Product Description:

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.

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:Will the pressure gauge of the fire extinguisher leak?
The bottle body collision, deformation and cracking damage of nozzle nozzle is not to use the fire extinguisher pressure gauge in the red zone under voltage, need maintenance, seal damaged also need maintenance, depression
Q:Y-100 what is the thread of the pressure gauge?
Y-100 is the ordinary 100 meter diameter of the pressure gauge, 100 table diameter thread interface, standard is M20*1.5.
Q:The gas pressure reducer has two measuring ranges, one big and one small pressure gauges. What's the function of each? What's the meaning of a red line on some pressure gauges?
Large display inlet pressure, small display outlet pressureThe red line is generally two or a thick, this is the user's own painting, said the pointer is the normal status in this area, especially for the frequent adjustment of the place, as long as the watch will know to what extent the regulation
Q:Excuse me, where can I check the pressure gauge in Chongqing?
The local quality and Technical Supervision Bureau will be fine. You can also go to your district level Technical Supervision Bureau to do the verification, they are all legal measurement accreditation institutions.The price depends on what kind of pressure gauge you have, the vacuum meter or not, the range, the accuracy level, the medium, and so onIn fact, the test is more expensive than buying a new watch, but there is no way that the state has to check the mandatory measuring instruments, the new table should also be checked again, half a year.
Q:What is the working principle of the pressure gauge?
The models are different and the working principle is different1.WTY-1 - racy liquid pressure type thermometerThe model WTY liquid pressure thermometer utilizes the thermal expansion of a liquidA temperature, capillary, and Bourdon tube for measuring temperatureThe enclosed system is filled with a temperature measuring medium - liquid, when heatedWhen the temperature changes, the pressure in the closed system is due to the liquid bodyThe product changes as a result of a change in the curvature of the spring tubeThe displacement is generated by the end, and the pointer is driven through the connecting rod and the transmission mechanismTurn on the dial and indicate the temperature to be measured. This instrumentThe utility model has linear scale, small temperature package, fast reaction speed and sensitivityHigh, direct reading and other features, almost a collection of glass rod thermometer,Bimetallic thermometers, steam and gas pressure thermometersAdvantage, when the current application of the widest range of performance of the most comprehensive kindMechanical temperature measuring instrument.
Q:What pressure gauges are used in a pressure vessel?
Pressure gauges for 0-0.1Mpa range for normal pressure vessels. If the pressure is small, you can use the Kpa table.The selection of pressure gauges has the following requirements:(1) the pressure gauge selected must be adapted to the medium in the pressure vessel. Because some mediums are corrosive to the material used in the pressure gauge, it should be noted that the material used in the pressure gauge cannot be physically and chemically reacted with the medium in the pressure vessel installed.(2) the accuracy of pressure gauges used in low pressure vessels shall not be lower than 2.5; the accuracy of pressure gauges used in medium and high pressure vessels shall not be lower than 1.5.(3) the limit value of the pressure dial scale should be 1.5-3.0 times of the highest working pressure, and the best choice is 2 times. Dial diameter should not be small, dry 100 mm.
Q:How to connect the household air conditioner pressure gauge?
Before adding snow to open air conditioning, after the external machine started, the table connected to air conditioning gas nozzle (to receive a relatively thick that housekeeper, air-conditioning pressure in general 2.8MPA
Q:How about the model of seismic pressure gauge?
There is a general proof letter "N"
Q:What is the pressure gauge cock
Connecting device for pressure gauge and measuring body
Q:How do you contact the pressure meter to the pump control box?
The electric contact pressure gauge has upper limit and lower limit contact (common midpoint). The lower contact (less water start, parallel contactor normally open contact retention) connected to the pump contactor coil; the upper contact (water full stop) connected to intermediate relay coil, the normally closed contact string into the pump contactor coil circuit of the intermediate relay action, disconnect contactor coil power source. If the contactor is large, then the lower limit contact will be amplified by another relay.
