hydraulic hatch cover的意思|示意

Hydraulic hatch cover is an important part of a ship which plays an important role in cargo storage.

用途：

Hydraulic hatch cover is mainly used to open, close and seal the opening on the hull. This allows the cargo to be loaded and unloaded, while ensuring the cargo hold is watertight.

结构：

Hydraulic hatch cover usually consists of a steel frame, hinges, locking cleats, stop dogs, and a cover plate. The cover plate can be a single piece or multiple pieces depending on the size and shape of the hatch opening. The cover plate is usually made of steel, but can be made of other materials such as aluminum or fiberglass.

操作：

The operation of the hydraulic hatch cover is usually done by a hydraulic system. Hydraulic pressure is used to open and close the hatch cover, and to keep it in place when it is closed. The hydraulic system also provides the power to lock the hatch cover in place when it is closed.

The hydraulic pressure is supplied by a hydraulic pump, which is powered by either an electric motor or an engine. The hydraulic pump is controlled by a control unit, which is typically located in the wheelhouse.

使用：

Hydraulic hatch covers are used in a wide variety of marine applications. They are commonly used on tankers, cargo ships, and supply vessels. They are also used for loading and unloading of cargo containers and other large items.

Hydraulic hatch covers provide an effective seal to keep the cargo hold watertight. This ensures that the cargo is protected from the elements while being stored and transported.
