- Q:Band sawing machines sometimes fail to rise, sometimes very slowly, and sometimes pressure gauges have no pressure
- Remove the solenoid valve that lights up and wash it
- Q:I want to use a frequency converter and a remote pressure gauge to control a submersible pump, using the on-off control, constant pressure water supply, how to connect and set up
- With PID function, detailed look at the inverter PID description will understand
- Q:How do remote pressure gauges receive frequency conversion?
- [1] inverter 10V, VF, GND point is the voltage control frequency of external contacts, is not directly connected to other signals, and can not be defined as other functions, in addition to voltage signals. As for the remote pressure gauge, one is divided into upper and lower limit, switch signal output, (also an instant signal, leaving the lower limit pointer is disconnected, cannot keep) called electric contact pressure gauge; there is no so-called resistance output, the upper and lower limit, through the pressure controller or by the PG board needs to transform into a voltage or current signal to control the frequency converter. Therefore, the remote pressure gauge can not be directly in the inverter 10V, VF, GND points, you need to control the inverter through some means.[2]: pressure gauge pressure gauge (English Name: pressure gauge) refers to the elastic element as the sensitive element, measuring and indicating higher than ambient pressure meter pressure gauge installation of Shanghai Wang ring is widely used, it almost all the industrial processes and scientific research. In the heat pipe network, oil and gas transmission, water supply system, vehicle repair and maintenance shop, and other fields can be seen everywhere. Especially in the control and measurement process, because the elastic sensitive element of mechanical pressure gauge has the characteristics of high mechanical strength and convenient production, the mechanical pressure gauge is widely used.
- Q:How do you recognize the pressure gauge?
- To recognize the pressure gauge units, the general units are Mpa, mbar, bar, PA, and so on. Then see where the pointer points.
- Q:410 how about the pressure of the pressure gauge?
- R-410A temperature see the red mark of the inner ring, the corresponding pressure is the two value of the outer ring, the outer ring is psi pounds, and the second circle is bar.- 1bar=1kgf/cm1psi=6.9kPa (1MPa=145psi)- 1MPa=10kgf/cm1MPa=1000kPaThe pressure corresponds to the temperature chamber. The temperature is known when the pressure is known and can be checked.
- Q:If the plot pressure gauge 2.5MPA and the daily work range 1.23MPA-2.12MPA, what sort of pressure gauges should we choose?What are the methods of calculation?
- China's general industrial pressure meter is divided into 4 accuracy levels, in line with the JJG52-1999 "Bourdon tube general pressure gauge, pressure vacuum table and vacuum meter" verification regulations, the pressure table prepared by the allowable error. These 4 levels of accuracy are: 1, 1.6, 2.5, and 4. Allowable error (calculated according to the percentage of the upper limit of measurement) is 1%, 1.6%, 2.5%, 4%, respectively.China 2005 new digital pressure meter verification regulations promulgated and implemented, in line with JJG875-2005 "digital pressure gauge verification regulations.". The accuracy of the pressure is respectively 0.01%, 1.6%, 0.02%, 0.05%, 0.1%, 0.2%, 0.5%, 1%, and so on.
- 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:How to adjust the upper and lower limits of the upper and lower limit of the electric contact pressure gauge?
- The electric contact pressure gauge is directly at the center of the table to the point where you need it. Contact red green is to stop the equipment start equipment you need to adjust according to the pressure, if we can use the special seismic AC electric contact pressure gauge, can only provide AC voltage, if you don't know is AC or DC on the choice of photo electric contact
- Q:For example, I want to stop the pump before the pump pressure signal and now, through the pump pressure signal, adjusting the frequency of the pump, to ensure the pump pressure at a fixed value, it will the pressure signal through the pressure transmitter is good or remote pressure gauge? Shall I use the remote pressure gauge before pumping and use the pressure transmitter after the pump? Is the electric contact pressure meter reliable?
- The remote pressure gauge is suitable for measuring the pressure of liquid, steam and gas which can not corrode the steel and copper alloy.The instrument is provided with a slide line resistance transmitter, the measured value to the value of electricity to two meters away from the measuring point, to realize centralized monitoring and remote control, the instrument can also indicate the pressure, in order to facilitate the on-site process inspection.The meter consists of a spring tube, a pressure gauge, a slide wire, a resistance transmitter, etc..The function principle of the mechanical part of the remote pressure gauge is the same as that of the common spring tube pressure gauge.Because the resistance transmitter is arranged on the gear drive, so when the fan gear shaft gear transmission mechanism of deflection, rotating arm resistance transmitter (brush) corresponding to the deflection due to sliding on the resistor, brush, change make the changes in the measured value of pressure change as the resistance value, and to the two instrument, indicating a corresponding reading value. At the same time, the primary instrument also indicates the corresponding pressure value.Two kinds of pressure transmitter pressure of the measured medium into high and low pressure chamber two, role in the delta element (i.e. sensitive element) on both sides of the diaphragm, by filling liquid on both sides is transmitted to the measuring diaphragm and the element in isolation. Measure the electrodes on the diaphragm and the insulation plate on both sides to form a 4-20mA standard signal output by the capacitor and send it to the program control system.
- Q:What's the difference between a pressure gauge and a negative pressure meter?
- A negative pressure meter is also a pressure gauge. It is only used to measure negative pressure. Negative pressure is relative to standard atmospheric pressure.
