Abstract
The utility model belongs to a gear pump for conveying liquid, in particular to a special gear pump for a PVB extruder. A drive shaft and a driven shaft installed on the sidewall of a pump body are arranged in parallel in the pump body; the drive shaft and the driven shaft are both equipped with supercharging gears meshed with each other; a liquid inlet chamber and a liquid outlet chamber are formed between the two meshed supercharging gears and the inner wall of the pump body; a feeding opening is arranged on the sidewall of the pump body in the liquid inlet chamber; a discharging opening is arranged on the sidewall of the pump body in the liquid outlet chamber; the drive shaft extends out of the pump body and is connected with a drive shaft of a power device; screw holes for connection are arranged on the sidewalls of the pump body in the feeding opening and the discharging opening both; and due to the structural characteristics, the special gear pump disclosed by the utility model has the advantages of simple structure, low cost, good sealing performance, high work efficiency, good-looking appearance and the like.
Description
Technical field
The utility model belongs to the gear pump of carrying liquid, and particularly a kind of PVB extruder is carried the dedicated gear pump of colloidal liquid.
Background technique
In the production of PVB intermediate coat, the conveying of melt be unable to do without gear pump, and general gear pump includes the pump housing, live axle, driven shaft, bearing and Sealing.The gear pump that is applied to PVB intermediate coat extruder at present have 2 cumbersome: a bit be all to be provided with seal ring; The seal ring limited service life needs often to change; On the other hand the inner chamber of the pump housing often needs lubricated; Also suitable trouble, thus have influence on the working life and the working efficiency of whole gear pump on the whole, and therefore the improvement to gear pump is necessary.
Summary of the invention
The purpose of the utility model provides a kind of novel without seal ring, the PVB extruder dedicated gear pump that also need not lubricate.
The purpose of the utility model is achieved in that a kind of PVB extruder dedicated gear pump; In the pump housing, be arranged with the live axle and the driven shaft that are installed on the pump housing sidewall in parallel; Intermeshing pressure gear all is installed on live axle and the driven shaft; Be formed with admission chamber between intermeshing two pressure gears and the pump housing inwall and go out sap cavity, the pump housing sidewall of admission chamber is provided with material feeding mouth, and the pump housing sidewall that goes out sap cavity is provided with discharge port; Described live axle stretches out outside the pump housing and is connected with the driving shaft of power equipment, is provided with to be connected on the pump housing sidewall at material feeding mouth and discharge port place and uses screw.
Be provided with bearing support and bearing between above-mentioned live axle and driven shaft and the pump housing sidewall.
Above-mentioned power equipment is a direct current generator.
The utility model is compared the outstanding advantage of existing technology and is:
1, the utility model need not adorned seal ring, can not occur melt yet and reveal, and sealing is high.
2, the utility model need not lubricate, high working efficiency.
