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

二、型号含义

Two, model meaning

三、结构及工作原理

Three, structure and working principle

推动器主要由三部分组成：电动机、液压泵和液压缸。电动机轴是空心的，通过联轴节与方轴联结，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

轴端部装离心叶轮。当推杆动作时，方轴在空心的电动机轴中上下滑动，传递扭矩。

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.

当电动机通电时，带动叶轮旋转，将油液强行压入活塞底部，迫使活塞上升，带动推杆上升。断电时，

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,

叶轮停止旋转，活塞在自身重力或弹簧力的作用下恢复原位。

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

四、技术数据（表2）及外形尺寸（表3、表4）

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

五、安装使用和维修

Five, installation and maintenance

1、推动器的安装外形尺寸见图及表3、表4

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

2、使用前检查推动器铭牌上技术数据是否与所需技术数据相符合。

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

3、使用推动器前，应清除推动器外表油垢，然后从盖上注油孔注入符合下表1的油液。接通电源，检查叶轮是否灵活转动，推杆及活塞是否有卡滞现象。

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、在安装制动器时，将推动器下部安装孔连接于制动器基座上，连杆与制动器角杠杆连接。

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、将电动机的引出线于外部电源连接。

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

6、推动器在使用时应注意：

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

（1）定期加油；

(1) regular refueling;

（2）注意油的清洁，在必要时更换油液；

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

（3）叶轮旋转是否灵活；

(3) the impeller rotation is flexible;
