Q:Do pressure gauges need to be installed for pressure drainage?
Unwanted! Plainly, there is no need to install
Q:What will happen to the calibration process if the calibrator of the pressure gauge is not clean?
The pressure caused by the numerical instability, recommend the use of multi row several times before the air, after use will be a lot easier, modaobuwukanchaigong.
Q:What is the quality of the common electric contact pressure gauge?
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.
Q:What is oil immersion pressure gauge?
An oil pressure gauge is a pressure gauge that is filled with a damping fluid (usually silicone or glycerin) in the case. Also called proof pressure gauge is suitable for environmental vibration places and medium pressure pulsation larger occasions.
Q:How is the pressure gauge ABC divided?
Instrument certification according to the location of the importance of varying degrees, generally divided into a, B, C three grades.A class is generally used in pressure control strict locations, requiring accurate instructions, is the focus of monitoring instruments, usually for an annual or semiannual inspection;Class B is generally used at locations where pressure control is more stringent and requires more accurate instructions. It is a general monitoring instrument, usually tested annually or two years;Class C is generally used in places where the pressure control is not strict and can be used as a reference value. It is a non monitoring instrument, usually tested for many years or replaced after failure;
Q:What is the pressure gauge cock
The pressure gauge is a pressure gauge cock, special three way cock. The characteristic is that when the pressure gauge pipe is flushed, the medium is not allowed to enter the pressure gauge, and the medium can be discharged directly. This is to protect the form of pressure gauge design.
Q:Why can't ordinary pressure gauge be resistant to high temperature?
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 does "Y" mean? What does "Z" mean?
Y- stands for the pressure gauge, and Z- stands for the vacuum meter.
Q:What kind of pressure gauges do you need for repairing refrigerators?
Maintenance of refrigerators requires at least 3 pieces of pressure gauge, 2 pieces, 2.4 kilograms, a piece of 1.5. The refrigerator low pressure gauge can not measure high pressure.1. Maintenance of pressure gauges for refrigerators is a necessary tool for maintenance.2, through the high-low pressure to determine the operation of air conditioning.3. Vacuum system and evaporation pressure are determined by observing low pressure meter when pumping vacuum and charging refrigerant.4. Watch the high and low pressure meter at the same time when the refrigerator is running, and pass the evaporation pressure of the low pressure meter.
Q:Ytn10 and yn10 have these two types of pressure gauges? What do these two models stand for?
YN and YTN represent proof pressure gauge is just not the same manufacturer mark.Y stands for pressure gaugesT stands for spring tube structureN shockAlso, there is no YN10 and YTN10, only YN100 and YTN100
