Summary of the invention:

The purpose of the utility model is: a kind of motor tank tuck pump drainage liquid device is provided, prevents that when pumping liquid liquid or impurity mistake from sucking in the vacuum pump, can pressurize during discharge liquid and accelerate discharging, and can spray at a distance in tank body.

The technical solution of the utility model is: this motor tank tuck pump drainage liquid device comprises tank body, A pipe, B pipe, moisture separator, C pipe, D pipe, E pipe, four-way cock, control handle, F pipe, vacuum indicator, check valve, G pipe, vacuum pump, fixed mount, H pipe, oil separator, outside atmosphere pipe; Tank body is connected with the A pipe, and the A pipe is connected with the B pipe, and the B pipe connects moisture separator simultaneously; Moisture separator also is connected with the C pipe; C pipe, D pipe, E pipe are communicated with successively, and four-way cock connects E pipe, F pipe, oil separator and outside atmosphere pipe, and four-way cock also has control handle; Have vacuum indicator on the F pipe and be connected with check valve; Check valve also is connected with vacuum pump through the G pipe, and vacuum pump is placed on the fixed mount, and vacuum pump also is connected with oil separator through the H pipe.

The good effect of the utility model is: this motor tank tuck pump drainage liquid device can prevent when pumping liquid that liquid or impurity mistake from sucking in the vacuum pump; Prolong vacuum pump service life; When discharge liquid, can in tank body, pressurize simultaneously; Accelerate to irritate the discharge of liquid in the body, increase work efficiency, and can spray at a distance.

Description of drawings:

Fig. 1 is the plan structure scheme drawing of the utility model, and Fig. 2 is the side-looking structural representation of the utility model.
