Binary pressure packaging (binary packaging) refers to a type of pressure packaging system in which the propellant and the propellant are separately stored in two isolated units in the same packaging container, and the propellant is released from the packaging in a predetermined form by the energy (pressure) provided by the propellant during use. It has the advantages of environmental protection, high hygiene level, and solving problems such as raw material corrosion of tanks and gas-liquid incompatibility. Ordinary aerosol filling is the process of combining a propellant with a material, filling it in a container, and using a fluid stored under high pressure to push another fluid out of the spray can. This set of equipment has been widely used in industries such as medicine, hygiene, fire protection, and daily chemical industry, such as air fresheners, insecticides, disinfectants, household fire extinguishers, and computer cleaning agents.

The common faults and solutions of binary aerosol filling machines are as follows:

1. Inflator head leakage:

Reason: The rubber gasket at the bottom of the inflation nozzle is damaged, there are debris or damaged gaskets on the PTFE gasket in the inflation head, and the sealing ring of the inflation head is damaged.

Solution: Replace the rubber gasket, remove debris or replace the gasket, and replace the sealing ring.

2. Inflatable head does not reset:

Reason: The throttle adjustment elbow on the small cylinder of the inflation head is too small or tightly closed, the inflation head platform is too high, the foot valve is leaking air, and the gas metering cylinder signal valve is leaking air.

Solution: Increase the inflation head throttle adjustment elbow, adjust the height of the platform, replace the foot valve, and replace the signal valve.

3. Inaccurate filling volume:

Reason: Unstable compressed air pressure, damaged seals in the measuring cylinder, inaccurate opening and closing speed or angle of the filling valve.

Solution: Check and repair the air compressor, replace seals, regularly inspect and maintain the filling valve to ensure that its opening and closing speed and angle meet the requirements.

4. The device cannot start:

Reason: Power failure, motor malfunction, control circuit issue.

Solution: Check the power plug and wiring to ensure that the device is powered on; Replace the motor or repair the winding and other components of the motor; Use inspection tools to check and replace damaged circuit components.

5. Liquid leakage:

• Reason: Aging or damage of seals, pipeline rupture.

Solution: Replace with a new seal of the same model and replace the broken pipe section.

6. There is abnormal noise during operation:

Reason: Wear of mechanical components, lack of lubrication, and foreign objects entering the interior of the equipment.

Solution: Replace worn parts, add an appropriate amount of lubricating oil, and disassemble the equipment casing to remove foreign objects.
