Abstract
The utility model provides a high-power blower provided with an automatic valve mechanism, wherein an air cylinder fixing seat is mounted on a blower body; an air cylinder is mounted on the air cylinder fixing seat; and the other end of the air cylinder is connected with an air door handle capable of opening and closing a rectangular valve door body. The air cylinder and the air door handle are under the program control of a PLC (programmable logic controller) program. Before a motor is started, a rectangular valve door body is closed, so as to enable the load of the blower to be the minimum; at the same time, the motor is started, then the starting current is the minimum; and after the motor is started to operate, the rectangular valve door body is automatically opened. By adopting the high-power blower provided with the automatic valve mechanism, tripping is avoided, starting equipment is prevented from being damaged, energy source is saved, and the service life of the motor is prolonged.
Description
Technical field
The utility model relates to high-power blower, specifically has the high-power blower of automatic valve mechanism.
Background technique
Existing high-power blower in start-up course, the protective switch tripping operation occurs through regular meeting; Perhaps, because the impact of great start-up current, and damage starting device and lead.
Summary of the invention
The purpose of the utility model is the inrush current that reduces blower fan, avoids the tripping operation that causes because of startup, and the protection starting device prolongs electrical machinery life, energy saving.
The utility model is to realize purpose of design like this:
Cylinder fixed base 2 is installed on blower fan body 1; Cylinder 3 is installed on the cylinder fixed base 2; The other end of cylinder 3 links to each other with the air door handle 5 that can open and close rectangle valve body 8.Closing and open by cylinder 3 and air door handle 5 of rectangle valve body 8 accomplished; Cylinder 3 and air door handle 5 receive the program control of PLC.
During use, before starting electrical machinery,,, close rectangle valve body 8 through cylinder 3 and air door handle 5 according to the PLC program; Make the load of blower fan minimum.At this moment, starting electrical machinery 7, inrush current are also minimum.By the time motor 7 startups finish, and when being in running state, under the control of PLC program, rectangle valve body 8 is opened automatically.Like this, protective switch and starting device just can successfully " be hided " and crossed the peak value of inrush current.Therefore tripping operation can be do not caused, starting device can be do not damaged yet, simultaneously, because inrush current is little, all right energy saving, the life-span of prolongation motor 7.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, a non-limiting examples is explained.
Cylinder fixed base 2 is installed on blower fan body 1; Cylinder 3 is installed on the cylinder fixed base 2; The other end of cylinder 3 links to each other with the air door handle 5 that can open and close rectangle valve body 8.Closing and open by cylinder 3 and air door handle 5 of rectangle valve body 8 accomplished; Cylinder 3 and air door handle 5 receive the program control of PLC.
During use, before starting electrical machinery,,, close rectangle valve body 8 through cylinder 3 and air door handle 5 according to the PLC program; Make the load of blower fan minimum.At this moment, starting electrical machinery 7, inrush current are also minimum.By the time motor 7 startups finish, and when being in running state, under the control of PLC program, rectangle valve body 8 is opened automatically.Like this, protective switch and starting device just can successfully " be hided " and crossed the peak value of inrush current.Therefore tripping operation can be do not caused, starting device can be do not damaged yet, simultaneously, because inrush current is little, all right energy saving, the life-span of prolongation motor 7.
