Description
Technical Field
The utility model relates to a bidirectional piston water-cooling high-pressure air pump.
Background
The working principle of the high-pressure air pump is as follows: the engine drives the air pump crankshaft through two V-belts, so as to drive the piston to inflate, and the inflated air is guided into the air storage cylinder through the air guide pipe. On the other hand, the air cylinder guides the air in the air cylinder into a pressure regulating valve fixed on the air pump through an air guide pipe, so that the air pressure in the air cylinder is controlled. When the air pressure in the air cylinder does not reach the pressure set by the pressure regulating valve, the air entering the pressure regulating valve from the air cylinder cannot jack the valve of the pressure regulating valve; when the air pressure in the air reservoir reaches the pressure set by the pressure regulating valve, the air entering the pressure regulating valve from the air reservoir jacks the valve of the pressure regulating valve, enters the air passage communicated with the pressure regulating valve in the air pump, and controls the air inlet of the air pump to be normally open through the air passage, so that the air pump runs under the idle load, and the aims of reducing power loss and protecting the air pump are fulfilled. When the air pressure in the air reservoir is lower than the pressure set by the pressure regulating valve due to loss, the valve in the pressure regulating valve is reset by the return spring, the control air path of the air pump is cut off, and the air pump starts pumping again. The principle is the simplest air pump working mechanism, but when some air pumps requiring high pressure or ultrahigh pressure work, two sets of power systems are adopted in a common structure to provide power for a low-pressure pump and a high-pressure pump, and the structure not only consumes high energy, but also is easy to damage due to the complexity of structural parts.
