Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a novel low-pressure oil pump with a high heat-resistant armature. Background Technology

[0002] In the automotive industry, the fuel pump, as a core component of the fuel supply system, directly impacts engine efficiency and fuel economy. Traditional fuel pump designs often suffer from performance degradation and insufficient fuel supply under high temperatures and harsh operating conditions, sometimes even leading to fuel system failure and disrupting vehicle operation. To address these issues, developing a new type of low-pressure fuel pump with a heat-resistant armature is crucial.

[0003] Traditional oil pumps typically feature thin impellers, resulting in a lower fuel delivery per revolution. This necessitates higher pump speeds, which in turn lead to higher temperatures. Under high temperature and pressure conditions, the impeller's heat resistance and stability are often insufficient, shortening the pump's lifespan and increasing maintenance costs. Furthermore, traditional oil pump designs have limitations in fuel delivery efficiency, failing to meet the high precision and stability requirements of modern engines.

[0004] Therefore, there is an urgent need for a new type of oil pump design that can maintain stable performance under high temperature and harsh operating conditions, improve fuel supply efficiency, reduce energy consumption, and extend the service life of the oil pump. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a novel low-pressure oil pump with a high-temperature-resistant armature. This solves the problem that traditional oil pumps typically have thin impellers, resulting in low oil supply per revolution. This necessitates increasing the pump's speed, which in turn leads to high temperatures. Under high temperature and high pressure conditions, the impeller's heat resistance and stability are often insufficient, leading to a shortened pump lifespan and increased maintenance costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel low-pressure oil pump for a heat-resistant armature, comprising:

[0007] The oil pump body includes:

[0008] case;

[0009] The lower end cover is fixedly installed at the bottom of the housing. The bottom of the lower end cover has an oil inlet, and the interior of the lower end cover has a widened receiving groove.

[0010] The upper end cap is fixedly installed on the top of the housing;

[0011] Armature unit, comprising:

[0012] The armature body is installed inside the housing;

[0013] A drive shaft, one end of which is connected to the armature body, and the other end of which extends into the widened receiving groove;

[0014] The thickened impeller is rotatably mounted at the end of the drive shaft and rotatably mounted in the widened receiving groove;

[0015] The pump utilizes the suction generated by the rotation of the thickened impeller in the widened receiving groove to draw fuel from the fuel tank connected to the fuel inlet into the pump, and the thickened impeller also increases the fuel supply per revolution.

[0016] Preferably, an oil injection pipe is installed on the top of the upper end cover, and the oil injection pipe is connected to the engine's fuel injection system.

[0017] Preferably, a one-way oil outlet valve is installed in the oil injection pipe.

[0018] Preferably, a plug is fixedly connected to the top of the upper cover.

[0019] Preferably, a magnet is fixedly connected inside the housing, and the magnet is located outside the armature body.

[0020] Preferably, the oil inlet is connected to the oil tank via an oil pipeline.

[0021] Preferably, the top of the upper cover is provided with a safety valve for releasing pressure outward.

[0022] Preferably, the thickened impeller is made of a high-temperature resistant alloy material.

[0023] Preferably, the thickness of the thickened impeller is set to 4.5 mm.

[0024] Preferably, the plug provides electrical power to the armature body via internal wires.

[0025] This utility model discloses a novel low-pressure oil pump with a high heat-resistant armature, which has the following beneficial effects:

[0026] 1. This novel low-pressure oil pump with a high-temperature resistant armature utilizes a thickened impeller and a widened receiving groove. As the impeller thickness increases, its blades can more effectively capture and propel the fluid. The thicker blades provide a larger surface area and greater structural strength, thus better resisting the resistance and pressure of fluid flow. This effect allows the impeller to deliver more fuel per revolution. The increased impeller thickness also means a larger swept volume, i.e., the space occupied by the blades per revolution. At the same rotational speed, the thickened impeller can extract and deliver more fuel per revolution, thereby improving the pump's volumetric efficiency and increasing the fuel supply per revolution. This allows the required fuel supply pressure to be achieved at a lower rotational speed, reducing ambient temperature and further stabilizing the thickened impeller structure.

[0027] 2. This new type of low-pressure oil pump with a high-temperature resistant armature features a thickened impeller that not only increases the oil supply per revolution but also enhances the overall structural strength and durability of the pump. This helps reduce wear and failures that may occur during long-term operation and under harsh conditions, thereby further improving the reliability and service life of the oil pump.

[0028] 3. This new type of high-heat-resistant armature low-pressure oil pump first supplies electrical energy to the armature body via a plug during operation. After being energized, the armature body generates an alternating magnetic field, which interacts with a magnet fixedly connected inside the housing, generating electromagnetic force that drives the armature body to rotate. The rotation of the armature body drives the drive shaft to rotate synchronously, which in turn drives the thickened impeller to rotate within the widened receiving groove. During rotation, the thickened impeller, through its special blade design, generates a strong suction force, drawing fuel from the fuel tank into the pump through the inlet. After being pressurized within the pump, the fuel is delivered to the engine's fuel injection system through the injection pipe. A one-way outlet valve is installed in the injection pipe to prevent fuel backflow and ensure a stable fuel supply. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This application provides a novel low-pressure oil pump with a heat-resistant armature, which solves the problem that traditional oil pumps typically have thin impellers, resulting in low oil supply per revolution. This necessitates increasing the pump's speed, which in turn leads to high temperatures. Under high temperature and high pressure conditions, the impeller's heat resistance and stability are often insufficient, resulting in a shortened pump life and increased maintenance costs.

[0035] By utilizing the thickened impeller 23 and widened receiving groove 122, the blades can more effectively capture and propel the fluid as the impeller thickness increases. The thicker blades provide a larger surface area and stronger structural strength, thus better resisting the resistance and pressure during fluid flow. This effect allows the impeller to deliver more fuel per revolution. At the same rotational speed, the thickened impeller can extract and deliver more fuel per revolution, thereby improving the volumetric efficiency of the oil pump and increasing the fuel supply per revolution. This allows the required fuel supply pressure to be achieved at a lower rotational speed, which in turn reduces the ambient temperature, making the structure of the thickened impeller 23 more stable.

[0036] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0037] This utility model discloses a novel low-pressure oil pump for a heat-resistant armature.

[0042] The upper end cover 13 is fixedly installed on the top of the housing 11;

[0043] Armature unit 2, which includes:

[0044] Armature body 21, which is installed inside housing 11;

[0045] The drive shaft 22 has one end connected to the armature body 21, and the other end of the drive shaft 22 extends into the widened receiving groove 122.

[0046] The thickened impeller 23 is rotatably mounted at the end of the drive shaft 22 and rotatably mounted in the widened receiving groove 122;

[0047] The thickened impeller 23 generates suction by rotating in the widened receiving groove 122, drawing fuel from the fuel tank connected to the fuel inlet 121 into the pump, and the thickened impeller 23 increases the fuel supply per revolution.

[0048] By utilizing the thickened impeller 23 and widened receiving groove 122, the blades can more effectively capture and propel fluid as the impeller thickness increases. The thicker blades provide a larger surface area and greater structural strength, thus better resisting fluid flow resistance and pressure. This effect allows the impeller to deliver more fuel per revolution. The increased impeller thickness also means a larger swept volume, i.e., the space occupied by the blades per revolution. At the same rotational speed, the thickened impeller can extract and deliver more fuel per revolution, thereby improving the volumetric efficiency of the oil pump and increasing the fuel supply per revolution. This allows the required fuel supply pressure to be achieved at a lower rotational speed, reducing ambient temperature and further stabilizing the structure of the thickened impeller 23.

[0049] The thickened impeller not only increases the oil supply per revolution but also enhances the overall structural strength and durability of the oil pump. This helps reduce wear and failures that may occur during long-term operation and under harsh conditions, thereby further improving the reliability and service life of the oil pump.

[0050] Furthermore, an oil injection pipe 131 is installed on the top of the upper cover 13, and the oil injection pipe 131 is connected to the engine's fuel injection system.

[0056] Furthermore, the thickened impeller 23 is made of high-temperature resistant alloy material, and the thickness of the thickened impeller 23 is set to 4.5mm.

[0057] Furthermore, the plug 14 provides electrical power to the armature body 21 through internal wires.

[0058] During operation, electrical energy is first supplied to the armature body 21 through the plug 14. After being energized, the armature body 21 generates an alternating magnetic field, which interacts with the magnet 24 fixedly connected inside the housing 11 to generate an electromagnetic force, driving the armature body 21 to rotate.

[0059] The rotation of the armature body 21 drives the drive shaft 22 to rotate synchronously, which in turn drives the thickened impeller 23 to rotate in the widened receiving groove 122. During the rotation, the thickened impeller 23 generates a strong suction force through its special blade design, drawing fuel from the fuel tank into the pump through the fuel inlet 121.

[0060] After being pressurized in the pump, the fuel is delivered to the engine's fuel injection system through the fuel injection pipe 131. A one-way fuel outlet valve 132 is installed in the fuel injection pipe 131 to prevent fuel backflow and ensure a stable fuel supply.

[0061] By utilizing the thickened impeller 23 and widened receiving groove 122, the blades can more effectively capture and propel fluid as the impeller thickness increases. The thicker blades provide a larger surface area and greater structural strength, thus better resisting fluid flow resistance and pressure. This effect allows the impeller to deliver more fuel per revolution. The increased impeller thickness also means a larger swept volume, i.e., the space occupied by the blades per revolution. At the same rotational speed, the thickened impeller can extract and deliver more fuel per revolution, thereby improving the volumetric efficiency of the oil pump and increasing the fuel supply per revolution. This allows the required fuel supply pressure to be achieved at a lower rotational speed, reducing ambient temperature and further stabilizing the structure of the thickened impeller 23.
