Description

Technical Field

[0001] The invention belongs to the technical field of diesel engine lubrication systems, and in particular relates to an oiler for lubricating a starting air distributor of a diesel engine. Background Art

[0002] High-power diesel engines have heavy moving parts, resulting in significant hysteresis torque during startup. Therefore, compressed air starting systems are typically used for starting. Currently, most high-power diesel engines still use a mechanical air distributor for starting. This distributor, driven by the engine's camshaft, controls the sequence, timing, and duration of compressed air flow to the starting control valve on the cylinder head. This controls the sequence, timing, and duration of the opening of the starting control valve, ensuring that starting air enters the cylinders at the desired moment and for a specified duration, pushing the pistons and rotating the crankshaft. Once the engine reaches ignition speed, ignition is successfully achieved. After a successful start, the compressed air is disconnected, and the distributor plate separates from the engine body, eliminating contact. During engine startup, the two ends of the distributor plate are unequal. The compressed air entering the plate generates a rightward thrust, forcing the plate to fit tightly against the housing and preventing compressed air from escaping between them. Since both the distributor plate and the housing are made of metal, dry friction between the metals, if not lubricated, can cause wear and tear, potentially preventing continued operation. For this purpose, an oiler is installed on the front system of the air distributor. The function of the oiler is: when the diesel engine is started, an appropriate amount of lubricating oil is injected into the control air pipeline from the oiler. After the lubricating oil is mixed with the compressed air, it flows through the mechanical air distributor to lubricate the distribution plate and the distributor body, avoiding dry friction between the distribution plate and the distributor body bracket, causing wear and damage to parts.

[0003] Currently used Figure 7-8 The working principle of the lubricator shown is: at startup, after the compressed air is connected, the compressed air opens the one-way valve A2 through hole A1, and then passes through holes A3 and A4 to the oil tank A5. Since the oil pressure generated by the pressure in the oil tank A5 is greater than the oil pressure on the A6 side, the lubricating oil is injected into the pipeline from A7 through the one-way valve A8 and mixed with the compressed air to lubricate the distribution plate and the distributor body. However, there are the following defects during use: ① The amount of oil injected into the lubricator depends on the aperture size of the hole A7 connected to the oil tank A8. The aperture determines the amount of oil injected. If adjustment is required, the hole A7 needs to be reprocessed; ② At startup, compressed air enters the lubricator and comes into contact with the lubricating oil. Some tiny dust in the air will gradually contaminate the lubricating oil and produce scaling. The dirt will clog the oil pipe, making the lubricator unable to inject oil or reducing the amount of oil injected, resulting in abnormal wear of the mechanical distributor. Therefore, it is necessary to make improvements to the above problems. Summary of the Invention

[0016] The advantages of the present invention compared with the prior art are:

[0017] 1. This technical solution utilizes the pressure of compressed air itself to allow a small portion of compressed air in the oil-gas passage to enter the housing through the compressed air hole. After applying pressure to the left end of the plunger, the lubricating oil in the oil chamber enters the oil-gas passage through the one-way valve assembly and the lubricating oil hole, where it is mixed with the compressed air and sent to the diesel engine distributor. To achieve the mixing condition of the lubricating oil and the compressed air in the oil-gas passage, under the action of the compressed air in the oil-gas passage, only a small portion of the compressed air in the oil-gas passage needs to be filled into the gap in the housing located at the connection between the left end of the plunger and the compressed air hole. No other power structure is required.

By fixing a T-shaped column in the tailstock and positioning a return spring connected to the T-shaped column against the central guide groove on the right end face of the plunger, when there is no compressed air in the oil and gas passage, the return spring pushes the plunger back to its original position. At this time, a negative pressure state is created in the oil chamber, thereby opening the one-way valve assembly and allowing the lubricating oil in the oil tank to flow into the oil chamber. The oil chamber can be automatically filled with oil without the need for any other oil filling structure.

[0019] 3. This technical solution provides conditions for automatic on-off between the oil tank and the oil chamber, and between the oil chamber and the oil hole, by installing a one-way valve assembly on the oil tank and the base flange, and a one-way valve group device on the base. This eliminates the need for manual control and achieves automatic on-off control based on changes in internal pressure.

[0020] 4. This technical solution has a simple structure, novel design, mechanical automatic on-off control, and adopts an oil tank with filtering and dustproof function, which effectively solves the problems of traditional lubricators that the oil filling amount cannot be adjusted and the oil injector is blocked. It eliminates the contamination, blockage, and gradual reduction of oil filling amount or inability to inject oil in the lubricator, avoids abnormal wear between the distribution plate and the housing of the mechanical air distributor, and protects the reliability of diesel engine starting.

[0033] Among them, a plurality of distance sleeves are evenly distributed between the upper end surface of the base 1 and the base flange 2, and the base 1 and the base flange 2 are fixedly connected to the distance sleeves by bolts, thereby realizing a detachable fixed connection between the base 1 and the base flange 2. This structure provides conditions for reliable support of the oil tank 6 while realizing reliable fixation of the flow-adjustable oil injection device;

[0034] like Figure 2-5As shown, the specific structure of the flow-adjustable oil injection device is as follows: the flow-adjustable oil injection device includes a plunger 11, a housing 8 with openings at both ends, an adjustment seat 9 and a tail sleeve 10 respectively sealed and fixed to the two ends of the housing 8, the plunger 11 is slidably sealed inside the housing 8, and the right end of the plunger 11 extends into the tail sleeve 10 and is adapted to be connected to the elastic reset device provided inside the tail sleeve 10, an oil chamber 7 is formed between the right end surface of the convex ring on the outer circumferential wall of the left end of the plunger 11 and the step surface on the left end of the stepped inner hole of the housing 8, and the oil chamber 7 is communicated with the one-way valve assembly through the oil inlet on the plunger 11, and a valve is provided in the housing 8 at the outside of the left end of the plunger 11 and in contact with the adjustment seat 9. The oil control plate 13 connected to the positioning is axially positioned and sealed in the through hole in the middle of the adjustment seat 9, and the right end of the adjusting bolt 12 is threadedly connected to the middle of the oil control plate 13. The right end of the adjusting bolt 12 passes through the oil control plate 13 and extends into the central hole on the left end face of the plunger 11. With the cooperation of the elastic reset device, the oil control plate 13 controls the plunger 11 to move left or right by rotating the adjusting bolt 12, thereby adjusting the size of the oil chamber 7 and completing the regulation of the oil filling amount. In the above structure, when the size of the oil chamber 7 needs to be adjusted, the adjusting bolt 12 is rotated to make the oil control plate 13 push the plunger 11 to the right. At this time, the volume of the oil chamber 7 becomes smaller and the amount of oil stored inside is reduced. Figure 5 On the contrary, reverse rotation of the adjusting bolt 12, the oil control plate 13 moves to the left, at this time, under the action of the elastic reset device pushes the plunger 11 to the left to the limit position, such as Figure 4 As shown, at this time, the volume of the oil chamber 7 is the largest, the oil injection amount is at the maximum position, and the oil injection amount of the oil injector is easy and quick to adjust;

[0035] Among them, an L-shaped compressed air inlet corresponding to the upper end position of the compressed air hole 4 is made at the lower end surface of the adjustment seat 9. The compressed air inlet is connected to the interior of the shell 8. A plunger with a central air hole is sealed at the compressed air inlet position, and the other end hole of the compressed air hole 4 is connected to the central air hole of the plunger.

[0036] In the above structure, in order to quickly and easily grasp the size of the oil injection amount in the oil chamber 7, an observation groove is specially processed on the tail sleeve 10, and a scale is provided on the outer wall of the tailstock 10 at the position of the observation groove. In this way, the scale corresponding to the right end of the plunger 11 can be clearly viewed through the observation groove, and the oil injection amount can be directly read. The size of the oil chamber 7 can be clearly seen, and adjustment and operation are convenient.

[0037] like Figure 2-5As shown, the specific structure of the elastic reset device is as follows: the elastic reset device includes a reset spring 14 and a T-shaped column 15. The T-shaped column 15 is coaxially arranged in the tail sleeve 10, and the large end of the T-shaped column 15 is fixed to the inner end surface of the right end of the tail sleeve 10. One end of the reset spring 14 is sleeved on the small diameter section of the T-shaped column 15 and abuts against the step surface formed by the small diameter section and the large diameter section. The other end of the reset spring 14 extends into the central guide groove of the right end surface of the plunger 11 and abuts against the bottom surface of the central guide groove. In the above structure, the reset spring 14 is used to provide a reset thrust to the plunger 11, so that the interior of the oil chamber 7 is in a negative pressure state, thereby providing the required negative pressure for connecting the one-way valve assembly.

[0038] like Figure 2-5 As shown, the radial positioning connection between the oil control plate 13 and the adjustment seat 9 is specifically as follows: at least two guide rods 16 are evenly distributed on the left end surface of the oil control plate 13, and the guide rods 16 are adapted to the guide holes at the corresponding positions on the right end surface of the adjustment seat 9, and the radial positioning connection between the oil control plate 13 and the adjustment seat 9 is realized with the cooperation of the guide rods 16 and the guide holes. The above structure provides guide adjustment for the horizontal movement of the oil control plate 13, while preventing the oil control plate 13 from rotating, thereby ensuring stable and reliable horizontal movement of the oil control plate 13.

[0039] Among them, in order to ensure the sealing performance of the oil chamber 7, the following sealing structure is specially adopted: a sealing groove is formed on the outer wall of the convex ring of the plunger 11, and an O-ring 17 is provided in the sealing groove to seal with the inner wall of the housing 8; an O-ring 17 is provided in the stepped hole of the housing 8, which is located between the right step surface of the stepped hole and the tail sleeve 10 and is used to seal the plunger 11, the housing 8 and the tail stock 10; a Y-ring 18 is fixed to the left end of the plunger 11 and is in contact with the hole wall of the housing 8; specifically, a sealing ring is provided at the step position between the adjusting bolt 12 and the middle through hole of the adjusting seat 9, and a sealing ring is provided on the outer wall of the step position of the small diameter section at the right end of the adjusting seat 9 to contact the inner hole wall of the right end of the housing 8.

[0040] like Figure 2-5As shown, the specific structure of the one-way valve assembly is as follows: the one-way valve assembly includes an oil suction stud 19 with a large head end located in the oil tank 6 and a steel ball 20 provided at the lower end of the oil suction stud 19, the lower end of the oil suction stud 19 passes through the oil outlet hole on the bottom surface of the oil tank 6 and is threadedly fixed to the mounting hole position on the base flange 2, and the steel ball 20 is located in the mounting hole, and the lower hole of the mounting hole corresponds to and is connected to the T-hole position provided on the outer wall of the shell 8 in the flow-adjustable oil injection device and connected to the oil chamber 7, and a sealing ring is provided on the inner hole wall of the T-hole, the oil suction stud 19 is provided with two upper ports located on its two side walls and connected to the inside of the oil tank 6, and the lower port is located at the T-shaped oil hole 21 on the lower end surface of the oil suction stud 19, the lower end of the oil suction stud 19 The surface is an arc surface adapted to the steel ball 20, and the steel ball 20 moves downward when there is no compressed air in the oil and gas channel 3 to connect the oil chamber 7 with the oil tank 6 through the T-shaped oil hole 21, and when there is compressed air in the oil and gas channel 3, the steel ball 20 moves upward to contact the arc surface of the lower end of the oil suction stud 19 to isolate the oil chamber 7 from the oil tank 6; in the above structure, conditions are provided for the connection and disconnection of the oil tank 6 and the oil chamber 7, so that when there is compressed air in the oil and gas channel 3, the steel ball 20 moves upward to contact and seal the lower end surface of the oil suction stud 19 to isolate the oil chamber 7 from the oil tank 6, and after the compressed air in the oil and gas channel 3 is withdrawn, the plunger 11 is pushed back under the action of the reset spring 14, so that the oil chamber 7 with a certain negative pressure is connected to the oil tank 6 after the steel ball 20 moves downward, and oil is filled into the oil chamber 7.

[0041] like Figure 2-6 As shown, the specific structure of the one-way valve group device is as follows: the one-way valve group device includes a horizontal elastic one-way valve group and a vertical elastic one-way valve group, wherein the vertical elastic one-way valve group is vertically installed on the upper end surface of the base 1, and the upper end of the vertical elastic one-way valve group is sealed with the lubricating oil outlet on the shell 8 in the flow-adjustable oil injection device, the horizontal elastic one-way valve group is horizontally installed on the side wall of the base 1, the left end of the horizontal elastic one-way valve group is connected to the lubricating oil hole 5, and the right end of the horizontal elastic one-way valve group is connected to the lower end of the vertical elastic one-way valve group through the oil channel 22.

[0042] like Figure 6As shown, the horizontal elastic one-way valve group includes a spring 23, an oil-passing plunger 24 and a connecting plug 25. The connecting plug 25 is a T-shaped columnar structure. The small diameter section of the connecting plug 25 is threadedly connected to the threaded hole on the side wall of the base 1 that is connected to the lubricating hole 5, and the step surface formed by the large diameter section and the small diameter section of the connecting stud 25 is against the side wall of the base 1. The outer wall of the left end of the connecting plug 25 is in contact with the sealing ring in the sealing groove on the wall of the smooth wall section of the threaded hole. The oil-passing plunger 24 is adapted to be installed in the inner hole of the small diameter section of the connecting plug 25, and one end of the spring 23 sleeved on the small diameter section of the oil-passing plunger 24 is against the step surface of the oil-passing plunger 24. The oil passage 22 is connected to the inner hole of the small diameter section of the connecting plug 25 through the oil passage 22. When compressed air is present in the oil-gas passage 3, the lubricating oil in the oil passage 22 causes the oil passage 24 to move leftward and flows into the oil-gas passage 3 through the Y-shaped oil hole 26, the inner hole of the small diameter section of the connecting plug 25 and the lubricating oil hole 5.

[0043] The vertical elastic one-way valve group includes a spring 23, an oil-through plunger 24 and an oil-through plunger 27. The small diameter section of the upper end of the oil-through plunger 27 is adapted to the lubricating oil outlet on the housing 8, and the large diameter section of the lower end of the oil-through plunger 27 is threadedly connected to the mounting hole on the upper end face of the base 1 and is sealed by a sealing ring provided on the large diameter section of the oil-through plunger 27 and in contact with the wall of the mounting hole and the housing 8. The oil-through plunger 24 and the spring 23 sleeved on the small diameter section of the lower end of the oil-through plunger 24 are both provided on the base 1. The oil passage 22 is connected with the mounting hole on the upper end face of the base 1, and the lubricating oil in the oil chamber 7 causes the oil passage 24 to move downward and pass through the central oil hole of the oil plug column 27 and the Y-shaped oil hole 26.

[0044] When compressed air is present in the oil-gas passage 3, the compressed air applies rightward pressure to the plunger 11, causing the oil-passing plunger 24 in the horizontal elastic one-way valve assembly to move downward and the oil-passing plunger 24 in the vertical elastic one-way valve assembly to move leftward, thereby achieving oil discharge after the oil hole 5 is connected to the oil chamber 7;

[0045] like Figure 2As shown, the specific structure of the oil tank 6 is as follows: the oil tank 6 includes a box body 6-1 with an open upper end, an upper cover 6-2 sealed and fixed to the upper port of the box body 6-1, a top cover 6-3 threadedly connected to the upper end of the upper cover 6-2, and a filter cartridge 6-4 arranged in the box body 6-1, the upper cover 6-2 is an annular structure with open ends and an upper end size smaller than the lower end size, the T-ring at the upper end of the filter cartridge 6-4 is overlapped at the upper port position of the upper cover 6-2, and the inverted cone filter cartridge fixed on the T-ring is located in the box body 6-1.

[0046] In this solution, the pressure difference generated by the compressed fluid on the pressure-bearing areas of different sizes when the pressure is the same is utilized. There is no external drive, the cost is low, and the lubricating oil in the oil tank 6 is not in direct contact with the compressed air. Therefore, the lubricating oil in the oil tank 6 will not be contaminated by dust in the air.
