As shown in Figure 1 and Figure 2, the pressure medium of tested hydraulic prop can change along with constantly suppressing of the pump housing, at first setting the pressure P segmentation of measured medium, is under-voltage condition when pressure P is in (0-P1), with the emitting red light two diode indicator lamp 6-2 indication of flicker; When pressure P is in (P1-P2) normal condition, with the green LED indicator lamp 6-3 indication of Chang Liang; Pressure P is an overvoltage condition when being in (P2-∞), with the yellow light-emitting diode indicator lamp 6-1 indication of flicker.
The principle of pressure alarm circuit:
As shown in Figure 2: the on/off of power switch 8 (K3) control entire circuit, when K3 was closed, other components and parts could operate as normal.
The normal range of operation of at first setting electro connecting pressure gauge 9 is put for the number of [P1-P2], during hydraulic prop work, when the pressure P of measured medium when (0-P), K switch 1 closure, K2 disconnects, and the level of the input A of three or eight decoder U1 is a high level, and B, C end level is a low level; The output Y1 of three or eight decoder U1 is a low level simultaneously, and all the other outputs are high level; Red colored lamp 6-2 this moment (D2) lights and glimmers, and shows that the pressure medium P of hydraulic prop is low, should improve.
When the pressure P of measured medium when [P1-P2], K switch 1 disconnects, K2 disconnects.Input A, the B of three or eight decoder U1, the level of C are low level at this moment; The output Y0 of three or eight decoder U1 is a low level simultaneously, and all the other outputs are high level; Green light 6-3 this moment (D3) lights, and sees the green indicating lamp of Chang Liang, and the pressure medium P that shows hydraulic prop is in normal range (NR).
When the pressure P of measured medium when (P2-∞), K switch 1 disconnects the K2 closure.This moment three or eight decoders U! The level of input A, C be low level, the level of B is a high level; The output Y2 of three or eight decoders is a low level simultaneously, and all the other outputs are high level; Amber light 6-1 this moment (D1) lights and glimmers, and shows the pressure medium P height of hydraulic prop, should reduce.
Because electro connecting pressure gauge 9 structures own can not cause the closed simultaneously situation of K switch 1, K2.As this situation appears, will can not light any indicator lamp 6.Should check whether electro connecting pressure gauge 9 damages this moment.
