Problems solved by technology

[0003] The traditional inlet guide vane adjustment device mostly uses a crank-link mechanism, driven by a pneumatic actuator, and adjusts the blade angle through transmission parts. This kind of regulator has a complex structure, many transmission parts, large power consumption, and poor angle adjustment accuracy. Drive lock occurs
Some existing inlet guide vane adjustment devices adopt a gear transmission structure. This type of regulator can adjust the rotation angle of the guide vane more accurately, but in the case of adjusting the inlet flow and pressure. The bevel teeth are subjected to a large bending moment when rotating, which is prone to transmission difficulties and even stuck problems

Abstract

The invention relates compressor equipment, particularly to an inlet guide vane adjusting device of a compressor. The inlet guide vane adjusting device of the compressor comprises guide vane blades, a guide vane seat, a blade transmission shaft, a guide vane housing and a stepping motor, wherein the stepping motor is fixed onto the guide vane housing. The inlet guide vane adjusting device of the compressor also comprises a connecting rod linkage device and a diversion blade linkage device, wherein the connecting rod linkage device is composed of a large chain wheel, a fixing base, a small chain wheel, chains and a connecting rod; the diversion blade linkage device comprises a main belt pulley, an auxiliary belt pulley, a transmission wheel and transmission belt wires. The inlet guide vane adjusting device of the compressor can precisely control the rotation angle of the guide vane blades and achieve stepless adjustment of air suction quantity; by means of chain transmission and belt transmission, is stable in transmission, achieves buffer and shock absorption, has a high transmission efficiency and can work in high-pressure, high-temperature or moisture environments; is small in integral size and simple in structure.

Description

technical field [0001] The invention relates to compressor equipment, in particular to a compressor inlet guide vane adjustment device. Background technique [0002] As an energy-saving and environmentally-friendly technology, large-capacity centrifugal heat pump units are increasingly favored by people, especially the development of medium-high temperature heat pump technology that uses industrial wastewater as a low-level heat source, which is very important for domestic heating and other heating in urban areas in northern my country. field is very important. The inlet guide vane adjustment device is one of the main control components of the centrifugal heat pump. When the compressor starts and stops or operates under partial load, the suction volume of the compressor can be controlled by controlling the rotation angle of the inlet guide vane to ensure the safe operation of the unit. Improve unit operating efficiency. Centrifugal heat pump units, especially medium and hig...
