The utility model solves the technological scheme that its technical problem adopts:
A kind of split type water-vapour spray vacuum pump, comprise the pump housing one, the pump housing two and pump housing connection set, the described pump housing one and the pump housing two are fixedly connected by pump housing connection set,
Described pump housing connection set comprises flange one, flange two, fastening piece, and described flange one and flange two-way are crossed fastening piece and be fixedly connected;
Described flange one is fixedly connected with the pump housing one, and flange two is fixedly connected with the pump housing two;
The endoporus of described flange one is 15 ° ~ 30 ° chamferings, and form guide surface, the outer surface of the described pump housing two is 15 ° ~ 30 ° angles, also forms guide surface;
The endoporus of part and flange one that the pump housing two stretches out flange two forms Spielpassung.
Described pump housing connection set also comprises the sealing gasket be arranged between flange one and flange two.
Described flange one, flange two form seam after connecting, and described seam adopts continuous welding to ensure the tightness of the pump housing.
Described flange one is tightly connected by being welded and fixed with the pump housing one, and flange two and the pump housing two are tightly connected by being welded and fixed.
Described fastening piece is bolt group.
The beneficial effects of the utility model are, the pump housing of steam ejector pump is divided into two sections by the utility model, adopt companion flange and sealing gasket to be fixedly connected with by bolt group between two sections, concerning large-scale water-vapour spray vacuum pump body, the convenience of the pump housing in transportation process can be increased; And partial installation is carried out when not destroying raw steel structure in scene of being convenient to, one is assembled into after in place, field erected workload can be greatly reduced, the parts replacement of steam ejector pump can also be realized, save the device maintenance time, extend the working life of former purifier, the stability of original system can be improved, for user brings considerable economic benefit simultaneously.
Below in conjunction with drawings and Examples, model utility is further illustrated.
Accompanying drawing explanation
Fig. 1 is the structural representation of the split type water-vapour spray vacuum pump of the utility model embodiment;
Fig. 2 is the structure sectional view of the pump housing connection set of the utility model embodiment.
In figure: 1, the pump housing 1, the pump housing two; 3, pump housing connection set; 4, flange one; 5, fastening piece; 6, sealing gasket; 7, flange two; 8, mouth is propped up; 9, guide surface; 10, seam.
Embodiment
Embodiment 1
The split type water-vapour spray vacuum pump of one as depicted in figs. 1 and 2, comprises the pump housing 1, the pump housing 22 and pump housing connection set 3, and the described pump housing 1 and the pump housing 22 are fixedly connected by pump housing connection set 3, it is characterized in that:
Described pump housing connection set 3 comprises flange 1, flange 27, fastening piece 5, and described flange 1 and flange 27 are fixedly connected by fastening piece 5;
Described flange 1 is fixedly connected with the pump housing 1, and flange 27 is fixedly connected with the pump housing 22;
The endoporus of described flange 1 is 15 ° ~ 30 ° chamferings, and form guide surface 9, the outer surface of the described pump housing 22 is 15 ° ~ 30 ° angles, also forms guide surface 9;
The endoporus of part and flange 1 that the pump housing 22 stretches out flange 27 forms Spielpassung.
