Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil pumps, in particular to a hydraulic oil pump temperature monitoring and self-cooling component. Background Art

[0002] As the core power source in the hydraulic system, the hydraulic oil pump is mainly composed of key components such as the pump body, rectangular oil tank, pressure handle and ultra-high pressure steel wire braided hose. These components work together to effectively convert the mechanical energy of the prime mover into the pressure energy of the liquid, providing power for the entire hydraulic system. In terms of the types of hydraulic pumps, common ones are gear pumps, vane pumps and plunger pumps, each of which is suitable for different working environments and needs due to its unique design and working principle. Although the design and function of the hydraulic oil pump are quite mature in current applications, it transfers heat to the hydraulic oil during operation, causing the hydraulic oil temperature to rise, thereby increasing the heat dissipation burden at the hydraulic oil tank.

[0003] The patent with publication number CN216589086U discloses a high-pressure hydraulic oil pump, including a hydraulic oil pump housing, an end cover is installed at the front end of the hydraulic oil pump housing, an oil inlet is arranged on one side of the hydraulic oil pump housing, and an oil outlet is arranged on the other side of the hydraulic oil pump housing, the inner lower end of the hydraulic oil pump housing is rotatably connected with a driving shaft, a driving gear is fixedly sleeved on the driving shaft, one end of the driving shaft extends to the outside of the end cover and a spline is arranged on the outer wall, the heat of the hydraulic oil circulating in the hydraulic oil pump housing is absorbed by the heat-conducting inner sleeve plate, and is conducted to the heat sink, and the heat is quickly dissipated by the multiple groups of heat sinks, thereby improving the heat dissipation effect, and the heat sink fan is driven to rotate by the driven shaft, and the air outlet direction of the heat sink fan is toward the hydraulic oil pump housing, and the heat dissipated by the heat sink can be quickly taken away by the flowing wind, thereby further improving the heat dissipation effect.

[0004] In the specific use of the above-mentioned prior art, since the heat dissipation fan is located on one side of the hydraulic oil pump housing, the airflow generated by the heat dissipation fan is all directed toward one side of the hydraulic oil pump housing, and the airflow is dispersed under the blocking effect of the side of the hydraulic oil pump housing, which makes it difficult for the airflow to pass through multiple heat sinks, and it is difficult to play an auxiliary heat dissipation role for the heat sink, and the heat dissipation fan works synchronously with the hydraulic oil pump, and the driving shaft drives the driving gear to rotate, and the driving gear drives the driven gear to rotate, so that the driven gear drives the driven shaft to rotate, and the driven shaft drives the heat dissipation fan to rotate, which will increase the energy consumption of the hydraulic oil pump and also increase the heat generation of the hydraulic oil pump. In view of this, we propose a hydraulic oil pump temperature monitoring and self-cooling component. Utility Model Content

The fan generates airflow in the I-shaped hollow plate, and the airflow is output from the strip-shaped air outlet, thereby blowing and cooling the surface of the heat sink and the hydraulic oil pump body until the temperature sensor detects that the temperature on the surface of the hydraulic oil pump body is lower than the set threshold, and the controller controls the fan to stop to reduce energy consumption.
