- Q: The electric contacts pressure gauge, electric contact is often the first contact is damaged, burned, the general use of the electrical contacts to control AC contactor, there is no way to prolong the service life, add a damping absorption of the original electric contacts at both ends can be? What should I do?
- 1, the electric contact pressure gauge in the allowable conditions, as far as possible can make the upper and lower limit a little larger.2, the electric contact pressure gauge on the pressure indicator fluctuations, that is, should be in the pressure pipe to increase damping, that is, increase the buffer, such as the installation of ring pipe, properly close the small valve.3, the electric contact pressure meter reduces the current through the electric contact, the effective method is the electrical connection point through the electronic amplifying circuit (uses the triode, IC) to drive the relay.4, the electric contact pressure meter reduces the power supply voltage of the electric contact, of course, the related relay also needs to be exchanged. The RC spark suppression element is connected to the electric contact.5, the electric contact pressure gauge uses the magnetic auxiliary type electric contact pressure gauge.6, electric contact pressure gauge is through magnetic force auxiliary contact torque increases the electrical contact, has relatively high electric contact pressure gauge contact power, because the magnetic effect on the electric contact pressure gauge can increase the contact force, accelerate the speed and make contact contact, reliable contact, can eliminate the arc, can avoid contact monometers due to frequent action of vibration or medium pressure fluctuations caused by contact.
- 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: See others welding, found that there are two pressure gauges on the cylinder, one is 0-0.3 range as if, and the other is 0-4 range, ask why, is it safety considerations or other reasons? thank
- 0-0.3MP is a low pressure meter, which is an oxygen pressure reducer. It converts the high-pressure oxygen into a uniform low-pressure oxygen through the knob handle to supply welding or cutting. 0.3MP's pressure is very common.0- 4MP is a high pressure oxygen meter. The oxygen bottle allows 15MP gas to be filled. This is the gas left in the cylinder at present, 4MP. High pressure makes gas cylinders fill more gas.
- 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 are the diaphragm materials for the diaphragm pressure gauge?
- Diaphragm pressure gauges are suitable for measuring the pressure or negative pressure of a variety of fluid media which are corrosive, non coagulated or non crystalline.The diaphragm gauge and corrosion resistance can be guaranteed by means of suitable and selected diaphragms, flanges, and gasket gaskets in contact with the measuring medium.Diaphragm material: 0Cr17Ni12Mo2 (316); Fu Jin (Cu30Ni70) Monel Hastelloy; gold; tantalum (H276C) (Ta) and fluorine plastic (F4).Gasket materials: nitrile rubber; fluorine rubber; silicone rubber and fluorine plastic.
- Q: Do not understand ah, general repair air conditioning is to see that MPa ah, this temperature is what temperature ah? What's the saturation temperature? Oh, thank you
- There are two main air conditioning test pressure, a condenser outlet pressure, a back pressure evaporator, the refrigerant from the condenser outlet state is liquid, so the pipe is fine, the refrigerant from the evaporator outlet state is gaseous, so thick pipe.Repair air-conditioning generally look at these temperatures:1. indoor air outlet temperature, used to determine whether the normal air conditioning.2., the condenser outlet temperature, used to determine whether the condensation is too cold, the greater the supercooling, the better.3., the evaporator outlet temperature, used to determine whether the gas back overheating, overheating is too large, small is not good.Notice that the outdoor unit is a condenser when it is cooled and the chamber is an evaporator.Saturation temperature is the temperature in which a liquid evaporates and a vapor condenses in a dynamic equilibrium state, i.e., a saturated state. Saturation temperature is related to pressure.
- Q: What are the problems with the pressure meter?What are the good solutions to these problems in the pressure gauge?
- Summarize the common faults and causes the pressure gauge, in the operation of only the exchange, because of different brands and types of pressure gauges were different. Personal recommendation if there is a problem of replacement or return to the supplier, procurement of new products, and send check calibration analysis as follows:A pressure gauge without indication. Reason: 1, pressure pipe on the cut off valve does not open; 2, pipe plug; 3, spring tube joint too much dirt siltation and plug; 4, spring tube cracking; 5, the center gear and fan tooth wear too much, and is not engaged.Two, pointer shaking large. Reasons: 1, the pressure of the medium to be tested; 2, pressure gauge installation position of vibration
- Q: Do pressure gauges need to be used in atmospheric hot water boilers?
- There is no need to install pressure gauges in the atmospheric hot water boiler, but the piping system is best installed, because the system circulation should be monitored. Also, the furnace body and the system line shall be equipped with thermometer.
- Q: What are the differences between axial pressure gauges and radial pressure gauges?
- Difference：The radial pressure gauge, the axial pressure gauge difference mainly looks at the pressure gauge thread joint position, the thread joint under the dial plate is radial, with the dial plate vertical is the axial.Brief introduction:The pressure gauge is axial, that is, the pressure gauge, the threaded joint and the dial are vertical. In the control and measurement process, due to the mechanical axial pressure gauge elastic sensitive element has the characteristics of high mechanical strength and convenient production, which has been more and more widely used mechanical axial pressure gauge.The radial pressure gauge is very easy to install, particularly suitable for installation in the valve, widely used in all kinds of water system, chemical industry, petroleum industry, shell: stainless steel, surface: glass, pressure gauge: tube spring element.
- 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.
