Ⅰ、Main functions:

The machine can be used for the determination of anti-impact performance of metal materials when it is under dynamic loading, thus judged the quality of materials under dynamic loading. It is applicable for the laboratory, which does continuous compact tests, metallurgy, machinery manufacturing, and other industries.

Ⅱ、Product features:

The machine with the semi-automatic control, operates easily and efficiently. It uses the electric control the knife of impact to raise, impact and fall. Moreover, the machine can use the remaining energy to raise and fall to prepare the next test automatically after thrusting specimens.

Q:What will happen to the calibration process if the calibrator of the pressure gauge is not clean?: Because the air is compressible, the hydraulic device check if there are a lot of air, the number of hydraulic oil every pressure signal needs to inject the high pressure chamber is bigger, the exhaust is actually check as far as possible before the hydraulic oil filled pressure chamber, to reduce the need to check the injection quantity. In the case of more air, the screw type pressure generating device may not travel enough, need to play more than a few times, other pressure generating devices also need to operate more than a few times.If there is a small amount of air in the hydraulic device, the pressure of the air will be more stable because of the cushion of the air.

Q:The composition of the pressure gauge?: The pressure gauge mainly has following parts and components: joint, spring tube, seal piece, movement, connecting rod, dial, pointer, lining ring, watchcase, watch glass, cover ring. The key components are joint, spring tube and core.

Q:Why isn't the pressure meter back to zero?: When the pressure gauge is removed and the readings are still not zero, the pressure gauge needs to be maintained or repaired.Please find someone to open the examination for specific reasons.

Q:What is the maximum working pressure 6Mpa? How much do you want to fit the pressure gauge?: ~15mpa, according to the use of pressure 2~3 times the range, the use of reliable.

Q:Ytn10 and yn10 have these two types of pressure gauges? What do these two models stand for?: Yes, YTN10 said that YN10 stainless steel vibration proof pressure gauge, ordinary proof pressure gauge but you give these or not complete.

Q:Can the pressure meter read on the computer?: This one is ok. With a CWY series of digital watches, in a pressure source, coupled with the computer on it. Provide pressure with a pressure source, connect a digital meter to 485, and then connect to the computer. On the computer, you can read directly the pressure values for each point of the pressure. On the computer will directly generate reports, and finally print out the data directly with the computer just fine. Our shipyard is used Shaanxi Chuangwei this equipment. Very convenient！ Increase of efficiency！

Q:What's the difference between radial pressure gauges and axial pressure gauges? Which one has the best edges?: With no edge, with the edge of the panel is installed, the panel installed with installation table Meng, two, this difference is in the bottom, one is in the back, the general panel mounted in the axial installation

Q:Is the boiler pressure gauge mandatory?: The use of pressure meter of boiler has its special requirements, because the security level of the boiler is high, prone to burst pipes, excessive temperature and pressure, the drum is the key equipment, so the more stringent requirements than the general pressure gauge. Considering the safety of the boiler, steam boiler and national mandatory requirements, the pressure gauge must be per package the first half of the test once, also must have the qualification of certification institutions. At the same time, the pressure gauge requires a large dial of 250. In fact, not just the boiler requirements, other types of pressure vessels have such requirements.

Q:What is the pressure gauge called?: Pressure level transmitter, common flavor flange type pressure level transmitter and static pressure level gauge

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.
