circle should I watch with R22 plus, and which lap should I watch with the additional 410A?
- Look at the same place! Just the pressure is different! R410A pressure is higher than R22! Look at the outermost black circle! R22 from 4.5 to 5Kgcm2. R410A added 7.5 to 8KG/cm2 is almost the same!! No matter what refrigerant is different, only the pressure will not change.
- Q: Are you talking about using a gold contact? I'm a small relay for 24V. Do you need a gold contact?Let's talk about it.
- No gold is necessary for contacts.1. The action of a contact on a pressure meter is equivalent to a switch used to conduct or disconnect the circuit. It does not require a power supply. The maximum operating voltage is 380V, and it can also be used for 220V or 24V (including AC and DC).2. Electric contact pressure gauge in the work process, will not contact in contact contact, due to voltage, spark will contact between the spark can burn contacts, lead oxide, so the electric contact pressure gauge work after a period of time will produce the phenomenon of bad contact, and can work normally after cleaning contact.3. In order to make the electrical contact work long time, it is important to note that the work power of the coil of the small relay in the back shall be controlled below 30W, otherwise it will burn up easily (contact power rating 30W).4. What material to choose contact is to consider comprehensively, choose pure gold or pure silver, only contact resistance is small, other aspects will not do.
