Pneumatic grease guns are tools driven by compressed air. They are widely used in machinery, automobiles, agriculture and other industries to add grease (butter) to parts of mechanical equipment. Its working principle is to use compressed air to push the piston or gear to force the grease to be released from the grease gun. Therefore, pneumatic grease guns have strict requirements on the air source to ensure their normal operation and service life. The main air source requirements include the following aspects:
1. Air source pressure
Pneumatic grease guns usually require stable working air pressure. In general, the air source pressure should be between
Heavy duty pistol grip grease gun 6-8 bar (about 87-116 psi), and the specific pressure requirements depend on the model of the grease gun and the technical requirements of the manufacturer. Too low pressure will cause the grease gun to discharge oil unsmoothly or not work properly, while too high pressure may cause damage to the grease gun or excessive consumption of gas.
2. Air source flow rate
Pneumatic grease guns require a certain amount of air flow to ensure that they work quickly and effectively. The air source flow rate is usually required to be between 0.2-0.3 m³/min, and the specific flow rate depends on the model of the grease gun and the working requirements. If the air flow is insufficient, the grease gun may move slowly, affecting lubrication efficiency and user experience.
3. Air source quality
The quality of the air source is crucial. Pneumatic grease guns have high requirements for air cleanliness. If there are too many impurities such as moisture, oil mist, dust, etc. in the air source, it will cause corrosion, blockage or jamming of the equipment, thus affecting its service life and working effect. In order to ensure the quality of the air source, dryers and filters should be used to remove moisture and impurities in the air to ensure that the air is clean and dry.
4. Pipe size and connection
The size and connection quality of the air source pipeline will also directly affect the performance of the grease gun. Generally, the air pipe used should have a sufficient inner diameter to ensure unrestricted air flow and avoid pressure loss. The pipe joints should be tight and leak-free to avoid fluctuations in air source pressure. Generally, air pipes with an inner diameter of not less than 8 mm are more suitable.
5. Air source stability
A stable air source supply is the basis for ensuring the normal operation of the pneumatic grease gun. The air pressure should be kept stable to avoid incoherent action of the grease gun or failure to work as expected due to fluctuations in air source pressure. In addition, sudden interruption of the air source should be avoided during use to avoid affecting the production or operation progress.
6. Temperature requirements
During the use of the pneumatic grease gun, the temperature of the air source should also be kept in an appropriate range. Generally speaking, the air source temperature should be controlled between 5°C and 40°C. Too high or too low a temperature may affect the efficiency of the pneumatic grease gun or damage its internal components.
7. Safety measures
Since the pneumatic grease gun uses compressed air, the safety requirements for the air source are also very high. Safety devices such as safety valves and pressure gauges need to be configured in the air source system to ensure that the air source will not cause equipment damage or safety accidents due to excessive pressure.
Summary
In general, the air source requirements for pneumatic grease guns include appropriate air pressure, sufficient air flow, good air source quality, appropriate pipe size and connection, air source stability, and appropriate temperature. Only by meeting these requirements can the pneumatic grease gun maintain an efficient and stable working state and extend its service life.
