- Q:What will happen to the calibration process if the calibrator of the pressure gauge is not clean?
- Fluctuations resulting in inaccurate calibration of the pressure gauge.
- Q:Pressure gauges M20*1.5, M14*1.5 need to be equipped with DN how many valves, and pressure gauges, elbow and connector specifications, models
- There is a special pressure gauge switch. With M20 * 1.5, M14 * 1.5, it can be easily matched.
- Q:What does the red line on the dial of the pressure gauge stand for? Is the design pressure or the maximum pressure?
- There are no red lines on some dials. Where is the red line you mean?
- 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?
- Whether there is no breach is not important, mainly the pressure indicator in the yellow area, green area proved to have no drainage pressure, red zone without pressure or too small, yellow zone pressure is too large, in case of high temperature and so on, the explosion is more serious, green zone safety. Rubber hose fire equipment stores have sold 2-5 yuan, the inner layer has not split open, you can use, indoor storage extinguishers can not exceed 2 years, to overhaul once (pointer in the green zone should be detected), 1 years, 1, the most security testing.
- Q:How to choose the accuracy level of the standard pressure gauge when calibrating the industrial pressure meter with the standard pressure gauge? Can I use a stage 0.2, range 0 to 25MP?
- The general election results table to use than the calibrated meter high a range check table, table 2.5 the pressure should be 4MPa, 25MPa a lot.A general pressure gauge is a device that measures and indicates higher than ambient pressure by means of a spring tube as an elastic element. In the control and measurement process, the elastic sensitive element of mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is widely used. A pressure meter, a vacuum meter, and a pressure vacuum meter of the order of magnitude equal to or lower than 1, collectively referred to as a general pressure gauge.
- 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
- The pressure gauge common breakdown has following four points:1, the needle does not move. That is, when the pressure is raised, the indicator of the pressure gauge does not move.Cause analysis: Cock cock, not open; pressure gauge connection pipe or water pipe blockage; the pointer and the central shaft is loose or pointer stuck.2, pointer jitter.Cause analysis: hairspring damage; plug or trap local channel is blocked; both ends of a center shaft bending, two ends of the shaft rotation is not concentric.3, the pointer can not return to zero when there is no pressure.Analysis of reasons: spring tube permanent deformation, loss of flexibility; pointer and center axis loose or pointer stuck; plug, pressure gauge connecting pipe or water retaining pipe channel blocked.4 、 the instructions are incorrect and exceed the allowable error.Cause analysis: mainly due to the spring tube due to high temperature and overload or excessive deformation; gear wear loose; balance disorder; plug leakage.
- 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.
- I don't think it's necessary to use gold 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.Our company produces a variety of electric contact pressure meter, suitable for a variety of industrial and mining use, interested can go up to see.
- Q:How many degrees above is the high temperature pressure gauge?
- High temperature has two levels of meaning, on the one hand refers to the environmental temperature, on the one hand refers to the work medium temperature, the ambient temperature is generally more than 40-50 degrees, that is, high temperature table. Working medium temperature, because it can be installed radiator, the temperature is higher than 80 degrees, it belongs to the high temperature table.Moreover, the influence of the temperature of the high temperature table on the table is also divided according to the accuracy level of the table, and the higher the accuracy, the greater the impact
- Q:Which circle should I watch with R22 plus, and which lap should I watch with the additional 410A?
- The temperature of R22 looks at the red inner ring,The pressure of the R22 value corresponding to see the outer black value (35kg/cm - =3.5MPa is 10 times),The pressure values are all on the outermost ring, regardless of the medium;There are four kinds of media in the red circle and blue circle, which are the temperature of the corresponding medium under the same pressure.
