Filtration Group hydraulic filters in mobile cranes/KE 2900

过滤集团液压过滤器移动式起重机上的应用/KE2900

Almost every function in a mobile crane is hydraulically-powered. Clean hydraulic oil is essential for a workflow without interruptions especially in the steering hydraulics, the hydraulic suspension of the axes and the basic crane hydraulic. Cranes with more than 125 tons load weight are separated into the top and the bottom carriage. so the upper part of the crane can be operated completely individually from the rest of the vehicle.

移动式起重机的几乎所有功能都是液压驱动的。清洁的液压油对于不间断地工作是必不可少的,特别是在回转液压系统,液压悬挂桥系统和起重机基本液压系统。起重量超过125吨的起重机被分成了上车系统和下车系统两大部分。所以,起重机的上车液压系统可以完全独立于车辆的其他部分而进行操作。

Solution statement

解决方案

The new KE 2900 fulfills all of these requirements;

Two return connections for both of the pump circuits and two magnet cores working as injury indicators;

By using DIN elements with open end plates, the housing can be converted from NG 1000 to NG 1500 by using a longer filter bowl;

Due to the improved outlet tube, the filter bowl can be stabilized at the box of the filter bowl or at the outlet tube to prevent the suction of air, when spillage occurs.

新的KE 2900可以实现所有这些要求;

针对双循环泵的双回油连接口以及双磁芯损伤指示器设计;

通过使用有开口端盖的DIN标滤芯和更长的滤筒,公称流量可以从NG1000 转换到 NG 1500;

由于改进了出口接管, 当泄漏发生时,接管可以稳固在过滤器滤筒上。当溢出发生时,出口接管也防止吸入了空气。

Customer value

客户利益

Every mobile crane with a size of >125 tons is now able to use one unified filter size;

Depending on the volume flow and the usage of the same filter head you can choose between the NG 1000 and the NG 1500;

Worldwide availability of the required elements;

Simplified diagnostics due to a closed ¼ measurement connection;

Thanks to the modular design, the elements are compatible with mobile cranes of all sizes;

Reduced storage costs due to unified elements.

每台起重量大于125t的移动式起重机,可以统一使用一种型号的过滤器;

在使用同一滤头的情况下,依据流量可以在NG1000和NG1500之间自由选择;

所需滤芯的全球供给;

自锁的G¼” 测量接口使诊断简单;

模块化设计,滤芯可以适用于起重机的所有型号;

由于统一滤芯减少仓储成本。

Challenge

挑战

In the top carriage two large-scale pumps are implemented with a flow volume of 450 l/min. In the worst case more than 900 l/min can reflow trough the differential cylinders into the tank. Both return flow pipes should be equipped with easily accessible magnetic cores. These magnetic cores are an indicator for damages. The return line filter should be based on a modular design and, if necessary, able to handle a flow of 1500 l/min.

Technical Data:

Volume flow: 900 l/min

Filtration rate: 10 μm

在上车中两个大型泵的流量达到了450 l/min。在极端的情况下,超过900 l/min的流量通过差动油缸回流到油箱中。两个回流管都应该配备可访问的磁心。这些磁芯是损伤指示器。回油管式过滤器基于模块化设计,在必要时可处理1500 l/min的流量。

技术参数:

流量:900 l/min

过滤精度: 10 μm
