產(chǎn)品概述

LDF系列馬達是我公司最新推出的新型結(jié)構(gòu)馬達。它吸收了 國內(nèi)外曲軸桿式液壓馬達的優(yōu)點，大大的提高了液壓馬達的 壓力等級。該系列馬達具有可靠性好、效率高、壽命長、噪 音低轉(zhuǎn)速范圍寬等一系列特點，可應(yīng)用于船舶、礦山、建筑 冶金、石油、煤礦、地質(zhì)鉆探、塑料行業(yè)等各種機械的液壓傳動系統(tǒng)中。

主要特點

1：LDF系列液壓馬達在連桿和曲軸運動副間設(shè)計成靜壓平衡 結(jié)構(gòu)、使摩擦副得到良好的潤滑，改善了軸的受力。

2：由于摩擦功損失和發(fā)熱減小，馬達的機械效率和啟動效率得到提高，從而也提高了馬達的工作壓力。

3：該系列馬達的曲軸采用了分體結(jié)構(gòu)，提高了曲軸的使用壽命。

4：該系列馬達的關(guān)鍵部位采用特殊材料和熱處理工藝，有效的提高了馬達的使用壽命。

5：該系列馬達的外形尺寸和性能參數(shù)與（KAWASAKI- STAFFA HMB系歹U馬達）一致，可直接替代進口。

注意事項

除參照LD系列馬達以外，還需注意以下一點：

因該系列馬達采用了靜壓平衡結(jié)構(gòu)，使馬達增加了泄漏，特 別要注意在外接泄油管時,泄油管的內(nèi)徑不能小于12mm, 否則將沖壞油封。接泄油管接頭時，螺紋擰入的長度不能太 長，以免損壞零件。

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.
