1. How to slow down a gas meter

If a household uses a small diaphragm meter, water can be injected into the outer chamber for backflow, and the resistance of water affects the rotation of the machine. Inheriting wisdom allows the meter to run slowly without affecting the flow rate. If a large flow meter can use a leak detection method that ignores small flow rates to steal gas.

2. There is only one flow meter in the CNG truck unloading station, and the gas loss is relatively high. Please help analyze the cause of the gas loss on Baidu ..

It may also be a problem with the accuracy of the flow meter. If there is no leakage, check if the flow meter is accurate

4. Perfectly solve gas path leakage, blockage, and pollution? Look here! The solutions to gas chromatography system faults mainly include three aspects: gas leakage, blockage, and pollution, which can be solved through targeted inspections and clever measures.

1. Reasons for gas path leakage: loose gas path joints, cracked pipelines in the gas path, failure to add suitable gaskets, internal leakage of gas path valves, etc. Inspection method: A-level leak test: After the gas source is turned on and stabilized, listen for any faint sound of gas running through the various pipelines and valve joints where the gas path flows. Alternatively, when the flow rate of the flow path is maximized, soap water can be used to gradually test for the presence of bubbles at each joint. B-level leakage test: Block the outlet of the gas path and observe the rotor inside the flow meter in the gas path. If it can slowly decrease to zero, then the B-level leakage test is qualified; If the rotor cannot be low

ered to zero, carefully observe each joint with soapy water until the leakage point is found. C-level leakage test: Block the gas outlet and observe the system pressure gauge. There should be no drop of more than 5kPa (equivalent to 0.05kgf/cm2) within half an hour. At this time, the system pressure should be above 0.25MPa (equivalent to 2.5kgf/cm2). If necessary, a 0.5 level standard pressure gauge can be connected externally at the system outlet to read the pressure change. Exclusion method: Joint leakage: Check if the joint gasket is suitable, annealed, and free of scratches. Ensure that the joint sealing area is clean, tidy, smooth, and free of dirt. When assembling the joints, align them with each other. First, tighten the joint roughly by hand, and then use a wrench to tighten it appropriately. For joints with plastic, rubber, or PTFE gaskets, the pressure should not be too high; For joints with metal gaskets, the pressure can be appropriately increased to ensure no air leakage. Narrowing down the range of gas leakage: When it is confirmed that there is a leak in the gas system, the method of blocking or closing the gas path in sections can be used to narrow down the range of gas leakage.

2. Reasons for gas path blockage: blockage of gas path filter joint, problems with stabilizing valve, tight column filling, blockage of injector, damage to flow control valve components, etc. Inspection method: Flow cannot be adjusted: Visual inspection: Check if there is any obvious air leakage sound in the instrument system. Leak detection: After hearing a leak sound, you can gradually locate it according to the direction of the sound, and use soap solution to apply to further determine the location of the leak.
