Abstract
The invention discloses an energy-saving pump body, and relates to a hydraulic pump. The energy-saving pump body comprises an oil inlet (1), an oil outlet (2) and a center shaft (3), and the oil inlet (1) and the oil outlet (2) are formed in the two sides of the center shaft (3) respectively. The energy-saving pump body is characterized in that the oil inlet (1) is connected with an oil inlet channel (12), the two sides of the oil inlet channel (12) are respectively provided with an oil inlet groove (11), the oil inlet (1) and the oil outlet (2) are respectively provided with a flow monitoring device, each flow monitoring device is provided with a PLC, and the oil inlet channel (12) is provided with a temperature control switch. The energy-saving pump body is small in size, large in oil conveying quantity, and high in volume efficiency.
Description
Technical field
What the present invention relates to is a kind of oil hydraulic pump, is specifically related to a kind of energy-saving pump housing.
Background technique
Interior engagement circular arc-general cycloid gear pump (also claiming rotor engine oil pump) is compared with outer gearing involute gear pump, the distinguishing feature such as have compact structure, volume is little, and per unit volume discharge capacity is large, and part is few, with low cost.Interior engagement circular arc-general cycloid gear pump has now been widely used as " heart " of internal-combustion engine, vehicle lubricating system, and its performance quality directly affects reliability and the durability of internal-combustion engine.Therefore interior engagement circular arc-general cycloid gear pump that, design performance is good, efficiency is high just seems extremely important.
But traditional general external gear pump is radially oil-feed, volumetric efficiency is lower, although the volumetric efficiency of interior engagement circular arc-general cycloid gear pump is high, but the design of its oil groove is unreasonable, fluid is filled bad, volumetric efficiency can be on a declining curve with revolution speed rising, also can produce cavitation phenomenon.
In sum, all there is defect in these two kinds of gear pumps, need to take effective measures and improve its volumetric efficiency.
Summary of the invention
For the deficiency existing in prior art, the present invention seeks to be to provide the energy-saving pump housing, its volume is little, and oil transportation amount is large, and volumetric efficiency is high.
To achieve these goals, the present invention realizes by the following technical solutions: it comprises filler opening, oil outlet and central shaft, central shaft both sides are respectively arranged with filler opening and oil outlet, and described filler opening is connected with oil inlet passage, and oil inlet passage both sides are provided with oil-feed tank; Described oil outlet is connected with oil discharge passage, oil discharge passage both sides are provided with out oil groove, on described filler opening and oil outlet, be equipped with flow monitoring device, described flow monitoring device is provided with PLC controller, on described filler opening and oil outlet, be all movably equipped with filter screen, described filter screen is detachable, and described oil inlet passage is provided with temperature detect switch (TDS).
As preferably, described central shaft is two-way oil-feed axle.
As preferably, described oil inlet passage consists of metal layer, zone of heating, thermal-protective coating and skin.
As preferably, described metal internal layer is tungsten alloy.
As preferably, in described zone of heating, be provided with quartz tube.
As preferably, described thermal-protective coating is rock wool layer.
As preferably, described skin is silica
Oil-feed tank of the present invention has strengthened, and has also extended the oil-filled time, has improved volumetric efficiency, and fuel delivery increases.Fuel-displaced groove shape has also extended the oil extraction time, more smooth and easy during oil extraction, has reduced the air horsepower of pump.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the present invention in detail;
Fig. 1 is structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
With reference to Fig. 1, this embodiment is by the following technical solutions: it comprises filler opening 1, oil outlet 2 and central shaft 3, central shaft 3 both sides are respectively arranged with filler opening 1 and oil outlet 2, and described filler opening 1 is connected with oil inlet passage 12, and oil inlet passage 12 both sides are provided with oil-feed tank 11; Described oil outlet 2 is connected with oil discharge passage 22, oil discharge passage 22 both sides are provided with out oil groove 21, on described filler opening 1 and oil outlet 2, be equipped with flow monitoring device, described flow monitoring device is provided with PLC controller, on described filler opening 1 and oil outlet 2, be all movably equipped with filter screen, described filter screen is detachable, and described oil inlet passage 2 is provided with temperature detect switch (TDS).
It should be noted that described central shaft 3 is for two-way oil-feed axle; From the oil-feed simultaneously of gear both ends of the surface.
It should be noted that described oil inlet passage 2 consists of metal layer, zone of heating, thermal-protective coating and skin.
It should be noted that described metal internal layer is tungsten alloy.
It should be noted that in described zone of heating and be provided with quartz tube.
It should be noted that described thermal-protective coating is rock wool layer.
It should be noted that described skin is silica
This embodiment makes one side axial fuel inlet into bi-directional axial oil-feed, owing to having increased oil-feed point, has relatively extended the time of fluid filling between cog, has improved fluid filling capacity.
The oil-feed tank of this embodiment has strengthened, and has also extended the oil-filled time, has improved volumetric efficiency, and fuel delivery increases.Fuel-displaced groove shape has also extended the oil extraction time, more smooth and easy during oil extraction, has reduced the air horsepower of pump.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
