Liquefied Gas Cylinder Testing Equipment Use Precautions

Jul 10, 2017

1. Nitrogen interchange work

① after the bottle, the first surface of the cylinder cleaning, after the gas bottle through the bottle rack slowly rose to the transfer line position and translating to the nitrogen position;

② With the handle hose and bottle valve tightened, start the bottle valve, LPG Gas Cylinder Testing Equipments if the pressure is less than the specified value, then open the exhaust valve for gas discharge until the pressure is normal, this time the exhaust valve can be closed; if greater than the specified pressure Value, the cylinder should be sent to the residual gas processing station for the necessary treatment;

(3) start the pipe valve and release all the gas from the cylinder, then open the nitrogen valve, put the nitrogen into the bottle, turn off the pipe valve; open the exhaust valve to start the exhaust gas, until the gas pressure to normal pressure And then turn off the exhaust valve; then start the nitrogen pipe valve, LPG Gas Cylinder Testing Equipments the nitrogen into the bottle, turn off the nitrogen valve; open the exhaust valve, so that non-stop into the nitrogen, nitrogen exchange work is completed;

2, close the drain valve, open the nitrogen cylinder valve, LPG Gas Cylinder Testing Equipments adjust the pressure reducing valve to remove the nitrogen pressure of 0.4 MPa, open the nitrogen inflatable valve to the cylinder until the pressure rose to 0.4 MPa, then turn off the nitrogen inflatable valve, open The exhaust valve keeps the mixture in the cylinder.

3, repeat the second step 2-3 times. After all the gas in the cylinder is discharged, remove the connected high pressure hose for the next step.

4, unloading valve processing

(1) the gas bottle is sent to the designated position of the unloading valve, and the chuck is manually placed on the top (note: the chuck is adjustable according to the parameter), LPG Gas Cylinder Testing Equipments the clamping control valve is opened and the cylinder is stabilized;

② will release the valve open, the card head to rotate, then the bottle valve down, then the valve unloading treatment, and then turn off the clamping valve, the clamping system to release the cylinder; gas bottle to the cleaning Machine position, unloading valve to get.

5, cleaning operation

① to clean the gas bottle to the cleaning place, LPG Gas Cylinder Testing Equipments the bottle to promote the treatment, so that the bottle and the arch close to each other;

② start the washing machine control system, according to a certain angle flip, and let the cylinder bottle in the downward direction, so that the liquid slowly outflow. Start the top of the control system, the high pressure gun into the gas bottle. Open the washing machine, which allows the cleaning machine to clean the gas bottle work.

6, bottle thread detection

Check the valve thread with the ring gauge is normal.

Use the plug gauge to check whether the bottle thread is normal. LPG Gas Cylinder Testing Equipments Bottle thread does not normally need to use tapping tapping.

7, endoscopy

1 Connect the endoscope

2 Turn on the endoscope power supply

3 Insert the endoscope probe into the mouth of the cylinder

4 Open the endoscope switch. Observe the internal situation of the cylinder to see if there is a little corrosion, surface corrosion, and national standards.

8, shot blasting rust

1 to open the total power of the shot blasting machine

2 turn on the fan roller turn left and turn right.

3 manually add sand inside the sand machine until the shot blasting machine current is 7.

4 plug the natural gas cylinder plug, LPG Gas Cylinder Testing Equipments so that the bottom of the bottle bottle bottle back to push the cylinder to the shot blasting machine.

5 wait for the gas bottle shot blasting to complete a bottle.
