And a place for corrosive metals and the destruction of an insulated gas;

6、在有防雨雪設備和沒有充滿水蒸氣的地方。

6, in the rain and snow prevention equipment and not a place full of steam.

二、型號含義

Two, model meaning

三、結構及工作原理

Three, structure and working principle

推動器主要由三部分組成：電動機、液壓泵和液壓缸。電動機軸是空心的，通過聯軸節與方軸聯結，方

The drive is mainly composed of three parts: motor, hydraulic pump and hydraulic cylinder. The motor shaft is hollow, through the coupling and shaft coupling, Party

軸端部裝離心葉輪。當推桿動作時，方軸在空心的電動機軸中上下滑動，傳遞扭矩。

Shaft end centrifugal impeller. When the push rod moves, the square shaft of the motor shaft in the hollow of the upper and lower sliding, transmission torque.

當電動機通電時，帶動葉輪旋轉，將油液強行壓入活塞底部，迫使活塞上升，帶動推桿上升。斷電時，

When the motor through power, to drive the impeller to rotate, the oil will be forced into the bottom of the piston, forcing the piston to rise, driven by the rise of the push rod. Power down,

葉輪停止旋轉，活塞在自身重力或彈簧力的作用下恢復原位。

The impeller stops rotating, and the piston is restored in situ under the action of gravity or spring force.

四、技術數據（表2）及外形尺寸（表3、表4）

Four, technical data (Table 2) and outline dimensions (Table 3, table 4)

五、安裝使用和維修

Five, installation and maintenance

1、推動器的安裝外形尺寸見圖及表3、表4

1, the installation of the driver of the size of the installation and table 3, table 4

2、使用前檢查推動器銘牌上技術數據是否與所需技術數據相符合。

2, before use to check drive nameplate on the technical data and required technical data is consistent.

3、使用推動器前，應清除推動器外表油垢，然后從蓋上注油孔注入符合下表1的油液。接通電源，檢查葉輪是否靈活轉動，推桿及活塞是否有卡滯現象。

3, the use of push, push the grease should be removed from the appearance, and then cover the oil hole injection according to the following table oil 1. Turn on the power, check whether the impeller is flexible rotation, putting and whether there is a card hysteresis phenomenon.

4、在安裝制動器時，將推動器下部安裝孔連接于制動器基座上，連桿與制動器角杠桿連接。

4. When the brake is installed, the lower part of the drive device is connected to the brake base, and the connecting rod and the brake angle are connected.

5、將電動機的引出線于外部電源連接。

5, the electric motor of the lead wire in the external power connection.

6、推動器在使用時應注意：

6, the driver should pay attention to the use of:

（1）定期加油；

(1) regular refueling;

（2）注意油的清潔，在必要時更換油液；

(2) note that the oil is cleaned and replaced when necessary;

（3）葉輪旋轉是否靈活；

(3) the impeller rotation is flexible;
