Adjustment of oil output and speed of pneumatic grease gun: the key role of working pressure

1. The relationship between working pressure and oil output performance
The working principle of pneumatic grease gun is to use compressed air to push butter or grease through the pipeline and finally inject it into the part that needs lubrication. In this process, working pressure plays a vital role. When the air pressure increases, the piston inside the grease gun will be subjected to greater thrust, thereby accelerating the flow of butter and increasing the oil output and speed. Conversely, reducing the air pressure will slow down the flow speed of butter and reduce the oil output.

2. Specific operation of adjusting the pressure gauge
In order to adjust the oil output and speed, we need to accurately adjust the pressure gauge on the grease gun. The specific operation steps are as follows:

Preparation stage:
First, make sure that the grease gun is in an oil-free state to avoid butter overflow during the adjustment process. At the same time, check whether the pointer of the pressure gauge is zero to ensure the accuracy of the adjustment.
Turn the adjustment knob:
Next, turn the adjustment knob on the pressure gauge clockwise or counterclockwise. Clockwise rotation increases air pressure, thereby increasing oil output and speed; counterclockwise rotation decreases air pressure, reducing oil output and speed. During the rotation process, you can observe the changes in the pointer of the barometer to determine whether the air pressure has reached the required value.
Stabilize the air pressure:
After adjusting the air pressure, you should wait for a while to allow the pressure inside the grease gun to stabilize. This ensures the stability of the oil output and speed and avoids fluctuations during operation.
Test the oil output effect:
Finally, perform an oil output test. Aim the grease gun at the test area and observe the outflow of butter. If the oil output and speed are as expected, the adjustment is successful; if there is still a deviation, you can repeat the above steps for fine-tuning.
III. Precautions and risk prevention
When adjusting the working pressure of the pneumatic grease gun, you need to pay attention to the following points:
Avoid excessive air pressure:
Although increasing air pressure can increase oil output and speed, excessive air pressure may cause the grease gun to overheat or damage. Therefore, when adjusting the air pressure, the upper limit value should be reasonably set according to actual needs.
Keep the grease gun clean:
Grease guns tend to accumulate dust and dirt during use, which can affect their normal operation. Therefore, before adjusting the air pressure, ensure the cleanliness of the grease gun inside and outside.
Regular inspection and maintenance:
Regular inspection and maintenance of the grease gun is key to ensure its long-term stable operation. This includes checking the accuracy of the air pressure gauge, replacing worn parts, and cleaning the grease gun.
Follow the operating instructions:
Different brands and models of pneumatic grease guns may have differences in operation. Therefore, before adjusting the air pressure, read the operating instructions carefully to ensure that the grease gun is operated correctly.
