Description
Technical field
The present invention relates to a kind of manufacturing methods of centrifugal pump spiral pressurized water chamber pump housing, are especially requiring machining high-precision
The centrifugal pump body of closing, semiclosed cavity surface with surface roughness or the part manufacturing process of other similar surfaces.
Background technique
For fluid-operated centrifugal pump application in many occasions, as spacecraft temperature control system liquid circulation loop,
Numerous departments such as various fluid circuits, fluid delivery system, delicate metering, chemical industry, pharmacy, industrial production, technology belong to fluid
Mechanical big scope.As shown in Figure 1, the manufacturing process of existing hemi-closure space centrifugation water-pumping chamber is using casting, it is difficult to obtain
High machining accuracy and surface roughness, to influence the overall performance of centrifugal pump
Summary of the invention
The present invention provides a kind of manufacturing method of centrifugal pump spiral pressurized water chamber pump housing, can obtain the semiclosed sky of high-precision
Between the pumping chamber pump housing.
The present invention is realized by the following scheme:
A kind of manufacturing method of the centrifugal pump spiral pressurized water chamber pump housing, comprising:
Pump Body Parts to be processed are designed to two half-finished parts, two parts are subjected to roughing or half finishing respectively
Work processes the pumping chamber curved surface spiral flow channel that size and surface roughness all meet required precision；
Using the coaxial relationship of pump housing outlet taper hole and pumping chamber and the circumferential position relationship of two half-finished parts, lead to
Laser welding is crossed, is welded on the cylindrical surface of cooperation；
It is finished in weld seam end surface side, is then again finally completed the finishing of rest part.
Further, described to be designed to that two half-finished parts, a part are pump housing overall structures along pumping chamber axial direction
Median plane and preset radial dimension are cut, another part is the part cylindrical body scaled off.
Further, the radial dimension is to be less than pump housing cylindrical section minimum profile size greater than pumping chamber maximum outside diameter.
Compared with the prior art, the invention has the advantages that: the present invention is suitable for the metal of welding usability and non-
Metal material can obtain 6 grades of machining precision and 1.6 μm of surface roughness.Claimed is such technique knot
Structure design and process.
Detailed description of the invention
Fig. 1 is for centrifugal pump body structure chart；
Fig. 2 is two parts processing structural schematic diagram of centrifugal pump body of the present invention.
Specific embodiment
As shown in Figure 1, centrifugal pump body structure includes: inlet and outlet, pumping chamber, sealing surface, wherein pumping chamber is in half and seals
Space is closed, and is spiral shape, radial section is different on different angles of circumference, therefore the cutting of its high-precision and surface roughness
Processing is difficult to realize.
Pump Body Parts to be processed are designed to that two half-finished parts carry out roughing and semifinishing respectively by the present invention,
The structure designs of two half-finished parts as shown in Fig. 2, a part be pump housing overall structure along pumping chamber axial centre face and
Radial dimension (being greater than pumping chamber maximum outside diameter, be less than pump housing cylindrical section minimum profile) appropriate is cut, another part is exactly
Then two parts are carried out roughing or semifinishing by the part cylindrical body scaled off respectively, process size and surface is thick
The pumping chamber curved surface spiral flow channel that rugosity is all met the requirements, and guarantee the cooperation cylindrical surface dimensional tolerance of two parts, reach
Microgap cooperation, while the relationship coaxial using pump housing outlet taper hole and pumping chamber, guarantee two seperated circumference using tooling
Positional relationship is to be welded on the cylindrical surface of cooperation then by laser welding, is carried out again after welding in weld seam end surface side several
Ten microns of end faces to 0.2mm finish, and then again finally complete the finishing of rest part, the seperated size of technique processing
It is determined by the size of specific part, structure situation.
Going out two seperated half-finished parts with titanic alloy machining, pump housing full-size is 82mm × 74mm × 44mm, point
Body small part is processed after the completion of (pumping chamber is partially completed whole finishing) having a size of 48 × 7.3mm of Φ, two parts semifinishing
By being laser welded.
There is the pump housing pumping chamber type face of degree of precision and surface roughness to can choose point for being enclosed in internal requirement
The pump housing is made into part by face, after processing inner cavity respectively, is selected suitable welding surface to carry out one entirety of welding, is guaranteed weldering
The linking intensity of junction and sealing, to realize the processing of the high-precision pump housing.Require welding indeformable after to processing or deformation
High-precision Laser Welding is used under conditions of very little.
Specific embodiments of the present invention are as shown in Figure 2: the cylindrical section of centrifugal pump body is having a size of Φ 50mm × 14.3mm, pressure
For the radius of water chamber from 16.7mm to 21.7mm, the seperated small part of fractionation processes pumping chamber having a size of 48 × 7.3mm of Φ respectively
And other Each parts, seal face stay 0.1mm to 0.2mm machining allowance, are finished after welding.
