FAQ

Please show the hydraulic gauge is what pressure? Know the hydraulic piston area with hydraulic products area, how to calculate the pressure?

Hydraulic gauge display is connected with the hydraulic oil pressure oil chamberKnow the piston area of hydraulic machine, but also have to know exactly the external load, also have to consider the mechanical seal resistance, resistance and other factors, to get an ideal external value divided by the piston area can get relatively accurate pressure value.

Can you use the precision pressure gauge of level 0.25, measuring range (0~10) and MPa to verify the general pressure gauge of level 1, measuring range (0~6) MPa? Why?

There is no problem with the standard meter. The measuring instrument should use a 0.05 stage piston pressure gauge

What is the actual size of the pressure gauge nozzle G1/2?

G stands for non threaded cylindrical pipe threadsTooth angle: 55 degrees: G1/2-LH (left, right, wrong)Size code, number of teeth per inch, diameter, middle diameter, path1/8 289.728, 9.147, 8.5661/4 1913.157, 12.301, 11.4453/8 1916.662, 15.806, 14.951/2 1420.955, 19.793, 18.6313/4 1426.441, 25.279, 24.11711133.249, 31.77, 30.29111/4 1141.91, 40.431, 38.95211/2 1147.803, 46.324, 44.845

Fire hydrant pump, spray pump, starting pump, pressure gauge and spray pump, pressure switch is how to wiring?

A total of 4 lines of pressure: a pair of lines directly to the alarm module feedback, a pair of lines directly to the pump control cabinet pump startThe electric contact pressure meter has 3 terminals: one upper limit, one lower limit, one public and three wires directly to the corresponding terminals of the voltage regulator box.Spray pump: spray pump (English Sparypump) is mainly used in mud pump matching oil drilling equipment, spray pump is in the process of the operation of the pump in the cylinder liner and piston for washing and cooling, and used it to transport mud.

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.

What's the function of the oil pressure gauge? Where does it fit?

Oil filled pressure gauge can reduce the swing range of hands, generally used in the equipment of large vibration on.

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.

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

It shows two pressures, 1 side pressure and 2 side pressure, or the pressure before the valve and the working pressure after the valve.
