Q: Fix a false SUPOR electric pressure cooker E4 fault, after inspection, the pressure switch is not in good contact. Replacement repair, but do not know how to adjust, worry about not repair to the original machine state will explode! Ask the heroes what coup adjustment!!!: E4 pressure switch failure 1. pressure switch contact pressure is lower than 2. 0.04MP wet oxidation is controlled for the first case the oxidation processing clean; second cases had to adjust the pressure switch, the method is as follows: adjustment method of pressure cooker electric pressure switch has two kinds of methods, 1. have pressure gauge: adding an appropriate amount of water into the pot. Cover the pot boil, remove the pressure relief valve on the pressure gauge, such as meter readings to 0.068MP adjust the pressure switch to just disconnect the fixed with glue adjustment screw. 2. have no pressure gauge, do not remove the pressure relief valve, the pressure relief valve to the maximum, so just began to leak, immediately adjust the pressure switch to jump, then clockwise to spin again a little bit on the line. Remember to screw the screws with glue.

Q: What is the actual value of the pressure gauge mounted on the pressure vessel?: The pressure indicated by the pressure gauge is the table pressure, and the absolute pressure should be the indication of the pressure of the watch, plus an atmospheric pressure.

Q: What's the effect of the rubber plug at the top of the shock gauge? What's the effect of not cutting off?: The role of the rubber plug at the top of the shock pressure gauge:Rubber block is to prevent silicone oil (glycerin) leakage, the pressure inside the oil is filled with silicone oil (glycerin).Rubber stoppers, sometimes called safety plugs, leak protection, such as excessive internal pressure, plug will pop up, so that the glass is not easy to break.After the pressure gauge is installed, a small hole should be inserted into the rubber to make it connect with the atmosphere, otherwise it will affect the measuring accuracy.Vibration proof pressure gauge suitable for vibration occasions. Silicone oil is resistant to low temperature, glycerol is seismic effect, can make the measurement more accurate, and prolong the service life.The effect of no cuts: high pressure gauges are no problem. It's best to cut off or poke a small hole at low pressure.

Q: What do you think of the air conditioner liquid pressure gauge? How much pressure does it add?: You find a Fo and ask the not good.

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 general pressure gauge because it is made of copper and the spring tube welding soldering, the temperature of the medium and the environment must be less than 70 degrees.If more than 70 of soldering come loose, instrument damage (medium leakage).Not only is the problem of uncertainty, the instrument will certainly be damaged, there are security risks!

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: What is the principle of setting the root valve of the pressure gauge? Which gauges need to set the root valve? Which pressure gauges do not need to set the root valve?: First, local pressure gauges (in the PID diagram of a component named PG) installation interface are flange, flange with general HG/T20615-2009 DN20, the minimum pressure rating to Class300, Class300 is higher than that of no special requirements and process piping class agreement. Flange pressure rating less than or equal to Class600 when using the RF process, the pressure level with RJ CLASS600. In the process of vertical pipe on the diaphragm type pressure gauge will require the use of a 90 degree bend flange pressure gauge of the nozzle surface into the vertical flange, and pipe insulation shall not collide, and the vertical direction for bolt and nut construction space. 3. outside the flange surface, within the flange 150mm, set aside the space required for the long 700mm instrument installation. Two, the general pressure transmitter pressure transmitter (in the PID diagram of a component named PT) installation interface are flange, flange with HG/T20615-2009 DN20, the minimum pressure rating to Class300, Class300 is higher than that of no special requirements and process piping class agreement. Flange pressure rating less than or equal to Class600 when using RF process, pressure rating >Class600 with RJ. Single flange pressure transmitter, flange nozzle adopts HG/T20615-2009 DN50, minimum pressure level is Class300, higher than Class300, no special requirements, and process piping level. Threaded interface flange pressure rating less than or equal to CLASS600 with RF when suddenly face we installed on the pressure gauge with the cut-off valve with DN15;

Q: Why isn't the pressure meter back to zero?: If the new watch has air in it, it should be let out, and the specific reference manual. The old watch says the watch is out of order.

Q: What are the common measuring ranges of pressure gauges?: 0.25mp, 0.6mp, 1.0mp, 1.6mp, 2.0MP, 2.5MP and so on. In order to ensure that the elastic element can work reliably in the safety range of the elastic deformation, the pressure gauge range is selected not only according to the measured pressure, but also should consider the measured pressure change rate, the range need to leave enough room for. When measuring the steady pressure, the maximum working pressure shall not exceed 2/3 of the measuring range; the pulsating pressure shall be measured; the maximum working pressure shall not exceed 1/2 of the measuring range; when measuring the high pressure, the maximum working pressure shall not exceed the 3/5 of the measuring range. In order to ensure the accuracy of measurement, the minimum operating pressure should not be less than 1/3 of the measuring range. According to this principle, according to the measured maximum pressure to calculate a value, from the pressure gauge product catalog select a little larger than the measurement range.The pressure gauge is divided into vacuum meter, pressure vacuum meter, micro pressure meter, low pressure meter, middle pressure meter and high voltage meter according to its measuring range. Used to measure the atmospheric pressure is less than the pressure value of the vacuum gauge; pressure vacuum gauge used to measure the atmospheric pressure is larger than the pressure value; micro pressure gauge for measuring the pressure value is less than 60000 Pa; low voltage meter for measuring 0~6MPa value of pressure; pressure meter for measuring 10~60MPa value of pressure; pressure gauge for measuring the pressure value of more than 100MPa.

Q: Because our company is currently using the electric contact pressure gauge, a year or so down, the scene will always appear or big or small problems, I would like to ask the current market can buy a table, which a few do better? ThanksIn addition the seismic electric contact pressure gauge? What's the oil spill?: There are many brands, the main thing is to see whether the standard, general standards are ok. In accordance with the requirements of its load, the standard requirements of the number of off and on 30 thousand times. Regular manufacturers of products usually meet this requirement, quality is generally ok.Use:Common electric contact pressure gauges are suitable for measuring the pressure of copper and copper alloys without corrosive gases and liquids.The common electric contact pressure gauge can be made by connecting with the isolator (diaphragm body) to make the electric contact diaphragm pressure gauge. It is suitable for measuring the pressure of corrosive, high viscosity and Yi Jiejing medium.
