Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
The utility model provides a kind of drive unit of slurry pump; It comprises an oil hydraulic pump and at least two oil hydraulic motors that are connected with this oil hydraulic pump, is provided with the COMM communication that each oil hydraulic motor serial or parallel connection of may command switches between each said oil hydraulic motor and the said oil hydraulic pump.In the utility model; But utilize many hydraulic pressure driven slurry pump of serial or parallel connection each other; High speed rotating when when each oil hydraulic motor series connection, utilizing series connection drives slurry pump and obtains bigger discharge capacity, and the low speed rotation when when each oil hydraulic motor parallel connection, utilizing parallel connection reduces the mud pump delivery, therefore; Utilize the oil hydraulic motor that said structure is simple, cost is low can make slurry pump obtain the displacement variation scope of broad, thereby adapt to the job requirement under the different operating modes.
Below in conjunction with accompanying drawing the utility model embodiment's concrete realization is further detailed.
With reference to Fig. 1, the slurry pump 100 that provides for the utility model and the schematic representation that is connected of its drive unit 200.Said drive unit 200; Comprise at least two oil hydraulic motors 210 (oil hydraulic motor 210 is two in the present embodiment) and an oil hydraulic pump 220; The output shaft of each said oil hydraulic motor 210 is connected with the pump shaft 110 of slurry pump 100 through chain-wheel mechanism 230 respectively; Each said oil hydraulic motor 210 all has oil circuit 211, and each oil circuit 211 is connected with oil hydraulic pump 220 respectively, also connects the COMM communication 240 of serial or parallel connection between each oil circuit of a may command between each oil circuit 211.
Particularly, in the present embodiment, COMM communication 240 is a hydraulicdirectional control valve.This hydraulicdirectional control valve is a kind of common control valve in the market; Thereby its principle is through changing the direction that valve element position changes oil flow; When establishing a hydraulicdirectional control valve 240 between two oil circuits 211 of two oil hydraulic motors 210; The oil that flows out through oil hydraulic pump 220 can get in two oil hydraulic motors 210 through the form of hydraulicdirectional control valve 240 with serial or parallel connection, thereby realizes two serial or parallel connections between the oil hydraulic motor 210.Adopt this hydraulicdirectional control valve, interchangeability is good, and use and maintain and replace are all more convenient.Need to prove that the COMM communication here is not limited to above-mentioned hydraulicdirectional control valve, it also can be replaced by other switching valves.
Further,, also be connected with throttle valve 250 between two oil circuits 211 of two oil hydraulic motors 210, connect an overflow pipe 260 on the throttle valve 250 as an optimisation technique scheme of the utility model.When two oil circuits 211 of two oil hydraulic motors 210 were realized series connection through hydraulicdirectional control valve control, two oil hydraulic motors 210 were through the oil of same traffic, and when parallel connection; In oily average mark Zhi Liuxiang two oil circuits 211 by oil hydraulic pump 220 outflows; Like this, two oil hydraulic motors 210 are when series and parallel, and the oil mass of flowing through differs one times; So under two kinds of patterns of series and parallel, the driving rotating speed of slurry pump is a high speed and a low speed two step velocitys.In the present embodiment; Can be implemented in the middle of the series and parallel two-stage drive speed through throttle valve 250 and overflow pipe 260; Can also adjust motor rotary speed continuously, make the actuating speed of slurry pump up to zero rotating speed, can regulate actuating speed to the middling speed of parallel connection continuously from the maximum speed of series connection.
