- Q: The 3 lines of the remote pressure gauge are connected to an external potentiometer of the frequency converter. What parameters can be adopted to adjust the pressure? Thank you
- Constant pressure water supply principle of remote pressure gauge:1. use frequency conversion motor to realize constant pressure water supply. Constant pressure water supply system based on pipeline pressure (i.e. remote pressure gauge readings) to set parameters, through computer-controlled inverter output frequency to adjust the rotational speed of water pump, to achieve closed-loop pipeline pressure regulation (PID), the automatic water supply system of constant to the set pressure value: the water consumption increases, the frequency increases, the pump speed is accelerated, water supply increases; reduce water consumption, reduce the frequency of pump speed slow down, water supply is reduced, so as to ensure the water supply efficiency requirements of water pressure and water at the same time, to improve the water quality and water supply efficiency, "how much water, how much water supply"; the device does not need to build the high water tank, water tower, no two pollution, is a modern building water supply equipment ideal.2. use the regulating valve to realize constant pressure water supply. The constant pressure water supply system based on pipeline pressure (i.e. remote pressure gauge readings) to set parameters, the computer controls the pump outlet valve open, closed loop water pressure regulation (PID), the automatic water supply system of constant to the set pressure value: the water consumption increases, the valve opening increases, water supply increases; reduce water consumption, reduces the valve opening, water supply is reduced, so as to ensure the water supply efficiency requirements of water pressure and water at the same time, in order to improve the water quality and water supply efficiency, "how much water, how much water supply".
- 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: Pointer form of pressure gauge, with digital pressure meter, advantages and disadvantages?
- 1 pointers are generally cheap, digital display is generally expensive.2 pointer is simple, more convenient operation, digital display is a little troublesome.3 pointer is not accurate digital display, sensitivity will certainly be different.4 pointer, I do not know whether you can bring DC4-20MA or RS485, it should be no, digital display can bring these functions, networking.
- Q: How to determine the accuracy level of a pressure gauge?
- The accuracy levels of the precision pressure gauges are 0.1, 0.16, 0.25 and 0.4 respectively. The accuracy levels of the general pressure gauges are 1, 1.6, 2.5 and 4 respectively. The method of selecting the accuracy level of the pressure gauge shall be based on the requirements of the production process, economic, practical and testing methods, and the accuracy grade shall be determined according to the allowable error of the minimum pressure measured. Precision class calculation method: the actual error value / actual range * 100% out of the figures, remove the number, get the number close to the above numerical value, the accuracy level is how much
- Q: What pressure gauges are used in a pressure vessel?
- Under normal circumstances, the use of 0-0.1Mpa range of pressure gauges. If the pressure is small, you can use the Kpa table
- Q: Vacuum table refers to the vacuum or pressure gauge?
- Vacuum negative pressure.
- Q: What is the range of use of a pressure gauge? Why is it at its measuring range of 1/3-2/3?
- Pressure gauges are common range instruments, the statutory use of membrane pressure gauges should be used. (2) when the pressure of the pressure is stable, the normal operating pressure shall be at 1/3 2/3, 2 of the upper limit of the measuring range of the instrument
- Q: How do you read the dial diameter of the pressure gauge?
- Generally speaking, how many round, or diameter XXmm, common 40mm, 60mm, 100mm, 150mm, 160mm dial, etc., so nominal
- Q: Are you talking about using a gold contact? I'm a small relay for 24V. Do you need a gold contact?Let's talk about it.
- Yes, the watch itself has a contact point. Don't you mean the table?
- Q: Do pressure gauges need to be installed for pressure drainage?
- Unwanted！ Plainly, there is no need to install
