Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to an electric heating fuel preheating system for rail engineering vehicles. Background Art

[0002] The fuel system is located between the fuel tank and other oil-using components, such as the engine. It delivers fuel to the vehicle's engine and generator set, making it a crucial component. However, in cold winters, when ambient temperatures fall below the fuel's antifreeze requirements, waxing can occur, preventing the fuel system from properly delivering fuel. This can cause the engine and generator set to start improperly or even operate poorly. Therefore, improvements are needed to address this issue. Utility Model Content

[0003] The technical problem solved by the present invention is to provide an electric heating fuel preheating system for rail engineering vehicles. The purpose of the present invention is to avoid the problem of difficulty in starting the vehicle or stalling midway due to a sudden drop in temperature by improving the fuel delivery system.

[0004] In order to achieve the above purpose, the technical solution adopted by this utility model is:

[0005] An electric heating fuel preheating system for rail engineering vehicles, the electric heating fuel preheating system includes an air-heating oil suction pipe, an electric heating oil delivery pipe and a filter element heater. The air-heating oil suction pipe is installed on the fuel tank and can be used to draw oil from the fuel tank. One end of the electric heating oil delivery pipe is connected to the air-heating oil suction pipe, and the other end of the electric heating oil delivery pipe is connected to a fuel-using device on the rail vehicle through a filter element.

[0006] To further define the above solution, the gas-heated oil absorption pipe includes a gas-heated inner pipe and an oil absorption outer pipe sleeved outside the gas-heated inner pipe, and a heating wire is installed inside the gas-heated inner pipe.

[0007] As a further limitation of the above solution, the electric heating oil pipeline is an integrated structure consisting of an inner layer and an outer layer, and an electric heating wire is provided between the inner layer and the outer layer.

[0008] As a further limitation of the above solution, the filter element heater is wrapped around the outer surface of the filter element and clamped with a clamp.

[0009] As a further limitation of the above solution, a temperature sensor for detecting the temperature of the electric heating fuel preheating system is provided on the upper portion of the gas heating oil suction pipe.

[0010] To further limit the above solution, the electrically heated fuel preheating system also includes an intelligent controller, and the gas-heated oil suction pipe, electrically heated oil delivery pipe, filter element heater and temperature sensor are all electrically connected to the intelligent controller.

[0011] The advantages of this utility model compared with the prior art are:

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] It should be noted that, in this document, the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0019] See also Figure 1 , describe in detail the embodiments of the present utility model.

[0020] Example: See Figure 1 As shown, an electric heating fuel preheating system for rail engineering vehicles includes an air-heating oil suction pipe 1, an electric heating oil delivery pipe 2 and a filter element heater 5. The air-heating oil suction pipe 1 is installed on the fuel tank and can be used to take oil from the fuel tank. One end of the electric heating oil delivery pipe 2 is connected to the air-heating oil suction pipe 1, and the other end of the electric heating oil delivery pipe 2 is connected to the fuel-using equipment on the rail vehicle through a filter element 4. The filter element 4 is provided with a filter element heater 5.

[0021] The gas-heated oil suction pipe 1 is a device used to draw oil from the fuel tank and has filtering and heating functions. This heating function allows the fuel in the fuel tank to wax and, when powered, melt the fuel surrounding the suction pipe, ensuring a normal fuel supply. Specifically, the gas-heated oil suction pipe 1 comprises an inner gas-heated pipe and an outer oil-absorbing pipe that fits over the inner gas-heated pipe. The inner gas-heated pipe is internally installed with a heating wire. The gas-heated oil suction pipe 1 is secured to the fuel tank via a flange and, during installation, is submerged below the oil level in the tank.

[0022] The electrically heated oil pipeline is a dual-function oil pipeline that performs both electrical heating and oil transportation. While meeting normal oil transportation requirements, the heating circuit within the pipeline also heats the pipeline, preventing wax buildup in the fuel within the pipeline. Specifically, the electrically heated oil pipeline 2 is an integrated structure consisting of an inner layer and an outer layer, with an electric heating wire interposed between the inner and outer layers.

[0023] The filter element heater 5 is wrapped around the outer surface of the filter element 4 and clamped with a clamp. When powered on, the filter element can be heated to eliminate waxed fuel in the filter element.

[0024] There is no fixed way to connect the electric heating oil pipes and equipment in the electric heating fuel preheating system of this scheme. The installation method, pipe diameter and oil pipe length can be changed according to specific needs.

[0025] The control mode of this electric heating fuel preheating system can be operated by manual switch.

[0026] The control mode of this electric heating fuel preheating system can also adopt intelligent control operation. The specific settings are as follows:

[0027] A temperature sensor 3 for detecting the temperature of the electric fuel preheating system is provided on the upper portion of the gas-heated oil suction pipe 1. When the oil temperature changes, the temperature sensor 3 can automatically feed back to the intelligent thermostat, which can automatically heat or stop heating according to the temperature change.

[0028] The electrically heated fuel preheating system further comprises an intelligent controller 6 , and the gas heating oil suction pipe 1 , the electrically heated oil delivery pipe 2 , the filter element heater 5 and the temperature sensor 3 are all electrically connected to the intelligent controller 6 .

[0029] In this embodiment, the temperature feedback from the temperature sensor can be used to determine whether the heating elements such as the gas-heated oil suction pipe, the electric-heated oil pipeline, and the filter element heater are working or not. The intelligent controller controls whether each heating device needs to work through signals, and can also display the working status and heating faults.

[0030] This embodiment improves the intelligence of the fuel delivery system and controls the heating system to start or stop heating through a temperature sensor, thereby avoiding manual control and improving operation accuracy.
