Abstract
The utility model relates to a constant temperature device for a hydraulic oil tank, belongs to the field of manufacturing machinery. The technical problem to be solved by the utility model is to provide a device which can keep the temperature of hydraulic system. An oil return pipe is connected on the hydraulic oil tank. A cooler is serially connected on the oil return pipe. A heater and an electric contact temperature gauge are installed on the hydraulic oil tank. The heater and the cooler can be connected with the electric contact temperature gauge via a programmable controller. The electric contact temperature gauge can control the heater or cooler to switch on or off via the programmable controller, in order to keep the hydraulic oil temperature in the hydraulic oil tank in a normal working range and ensure the stability of the hydraulic system.
Description
Technical field
The utility model relates to a kind of hydraulic oil container constant temperature device, particularly mechanical manufacturing field.
Background technique
Nowadays, hydraulic system is widely used in the various machinery of every profession and trade, and the too high meeting of the hydraulic oil temperature in the hydraulic system causes in-oil cylinder Sealing to damage, cause that easily oil cylinder leaks, the oil temperature is crossed when hanging down, and it is big that viscosity becomes, cause the hydraulic parts stroke not in place, workpiece can not normally send the position.
The model utility content
The technical problems to be solved in the utility model provides a kind of hydraulic oil container constant temperature device.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of hydraulic oil container constant temperature device, be connected to return tube on the hydraulic oil container, its innovative point is: be in series with cooler on described return tube, on the described hydraulic oil container casing heater and electric contact thermometer are housed, described heater is connected with electric contact thermometer by programmable controller with cooler.
Advantage of the present utility model is: the oil temperature of electric contact thermometer monitoring hydraulic system, by heater and cooler the temperature of hydraulic oil is controlled at stable operation interval, and guaranteed the stability of hydraulic system.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Figure is the schematic representation of hydraulic oil container constant temperature device of the present utility model.
Embodiment
As shown in the figure, be connected to return tube 2 on the hydraulic oil container 1, be in series with cooler 3 on described return tube 2, on described hydraulic oil container 1 casing heater 4 and electric contact thermometer 5 be housed, described heater 4 is connected with electric contact thermometer 5 by programmable controller 6 with cooler 3.
On described electric contact thermometer 5, set normal temperature, when the hydraulic fluid temperature in the hydraulic oil container 1 exceeds the temperature of setting, electric contact thermometer 5 transmits signal by programmable controller 6 and gives cooler 3, cooler 3 unlatching work, hydraulic fluid temperature reduces, and after hydraulic fluid temperature dropped to normal temperature, electric contact thermometer 5 transmission signal were given programmable controller 6, cooler 3 quits work, and keeps hydraulic fluid temperature.Spend when low when hydraulic oil temperature, by the 4 unlatching work of programmable controller 6 control heaters, hydraulic fluid temperature rises, and guarantees the normal operation of hydraulic system.
Claims (1)
1. hydraulic oil container constant temperature device, be connected to return tube (2) on the hydraulic oil container (1), it is characterized in that: on described return tube (2), be in series with cooler (3), heater (4) and electric contact thermometer (5) are housed on described hydraulic oil container (1) casing, and described heater (4) is connected with electric contact thermometer (5) by programmable controller (6) with cooler (3).
