Description
Technical field
The invention belongs to agriculture and forestry machinery, engineering machinery walking pump technical fields, are related to a kind of adjustable multi-joint change of flow
Measure hydraulic pump.
Background technology
The present invention designs a kind of adjustable multi-joint volume adjustable hydraulic pump of flow, passes through this various flow rate mode that can adjust
Volume adjustable hydraulic pump to realize the reasonably optimizing of power, economizes on resources, and reduces oil consumption.
Invention content
The purpose of the present invention is being directed to existing technology, there are the above problems, it is proposed that a kind of to realize the reasonable excellent of power
Change, economize on resources, reduce the adjustable multi-joint volume adjustable hydraulic pump of flow of oil consumption.
The purpose of the present invention can be realized by following technical proposal：A kind of adjustable multi-joint volume adjustable hydraulic pump of flow, packet
The pump housing is included, two for being provided with back to and being dislocatedly distributed on the pump housing wave handle, and the handle that waves is stretched out outside the pump housing, and two are waved
Handle divides row pump housing both sides, the handle position of waving for the adjustable rocked position of flow, two wave handle can be individually
Control, can also control two and wave handle, and realize the control mode that various flow rate is combined simultaneously.
As a further improvement on the present invention, four symmetrical safety overflow valves are additionally provided on the pump housing.
As the further improvement of the present invention, the safety overflow valve includes the valve body and spool that are tightly connected, described
Safety overflow valve is unadjustable valve.
Based on above-mentioned technical proposal, the embodiment of the present invention can at least generate following technique effect：This flow is adjustable more
It is reasonable in design to join volume adjustable hydraulic pump, since pump has the adjustable rocked position of discharge capacity at two, is set in each rocked position
Be equipped with and wave handle, the reasonably optimizing of power can be realized by installing the control modes such as handle additional, in the pump, by two wave shake
Put and lengthened at handle, be allowed to reach except housing, can be controlled using handle, single can respectively be controlled, can also two it is same
When control, can both reach the control mode that a variety of discharge capacities are combined, reach energy-saving and emission-reduction, reduce oil consumption function, Duo Zhongliu
Adjusting control is measured, damage of the high pressure to whole pump is prevented, improves the service life of whole pump；At the same time, there are four safety overflows
Valve protects entire hydraulic pump at any time, to prevent hyperpressure and compression shock from being damaged caused by whole pump
Description of the drawings
The specific embodiment of the present invention is described in further detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is the structure diagram of a preferred embodiment of the present invention.
Fig. 2 is the partial structural diagram of a preferred embodiment of the present invention.
Fig. 3 is the structure diagram of safety overflow valve in a preferred embodiment of the present invention.
In figure, 10, the pump housing；20th, handle is waved；30th, safety overflow valve；31st, valve body；32nd, spool.
Specific embodiment
The following is specific embodiments of the present invention and with reference to attached drawing, technical scheme of the present invention is further described,
But the present invention is not limited to these embodiments.
Technical solution provided by the invention is illustrated in more detail with reference to Fig. 1 to Fig. 3.
As shown in Figure 1 to Figure 3, the adjustable multi-joint volume adjustable hydraulic pump of this flow includes the pump housing 10, is provided on the pump housing 10
Back to and be dislocatedly distributed two wave handle 20, the handle 20 that waves is stretched out outside the pump housing 10, and two are waved handle 20 and divide the row pump housing 10
Both sides, for the adjustable rocked position of flow, two are waved handle 20 and can individually controlled for 20 position of handle of waving,
Two can be controlled simultaneously and waves handle 20, and realize the control mode that various flow rate is combined.
The present invention protects a kind of adjustable multi-joint volume adjustable hydraulic pump of flow, and since pump has at two, discharge capacity is adjustable to wave position
It puts, therefore is provided in each rocked position and waves handle 20, the reasonably optimizing of power can be realized by installing the control modes such as handle additional,
In the pump, by two wave wave and lengthened at handle 20, be allowed to reach except housing, can be controlled using handle, can be with
It is single to control respectively, can also two control simultaneously, can both reach the control mode that a variety of discharge capacities are combined, reach energy saving and subtract
Row, the function of reducing oil consumption, various flow rate adjusting control prevent damage of the high pressure to whole pump, improve the service life of whole pump.
At the same time, entire hydraulic pump is protected at any time there are four safety overflow valve 30, to prevent hyperpressure and pressure
Impact damage caused by whole pump, i.e., be additionally provided with four symmetrical safety overflow valves 30 on the pump housing 10.
Further, safety overflow valve 30 includes the valve body 31 being tightly connected and spool 32, the safety overflow valve 30 are
Unadjustable valve.Various flow rate is adjustable, reduces energy consumption, provides reliable protection for whole pump to improve the service life of whole pump.
To make 30 good seal performance of safety overflow valve, valve body 31 and the concentricity and roughness of 32 band in sealing contact of spool are equal
Stringent control.And this valve is unadjustable valve, pressure is with regard to unadjustable after the completion of assembling.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
