- Q: Is the gasket sealed at the pressure gauge connection?
- Encryption pads are required, as well as encrypted sealing rings or raw tape.The rubber gasket is a self expanding sealing gasket, belonging to the sealing component of the pipeline. The gasket is composed of an outer ring, the middle ring and the inner ring expansion of three parts; the outer ring and the inner ring is generally elastic sealing ring, the middle ring at the center of a ring on both sides of the bubble structure, hollow ring, outer ring seal ring outer ring and the inner side of the opening; the inner ring is divided into two parts installed in the middle, inside and outside the ring structure of the global expansion.Rubber gasket is also very extensive use, we usually drink drink cover, there are a layer of rubber pad, that is used to seal the use of this to isolate the flow of air from the outside. The working principle of the machine is static and dynamic. In short, are used to carry out isolation from the outside world or a place, the work principle of the gasket is also very simple, it can be said that there is no too many principles, that is, isolation.
- Q: Is the absolute pressure or relative pressure measured by an oil pressure meter or a barometer?
- The relative pressure is also called table pressure. The pressure shown by the pressure meter is the gauge pressure (relative pressure), which is the difference between the real pressure and the atmospheric pressure somewhere in the equipment.
- Q: 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, and the corresponding wiring diagram is on the box door
- Q: Drese D800 inverter and a remote pressure gauge how how to set the constant pressure connection
- To see the resistance type or current type if the resistance type the three wire tap is connected with the analog input quantity in the inverter voltage, is connected to the rest of the 10V, a ground Analog ground. If the constant pressure water supply (gas), the frequency of a given set of PID given to in the PID control parameters which will change into analog voltage control parameters. If it is a total of two line current, a grounding current in the analog input, the other end is connected to simulation, then short circuit analog and digital, parameters are set to PID control, but also in the PID control parameters which will the parameters changed into current analog control.
- Q: What are the procedures for checking the pressure gauge in that department?.
- The Bureau under the quality supervision bureau is a pressure room or a heating roomJust take the watchband and fill out the inspection form in the mail room
- 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: Vacuum table refers to the vacuum or pressure gauge?
- In fact, the vacuum meter, as the name suggests, is the reading of the vacuum. Here's a brief look at all the pressures:G P (table): pressure from pressure gauge read, it is the relative pressure by the atmospheric pressure as the benchmark value.Absolute pressure P (absolute): the actual pressure value based on absolute vacuum.The relationship between the absolute pressure gauge,P (absolute) =P (atmospheric pressure) +P (table)If the P (must) <P (atmospheric pressure), P (table) = - (P - P, the atmospheric pressure is lower than the vast) pressure gauge called vacuum. The higher the vacuum, the smaller the pressure.
- 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
- The pressure gauge common breakdown has following four points:1, the needle does not move. That is, when the pressure is raised, the indicator of the pressure gauge does not move.Cause analysis: Cock cock, not open; pressure gauge connection pipe or water pipe blockage; the pointer and the central shaft is loose or pointer stuck.2, pointer jitter.Cause analysis: hairspring damage; plug or trap local channel is blocked; both ends of a center shaft bending, two ends of the shaft rotation is not concentric.3, the pointer can not return to zero when there is no pressure.Analysis of reasons: spring tube permanent deformation, loss of flexibility; pointer and center axis loose or pointer stuck; plug, pressure gauge connecting pipe or water retaining pipe channel blocked.4 、 the instructions are incorrect and exceed the allowable error.Cause analysis: mainly due to the spring tube due to high temperature and overload or excessive deformation; gear wear loose; balance disorder; plug leakage.
- Q: How do you see a vacuum gauge?
- The units on the vacuum pressure gauge are bar, MPa, kPa, and the readings are mainly visible;The vacuum meter is divided into pressure vacuum meter and vacuum pressure gauge. Vacuum pressure gauge: Instrument Based on atmospheric pressure for measuring less than atmospheric pressure. Pressure vacuum meter: an instrument based on atmospheric pressure for measuring greater than or less than atmospheric pressure.There are two ways of expressing pressure. One is the absolute pressure, which is called absolute pressure, and the other is the pressure expressed on the basis of atmospheric pressure, which is called relative pressure. Since the pressure measured by most pressure gauges is relative pressure, the relative pressure is also called the gauge pressure. When the absolute pressure is less than the atmospheric pressure, the absolute pressure in the container is less than the value of one atmospheric pressure. Vacuum".They are as follows: the relationship between the absolute pressure = + atmospheric pressure relative pressure; vacuum degree = atmospheric pressure and absolute pressure; pressure units in China legal Pa (N/ m), known as Pascal, referred to as the PA. Since this unit is too small, it often uses its 10^6 times unit MPa (Zhao Pa).
- Q: Excuse me, where can I check the pressure gauge in Chongqing?
- Local metrology Bureau, if you know, manufacturers can also be tested
