AI Technical Summary

Technical Problem

Existing hydraulic cooling devices cannot quickly and automatically switch cooling modes according to oil temperature changes under extreme environments or prolonged high loads, resulting in unsatisfactory cooling effects and failing to meet the temperature requirements of drilling rigs under different operating conditions.

Method used

An automated hydraulic station cooling device was designed, which adopts a combination of air cooling and water cooling system. The cooling mode is automatically switched through control valves and bimetallic strips. The cooling path is adjusted in real time according to the hydraulic oil temperature to ensure that the oil temperature is within a suitable range.

Benefits of technology

It achieves precise control of hydraulic oil temperature, improves cooling efficiency, reduces the risk of wear on hydraulic components and the probability of oil oxidation and deterioration, and extends the service life of hydraulic oil.

Abstract

This invention relates to the field of hydraulic oil cooling technology, and in particular to a cooling device for a hydraulic power station of automated machinery. The device includes an oil tank, an oil outlet pipe installed on the outer wall of the tank, a filter assembly installed on the oil outlet pipe, a circulating oil pump fixedly installed at the outlet end of the oil outlet pipe, a first cooling pipe fixedly installed at the outlet end of the circulating oil pump, and a second cooling pipe fixedly installed at the outlet end of the first cooling pipe, the outlet end of the second cooling pipe being fixedly connected to the oil tank. A control valve is installed between the first and second cooling pipes, and the control valve is connected to the first cooling pipe, the second cooling pipe, and the oil tank. An air-cooling system is fixedly installed at the front end of the oil tank, and the first cooling pipe is coiled inside the air-cooling system. This invention can automatically switch to water cooling if the actual oil temperature is insufficient, ensuring that the hydraulic oil is always within a suitable temperature range, greatly improving the overall cooling efficiency.
