Technical field
The invention belongs to field of vacuum, particularly one is used in RH, VD(VOD) the split type water vapor vacuum pump of one in equipment for vacuum refining.
Background technique
The function of the outer purifier of vacuum furnace is that molten steel is carried out to vacuum circulation degassing, and degassed vacuum pump used is water vapor vacuum pump, taking steam as propellant, by Laval nozzle, produces ultrasonic jet, and the waste gas during by application of vacuum is taken away.
At present, known in RH external refining system, before the two-stage steam ejection vacuum pump pump housing be overall structure, its boundary dimension is larger, especially length dimension is very large, the nearly 30m of vacuum pump length having used now.This transport to vacuum pump, installs and brings very large difficulty; And using after the several years, integral replacing vacuum pump almost cannot be realized.
Common flange connects, and especially connects large-scale pipeline, although can solve the problem of transport, cannot realize at the scene accurately centering, and installation is wasted time and energy, and in use also cannot ensure the rigidity of pump housing joint.
Summary of the invention
The object of the invention is to design a kind of split type steam ejection vacuum pump, to facilitate transport and quick installation of vacuum pump, and realize the parts replacement of large-scale steam ejection vacuum pump.
The present invention solves the technological scheme that its technical problem adopts:
A kind of split type steam ejection vacuum pump, comprises the pump housing one, the pump housing two and pump housing connection set, and 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, forms guide surface, and the outer surface of the described pump housing two is 15 °～30 ° angles, also forms guide surface;
The pump housing two stretches out the part of flange two and the endoporus of flange one forms Spielpassung.
Described pump housing connection set also comprises the sealing gasket being 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 invention has the beneficial effects as follows, the pump housing of hydro-steam ejector pump is divided into two sections by the present invention, between two sections, adopt companion flange and sealing gasket to be fixedly connected with by bolt group, concerning the large-scale steam ejection vacuum pump pump housing, can increase the convenience of the pump housing in transportation process; And partial installation is carried out at the scene of being convenient in the situation that not destroying former steel structure, after in place, be assembled into one, can greatly reduce field erected workload, can also realize the parts replacement of hydro-steam ejector pump, save the device maintenance time, extend the working life of former purifier, can improve the stability of original system simultaneously, for user brings considerable economic benefit.
Below in conjunction with drawings and Examples, invention is further illustrated.
