The system is simple and reliable and has strong practicability.
Description
Technical field
The utility model relates to a kind of hydraulic-pressure logging truck Ultra-Low Speed and controls system.
Background technology
In the oil test jobs, some special test events are arranged, the linear velocity that requires cable is very low just to satisfy the demands, the minimum 50-60m/h of existing hydraulic-pressure logging truck cable speed, special item requires logging cable below 30m/h, therefore is necessary to improve.
The utility model content
The technical problem that the utility model solves: provide in a kind of oil test jobs special test event to the hydraulic-pressure logging truck Ultra-Low Speed control system of equipment specific (special) requirements.
The technical scheme that the utility model adopts: hydraulic-pressure logging truck Ultra-Low Speed control system; Comprise hydraulic pump, hydraulic motor and reductor; An input of an output termination hydraulic motor of said hydraulic pump; Said hydraulic motor output termination reductor input, said reductor output termination well logging cylinder, an input of another output termination low speed control valve of said hydraulic pump; Said another input of low speed control valve output termination hydraulic motor, another input of said low speed control valve connects the conversion switch.
Further, said hydraulic pump is connected to joystick.
Wherein, said reductor is a planetary reducer.
The utility model compared with prior art system is simple and reliable, and is practical.
Description of drawings
Fig. 1 is the utility model theory diagram.
The specific embodiment
A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1.
Hydraulic-pressure logging truck Ultra-Low Speed control system; Comprise hydraulic pump, hydraulic motor and planetary reducer; An input of an output termination hydraulic motor of said hydraulic pump, said hydraulic motor output termination planetary reducer input, said planetary reducer output termination well logging cylinder; An input of another output termination low speed control valve of said hydraulic pump; Said another input of low speed control valve output termination hydraulic motor, another input of said low speed control valve connects the conversion switch, and hydraulic pump is connected to joystick.Use native system smoothly adjustable-speed on a large scale, make the linear velocity of cable in the well logging process minimum stable, can satisfy the special test of well logging project to 25m/h.
Operating principle: when normal operating conditions, hydraulic pump directly drives hydraulic motor, and fluid motor-driven planetary reducer, planetary reducer drive the well logging cylinder with normal speed work, and the linear velocity of logging cable is at 100-600m/h at this moment.When special test event in the oil test jobs proposes specific (special) requirements to equipment, as when requiring logging cable linear velocity 30m/h following, open the low speed control valve this moment; Under the changeover switch effect; Hydraulic pump drives hydraulic motor through low speed valve, and hydraulic motor drives planetary reducer more then, and planetary reducer drives the well logging cylinder again with very low speed operation; Minimum speed can reach 25m/h, satisfies the demand of special test event fully.
The foregoing description, just the preferred embodiment of the utility model is not to be used for limiting the utility model practical range, so all equivalences of being done with the said content of the utility model claim change, all should be included within the utility model claim scope.
