Description
Technical field
The present invention relates to a kind of rotor with slow-speed of revolution rotation can be to the blade hydraulic pump of liquid pressing.
Background technique
Oil hydraulic pump is used for liquid is pressurizeed, the rear liquid with certain pressure of exporting can provide a power by pressurizeing, namely utilizing the interior low pressure liquid of inflow pump to become highly pressurised liquid after the pump pressurization is exported, characteristic is applicable on the various machinery that hydraulic pressure demand arranged whereby, such as: the bulldozer of plastic forming or general building equipment or excavator etc.
As shown in Fig. 6 to 8, oil hydraulic pump for prior art, it includes a casing ontology 10, its inside is the pressurized chamber 11 of a tool hollow shape, be provided with the entrance 12 and outlet 13 that are communicated with pressurized chamber 11 on casing ontology 10, the internal ring wall face of this pressurized chamber 11 forms a non-positive circular design, run through on this casing ontology 10 and be provided with a live axle 14 that wears 11 inside to this pressurized chamber, this live axle 14 is provided with a rotor 50 that is positioned at 11 inside, pressurized chamber, and this live axle 14 is rotating being hubbed on casing ontology 10;
this rotor 50 is a cylindrical body, its center is provided with an axis hole 51, this axis hole 51 is interconnected and fixed with an end of live axle 14, the other end of this live axle 14 is driven rotation by dynamic power machine, this dynamic power machine can be the motor of various types, be concaved with a plurality of blade grooves 52 on the outer shroud wall of rotor 50, be provided with the scraping blade 53 that can freely move radially in this blade groove 52, this scraping blade 53 slidably contacts with the internal ring wall face formation of pressurized chamber 11 with the end 531 that compresses that is positioned at rotor 50 outside one ends, be subject to that dynamic power machine drives and during High Rotation Speed at live axle 14 whereby, each scraping blade 53 with its centrifugal force towards the outer side shifting of rotor 50 and the internal ring wall face that abuts in pressurized chamber 11 to compress end 531, pass towards outlet 13 to reach the liquid that to be flowed into by entrance 12, and reach to liquid pressurizeed after by the outlet 13 output.
the oil hydraulic pump of prior art is in order to make liquid have certain hydraulic pressure when exporting by exporting, must make under the rotation of rotor with higher rotation speed, by set each scraping blade of rotor after centrifugal action, move respectively and compress with certain pressure the internal ring wall face that abuts in the pressurized chamber towards the outside, so begin to reach and to be pressurizeed by the hydraulic pressure of entrance input afterwards by outlet output, prior art is in order to obtain to have the centrifugal force of pressurization, therefore the rotating speed of rotor is necessary for high rotating speed, for example: rotating speed is 600RPM to 800RPM, even rotating speed must be up to 10000RPM, beginning to form required centrifugal force pressurizes to liquid to reach,
Utilize the oil hydraulic pump of blade type due to prior art, under high-revolving rotation like this to liquid pressing, to make the interelement abrasion of each unit cause more greatly the loss of each parts, moreover utilize high rotating speed to drive the rotor rotation and also must expend the more shortcomings such as power source.
Summary of the invention
Because aforementioned prior art must begin to reach to liquid pressing under high rotating speed in use, and then cause parts easily to wear away to damage and cause the shortcoming such as expending of the energy, thereby the invention provides a kind of blade hydraulic pump, can be that the rotor that the slow-speed of revolution (for example: rotating speed is about 5RPM to 1000RPM) is rotated still can be to liquid pressing to required pressure at rotating speed.
For this reason, the present invention proposes a kind of blade hydraulic pump, and it has a casing ontology, a live axle, a rotor and a plurality of scraping blade; This casing ontology is a hollow article, be formed with a pressurized chamber in inside, separately be provided with an entrance, outlet and a slotted hole on casing ontology, one end of this entrance, this outlet and this slotted hole communicates with this pressurized chamber, the exterior of the other end and casing ontology, this live axle is a long shaft rod, and it wears and is positioned at this slotted hole; This rotor, it is arranged in the pressurized chamber, and an end of the center of rotor and this live axle interconnects, and is concaved with a plurality of blade grooves on the outer shroud wall of rotor; These a plurality of scraping blades, relatively be provided with a scraping blade in this blade groove, one distal process of this scraping blade is stretched and is formed one in rotor exterior and its end and compress end, its the other end is provided with at least one containing groove, be provided with an elastic element in this containing groove, an end of this elastic element is butted on the groove bottom of containing groove, and the other end is butted on the blade groove groove bottom of rotor, this elastic element ejection scraping blade compresses the internal face that end is butted on the pressurized chamber.
Described blade hydraulic pump, wherein this blade groove is provided with locating column in groove bottom, and this locating column is positioned at the containing groove position of set this scraping blade relatively, and an end of this spring is set on this relative locating column.
Described blade hydraulic pump wherein is provided with two containing grooves on each scraping blade.
