产品概述

LDF系列马达是我公司最新推出的新型结构马达。它吸收了 国内外曲轴杆式液压马达的优点，大大的提高了液压马达的 压力等级。该系列马达具有可靠性好、效率高、寿命长、噪 音低转速范围宽等一系列特点，可应用于船舶、矿山、建筑 冶金、石油、煤矿、地质钻探、塑料行业等各种机械的液压传动系统中。

主要特点

1：LDF系列液压马达在连杆和曲轴运动副间设计成静压平衡 结构、使摩擦副得到良好的润滑，改善了轴的受力。

2：由于摩擦功损失和发热减小，马达的机械效率和启动效率得到提高，从而也提高了马达的工作压力。

3：该系列马达的曲轴采用了分体结构，提高了曲轴的使用寿命。

4：该系列马达的关键部位采用特殊材料和热处理工艺，有效的提高了马达的使用寿命。

5：该系列马达的外形尺寸和性能参数与（KAWASAKI- STAFFA HMB系歹U马达）一致，可直接替代进口。

注意事项

除参照LD系列马达以外，还需注意以下一点：

因该系列马达采用了静压平衡结构，使马达增加了泄漏，特 别要注意在外接泄油管时,泄油管的内径不能小于12mm, 否则将冲坏油封。接泄油管接头时，螺纹拧入的长度不能太 长，以免损坏零件。

Product overview

The latest presented product-LDF series hydraulic motor, not only reflects our rich experience in hydraulic motor manufacture, but absorbs the advantages of cranLDhaft connecting rod hydraulic motor from both home and abroad.

Its main features

1：Static pressure balance structure between shaft joint and connecting rod, thereby, it well smoothes the fiction joint and releases shaft pressure.

2：Because of the decrease of the fiction work and heat loss, mechanical and starting efficiency increase, the work pressure of motor also improves.

3：The shaft of this series employs fission structure to prolong motor life.

4：All the key parts of this series use special material and employ special heat treatment, therefore, efficiently prolong motor life.

5：As the dimension and performance data of this series are the same as HMB series of KAWASAKI-STAFFA Company, it could replace HMB directly.

Notes

Besides those mentioned in the LD series, please also note that:

Because this series employs static pressure balance structure, the motor leakage increase accordingly. When connect drain port from outside, the inner diameter should not less than 12mm, otherwise will damage the shaft seal. Also, when connect the tie-in of the drain port, do not screw in too much.
