GFB hydraulic transmission device instruction manual

I. Overview:

The GFB series transmission device is composed of various hydraulic valve blocks, hydraulic motors, planetary reducers and other components. It also has the characteristics of high efficiency when starting and working, less energy consumption, low noise, compact size, beautiful appearance, and good economy. It can be widely used in railway and truck cranes, ships, oil fields, coal mines, ports and other equipment. 

2. Matters needing attention:

1. Please read this manual carefully before ordering, and let us know the actual working conditions. Our factory can assist in model selection and establish customer files for after-sales service.  

2. The hydraulic rotary device can rotate in both directions, and the user can realize it only by exchanging the oil inlet and outlet of the hydraulic motor. 

3. All products are allowed to be installed in any direction, but it should be noted that the leakage port of the hydraulic motor should be located above the horizontal plane of the shaft center. If the customer requires that the shaft output direction is upward or higher than the horizontal direction, please specify when ordering, and our factory will provide the leakage port A check valve is added to prevent the lack of lubricating oil in the housing. 

4. The shell pressure of all products does not exceed 0.3MPa. If you have special requirements, please contact our factory. 

5. Working fluid: The working oil of the hydraulic motor is wear-resistant hydraulic oil. The ideal working oil temperature is 30°C~50°C and the allowable oil temperature is -20°C~80°C. In special cases, low-condensation hydraulic oil should be used. The ideal hydraulic oil viscosity is 40~60 centistokes. 

6. Filtration precision of oil used in hydraulic motors: 25 micron or better filtration precision is recommended. 

7. Please add two-thirds of the volume of gear oil to the gearbox before use, and fill the hydraulic motor with hydraulic oil.

8. After 200 hours of use for the first time, please replace the gear oil and hydraulic oil. The brand of the oil is the same as the original one. Replace every six months thereafter.

叶片液压电机：由于工作压力油的作用，承载力不平衡导致电机转子扭矩。叶片式液压电机的导出转矩与液压电机的排气量和液压电机进出油孔之间的压差有关，其转速比由输入液压电机的总流量决定。由于液压电机一般需要能正反转，叶片式液压电机的叶片应切向放置。为了更好地使叶片根处自始至终通有工作压力油，在回、压油腔通人叶片根处的通道应该设定节流阀，为了更好地保证叶片式液压马达在工作压力油通人后能正常的运行，务必使叶片顶端和电机定子内表层密切触碰，以确保较好的密封性，因而在叶片根处应设定扭矩扭簧。叶片式液压马达体积小，惯性扭矩小，姿势灵巧，液压马达减速机一体适用于换相频率高的场所；但是泄漏量比较大，低速档工作时不稳定。因此，叶片式液压电机一般用于转速比高、转矩小、操作规程灵巧的场所。
