Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as limiting to the invention.
A kind of pneumatic diaphragm pump is provided in embodiments of the invention, as shown in Figures 1 and 2, including valve actuating mechanism 1, center
Axle 2, and it is connected to the diaphragm 3 at the both ends of central shaft 2 for a pair, valve actuating mechanism 1 controls compressed gas-driven central shaft 2 back and forth to transport
Dynamic, the structure is the structure of existing pneumatic diaphragm pump.Wherein, in addition to an equalizing feature 4, equalizing feature 4 pass through a transmission
Mechanism 5 connects valve actuating mechanism 1 or central shaft 2, and synchronous with central shaft 2 and oppositely move.
In above-mentioned technical proposal, central shaft 2 valve actuating mechanism 1 the lower horizontal reciprocating motion of control, so as to drive a pair
Diaphragm 3 acts, and completes the action of the pumping liquid of pneumatic diaphragm pump.When central shaft 2 moves back and forth, due to the matter of central shaft 2
Amount and movement velocity generate the power for pointing to the direction of motion of central shaft 2, and this power causes the vibrations of pneumatic diaphragm pump.When pneumatic
Membrane pump runs at high speed when not reaching resonant frequency, because the deflecting frequency of central shaft 2 is very high, makes the power of different directions close to flat
Weighing apparatus, so as to alleviate the vibrations of pneumatic diaphragm pump, but when pneumatic diaphragm pump low-speed running, this vibrations will show very much
Write.Above-described embodiment is realized reciprocal to central shaft 2 by increasing synchronous with a central shaft 2 and heterodromous equalizing feature 4
Power is offset caused by motion, so as to realize the technique effect for eliminating vibrations.
In a kind of preferred embodiment, equalizing feature 4 can be balance shaft, and balance shaft can be carried out parallel to central shaft 2
Set, and it is synchronous with central shaft 2 and oppositely move back and forth.
In further embodiment, the quality of balance shaft can be made identical with central shaft 2, when balance shaft and central shaft 2
Can be produced and the size identical power of central shaft 2 during the motion of identical velocity reversal.Brought so as to which the motion of central shaft 2 be completely eliminated
Vibrations.
In a kind of preferred embodiment, equalizing feature 4 can be pendulum, and pendulum is synchronous with central shaft and oppositely past
Physical pendulum moves.Pendulum can be set by the rotatable pendency of a rotating shaft, and transmission mechanism 5 can be past by the actuated by cams pendulum in rotating shaft
Physical pendulum moves.
In a kind of preferred embodiment, transmission mechanism 5 can be one second valve actuating mechanism, and the connection of the second valve actuating mechanism is matched somebody with somebody
Mechanism of qi structure 1.Second valve actuating mechanism can be formed and the reverse control of central shaft 2 to equalizing feature 4.
In a kind of preferred embodiment, transmission mechanism 5 can be a drag link mechanism, and drag link mechanism connects central shaft 2.When
Drag link mechanism promotes the counter motion of equalizing feature 4 to realize power caused by centre of equilibrium axle 2 when central shaft 2 moves back and forth.
In a kind of preferred embodiment, as shown in figure 3, when transmission mechanism 5 is the second valve actuating mechanism, it is also settable
One speed measuring device 6, the connection central shaft 2 of speed measuring device 6 and transmission mechanism 5, the movement velocity of the inspection center's axle 2 of speed measuring device 6, when
Transmission mechanism 5 is controlled to be stopped when the movement velocity of central shaft 2 is more than a threshold value.The embodiment makes equalizing feature 4 only exist
Work during pneumatic diaphragm pump low-speed running, be then stopped when pneumatic diaphragm pump runs at high speed, so as to reduce because of equalizing feature 4
The power of consumption in operation, improve the operating efficiency of pneumatic diaphragm pump.
In further embodiment, speed measuring device 6 can also connect valve actuating mechanism 1 or compressed gas source (not in figure
Show), because the speed of pneumatic diaphragm pump can be controlled by bleed pressure, therefore detect valve actuating mechanism 1 or compressed gas source
Pressure can obtain the movement velocity of central shaft 2.
In further embodiment, a magnetic valve can be set, speed measuring device 6 connects the magnetic valve 61, when needs make
Magnetic valve 61 need to be only turned off when equalizing feature 4 is stopped, you can the second valve actuating mechanism is stopped, so that equalizing feature
4 are stopped.
In further embodiment, may also include a storage element 7, to store the detected value of speed measuring device 6 with
The mapping table of the running speed of pneumatic diaphragm pump, when speed measuring device 6 obtains detected value, in a kind of preferred embodiment
In, the pneumatic diaphragm for corresponding to detected value can be inquired about in storage element 7 according to the detected value of speed measuring device 6 by a control device 8
The running speed of pump, and then judge the running speed of the pneumatic diaphragm pump of inquiry acquisition whether more than upper by control device 8 again
State threshold value, above-mentioned threshold value can be stored in control device 8, also can be independent be stored in a storage element.
In a preferred embodiment, storage element 7 can be formed by storage chip or decoding circuit, further
Embodiment in, storage element 7 can provide a write-in interface 71, be write to connect external equipment into the storage element 7
