It is generally used for the height ofthree point eightLarger space above M, such as airport, station waiting hall, exhibition center, theater, gymnasium, industrial plant, etc.
The surface of the tuyere is equipped with adjustable blade and diffuser. The blade is designed according to the principle of fluid dynamics, which can make the air flow form a vortex flow with a certain initial velocity, so that the air supply range is long, the jet coverage is large, and the convection effect of the air flow is increased.
The blade can change the air supply angle according to the different air supply conditions, and the blade adjustment can be completed manually or electrically.
The outer frame adopts high-quality aluminum plate spinning forming process, with high overall strength and beautiful appearance. The surface can be electrostatic sprayed with decorative requirements.
It can be used with the air volume regulating switch.
classification Swirl tuyere can be divided into manual swirl tuyere and electric swirl tuyere. Manual swirl tuyere: the corresponding angle must be manually adjusted to supply air. Electric actuator type: the electric swirl tuyere can be controlled by switch, and the air volume can be adjusted by 220 V electric control blade, which can be adjusted to the air supply angle at will. Temperature control type (temperature sensitive type): the temperature sensitive swirl tuyere neck is equipped with a temperature sensing actuator, which can automatically sense the air flow temperature and automatically drive the inner blade to change the air supply angle.When the supply air temperature in summer is less than or equal to 17 ℃, the blade can automatically adjust to the cooling mode, and the air flow will blow out horizontally; when the air supply temperature in winter is more than or equal to 27 ℃, the blade can automatically adjust to the heating mode, and the air flow will blow out in the vertical direction.It can meet the air supply requirements under different conditions in winter and summer.The temperature sensing actuator has the advantages of energy saving, environmental protection, stable performance, easy installation and maintenance free without manual or power supply and electronic control equipment. Installation and use Both manual swirl tuyere and electric swirl tuyere are suitable for industrial workshops or high-level activity places.Swirl tuyere can be installed not only in public places (such as industrial plants, airports, theatres, bank business halls, etc.) with large storey height, but also in rooms with storey height ≥ 3.80M (such as conference room), especially suitable for places where the temperature difference of air supply varies from - 10k + 15K. Product selection 1. The main control parameters of swirl tuyere are the type, material, specification, outlet wind speed, total pressure loss and air flow range. 2. The swirl tuyere is mainly made of steel and aluminum alloy. 3. Key points of model selection 1) According to the characteristics of the project, the type of air distribution required, the regulation performance and the air supply mode, the corresponding tuyere type is selected. 2) According to the required air volume [supply air or exhaust (return) air], determine the size of the required air outlet within the allowable wind speed range at the neck of the tuyere (or at the cross section of the inlet and outlet of the tuyere). 3) Check the main technical performance of the selected tuyere, such as range, pressure loss, noise index, wind speed and temperature difference in the working area. 4) Determine the layout and installation mode of the selected tuyere and the connection mode with the air duct. Construction and installation 1. Check the mechanical properties of the air outlet before installation. a) The moving parts of the tuyere should be able to move freely, with uniform damping and no jamming and loosening. b) For products with adjustable or detachable deflector, it is required to adjust and disassemble conveniently and reliably, and there is no looseness after positioning. 2. The surface decoration surface of tuyere shall be flat, the blade distribution shall be uniform, the color shall be consistent, and there shall be no obvious scratch and indentation. The allowable deviation of tuyere should be in accordance with table 2.
