Technical Field
[0001] This utility model belongs to the field of hydraulic oil tank temperature control technology, specifically relating to a constant temperature control device for hydraulic oil tanks of dynamometers. Background Technology
[0002] A lubrication system is essential for the operation of a dynamometer. The temperature of the lubricating oil is generally the same as the room temperature before use, while the operating temperature of most lubricating oils is above 90°C. In existing technology, the equipment is usually idled for a certain period of time to raise the temperature of the lubricating oil to a suitable level before the equipment is put under load. In this process, the oil temperature rises slowly, and the waiting time is long, which not only wastes time but also wastes energy during machine operation. There is an urgent need for a method to solve this problem. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0019] The following detailed description of the specific embodiments of this utility model, in conjunction with the accompanying drawings, further illustrates the following: A constant temperature control device for a hydraulic oil tank of a dynamometer includes a housing 1, a protective cover 2, a circulating pump 3, and a heater 4. The housing 1 is a rectangular housing with an opening at the top, and a top cover 9 is provided on the upper surface of the housing 1. The top cover 9 is to prevent foreign objects from entering the interior of the housing 1, and the hydraulic oil pipeline connecting the housing 1 to the dynamometer can also be installed on the top cover 9. Hydraulic oil 8 is provided inside the housing 1, and a protective cover 2 is provided at the center of the bottom surface of the housing 1. The protective cover 2 has openings at both the left and right ends, and a circulating pump 3 and a heater 4 are provided inside the protective cover 2. The left opening of the protective cover 2 is the oil inlet, and the right opening is the oil outlet. The circulating pump 3 is located to the left of the heater 4. In this embodiment, the circulating pump 3 is an adjustable power oil pump, and the power of the heater 4 is adjustable. Adjusting the power of the circulating pump 3 also adjusts the flow rate of the oil. Adjusting the power of the heater 4 adjusts the temperature of the oil. The upper left and right end faces of the housing 1 are provided with upper guide plates 5, the lower left and right end faces of the housing 1 are provided with middle guide plates 6, and the four corners of the bottom surface of the housing 1 are provided with lower guide plates 7; the upper guide plate 5 is a right-angled triangular prism, the right-angled side of the upper guide plate 5 is connected to the side of the housing 1, and the inclined surface of the upper guide plate 5 is provided with an arc-shaped groove; the upper end face of the upper guide plate 5 is lower than the hydraulic oil 8 level; the upper guide plate 5 is used for oil flow guidance, allowing the upper end of the oil to flow towards the oil inlet; the middle guide plate 6 is a triangular pyramid structure, the middle guide plate... The bottom surface of the middle guide plate 6 is connected to the bottom surface of the housing 1, and the side surface of the middle guide plate 6 is connected to the side surface of the housing 1. The two sides of the middle guide plate 6 are provided with arc-shaped grooves, and the axis of symmetry of the middle guide plate 6 is collinear with the axis of symmetry of the protective cover 2. The center of the middle guide plate 6 is directly opposite the oil outlet. The middle guide plate 6 facilitates the diversion of oil to both ends and the top, which is beneficial to the flow of oil. The lower guide plate 7 is a right-angled triangular pyramid, and the inclined surface of the lower guide plate 7 is provided with arc-shaped grooves. The lower guide plate 7 facilitates the diversion of oil to the oil inlet and the top, which is beneficial to the flow of oil.
[0020] The usage process of this utility model is as follows: First, assemble the hydraulic oil tank; then install the oil pipe connected to the hydraulic oil tank on the upper cover 9 or the side wall of the tank body 1; when using this hydraulic oil tank, first, turn on the circulation pump 3 and the heater 4 to preheat the oil; at this time, the circulation pump 3 draws the oil from the oil inlet and discharges it to the heater 4. When the oil passes through the heater 4, it is heated, and the heated oil is discharged from the oil outlet. After being discharged, the oil rushes towards the middle guide plate 6 at the front end of the oil outlet. Under the action of the middle guide plate 6, a portion of the oil is diverted from the left and right ends and flows towards the oil inlet. During the flow, because the temperature of the oil is higher than that of the oil at the upper end, the oil will flow upward and meet the upper... The oil at one end mixes with the other; the other part of the oil flows upward, mixes with the oil at the upper guide plate 5, and flows towards the oil inlet; during this process, the flow rate and heating rate of the oil can be adjusted by adjusting the power of the circulation pump 3 and the heater 4; when the oil temperature reaches the required level, the equipment connected to the hydraulic oil tank is turned on, and the oil circulation is started; at this time, the oil in the tank enters the external equipment and carries the oil from the external equipment back into the tank. By observing the change in the oil temperature in the tank, the circulation pump 3 and the heater 4 are adjusted to stabilize the temperature in the tank; when the external equipment stops running, the external equipment is turned off, and then the circulation pump 3 and the heater 4 are turned off, waiting for the next use.
