DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0025] The utility model aims to provide an intelligent oil source device which can control the lubricating oil temperature within a range of 5°C and is suitable for the on-site conditions of the route and has a mobile function.

[0026] Please refer to Figure 1 and Figure 2 The utility model provides a temperature-controllable mobile oil source device, comprising an oil tank 1, a heating mechanism 2, an oil supply mechanism 3, a cooling mechanism 4 and an oil return mechanism 5;

[0028] The oil supply mechanism 3 includes an oil supply pump 31, an oil inlet pipe 32 and a first temperature measuring element 38. The inlet of the oil supply pump 31 is connected to the oil tank 1, and the outlet of the oil supply pump 31 is connected to the inlet of the product 6 to be tested via the oil inlet pipe 32. The first temperature measuring element 38 is connected to the oil inlet pipe 32 and is used to detect the temperature of the lubricating oil in the oil inlet pipe 32. In this embodiment, the first temperature measuring element 38 is a first platinum thermal resistor.

[0029] The cooling mechanism 4 is connected to the oil inlet pipe 32 and is used to cool the lubricating oil in the oil inlet pipe 32;

[0030] The oil return mechanism 5 includes an oil return pump 51 , and an inlet and an outlet of the oil return pump 51 are respectively connected to the outlet of the tested product 6 and the oil tank 1 .

[0031] When in use, the oil inlet pipe 32 is connected to the inlet of the product under test 6, and the inlet of the return oil pump 51 is connected to the outlet of the product under test 6. The lubricating oil in the oil tank 1 is heated by the heating mechanism 2. When the lubricating oil in the oil tank 1 reaches the set temperature, the oil supply pump 31 is turned on, and the lubricating oil in the oil tank 1 enters the product under test 6 through the oil inlet pipe 32. The return oil pump 51 is turned on again, and the lubricating oil in the product under test 6 is sucked into the oil tank 1 by the return oil pump 51, forming a cycle. During this process, the temperature of the lubricating oil in the oil inlet pipe 32 is continuously detected by the first temperature measuring component 38. When the temperature of the lubricating oil exceeds a preset temperature, the temperature of the lubricating oil in the oil inlet pipe 32 is cooled by the cooling mechanism 4. When the temperature of the lubricating oil is lower than a preset temperature, the lubricating oil in the oil tank 1 is heated by the heating mechanism 2, so that the temperature of the lubricating oil entering the product under test 6 can be kept stable, thereby meeting the detection requirements of the product under test 6.

[0032] In order to realize the function of the heating mechanism 2, please refer to Figure 1 and Figure 2In a preferred embodiment, the heating mechanism 2 includes a heating oil pump 21 and a pipeline heater 22. The inlet of the heating oil pump 21 is connected to the oil tank 1, the outlet of the heating oil pump 21 is connected to the inlet of the pipeline heater 22, and the outlet of the pipeline heater 22 is connected to the oil tank 1. When the lubricating oil in the oil tank 1 needs to be heated, the heating oil pump 21 and the pipeline heater 22 are turned on, and the lubricating oil in the oil tank 1 enters the pipeline heater 22 through the heating oil pump 21, and is heated to a certain temperature in the pipeline heater 22 and then discharged back to the oil tank 1. In this embodiment, the heating mechanism 2 also includes a variable frequency motor 23, and the variable frequency motor 23 is used to drive the heating oil pump 21.

[0033] In this embodiment, in order to prevent the carbonization of the product lubricating oil, a pipeline heater 22 is used to heat the oil. The pipeline heater 22 is composed of several parts such as multiple tubular electric heating elements, a cylinder, and a guide plate. The tubular electric heating element is a high-temperature resistance wire placed in a metal tube, and the gap is tightly filled with crystalline magnesium oxide powder with good insulation and thermal conductivity. The tubular electric heating element is used as a heating element, which has the characteristics of advanced structure, high thermal efficiency, good mechanical strength, corrosion resistance, and wear resistance. A guide baffle is installed in the cylinder to ensure that the oil is heated evenly during circulation. It is ensured that the working fluid in the pipeline heater has a large unit contact area, high heat exchange efficiency, and a large temperature rise at the inlet and outlet of the heater, so that the product inlet temperature can reach the required temperature earlier without waiting for a large amount of working fluid in the oil tank to reach the set temperature at the same time. Since the oil in the pipeline has a fast flow rate and a short contact time with the heating device, the oil will not be overheated and it is not easy to generate carbon deposits during heat exchange. The pipeline heater uses a temperature regulator, a solid-state relay and a temperature measuring element to form a measurement, regulation and control loop. Through the PID control algorithm, during the electric heating process of the pipeline heater, the temperature measuring element sends the outlet temperature electrical signal of the pipeline heater to the temperature regulator for amplification, and displays the measured temperature value of the pipeline heater after comparison. At the same time, the signal is output to the input end of the solid-state relay, thereby controlling the working power of the heater, so that the pipeline heater has good control accuracy and regulation characteristics. The specific structure of the pipeline heater is the prior art, and the utility model will not repeat it.
