Description

Technical Field

[0001] The utility model relates to a device for heating the internal oil of a combined speed governor of an internal combustion locomotive, belonging to the technical field of maintenance equipment for internal combustion locomotives. Background Art

[0002] The combined speed governor of a diesel locomotive needs to be tested when a problem occurs or after maintenance. During normal operation, the temperature of the oil inside the combined speed governor is approximately 70 degrees Celsius. Therefore, when testing the combined speed governor, the oil temperature must also reach 70 degrees Celsius, otherwise the test results will be significantly inaccurate. However, since it is impossible to heat the oil inside the combined speed governor in the laboratory, it is difficult to reach the oil temperature of 70 degrees Celsius by relying on the heat generated by the laboratory drive device to drive the combined speed governor. Therefore, laboratory staff can only test the combined speed governor at room temperature. Although some laboratories can use air conditioning systems to increase the room temperature, they still cannot achieve an oil temperature of 70 degrees Celsius, which seriously affects the accuracy of the test results. Therefore, it is very necessary to design a combined speed governor oil heating device for use in the laboratory. Utility Model Content

[0014] In response to the shortcomings of the prior art, the utility model provides a combined speed regulator oil heating device. The device utilizes the internal oil pressure of the combined speed regulator (when the speed regulator is working, the oil pressure in the oil storage chamber is 640-686kPa) to drive the oil to circulate between the oil heater and the speed regulator. The oil heater heats the oil, and the test can be carried out when the oil temperature reaches the test temperature.

[0015] See Figure 1 and Figure 2 The utility model primarily comprises an oil heater 3 and two 5mm diameter hoses 2. The oil heater 3 comprises a heating tape 5, a metal tube 4 with a diameter of 4-8mm and a length of 200mm, and a protective cover 7. The heating tape 5 is attached to the metal tube 4. One end of the two hoses 2 is connected to the ends of the metal tube 4, and the other ends of the two hoses 2 are connected to the oil filling port and oil drain port of the combined speed regulator, forming a circulating oil circuit. Protecting the metal tube 4 with the heating tape 5 attached and the protective cover 7 heats the oil inside the speed regulator.

[0016] The inner wall of the protective cover 7 is provided with a heat-insulating layer 6 to reduce heat loss and lower energy consumption.

[0017] The metal tube 4 is made of copper to improve thermal conductivity.

[0021] When testing a combined speed governor on a diesel locomotive, first connect the two hoses 2 of the present invention to the oil filling port and oil drain port of the combined speed governor, respectively. Then, use a laboratory drive device (usually a motor) to drive the combined speed governor to operate, so that the oil circulates between the oil heater 3 and the combined speed governor 1. At the same time, the heating belt 5 is energized to heat the oil flowing through the metal tube 4 in the oil heater 3. During the heating process, the oil temperature is monitored in real time with a thermometer. When the oil temperature reaches the test temperature, the test can be carried out.
