Abstract
The utility model provides a hydraulic oil cooling device, quick -witted incasement hydraulic oil heat exchanger lead to the compressor respectively through two pipelines and take the condenser of fan and reservoir to constitute two refrigerant cycle pipelines after the expansion valve communicates the hydraulic oil heat exchanger, the hydraulic oil heat exchanger is established two hydraulic oil input tubes and is connected respectively to merge behind the oil pump and establish the input port, adds in the oil pump rear end of wherein hydraulic oil input tube and establishes air -cooled cooler, the hydraulic oil heat exchanger is established in addition and is established the delivery outlet after two hydraulic oil output pipes merge. The hydraulic oil cooling device who from this constitutes, during the use, but accessible endless liquid refrigerant makes it to drop to the oily warm of adapted to operation with the heat that has the hydraulic oil of uniform temperature through hot exchanged mode, and hot switching speed is fast, the cooling is effectual.
Description
Technical field
This utility model is related to a kind of device to hydraulic oil cooling, specifically 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, can make
Oil temperature is become to gradually rise, oil temperature, when reaching more than 60 DEG C, is easily caused stability and the work energy of hydraulic pressure cylinder apparatus operation
Power declines, and also can thus lead to hydraulic oil to go bad and cannot use, meanwhile, the high oil temperature of excessive time-out, or even also can make
Become hydraulic system leakage and fault, cause unsafe contingency, convenient in time and be reliably that hydraulic oil drops for this
Temperature is the Reliable guarantee of hydraulic system safe operation.
Content of the invention
The purpose of this utility model is to solve the above problems, and provides a kind of hydraulic oil cooling device, have small volume and
After hydraulic system configuration uses, can timely and conveniently be lowered the temperature for hydraulic oil.
This utility model includes compressor and oil pump, and the technical scheme being adopted is: in cabinet, hydraulic oil heat exchanger is led to
Cross two pipelines and lead to compressor respectively and connect hydraulic oil heat exchanger with after the condenser with blower fan and reservoir through expansion valve
Constitute two refrigerant circulation pipe；Hydraulic oil heat exchanger sets to merge after two hydraulic oil input pipes connect oil pump respectively and sets input
Mouthful, the oil pump rear end of hydraulic oil input pipe wherein adds air-cooled cooler；It is defeated that hydraulic oil heat exchanger separately sets two hydraulic oil
Outlet pipe sets delivery outlet after merging.
This utility model has following advantageous effect: by technique scheme, the package unit being constituted is used with hydraulic pressure
After oil pipe line leads to, can high temperature be inputted to the circulation heat exchange through cold-producing medium is rapidly achieved reduction oil temperature with oil circulation in good time
Effect, thus solve that present hydraulic oil exists produces excessive high temperature and affects the difficult problem normally run, favourable hydraulic pressure
The stable safe operation of oil cylinder and improve production efficiency.

Specific embodiment
Fig. 1, shown in 2: in cabinet 1, hydraulic oil heat exchanger 2 is passed through two pipelines 3 and is led to compressor 4 respectively and with blower fan
Connect hydraulic oil heat exchanger 2 through expansion valve 7 after condenser 5 and reservoir 6 and constitute 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, hydraulic oil input pipe wherein
8 oil pump 10 rear end adds air-cooled cooler 9；Hydraulic oil heat exchanger 2 separately sets after two hydraulic oil outlet tubes 12 merge and sets output
Mouth 13.
During enforcement, several condensation fans can be distributed on the panel of punch-out equipment side and lower the temperature to cocurrent flow type condenser 7, opposite side
The radiator window with display screen for the setting.
Operation logic of the present utility model is as follows: the high temperature hydraulic oil after doing work is pumped into through liquid by oil pump 10 from input port 11
Force feed input pipe 8 enters hydraulic oil heat exchanger 2；Wherein one hydraulic oil input pipe 8 enters hydraulic oil heat exchanger through air-cooled cooler 9
2, the high temperature hydraulic oil being entered carries out cold and hot exchange with the liquid refrigerant of low-temp low-pressure, and its liquid refrigerant absorbs heat energy
Afterwards, that is, the gaseous state being evaporated to low-temp low-pressure enters the gaseous state of compressor 4 boil down to High Temperature High Pressure, then through the condenser 5 with blower fan
The liquid that cooling becomes High Temperature High Pressure enters reservoir 6, then by expanding the liquid vapour mixing that 7 throttling expansions are low-temp low-pressure
Thing input hydraulic pressure oil exchanger 2 carries out cold and hot exchange again, and such iterative cycles run and reach technology mesh of the present utility model
's.
