Abstract
A kind of new hydraulic pump of the present invention is often rotated to an angle using a pair of mutual " conjugation spouse " connecting rod slider components, bent axle is installed on the same crank throw of bent axle, that is, has plunger to reach suction, the extreme position of discharge opeing, so as to realize hydraulic pump while suction, discharge opeing work.Due to plunger no-idle running, therefore under the requirement of same traffic, nominal pressure and rotating speed, it is greatly improved operating efficiency.A kind of novel hydraulic pump plunger of the present invention is using being arranged symmetrically, and bent axle stress is more reasonable, so as to extend its service life；Axial dimension is small, compact conformation, while having reduced the difficulty of processing and production cost into some critical components；Also have stability of flow, pressure oscillation small and the low advantage of noise level.
Description
Technical field
The present invention relates to a kind of hydraulic pump, the career field of the existing emulsion pump of in the market is applicable not only to, also be can use
In other hydraulic systems, and with compact conformation, huge discharge, energy-conservation, it is efficient the features such as.
Background technology
At present, the existing emulsion pump of in the market drives unilateral connecting rod slider component to make reciprocating linear fortune by crank throw
It is dynamic, suction, the discharge opeing work of emulsion pump are realized, its operation characteristic is interval, and it is low to run unstable, efficiency.
The content of the invention
In order to overcome existing emulsion pump interval, run the low present situation of unstable, efficiency, the present invention is a kind of hydraulic pressure
Pump, can not only realize continuous suction, discharge opeing work, and make the uniform force of bent axle, and compact conformation is reasonable.
The present invention solves the technical scheme that is used of above-mentioned technical problem：Face-off formula structure is taken, the hydraulic pump is by machine
Tool running part, connecting rod slider component, cylinder sleeve component, valve component, the storage composition such as oil pipe component and shunt tube assemblies.Its feature
" conjugation spouse " a pair of links slide block assembly on each crank throw of bent axle, wherein every group of connecting rod slider component, cylinder sleeve component,
Valve component, the storage structure such as oil pipe component and shunt tube assemblies are identical.The reciprocal of plunger is converted into by the rotary motion of bent axle
Linear motion, realizes continuous suction, discharge opeing work.
A kind of outstanding advantages of hydraulic pump of invention：
1st, due to plunger no-idle running, therefore under equal nominal flow rate, nominal pressure and same rotational speed, a kind of hydraulic pump
Realize that the emulsion pump of the other manner work of suction, discharge opeing, therefore efficiency more in the market simultaneously is greatly improved；
2nd,, can be big under conditions of identical nominal flow rate, nominal pressure and rotating speed compared with hydraulic pump in the market
The big overall dimensions for reducing emulsion pump, structure is compacter, greatly reduces Master Cost and cost, and reduce some key components
Difficulty of processing etc.；
3rd, plunger of the invention is arranged symmetrically on crankshaft crank, and bent axle stress is more reasonable, and operation is more steady, can extend song
Axle service life.Under conditions of identical nominal flow rate, nominal pressure and rotating speed compared with the emulsion pump that other manner works,
Axial dimension reduces a lot, and its flow, pressure fluctuation are small, steady during operation, and noise is low.
Brief description of the drawings
Accompanying drawing provides a kind of structural representation of hydraulic pump of the present invention：Fig. 1 is that a kind of hydraulic pump axis one of the invention is bent
The double plunger structure principle chart turned.Fig. 2 is to install a pair that " conjugation is matched somebody with somebody in a kind of hydraulic pump of the invention on the same crank throw of bent axle
Connecting rod slider component planes layout drawing occasionally ".
The label declaration of parts in schematic diagram：1 stores the oil cooling service pipe component of 2 shunt tube assemblies of oil pipe component, 3 bent axle 4
The plungers of 5 valve component, 6 cylinder sleeve component, 7 casing, 8 connecting rod slider component a, 9 connecting rod slider component b 10.
Embodiment
With reference to Figure of description, suction, discharge opeing work while work system can be completed to a kind of hydraulic pump of the invention
Make taken technical scheme to be described further：
By taking Fig. 1 crankshaft crank as an example, when bent axle is rotated in an anti-clockwise direction, crank throw center turns left, and promotes 8 connecting rods
Slide block assembly a (connecting rod, sliding block, plunger) is moved to left, in the plunger ante-chamber in this connecting rod slider component a liquid by the left side 5 valves
Body component discharge opeing；When the crank throw center is turned left, while also drive 9 connecting rod slider component b to be moved to the left, this connecting rod slider component
In plunger ante-chamber in b liquid by the right 5 valve component imbibitions.
8 connecting rod slider component a are arranged on the axle journal of bent axle in Fig. 1 combinations Fig. 2 crankshaft crank, the present invention, 9 connecting rods
Slide block assembly b is arc structure close to the stub end of bent axle, and 9 connecting rod slider component b are installed on 8 connecting rod slider component a periphery；
And hydraulic pump takes symmetrical structure；8 connecting rod slider component a are socketed on axle journal close to one end of bent axle；9 connecting rods
Slide block assembly b exceedes the axle center of axle journal close to the end of the arc structure of bent axle.
Above is so that the crank throw of bent axle one completes suction, the specific implementation structural principle of discharge opeing work as an example, for whole bent axle,
It is made up of, therefore is rotated with bent axle per certain angle multiple crank throws, just has ram travel to reach capacity position, that is, complete emulsification
Liquid pump is inhaled simultaneously, discharge opeing work.In the course of the work, the amount of force born by a pair of plungers, direction are different for bent axle,
Partial pressure can be achieved to offset, so as to improve the force-bearing situation of bent axle.Each plunger no-idle running in the course of the work simultaneously, because
This is greatly improved operating efficiency under same traffic, nominal pressure and rotating speed.
