A kind of dynamical system of rotary drilling rig comprises two cover equal-wattages and can be separately or the power set of power are provided for rotary drilling rig jointly, and every cover power set are respectively by main pump output, interflow same main valve extremely before the valve, thus realize each action.
Following further improvement of the utility model:
Described wherein cover power set comprise the first motor, the front portion of described the first motor connects the first noise damper by one section bellows, the centre position of described motor is connected with the first air filter by an air inlet pipe, and the rear portion of the first motor is connected with the first radiator by an output shaft.
Further improve:
Described another set of power set comprise the second motor, the front portion of described the second motor connects the second noise damper by one section bellows, the centre position of described the second motor is connected with the second air filter by an air inlet pipe, and the rear portion of the second motor is connected with the second radiator by an output shaft.
Further improve:
Described the first motor links to each other with the first main pump by shaft coupling, and the second motor links to each other with the second main pump by shaft coupling, and then respectively by fluid pressure line and hydraulically-controlled one-way valve, the interflow enters main valve, thereby realizes each action.
The utility model adopts technique scheme, and the motor of two equal-wattages that work alone is as power resources, and each motor is equipped with a main pump, and each action of rotary drilling rig is realized to same main valve in the interflow before each main pump valve; Can regulate two motors according to the situation of operating mode and work independently or associated working, and can use the product of ripe resource, delivery cycle is short, and purchase cost is lower, thereby has effectively saved the energy, has reduced cost.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Among the figure: 1-the first motor; 2-the first noise damper; 3-the first air filter; 4-the first radiator; 5-the second air filter; 6-the second radiator; 7-the second motor; 8-the second noise damper; 9-the first main pump; 10-the second main pump; The 11-main valve.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of dynamical system of rotary drilling rig, this dynamical system comprises two cover equal-wattages and can be separately or the common power set that power is provided for rotary drilling rig, every cover power set by main pump output, collaborate to same main valve before the valve, thereby realize each action respectively.
Wherein cover in the described two cover power set comprises the first motor 1, the front portion of described the first motor 1 connects the first noise damper 2 by one section bellows, the centre position of described the first motor 1 is connected with the first radiator 4 by the rear portion that an air inlet pipe is connected with the first air filter 3, the first motors 1 by output shaft.
Another set of power set comprise the second motor 7, the front portion of described the second motor 7 connects the second noise damper 8 by one section bellows, the centre position of described the second motor 7 is connected with the second radiator 6 by the rear portion that an air inlet pipe is connected with the second air filter 5, the second motors 7 by an output shaft.
Described the first motor 1 links to each other with the first main pump 9 by shaft coupling, the second motor 7 links to each other with the second main pump 10 by shaft coupling, the first main pump 9, the second main pump 10 are respectively by fluid pressure line and hydraulically-controlled one-way valve, the interflow enters main valve 11, main valve 11 links to each other with the dynamical element of rotary drilling rig, realizes each action of rotary drilling rig.
The technical scheme that the utility model provides, rotary drilling rig uses the first motor 1 (comings QSB6.7, rated power is 164kW) and the second motor 7 (comings QSB6.7, rated power is 164kW) two low-powered engines that power is identical provide power resources, the first motor 1 and the second motor 7 have independently cooling system, air filter alone and noise damper separately, and each motor can work independently.
