Title: Huan-Jan Chien: Innovator in Pump Technology
Introduction
Huan-Jan Chien is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the field of pump technology, holding a total of 12 patents. His innovative designs focus on enhancing the efficiency and functionality of various pumping systems.
Latest Patents
One of Huan-Jan Chien's latest patents is a device of a volute channel of a pump. This device is contained in a circular casing and works in conjunction with a rotational impeller to pump and deliver fluid. The design features a volute channel structure that is a spiral volute channel surrounding the impeller exit side. The leading edge of the volute channel is designed with a water-cut angle, and the sectional area of the channel is wider and deeper from this angle. The outer diameter of the volute channel is arranged concentrically, and the throat partition connects to the rear edge of the volute channel, extending toward the exit of the casing. This innovative design allows the volute channel to surround the impeller exit side over 360 degrees.
Another significant invention is the structure for an oxygen adding and aeration device. This improved structure includes a pump and a two-layer impeller installed on top of the pump. The design features a pump case that covers the two-layer impeller and an air tube installed in the impeller inlets of the lower-layer impeller. When the pump is activated, the two-layer impeller delivers air from the air tube into the lower-layer impeller, mixing it with water to create an air-water flow. This design enhances the oxygenation of water, making it more efficient for various applications.
