Abstract
The invention provides a hydraulic oil cooling device which is characterized in that a hydraulic oil heat exchanger in a case communicates with compressors, condensers with fans, and liquid storage devices through two pipelines respectively, and then expansion valves communicate with the hydraulic oil heat exchanger to form two refrigerant circulating pipelines; the hydraulic oil heat exchanger is provided with two hydraulic oil input pipes; the two hydraulic oil input pipes are respectively connected with oil pumps and then are combined to form an input port; an air cooling cooler is additionally arranged at the rear end of the oil pump of one hydraulic oil input pipe; the hydraulic oil heat exchanger is additionally provided with two hydraulic oil output pipes; and the two hydraulic oil output pipes are combined to form an output port. With the adoption of the scheme, when the hydraulic oil cooling device is in use, through heat exchange between a circuiting liquid-state refrigerant and hydraulic oil at certain temperature, the hydraulic oil can be cooled to a temperature adaptable to working, the rate of heat exchange is high, and the cooling effect is good.
Description
Technical field
The present invention relates to a kind of device to hydraulic oil cooling, a kind of hydraulic oil cooling device.
Background technology
The suitable temperature of hydraulic cylinder oil is 35～55 DEG C, during hydraulic cylinder works, due to reasons such as compressions, oil temperature can be caused to gradually rise, oil temperature is once reach more than 60 DEG C, it is easily caused stability and ability to work decline that hydraulic cylinder equipment runs, also can thus cause hydraulic oil rotten and cannot use, simultaneously, the excessively high oil temperature of time-out, the most also can cause hydraulic system leakage and fault, cause unsafe contingency, be the most conveniently and reliably for hydraulic oil cooling the Reliable guarantee of hydraulic system safe operation for this.
Summary of the invention
It is an object of the invention to solve the problems referred to above, it is provided that a kind of hydraulic oil cooling device, have that volume is little and after hydraulic system configuration uses, can lower the temperature for hydraulic oil timely and conveniently.
The present invention includes compressor and oil pump, and the technical scheme used is: in cabinet, hydraulic oil heat exchanger connect hydraulic oil heat exchanger two refrigerant circulation pipe of composition through expansion valve after leading to the condenser of compressor and band blower fan and reservoir respectively by two pipelines；Hydraulic oil heat exchanger sets to merge after two hydraulic oil input pipes connect oil pump respectively and sets input port, and the oil pump rear end of hydraulic oil input pipe wherein adds air-cooled cooler；Hydraulic oil heat exchanger separately sets after two hydraulic oil outlet tubes merge and sets delivery outlet.
The present invention has following advantageous effect: pass through technique scheme, after the package unit constituted and hydraulic oil pipeline lead to, can extremely by high temperature with oil circulation input in good time, through cold-producing medium cycling hot exchange be rapidly achieved reduce oil temperature effect, thus solve producing excessive high temperature and affecting a properly functioning difficult problem of present hydraulic oil existence, the stable safe operation of favourable hydraulic jack and raising production efficiency.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is present configuration schematic diagram.
Fig. 2 is schematic diagram after the present invention assembles.
In figure: 1, cabinet, 2, hydraulic oil exchanger, 3, pipeline, 4, compressor, 5, the condenser of band blower fan, 6, reservoir, 7, expansion valve, 8, hydraulic oil input pipe, 9, air-cooled cooler, 10, oil pump, 11, input port, 12, hydraulic oil outlet tube, 13, delivery outlet.
Detailed description of the invention
Fig. 1, shown in 2: in cabinet 1, hydraulic oil heat exchanger 2 connects hydraulic oil heat exchanger 2 through expansion valve 7 after leading to the condenser 5 of compressor 4 and band blower fan and reservoir 6 respectively by two pipelines 3 and constitutes two refrigerant circulation pipe 3；Hydraulic oil heat exchanger 2 sets to merge after two hydraulic oil input pipes 8 connect oil pump 10 respectively and sets input port 11, and oil pump 10 rear end of hydraulic oil input pipe 8 wherein adds air-cooled cooler 9；Hydraulic oil heat exchanger 2 separately sets after two hydraulic oil outlet tubes 12 merge and sets delivery outlet 13.
During enforcement, can be distributed several condensation fan and lower the temperature to cocurrent flow type condenser 7 on the panel of punch-out equipment side, opposite side arranges the radiator window of band display screen.
The operation logic of the present invention is as follows: the high-temperature liquid force feed after acting is pumped into from input port 11 and enters hydraulic oil heat exchanger 2 through hydraulic oil input pipe 8 by oil pump 10；Wherein a hydraulic oil input pipe 8 enters hydraulic oil heat exchanger 2 through air-cooled cooler 9, the high-temperature liquid force feed entered carries out cold and hot exchange with the liquid refrigerant of low-temp low-pressure, after its liquid refrigerant absorbs heat energy, the gaseous state being i.e. evaporated to low-temp low-pressure enters the gaseous state of compressor 4 boil down to High Temperature High Pressure, condenser 5 cooling of band blower fan becomes the liquid entrance reservoir 6 of High Temperature High Pressure again, again carry out cold and hot exchange by expanding the liquid vapour mixture input hydraulic pressure oil exchanger 2 that 7 throttling expansions are low-temp low-pressure again, so iterative cycles runs the technical purpose i.e. reaching the present invention.
