Abstract

본 발명은 유압기의 유압유 온도자동 조절장치에 관한 것이다. 일반적으로 유압장치는 각종기계에 널리 사용되고 있으나 이와 같은 유압기에는 유압유의 온도자동 조절장치가 없기 때문에 겨울철과 같이 외부의 온도가 한냉할 시는 유압관이 동파됨으느 물론 유압유의 점도가 높아 작동이 원활하지 못한 폐단이 있고 여름철과 같이 외부기온이 매우 높을때는 유압유가 말라서 감량되거나 점도가 너무 낮아서 압력이 감퇴되는 폐단이 있었던 것이다.The present invention relates to a hydraulic oil temperature automatic control device of the oil press. In general, the hydraulic system is widely used in various machines, but since there is no automatic control device for the temperature of the hydraulic oil, the hydraulic tube is freezes when the outside temperature is cold like winter, and the viscosity of the hydraulic oil is high, so the operation is smooth. When there is a dead end and the outside temperature is very high, such as in summer, there is a closed end where the hydraulic oil dries up or the pressure decreases because the viscosity is too low.

본 발명은 이상의 문제점을 해결하고자 발명한 것으로 이의 발명요지는 오일탱크(1)의 내부에는 히터(15)를 설치하고 오일탱크(1)의 외부에는 냉각팬쿨러(12)를 설치하여 겨울철과 같이 외부기온이 매우 한냉하여 유압유의 온도가 18℃이하일 시는 히터(15)가 자동으로 ON되면서 유압유를 가열하여 적정온도가 되게하고 여름철과 같이 외부기온이 매우 더워서 유압유가 마르거나 유압유의 점도가 너무 낮아 유압기의 힘이 약할때는 센서의 감지에 의해 냉각팬쿨러(12)가 자동으로 ON되면서 유압유의 마름현상이나 유압유의 점도 하강현상을 방지하므로서 유압기의 정상적인 가동을 가능케하며 유압유의 온도가 60℃에 달하면 이때에는 감지센서에 의해 경보기가 자동으로 ON 되면서 비상신호를 발할 수 있게 한 것이다.The present invention has been invented to solve the above problems, the present invention is to install a heater (15) inside the oil tank (1) and a cooling fan cooler (12) is installed outside the oil tank (1) as in winter When the outside temperature is very cold and the temperature of the hydraulic oil is 18 ℃ or less, the heater 15 turns on automatically and heats the hydraulic oil to a proper temperature.The external temperature is very hot like the summer season, so the hydraulic oil dries or the viscosity of the hydraulic oil is too high. When the pressure of the oil pressure is low, the cooling fan cooler 12 is automatically turned on by the detection of the sensor, preventing the oil from drying out or the viscosity of the oil falling, thus enabling the normal operation of the oil pressure. In this case, the alarm is automatically turned on by the sensor so that an emergency signal can be generated.
