Abstract
The utility model discloses an oil temperature control device for a hydraulic system, which comprises a two-position two-way magnetic valve, a hydraulic oil throttleer, a cooler, a temperature sensor, and an oil tank. The P-A passage of the two-position two-way magnetic valve is connected between an oil pump and a reversing solenoid valve in a hydraulic system, and the B end of the two-position two-way magnetic valve is connected to the hydraulic oil throttleer and then the oil tank; the cooler is connected between the reversing solenoid valve in the hydraulic system and the oil tank; and the temperature sensor is arranged in the oil tank. After adopting the oil temperature control device, when hydraulic oil needs to be heated, the hydraulic oil flows through the hydraulic oil throttleer, and the oil temperature rises because the pipeline section in the hydraulic oil throttleer decreases. For the above process, in the first step, heat generated by the self-running of the oil pump is utilized to heat the hydraulic oil, and in the second step, the heat generated when the hydraulic oil flows through a small hole is utilized to heat the hydraulic oil. The whole oil temperature control device has simple realization process and low manufacturing cost.
Description
Technical field
The utility model relates to a kind of oil-temperature control device of hydraulic system.
Background technology
For guaranteeing the reliability of hydraulic work system, hydraulic system must be provided with oil-temperature control device.Hydraulic system is made up of oil pump, fuel tank, reversing solenoid valve, hydraulic cylinder, refrigeratory.Hydraulic oil gets into the hydraulic cylinder acting from fuel tank through the oil pump supercharging and heats up, and after the subcooler cooling, gets back to fuel tank again, so circulation.
Wherein, be provided with temperature sensor in the fuel tank, the hydraulic oil well heater.Temperature sensor is provided with high and low two temperature value reference mark, and when hydraulic fluid temperature was lower than the low point temperature value, refrigeratory stopped operating, and the hydraulic oil well heater is started working hydraulic oil is heated.When temperature was between two temperature values, refrigeratory and hydraulic oil well heater were not all worked, when temperature is higher than height point temperature value, and refrigeratory running heat radiation, the hydraulic oil well heater stops heating.Guarantee that thus hydraulic oil is in the rational operating temperature range.
Above-mentioned hydraulic oil heater structure is complicated, and mounting process is had relatively high expectations, if hydraulic system is used for explosion-proof environment, then need be used explosion-proof type hydraulic oil well heater, and this kind hydraulic pressure well heater price is very expensive, and the manufacturing cost of equipment is higher.
The utility model content
The purpose of the utility model is to provide a kind of oil-temperature control device of hydraulic system, this oil-temperature control device novel structure, and manufacturing cost is lower.
The utility model to achieve these goals, the technical solution of employing is:
The oil-temperature control device of hydraulic system; Comprise 2/2-way solenoid valve, hydraulic oil flow controller, refrigeratory, temperature sensor and fuel tank; Said 2/2-way solenoid valve P-A path is connected between the oil pump and reversing solenoid valve of hydraulic system; Insert fuel tank behind the B termination hydraulic oil flow controller, said refrigeratory is connected between the reversing solenoid valve and fuel tank of hydraulic system, and temperature sensor is arranged in the fuel tank.
Further, said refrigeratory is an air cooled chiller.
The beneficial effect of the utility model:
The oil-temperature control device of this kind hydraulic system; When hydraulic oil need heat, make hydraulic oil flow through the hydraulic oil flow controller, because the pipeline cross section diminishes in the hydraulic oil flow controller; The oil temperature rise; The heat of self heated for hydraulic oil when the above process first step had been utilized the oil pump running, and the heating phenomenon had realized the heating to hydraulic oil when second step was flowed through aperture through hydraulic oil.In addition,, avoid when hydraulic oil heat refrigeratory that hydraulic oil is lowered the temperature, make the hydraulic fluid temperature rising faster, more efficient through circuit control.Whole oil-temperature control device implementation procedure is simple, cheap for manufacturing cost.
Description of drawings
Fig. 1 is the synoptic diagram of the oil-temperature control device of hydraulic system in hydraulic system applications.
Embodiment
In conjunction with Fig. 1 the utility model is elaborated:
The oil-temperature control device of hydraulic system; Comprise 2/2-way solenoid valve 1, hydraulic oil flow controller 2, refrigeratory 3, temperature sensor 4 and fuel tank 5; Said 2/2-way solenoid valve P-A path is connected between the oil pump 6 and reversing solenoid valve 7 of hydraulic system, and fuel tank 5 is inserted in B termination hydraulic oil flow controller 2 backs.Said refrigeratory 3 is connected between the reversing solenoid valve 7 and fuel tank 5 of hydraulic system, and temperature sensor 4 is arranged in the fuel tank 5.
More preferably: said refrigeratory 3 is an air cooled chiller.
The use of oil-temperature control device is following: temperature sensor 4 is provided with high and low two temperature value reference mark; When hydraulic fluid temperature is lower than the low point temperature value; The fan of refrigeratory 3 stops operating, and 2/2-way solenoid valve 1 is in the P-B path, and hydraulic oil gets into fuel tank 5 through hydraulic oil flow controller 2.At this moment, oil pump 6 is in operating condition, and hydraulic oil can generate heat during through oil pump 6, and when hydraulic oil was flowed through hydraulic oil flow controller 2, because the pipeline cross section diminishes, oily temperature obviously raise once more.Can control temperature rise speed through regulating hydraulic oil flow controller 2 latus rectums.
When temperature was between high and low two temperature values, 2/2-way solenoid valve 1 was in the logical position of P-A, and hydraulic oil gets into hydraulic cylinder 8 actings through reversing solenoid valve 7.This moment, refrigeratory 3 was not worked, and hydraulic oil is got back to fuel tank 5.When temperature further raise and be higher than height point temperature value, 2/2-way solenoid valve 1 was in the logical position of P-A, and hydraulic oil is through reversing solenoid valve 7 entering hydraulic cylinder actings, the heat radiation of refrigeratory 3 fan runnings.Guarantee that thus hydraulic oil is in the rational operating temperature range.
The oil-temperature control device of this kind hydraulic system, when hydraulic oil need heat, the heat of self heated for hydraulic oil when the first step had been utilized oil pump 6 runnings, and the heating phenomenon had realized the heating to hydraulic oil when second step was flowed through aperture through hydraulic oil.In addition, through circuit control, avoid 3 pairs of hydraulic oil coolings of refrigeratory when hydraulic oil heats, it is faster, more efficient that hydraulic fluid temperature is raise.Whole oil-temperature control device implementation procedure is simple, cheap for manufacturing cost.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technician in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
