[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] In the present invention, the lubricating oil pump with four-way oil supply has a compact structure and improves space utilization. Through precise structural design, the electromagnetic relay, plunger pump body and shell are tightly combined to achieve the compactness of the overall structure. This design not only reduces the volume and weight of the oil pump, but also greatly improves the utilization rate of the internal space of the engine. Within the limited installation space, the oil pump can efficiently complete the oil supply task of multiple lubrication points, providing a strong guarantee for the stable operation of the engine. At the same time, the compact structure also helps to reduce the vibration and noise of the oil pump and improve the operation quality of the whole machine.
[0013] In the present invention, the lubricating oil pump with four-way oil supply distributes the flow evenly to ensure the lubrication effect. The precise flow distribution mechanism designed inside the oil pump ensures that each lubrication point can obtain a uniform and sufficient amount of lubricating oil. By adjusting the stroke and frequency of the plunger and optimizing the layout and size of the oil cavity in the shell, the oil pump can accurately control the amount of lubricating oil in each oil circuit, avoiding component wear and failure caused by uneven lubrication. This uniform lubrication effect not only extends the service life of the engine, but also improves the operating efficiency and reliability of the entire machine.
[0014] In the present invention, the four-way oil supply lubricating oil pump has excellent low-temperature resistance and can adapt to extreme environments. In view of the special needs of unmanned engines working in low-temperature environments, this lubricating oil pump adopts low-temperature resistant materials and optimized design to ensure that the oil pump can still maintain good working performance under extremely cold conditions. The application of low-temperature resistant alloy materials improves the mechanical properties and sealing of the oil pump components, while the optimized filter design and heating device further improve the oil suction efficiency and reliability of the oil pump in low-temperature environments. This excellent low-temperature resistance enables the oil pump to adapt to various extreme environments and provides strong support for the continuous operation of the engine.
[0015] In the present invention, the electronic control system of the lubricating oil pump with four-way oil supply is integrated to realize automatic control. The close integration of the lubricating oil pump and the electronic control system realizes the automatic control of the oil pump. By receiving the pulse control signal from the ECU, the oil pump can accurately adjust the working state and the amount of lubricating oil to meet the lubrication needs of the engine under different working conditions. This integrated and automated control method not only improves the working efficiency and reliability of the oil pump, but also simplifies the design and maintenance process of the lubrication system. At the same time, it also helps to realize the intelligent management of the engine and improve the intelligence level of the whole machine.
[0016] In the present invention, the lubricating oil pump with four-way oil supply reduces maintenance costs and improves economic benefits. The lubricating oil pump adopts a simple structure and high reliability design, and has excellent properties such as automatic control and low temperature resistance.

[0020] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.
[0021] See also Figure 1 and Figure 2The present invention provides a lubricating oil pump with four-way oil supply, including a lubricating oil pump body 1, the lubricating oil pump body 1 includes an electromagnetic relay component, a plunger pump component and a shell assembly, a lubricating oil tank 11 is arranged on the lubricating oil pump body 1, a lubricating oil filter 12 is arranged between the lubricating oil pump body 1 and the lubricating oil tank 11, a crankcase 13 is arranged below the lubricating oil pump body 1, an air pump 14 is arranged on one side of the lubricating oil pump body 1, and an electronic control unit (ECU) is connected to the electromagnetic relay component, wherein the electromagnetic relay component of the lubricating oil pump body 1 is installed on one side or the top of the shell assembly, a top opening is opened on the shell assembly of the lubricating oil pump body 1, and the top opening is fixedly connected to the oil delivery end of the lubricating oil tank 11, the shell assembly of the lubricating oil pump body 1 has four independent oil chambers built in, and the plunger pump component of the lubricating oil pump body 1 is located in the shell. Inside the component, the plunger pump assembly of the lubricating oil pump body 1 is connected to the electromagnetic relay assembly, and each independent oil chamber is provided with an oil outlet channel. The plunger pump assembly of the lubricating oil pump body 1 includes four plungers, and the four plungers are arranged corresponding to the four oil chambers. When the engine is started, the ECU sends a pulse control signal to the electromagnetic relay according to the preset program. After the relay receives the signal, its internal armature moves under the action of the electromagnetic force, and drives the plunger to reciprocate in the shell through the mechanical structure connection. As the plunger moves up and down, the volume of the oil chamber in the shell changes periodically, forming a cycle of oil suction and discharge. The lubricating oil first enters the shell through the filter, and is then evenly distributed to the four oil chambers. Driven by the plunger, the lubricating oil in each oil chamber is pressed into the corresponding oil circuit one by one, and finally delivered to the crankcase, air pump and other lubrication points.
[0022] The electromagnetic relay component of the lubricating oil pump body 1 is a high-sensitivity, low-power and low-temperature resistant model to ensure stable operation in extreme environments. The filter screen of the lubricating oil filter 12 is made of low-temperature resistant and corrosion-resistant materials. The filter screen is used to filter the lubricating oil entering the oil pump to prevent impurities from entering the lubrication system.
[0023] The electromagnetic relay assembly includes a coil, an armature and a reset spring. After receiving the pulse signal from the ECU, the coil generates a magnetic field, attracts the armature to drive the plunger to move, and realizes the pumping of the lubricating oil. The reset spring resets the armature and the plunger after the pulse signal ends. The electromagnetic relay assembly of the lubricating oil pump body 1 includes a circuit plug, which is arranged at the coil.
[0024] A flow regulating mechanism is designed inside the lubricating oil pump body 1 for accurately controlling the lubricating oil flow in each oil channel to meet the specific needs of different lubrication points. A heat dissipation structure is arranged outside the shell assembly of the lubricating oil pump body 1.
[0025] Working principle:
[0026] 1. The four-channel oil supply lubrication oil pump is specially designed to meet the multi-point lubrication needs of medium-sized heavy-oil unmanned engines. It has a compact and efficient structure. The oil pump is mainly composed of an electromagnetic relay part, a plunger pump body and a shell. There are oil holes, oil channels and filters on the top of the shell to receive the lubricating oil flowing in from the oil tank by gravity. The inside of the shell is finely divided into four independent oil chambers, each of which corresponds to an independent lubrication point to ensure that the lubricating oil can be evenly distributed. The electromagnetic relay part is located in front of the oil pump and is connected to the electronic control system through a unified plug to receive pulse control signals from the ECU, thereby driving the plunger pump body to work.
[0027] Second, when the engine starts, the ECU sends a pulse control signal to the electromagnetic relay according to the preset program. After the relay receives the signal, its internal armature moves under the action of electromagnetic force, and drives the plunger to reciprocate in the shell through the mechanical structure connection. As the plunger moves up and down, the volume of the oil chamber in the shell changes periodically, forming a cycle of oil suction and discharge. The lubricating oil first enters the shell through the filter, and is then evenly distributed to the four oil chambers. Pushed by the plunger, the lubricating oil in each oil chamber is pressed into the corresponding oil circuit one by one, and finally delivered to the crankcase, air pump and other lubrication points.
[0028] Third, in order to achieve uniform lubrication of multiple lubrication points, the lubricating oil pump is designed with a precise flow distribution mechanism inside. By adjusting the stroke and frequency of the plunger, the amount of lubricating oil in each oil circuit can be accurately controlled. At the same time, the design of the oil chamber in the shell also fully considers the uniformity of oil flow, ensuring that the lubricating oil in each oil chamber can be pressed out simultaneously and in equal amounts during each oil pressure of the plunger. In addition, the oil pump also has an automatic adjustment function, which can adjust the amount of lubricating oil in real time according to the working status and lubrication requirements of the engine, ensuring that all engine components are always in a good lubrication state.
[0029] Fourth, in response to the special needs of unmanned engines working in low-temperature environments, this lubricating oil pump adopts low-temperature resistant materials and optimized design. First, key components such as the shell and plunger are made of alloy materials with excellent low-temperature performance to ensure that they can still maintain good mechanical properties and sealing under extremely cold conditions. Secondly, the filter design of the oil pump also fully considers the fluidity of the oil at low temperatures. By optimizing the filter aperture and arrangement, the resistance of the oil passing through the filter is effectively reduced, and the oil suction efficiency of the oil pump in low-temperature environments is improved. In addition, the oil pump is also equipped with a heating device, which can automatically start the heating function when necessary to increase the oil temperature and ensure the normal operation of the oil pump in low-temperature environments.
[0030] 5. Another highlight of the four-channel oil supply lubrication oil pump is its close integration with the electronic control system. After the circuit is connected to the electronic control system through a unified plug, the oil pump can receive the pulse control signal from the ECU to realize automatic control. The ECU adjusts the frequency and duty cycle of the pulse signal in real time according to the working status and lubrication requirements of the engine, thereby accurately controlling the working status and amount of lubricating oil of the oil pump. This integrated and automated control method not only improves the working efficiency and reliability of the oil pump, but also greatly simplifies the design and maintenance process of the lubrication system. At the same time, since the electromagnetic relay is used as the power source inside the oil pump, self-driving operation can be achieved without an additional power device, further reducing the complexity and cost of the system.
