The present invention takes full advantage of pressurized air as the particular characteristic of driving medium, and special structural design, makes it have outstanding energy enlarge-effect, i.e. energy synergistic effect.
And several such pneumatic motors are in parallel or be cascaded, and form one group or several groups, and the effect that its energy amplifies will be more obvious.Simultaneously, according to the program that sets, control is the air flue switch of several or several groups pneumatic motors wherein, reaches the control to mechanical separator speed, i.e. infinite variable speed realization, and these all are that other pneumatic motors are not available.
Because this pneumatic motor where necessary, rotor can be changed mutually, so suction port and slip choke piece sometimes also can change on shape and position accordingly.Removing the pneumatic control assembly is outside the common elements, and other assembly is the main member of a rotary unit of this pneumatic motor, and a plurality of such rotary unit serial or parallel connection forms a pneumatic unit with energy synergistic effect together.And several groups of so pneumatic unit serial or parallel connections act on a bit together or face on the time, by the input quantity of control high-pressure air, realize infinite variable speed purpose with output and rotating speed that the pneumatic control assembly is controlled the external power of pneumatic unit according to the program (namely according to pneumatic group of machinery that drives operational situation at that time) that sets.
Because being multi-cylinder, this pneumatic unit organizes linkage type (single group is good), so following only with structure and the working principle of three groups of types of three cylinders in order to this pneumatic unit to be described more.
Three cylinders of A group are respectively A1, A2, A3, and three cylinders of B group are respectively B1, B2, B3, and three cylinders of C group are respectively C1, C2, C3.
When high-pressure air after suction tude 1 enters the pneumatic control assembly, can be according to the machinery that drives operational situation at that time by air-guide branch pipe 3 injected gas in the corresponding cylinder.Such as, machinery at that time is state of rest, the pneumatic control assembly can be according to the program that sets by air-guide branch pipe through suction port injected gas in the cylinder of A1, the B1 of A, B, C group, C1, and be in the circular cylinder fixing traverse between suction port and the relief opening (or take slip choke piece as active clapboard) as the starting point of piston, be the suction port in the cylinder between dividing plate and piston.After in high-pressure air enters cylinder and since fixing traverse or the active clapboard made of slip choke piece stop that the high-pressure air in the cylinder can only the pushing piston rotation.When piston rotates 1/3 cylinder after week, the pneumatic control assembly can be according to the program stopped that sets air feed (under the effect of the expansive force of gas, piston can continue the direction rotation to relief opening) in A1, B1, the C1 cylinder.Simultaneously, A2, B2, piston in the C2 cylinder is on the starting point, so beginning is to A2, B2, air feed in the C2 cylinder, work as A2, B2, after piston in the C2 cylinder rotated for 1/3 week, the pneumatic control assembly can be according to the program that sets, stop to A2, B2, air feed in the C2 cylinder, but beginning is to A3, B3, air feed in the cylinder of C3, and this moment A3, B3, piston in the C3 cylinder also is on the starting point, at fixing traverse (or piston dividing plate, be rotary-piston) effect under, high-pressure air can only promote A3, B3, piston in the C3 cylinder rotates to relief opening, when rotating to 1/3 cylinder after week, A1, B1, piston in the C1 cylinder just in time rotates a circle and has got back to again on the starting point, the pneumatic control total performance can stop A3, B3, the air feed of C3, and turn to A1, B1, air feed in the cylinder of C1 carries out next one circulation.
A complete process with Pneumatic rotary circulation of energy synergistic effect that Here it is.
And electrodeless variable-speed is to say: after the rotating speed of the equipment that is driven reaches the scope of program setting, the pneumatic control assembly can be according to program stopped to one group of pneumatic unit air feed wherein, such as the A group, rotating speed can improve in remaining like this two groups of situations that air demand is constant within the unit time.By that analogy, until the output energy reaches balance with the energy that needs or only remaining last organized pneumatic unit work, this is the speed-raising of electrodeless variable-speed, and reduction of speed 1. stops air feed, and the break of 2. leaving behind can be realized.Speed-raising is for repeating the speed-raising process again.
