Q:What do you think of the air conditioner liquid pressure gauge? How much pressure does it add?: The number corresponding to the pressure in the fluorine 22 pressure gauge refers to the evaporation temperature of fluorine 22 under the corresponding pressure. Any Freon 22 air conditioner operating in a refrigeration environment, the ambient temperature of 25 degrees to 45 degrees, the pressure should be 0.45-----0.6MPa.Outside the red circle, -30 to 350LB/IN2, this is the British unit of force, and the inside is -0.1 to 2.5MPa, this is what we often say pressure, unit is MPa (MPa).Now the table is in the position of no pressure, that is to say, the table pointer is on the 0 bit. Under normal operating conditions of the air conditioner, the meter should point to the 0.5MPa. 0.1MPa is approximately equal to 1.0197 kg / cm, 2 (kg/cm2) =0.987 atmospheric pressure (ATM), that is to say, the normal operating pressure of the air conditioner is 5.0985kg/cm2.

Q:What is the coefficient of error for the 2.5 grade pressure meter?: Table 2.5% of the range is an inaccurate thermometer

Q:Precision pressure gauge manufacturers can achieve precision 0.05 pressure gauges?: According to the JJG49-1999 spring tube precision pressure gauge and vacuum meter verification regulation, the accuracy degree of the pointer precision pressure gauge is:0.6, 0.4, 0.25, 0.1, 0.06The accuracy of the digital table is followed by 2.5, 1.6, 0.5, 0.4, 0.2, 0.1, 0.05

Q:What is a pressure gauge and how to make it?: 1. Pressure gaugeRefrigerant leakage is a common fault of air conditioning, refrigeration for dose adequacy of detection system, used to the pressure gauge, pressure gauge is a commonly used detection tool of freon refrigeration system, its shell diameter from 60mm to 250mm, a variety of specifications, suitable for air conditioner refrigeration system using a vacuum pressure gauge range to -0.1mpa 2.5MPa, as shown in figure 2-33,The pressure gauge and three way valve repair often supporting the use of clockwise three pass valve knob can make the valve repair, narrow hole, knob clockwise end, corresponding with the outdoor unit piping gas cut off, counterclockwise rotation knob, valve hole expansion, corresponding piping and outdoor group gas conduction, refrigeration system and the three way valve repair pressure gauge has been conducted, has nothing to do with the knob, together with three pass valve repair switch, can realize vacuum pumping, refrigerant filling and test pressure of the refrigeration system, etc..

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:The structure and working principle of the membrane box of the membrane pressure gauge?: The film box can not be fixed in the case, usually at the center of one of the diaphragm opening, as the inlet and fixed, then another diaphragm center is free end

Q:A 220V contactor, an intermediate relay, an electrode point pressure gauge, and a physical line diagram: A 220V contactor, an intermediate relay, an electrode point pressure gauge, and a physical line diagram are as follows:Turn left and turn right |This method is the pressure drop, the NC normally closed contacts closed, relay pull in, contactor also pull in, the load will workL is FireWire, N is zero line, 13 and 14 are relay coils, A1 and A2 are contactor coils, and 3 red ones are power lines.

Q:I just bought the pressure gauge. I don't want to look at it. Please tell me which expert to take a look at it. My car says front wheel 210kpa rear wheel 240kpa!!! We look at this table, where is the 210kpa ah, I'm afraid the wrong wrong, ha ha, help!! On the left is the watch just bought, and the right one with the watch on the compressor Are these two units the same?: First look at the pressure gauge pointer is in the zero state, and then the dust cap filled holes removed, the barometer component and the air charging docking with connectors, and then press the direction vertical air charging, you can display the numerical pressure gauge reading.

Q:How to control three-phase motor with electric contact pressure gauge: Electric contact pressure gauges - control intermediate relays (or electronic switches) - - control AC contactors - in the control motors

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?: I wonder what the allowable error of your watch is,I'll tell you a formula. You can count it yourselfThe allowable error range of instrument / X100%, the result is that you remove the back% of the watch precision to achieve. Then you can choose from the value of a small worth recently. (if you count up to 0.6, you can choose 0.5 of the table.)The level of instrument accuracy stipulated by China is 0.005,0.02,0.05,0.1,0.2,0.35,0.5,1.0,1.5,2.5,4.0., among which 0.5-4.0 is a common industrial instrumentIf it's not clear, leave a message for me
