Hydraulic Systems Components

油圧システムのコンポーネント

Virtually, all-hydraulic circuits are essentially the same regardless of the application.

事実上、すべての油圧回路は、アプリケーションに関わらず、本質的に同じです。

There are six basic components required for setting up a hydraulic system:


油圧システムをセットアップするために必要な6つの基本コンポーネントがあります。

A reservoir to hold the liquid (usually hydraulic oil)

1。液体を保持するリザーバ（通常は油圧オイル）

A pump to force the liquid through the system

2。システムを介して液体を強制的に押し出すポンプ

An electric motor or other power source to drive the pump
3。ポンプを駆動する電気モーターやその他の動力源

Valves to control the liquid direction, pressure and flow rate
4。液体方向、圧力と流量を制御するバルブ
An actuator to convert the energy of the liquid into mechanical force or torque, to do useful work.

5。液体のエネルギーを機械的な力またはトルクに変換するアクチュエータ、有用な作業を行う。
Actuators can either be cylinders which provide linear motion or motors which provide rotary motion and

リニア運動を提供シリンダする又は
回転運動するモータのいずれかのアクチュエータである

Piping to convey the liquid from one location to another.

6。ある場所から別の場所に液体を伝えるために配管。


Figure 9.1 illustrates the essential features of a basic hydraulic system with a linear hydraulic actuator.

図9.1は、リニア油圧アクチュエータの基本的な油圧システムの本質的な特徴を示しています。

The extent of sophistication and complexity of hydraulic systems vary depending on the specific application.

油圧システムの高度化と複雑さの程度は、特定のアプリケーションによって異なります。

Each unit is a complete packaged power system containing its own electric motor, pump, shaft coupling, reservoir and miscellaneous piping, pressure gauges, valves and other components required for operation.
各ユニットは、独自の電気モーター、ポンプ、シャフトカップリング、貯水池およびその他の配管、圧力計、バルブと操作に必要なその他のコンポーネントを含む完全なパッケージ電源システムです。
