Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The automatic oil supplementing and exhausting device for the diesel filter element device of the rail car as shown in fig. 1 to 3 comprises a primary filtering oil filter 1 and a secondary filtering oil filter 3, wherein one end of the primary filtering oil filter is connected with an oil tank, the other end of the primary filtering oil filter is connected with an inlet of an oil pump 2, an outlet of the oil pump 2 is connected with one end of the secondary filtering oil filter 3, the other end of the secondary filtering oil filter 3 is connected with an oil inlet of an engine through an oil pipe 6, when the engine is not started, the oil inlet of the engine is in a closed state, air and oil cannot enter, the oil pipe 6 is connected with an exhaust valve 5, and the exhaust valve 5 exhausts air. And a sensor 4 is arranged on the oil pipe 6 close to the engine and used for detecting whether the pipeline is full of diesel oil or not. The oil pump 2 is bolted through a pipe.
The exhaust valve 5 is an essential auxiliary element in a pipeline system, and the principle of the exhaust valve is that a floating buoy lever and the like are used for controlling the action of a pneumatic membrane in a cylinder, so that the opening and closing of an exhaust port of a valve body are controlled. Under high pressure (below 1 MPa), no matter the multi-section water column and air column are alternated, the pressure and non-pressure gas can be discharged at high speed, and a large amount of air accumulated in the pipe or a small amount of air accumulated at the higher part of the pipeline is discharged into the atmosphere.
The sensor 4 is a pressure sensor, and a semiconductor piezoelectric impedance diffusion pressure sensor is a pressure sensor in which a semiconductor deformation pressure is formed on a sheet surface, and a piezoelectric impedance effect is generated by deforming the sheet by an external force (pressure), so that a change in impedance is converted into an electric signal. When the pressure signal acts on the sensor, the pressure sensor converts the pressure signal into an electric signal, the electric signal is amplified by the differential amplifier and the output amplifier, and finally the electric signal is converted into a 4-20mA standard current output signal which is in linear corresponding relation with the liquid level pressure of the measured medium (liquid) through V/A voltage current. Sensor 4 power supply: the 24VDC outputs 4-20mA two-wire system, and the zero adjustable range is as follows: ± 5% F.S, range: -100kPa to 0 to 60MPa load characteristic: the load maintains constant current output within 0-600 omega (24 VDC power supply).
The sensor 4 is connected with the controller through signals, the electric signals are converted into digital signals under control, a pressure set value is arranged on the controller, and the KF coil is powered on/powered off when the pressure reaches the set value.
The pressure set value that sensor 4 detected is used for, 1, pressure reaches a definite value in the pipeline and can discharge the air completely, 2, sensor 4 detects the oil pump of closing when pressure reaches the set value, avoids the oil pump to last the operation to lead to pipeline and equipment damage that pipeline pressure too big brought, is a protection measure.
The power supply of the automatic oil supplementing and exhausting device of the diesel filter element of the rail car is DC 24V.
The oil pump 2 is started and diesel oil is piped through the primary filtering oil filter 1 and the secondary filtering oil filter 3 to the exhaust valve 5 and the sensor 4. At the moment, air is contained in the pipeline, the pipeline pressure is low, the oil pump 2 is operated all the time, the pipeline is pressurized, the air is discharged from the exhaust valve 5 under the pressure operation, and the pressure in the pipeline is increased along with the discharge of the air. When the air in the pipeline is exhausted, no pressure is reduced, the oil pump 2 continues to operate, the pressure in the pipeline continuously increases, and when the sensor 4 detects that the pressure reaches a set value, a signal is given, and the oil pump 2 stops operating.
The working process is as follows, the filter element is replaced, the oil pump 2 is started after the bolt connection and the sealing at each part are checked and fastened, the oil tank is filled with the primary filtering oil filter 1 through the pipeline in the flow direction, the oil pump pressurizes the oil to enter the secondary filtering oil filter 3, the air in the filter element and the pipeline is extruded by the diesel oil to move forwards, and the air passes through the primary filtering oil filter 1 and the secondary filtering oil filter 3 and is discharged out of the pipeline through the exhaust valve 5; and the sensor 4 is used for detecting whether the pipeline is filled with diesel oil or not.
The circuit working principle is as follows, the start button SB1 is pressed, the KA coil is electrified and attracted, the oil pump coil is opened and closed, and forms a self-locking circuit with the start button SB1, the oil pump is started, and the indicator light (green) is on. The diesel oil passes through the pipeline and flows to the engine, detects the diesel oil when the KF oil circuit and is full of the pipeline, and the KF oil circuit detects the sensing disconnection, and oil pump bring to rest, pilot lamp (red) are bright, and pilot lamp (green) go out.
The stop button SB2 is a manual stop button, and the stop button SB2 stops the operation of the oil pump when pressed. When the sensor 4 detects that the diesel oil is full of the pipeline, the power supply of the oil pump 2 is cut off, and the oil pump 2 stops running.
The points to be finally explained are: first, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may be a mechanical connection or an electrical connection, or a communication between two elements, and may be a direct connection, and "upper," "lower," "left," and "right" are only used to indicate a relative positional relationship, and when the absolute position of the object to be described is changed, the relative positional relationship may be changed;
the above description is only for the preferred embodiment of the present invention and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
