Description

Double-speed motor control method

Technical field

The present invention relates to fire-fighting equipment manufacturing technology field；A kind of double-speed motor applying to control exhaust blower Control method.

Background technology

The at present fire-fighting system in all kinds of buildings, mostly using the concentration of smog as determining whether what fire occurred Foundation, starts fire-fighting system the most immediately once there be fire to occur.And in daily life, often have some slight smog to send out Raw, in order to be got rid of by these smog, and fire-fighting system can not be started it is necessary to arrange another set of smoke evacuation system, two set rows are set Cigarette system will make the burden of the owner of building, and cost increases.

Summary of the invention

It is an object of the invention to provide a kind of double-speed motor control method, it can solve the burden of the owner of building Weight, the problem that cost is high.

In order to solve the problems referred to above, the technical solution used in the present invention is: this double-speed motor control method, uses double speed Motor control assembly realizes, and described double-speed motor controls device and includes control chamber, is provided with first and connects in described control chamber Tentaculum, the second catalyst, the 3rd catalyst and thermorelay, be provided with on the chamber door of described control chamber and be provided with automatic/hand Switching switch, stop button, low rate start button and the high-speed starting button of shelves；Described switching switch, stop button, low speed open Dynamic button and high-speed starting button, described switching switch, stop button, low rate start button, high-speed starting button, the second contact Device, the 3rd catalyst, the first catalyst and thermorelay series connection form slow control circuit；Described first catalyst and described low Speed start button parallel connection forms low speed latching circuit；Described first catalyst is connected with described second catalyst and is formed the first series connection Circuit, described first catalyst is connected with described 3rd catalyst and is formed the second series circuit, described first series circuit and institute State the second series circuit parallel connection and form parallel circuit；Described switching switch, stop button, high-speed starting button, low rate start are pressed Button and described parallel circuit formed high speed manual control circuit, described second catalyst and described 3rd catalyst series connection and with institute State high-speed starting button parallel connection and form high speed latching circuit；Described switching switch, relay, low rate start button and parallel circuit Series connection forms High-Speed Automatic control circuit.

In technique scheme, more specifically scheme is it may also is that described switching switch, the first catalyst and low speed are transported Turn display lamp series connection and form low-speed running indicating circuit, described 3rd catalyst and the display lamp series connection formation fortune at a high speed that runs up Turn indicating circuit；Described low-speed running display lamp and the described display lamp that runs up are installed on the chamber door of described control chamber.

Owing to have employed technique scheme, the present invention compared with prior art, has the beneficial effect that in daily life In work, if there is slight smog, slowspeed machine can be started and smog is discharged, if smokescope has reached fire mark Standard, fire-fighting system starts high-speed electric expreess locomotive by relay, smokescope is preferably minimized within the shortest time.

Accompanying drawing explanation

Fig. 1 is the front view of the control chamber of the present invention.

Fig. 2 is the principle schematic of the present invention.

Detailed description of the invention

The invention will be further described with embodiment below in conjunction with the accompanying drawings:

Double-speed motor control method shown in Fig. 1 and Fig. 2, uses double-speed motor to control device and realizes, and double-speed motor controls dress Put and include control chamber, the first catalyst KM1, the second catalyst KM2, the 3rd catalyst KM3 and heat are installed in control chamber and continue Electrical equipment KH, is provided with switching switch SA, stop button SB3, the low rate start being provided with automatic/hand shelves on the chamber door of control chamber Button SB1 and high-speed starting button SB2；Switching switch SA, stop button SB3, low rate start button SB1 and high-speed starting button SB2, switching switch SA, stop button SB3, low rate start button SB1, high-speed starting button SB2, the second catalyst KM2, the 3rd Catalyst KM3, the first catalyst KM1 and thermorelay KH series connection form slow control circuit；First catalyst KM1 and low speed open Dynamic button SB1 parallel connection forms low speed latching circuit；First catalyst KM1 and the second catalyst KM2 series connection forms the first series electrical Road, the first catalyst KM1 and the 3rd catalyst KM3 series connection forms the second series circuit, the first series circuit and the second series electrical Road parallel connection forms parallel circuit；Switching switch SA, stop button SB3, high-speed starting button SB2, low rate start button SB1 and also Connection circuit formed high speed manual control circuit, the second catalyst KM2 and the 3rd catalyst KM3 series connection and with high-speed starting button SB2 parallel connection forms high speed latching circuit；Switching switch SA, relay K A, low rate start button SB1 and parallel circuit in series are formed High-Speed Automatic control circuit.Switching switch SA, the first catalyst KM1 and low-speed running display lamp HR1 series connection forms low-speed running Indicating circuit, the 3rd catalyst KM3 and the display lamp HR2 series connection formation that runs up run up indicating circuit.Low-speed running refers to Show that lamp HR1 and the display lamp HR2 that runs up is installed on the chamber door of described control chamber.

Under normal circumstances, switching switch SA being got to automatic transmission, circuit is standby, occurs when there being slight smog Time, switching switch SA to be got to manual, presses low rate start button SB1, slow control circuit obtains electric, and motor is at low speed Driving exhaust blower to be discharged by slight smog, after this slight smog is discharged, switching switch SA is got to automatic transmission, circuit recovers to treat Life state；When there being fire to occur, fire-fighting system controls the adhesive of relay K A, and High-Speed Automatic control circuit obtains electric, and motor is at a high speed Operating drives exhaust blower to run, and is discharged rapidly by smog.
