Cleaning method of diaphragm pressure gauge
Cleaning method of diaphragm pressure gauge
After the diaphragm pressure gauge is used for a period of time, because the working environment of the diaphragm pressure gauge is various, or the wind, sun, rain, or the intrusion and corrosion of various media, the various parts of the diaphragm pressure gauge will be dirty. If it is dirty or corroded, the tested diaphragm pressure gauge should be cleaned before the calibration of the diaphragm pressure gauge.
Correct cleaning of diaphragm pressure gauge:
. If there is dirt in the pressure guide hole of the diaphragm pressure gauge connector, you can use a needle tube to inject gasoline into the guide tube, shake it, and then shake it out. Repeat several times to clean it.
Second, if there is dust accumulation in the diaphragm pressure gauge case, you can remove the cover, turn it upside down to get the dust out, and then use air to blow the remaining ash clean.
Third, if there is dust on the pressure gauge glass, the dirt will affect the reading of the diaphragm pressure gauge. You can clean the glass with clean water or use a cotton swab or cotton cloth to wipe the temperature with alcohol.
Fourth, due to the corrosion of corrosive gas, the diaphragm pressure gauge joint may be rusted, which will affect the installation of the diaphragm pressure gauge. At this time, it can be immersed in gasoline for washing and rust removal, or it can be passed through with the corresponding threaded die. Remove rust on the threads.
