Problems with the pressure gauge
Thread Content
What is the specific purpose of the oil contained within the pressure gauge dial? Under what circumstances should a pressure gauge be filled with sealing fluid? What is the purpose of the horizontal cylinder between the pressure gauge and the sealing fluid?
Its function is as mentioned above: to prevent the hands of the watch from being damaged. .
The oil-filled pressure gauge is designed to cope with harsh operating conditions, offering significant cushioning effects, especially against vibrations in the medium being measured and in the surrounding environment. By filling the tank with oil, it lubricates the components inside the machine, thereby extending the service life of the instruments.
1. The oil contained in the pressure gauge is a damping oil, which is primarily used in harsh conditions such as those with high levels of vibration. 2. Is the liquid seal mentioned by the poster the isolation tank? Is it the isolation fluid added inside that serves to prevent freezing? (My own opinion might be wrong.) 3. I didn’t pay much attention to point 3.
A pressure gauge with oil inside the dial is a shock-absorbing pressure gauge.
Keep it shockproof! Explain the horizontal cylinder clearly; it would be best to have photos.
In my opinion, it is mainly to protect the pressure gauge; refueling is primarily aimed at protecting the pointer of the pressure gauge
Diaphragm shock-resistant pressure gauge, with silicone oil inside.
It’s the shock-resistant pressure gauge, something that protects the pressure gauge; I agree with the view from the fourth floor
If the inlet and outlet of a positive displacement pump experience significant vibration, a pressure gauge for flushing oil needs to be installed, mainly to prevent vibration. As is commonly used in slide vane pumps. :lol
It provides lubrication for the components inside the machine, and at the same time extends the service life of the instruments
Buffering and shock absorption are just one aspect; what’s important is isolation. The substance inside the tanks is an isolating fluid, and there is an isolating fluid system in the device, which is pumped to various points where instruments are located. Not all pressure gauges require an isolating fluid – it depends on the medium and the surrounding environment.
It is generally used in environments with significant vibration for shock protection
