Abstract
The invention relates to a special external transducer speeder for mine ventilator. The invention mainly solves the technical problem that the existing fan transducer speeder is poor in heat dissipation effect. The invention has the technical scheme that: the two ends of a fan runner (9) are respectively provided with a connecting flange (1), the outer wall tightly close to the fan runner (9) is respectively provided with an explosion suppression connecting line cavity (3) and an explosion suppression control cavity (4), the explosion suppression control cavity (4) is provided with a connecting port (2) and a communication and control line connection port (8), the outer wall tightly close to the fan runner (9) in the explosion suppression control cavity (4) is provided with a transducer electric element (5); and a display window (6) and a control button (7) also can be arranged on the explosion suppression control cavity (4). The transducer speeder electric element is arranged at the outside of the runner wall, the fan runner is utilized for heat dissipation, heat dissipation area is large, thus not only effectively solving the heating problem of transducer speeder power element but also being convenient for installation, debugging and maintenance, thereby improving working stability and reliability. The invention can be widely applied to control on devices such as underground fan, local fan and the like.
Description
Technical field
The present invention relates to a kind of frequency converter speed regulating device.
Background technique
At present, the frequency converter speed regulating device that is used for Equipment Control such as down-hole blower fan, portable blower is equipped with 2 kinds of modes: the one, and adopt independent frequency variator to be installed in outside the runner, its heat diffusion area is little, and radiating effect is poor; The 2nd, frequency variator is installed in the runner, but its installation, debugging, maintenance and maintenance are all not too convenient, and the fan operation runner is had resistance.
Summary of the invention
The purpose of this invention is to provide a kind of good heat dissipation effect and installation, debugging, maintenance and special external transducer speeder for mine ventilator easy to maintenance.
The technical solution adopted for the present invention to solve the technical problems is: be respectively arranged with adpting flange 1 at the two ends of blower fan runner 9; The outer wall of being close to blower fan runner 9 is provided with flame proof control chamber 4; Outer wall at flame proof control chamber 4 inner close fitting blower fan runners 9 is installed frequency variator electric elements 5, and flame proof control chamber 4 is provided with connection jaws 2, communication and guide line connecting port 8.
Another embodiment of the invention is: be respectively arranged with adpting flange 1 at the two ends of blower fan runner 9; On the outer wall of being close to blower fan runner 9, be respectively arranged with explosion insulation connecting line cavity 3 and flame proof control chamber 4; Explosion insulation connecting line cavity 3 is provided with connection jaws 2, communication and guide line connecting port 8, at the outer wall of flame proof control chamber 4 inner close fitting blower fan runners 9 frequency variator electric elements 5 is installed.
The present invention also can be provided with display window 6 and control button 7 by flame proof control chamber 4.
The present invention utilizes the blower fan runner to dispel the heat through the RHVC electrical apparatus element being installed in the flow path wall outside, and heat diffusion area is big, but efficiently radiates heat.Its maintenance, easy to maintenance quick.On the other hand, big because of the space that electric elements distributes, be easier to install and debugging.It had both solved the heating problem of RHVC power component effectively, had made things convenient for maintenance, maintenance again, had improved working stability and reliability.It can be widely used in the control of the equipment such as blower fan, portable blower of down-hole.
