The concrete principle of implementing:
A. leave standstill: promptly brake fluid is placed in the position that is not subjected to external action, leaves standstill the regular hour, make the most of air that contains in the brake fluid, separate naturally, thoroughly eliminate for next step and contain the ready of air in brake fluid.When brake fluid when oil drum 78 is extracted into fluid infusion fuel tank 76, contain more composition of air in the brake fluid.So must leave standstill a period of time in fluid infusion fuel tank 76 flows in the filling fuel tank 30 again.Flowing therebetween is to utilize one to be in than the pipe of low level and to realize.First filter, 74, the first filters 74 are housed on the pipe to be needed regularly to clean.The brake fluid that first electric oil pump 40 is extracted into from filling fuel tank 30 is exactly the purer brake fluid through leaving standstill.
B. calm: utilize the physical phenomenon of object stress deformation, when promptly object was subjected to power, as long as this power is no more than the regime of elastic deformation of object self, after this power disappeared, object will return to stressed preceding shape.In brake fluid and Air mixing body, when being under pressure: the deformation coefficient of air is just bigger.And brake fluid is because the characteristics of itself, the coefficient of its distortion is very little, be almost 0, when these mixtures are under pressure, when mixed liquor (calm jar 51) when tiny pipeline is flowed through one the container that becomes suddenly big, make that the change in flow of brake fluid and gas is different, the gas of the pressurized formation air pocket that will expand suddenly, will merge the bigger bubble of formation between the bubble simultaneously, utilize calm jar 51 particular design collection bubble also to emit automatically, just be easy to the tiny air separation that contains in the brake fluid is come out, guaranteed the pure of filling brake fluid, make the braking ability of automobile reach good effect.
Including the brake fluid charging machine equipment of eliminating the device of bubble in the brake fluid adopts gear pump to pressurize to brake fluid, after the overflow valve voltage stabilizing, enter calm jar, brake fluid utilizes the special construction of air expansion principle and calm jar to eliminate tiny gas in calm jar, then through the control of magnetic valve, enter motor vehicle brake fluid through filling gun and store oil can, because the brakes UNICOM of this oil can and automobile, so brake fluid has also just entered the whole brakes of automobile, on the brake hub of 4 wheels of automobile, the exhaust outlet that a brake cylinder is respectively arranged, when opening exhaust outlet, air in brake fluid and the automotive system is discharged simultaneously, utilize one to be inserted in plastic pipe transparent on the exhaust outlet, the brake fluid of discharging is collected in the returnable bottle, observe the brake fluid that flows in the plastic tube simultaneously, when the brake fluid that flows is represented the air emptying of brake system of car during in pellucidity, at this moment the operative employee can pull out transparent plastic tube, closes exhaust outlet, presses the stop button of charging machine.
When the stop button of brake fluid charging machine equipment is pressed, the output of the valve closing brake fluid of equipment pipeline, open brake fluid simultaneously and store the valve that the oil can liquid level is adjusted, carry out the liquid level adjustment that brake fluid stores oil can, rely on length-adjustable filler pipe on the filling muzzle, utilize the filling pressure that remains in the pipeline, make pipeline produce siphonage, when siphon is drawn onto the pasta in the oil can and the mouth of pipe of annotating when flushing, siphon disappears automatically, and whole filling process finishes.Siphon specific implementation method:
The first step, in the charging line system of charging machine, establish 2 oil circuit valve switch (normally closed often opens), when brake fluid charging (normally closed opening, Chang Kaiguan closes), valve return to normal (its duty is seen asphalt principle figure) when filling finishes.
Second step, in order to guarantee the generation of siphonage, must make the difference in height of a filler and oil return fuel tank.So we are placed on charging machine below the operating platform, the liquid level difference that makes it both has 1000mm approximately.
The 3rd step, in order to adjust the metal line that stores oil can automatically, need stretch into brake fluid in one of design on the filling gun and store the filler pipe that can regulate length in the oil can.
