- Q:How to connect the household air conditioner pressure gauge?
- 1) check the temperature and condensation of the liquid supply pipe and the return air pipe. Start the air conditioning operation 20min in the cooling case, if the outdoor unit valve and return pipe of condensation, touch the return pipe temperature was lower than the liquid supply tube temperature of the refrigerant in the system that is sufficient, the normal operation of air conditioning. One of the following circumstances, is that: the lack of refrigeration liquid supply tube condensation return pipe without dew; the liquid supply pipe and a liquid supply tube frosting; no dew public cold, back to the trachea is cool; the liquid supply pipe and gas tubes are not cool. (2) measure the pressure at the return valve. The pressure gauge is connected to the liquid air pressure angle valve, low pressure measured during operation, under normal circumstances, when the environment temperature is 30 degrees Celsius, low pressure cooling operation for 0.45~0.55Mpa heat pump type air conditioner should be 1.8Mpa in the heating operation, if less than the pressure, the shortage of refrigerant. The lower the pressure, the greater the leakage. If no pressure, then the refrigerant has leaked.(3) nitrogen pressure (filling 1.5Mpa nitrogen), four joint observation of two connecting pipes, gas valve stem, part of the liquid inlet and whether the oil spill that traces of oil.(4) use the tester to find out the general part of the leak, and then spread it on soapy water. If there is a bubble, it is the leak point.(5) the leak detection of the indoor unit and the connecting pipe of the heat pump type air conditioner shall be carried out under the condition of heating operation, because the inspected part is in a high pressure state at this time, and it is easier to find the leak point.
- Q:The water remote pressure gauge hands swing frequently do?
- 1, pointer rotation slow or jitterReason:1, the transmission parts of the clearance is too small, the transmission is not flexible, increase the gap, or add a little Watch Oil2, moving parts between the active parts of fouling, transmission is not working, cleaning, rust removal, in addition to dirt or replacement transmission3, the free end and connecting rod connection is not flexible, adjust the connection mode until flexible4, the pointer with the dial, table cover friction, correct the pointer, thicken the glass lining below2, the needle rotation is not smoothReason:1 、 the sector gear tilts to correct or replace the gear2, the needle axis bending, straightening needle axis3, plywood bending, correcting the flatness of plywood4, the pillar tilts, causes the upper and lower plywood not to parallel, correct the strut, the addition and subtraction washer, causes the splint parallel3, pointer jitter bigReason:1, measured medium pressure fluctuations, close the valve opening2, the gear is not good, adjust the gear with the state3, the needle sleeve and shaft coordination is not good, adjust repair pointer sleeve and shaft clearance gap
- 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:If the pressure gauge of the fire extinguisher is damaged and the interface of the pressure gauge is broken, will the fire extinguisher leak?
- The bottle body collision, deformation and cracking damage of nozzle nozzle is not to use the fire extinguisher pressure gauge in the red zone under voltage, need maintenance, seal damaged also need maintenance, depression
- Q:Vacuum table refers to the vacuum or pressure gauge?
- In fact, the vacuum meter, as the name suggests, is the reading of the vacuum. Here's a brief look at all the pressures:G P (table): pressure from pressure gauge read, it is the relative pressure by the atmospheric pressure as the benchmark value.Absolute pressure P (absolute): the actual pressure value based on absolute vacuum.The relationship between the absolute pressure gauge,P (absolute) =P (atmospheric pressure) +P (table)If the P (must) <P (atmospheric pressure), P (table) = - (P - P, the atmospheric pressure is lower than the vast) pressure gauge called vacuum. The higher the vacuum, the smaller the pressure.
- Q:Working principle of electric contact pressure gauge
- The work principle is very simpleIt uses sliding resistors to control the switchThe current signal is outgoing
- Q:Static pressure pipe pile construction, pile machine pressure meter reading how to convert to KN
- Static pressure pipe pile construction, the pile machine pressure meter reflects the horizontal bar pressure value (MPa), and the relationship between its pressure and pressure (KN) is related to the parameters of each cylinder.Hydraulic press pile machine press force and pressure meter reading conversion type is as follows:F=2PS+GType: F--------- press in force;P--------- pressure meter reading;S--------- press down the piston area of the cylinder;G--------- chucks, cylinders, plungers, and three weights of the pile driver
- Q:What's on the pressure gauge or something on the barometer? Which one told me?
- Bar is a unit of pressure 1bar=100000, Pascal, and another one of our common KGF is almost 1:1.PSE I guess you're wrong. It should be psi. It's the British unit of pressure. It's basically not used in countries with SI units
- 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:The difference between yn and YTN pressure gauges
- But each company provides the model is not the same, the functions are the same.
