The forced self-cooling hydraulic coupling transmission cooling system adopts full automatic closed-loop structure, and in work period of the hydraulic coupling, by self-regulation of the cooling system, the cooling amount is matched with the attrition power of the coupling, to make the hydraulic coupling in an optimum working temperature all long: 67+-3 degree C. The device has advantages of small accommodation area, convenience in movement, and simple operation, and is especially suitable for the work situation without cooling water, and the efficiency of the hydraulic coupling can be enhanced.
Description
Technical field
The utility model relates to hydraulic coupler transmission device, is specifically related to a kind of pressure self-cooled hydraulic coupler transmission device.
Background technique
Continuous expansion along with the speed-regulating hydraulic coupler transmission device application, the user is more and more higher to the requirement of speed-regulating hydraulic coupler transmission device, existing variable speed fluid coupling device just can not adapt to some specific occasions, specific environment technical requirements, do not satisfy user's special requirement because there is following defective:
(1) floor space is big.Variable speed fluid coupling need be used cooler, and the big need of cooler volume have bigger placement space, can't satisfy the requirement of field construction to equipment installation, transportation etc.
When (2) the variable speed fluid coupling speed governing was worked, different rotating speed wasted power differences created a difference the temperature of working oil.Variable speed fluid coupling is worked under best effort oil temperature, influence coupling efficiency.
Summary of the invention
The utility model provides a kind of pressure self-cooled hydraulic coupler transmission device, adopts the integrated modular design and by regulating the supply of freezing mixture, has solved the problem that existing speed-regulating hydraulic coupler transmission device exists.The utility model is specifically taked following measure: the top, case lid top that Working oil cooler, forced cooling device is installed on hydraulic coupler transmission device; The chilling temperature feedback control system is installed in the casing side of hydraulic coupler transmission device; The hydraulic coupler transmission device control system is installed in the casing another side of hydraulic coupler transmission device; The hydraulic coupler transmission device fuel tank is placed on the below.
Described fuel tank is adorned a temperature transmitter away from the position of inlet port.
The chilling temperature feedback control system of described belt variable function regulator is linked and packed with cooling control valve and pressure cooling system.
Advantage of the present utility model is: owing to adopt the integrated modular design, little, the conveniently moving of volume is particularly useful for the field, moves frequent construction occasion; Owing to adopt and regulate the cooling system of cooling medium consumption at random, solved amount of cooling water and fluid coupling loss power thermal balance problem, make fluid coupling improve efficient.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 forces self-cooled hydraulic coupler transmission device plan view;
Fig. 2 forces self-cooled hydraulic coupler transmission device rear view;
Fig. 3 forces self-cooled hydraulic coupler transmission device right elevation.
Mark among the figure: Working oil cooler 1, hydraulic coupler transmission device 2, forced cooling device 3, chilling temperature feedback control system 4, cooling control valve 5, hydraulic coupler transmission device control system 6, fuel tank 7, inlet port 8, temperature transmitter 9.
Embodiment
As shown in Figure 1, 2, 3, this device adopts the integrated modular design.Working oil cooler 1, forced cooling device 3 are installed on the top, case lid top of hydraulic coupler transmission device 2; Chilling temperature feedback control system 4 is installed in the casing side of hydraulic coupler transmission device 2, and hydraulic coupler transmission device control system 6 is installed in the another side of hydraulic coupler transmission device 2 casings.It is become can satisfy the working machine requirement, what need not other supporting facility just can satisfy the unit module that working machine requires, and compact structure is saved the space, conveniently moving.
The variable speed fluid coupling optimum working temperature is 67 ℃.The oil temperature is low excessively, and oil viscosity increases, and liquid friction loss increases, and the working efficiency of coupler is descended; The oil temperature is too high, makes the bearing working worsening condition, and rubber seal is easy to aging even damages.Fluid coupling certainly exists slippage in operation process, thereby power loss is arranged, and changes into the heat of working oil, causes the oil temperature to rise.Can reach the purpose of balance fluid coupling loss power by the flow of automatic adjusting cooling medium.
As shown in Figure 2, force the self-cooled hydraulic coupler transmission device to adopt full-automatic closed loop work.Adorn a temperature transmitter 9 at transmission device fuel tank 7 away from the position of inlet port 8, cooling control system receives temperature transmitter 9 output 4mA-20mA signals.No matter how the fluid coupling load changes, and when the fluid coupling wasted power was big, when promptly oily temperature was higher, cooling unit strengthened cooling medium consumption automatically, and oil temperature is reduced; Otherwise, reduce cooling medium consumption, oil temperature is raise.Because the hysteresis quality of coupler is installed variable function regulator (PID) in chilling temperature feedback control system 4, be connected with cooling control valve 5; Utilize variable function regulator (PID), the amount of cooling water of cooling system and the loss power of fluid coupling are balanced each other, guarantee that coupler is in 67 ± 3 ℃ of best effort temperature all the time.Thereby solved variable speed fluid coupling loss power difference under different operating modes, or its working oil temperature is changed thereupon, to such an extent as to influence the difficult problem of coupling efficiency because of ambient temperature changes.
