Description
Technical field
The utility model relates to the technical field that equipment controls automatically, espespecially a kind of cutting fluid automatic governing control circuit.
Background technology
Cutting fluid is the requisite running stores of mechanical processing industry, different according to the requirement of lathe, all use with cutting fluid allotment water, the allotment of cutting fluid is all generally manual operation, ratio for cutting fluid and water controls to be difficult to control, and artificial allotment there will be phenomenon not in time, affects the use of lathe.
Summary of the invention
A kind of cutting fluid automatic governing of the utility model control circuit, utilizes time relay control contactor, magnetic valve, realizes automatic fixed proportion allotment cutting fluid, improves the object of automaticity.
To achieve these goals, technical solution of the present utility model is: a kind of cutting fluid automatic governing control circuit is made up of breaker, the first contactor, the second contactor, the first water pump, the second water pump, the first miniature relay, the second miniature relay, very first time relay, second time relay, the first magnetic valve, the second magnetic valve, normal open switch, emergency stop switch, liquid level gauge; Civil power access breaker, draw wire by breaker and access the first contactor, the second contactor respectively, connecing the first water pump by the first contactor, the second contactor connects the second water pump; By the coils connected in series of liquid level gauge lower-limit point with the first miniature relay, liquid level gauge upper change point, with the coils connected in series of the second miniature relay, then accesses breaker live wire, zero line by after two series circuit parallel connections; After normal open switch is in parallel with the normal battle of the first miniature relay, upper end access breaker live wire, the parallel circuit upper end that lower end forms with the coil of very first time relay, the coil of second time relay is connected, termination breaker zero line under the parallel circuit of the coil of very first time relay, the coil composition of second time relay; By the coil of the first contactor, the first magnetic valve parallel connection, series circuit is formed again with normal battle of very first time relay, by the coil of the second contactor, the second magnetic valve parallel connection, series circuit is formed again with normal battle of second time relay, termination breaker live wire is gone up in two series circuit parallel connections afterwards, normally closed point, the emergency stop switch of lower end and the second miniature relay are connected, by termination breaker zero line under emergency stop switch; Be a kind of cutting fluid automatic governing control circuit.
Described breaker is ic65n c40A;
The first described contactor, the second contactor model are CJX2-08-01;
The first described water pump, the second water pump are identical ground pump;
The first described miniature relay, the second miniature relay rated voltage are all 220V;
The first described magnetic valve, the second magnetic valve are all 21A5TK45 Electromagneitc valve for fluid;
The time delay disconnect type time relay of described very first time relay, second time relay to be model be DH48S-2Z, reference time delay is 0.01S-999.9H;
First must set the delay time of very first time relay, second time relay according to the volume of mixed liquor bucket and the ratio of requirement allotment before using; Such as the first water pump water receiving source, second water pump connects cutting fluid original liquid box, require that allotment ratio is that water is than cutting fluid stoste 3:1, so the time of very first time relay will be set as 3 times of the time of second time relay setting the delay time of second time relay according to the volume of mixed liquor bucket.In use procedure, if mixed liquor liquid level reaches the liquid level gauge lowest limit, so system can start automatically; If time relay setting error, liquid level reaches the liquid level gauge upper limit, and system can stop automatically, can not cause roof fall, waste cutting fluid.
The utility model beneficial effect is: adopt cutting fluid automatic governing control circuit, improve the automaticity of equipment, save manpower, avoids artificial allotment problem not in time; Ensure that allotment ratio, can not cause and allocate rare, feeding-up problem, the waste problem simultaneously roof fall can also being avoided to cause.
