Description

A cleaning device for servo hydraulic station

Technical Field

The utility model relates to the technical field of cleaning of a servo hydraulic station, in particular to a cleaning device for a servo hydraulic station.

Background Art

The servo hydraulic station equipment is mainly used to control the hydraulic system. It is composed of control valves, hydraulic pumps, pressure sensors, servo valves, etc. It has been rapidly developed due to its high safety, high precision, environmental protection, efficiency improvement and cost reduction. When the servo hydraulic station is used for a long time, the outer shell of the servo hydraulic station will be contaminated with dust and some oil stains, so the servo hydraulic station needs to be cleaned with a cleaning device.

When the servo hydraulic station in the prior art is used for a long time, the outer shell of the servo hydraulic station will be contaminated with dust and some oil stains. The dust and oil stains not only affect the appearance, but also easily block the heat dissipation channel of the servo hydraulic station. In addition, the dust and oil stains may enter the electrical equipment of the servo hydraulic station, such as the control panel, power socket, etc., thereby causing electrical failure or short circuit, resulting in safety accidents. For this reason, the outer shell of the servo hydraulic station needs to be cleaned regularly. However, the dust and oil stains on the outer shell of the servo hydraulic station are mostly cleaned manually using a cleaning brush. Because manual cleaning is more laborious, when large quantities are required for cleaning, it is not only too time-consuming, but also has low work efficiency. In addition, when manual cleaning is carried out for a long time, the manual arm may become weak, resulting in cleaning tools or cleaning agents falling onto the servo hydraulic station, causing damage to the servo hydraulic station.

In view of the above technical problems, this application proposes a solution.
