Abstract
The invention relates to a fan operation detecting device which comprises a fan, a motor, a fan pulley, a fan impeller and a triangle belt. A detecting retaining block is arranged on the fan pulley, and a proximity switch is arranged on the lateral side of the detecting retaining block and is connected with a PLC (programmable logic controller) input point arranged outside the fan. The detecting retaining block is semi-circular. The fan operation detecting device is low in cost, simple in programming and convenient to mount.
Description
Technical field:
The present invention relates to a kind of blower fan apparatus, especially relate to a kind of fan operation testing fixture.
Background technique:
On heating plant, circulating fan plays a part very important in the uniformity to furnace temperature, in case blower fan outlet fault; If can't detect, the uniformity of furnace temperature can not get ensureing, also can cause very serious consequence to the performance quality of the workpiece in the stove; More existing detecting methods detect and corresponding counting module as increasing encoder, like this; Cost price is high, programming trouble very.
Summary of the invention:
Technical problem to be solved by this invention provides the simple fan operation testing fixture of the low programming of a kind of cost.
In order to solve the problems of the technologies described above; The present invention realizes through following technological scheme: this fan operation testing fixture; Comprise blower fan, motor, blower fan belt pulley, draught fan impeller and v belt; Said blower fan belt pulley is provided with the detection block, and detection block side is provided with near the switch PLC input point outside with being arranged on blower fan and is connected.
Detect for ease, further, said detection block semicircular in shape.
Compared with prior art, usefulness of the present invention is: this fan operation testing fixture is with low cost, and programming is simple, and is easy for installation.
Description of drawings:
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is structural representation of the present invention.
Among the figure: 1, blower fan; 2, motor; 3, blower fan belt pulley; 4, draught fan impeller; 5, v belt; 6, detect block; 7, near switch; 8, PLC input point.
Embodiment:
Describe the present invention below in conjunction with accompanying drawing and embodiment:
A kind of fan operation testing fixture shown in Figure 1; Comprise blower fan 1, motor 2, blower fan belt pulley 3, draught fan impeller 4 and v belt 5; Said blower fan belt pulley 3 is provided with semicircular detection block 6, and detection block 6 sides are provided with near the switch 7 PLC input point 8 outside with being arranged on blower fan and are connected.
Particularly, when motor 2 in when operation, also synchronous operation of draught fan impeller 4; Detect also synchronous operation of block 6, can feed back to signal of holding and closing of PLC near switch 7, through this signal of opening and closing; Coding in the program of PLC, under the normal condition, the signal of opening and closing can be gathered; When 5 fractures of the v belt of blower fan 1 or blower fan belt pulley 3 skid, will be in the state that opens or closes near the signal of switch 7, and then the program of writing a time-delay just can detect draught fan impeller 4 and whether moving always.
This fan operation testing fixture is with low cost, and programming is simple, and is easy for installation.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technological scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Claims (2)
1. fan operation testing fixture; Comprise blower fan (1), motor (2), blower fan belt pulley (3), draught fan impeller (4) and v belt (5); It is characterized in that: said blower fan belt pulley (3) is provided with and detects block (6), and detection block (6) side is provided with near switch (7) the PLC input point (8) outside with being arranged on blower fan and is connected.
