How to use the special pump for electric vehicles?
Align the mouth of the inflator with the mouth of the electric tire and press down. There is a valve on the mouth of the inflator. Break it over and fix the mouth of the inflator on the mouth of the tire. Unplug the mouth of the pump.
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. Now the most common pump is made of stainless steel, mainly because stainless steel has strong oxidation resistance, long service life, not easy to rust, anti-corrosion, not easy to deform, lead-free safety, high hardness, wear resistance and other advantages, durable, Widely used in various balls, bicycles, motorcycles, etc. 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 principle of the old-fashioned leather bowl pump: there is a gap between the piston of the pump and the wall of the cylinder, and there is a concave rubber bowl on the piston. When the piston is pulled up, the volume of air under the piston increases, the pressure decreases, and the piston The air above is squeezed from around the rubber bowl to the bottom. When the piston is pressed down, the volume of air under the piston is reduced and the pressure is increased, so that the rubber bowl is pressed against the cylinder wall to prevent the air from leaking to the top of the piston, and the piston is continued to be pressed down. , When the air pressure is enough to push the valve core of the tire, the compressed air enters the tire. At the same time, the air outside the cylinder enters the top of the piston from the gap at the upper end of the cylinder.
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.
