The piston type is directional, and the phase sequence protector must be installed. In case the circuit phase sequence changes, it will protect it and not work. The spiral type is good, it has no direction, the wiring direction is not specified, and the work is stable.
The piston type is directional, and the phase sequence protector must be installed. In case the circuit phase sequence changes, it will protect it and not work. The spiral type is good, it has no direction, the wiring direction is not specified, and the work is stable. After the suction valve of the piston engine is opened, the inertial force disappears and the pressure difference decreases quickly, but the suction process line is always lower than the atmospheric pressure line. The reason is that a certain pressure difference needs to be maintained to overcome the spring force and the suction pipe, the air filter, The resistance of the relief valve and the suction valve.
At the end of the suction process, as the linear velocity of the piston slows down, the airflow speed also decreases, so the air pressure in the cylinder rises again, until the pressure difference is reduced to the point where the spring force cannot be overcome, the suction valve is immediately closed, and the suction process ends. The next cycle is repeated.
The principle of the piston machine-After the driving machine is started, the crankshaft of the compressor is driven to rotate through the triangular tape, and the crank rod mechanism is converted into a piston to reciprocate in the cylinder. When the piston moves from the cover side to the shaft, the cylinder volume increases, the pressure in the cylinder is lower than the atmospheric pressure, and the outside air enters the cylinder through the filter and the suction valve.
After reaching the bottom dead center, the piston moves from the shaft side to the cover side, the suction valve is closed, the cylinder volume gradually decreases, the air in the cylinder is compressed, and the pressure rises. When the pressure reaches a certain value, the exhaust valve is pushed open. Compressed air enters the air storage tank through the pipeline, so that the compressor works repeatedly, continuously delivering compressed air to the air storage tank, so that the pressure in the tank gradually increases, so as to obtain the required compressed air.
