Abstract
Disclosed is an oil temperature automatic control device adopting an oil tank as the carrier, belonging to the construction crane oil temperature automatic control equipment. The utility model comprises a hydraulic oil radiator, a radiator oil return pipe, an oil tank oil return pipe, a temperature sensor and a hydraulic oil tank; the temperature sensor is connected to the lower part of the side wall of the hydraulic oil tank, the upper part of the hydraulic oil tank is connected with the hydraulic radiator through the oil tank oil return pipe and the lower part is connected with the radiator oil return pipe. The utility model has the advantages that the device strengthens the automatic detection to the temperature of the hydraulic system and realizes the automatic control to the temperature rise of the hydraulic system; the hydraulic oil tank is the biggest unit in storing hydraulic oil and transfer mechanism in the system, thereby if the hydraulic oil tank is taken as the carrier, the temperature rise conditions of the system can be objectively showed, the temperature of the hydraulic oil can be automatically controlled and the work intensity of the operator is reduced; the temperature of the hydraulic oil is scientifically defined, thus the protection of the system is strengthened.
Description
Technical field
The utility model relates to a kind of crane oil temperature automatic control device, and particularly a kind of is the oily temperature automatic control device of carrier with the fuel tank.
Background technique
Engineering machinery is with the media base of hydraulic oil as hydraulic system, hydraulic oil is the key factor that influences hydraulic system stability, temperature can raise during hydraulic working oil, temperature is too high, the physical property of hydraulic oil is changed, the stability of hydraulic system will be destroyed, thereby the work safety of whole engineering machinery can be threatened.
At present, the cool-down method that uses on the crane has two kinds: the one, thermometer is installed on hydraulic oil container, and observe the variation of oil temperature by operator oneself, find cooling if desired, open hydraulic oil radiator again, rely on operator's subjectivity and randomness fully; The 2nd, hydraulic oil radiator is just worked when system works begins, and causes the shortcoming of startability variation when low temp area is worked for hydraulic system.
Summary of the invention
The purpose of this utility model is to provide a kind of: what can detect automatically the temperature of hydraulic system, control be the oily temperature automatic control device of carrier with the fuel tank.
The purpose of this utility model is achieved in that and includes hydraulic oil radiator, radiator return line, tank drainback pipeline, temperature transducer and hydraulic oil container, below the sidewall of hydraulic oil container, be connected with temperature transducer, upper end at hydraulic oil container is connected with the hydraulic pressure radiator by the tank drainback pipe, is connected with the radiator return tube in the lower end of hydraulic pressure radiator.
Beneficial effect: owing to adopted such scheme, hydraulic system is when work, the hydraulic oil of systemic circulation is through the radiator return tube hydraulic oil radiator of flowing through, get back to hydraulic oil container through the tank drainback pipe again, the temperature transducer that is installed on the hydraulic oil container detects the interior hydraulic fluid temperature of hydraulic oil container constantly; When temperature was within normal range (NR), temperature transducer did not transmit signal, and hydraulic oil radiator is not worked; When the hydraulic fluid temperature in temperature transducer detects hydraulic oil container surpassed the normal range value of setting, temperature transducer sent instruction just for the hydraulic pressure oil radiator, and hydraulic oil radiator is started working, and lowers the temperature to hydraulic oil; In the time of in temperature drops to normal range (NR), temperature transducer stops to send instruction, and hydraulic oil radiator quits work.Can detect automatically the temperature of hydraulic system, control, reach the purpose of this utility model.Advantage: this device has been strengthened the automatic detection to the hydraulic system temperature; realized automatic control to the hydraulic system temperature rise; hydraulic oil container is the unit and the exchanging mechanism of storage hydraulic oil maximum in the system; with the hydraulic oil container is carrier; just more can objectively reflect the temperature rise situation of system, and control the temperature of hydraulic oil automatically, alleviate operator's labor intensity; hydraulic fluid temperature there be defining of science, thereby strengthened protection system.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Embodiment
Embodiment 1: include hydraulic oil radiator 1, radiator return tube 2, tank drainback pipe 3, temperature transducer 4 and hydraulic oil container 5, below the sidewall of hydraulic oil container 5, be connected with temperature transducer 4, upper end at hydraulic oil container 5 is connected with hydraulic oil radiator 1 by tank drainback pipe 3, is connected with radiator return tube 2 in the lower end of hydraulic oil radiator 1.Hydraulic system is in when work, and the hydraulic oil of systemic circulation is got back to hydraulic oil container 5 through return line 3 again through return tube 2 hydraulic oil radiator 1 of flowing through.At this moment, be installed in the hydraulic fluid temperature that the temperature transducer 4 on the hydraulic oil container 5 detects in the hydraulic oil container 5 constantly.
When temperature was within normal range (NR), temperature transducer 4 did not transmit signal, and therefore, hydraulic oil radiator 1 is not worked.When the hydraulic fluid temperature in the temperature transducer 4 detection hydraulic oil containers 5 surpassed the normal range value of setting, temperature transducer 4 sent instruction just for hydraulic pressure oil radiator 1, and hydraulic oil radiator 1 is started working, thereby lowers the temperature to hydraulic oil.In the time of in temperature drops to normal range (NR), temperature transducer 4 stops to send instruction, and hydraulic oil radiator 1 quits work.
Claims (1)
1. one kind is the oily temperature automatic control device of carrier with the fuel tank, it is characterized in that: include hydraulic oil radiator, radiator return line, tank drainback pipeline, temperature transducer and hydraulic oil container, below the sidewall of hydraulic oil container, be connected with temperature transducer, upper end at hydraulic oil container is connected with the hydraulic pressure radiator by the tank drainback pipe, is connected with the radiator return tube in the lower end of hydraulic pressure radiator.
