Technical Field

[0001] This utility model relates to a diesel pump with built-in rollers. Background Technology

[0002] The current domestic market uses this type of oil pump for diesel vehicles, but the existing oil pumps use an impeller structure, which has low performance.

[0003] Diesel fuel viscosity increases at low temperatures (below -20°C), under which impeller-type oil pumps cannot deliver the rated fuel properly. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a diesel pump with built-in rollers. By replacing the impeller with a roller pump body, the performance of the oil pump is improved, and the difficulty of pumping oil under low-temperature conditions is solved.

[0005] The objective of this utility model can be achieved through the following technical solution: a diesel pump with built-in rollers, comprising an armature assembly, a brush holder assembly installed at one end of the armature assembly, a magnetic tile assembly installed on the outer surface of the armature assembly, a housing, an end cover, and a rear cover, wherein the housing is fitted onto the armature assembly, and the end cover and the rear cover are installed at both ends of the housing and the end cover is also connected to the brush holder, characterized in that a roller pump body is connected to the lower end of the armature assembly.

[0006] Furthermore, the roller pump body is a roller mechanical pump.

[0007] Furthermore, the magnetic tile assembly includes two semi-circular magnetic tiles symmetrically arranged on the surface of the armature assembly.

[0008] Furthermore, a retaining ring is provided between the two magnetic tiles.

[0009] Furthermore, the armature assembly has a diameter of 26 mm and a length of 26 mm.

[0010] Furthermore, the top of the brush holder assembly is a tab that is inserted into the end cap.

[0011] Furthermore, the connections between the end cap, housing, and rear cover are all sealed.

[0012] Compared with the prior art, the advantages of this application are: by replacing the impeller with a roller pump body, the performance of the oil pump is improved and the difficulty of pumping oil under low temperature conditions is solved. Attached Figure Description

[0020] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0021] like Figure 1-6 As shown, a diesel pump with built-in rollers includes an armature assembly 6, a brush holder assembly 11 installed at one end of the armature assembly 6, a magnetic tile assembly installed on the outer surface of the armature assembly 6, a housing 2, an end cover 1, and a rear cover 3. The housing 2 is fitted onto the armature assembly 6, and the end cover 1 and the rear cover 3 are installed at both ends of the housing 2, with the end cover 1 also connected to the brush holder. The characteristic feature is that a roller pump body 5 is connected to the lower end of the armature assembly 6.

[0022] Furthermore, the roller pump body 5 is a roller mechanical pump.

[0023] Furthermore, the magnetic tile assembly includes two semi-circular magnetic tiles 4 symmetrically arranged on the surface of the armature assembly 6.

[0024] Furthermore, a retaining ring 41 is provided between the two magnetic tiles 4, allowing the magnetic tiles 4 to abut against armature assemblies 6 of different sizes.

[0025] Furthermore, the armature assembly 6 has a diameter of 26mm and a length of 26mm. The existing motor diameter is relatively small at 23.5mm, which cannot meet the requirements for high-performance speed output. The improved version increases the motor diameter to 26mm, thereby increasing the motor's output power.

[0026] Furthermore, the top of the brush holder assembly 11 is a tab 111 that is inserted into the end cap 1.

[0027] Furthermore, the connections between the end cap 1, the housing 2, and the rear cover 3 are all sealed.

[0028] This application uses a roller pump body 5 (mechanical pump) with increased volume to replace the existing impeller assembly, thereby improving the performance of the oil pump and solving the problem of difficulty in pumping oil at low temperatures.

[0029] Oil pump section: The impeller assembly is replaced by a roller pump body 5, and the volume of the roller pump body 5 assembly is increased to increase the oil flow rate and improve the performance of the oil pump.

[0030] Motor section (armature assembly 6): While increasing the volume of the roller pump body 5, it is also necessary to ensure sufficient motor power output to reach a certain speed to meet the flow output requirements. Therefore, the overall power of the motor is increased.

[0031] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0032] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
