产品简介 Product Profile  

 HYC-EHA系列电动静液作动器，是一种集成了伺服电机、 双向柱塞泵（进出油方向可逆）、阀组、执行机构（油缸或马达）、以及油箱、过滤器、传感器等辅助元件的成套静液传动装置。采用泵控容积调速，通过改变伺服电机旋向和转速来调节执行机构运行方向和运行速度。

    HYC-EHA series Electro-Hydrostatic Actuator is a complete set of hydrostatic transmission device  that integrates servo motor, bidirectional pump, valves, and auxiliary components such as tank, filters and sensors. With the characteristics of pump-controlled volume speed regulation, the actuator can be manipulated by adjusting rotation direction and speed of servo motor.

 EHA将液压系统的动力元件、控制元件、执行元件和辅助元件集成一体，安装布局灵活，使用便利。

     EHA integrates power components, control components, actuators and auxiliary components of  the hydraulic system, making it flexible in installation layout and easy to use.

 EHA通常采用闭式回路，根据具体使用需求，也可以设计为开式回路或半开式回路。

    EHA is usually designed with a closed circuit, and may also be an open or semi-open circuit according to the specific needs.

 本公司研制的四象限高压柱塞泵，尤其适用于EHA。

    The four-quadrant high pressure piston pump developed by our company is especially suitable for EHA.

 本公司为EHA研制的溢流&平衡阀，在提升EHA工作性能的同时，大幅简化液压回路，集成阀块外形体积更小，重量更轻。

    The relief & counterbalance valve developed by our company for EHA can dramatically simplify the hydraulic circuit while improving the working performance of EHA. The integrated valve block is smaller in shape and lighter in weight.

 本公司为EHA研制的流量匹配阀，适用于执行机构为非对称油缸的应用需求。该阀标准产品为板式安装，也可内嵌于泵的端盖内部，有效提高EHA集成化程度。

   The flow-matching valve developed by our company for EHA is suitable for applications where the actuator is an asymmetric cylinder. The standard product of the valve is plate-mounted, and it can also be embedded in the pump to effectively improve the integration degree of EHA.

 EHA通常采用封闭式弹性油箱，以便EHA可工作于任意姿态。根据具体使用要求，可选择采用活塞式增压油箱，或气囊式增压/常压油箱。

    EHA is usually designed with a closed elastic tank so that it can work in any posture. According to the specific requirements, you can choose to use piston-type pressurized tank or bag-type pressurized/atmospheric-pressure tank.

 当应用环境为深海时，本公司可为EHA配置水压补偿器，使EHA内部压力与外部水压实时匹配。

    When applied to the deep sea, the EHA can be configured with a water pressure compensator, so that the internal pressure of the EHA is matched with the external pressure in real time.

 必要时本公司可为EHA研制专用的液压阀，以实现特殊功能需求或特殊安装需求。

    If necessary, our company can develop special hydraulic valves for EHA to meet particular requirements.

 不同用途的EHA，具体功能配置要求一般也不同，故EHA通常为定制产品，选型前请与本公司进行技术沟通。

    Generally, the specific configuration parameters of EHA varies when for different purposes, so EHA is usually a customized product. Please communicate with our company before selection.

    型号说明 Type Explanation

①EHA的液压动力源可以单独供货，此时产品型号不再包含执行机构参数，写成“HYC-EHA.PS1kW-*”的形式。  

    The EHA hydraulic power source can be supplied separately, and the product type no longer contains the actuator parameters, which would be written in the form of "HYC-EHA.PS1kW-*".

②由于应用需求的多样性，基本型号相同的EHA在具体功能和配置上可能存在较大的差异，通常需要在基本型号后增加定制代号以便于区分。如果用户没有指定，则定制代号为本公司设计代号。 

    Due to the diversity of application requirements, EHA with the same basic model may have large differences in specific functions and configurations, so ususlly it is necessary to add a custom code for distinction. If the client does not specify, the custom code would be designed by the company.

 在必要时，本公司可能对产品型号编制规则进行修订，订货前请与本公司确认。

If necessary, the company may revise the naming rules of product model.  Please confirm with the company before ordering.

EHA典型液压回路 Typical Circuit of EHA

执行机构为双作用对称油缸 The actuator is a double-acting symmetrical cylinder

执行机构为双作用非对称缸 The actuator is a double-acting asymmetric cylinder

执行机构为带弹簧复位的单作用缸 The actuator is a single-acting cylinder with a spring-return device

执行机构为自由浮动的单作用缸 The actuator is a floating single-acting cylinder

对于响应要求较高的应用场合，执行机构优选双作用对称油缸。 

For applications with high response requirements, the actuator will be preferentially selected as a double-acting symmetrical cylinder.

此处所列EHA典型液压回路，仅用于表达EHA工作原理，实际产品的液压回路根据具体使用需求而设计。
