Abstract
The utility model discloses a diesel engine low-pressure oil way air separator, which aims to solve the problems of pollution, waste, and time and labor consuming caused by using a manual oil pump for manual air exhaust when a diesel engine has air resistance during use. The diesel engine low-pressure oil way air separator comprises a top cover, a cup, an oil inlet pipe, an oil outlet pipe, an air exhaust pipe and a changeover switch, wherein the top cover is airtightly screwed to the upper side of the cup, the oil inlet pipe penetrating through an oil inlet of the top cover is positioned inside the cup, the oil outlet pipe penetrating through an oil conveying opening of the top cover is positioned inside the cup, and the changeover switch and the air exhaust pipe are arranged on the top cover and communicated with each other by the aid of an air conveying pipe. Besides, an air exhaust opening and an emergency air exhaust pipe is arranged below the top cover; and an air control valve is arranged at the lower end of the air exhaust opening and connected with a floater. The diesel engine low-pressure oil way air separator has the advantages of eradicating pollution and waste, and being more time-saving and labor-saving.
Description
Technical field
The utility model relates to a kind of diesel engine air separator, particularly a kind of diesel engine low pressure oil circuit air separator.
Background technique
At present, most diesel engine in the course of the work, if it is not smooth that the fuel pump fuel feeding of motor takes place, cause the low pressure oil circuit to produce vapour lock, shake will appear in motor, the breath phenomenon stagnates, cause the motor cisco unity malfunction, particularly when the winter temperature rapid drawdown of cold, use the vehicle of fuel oil label deficiency to stop, the back use hand oil pump of fixing a breakdown carries out manual exhaust to oil circuit, the diesel oil that is being mingled with air in exhaust process will be discharged from bleeder screw, caused great pollution and waste, and also more time-consuming, the effort of manual exhaust.
Summary of the invention
The purpose of this utility model be use that hand oil pump carries out that manual exhaust pollutes in order to solve diesel engine and in use air-resistance phenomenon to take place, the problem of waste and time-consuming, effort and a kind of diesel engine low pressure oil circuit air separator of providing.
The utility model is made up of top cover, cup, oil inlet pipe, oil outlet tube, outlet pipe and throw over switch, the airtight top that is screwed in cup of top cover wherein, oil inlet pipe passes the top cover filler opening and is positioned at cup, oil outlet tube passes top cover oil transportation mouth and is positioned at cup, throw over switch and outlet pipe be located at top cover above, be connected by pneumatic tube between throw over switch and the outlet pipe, be provided with relief opening and emergent outlet pipe below the top cover, the lower end of relief opening is provided with air control valve, air control valve is connected with float, and relief opening and emergent outlet pipe all are communicated with outlet pipe by throw over switch.
In order to observe the exhaust situation of fuel oil in the cup preferably, cup is made by transparent material, and the below of cup is provided with a sewage draining exit.
In order also to use the utility model preferably in the winter time, in cup, be provided with heater, heater is an electric heater, the used electric energy of electric heater is imported by the storage battery on the car, and is provided with the control that temperature detect switch (TDS) heats on circuit.
Working principle of the present utility model is: the utility model is installed between diesel oil fine cleaner and the high-pressure service pump, and fuel oil is input in the cup through oil inlet pipe by fine cleaner, and fuel oil enters high-pressure service pump through oil outlet tube after reaching volume.When entering air in the low pressure oil circuit, after the fuel oil that is being mingled with air entered cup, air separated automatically with fuel oil, and the pasta in the cup descends, float moves down air control valve and opens relief opening, discharges the passage that relief opening, throw over switch and the outlet pipe of air below the top cover of cup top forms.Along with the air in the cup reduces, pasta rises, and moves air control valve on the float and closes relief opening, makes the integral body that forms sealing in the cup, and fuel oil is passed by by oil outlet tube through this and entered into the high-pressure service pump supply engine.When the air control valve in the cup breaks down, also can use emergent outlet pipe to carry out exhaust, be transformed into the gear that emergent outlet pipe is communicated with outlet pipe to throw over switch and just can finish manual exhaust, the possibility of having avoided fuel oil to leak this moment.
The beneficial effects of the utility model: when producing a small amount of gas in the low pressure oil circuit, need not to stagnate motor and get final product automatic vent, if there is a large amount of gas to enter oil circuit, also can in airtight cup, carry out the separation of oil gas, the gas and the fuel oil of discharging directly flow back into fuel tank, stopped to pollute and waste, and relatively save time, laborsaving.
