Instrument characteristics
Operation alert:
1, the operator should carefully read the product manual before using the equipment, master the safety knowledge of flammable gas use, and take appropriate safety precautions; Only after confirming that there is no gas leak
Carry out this experiment.
2. If gas leakage is found, the test should be stopped immediately. At this time, it is forbidden to light the fire source and turn on the power switch. The doors and Windows of the test equipment and the laboratory should be opened to allow the gas to be discharged to the outside; In the case of less gas leakage
Under, the exhaust fan can be turned on to discharge flammable gas.
3, before opening the air source, the pressure and flow regulation valve should be adjusted to the lower limit, and then open the total valve of the gas cylinder, and slowly adjust the gas pressure and flow to the required value; If the pressure and flow are opened to a large extent, you can
When it can be opened, all the liquid in the U-tube is discharged, leading to the gas leak.
4. If different gases are used before and after, the corresponding pressure reducing valve should be selected, and the gas remaining in the distribution pipe should be drained to avoid the danger of mixing different gases.
5. At the end of the test, close the valve of the gas cylinder first, let the Bunsen lamp continue to burn, and close the remaining valves when the gas in the tube is burned.
6, often check the sealing performance of the gas pipeline and the connection, if the pipeline aging, should be replaced in time to ensure safety.
7, regularly to the parts of the instrument lubricating oil, so as not to lose oil parts can not move and affect the normal use.
