Description
Technical field
The present invention relates to a kind of jet and centrifugal pump, more precisely, being the jet and centrifugal pump being related to a kind of use sheet stamping and welding fabrication, this jet and centrifugal pump is used for conveyance fluid.
Background technology
Jet and centrifugal pump is by jet pump and the charge-coupled product being combined on a unit of centrifugal pump, mainly uses in domestic and civil area.The pump housing of jet and centrifugal pump of routine, pump cover, impeller are mostly by casting, and mjector most common plasticses part injection mo(u)lding, then each parts assembly is become a water pump.The pump component of iron casting molding extremely gets rusty easily, and outward appearance unsightly, is easily caused fault or damage, more because ferrum gets rusty forms pollution so as to purposes is significantly limited to conveyance fluid；The pump component processing of rustless steel casting is relatively difficult, and material price is high；The pump component weight weight of copper casting, price is high.So, the conventional centrifugal pump based on casting part can not meet simultaneously price suitably, hygienic environment-protecting, requirement durable, easy to process.
Content of the invention
It is an object of the invention to create a kind of price suitably, health, jet and centrifugal pump durable, easy to process.For this purpose, employ the jet and centrifugal pump of a kind of sheet stamping and welding fabrication, described thin plate can be the light sheet material that stainless sheet steel or other are difficult corrosion.Because light sheet material relative weight is light, can be with material-saving cost；Due to being difficult corrosion it is possible to accomplish hygienic environment-protecting, durable；Due also to punching press and welding fabrication technique are simple, more with short production cycle than metal casting processing, parts are not processed or few processing, also reduce further cost.But because sheet stamping and welding fabrication are differed widely with the technique of casting, need refitting to design a kind of and original jet and centrifugal pump different structure of structure, sheet stamping and the jet and centrifugal pump of welding fabrication just can be made to realize its function.
The newly-designed structure that the present invention adopts is as shown in Figure 1：By pump cover（2）, pump case（5）, support（4）, suck room cover plate（3）, jet pipe（6）, flow guiding disc（7）, impeller（8）, sealing member（9）, axle（10）Composition, is characterized in that pump cover（2）, support（4）, pump case（5）, suck room cover plate（3）, jet pipe（6）, flow guiding disc（7）Formed for sheet stamping, thin plate can be the light sheet material of carried out punching press required by stainless sheet steel or other user and stretching；By pump cover（2）, pump case（5）The shell that welding forms jet and centrifugal pump is overall, the suction chamber of pump（1）By suction room cover plate（3）With support（4）Panel welding is formed, the suction chamber after welding（1）With jet pipe（6）Welding forms the mjector of pump；Flow guiding disc（7）In pump case（5）Plane（11）Place is with being welded and fixed；Impeller（8）It is in pump case（5）With flow guiding disc（7）In the space being formed；Sealing member（10）It is installed on pump case（5）Outer sealing member position, axle（10）Through sealing member（9）Afterwards, axle（10）The thread of front end screws in impeller（8）On screw and impeller（8）Connection.
Nozzle before welding fabrication, in Fig. 1（12）Directly sucking room cover plate（3）Upper stretching mode molding, that is, suck room cover plate（3）Before pump assembling, there is nozzle（12）.
Fig. 2 is the partial enlarged drawing at A in Fig. 1.As shown in Fig. 2 the pump cover in the present invention（2）And pump case（5）Using butt welding molding, because of the requirement in pump exterior appearance, it is designed to gap filling formula butt welding, so that surface polishes smooth after welding；Meanwhile, pump cover（2）And pump case（5）Using the needs positioning during butt welding, therefore design support（）Cylindrical extend back so that pump cover（2）And pump case（5）Support can be enclosed within（4）Cylindrical upper positioning, and make pump cover（2）And pump case（5）Between formed a gap ring（13）, by welding this gap ring（13）Filling, thus by pump cover（2）, pump case（5）, support（4）It is welded into an entirety.
For realizing said structure, as shown in each part is in the rigging position of Fig. 1, the assembling of pump and the step of welding are：
1）By jet pipe（6）With support（4）Carry out sealing welding；
2）By jet pipe（6）With flow guiding disc（7）Carry out sealing welding；
3）By water inlet pipe（14）With suction room cover plate（3）Sealing welding, then room cover plate will be sucked（3）With the aforementioned support welding（4）Sealing welding；
4）By impeller（8）Put into pump case（5）In；
5）By the support being welded（4）Put into pump case（5）, now flow guiding disc cover impeller（8）, pump case（5）To position flow guiding disc（7）, concentric to ensure it；
6）Plumb joint passes through support（4）On through hole by flow guiding disc（7）Spot welding is fixed on pump case（5）Face（11）On；
7）By pump cover（2）It is enclosed within support（4）Cylindrical on, and and pump case（5）Form the annular gap of 1.5mm（13）；
8）By annular gap（13）With welding filling, make support（4）, pump case（5）, pump cover（2）Three's welding is integral；
9）By sealing member（10）Install into pump case（5）Sealing member（10）Position；
10）By axle（10）Sealing member is passed through outside pump（10）, and the thread of axle front end is screwed in impeller（8）On screw.
Embodiment 1
Shown in Fig. 1 is exactly a jet and centrifugal pump being available for realizing the stainless sheet steel punching press and welding fabrication using.Pump can be by motor-driven, pump and motor coaxle.Its operation principle is：In pump, first inject fluid, prime mover band moving axis and wheel rotation, impeller（8）In fluid move out formation pressure under the influence of centrifugal force, a part of fluid is through outlet（15）Outwards conveyance fluid, another part fluid reflux is to nozzle（12）, through nozzle（12）Fluid high-speed is injected into jet pipe（6）, nozzle（12）The fluid of outside enters jet pipe under jet drive（6）, thus the water inlet in pump（14）Produce negative pressure；On the other hand, impeller（8）In fluid motion also will be in impeller（8）Water inlet produce negative pressure, pump water inlet mouth（14）Fluid outside pipeline is inhaled into suction chamber by the collective effect of this two negative pressure（1）In, thus realizing the function of jet and centrifugal pump conveyance fluid, during pump work, the direction of motion of fluid is as illustrated by the arrows in fig. 1.
