Background technique
At present in Forklift Industry, the mechanical type hydraulic oil radiator that the radiating mode of fork truck hydraulic oil mostly is the hydraulic system natural heat dissipation or with engine radiator, is made of one,, along with the fork truck tonnage is larger, by the hydraulic oil container natural heat dissipation, can not meet heat radiation requirement to hydraulic oil.As shown in Figure 1, be the structural representation of the mechanical type hydraulic oil radiation system of former and engine radiator one.the filler opening of hydraulic oil container 1 is connected with First Transition joint 2, First Transition joint 2 is connected with the second transit joint 4 by the first high-pressure rubber pipe 3, the second transit joint 4 is arranged on the filler opening of hydraulic-pressure pump 5, the 3rd transit joint 6 is installed on the oil outlet of hydraulic-pressure pump 5, the 3rd transit joint 6 is connected with the 4th transit joint 8 by the second high-pressure rubber pipe 7, the return opening of hydraulic oil container 1 is connected with the 6th transit joint 20, the 6th transit joint 20 is connected with the 5th transit joint 19 by third high moulding pipe 18, the 5th transit joint 19, the 4th transit joint 8 all is connected with water radiator Integral hydraulic oil loose 9.And the mechanical type hydraulic oil radiator that is made of one with engine radiator is due to the heat diffusion area that takies engine radiator, also can impact engine radiating, when ambient temperature is higher, cause easily that the engine water radiator is overheated or hydraulic oil is overheated, make engine radiating and hydraulic oil heat radiation can not reach good balance.
Summary of the invention
The technical problems to be solved in the utility model is: the mechanical type hydraulic oil radiator that is made of one with engine radiator is due to the heat diffusion area that takies engine radiator, can impact engine radiating, when ambient temperature is higher, cause easily that the engine water radiator is overheated or hydraulic oil is overheated, make engine radiating and hydraulic oil heat radiation can not reach good balance.
in order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of temperature controlled fork truck hydraulic oil cooling system, comprise hydraulic oil container, the inlet port of hydraulic oil container is connected with the First Transition joint, the First Transition joint is connected with the second transit joint by the first high-pressure rubber pipe, the second transit joint is located on the filler opening of hydraulic-pressure pump, the oil outlet of hydraulic-pressure pump is provided with the 3rd transit joint, the 3rd transit joint is connected with the 4th transit joint by the second high-pressure rubber pipe, the return opening of hydraulic oil container is connected with the 6th transit joint, the 6th transit joint connects by third high moulding Guan Yudi five transit joints, it is characterized in that, the 5th transit joint, the 4th transit joint all is connected with independent hydraulically controlled oil is loose, the loose temperature detect switch (TDS) that is provided with of independent hydraulically controlled oil, temperature detect switch (TDS) is connected with relay by the 3rd wire harness, relay is connected with motor-driven fan by the first wire harness, relay is connected with storage battery by the second wire harness.
The utility model can meet hydraulic oil heat radiation requirement, has independent hydraulic oil radiator, do not take the heat diffusion area of engine radiator, make engine radiating and hydraulic oil heat radiation get a promotion simultaneously, when oil temperature was not high, by motor-driven fan, not worked on hydraulic oil is loose, only depended on loose naturally cooling of hydraulic oil, make hydraulic oil temperature faster be elevated to suitable operating temperature, prevent that low temperature viscosity is excessive.When oil temperature over 70 degrees centigrade, temperature detect switch (TDS) is opened, and opens the motor-driven fan of hydraulic oil on loose by relay and dispels the heat, good heat dissipation effect, improved the working life of hydraulic system and the working efficiency of fork truck, and the hydraulic oil of installing separately loosely checks, maintenance is all more convenient.
Description of drawings
Fig. 1 is former and the structural representation of the mechanical type hydraulic of engine radiator one oil radiation system;
Fig. 2 is a kind of structural representation of temperature controlled fork truck hydraulic oil cooling system.
Embodiment
, for the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The utility model is a kind of temperature controlled fork truck hydraulic oil cooling system, as shown in Figure 2, is a kind of structural representation of temperature controlled fork truck hydraulic oil cooling system.First Transition joint 2 is installed on hydraulic oil container 1 inlet port, First Transition joint 2 couples together by the second transit joint 4 of installing on the first high-pressure rubber pipe 3 and hydraulic-pressure pump 5 filler openings, the 3rd transit joint 6 of installing on hydraulic-pressure pump 5 oil outlets is connected by the 4th transit joint 8 of installing on loose 10 filler openings of the second high-pressure rubber pipe 7 and independent hydraulically controlled oil, and independent hydraulically controlled oil loose 10 exports the 5th transit joint 19 installed on hydraulic fluid ports and is connected by the 6th transit joint 20 of installing on third high moulding pipe 18 and hydraulic oil container 1 return opening.Temperature detect switch (TDS) 17 is arranged on independent hydraulically controlled oil loose 10, temperature detect switch (TDS) 17 is connected with relay 15 by the 3rd wire harness 16, relay 15 is connected with motor-driven fan 11 by the first wire harness 12, and relay 15 also is connected with storage battery 14 by the second wire harness 13.
When work, the hydraulic oil of heat is extracted out by hydraulic-pressure pump 5 from hydraulic oil container 1, then flows into independent hydraulically controlled oil and falls apart 10, then from loose 10 outlets of independent hydraulically controlled oil, get back to hydraulic oil container 1.When hydraulic oil temperature surpassed 70 degrees centigrade, temperature detect switch (TDS) 17 was opened, and motor-driven fan 11 is supplied with in relay 15 power taking from storage battery 14, made it start to rotate, for hydraulic oil dispels the heat.
