Why does the respirator inflation pump have the problem of biting the cylinder?

Air respirator inflation pump is an indispensable equipment in industries such as firefighting and diving, used to provide safe and reliable compressed air. However, during use, sometimes there may be issues with cylinder jamming, which not only affects the normal operation of the equipment but may also pose a threat to the safety of the user. The following will provide a detailed analysis of the causes of cylinder blockage in the respirator inflation pump:

1. Lubricating oil issue

-Insufficient or poor quality lubricating oil: Lubricating oil is crucial for the normal operation of the compressor. If the lubricating oil is insufficient or inferior lubricating oil is used, it will cause an increase in friction between the cylinder and the piston, leading to cylinder jamming.

-Lubricating oil deterioration or contamination: Failure to replace lubricating oil for a long time, or impurities from the working environment entering the lubricating oil system, may cause lubricating oil deterioration or contamination, affecting its lubrication effect.

2. * * Cooling system malfunction

-Poor cooling: The compressor generates a large amount of heat during operation. If the cooling system malfunctions, such as insufficient coolant or damaged cooling fans, it can cause the cylinder temperature to become too high, resulting in a decrease in the gap between the cylinder and piston, and causing cylinder jamming.

3. Wear of cylinder and piston

-Wear caused by long-term use: As the usage time increases, both the cylinder and piston will gradually wear out. When the wear is severe, the gap between the two will change, resulting in poor movement and even cylinder jamming [^ 3 ^].

-Foreign objects entering the cylinder: If there is dust or other impurities in the working environment and these impurities enter the cylinder, they can cause damage to the cylinder and piston, increasing the risk of cylinder jamming.

4. Improper operation

Incorrect startup sequence * *: The correct startup sequence is crucial for protecting the compressor. If the preparation work is not fully checked before starting, or if the operation is improper during the starting process, it may lead to cylinder jamming problems [^ 5 ^].

-Overload operation: Prolonged operation of the compressor under high load can increase its wear rate and also easily lead to high cylinder temperature, resulting in cylinder jamming.

5. * * Electrical system malfunction

-Unstable Voltage: Unstable voltage not only affects the normal start-up and operation of the compressor, but may also cause the motor to overheat, indirectly leading to cylinder jamming problems.

-Damage to electrical components: If electrical components such as contactors and relays fail, it may cause the compressor to fail to start or stop normally, leading to a series of chain reactions, including cylinder jamming.

6. * * Transmission device malfunction

-Belt looseness or breakage: If the transmission belt is too loose or breaks, it can cause unstable compressor speed and increase the risk of cylinder jamming.

-Bearing damage: Bearings are important components that connect the motor and compressor. If the bearings are damaged, it can cause the compressor to operate poorly and even result in cylinder jamming [^ 3 ^].

7. * * Environmental factors

-Excessive or insufficient temperature: Extreme temperature conditions can affect the performance of lubricating oil and the heat dissipation effect of the compressor, thereby increasing the possibility of cylinder jamming.

-Excessive humidity: In high humidity environments, water vapor in the air can easily condense into water droplets and adhere to the cylinder wall, causing rusting or corrosion of the cylinder and leading to cylinder jamming.

8. * * Maintenance is not timely

-Lack of regular maintenance: Regular maintenance can detect and solve potential problems in a timely manner, reducing the probability of malfunctions. If this point is ignored, it can easily lead to small problems accumulating into big problems, ultimately causing cylinder jamming.

-Poor cleaning: Dust and impurities inside the compressor need to be cleaned regularly, otherwise it will affect its normal operation and increase the risk of failure.

In addition, to avoid cylinder jamming issues, the following measures can be taken:

Regular inspection and maintenance * *: Regularly inspect various components of the compressor, including lubricating oil level, cooling system, electrical components, etc., to ensure that they are in good condition.

Use high-quality lubricating oil * *: Choose high-quality lubricating oil suitable for the compressor and replace it at regular intervals.

Keep the working environment clean * *: Try to minimize dust and other impurities in the environment around the compressor to prevent them from entering the cylinder.

Correct operation of compressor * *: Strictly follow the operating procedures to start and stop the compressor, avoiding overload operation.

Installing a voltage regulator * *: If the voltage is unstable, you can consider installing a voltage regulator to ensure power stability.

-Timely handling of faults: Once abnormal sounds or other signs of faults are found in the compressor, it should be stopped immediately for inspection and handling.

In short, there are various reasons for the cylinder sticking problem of the respirator inflation pump, including problems with the equipment itself, as well as external environmental factors and usage habits. By regular maintenance, reasonable use, and timely handling of faults, the incidence of cylinder jamming problems can be effectively reduced, ensuring the safe and stable operation of the equipment.
