Description

The rotating mechanism of long core holding unit

Technical field

The utility model relates to a kind of rotating mechanism of long core holding unit, belongs to the chemical industry Instrument technology field.

Background technology

Long core holding unit is mainly used in the various simulation tests of hydrocarbon zone rock core, like water filling, acidifying, pressure break, infiltration system, mensuration etc.

Existing long core holding unit exists following weak point:

1, during the gas displacement, because gas, liquid density are different, in long rock core displacement process, have liquid-gas interface in the rock core, gas is last, and liquid is descending, 50% rock core volume displacement less than, can not reach the gas drive experiment purpose;

2, manually simulate core axis to 360 ° of forward and reverse rotations, can not accurately control rotational angle and rotate the inclination angle with control in real time.And can't manually rotate inconvenience for large-scale long core holding unit.

Summary of the invention

The purpose of the utility model is the weak point that overcomes prior art, and a kind of rotating mechanism of long core holding unit is provided.

The rotating mechanism of the long core holding unit of the utility model comprises the sheath that is used to encase rotating mechanism, is fixed on the external fixation plate on the long core holding unit; Be fixed on bearing bridge and bearing and cap on the external fixation plate, be fixed on the bearing on bearing bridge and bearing and the cap, be fixed on the tooth rest on the long core holding unit; Be fixed on the gear wheel on the tooth rest, be installed in the connecting key on the gear wheel, be fixed on the pinion wheel on the external fixation plate; The worm gear case output shaft that links to each other with pinion wheel is installed in motor and worm gear reducer on the external fixation plate, is located at the motor output shaft gear on the motor; Be located at the worm gear case output shaft gear on the worm gear reducer

The long core holding unit rotating mechanism of the utility model has following technique effect:

The clamper cylindrical shell is under motor, reducer casing, gear wheel, pinion wheel and interlock circuit control; Can realize rock core 360 ° of forward and reverse rotations vertically; Can guarantee that through regulating rotating speed rock core inside is in the process of gas displacement; Gas-liquid can well be distributed in each position of rock core, does not have liquid-gas interface; It is the same to be similar to the principle that increase is stirred to potpourri, makes gas-liquid mixed even, and 100% rock core position can be arrived by displacement in guaranteeing to test; The radially 360 ° of positive and negative rotations of long core holding unit; Axial 0～90 ° adjustable.
