Abstract

The invention provides a novel hydraulic pump. The hydraulic pump is characterized in that a pair of connecting rod sliding block components which are conjugate spouses is arranged on a same crank throw of a crank shaft; the crank shaft rotates at a certain angle, a plunger piston reaches limit positions of liquid absorbing and drainage, thereby realizing liquid absorbing and drainage work of a hydraulic pump synchronously. As the plunger piston has no idle stroke, the working efficiency can be greatly improved under the condition that the flow, nominal pressure and rotary speed are the same. According to the hydraulic pump provided by the invention, the plunger pistons are arranged symmetrically, thus, the crank shaft can be stressed more reasonably, and the service life of the crank shaft can be prolonged; the axial dimension is small, the structure is compact, and meanwhile, the processing difficulty and production cost of some key components are reduced; and moreover, the hydraulic pump has the advantages of stable flow, small pressure fluctuation, low noise level and the like.

Description

A kind of new hydraulic pump

Technical field

The present invention relates to a kind of new hydraulic pump, be not only applicable to the career field of existing emulsion pump on the market, also can be used for other hydraulic systems, and have compact structure, big discharge capacity, characteristics such as energy-conservation, efficient.

Background technique

At present, existing emulsion pump does reciprocating linear motion through the one-sided connecting rod slider assembly of crank throw drive on the market, realizes suction, the discharge opeing work of emulsion pump, and its roadability is intermittently, and operation is not steady, efficient is low.

Summary of the invention

For overcome existing emulsion pump intermittently, not steady, the inefficient present situation of operation, the present invention be a kind of new hydraulic pump, not only can realize continuous suction, discharge opeing work, and makes the stressed even of bent axle, compact structure is reasonable.

The present invention solves the problems of the technologies described above the technological scheme that is adopted: the formula structure of taking to stand facing each other, this oil hydraulic pump by mechanical driving part, connecting rod slider assembly, cylinder sleeve assembly, valve component, hold oil pipe assembly and shunt tube assemblies etc. and form.It is characterized in that " conjugation spouse " pair of links slide block assembly on each crank throw of bent axle, wherein every group of connecting rod slider assembly, cylinder sleeve assembly, valve component, to hold structures such as oil pipe assembly and shunt tube assemblies identical.Convert the linear reciprocating motion of plunger to through rotatablely moving of bent axle, realize inhaling continuously, discharge opeing work.

The outstanding advantage of a kind of new hydraulic pump of invention:

1, owing to the plunger no-idle running, therefore under equal nominal flow rate, nominal pressure and same rotational speed, a kind of new hydraulic pump is realized inhaling simultaneously, discharge opeing, so the emulsion pump of efficient alternate manner work more in the market improves greatly;

2, compare with oil hydraulic pump in the market; Under the condition of identical nominal flow rate, nominal pressure and rotating speed, can reduce the overall dimensions of emulsion pump greatly, structure is compact more; Significantly reduce Master Cost and cost, and reduce difficulty of processing of some key components etc.;

3, plunger of the present invention symmetric arrangement on crankshaft crank, bent axle is stressed more reasonable, moves more steadily, can prolong bent axle working life.Under the condition of identical nominal flow rate, nominal pressure and rotating speed, compare with the emulsion pump of alternate manner work, axial dimension reduces a lot, and when operation its flow, pressure pulsation is little, steady, and noise is low.

Description of drawings

It is the double-plunger structure principle chart on a kind of new hydraulic pump axis one crank throw of the present invention that accompanying drawing provides the structural representation of a kind of new hydraulic pump of the present invention: Fig. 1.Fig. 2 is the connecting rod slider assembly situation plan that a pair of " conjugation spouse " is installed on the same crank throw of bent axle in a kind of new hydraulic pump of the present invention.

The label declaration of component in the schematic representation: 1 holds oil pipe assembly 2 shunt tube assemblies 3 bent axles 4 oil cooling service pipe assemblies 5 valve components 6 cylinder sleeve assemblies 7 casings 8 connecting rod slider assembly a 9 connecting rod slider assembly b 10 plungers.

Embodiment

Below in conjunction with Figure of description, the technological scheme of inhale when can finish the work system to a kind of new hydraulic pump of the present invention, discharge opeing work being taked further specifies:

Crankshaft crank with Fig. 1 is an example; When bent axle counterclockwise rotates; The crank throw center turns left, and promotes 8 connecting rod slider assembly a (connecting rod, slide block, plunger) and moves to left, and liquid is through the 5 valve component discharge opeings on the left side in the plunger ante-chamber among this connecting rod slider assembly a; When turn left in this crank throw center, also drive 9 connecting rod slider assembly b simultaneously and be moved to the left, liquid is through the 5 valve component imbibitions on the right in the plunger ante-chamber among this connecting rod slider assembly b.

More than be with bent axle one crank throw accomplish to inhale, the practical implementation structural principle of discharge opeing work is example; For whole bent axle, constitute by a plurality of crank throws, therefore with each fixed angle of crankshaft rotating; The plunger stroke position that reaches capacity is just arranged, accomplish promptly that emulsion pump is inhaled simultaneously, discharge opeing work.Bent axle in the course of the work because amount of force that a pair of plunger bore, direction are different, but the implementation part counteracted by pressure, thereby improved the force-bearing situation of bent axle.Each plunger of while is no-idle running in the course of the work, therefore under same traffic, nominal pressure and rotating speed, can increase work efficiency greatly.

Claims

1. new hydraulic pump; Form by mechanical driving part, bent axle, connecting rod slider assembly 1, connecting rod slider assembly 2, valve component, cylinder sleeve assembly, cooling tube assembly, ram's horns etc.; Effect is to convert mechanical energy to the hydraulic pressure ability; To give operation mechanism's energizing quantity, the present invention is in line with the design concept of " few crank throw multicolumn plug ", to solve the contradiction of big discharge capacity and compact integral structure; Structurally, the main distinction with existing emulsion pump is: the same connecting rod slider assembly that drives two " conjugation spouses " simultaneously that turns of bent axle.

2. according to claims 1 described a kind of new hydraulic pump, its working principle: convert rotatablely moving of bent axle to the linear reciprocating motion of connecting rod slider assembly of " the conjugation spouse " of two groups of symmetric arrangement, suction, the discharge opeing that the realizes plunger work that moves in circles.
