- Q: What is a negative pressure gauge?
- The negative pressure gauge should be another name for the vacuum meterVacuum meter: Instrument Based on atmospheric pressure for measuring less than atmospheric pressure.
- Q: Can you use the precision pressure gauge of level 0.25, measuring range (0~10) and MPa to verify the general pressure gauge of level 1, measuring range (0~6) MPa? Why?
- There is no problem with the standard meter. The measuring instrument should use a 0.05 stage piston pressure gauge
- Q: Detailed explanation of working principle of Bourdon tube pressure gauge
- Bourdon tube pressure gauge through the sensitive element in the table (Bourdon tube, bellows, bellows) of the elastic deformation, then the conversion mechanism of table movement will transfer to the pointer pressure distortion caused by pointer rotation to show pressure
- 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?
- 2.5MPa*3/2=3.75MPa, select the 0-4.0MPa pressure gaugeGenerally choose the maximum pressure of 1.5 times, and then according to the standard range can be selectedThe standard range is 1,, 1.6, 2.5, 4, 6, n times
- Q: The injection molding machine doesn't have pressure, what's wrong with it and the pressure gauge doesn't reflect it?
- 1 check the tank level first. Is it normal?2 then check to see if the oil pump motor has started yet3 check the outlet of the oil pump to see if there is any oil flowing outCan be judged to be missing oil motor failure or oil pump failure
- Q: What are the problems with the pressure meter?What are the good solutions to these problems in the pressure gauge?
- Summarize the common faults and causes the pressure gauge, in the operation of only the exchange, because of different brands and types of pressure gauges were different. Personal recommendation if there is a problem of replacement or return to the supplier, procurement of new products, and send check calibration analysis as follows:A pressure gauge without indication. Reason: 1, pressure pipe on the cut off valve does not open; 2, pipe plug; 3, spring tube joint too much dirt siltation and plug; 4, spring tube cracking; 5, the center gear and fan tooth wear too much, and is not engaged.Two, pointer shaking large. Reasons: 1, the pressure of the medium to be tested; 2, pressure gauge installation position of vibration
- Q: What is the range of use of a pressure gauge? Why is it at its measuring range of 1/3-2/3?
- 1, it is the characteristic of elastic element, at 1/3-2/3, the linear and accuracy of elastic element is best;2. To ensure that the maximum pressure is less than the overload pressure in the range of 2/3, for the sake of safety and instrument life;
- Q: Set up a factory. May I ask what equipment you need to build a pressure gauge factory?
- Is the professional calibration equipment, you Baidu will know, I am Nanjing Wanda instrument factory. Hope to help you.
- Q: There is no pressure gauge in the process of adding fluorine to the air conditioner
- Methods: fluoride 1. will be the first operation of air conditioning in the cooling mode, the fluoride mouth with Freon tank on one end of the tube with fluorine and fluoride, the other end tube (with fluoride thimble tube), installed in the low-voltage end of outdoor unit of air conditioner (suction tube) fluoride mouth. 2., open Freon tank plus fluorine valve on the mouth, can directly add fluorine to the air conditioning, fluorine amount of how much, should refer to the air conditioning nameplate marked "fluoride charge" for fluorine. Quantitative filling with scale. After the fluorine is finished, turn off the valve on the Freon tank and the fluorine nozzle, and let the air conditioner continue to operate. To observe the effect of air conditioning refrigeration, such as air conditioning to achieve normal cooling effect, low end remove outdoor machine (suction) plus fluoride mouth of fluoridation pipe, tighten the cap, and the mouth of the air conditioning fluoride can be used normally
- Q: Mainly inside these two laps, freon temperature is what, oh, do not understand, usually the original table, I see the MPa, this is not, thank you!
- The temperature of Freon refers to the saturation temperature of the corresponding freon refrigerant under this pressure corresponding to the pressure of the outer ring.
