Description

Technical Field

[0001] The utility model relates to the technical field of temperature control of oil coolers, in particular to a temperature control device for automatically controlling an oil cooler. Background Technique

[0002] The lubricating oil system is an oil supply system used to provide forced lubricating oil for equipment such as compressors, drivers, speed changers, and couplings, and to provide regulating oil for steam turbines. The lubricating oil system consists of a lubricating oil station, a high-level oil tank, intermediate connecting pipelines, and various control valves and instruments. The lubricating oil in the lubricating oil system is cooled by an oil cooler, and the temperature of the cooled lubricating oil is regulated by a temperature control device in the oil cooler. Some temperature control devices for oil coolers include a chevron three-way pipe. The two inlets of the chevron three-way pipe are connected in parallel between the inlet and outlet of the oil cooler through a connecting pipeline. Control valves are serially connected in the middle of the connecting pipeline. By mixing some uncooled lubricating oil and some lubricating oil cooled by the oil cooler and flowing through the chevron three-way pipe, the temperatures of the two kinds of lubricating oil with different temperatures are neutralized and changed with each other. The flow rates of the uncooled lubricating oil and the lubricating oil cooled by the oil cooler are proportionally regulated through the control valves respectively, so as to realize the regulation of the output temperature of the lubricating oil of the oil cooler. However, when the device regulates the temperature of the lubricating oil of the oil cooler, the staff needs to manually adjust the opening and closing degree of the control valve. Manually adjusting the control valve by the staff cannot ensure that the temperature of the lubricating oil output by the oil cooler reaches the temperature value required by the corresponding demand, and the automation degree of the device is relatively low.

Flange plates 4 are provided at both the left and right ends and the lower end of the temperature control housing 1. Rubber sealing rings 5 are provided on the sides of the flange plates 4 away from the center of the temperature control housing 1. A partition plate 6 is installed inside the temperature control housing 1. A converging ring 10 is provided at the lower end inside the temperature control output groove 15. The converging ring 10 is installed in cooperation with the temperature sensor 11. Temperature sensors 12 are installed at both the left and right ends of the upper side of the temperature control housing 1. The temperature sensors 12 are both bidirectionally electrically connected to the single-chip microcomputer 2. When using the device to regulate the temperature of the lubricating oil output by the cold oil cooler, first, the upper end of the device is connected in parallel to the cold oil cooler inlet and outlet through the corresponding flange plates 4 with bolts. The normal temperature drainage groove 13 is communicated with the cold oil cooler inlet, and the cooling drainage groove 14 is communicated with the cold oil cooler outlet. The rubber sealing ring 5 is used to improve the sealing performance of the pipeline connection part of the device. Subsequently, the single-chip microcomputer 2 starts the temperature sensors 12 to respectively detect the temperature of the lubricating oil at the corresponding cold oil cooler inlet and outlet parts, and transmits the detection results to the single-chip microcomputer 2 in the form of electrical signals. When regulating the temperature of the lubricating oil output by the cold oil cooler, the temperature-bearing lubricating oil flowing out of the normal temperature drainage groove 13 and the lubricating oil cooled by the cold oil cooler flowing out of the cooling drainage groove 14 enter the temperature control output groove 15. During the mixing process of the two kinds of lubricating oil with different temperatures, temperature regulation is carried out through contact heat transfer and then output. At the same time, the single-chip microcomputer 2 starts the temperature sensor 11 to detect the temperature of the lubricating oil output by the temperature control in the converging ring 10 and transmits the detection results to the single-chip microcomputer 2 in the form of electrical signals. The single-chip microcomputer 2 controls the corresponding electric control valve 3 according to the measured results to adjust the lubricating oil flow cross-section areas of the normal temperature drainage groove 13 and the cooling drainage groove 14, and then realizes the automatic regulation of the temperature of the lubricating oil output by the cold oil cooler by adjusting the flow rates of the two kinds of lubricating oil with different temperatures in different proportions. It is convenient to use. The partition plate 6 is used to prevent the lubricating oil in the normal temperature drainage groove 13 and the cooling drainage groove 14 from flowing into each other. This temperature control device for automatically controlling a cold oil cooler can accurately regulate the temperature of the lubricating oil output by the cold oil cooler automatically through detection elements and electric elements, and is convenient to use;

[0022] Among them: It also includes a single-chip microcomputer 2, which is installed on the outer side of the temperature control shell 1 through a connecting frame. The input end of the single-chip microcomputer 2 is electrically connected to an external power supply, the output end of the single-chip microcomputer 2 is respectively electrically connected to the input end of the electric control valve 3, and the single-chip microcomputer 2 is bidirectionally electrically connected to the first temperature sensor 11, which is convenient for controlling electrical components;

[0023] Among them, a cross 7 is arranged inside the temperature control output groove 15. A fixed shaft 8 is arranged on the upper side of the cross 7, and evenly distributed guide fan blades 9 are arranged on the outer side of the fixed shaft 8. After the lubricating oil of two temperatures, hot and cold, enters the temperature control output groove 15, due to the flow pressure of the lubricating oil, the guide fan blades 9 are pressed to rotate. Through the rotation of the guide fan blades 9, the lubricating oil of two temperatures, hot and cold, rotates and blends with each other during the movement, so that the hot and cold lubricating oils are in full contact for heat exchange, thereby improving the accuracy of the temperature detection of the lubricating oil output by the temperature sensor 11 itself for temperature control, and facilitating the device to accurately control the temperature of the lubricating oil output by the cooler. For this temperature control device of the automatic control oil cooler, the hot and cold lubricating oils are spirally blended and heat transferred through the guiding element, improving the accuracy of the device for detecting the temperature of the lubricating oil output by the oil cooler.

[0024] The working principle of a temperature control device for automatically controlling a cold oil cooler provided by the present utility model is as follows: When using the device to regulate the temperature of the lubricating oil output by the cold oil cooler, first, the upper end of the device is connected in parallel to the inlet and outlet of the cold oil cooler through the corresponding flange 4 with bolts. The normal temperature drainage groove 13 is connected to the inlet of the cold oil cooler, and the cooling drainage groove 14 is connected to the outlet of the cold oil cooler. The rubber sealing ring 5 is used to improve the sealing performance of the pipeline connection part of the device. Subsequently, the single-chip microcomputer 2 starts the temperature sensor two 12 to detect the temperatures of the lubricating oil at the corresponding inlet and outlet parts of the cold oil cooler respectively, and transmits the detection results to the single-chip microcomputer 2 in the form of electrical signals. When regulating the temperature of the lubricating oil output by the cold oil cooler, the lubricating oil with temperature flowing out of the normal temperature drainage groove 13 and the lubricating oil cooled by the cold oil cooler flowing out of the cooling drainage groove 14 enter the temperature control output groove 15. During the mixing process of the lubricating oils at two different temperatures, temperature regulation is carried out through contact heat transfer and then output. At the same time, the single-chip microcomputer 2 starts the temperature sensor one 11 to detect the temperature of the lubricating oil output by the temperature control in the gathering ring 10 and transmits the detection results to the single-chip microcomputer 2 in the form of electrical signals. The single-chip microcomputer 2 controls the corresponding electric control valve 3 according to the measured results to adjust the cross-sectional areas of the lubricating oil flowing through the normal temperature drainage groove 13 and the cooling drainage groove 14, and further adjusts the flow rates of the lubricating oils at two different temperatures in different proportions, so as to realize the automatic regulation of the temperature of the lubricating oil output by the cold oil cooler. It is convenient to use. The partition plate 6 is used to prevent the mutual flow of the lubricating oils in the normal temperature drainage groove 13 and the cooling drainage groove 14. At the same time, after the lubricating oils at two different temperatures enter the temperature control output groove 15, due to the flow pressure of the lubricating oil, the guide fan blade 9 is pressed to rotate. Through the rotation of the guide fan blade 9, the lubricating oils at two different temperatures rotate and blend with each other during the movement, so that the lubricating oils at two different temperatures can fully conduct contact heat exchange, and further improve the accuracy of the temperature detection of the lubricating oil output by the temperature control by the temperature sensor one 11, which is convenient for the device to accurately regulate the temperature of the lubricating oil output by the cooler.
