Blasting pipe installation procedure
1, check the charge and discharge holes at both ends of the inflatable head, head screw is intact, prevent leakage. Use compressed air to clean the threads and inner holes of the head.
2, the rupture of the piece of oil after the oil into the supervisor (division of the inner diameter, small holes in the installation of the rupture disc and the discharge head, the big hole installation of the activator and the charging head).
3, the short lead wire and the discharge head are connected, and the discharge head is installed. Measurement of the discharge head and the wall of the discharge head with a universal meter is conductive, not through the pass for qualified.
4, the activation device is connected with the wire and then apply the oil film rupture, in the activator on copper, in charge and install the pneumatic head.
5, using a universal meter to measure the resistance between the head and the discharge head
6, in the automatic hydraulic screwing machine screwing charging head, energy release head. Can also be used pneumatic pipe wrench.
7, using an ohm meter to test the value of the resistance between the head and the discharge head is normal. To detect whether the rupture disc and the tube wall are normal. Before the test, test contact, avoid accidents caused by static electricity.
Charging step
1, filling machine weight adjusted to the specified value, the pressure regulating valve to adjust the pressure of 5kg for refrigeration thermometer indicator lights, press the button to start the compressor refrigeration refrigeration.
2, will be fixed to the head of the gas station, open the valve on the inflatable shelf. Loosen the inflatable head valve thimble, release end tube gas, the inflator zero weight meter.
3, unscrew the inflator and exhaust valves, carbon dioxide gas slowly unscrew the liquid outlet valve, until completely open. The mist of carbon dioxide, close the exhaust valve. When the inflatable frame appears mist exhaust valve close the exhaust valve, carbon dioxide, and then to director of the natural gas, the intake valve closed, open the exhaust valve exhaust, to reduce charge temperature for charging.
4, once again unscrew the inflator and exhaust valves, see the mist of carbon dioxide ejected after closing the inflator and exhaust valves. Open the air intake valve frame, when the gas exhaust valve frame appear mist CO2, close the exhaust valve, press the button to start the inflatable inflator, until the inflator stops automatically, quickly closed the inflated frame inlet valve, inlet valve thimble screw inflating head. Loosen the air vent valve and drain the excess carbon dioxide.
5, remove the carbon dioxide pipe, the two ends of the tube were put into the bucket filled with water to detect whether the leak. No more than two bubbles per minute can be used. Put the tube on the assembly frame to avoid the load of the head and the head.
6, is strictly prohibited in advance connected to the Bao device. Transportation and operation should be cautious, to prevent knock, no high temperature exposure tube
