Abstract

PURPOSE:To improve the productionability considerably when compared with additional tightening or adhering by performing supersonic deposition of front and rear face shrouds while to facilitate deposition by providing projections continually and releasing air in hollow section to the outside during supersonic deposition. CONSTITUTION:While contacting the projection 5 on the front face shroud 1 against the rear face shroud 6, supersonic vibration is applied onto the projection 5 to fuse it thus to secure both shrouds 1, 6. Consequently, the productionability is improved considerably when compared with additional tightening or adhesion. Since continual projections 5 will enable releasing of air in the hollow section 4 to the outside without compression, during supersonic deposition, supersonic deposition can be facilitated. While since deposition is performed in a groove 7, positioning of both shrouds 1, 6 during supersonic deposition is facilitated to integrate them completely without causing defective adhesion due to micro vibration caused through supersonic wave or shifting of axis resulting in improvement of adhesion strength.

あった。A known method for manufacturing a conventional synthetic resin pump impeller is to manufacture the shroud and the rear shroud separately due to the structure of the mold, and then integrally form them together by crimping or bonding. However, this manufacturing method resulted in extremely poor productivity. In particular, manufacturing methods using adhesives have problems such as unevenness in the adhesive surface, which can cause imbalance in the impeller, and low adhesive strength, which can cause noise and vibration when using the pump, and peeling of the adhesive. there were.

Since the front shroud 1 and the rear shroud 6 are ultrasonically welded, productivity can be significantly improved compared to methods of caulking or gluing. In addition, since the protrusions 5 are provided intermittently, the air accumulated in the hollow part 4 can be released to the outside without being compressed during ultrasonic welding.
Ultrasonic welding can be easily performed. Furthermore, since welding is carried out within the concave groove 7, the positioning of the front shroud 1 and the rear shroud 6 can be easily performed during ultrasonic welding 12, and at the same time, the slight vibrations caused by the ultrasonic waves may cause adhesion failure or misalignment of the axis. The two can be completely integrated without any problems, and the adhesive strength can be increased.

Can be welded under appropriate welding conditions such as applied pressure. Therefore, it is possible to prevent the base material from being strained, and also to prevent the impeller from being deformed due to the applied pressure, and the variation in the width dimension of the waterway 2 of the impeller is reduced, so that stable water pumping performance can be obtained.

Further, protrusions 5 are formed intermittently on the rear end surface of the blade portion 3 within a range that can ensure sufficient peel strength so as to be dissolved by ultrasonic waves. The tips of the protrusions 5 are made at acute angles so that they can make broad line contact because the smaller the area of the temperature rise part when vibration is applied by ultrasonic waves, the easier it is to melt. On the other hand, the rear shroud 6 is made of synthetic resin.
