Multiple stroke), crank axle 25 is connect by deceleration mechanism 32 with motor 33.
The on both sides of the middle of wherein crank connecting link 21 is respectively provided with T-type cavity, can mitigate the weight of crank connecting link 21 in this way, subtract
The inertia impact that few crank connecting link 21 moves back and forth, improves the flexibility of movement.
A kind of course of work of plunger pump driving device compensated automatically of the present invention is as follows：Before work song is rotated with hand
Handle driving mechanism drives plunger 4 to move to position shown in Fig. 1, and makes the circular hole A17 (cylinder bodies 1 of cylinder body 1 through crank connecting link 21
Working chamber), the hydraulic chamber of right angle -7 inner cavity of hinged rubber pipe assembly and quantitative 8 pump head of diaphragm pump head be formed by closing work
Make chamber and drains air full of hydraulic oil Bing；
When work, motor 33 by two-stage synchronous pulley deceleration mechanism 32 drive crank axle 25 rotation (crank axle 25 it is several
What center is fixed in rack 31), crank axle 25 drives crank connecting link 21 that plunger 4 is driven to move reciprocatingly, and plunger 4 pushes away when moving ahead
Hydraulic oil liquid in dynamic closing working chamber moves ahead, and squeezes the diaphragm premutation shape of quantitative diaphragm pump head 8, quantitative diaphragm pump head 8
Dielectric cavity in medium be extruded；Hydraulic fluid pressure is set by level pressure overflow valve 5, extra hydraulic oil by level pressure overflow valve 5,
Spout hole 15, cavity 13 and the gap of crank connecting link 21 flow back to oil storage pool.The hydraulic pressure in closing working chamber is pulled when plunger 4 retracts
Fluid retracts so that concave change shape after the diaphragm of quantitative diaphragm pump head 8, medium are inhaled into the pump head dielectric cavity of quantitative diaphragm pump head 8.
It is negative pressure to be closed in back off procedure in working chamber, when plunger 4 return back to position shown in Fig. 1, since ladder mouth a2 is through bite type
Pipe fitting a10, hose 11, ferrule-type compression joint b27, damper 35 are connected with oil storage pool, under the action of negative pressure the liquid of oil storage pool
Pressure oil is inhaled into closing working chamber, during inhalation, in stepped hole a2,1 working chamber of stepped hole b3, stepped hole c9 and cylinder body
(circular hole A17) is communicated, and intercommunication inside stepped hole b3, stepped hole c9, deflector hole 12 and circular hole B18, constitutes internal diversion channel,
Since the internal diameter of circular hole B18 is much smaller than the internal diameter of circular hole A17, rollback flow is identical everywhere for closing working chamber when plunger 4 retracts, circle
The aperture of hole B18 is the 1/2~1/3 of the apertures circular hole A17, and the area ratio of circular hole A17 and circular hole B18 is 1/4~1/9, therefore ladder
Faster, thus negative pressure value is lower for flow velocity at hole c9 and circular hole B18 perforations, and circular hole B18 is through stepped hole c9, deflector hole 12, stepped hole
B3 and absorption fluid at circular hole A17 perforations, are able to quick repairing so that closing working chamber internal pressure tends to be balanced, to make
Repairing is more rapidly efficient, steady reliable.When closing working chamber by repairing, when internal pressure gradually rises to an atmospheric pressure,
Automatic oil replenishing process terminates, and plunger 4 starts to move ahead, into next working cycles.
When plunger 4 is forwarded to certain position, stepped hole a2 is connected with oil suction plane 24, and plunger 4 continues to move ahead, arch gap
30 volume of chamber becomes larger, thus arch gap chamber 30 is through ferrule-type compression joint a10, hose 11, ferrule-type compression joint b27, damper
35 draw fluid from oil storage pool；Fluid enters the pin hole 28 of plunger 4 through crescent shape gap, enters column by the through-hole of plunger pin 6
In the pin hole 28 of the plug pin other end, after more than 4 forward travel of plunger, the full fluid of the storage of pin hole 28 can be to 6 both ends outer circle of plunger pin
Face faying face carries out infiltration lubrication；As plunger 4 moves, the fluid stored in pin hole 28 enters the cooperation of plunger 4 and cylinder body 1
Form oil film in gap, can not only lubricate 4 side wall of plunger, but can block air by the fit clearance of cylinder body 1 and plunger 4 into
Enter to close working chamber.
Hole stepped hole a2 is left when plunger 4 does rollback and moves to arch gap chamber 30, then inlet port is closed, with plunger
4 reciprocating motion, stepped hole a2 repeat oil suction-closing cycle, are achieved that 6 outer circle of plunger pin, the lubrication of 4 outer round surface of plunger
It is acted on the oil film seal of 1 faying face of plunger 4 and cylinder body.
The present apparatus is compound to complete the automatic repairing of closing working chamber and plunger in each reciprocatory movement of plunger 4
The oil film seal function of 1 faying face of lubrication and plunger 4 and cylinder body of 4 outer round surface of 6 periphery of pin and plunger.
Control the aperture of circular hole F35-2 in damper 35, form throttling choked flow appropriate effect, control oil suction plane 24 and
1 inner surface of cylinder body forms the thickness of arch gap chamber 30, and so that arch is obtained 30 inner fluid of gap chamber has enough viscosity resistances, energy
It enough effectively prevent the fluid in hose 11 because of dead weight reflux oil storage pool, causes air to enter oil-supplementing system, subsequently into closing work
Make chamber, quantitative 8 working efficiency of diaphragm pump head is caused to reduce or fail.
Hose 11 is designed as transparence, can intuitively observe repairing and intermittent oilling effect and quantitative diaphragm pump head 8
Whether work is normal.
