- Q: Want to buy a pressure gauge, but do not know how to determine the pressure gauge model, you can only measure the size of the dial and then the size of the thread, there is no master pointing out the pressure gauge model specifications?
- Y watch case diameter: 406080100150Y40 China thread size 10*1 imports G1/8 ZG1/8 1/8NPTY60 China thread size is 14*1.5, import G1/4 ZG1/4 1/4NPTY100 China thread size 20*1.5 imports G1/2 ZG1/2 1/2NPTY150 and Y100 are the sameYX stands for electric contact pressure gaugesAnyway, the pressure gauge has its own plant numberJust for reference, I hope it will help youI corrected my friend YX on the floor. It stands for an electric contact. The pressure gauge doesn't mean axial
- Q: I want to use a frequency converter and a remote pressure gauge to control a submersible pump, using the on-off control, constant pressure water supply, how to connect and set up
- It is not suitable to control the frequency converter directly with the contacts of the remote pressure gauge. First of all, the contact jitter, will damage the inverter, and secondly, the number of contacts is not enough.The remote contact signal shall be first entered into the PLC. After finishing, the starting signal of the frequency converter shall be uniformly sent to the PLC. PLC can judge or delay method to control the frequency converter start and stop pump action, to achieve not only switch control water pump, but also soft soft stop pump effect. As for the wiring, relatively simple, PLC contact is connected to the frequency converter to start, stop contact. Of course, the water pump protection circuit is completed. Logical control is done by PLC.
- Q: The pressure gauge is red, yellow and green to indicate the pressure. When the needle points to the green area, what does it mean?
- The pointer in the green area or yellow area represents the extinguisher pressure enough to be used properly. In the red area, it's time to change.
- Q: How to use the car fuel pressure gauge?
- Usage method:(1) start the engine and switch to the normal operating temperature, turn off the engine, and then remove all the spark plugs when the engine is stopped;(2) the solar term valve is fully opened, the pressure gauge connecting head is pressed on the spark plug on;(3) use a motor to rotate the engine at 100 150r / min speed for 3 to 5 seconds. At this point, the pointer on the instrument will gradually rise, to a certain value that will stop, at this point the indicator value is the compression pressure of the cylinder;(4) press the button to make the pointer zero;(5) repeat the measurement 2~3 times according to the above procedures to improve the measurement accuracy.(6) general car cylinder pressure >0.9MPa and delta <8% (pressure of each cylinder, gasoline engine cylinder average pressure of not more than 8%).If the measured value is smaller than the specified value, and the intake system is normal, it can show that the cylinder and piston, cylinder head leakage, the original cylinder, piston, valve, piston ring wear, ablation and other undesirable situation. If the measured value is greater than the specified value, and the intake and exhaust system is normal, the possible cause is the serious carbon deposition in the combustion chamber.
- Q: Can the pressure meter read on the computer?
- The pressure transducer is used to change the pressure value to an electrical signal. The pressure value can be read on the computer through the PLC
- Q: What's the cylinder pressure gauge for?
- Measurement of rigid pressure, not more than 7, just lift the rigid cap
- Q: The pointer always points to the 0.5bar seismic pressure gauge, can not return to zero, the free end inside the broken? What's the reason then? Is the pressure too great?
- Proof above the table generally have a rubber plug, use is to cut with the atmosphere. If you are not cut, long time work, the pressure in the case. When the pressure is released in the form of discharge after the shell pressure, so just. You put a rubber plug off, if not back to zero that is bad.Yes, it's not rubber. It's a small valveThe tables are required to be installed vertically or near vertical and sealed when removed
- Q: What do you think of the pressure gauges with snow?
- There are two scale tables and multi scale forms in the air conditioning snow scale. We usually read the outer ring scale, and the other scales have the following indication, which represents the evaporation pressure of refrigerants under different refrigerants.?The outer ring (black scale) for pressure values, in the 2 circle (red scale) are a number of snow (R22, R12) corresponding to the temperature value.
- Q: Which circle should I watch with R22 plus, and which lap should I watch with the additional 410A?
- Look at the same place! Just the pressure is different! R410A pressure is higher than R22! Look at the outermost black circle! R22 from 4.5 to 5Kgcm2. R410A added 7.5 to 8KG/cm2 is almost the same!! No matter what refrigerant is different, only the pressure will not change.
- Q: How to choose a pressure gauge?
- A digital or a pointer is a manometerWorking environment, vibration proof, stainless steel...Accuracy classMeasuring range, how many MPA?Dial diameter
