To explain to you about the cleaning and corrosion resistance of diaphragm pressure gauge

How to clean stainless steel diaphragm pressure gauge correctly?

Stainless steel diaphragm pressure gauges for measuring corrosive, high temperature, high viscosity, easy to crystallization, easy solidified, have suspended solid medium pressure, in addition, to prevent the measured medium directly into the universal pressure gauge, prevent sediment accumulation, and easy to clean, need to be adopted by the diaphragm diaphragm table of isolator and universal pressure gauge.

1. Clean the pilot hole of the joint

Pressure gauge and equipment on the joint between the guide hole, if the pilot holes were blocked all kinds of fine dust and oil, cannot work normally, so frequent joint pilot hole cleaning, washing, first by the needle into the hole injection gasoline, gently shaking, make the oil soluble in gasoline, and then make gasoline all splash, repeat several times.

2. Clean the shell and interior

In order to protect the diaphragm pressure gauges, in its external useful materials watchcase, internal dust accumulation on the surface, when cleaning, please remove the diaphragm pressure gauge shell, and then gently will reverse pressure gauges, discharge of dust inside, and then use the appropriate tool to watch in the dust, dust, and then, on the cotton yarn with a small amount of alcohol, clean the glass clean.

3. Clean the rust

When the metal parts of the diaphragm pressure gauge rust, it is necessary to wash the part immersed in gasoline, but if the thread of the joint is rusty, please use the appropriate thread teeth for rust prevention, remove the rust on the diaphragm pressure gauge, make it dry, and further implement rust protection.

If you do not clean the diaphragm pressure gauge, the dust and dirt above the shell will block the reading value, can not correctly know the current pressure value, in addition, rust, dust, oil and other will also damage the quality of good, low price diaphragm pressure gauge, so be sure to regularly clean the diaphragm pressure gauge in the correct way.

Stainless steel diaphragm pressure gauge shell how anti-corrosion?

1, all stainless steel pressure gauge in the use of corrosive gases in the environment, in order to extend the life of the pressure gauge, it is recommended to apply PTFE on the shell.

2. When the ambient humidity is high, in order to prevent the moisture of the stainless steel pressure gauge from entering the table, it is recommended to improve the protection level of the cover plate and improve the life of the pressure gauge.

Anticorrosion of liquid contact part:

1, for the general corrosive medium, stainless steel elastic ability to withstand 1 -- 2 years of corrosion, stainless steel manometer price can choose the general stainless steel manometer, installation, shorten the pressure guide tube, if necessary, the buffer coil change to buffer tank, to prevent impurities blocked.

2, all stainless steel pressure gauge if there is a medium for the purpose of stainless steel and copper corrosion, can change the buffer tank to isolation tank, adding corrosion resistant stainless steel pressure gauge of the spacer, lyophobic kinds can choose according to the nature of the measured medium, but try to use no more than half of metamorphism, ordinary spacer inapplicable, can use fluorine chlorine oil as a spacer, but the price is higher, Therefore, it is necessary to reduce the isolation tank and recover the fluorine oil for reuse during disassembly and assembly.

3, diaphragm pressure gauges can be used, there are molybdenum stainless steel, with methyl silicone oil transfer between plate and ballistic pipe pressure, the minimum range can reach 0-100 kpa, if material is not resistant to, may add F46 (PVF) plate, but the instrument sensitivity decreased, also can be directly to F46 used as a separator, but please note that the permeability of medium, Use fluorine oil as transfer fluid for high temperature and oil-free medium.
