Abstract
The utility model provides a hydraulic hybrid power oil temperature control device, and belongs to oil temperature control devices. An oil port of a hydraulic accumulator of the oil temperature device is connected with an A port of a two-position two-way reversing valve and an oil inlet of an electronic control overflow valve; a P port of the two-position two-way reversing valve is connected with an oil outlet of a heat radiator; an oil inlet of the heat radiator is connected with an oil outlet of a hydraulic pump motor; an oil suction port of the hydraulic pump motor and an oil outlet of the electronic control overflow valve are both connected with an oil tank; a temperature sensor is mounted on a pipeline between the hydraulic accumulator and the two-position two-way reversing valve; a signal output end of the temperature sensor is connected with a first signal input end of a controller; and a control signal input end of the electronic control overflow valve is connected with a second signal output end of the controller. The oil temperature control device has the advantages that when the oil temperature is too high, the hydraulic oil overflows back to the oil tank, and then a hybrid power system stops working, so that the work efficiency of the hydraulic hybrid power system is improved, the system safety is guaranteed, the reliability is high, and engineering is easy to achieve.
Description
Technical field
The utility model relates to a kind of oil-temperature control device, particularly a kind of hydraulic hybrid oil-temperature control device.
Background technique
Along with developing rapidly of industrial technology in the world wide, energy shortage and environmental pollution problem also are on the rise.The hydraulic hybrid technology is considered to one of effective scheme that solves energy crisis and environmental pollution problem.It is big that hydraulic hybrid has specific power, energy recovery efficiency advantages of higher, the kinetic energy of recovery and reuse vehicle braked effectively.The transformation of energy of high-power stream raises the oil temperature of hydraulic hybrid power system rapidly, and too high oil temperature influences the whole efficiency of hydraulic hybrid power system, the working life of reducing system.
The model utility content
The purpose of this utility model is to provide a kind of: the hydraulic hybrid oil-temperature control device solves hydraulic hybrid power system oil temperature too high problem easily.
The purpose of this utility model is achieved in that oily temperature device is made up of hydraulic accumulator, temperature transducer, controller, automatically controlled relief valve, fuel tank, hydraulic pump motor, radiator and 2/2-way selector valve;
The hydraulic accumulator hydraulic fluid port is connected with the A mouth of 2/2-way selector valve and the filler opening of automatically controlled relief valve, the P mouth of 2/2-way selector valve is connected with the oil outlet of radiator, the filler opening of radiator is connected with the oil outlet of hydraulic pump motor, and the inlet port of hydraulic pump motor all is connected with fuel tank with the oil outlet of automatically controlled relief valve; Temperature transducer is installed on the pipeline between hydraulic accumulator and the 2/2-way selector valve, the signal output part of temperature transducer is connected with first signal input part of controller, the control signal input end of 2/2-way selector valve is connected with first signal output part of controller, and the control signal input end of automatically controlled relief valve is connected with the secondary signal output terminal of controller.
Beneficial effect, owing to before having adopted such scheme, radiator to be installed in the hydraulic pump motor oil outlet, the hydraulic oil of mixed power system is dispelled the heat, temperature transducer detects hydraulic fluid temperature, and is sent in the controller and compares with the Maximum operating temperature of setting.When hydraulic fluid temperature was lower than Maximum operating temperature, controller control 2/2-way selector valve was open-minded, hydraulic hybrid power system work; When hydraulic fluid temperature was greater than or equal to Maximum operating temperature, controller transmitted control signal to automatically controlled relief valve, and hydraulic oil is overflowed in the fuel tank, controlled the 2/2-way selector valve simultaneously and closed, hydraulic hybrid power system work.
Hydraulic oil in the mixed power system is carried out radiating treatment, the monitors oil temperature, oil is warm when too high; mixed power system is not worked, and hydraulic oil overflows back fuel tank, protective system safety; solve hydraulic hybrid power system oil temperature too high problem easily, reached the purpose of this utility model.
The utility model has the advantages that: the hydraulic oil in the hydraulic hybrid power system is carried out radiating treatment, monitor hydraulic fluid temperature simultaneously.Oil is warm when too high, and hydraulic oil overflows back fuel tank, and mixed power system is not worked, and has improved the working efficiency of hydraulic hybrid power system, protective system safety.Have higher reliability with period control method and system architecture, and be easy to realize through engineering approaches.
