Problems solved by technology

In the box-type single-stage air (magnetic) high-speed centrifugal blower in the prior art, in the state of natural flow, the wind speed flowing through the surface of the motor shell in the direction of the motor axis is small and uneven, and the heat generated by the motor is difficult to be completely exhausted in time. Take it away, causing the temperature of the motor to rise too high, the output to drop, or even burn out

Abstract

The invention provides a box-type single-stage direct-connecting high speed blower, and relates to the technical field of a blower. The blower comprises a motor, a fan which is arranged at a shaft end of the motor, and a silencing box body which is arranged outside the motor and the fan; and the blower is characterized by further comprising a baffle which is arranged in the silencing box body, and a cooling air duct which is fixedly connected with the baffle, wherein a box body air inlet is formed on the silencing box body corresponding to the cooling air duct, the diameter at two ends of the cooling air duct is greater than the diameter of the middle part of the cooling air duct, and the motor is placed at the middle part of the cooling air duct. The blower is reasonable in design, convenient and practical; the wind speed flowing through the motor casing is large, the radiation effect is good, and the motor works safely and stably.

Description

Technical field: [0001] The invention relates to the technical field of blowers, in particular to a box-type single-stage direct-connected high-speed blower. Background technique: [0002] Single-stage air (magnetic) high-speed centrifugal blower has outstanding advantages such as simple structure, small size, high efficiency and energy saving, wide adjustment range, etc., and it is the direction of fan development. With the emergence of new technologies and materials and the improvement of the domestic equipment manufacturing industry, the stability of high-speed fans has been greatly improved and the manufacturing cost has been reduced. It can replace most traditional products such as low-speed multi-stage centrifugal blowers and Roots blowers, and the airflow is stable. No pulsation, high efficiency, energy saving and cost reduction. The scope of use of high-speed fans is getting wider and wider, and it has gradually been recognized by users, and the market prospect is b...
