Abstract

The invention discloses a hydraulic centrifugal fan of an optimized structure. The hydraulic centrifugal fan comprises a support, a spiral casing, a vane wheel, a motor and a valve block. The spiral casing is fixed to the support through a bearing base. The motor is fixed to the bearing base, and a rotating shaft of the motor extends into the bearing base and is fixedly connected with a transmission shaft. Multiple grooves in linear arrangement are formed in the outer wall of the transmission shaft. One end of a locating rod is connected into the corresponding groove in an inserted manner. Thelocating rod is connected into a storage groove of a support seat. An annular through groove is formed in the outer side wall of the bearing base and communicates with the transmission shaft. The support seat is connected into the through groove in an inserted manner. The other end of the locating rod penetrates out of the support seat and is provided with a pull ring. One end of the pull ring penetrates out of the through groove. The part, located inside the storage groove, of the locating rod is provided with a baffle. The two ends of a compressed spring abut against the baffle and the inner wall of the storage groove correspondingly. By means of the hydraulic centrifugal fan, the problem that common fans cannot be modified due to fixed structures can be solved.

Description

Technical field: [0001] The invention relates to the technical field of centrifugal fans, in particular to a structurally optimized hydraulic centrifugal fan. Background technique: [0002] The hydraulic centrifugal fan can be used as a power fan in the air supply system or exhaust system. No viscous substances are allowed in the gas, and it can be used to transport gas in an environment where the gas temperature does not exceed 80 degrees Celsius. Most of the existing hydraulic centrifugal fans have a uniform structure and size. When encountering special circumstances, it is necessary to modify parts of the fan (such as the structure of the impeller), which becomes quite troublesome. [0003] In view of the above-mentioned defects, the designers are actively researching and innovating in order to create a hydraulic centrifugal fan with a new structure and optimized structure, so that it has more industrial value. Invention content: [0004] The purpose of the present inv...
