- 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.
- This is very good, quack, I am now out of the machine installed, in the evening to give you a satisfactory answer, the best for me to keep
- Q:What do you think of the pressure gauge for portable pressure storage ABC dry powder extinguisher?
- The pointer is qualified in the green area. The red area indicates that the pressure is low and it needs stamping
- Q:The gas pressure reducer has two measuring ranges, one big and one small pressure gauges. What's the function of each? What's the meaning of a red line on some pressure gauges?
- The big one refers to the bottle pressure, that is to say, the inlet pressureSmall refers to the pressure of the outlet after decompression
- Q:What do you mean by "M20*1.5" in the pressure meter, M20 and 1.5 respectively?
- M20 is thread diameter, 1.5 is the tooth pitch, this size is the current domestic pressure gauge universal joint size.And M20*1.5, M16*1.5, M14*1.5, and so on
- 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:What do you think of the pressure gauges with snow?
- This table has a few laps scale, standard is temperature, there is the subject of pressure, there are usually several pressure scale, corresponding to different units, corresponding to the temperature is under the pressure of the refrigerant saturation temperature, should pay attention to and use the same model of refrigerant
- Q:I am doing water treatment works, water pump is connected with the back of my mechanical filter, know the maximum pressure pump working for 2.5MPa, so I want to be in place to install a water pump outlet pressure gauge, pressure gauge pressure range is how much?
- The maximum working pressure of the general pressure gauge is 2/3 of the range, and the 0-4Mpa is selected
- 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: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
- According to JJG52-1999, Bourdon tube, general pressure gauge, pressure vacuum gauge and vacuum gauge, 5.3.3.5, return error:For the same test point, the difference between the indication value after tapping the watch case at the step-up (or step-down) and the buck (or boost) testThe return error is the absolute value
- Q:What's the difference between a pressure gauge and a negative pressure meter?
- According to the type of pressure to be divided into negative pressure table, differential pressure gauge, positive pressure gauge, so the negative pressure gauge is only one kind of pressure gauge.Negative pressure meter measurement is relative to the local atmospheric pressure for negative pressure, negative pressure table, also known as vacuum pressure gauge, but conceptually there are some subtle differences, not here.If there is no special explanation, we generally say the pressure gauge defaults to the positive pressure meter.
