MS hydraulic motor

Features
1. The whole structure of MS hydraulic motor adopts chip stacking according to its modular design which consists of mechanical output module, hydraulic function module, hydraulic valve module of and mechanical brake module. The modules can conveniently match with various main engines.

2. Thanks to its plane valve technology, our product has low pressure and temperature sensitivity, and it can automatically compensate for the abrasion, thus ensuring long-term high volumetric efficiency of product. Meanwhile, the product can improve mechanical efficiency due to the adoption of roller, the plunger structure, simple structure of force transmission and little friction.

3. By optimizing the design of the stator curve, MS hydraulic motor can reduce the stator contact stress and ensure the output torque and speed to be unchanged at the same time. Furthermore, the product has large working pressure which can be 40 MPa due to the new stator manufactured by new materials and new technology. The product has small force transmission mechanism inertia, and its roller block uses antifriction material. Therefore, our product has high starting efficiency and excellent performance in low speed which the lowest stable speed is less than 0.5 rpm.

4. Our hydraulic motor can bear large axial force and radial force due to the adoption of independent set of mechanical output module and large diameter output shaft and bearing. It can be directly connected with gear output or mounted on the driving wheel of vehicle.

5. Thanks to the adoption of modular vane mechanism and superimposed mechanical transmission device, output shaft can directly realize safety brake and parking brake.

6. Our hydraulic motor is divided into single displacement type and double displacement type. Single displacement type is full displacement output while double displacement type can be controlled by the control valve to achieve full displacement and half displacement output, thus achieving speed control. Our product has various specifications covering all fields of application, and its displacement range is 0.2 L/r to 15L/r.

7. Our product has small overall dimensions and flexible arrangement of machine design.

Notes
1. Different models of motor have different radial bearing capacity.
2. The same type of product has different radial bearing capacity when it has different stress positions.
3. In practical use, the product should bear radial load in the optimum region, thereby obtaining long service life of design.

Degree of Pollution and Viscosity of Oil
Oil pollution is one of the main causes of hydraulic motor failure. Both internal residues or external contaminants will seriously affect its reliability and lifespan. Our Our product demands the degree of pollution of oil to be lower than the 18/13 grade in the ISO4406. Generally, the product system should set up a fine filter with over 10 μ m nominal filtration accuracy and about 25 μ m absolute filtration accuracy.

The range of product's oil viscosity is 9cst to 2000 cst and the optimum oil range is 20 to 50 cst. The oil temperature range is -20℃ to 70℃. Generally, our product on the fixed equipment should use HV46 or HV68 anti-wear hydraulic oil while the product on the walking machine should use the low temperature hydraulic oil with the same grade but with better viscosity characteristics.

Mechanical efficiency and volumetric efficiency of our product are marked on the product sample. During the actual use, we should notice its starting efficiency with load is usually 70% to 80% mechanical efficiency of rated operating condition. Therefore, customers should know the selection principles of our product which are as follows:

1. Long-time working pressure of MS hydraulic motor should be less than the rated pressure.
2. The actual output power of product is less than the maximum power of sample.
3. In order to make the product work reliably for a long term, the best condition should be in high efficient area and we should notice the starting efficiency is lower than the efficiency in rated condition.
4. In terms of product displacement, we should try to use 0 groups of displacement
in the base type.

Installation Requirements
1. MS hydraulic motor has a variety of installation modes. Its bracket must have enough rigidity and the product should be installed to ensure its drive shaft and output shaft to be concentric during the installation.
2. In terms of leak, the oil drain hole should be individually connected back to the fuel tank. Generally, product shell can allow maximum pressure of 0.05MPa. Customers can consult our company for special order if the user has its special condition requirements.
3. Our product which will start for the first time must be filled with clean hydraulic oil in order to prevent our productfrom damage. Meanwhile, the highest level position of drain tube should be higher than the highest level position of shell in case of empty oil of the product.
