The principle and structure of the pump
The principle of the pump is:
The pump is an air pump that sucks air into the storage area by pulling, and then injects or replenishes the air required by various tires and some balls by pushing. When using a pump, connect its air outlet to the valve of the bicycle tire. The function of the valve is to only allow air to enter the tire from the pump, and not allow the air to flow back into the pump from the tire.
The new outer tube sliding pump is the simplest one-way valve. When the outer tube is lifted up, the air will enter the air cylinder from the small hole on the middle sleeve at the lower end of the outer tube of the air cylinder. At this time, when the handle is pressed down, the air will enter the air cylinder through the one-way valve set at the top of the inner tube. The inner tube goes down the leather tube into the valve of the tire.
When the handle is lifted up for the second time, the one-way valve is closed, and when it is pressed down again, the air rushes through the one-way valve and enters the tire. This cycle back and forth, you can inflate the tires.
The characteristics of the pump are:
1. The inflator is suitable for inflating various balls and bicycles such as bicycles, basketballs, volleyballs, footballs, etc. Versatile, compact design and robust construction.
2. The high-pressure pump can be used for front and rear shock absorbers, and it can also be used as a general car-mounted mini pump.
3. In addition to changing the angle of the pumping hose at will, the joint can be rotated 360 degrees, which is convenient for pumping at any angle.
4. The quality of stainless steel pump is high, stainless steel has the advantages of strong oxidation resistance, long service life, not easy to rust, anti-corrosion, not easy to deform, lead-free safety, high hardness, wear resistance, etc., durable, widely used in various Balls, bicycles, motorcycles, etc.
