The utility model discloses rational in infrastructure, the working property is good. Adopt the hydraulic motor more than 2 or 2, when power device output flow rate, a pressure timing, when needing to export high -speed low moment of torsion, two hydraulic motor one -tenth is established ties and is imported, when the high moment of torsion of need output low -speed, two hydraulic motor switch into the parallel in.
Description
Technical field
The series parallel connection that the utility model relates to a kind of hydraulic pressure water tap switches output mechanism.
Background technique
Hydraulic pressure water tap is inputted by oil hydraulic motor, and through gear transmission, to swivel stem output speed and moment of torsion, swivel stem is connected with well workover drilling tool, realizes workover eration.The needs of output speed and moment of torsion needed for hydraulic pressure swivel stem, namely export at high speed low torque or low speed and large torque two kinds and need, but existing output mechanism can not realize above-mentioned functions.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, and the series parallel connection of the hydraulic pressure water tap of favorable working performance switches output mechanism.
Technical solution of the present utility model is:
The series parallel connection of hydraulic pressure water tap switches an output mechanism, and it is characterized in that: comprise multiple hydraulic motor, arrange switching valve between hydraulic motor, the control mouth of switching valve is connected with solenoid valve through reduction valve; By the switching of switching valve, the serial or parallel connection realizing multiple hydraulic motor exports.
Hydraulic motor has two.
The utility model is rational in infrastructure, favorable working performance.Adopt the oil hydraulic motor of more than 2 or 2, when power plant output flow, pressure one timing, when need export high speed low torque, two oil hydraulic motors become series connection input; When exporting low speed and large torque, two oil hydraulic motors switch to input in parallel.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The series parallel connection of hydraulic pressure water tap switches an output mechanism, comprises the first hydraulic motor 1, second oil hydraulic motor 3, arranges switching valve 2 between first, second hydraulic motor, and the control mouth of switching valve is connected with solenoid valve 4 through control pipeline 6, reduction valve 5; By the switching of switching valve, the serial or parallel connection realizing first, second hydraulic motor exports.
Working principle:
One, series operation state: working position when solenoid valve 4 is in off-position is for 1.; Control mouth Ps to disconnect, the control mouth of switching valve 2 is through controlling pipeline 6, reduction valve 5, solenoid valve 4 and oil return inlet T s conducting, switching valve 2 resets, 3. its working position is, the hydraulic fluid port e of switching valve 2 and hydraulic fluid port d conducting, hydraulic fluid port c and hydraulic fluid port f disconnects, and main hydraulic power is inputted by hydraulic fluid port A, through A1 → the first hydraulic motor → B1 → switching valve (e → d) → A2 → the second hydraulic motor → B2, exported by B hydraulic fluid port; Or main hydraulic power is inputted by hydraulic fluid port B, through B2 → the second hydraulic motor → A2 → switching valve (d → e) → B1 → the first hydraulic motor → A1, exported by A hydraulic fluid port; Realize the forward or reverse of series connection motor.
Two, parallel operation state: working position when solenoid valve 4 is in off-position is for 2.; Control mouth Ps to connect, controlling oil makes switching valve 2 switch to position 4. through solenoid valve 4, reduction valve 5, control pipeline 6, the hydraulic fluid port e of switching valve 2 and hydraulic fluid port f conducting, hydraulic fluid port c and hydraulic fluid port d conducting, main hydraulic power inputs a point two-way by hydraulic fluid port A: a road, through A1 → the first hydraulic motor → B1 → switching valve (e → f), is exported by B hydraulic fluid port; Another road, through switching valve (c → d) → A2 → the second hydraulic motor → B2, is incorporated to B hydraulic fluid port and exports.Or inputting a point two-way by hydraulic fluid port B: a road, through B2 → the second hydraulic motor → A2 → switching valve (d → c), is exported by A hydraulic fluid port; Another road, through switching valve (f → e) → B1 → the first hydraulic motor → A1, is incorporated to A hydraulic fluid port and exports; Realize the forward or reverse of motor in parallel.
Therefore, when determining hydraulic power parameter (output flow and pressure), when switching to the series connection of first, second oil hydraulic motor, being equivalent to single hydraulic motor and exporting, is high rpm low torque output state; When switching to first, second hydraulic motor and being in parallel, being equivalent to two hydraulic motors and exporting simultaneously, is slow-speed of revolution height moment of torsion output state.
Faucet body is suspended in well workover derrick by drop handle by hydraulic pressure water tap, switching valve assembly, first, second hydraulic motor are all installed on faucet body, and power and rotating speed are passed to center tube and exports by the gear transmission in first, second hydraulic motor and water tap; Hydraulic fluid port A, B, O on hydraulic power access switching valve assembly; The series parallel connection of two oil hydraulic motors switches, and realizes the rotating speed of center tube, moment of torsion height exports.
