Abstract
The utility model discloses a fuel feeding device used for turbochargers, which comprises an oil inlet pipe connected with a lubricating oil inlet of the turbocharger, wherein a pipe line of the oil inlet pipe is connected with an accumulator used for storing lubricating oil and keep the lubricating oil in certain pressure; a pipe line between the accumulator and a lubricating oil supply system of an engine is connected in series with a first check valve which can be opened towards the lubricating oil inlet direction of the turbocharger. During the process that a lubricating system of the engine supplies the lubricating oil to the turbocharger, the accumulator stores the lubricating oil with certain pressure, as a result, when a lubricating oil supply system of an internal combustion engine provides deficient lubricating oil or does not provide the lubricating oil for the turbocharger, the accumulator can continuously supply the lubricating oil to an exhaust gas turbocharger which temporarily and continuously rotates at high rotational speed for some time so as to play the role of cooling and lubricating a turbine shaft so that the service life of the turbocharger is extended.
Description
Technical field
The utility model relates to a kind of oil supplying device that improves the turbocharger lubrication effect.
Background technique
Turbosupercharger utilizes the waste gas of motor to improve the power of motor, because it has saved the energy greatly, so obtained to use widely in technical field of engines, as shown in Figure 1, turbosupercharger 1 includes the turbine shaft 4 with the turbine rotation, the rotating speed of turbine and turbine shaft 4 up to 100,000 rev/mins about, so the designer is provided with the oil supply system of lubricated turbine shaft 4 on the turbosupercharging body, it comprises lubricant oil filler opening 2 and lubricant oil oil outlet 3, and lubricant oil filler opening 2 is connected with the lubrication system of motor with return tube 31 by oil inlet pipe 21 with lubricant oil oil outlet 3.In engine overload or when shutting down suddenly; the lubricant oil fuel feeding that the lubricating oil supply system of internal-combustion engine provides to turbosupercharger is not enough or lubricant oil no longer is provided; so the turbine shaft 4 of high speed rotating can damage because of the disappearance of lubricant oil; thereby damage whole turbosupercharger; delay production on the one hand, increased the user cost of motor on the other hand greatly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of oil supplying device that is used for turbosupercharger that improves the turbocharger lubrication effect.
For achieving the above object, the technical solution of the utility model is: the oil supplying device that is used for turbosupercharger, comprise the oil inlet pipe that is connected with pressurized machine lubricant oil filler opening, be connected with on the pipeline of described oil inlet pipe and be used to store lubricant oil and keep lubricant oil to have the accumulator of certain pressure, be serially connected with first one-way valve that to open to pressurized machine lubricant oil filler opening direction on the pipeline between the lubrication oil supply system of described accumulator and motor.
As a kind of improvement, also be provided with second one-way valve that can open to pressurized machine lubricant oil filler opening direction between described accumulator and the pressurized machine lubricant oil filler opening, the described oil supplying device that is used for turbosupercharger also comprises one by pipeline and first one-way valve that be connected in series mutually, accumulator and the parallel connection of second one-way valve and the one-way valve that can open to pressurized machine lubricant oil filler opening direction.
Owing to adopt technique scheme, the oil supplying device that is used for turbosupercharger, comprise the oil inlet pipe that is connected with pressurized machine lubricant oil filler opening, be connected with on the pipeline of described oil inlet pipe and be used to store lubricant oil and keep lubricant oil to have the accumulator of certain pressure, be serially connected with first one-way valve that to open to pressurized machine lubricant oil filler opening direction on the pipeline between the lubrication oil supply system of described accumulator and motor; In the lubrication system of motor in the process of turbosupercharger fuel feeding, accumulator has been stored the lubricant oil with certain pressure, and the lubricant oil fuel feeding that provides to turbosupercharger when the lubricating oil supply system of internal-combustion engine is not enough or lubricant oil no longer is provided, continue exhaust-gas turbocharger supplying lubricating oil a period of time of being rotated further with high rotating speed to temporarily by accumulator, play the effect of cooling and lubricated turbine shaft, thus the working life of having improved turbosupercharger greatly.
Description of drawings
Accompanying drawing 1 is the structural representation of turbosupercharger.
Accompanying drawing 2 is schematic diagrams of the utility model embodiment.
Embodiment
As shown in Figure 2, be used for the oil supplying device of turbosupercharger, comprise the oil inlet pipe 21 that is connected with pressurized machine 1 lubricant oil filler opening 2, be connected with on the pipeline of described oil inlet pipe 21 and be used to store lubricant oil and keep lubricant oil to have the accumulator 5 of certain pressure.Be serially connected with first one-way valve 51 that to open to pressurized machine 1 lubricant oil filler opening 2 directions on the pipeline between the lubrication oil supply system of described accumulator 5 and motor.Also be provided with second one-way valve 52 that can open to pressurized machine 1 lubricant oil filler opening 2 directions between described accumulator 5 and the pressurized machine 1 lubricant oil filler opening 2, the described oil supplying device that is used for turbosupercharger also comprises one by pipeline 6 and first one-way valve 51 that be connected in series mutually, accumulator 5 and 52 parallel connections of second one-way valve and the one-way valve 61 that can open to pressurized machine 1 lubricant oil filler opening 2 directions.
Accumulator is parts commonly used in the hydraulic system, the 17-684 page or leaf of " mechanical design handbook " Volume Four that Chemical Industry Press publishes in January, 2002 has been done detailed description to its function and structure, and accumulator also is that the engineers and technicians in present technique field are known, do not repeat them here.
The effect of first one-way valve 51 is to prevent that accumulator pressure oil when the machine oil air pump inoperative of motor from pouring in down a chimney, the effect of second one-way valve 52 is when initial fuel feeding, the oil pump that guarantees motor is at first by pipeline 6 and open one-way valve 61 rapidly and provide lubricant oil to turbosupercharger, the temporary transient fuel feeding deficiency of lubricant oil improves reliability of the present utility model when avoiding engine start.
Its working principle is as follows:
During engine operation, the oil pump of motor is transported to the lube oil inlet pipe road of turbosupercharger with lubricant oil, by pipeline 6 and open one-way valve 61 rapidly the lubricant oil with certain pressure is provided to turbosupercharger; The oil pump of motor also provides the lubricant oil with certain pressure by the pipeline and first one-way valve 51 to accumulator 5 simultaneously, and when accumulator 5 stored lubricant oil reached certain pressure, second one-way valve 52 was also opened and provided lubricant oil to turbosupercharger.And the oil pressure of working as the oil pump of motor drops to after the certain pressure, and the one-way valve 61 and first one-way valve 51 are closed, and the lubricant oil with certain pressure in the accumulator 5 are opened second one-way valve 52, and provide lubricant oil to turbosupercharger; When the utility model fluctuates in engine speed, but the deficiency of make-up oil, and when stopping suddenly, also can be to the exhaust-gas turbocharger supplying lubricating oil a period of time that temporarily is rotated further with high rotating speed, play the effect of cooling and lubricated turbine shaft, thus the working life of having improved turbosupercharger greatly.
