Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic stations, in particular to a hydraulic station for a well drilling and workover machine. Background Art

[0002] As the core power and control system of the drilling and servicing rig, the hydraulic station is responsible for converting mechanical energy into hydraulic energy, and providing power to various actuators (such as motors, hydraulic cylinders, etc.) of the drilling and servicing rig through the hydraulic transmission system to realize the rotation, feeding, lifting and other functions of the drilling rig. In addition, the hydraulic station is suitable for various industrial equipment; however, most of the existing hydraulic stations are fixed and the hydraulic stations are heavy and inconvenient to move. Once the use position of the hydraulic station is fixed, it will not be moved. It is inconvenient to connect some hydraulic oil pipelines, and it is necessary to re-pipe or move the hydraulic station, which is inconvenient to use.

[0003] The Chinese patent discloses a new hydraulic station (authorization announcement number CN212107728U). The patented technology can facilitate the movement of the hydraulic station by adding universal wheels and bearings. The position of the hydraulic station can be moved at will through the universal wheels, which is convenient for the use of the hydraulic station. At the same time, the hydraulic station can be rotated at will to facilitate the connection of the pipeline, avoiding the need to reconnect the pipeline when the hydraulic station is inconvenient to move, and the pipeline can be quickly connected to the hydraulic station, which is convenient for connection and use; by adding a motor and a fan blade to dissipate heat inside the main body, especially the oil tank inside the main body, it is prevented from overheating the hydraulic oil and affecting the normal operation of the hydraulic oil, ensuring the reliable and effective operation of the hydraulic station, and adding a ventilation hood to prevent foreign matter from entering the main body and affecting the components inside the main body, and to prevent the fan blades from causing harm to the operator;

[0004] However, it has certain drawbacks: although its ventilation hood can prevent foreign matter from entering the interior of the main body, it cannot absorb moisture in the air, so it cannot prevent water vapor from entering the interior of the main body. The moisture in the air can easily condense on the surface of the equipment or penetrate into the interior of the equipment, causing circuit short circuits, rust on metal parts and other problems, thereby accelerating the aging and damage of the equipment.
