Fig. 2 is the inner structure scheme drawing of vacuum screw rod transmission pump;
Fig. 3 is vacuum chamber, the feed cavity of vacuum screw rod transmission pump, the assembly drowing in discharging chamber.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is carried out detailed explanation.
As shown in Figure 1, vacuum screw rod transmission pump provided by the present invention comprises the feed cavity 5 and discharging chamber 6 that is interconnected, and the top of feed cavity 5 is provided with inlet point 4; The end in discharging chamber 6 is provided with discharging opening 7; Wherein, be connected with vacuum chamber 3 at the opposite side of feed cavity 5 with respect to discharging chamber 6, vacuum chamber 3 is provided with blow off valve; The opposite side of vacuum chamber 3 is provided with gear case 2, and the screw rod that is driven by motor 1 runs through vacuum chamber 3 and feed cavity 5 successively.
As shown in Figure 2, the vacuum screw rod transmission pump that present embodiment provided comprises that 10, two screw rods of two screw rods are parallel to each other in vacuum chamber 3 and feed cavity 5; Screw rod 10 is provided with conveyor screw; The end of two screw rods 10 connects transmission shaft respectively, and wherein main driving axle 9 is connected through the device that is flexible coupling with motor 1, and transmission shaft is arranged in the gear case 2; Be provided with in the described gear case 2 respectively and be connected with driven transmission shaft 11 and intermeshing synchronizer gear 12 with main driving axle 9; When main driving axle 9 was rotated by driven by motor, driven transmission shaft 11 was driven through the rotation of synchronizer gear 12, thereby two screw rods are rotated synchronously.Junction in feed cavity and discharging chamber is provided with bearing support 8.The present invention is not limited to adopt the twin screw transmission pump of cross-compound arrangement, adopts single screw rod transmission pump of single-shaft configuration or three screw rod transmission pumps of three-axis structure etc. all to be applicable to mentality of designing of the present invention.
As shown in Figure 3, the blow off valve that is arranged on the vacuum chamber 3 comprises valve seat 15 and spool 18, and spool 18 is provided with pull back spring 17, and pull back spring 17 upper ends are provided with look nut 16, and valve seat 15 is provided with the vacuum tube joint 19 that is used to connect vacuum suction device.The part of screw rod 10 in vacuum chamber 3 is provided with vacuum screw body 12, and the part of screw rod 10 in feed cavity 5 is provided with pushing spiral body 13.Because the spiral thrust effect of vacuum screw body 14 is offset with the pull of vacuum of vacuum chamber, material is difficult for getting in the vacuum chamber, has only gas to be drawn out of from vacuum chamber.This structure design makes feed cavity only receive the suction pressure effect, compact conformation, and strong from absorption, spillage is little.The bearing of transmission shaft adopts lubricating oil (fat) lubricated separately, not influenced by pumped (conveying) medium, drives with a pair of synchronizer gear between two screw rods, can carry various non-lubricity materials.
