Abstract
A temperature control circuit for a main machine of a lubrication oil station comprises a lubrication oil station main machine circuit and is characterized by further comprising a delayed temperature control circuit. The delayed temperature control circuit is in parallel connection with an alternating current relay KM of the lubrication oil station main machine circuit and comprises a lamp L, a time relay KT and a temperature relay T. The lamp L is in parallel connection with the time relay KT, then the lamp L is in series connection with the temperature relay T, and a normally closed contact KT1 is in series connection with an alternating current contactor KM of the lubrication oil station main machine circuit. The temperature control circuit for the main machine of the lubrication oil station is simple in structure and convenient to use. When oil temperature rises abnormally, the temperature control circuit can give out alarm immediately and supplies response time for workers. Therefore, the main machine is prevented from being shut down with materials in, and good economic benefit and social benefit are brought.
Description
Technical field
The utility model relates to a kind of Lubricating-oil Station main frame temperature control circuit.
Background technique
Lubricating-oil Station in use the phenomenon that main frame trips can occur if the too high situation of oil temperature occurs.Owing to there is not foresight cannot take protective measure, often the band material is shut down during the main frame tripping operation.Just the situation that has band material start when restarting, the equipment that influences is safe in utilization and increase unnecessary energy consumption.
The model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of and can overcome above-mentioned defective, can intuitively report to the police when oily temperature rise, and avoid with the Lubricating-oil Station main frame temperature control circuit of expecting shutdown.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of Lubricating-oil Station main frame temperature control circuit, comprise the Lubricating-oil Station host circuit, it is characterized in that: also comprise the time-delay temperature-control circuit, the AC relay KM of time-delay temperature-control circuit and Lubricating-oil Station host circuit is connected in parallel; Described time-delay temperature-control circuit comprises bulb L, time relay KT and temperature relay T, be connected in series with temperature relay T after bulb L and the time relay KT parallel connection, the normally-closed contact KT1 of time relay KT connects with the A.C. contactor KM of Lubricating-oil Station host circuit.
When the oil temperature surpasses set point of temperature, the time-delay temperature-control circuit is connected the luminous warning of bulb L, the time relay KT work that picks up counting, timing finish the back by the power supply that its normally-closed contact KT closes the AC relay KM of Lubricating-oil Station host circuit, close the power supply of Lubricating-oil Station host circuit and finish the main frame tripping operation.After the luminous warning of bulb L, the material that the staff handles Lubricating-oil Station if having time in the time period of time relay KT time-delay closing host power supply avoids the band material to shut down.
The beneficial effect that the utility model had is: simple in structure, easy to use, when the oily temperature abnormality of appearance raise, the very first time reported to the police, and provided the processing time to the staff, avoided the material web material to shut down, and had good economic benefit and social benefit.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams;
Among the figure: 1, time-delay temperature-control circuit; 2, Lubricating-oil Station host circuit.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, a kind of Lubricating-oil Station main frame temperature control circuit comprises Lubricating-oil Station host circuit 2, also comprises time-delay temperature-control circuit 1, and time-delay temperature-control circuit 1 is connected in parallel with the AC relay KM of Lubricating-oil Station host circuit 2; Described time-delay temperature-control circuit 1 comprises bulb L, time relay KT and temperature relay T, be connected in series with temperature relay T after bulb L and the time relay KT parallel connection, the normally-closed contact KT1 of time relay KT connects with the A.C. contactor KM of Lubricating-oil Station host circuit 2.
After the oil temperature surpasses set point of temperature, temperature relay T closure, bulb L and time relay KT get, the luminous warning of bulb L, time relay KT begins timely work, close the power supply of the AC relay KM of Lubricating-oil Station host circuit 2 after timing finishes by its normally-closed contact KT, AC relay KM dead electricity its contact KM disconnects, and closes the power supply of Lubricating-oil Station host circuit 2 and finishes the main frame tripping operation.After the luminous warning of bulb L, the material that the staff handles Lubricating-oil Station if having time in the time period of time relay KT time-delay closing host power supply avoids the band material to shut down.
