- Q:The difference and relation between the electric contact pressure gauge and the remote pressure gauge
- The use of the two is different. One is used to control the other, and the other is to send the signal to the farther end of the monitor.The electric contact pressure gauge consists of measuring system, indicating system, magnetic auxiliary contact device, shell, adjusting device and junction box (plug seat), etc.. The working principle of electric contact pressure gauge is spring pipe in the measuring system under the action of the pressure of the measured medium based on the force generated by the end of spring pipe corresponding elastic deformation displacement transmission rod through a gear transmission mechanism with the help and amplification by the fixed gear instructions (along with contact) by the measured value indicated in the table. At the same time, when the contact and set on the pointer (upper or lower) contact (break or close) instantaneous, resulting in the circuit control system can be switched on or off in order to achieve the purpose of automatic control and alarm.The remote pressure gauge is suitable for measuring the pressure of liquid, steam and gas which can not corrode the steel and copper alloy. Because the resistance transmission pressure gauge is arranged inside the sliding line resistance transmitter, so the measured values of two meters on electricity to far away from the measurement, in order to realize centralized monitoring and remote control. In addition, the pressure gauge is capable of indicating pressure in place so as to facilitate on-site inspection.
- Q:How do you see a vacuum gauge?
- The vacuum pressure gauge on any device has its working pressure and can be read correctly! Only it can see the negative pressure!
- Q:The role of a pressure gauge
- As the name suggests, it is to measure the pressure, welding need to ensure adequate flow of gas protection, sufficient flow is the premise of sufficient pressure in the tank, pressure gauge is to show the pressure inside the tank is enough
- Q:Want to buy a pressure gauge, but do not know how to determine the pressure gauge model, you can only measure the size of the dial and then the size of the thread, there is no master pointing out the pressure gauge model specifications?
- The best consultation with manufacturers of pressure gauges, they will give you a professional answer, my home pressure gauge is Nanjing Wanda instrument factory, the use of sleep can also be, the price is not expensive
- Q:We use seismic pressure gauge oil, do not know how to come back. Trouble master solution
- Generally do not recommend their refueling. First of all, to check that the oil leak there, only the oil spill point can be solved again, do not solve, plus the leak. Say you add what kind of oil, general manufacturers have silicone oil (silicone oil has a variety of specifications), some glycerin, if two kinds of oil mix is more trouble, affect observation pressure. It is recommended to be returned to the manufacturer for repair.
- Q:What is the calibration cycle for the pressure gauge / thermometer / flowmeter? Is there a standard to check?
- Provisions concerning the period of verification:1 national inspection category (a total of 4 categories: trade settlement related instruments, security related instruments, medical, health related, environmental related) measuring instruments in accordance with national regulations, and strictly enforced. For 1 years, but also for half a year.2 non - strong measuring instruments, the use of units generally can determine its own calibration cycle. Can also be regularly checked, or one-time verification. Generally ranging from 1 to 3 years. Just do it yourself. If it is enterprise, it is better to use document to stipulate.
- Q:Why should I add a plug valve before the pressure gauge?
- The installation of plug valves in front of the pressure gauges is mainly for the convenience of disassembly and installation of pressure gauges.
- 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 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:There is no pressure gauge in the process of adding fluorine to the air conditioner
- Methods: fluoride 1. will be the first operation of air conditioning in the cooling mode, the fluoride mouth with Freon tank on one end of the tube with fluorine and fluoride, the other end tube (with fluoride thimble tube), installed in the low-voltage end of outdoor unit of air conditioner (suction tube) fluoride mouth. 2., open Freon tank plus fluorine valve on the mouth, can directly add fluorine to the air conditioning, fluorine amount of how much, should refer to the air conditioning nameplate marked "fluoride charge" for fluorine. Quantitative filling with scale. After the fluorine is finished, turn off the valve on the Freon tank and the fluorine nozzle, and let the air conditioner continue to operate. To observe the effect of air conditioning refrigeration, such as air conditioning to achieve normal cooling effect, low end remove outdoor machine (suction) plus fluoride mouth of fluoridation pipe, tighten the cap, and the mouth of the air conditioning fluoride can be used normally
