Description

l feeders 8, 8 formyro .j9 pulse cutters 9 memory hems, 10, .. ,, 10 elements AND And a block of feeders 12, The device works in the following way. The first generator I generates pulses that arrive at pulse counter 2. After recalculation of the set number of pulses, pulse counter 2 sends a pulse to command trigger 3, Command trigger 3 tilts from the state And the samdm causes the second generator 5 to apply power to the second generator 5 , alarm device 6 and supercharger unit 7. Supercharger

unit 7 creates pressure in the system and the feeders of unit 12 reciprocate, displacing a metered amount of lubricant to the friction units.

The signals from the sensors controlling the feeders 8, 8, ..., 8 are fed to the pulse shapers 9, 9,.,. , 9 "Shapers you, pulse pulses at., 10 only memory triggers 10 k in the case of full reciprocating movement of feeders. 10,.;., 10 Memory triggers U / when pulses are received from pulse formers 9 × 9, ... the set inputs are set to 1 and thus the inputs of the And 11 element receive positive voltages. If there is an AND 11 positive voltage on all the turns on its output, a negative voltage is obtained, which trips the command trigger 3 and memory triggers 10 10,.,., The initial state. In this case, the switch 4 is disconnected, the power units of the unit 7, the second generator 5 are switched off, and in the alarm unit 6 the Lubricant switches to Pause. The lubrication cycle repeats after the installed conversion of the pulse counters 2 from the generator 1. If at least one of the feeders of the block 12 does not reciprocate, then the corresponding control with the feeders

Invention Formula A device for automatic control and monitoring by the lubrication system, containing the first generator, the output of which, through a pulse counter, the boost pulse generator 9, 9, ..., 9 does not override the corresponding memory trigger, 1.0,. . . , 10 from O to F and the corresponding potential of the inputs of element 11 will have a low potential, which prevents it from getting a negative impulse at its output. When the time set on the second generator 5 has elapsed, this generator is triggered and will generate an alarm signal to the alarm unit. The use of the invention allows to expand the scope of application of the device in lubrication systems and eliminate the need to use several devices for angle and direction to the first input of the command trigger, the output of which through the switch is connected to the first input of the alarm unit, the input of the second generator and through the serially connected compressor block to the inputs sensors of control of feeders, the output of the second generator is connected to the second input of the signaling unit, characterized in that eneni device, it comprises zlementy And, pulse shapers, and triggers the memory whose outputs are connected via AND gate to the second input of the trigger command and the first inputs of the memory flip-flops to the second input of which is connected via a pulse shaper outputs a control feeders sensors.
