Abstract
The invention discloses an improved structure for the pump shell of a booster pump. The pump shell consists of two halves of the pump shell and a temperature-resistant sealing glue layer is adopted to seal the middle open side between the two halves of the pump shell. The up-and-down part between the pump shell and the bearing body of an existing bearing component at the non-driving end and an existing bearing component at the driving end is connected by a bolt. The pump shell and the existing cooling cavity cap are connected by a rabbet method; a spring energy storage seal and an O-shaped seal ring are used for the sealing between the cooling cavity caps on both sides of the rabbet and the pump shell; the existing mechanical seal component is fixed on the cooling cavity cap with a bolt and the cooling cavity cap is formed by welding forged parts. By design improvement, the defects of the original design are eliminated and the operating safety and reliability of the pump are improved.
Description
Technical field
The present invention relates to a kind of pump case of front-mounted pump, particularly a kind of structure-improved of booster pump case.
Background technique
Existing booster pump case is important part in the front-mounted pump, and the design quality of pump case directly has influence on the quality of front-mounted pump, and there is following defective in the pump case of front-mounted pump in design at present:
1, pump case in open face seal and with cooling chamber capping fitting surface processing difficulties, cause leakage easily.
2, the unreasonable installation of the screwhole position that connects design with the cooling chamber capping is difficult; The bore dia that matches with the cooling chamber capping in the pump case is smaller, causes the inner difficulty of processing of pump case big.
3, having only Lower Half to be connected and fixed between pump case and the bearing support makes the unbalanced bearing that causes of the hot operating mode lower stress of bearing bear the load increase.
Because some designs of existing front-mounted pump and manufacturing deficiency cause the operational reliability of pump poor, have increased the operating cost of power plant.
Summary of the invention
Technical problem to be solved by this invention provides a kind of structure-improved of booster pump case, to solve the existing existing many deficiencys of booster pump case.
Technical problem to be solved by this invention can be achieved through the following technical solutions:
A kind of structure-improved of booster pump case is made of two halves, it is characterized in that, opens between the two halves pump case and adopts the refractory seal glue-line to seal on the face.
In the present invention, top and the bottom Bolt Connection between the bearing support of described pump case and existing non-transmision end bearing part and driving end bearing part has guaranteed that shaft strength evenly particularly under hot thermal distortion does not take place.
In the present invention, adopt the seam mode to connect between described pump case and the existing cooling cavity capping, between the cooling chamber capping of described seam both sides and pump case, adopt spring energy-storage sealing and two road O-ring seals to seal; The existing mechanical sealed member is installed in the described cooling chamber capping by bolt, and described mechanical seal parts carry out fastening with the fixing of axle with clamping ring; Described cooling chamber capping adopts the forging welding to constitute.
The pump case of front-mounted pump of the present invention by above-mentioned improvement after, have following advantage:
1, pump case in open face and adopt the refractory seal glue-line to seal, be not easy to occur leakage phenomenon.Increased in addition and the cooling chamber capping aperture that matches, thereby guaranteed the machining accuracy of pump case inside.
2, adopt the seam mode to connect between pump case and the cooling chamber capping and be furnished with spring energy-storage sealing and O-ring seals, solved sealing surface between cooling chamber capping and the pump case and be in operation and the problem of leaking occurs, it is easier that the cooling chamber capping is installed.It is fastening that the mechanical seal parts adopt clamping ring to carry out, and increase working life, the possibility that having reduced is in operation occurs leaking.The present invention is arranged on the cooling chamber and the Seal cage of cooling chamber capping on the same diametric plane basically, has shortened axial length, has reduced the length of pump, and the rigidity of pump is increased.The cooling chamber capping adopts the forging welding to constitute, and its shape is simplified more, has stopped the generation of water leakage phenomenon.
3, increased and the cooling chamber capping aperture that matches, thereby guaranteed the machining accuracy of pump case inside.
4, top and the bottom Bolt Connection between pump case and the bearing support has guaranteed that shaft strength evenly particularly under hot thermal distortion does not take place.
