- Q:How does the fire pump pressure meter work?
- Imagine a floor of 3 meters, the 27 floor is 81 meters, so at least 81 meters to provide water pump pressure + atmospheric pressure, converted to 9.8*81*1000pa+1.01*100000pa=0.8938Mpa
- Q:What does "Y" mean? What does "Z" mean?
- In the instrument type representation: Y said Z said pressure, vacuum or damping, J precision or rectangular, A ammonia table, X signal or electric contact, XC said magnet electric point, said P E said the diaphragm membrane box, F corrosion, N said seismic, T said the spring tube, B said stainless steel and so on.
- Q:How to check the fire valve pressure gauge as normal?
- The pointer is normal in the green area!
- Q:How do remote pressure gauges receive frequency conversion?
- Frequency converter 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.
- Q:What does the pressure gauge 1% mean?
- Pressure gauge accuracy of 1%, that is, the standard accuracy level of 1 pressure gauges.A pressure gauge with a rating of 1, indicating that the measuring range of the pressure meter is 1% of the full range.That is, 1MPa pressure gauge, the accuracy level is 1, that is to say, this value error is + 0.01MPa.5MPa pressure gauge, accuracy class is 1, that is to say, this value error is + 0.05MPa.If the accuracy level is 1.6, the measurement error is + 1.6%.1MPa pressure gauge, the accuracy level is 1.6, the value of this error is + 0.016MPa.
- Q:The water remote pressure gauge hands swing frequently do?
- 1) without instructionReason: 1 the dirt in the pipe is blocked up and the dirt in the reed pipe is removed2, the sector gear and pinion resistance is too large, adjust the clearance to moderate3, two gear wear too much, unable to mesh, replace the two gear(2) the pointer is turning slow or beatingReason: 1, the transmission parts of the clearance is too small, the transmission is not flexible, increase the gap, or add a little Watch Oil2, moving parts between the active parts of fouling, transmission is not working, cleaning, rust removal, in addition to dirt or replacement transmission3, free end and connecting rod connection is not flexible, adjust the connection mode until flexible4, the pointer and dial, table cover friction correction pointer, thicken the glass lining below(3) the rotation of the pointer is not smoothReason: 1 fan gear tilt, correct or replace gear2 needle shaft bending alignment pin shaft3 plates, bending, correcting, flatness of plywoodThe 4 pillar tilts and causes the upper and lower clamping plates to be not parallel to correct the pillar, and the gasket is added and added so that the splint is parallel(4) the pointer jitter is largeReason: 1 medium pressure fluctuation, close the valve opening2, the gear is not fit well to adjust the gear matching condition3, the needle sleeve and the shaft do not match well, adjust the matching gap between the pointer sleeve and the shaft(5) the pointer deviates from the zero position and the error exceeds the allowable valueReason: 1.

- Q:How many degrees above is the high temperature pressure gauge?
- The use of environmental conditions: -40~200 degrees (YTH), relative humidity is not greater than 85%Effect of temperature: when the temperature deviates from 20 + 5 DEG C, the additional error of temperature is not more than 0.4%/10 degrees centigrade
- Q:The working principle of the Bourdon tube pressure gauge
- Bourdon tube pressure gauge is spring tube pressure gauge.Its working principle is that:The working principle of the spring tube type pressure gauge is spring tube; under the action of pressure, the free end displacement, the displacement of the rod drives the transmission amplification mechanism, the pointer deflection, and indicate the pressure value on the scale.Bourdon tube pressure gauge is mainly composed of a threaded joint holder, spring tube, rod, screw, gear sector, small gear, hairspring, pointer, upper and lower clamping plate, dial, case, shell etc..The function of each component in the drive amplifier mechanism:(L) pull rod - transfer the displacement of the free end of the spring tube to the sector gear;(2) the sector gear converts the line displacement to angular displacement and then passes it to the pinion and has an amplification effect;(3) the pinion drives the coaxial pointer to rotate, indicating the measured pressure on the dial;(4) - the gossamer fan gear and small gear tooth profile keep one-way contact clearance contact two gear, in order to reduce the return difference;(5) adjusting the screw - changing the position of the adjusting screw can change the length of the short arm of the sector gear, so as to change the drive ratio;(6) the upper and lower clamping plates fix the components together to form a set of transmission mechanisms.The drive mechanism, also known as the movement, is the heart of the pressure gauge. Its function is to enlarge the displacement of the free end of the spring tube so as to achieve the purpose of easy reading.
- Q:The structure and working principle of the membrane box of the membrane pressure gauge?
- The free end of the film box is divided into two parts, and the lower end is an air inlet. Then the upper end of the film box is used for driving the connecting rod to work
- Q:The difference and relation between the electric contact pressure gauge and the remote pressure gauge
- The use of the two is different. One is used to control the other, and the other is to send the signal to the farther end of the monitor.The electric contact pressure gauge consists of measuring system, indicating system, magnetic auxiliary contact device, shell, adjusting device and junction box (plug seat), etc.. The working principle of electric contact pressure gauge is spring pipe in the measuring system under the action of the pressure of the measured medium based on the force generated by the end of spring pipe corresponding elastic deformation displacement transmission rod through a gear transmission mechanism with the help and amplification by the fixed gear instructions (along with contact) by the measured value indicated in the table. At the same time, when the contact and set on the pointer (upper or lower) contact (break or close) instantaneous, resulting in the circuit control system can be switched on or off in order to achieve the purpose of automatic control and alarm.The remote pressure gauge is suitable for measuring the pressure of liquid, steam and gas which can not corrode the steel and copper alloy. Because the resistance transmission pressure gauge is arranged inside the sliding line resistance transmitter, so the measured values of two meters on electricity to far away from the measurement, in order to realize centralized monitoring and remote control. In addition, the pressure gauge is capable of indicating pressure in place so as to facilitate on-site inspection.
