- Q: The electric contacts pressure gauge, electric contact is often the first contact is damaged, burned, the general use of the electrical contacts to control AC contactor, there is no way to prolong the service life, add a damping absorption of the original electric contacts at both ends can be? What should I do?
- Although the contact points of an electric contact meter can be directly used for AC 380 V voltage, it is easy to burn out. In daily design, the 24 volt DC power supply is used to switch the DC relay, so that the contact life can be prolonged. 24 V DC power is also a contactor price.
- Q: Cutting acetylene bottles on how there are 2 pressure gauges, the general number of suitable adjustment
- Two pressure gauges of an acetylene bottle, one is the pressure in the bottle, one is the working pressure, and the pressure in the bottle is the magnitude of the pressure of the remaining acetylene in the acetylene bottle, and is not adjustable. The work pressure is the pressure that is adjusted by the pressure reducing valve. Usually work pressure is low, adjust to 2 or 3 atmospheric pressure can be
- Q: Function of electric contact pressure gauge
- Function of electric contact pressure gauge:The utility model is used for measuring the positive and negative pressure of the gas and liquid medium which does not corrode copper and copper alloy, and sends out signals when the pressure reaches a predetermined value, and the control circuit is switched on to achieve the purpose of automatic control of the alarm.Electrical contact signal pin in electric contact pressure gauge device, a permanent magnet can be adjusted, can increase the contact force, speed up the contact action, so that the contact reliability, eliminating the arc, can effectively avoid the instrument working environment due to frequent vibration or medium pressure pulsation caused by contact off. Therefore, the electric contact pressure gauge has the advantages of reliable operation, long service life and large power of the contact switch.
- Q: What are the types of pressure gauges? What is the principle of each? Who has other information about industrial hardware? Give it to me -- thank you
- The oil pressure gauge is the vibration proof pressure gauge (the main role is to earthquake, the pointer swing damping effect)The pressure gauge is divided into four kinds according to the sensor: Bourdon tube pressure gauge, diaphragm pressure gauge, diaphragm pressure gauge and diaphragm pressure gauge.Basically, the spring element is different. The spring tube is used to indicate the pressure through the deformation of the 270 degree C tube;The diaphragm drives the pointer through a single diaphragm;The film box is equivalent to the two diaphragm welded together, just like a box, only for measuring gas.The diaphragm is a combination of diaphragm and spring tube.
- Q: Our unit has a 2.2kW water supply motor, running with EV1000. How to control according to the remote pressure gauge? Is to control the pressure within a certain range. Read the instructions, there is a process closed loop control parameters, but not quite understand.. please expert advice. It's best to say what parameters you need to change.Added 15 points to answer satisfaction.
- A specification is very simple, I do I happen to water without Emerson, you can set the PID terminal operation, process control, pressure of fifteen percent to twenty-five, remote pressure gauge 1.6MPa, GND, red, green ten 10V yellow VI, if I can help you find the manual selected parameter settings, welcomed the exchange of my QQ907187542 if you have an electronic version of the instructions can also send me a
- Q: How about the model of seismic pressure gauge?
- There is a general proof letter "N"
- Q: 410 how about the pressure of the pressure gauge?
- Is your 410 refrigerant? In general, the pressure is about 2.8MPa, and the pressure is completely related to the temperature. Therefore, it is more appropriate to select a pressure gauge with a maximum value of about 5.0MPa. The reading of the pressure meter is the same as that of the ordinary pressure gauge. There is no special place, unless your pressure gauge is foreign, you can convert according to the relevant units.
- Q: 250MPa calendar force, 150MPa verification point when the step-up is 148MPa, when the buck is 149MPa, please tell me how to calculate the value of error, return error is how to count? Thank you
- Pressure meter return error: under the same conditions, the measured value is constant, the measuring instrument travel direction is different, the absolute value of the difference of its indication value. Note: return error is also called lag error."The return error" and "dead zone": JJF1001 "general terms and definitions for measurement", the term "no return error", but in 7.13 another definition of the term "dead zone" to describe "causing maximum variable interval dynamic measuring instrument in response to changing incentives". Therefore, return error is an index to measure the response characteristics of equipment".Does the return error accumulate? Take the positive and negative rotation of the motor as an example, the return error of the transmission mechanism should not be accumulated once and for all. In other words, back and forth movement many times, return error or fixed interval, does not increase.Application in the motor: the motor itself is no return error, how much encoder reads, how many pulses the stepper motor turns, and the servo system is usually higher than the stepper motor accuracy. The return error is generated by the drive mechanism, such as the screw rod connected on the output shaft of the motor. Therefore, the servo system can accurately control the motor, can't handle the return error. Therefore, the zero bit switch can eliminate zero return error in the course of motion, in addition to the zero power seeking of the incremental encoder. Even if the absolute encoder does not require power on and zero, the photoelectric switch can also be used to eliminate the return error. When there is no return error in the direction of return, it is necessary to set a zero position switch at both ends, so that the motor is backward to zero in this direction, and then the zero is used to measure the movement displacement.
- Q: What is the PSJ of the pressure gauge?
- PSI full name in English is Pounds per square inch.P is pound pound, S is square square, and I is inches inch.All the units in metric units can be calculated: 1bar = 14.5psi1psi=6.895kPa=0.06895barEurope and the United States and other countries are accustomed to using psi as a unitIn China, we usually use the "kilogram" to describe the pressure of the gas (not the "Jin"). The unit is "kg/cm2", and a kilogram of pressure is one kilogram of force acting on one square meter.While in a foreign country commonly used unit is "Psi", the unit is "lb/in2", is "psi", this unit like Fahrenheit (F).In addition, there are pressure units such as Pa (Pascal, Newton, one square meter), KPa, MPa, Bar, millimeter water column, millimeter mercury column, etc..1 bar (bar) =0.1 MPa (MPa) =100 kPa (KPa) =1.0197 kg / cm21 standard atmospheric pressure (ATM) =0.101325 MPa (MPa) =1.0333 bar (bar)Because the unit is very small difference, if it is not to be accurate calculation, you can remember:1 bar (bar) =1 standard atmospheric pressure (ATM) =1 kg / cm2 =100 kPa (KPa) =0.1 MPa (MPa)
- Q: What is the function of the pressure gauge bend?
- The formal name of the table bend is called the buffer tube, which mainly has the function of reducing shock and shock. It can also play a certain role in heat dissipation of the medium with higher temperature, and protect the pressure gauge and reduce the temperature of the pressure gauge to affect the error. The damping screw at the orifice of the part of the pressure gauge has a throttling effect by reducing the flow area. Mainly useful for medium pressure pulses.
