Abstract

An inlet guide vane assembly is disclosed, which comprises: a housing, configured with a first penetration part and a plurality of first grooves; at least one fixing ring, each configured with a second penetration part and a plurality of second grooves; at least one rotary ring, each configured with a third penetration part and a plurality of sliding chutes, wherein the first, the second and the third penetration parts are arranged in communication with one another; a plurality of vane units, each vane unit is composed of a vane, a linkage and a sliding block; and at least one driving unit, for driving one vane of the plural vanes to swing, thus driving the rotary ring to rotate simultaneously, bringing along the other vanes to swing, enabling the sliding blocks to slide inside corresponding sliding chutes, and consequently flipping the vane from a first state to a second state.

Description

technical field [0001] The invention relates to an air intake guide vane assembly, in particular to an air intake guide vane assembly which simplifies the structure, reduces the difficulty of assembly, reduces the cost and solves the problem of external placement of the actuator. Background technique [0002] The technology of using blade angle to control fluid flow is used in different technical fields. For air-conditioning applications, when the centrifugal compressor operates under different loads, different flow paths must be formed before the impeller inlet by opening and closing the guide vanes. area to adjust equipment load by controlling fluid flow. Therefore, if the intake guide vane at the compressor inlet cannot be accurately controlled, the load of the chiller cannot be controlled, which will inevitably result in serious energy waste. [0003] However, most of the existing air inlet guide vanes are mechanisms that use connecting rods and gears, or drive the toot...
