- Q:How to adjust the upper and lower limits of the upper and lower limit of the electric contact pressure gauge?
- There is an adjusting screw in the pressure gauge, changing the position of the screw can realize the adjustment of the range and the range of the pressure gauge. The upper and lower limit should be set before you according to your needs
- Q:What is the pressure gauge cock
- The pressure gauge is a pressure gauge cock, special three way cock. The characteristic is that when the pressure gauge pipe is flushed, the medium is not allowed to enter the pressure gauge, and the medium can be discharged directly. This is to protect the form of pressure gauge design.
- 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:Is the boiler pressure gauge mandatory?
- Is. Moreover, there are six months a year, some of which are examined once a year
- Q:Measurement data, installed in the normal position, do not know whether to reverse installation, please professionals to help answer! Thank you Urgently!
- Yes, the location does not affect the accuracy of the data
- Q:What kind of pressure gauges do you need for repairing refrigerators?
- Maintenance of refrigerator needs with a minimum of 3 pressure gauge, 2 pieces of 2.4 kg, a 1.5 meter, pressure for a 6 tube 20-30 cm for the table header and good expansion valve, bell, head table valve is connected with the need to use teflon tape, tied to the wire head on and valve connection table header all together, even after looking for a 8 to 6 of the copper pipe welding, a set of tools to complete, maintenance of refrigerators need tools to cut, expander, welding, solder, sealing device, electronic scales, pressure gauge, fluoride bottles, evacuation tools, it is best to prepare some brass 6 and 8.
- 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:What are the problems with the pressure meter?What are the good solutions to these problems in the pressure gauge?
- As everyone knows the main parts are made by pressure gauge, Bourdon tube, joint movement, the working principle of instruments is deformed by a spring pipe core (gear fan gear and drives the pointer in the dial Center) version of the show on the measured medium pressure, pressure gauge welding mainly lead zinc silver welding, argon welding. Arc welding, special welding and so on, the instrument clarinet is 100 thousand times the normal working pressure gauge the problems in the process of using zhongchanghui,1. instrument pointer because the measured medium instantaneous pulse increases, the pointer to the file below,2. instrument pointer, after the pipeline or equipment is unloaded, it will not be zero,3. additionally, the instrument fan teeth will wear out after working for a period of time,The movement of the instrument is the heart part of the pressure gauge. More than 80% of the instrument damage is caused by the damage of the movement, and the instrument can not be used. Now, I solve the problem of instrument jump by adding the spacing nail between the existing movement,4. plus isolation chip to solve the problem of instrument not return to zero5., from the fan type tooth widening, to solve the instrument contact surface, wear resistance, in order to achieve service life extension function
- Q:How about the model of seismic pressure gauge?
- There is a general proof letter "N"
- Q:What does the pressure gauge 1% mean?
- Accuracy 1% means the full scale error range of this pressure meter is + 1%.Precision pressure gauge, is expressed as a percentage of the allowable error range of the pressure gauge, generally divided into 0.5, 1, 1.5, 2, 2.5, 3, 4 and seven grades (boiler not 3 and 4), the smaller the value, the higher the accuracy. For example, the dial range 0 ~ 2.5 MPa 2.5 precision pressure gauge, it is shown the allowable error of pointer pressure between the actual pressure value and the measured value of the medium, not more than 2.5MPa * 2.5%= + 0.0625 MPa; when the pressure gauge pressure is 0.8MPa, the actual pressure between 0.7375 ~ 0.862 5MPa.Thus, the actual error of the pressure gauge not only relates to the accuracy, but also relates to the measuring range of the pressure gauge.When the measuring range is the same, the higher the accuracy (i.e. the smaller the number), the smaller the allowable error of the pressure gauge.When the accuracy is the same, the greater the measuring range, the greater the error of the pressure gauge.It is divided by the percentage of allowable error to dial scale value, and the greater the accuracy grade, the bigger the error limit of the dial scale. The greater the measuring range of the pressure gauge, the same accuracy level of the pressure gauge, the absolute value of the pressure measurement it allows, the greater the error.
