The utility model discloses loose between oil inlet and the oil -out of import 1 parallelly connected check valve as the bypass valve at hydraulic oil, it can reduce the fluid resistance, protects hydraulic oil radiator, as the check valve of bypass valve to open the pressure differential setting value less, with regard to like this guaranteed the radiator not can owing to low temperature hydraulic oil in the twinkling of an eye pressure too big and lead to the weak position fracture of radiator.
Description
Technical field
The utility model relates to a kind of radiator, and the utility model especially relates to a kind of pressure release oil radiator.
Background technology
When hydraulic work system, the energy of the consumption such as the pressure loss of the volumetric loss of Hydraulic Elements, mechanical loss and pipeline and fluid friction loss is almost all converted into heat. These heats can cause system oil liquid temp to raise. If 80 DEG C of oil liquid temperatures too high (>), hydraulic oil will sharply change because of oxidized performance, and the sealing property of each Hydraulic Elements also can decline, and will have a strong impact on the normal work of hydraulic system. The operating temperature of the engineering mechanical hydraulic oils such as general loading machine is 30 ~ 80 DEG C. When working oil temperature exceedes after 60 DEG C, the service life of fluid will be influenced. More severe when the working condition of machine, system caloric value is larger; Especially in the time of summer operation, some regional environment temperature is too high, and oil temperature rises faster, makes like this machinery operation decrease in efficiency, and the fault rate of Hydraulic Elements increases, and causes the machine can not normal operation when serious. So, must take to force cooling measure, fall apart to control oil temperature by hydraulic oil, make it to meet system works requirement.
Because hydraulic oil cold scattering fluid flow is but larger, and inside, hydraulic oil diffusing road is provided with many fins, and the fluid of flowing through is produced to larger flow resistance. In the time that temperature is higher, the pressure loss that hydraulic oil is loose is relatively little, but environment temperature is when lower, and hydraulic oil viscosity becomes greatly with the reduction of temperature, thereby flow resistance is larger, the loose corresponding rising of pressure of bearing of oil. Now, no matter start vehicle, still carry out operation, the compression shock of hydraulic system is all larger, easily causes that radiator is at the weaker link in the positions such as oil inlet pipe, radiating core, grease chamber or commissure cracking.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of pressure release oil radiator of reliable, long service life is provided.
The technical scheme providing according to the utility model, described pressure release oil radiator, it comprises upper cover, upper cover interface, low head, low head interface, support plate, heat radiation core body, upper check valve interface, check valve, connecting hose and lower check valve interface; On upper cover, be fixed with upper cover interface, on low head, be fixed with low head interface, between upper cover and low head, be fixed with heat radiation core body, the left and right sides at heat radiation core body is fixed with support plate, check valve interface on being fixed with on upper cover, on upper check valve interface, be fixed with check valve, on check valve, be fixed with connecting hose, the other end access low head of connecting hose.
Be fixed with upper cover interface in the left part of upper cover, be fixed with low head interface in the right part of low head.
On upper cover, offer temperature control interface.
On low head, be fixed with swivel nut.
The utility model falls apart between the oil-in of device and oil-out, 1 check valve in parallel is as by-passing valve at hydraulic oil, and it can reduce oil liquid resistance, protection hydraulic oil radiator; Starting differential pressure setting value as the check valve of by-passing valve is less, has so just ensured that radiator can not cause because low temperature hydraulic oil instantaneous pressure is excessive the weak part of radiator to ftracture.

Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
This pressure release oil radiator, it comprises upper cover 1, upper cover interface 2, low head 3, low head interface 4, support plate 5, heat radiation core body 6, upper check valve interface 7, check valve 8, connecting hose 9 and lower check valve interface 10; On upper cover 1, be fixed with upper cover interface 2, on low head 3, be fixed with low head interface 4, between upper cover 1 and low head 3, be fixed with heat radiation core body 6, the left and right sides at heat radiation core body 6 is fixed with support plate 5, on upper cover 1, be fixed with check valve interface 7, on upper check valve interface 7, be fixed with check valve 8, on check valve 8, be fixed with connecting hose 9, the other end access low head 3 of connecting hose 9.
Be fixed with upper cover interface 2 in the left part of upper cover 1, be fixed with low head interface 4 in the right part of low head 3.
On upper cover 1, offer temperature control interface 11.
On low head 3, be fixed with swivel nut 12.
The utility model falls apart into 1 check valve 8 in parallel between the oil-in of device and oil-out as by-passing valve at hydraulic oil; when oil-feed and oil return pressure reduction reach while setting up numerical value; check valve 8 as by-passing valve is opened; part fluid directly passes through connecting hose 9 oil returns by grease chamber; the heat radiation core body 6 of no longer flowing through carries out cooling; reduce oil liquid resistance with this, protection hydraulic oil radiator. Starting differential pressure as the check valve 8 of by-passing valve is set as 0.3Mpa, has so just ensured that radiator can not cause because low temperature hydraulic oil instantaneous pressure is excessive the weak part cracking of radiator.
The utility model has increased temperature detect switch (TDS) at temperature control interface 11 places, hydraulic oil radiator adopts fan to carry out cooling to hydraulic oil, in the time that oil temperature is low, temperature detect switch (TDS) cuts out, and fan does not carry out work, shorten like this " warm-up period ", in the time that hydraulic system load strengthens, fan need add Wind Volume, in the time that hydraulic system load reduces, wind flow reduces thereupon, realizes the energy-conservation and Based Intelligent Control of variable-flow.
