Problems solved by technology
But there are still many disadvantages in this way: after the failure of the intelligent adjustment instrument or the failure of the wind pressure transmitter, the frequency of the inverter cannot be adjusted during the maintenance period, and the frequency converter runs at the maximum frequency by default, resulting in a waste of electric energy

Embodiment Construction
[0008] Illustrate the present invention below in conjunction with accompanying drawing:
[0009] Such as figure 1 As shown, the woodworking environmental protection dust removal fan control system of the present invention includes an electrical control cabinet 1 and a cabinet door 2 arranged thereon. The electrical control cabinet 1 includes a frequency converter 3 and a wind pressure transmitter 4. The cabinet door 2 is provided Intelligent regulator 5, manual automatic transfer switch 6, wind pressure transmitter 4 is connected to dust removal pipe 7 through wind pressure transmission pipe 8, manual automatic transfer switch 6 is connected to frequency converter 3 through wires, and intelligent regulator 5 is connected to the dust removal pipe 7 through wires. Connect with frequency converter 3 and wind pressure transmitter 4.
[0010] figure 2 It is a schematic diagram of the front side of the electric control cabinet of the present invention. An intelligent regulator 5 ...

The invention relates to electric control equipment, and particularly to a control system for a woodworking environment-friendly dust removing blower, which comprises an electrical control cabinet 1 and a cabinet door 2 arranged on the electrical control cabinet 1, wherein a frequency converter 3 and a wind pressure transducer 4 are arranged in the electrical control cabinet 1; an intelligent regulating instrument 5 and a manual-automatic transfer switch 6 are arranged on the cabinet door 2; the wind pressure transducer 4 is connected to a dust removing pipeline 7 through a wind pressure transmission pipeline 8; the manual-automatic transfer switch 6 is connected with the frequency converter 3 through a conducting wire; and the intelligent regulating instrument 5 is connected with the frequency converter 3 and the wind pressure transducer 4 respectively through conducting wires. According to the control system, when the intelligent regulating instrument or the wind pressure transducer breaks down, a user can switch the manual-automatic transfer switch to a manual gear during maintenance, and the output frequency of the frequency converter is adjusted manually according to the intensity of a current productive task, so as to save electric energy to the utmost extent.
Description
technical field [0001] The invention relates to an electrical control system, which is applied to a frequency conversion control system of a woodworking environmental protection dust removal fan. technical background [0002] In the drive control of woodworking dust removal fans, the production tasks (the number of woodworking machines) are different, and the loads are different, so the required power is different. In the traditional fan control, once the fan motor is started, it will run at the rated speed. No matter how many production tasks (the number of woodworking machinery is opened), the fan motor will run at the rated speed. In the case of a large number of woodworking machinery), the air volume is not enough, the air pressure cannot meet the requirements of environmental protection, and the dust removal effect is not good; in the case of few production tasks (the number of woodworking machinery is small), the air volume is large, and the wind The pressure is super...
