Parker Motor F12-125-MS-SV-S-000-000-P0

• working principleThe F12-125-MS-SV-S-000-000-P0 motor consists of an internal ring gear and a gear or rotor. The internal gear ring is connected to the housing, and the oil entering through the oil port drives the rotor to rotate around the center point. This rotating rotor is driven by a spline shaft and outputs as a cycloidal hydraulic motor. By changing the input and output flow rates, the motor can quickly reverse direction and generate equivalent torque in both directions.

• structural characteristics

• compact and lightweightThe transmission shaft forms a 40 ° angle with the axis of the cylinder block, which makes the motor structure compact, lightweight, and easy to install and use.

• Piston ring designAdopting a stacked piston ring, it has a small internal leakage and good heat shock resistance, which can ensure the stable operation of the motor under different working conditions.

• bearing configurationEquipped with heavy-duty roller bearings, it allows the drive shaft to withstand significant external axial and radial loads, improving the motor's load-bearing capacity and reliability.

• performance parameters

• displacement：125cc。

• work pressureThe maximum intermittent working pressure can reach up to 480 bar, and the continuous working pressure can reach up to 420 bar, providing high output power.

• speed rangeThe speed range is from 0.5rpm to 7300rpm, which can meet the speed requirements of different application scenarios.

• Hydraulic oil requirementsHLP (DIN51524) hydraulic oil, lubricating oil for A-type automatic transmission and APICD type lubricating oil can be used, as well as refractory material oil and synthetic oil. The ideal viscosity range for oil is 15-30mm ²/s, and during start-up, the viscosity of the oil should not exceed 1000mm ²/s.

• Operating TemperatureWhen the shaft seal material is FPM, the main circuit temperature cannot exceed 80 ℃, and the oil discharge circulation temperature cannot exceed 115 ℃; When the shaft seal material is NBR, it can withstand a leakage temperature of 90 ℃.

• Installation and ConnectionInstall flanges and shaft ends according to current ISO and SAE standards. F12-125-MS-SV-S-000-000-P0 is equipped with SAE standard flanges and shafts, making installation and replacement more flexible and convenient, and can meet the requirements of various mechanical structures.

• application fieldThis motor is suitable for heavy machinery such as pile drivers and rollers, and can also be used in other situations that require high torque and low-speed drive, such as pile head crushers, slag collectors, etc. Its high pressure, high speed, and high reliability enable it to operate stably in harsh working environments, providing reliable support for the normal operation of the equipment.

• Oil management

• Oil selectionMineral based HLP grade hydraulic oil (DIN51524) should be selected, with a viscosity range of 15-30mm ²/s and an acid value increment of ≤ 0.2mg KOH/g.

• filtration systemThe main circuit requires the installation of a 10 μ m filter with a β ₙ ≥ 75. Check the cleanliness of the oil every 500 hours. If it exceeds the standard, replace the filter element or take other purification measures in a timely manner.

• Regular maintenance of nodes

• 2000 hours of maintenanceReplace the fluorine rubber parts of the shaft seal, clean the debris in the piston ring groove to prevent debris from affecting the normal operation of the piston ring and ensure sealing performance.

• 5000 hours of maintenanceCalibrate the pre tightening force of the valve plate, check the bearing clearance. If the bearing clearance is greater than 0.1mm, the bearing needs to be replaced to ensure the accuracy and stability of the motor operation.

• Daily inspection and maintenance

• Check the sealing componentsRegularly inspect the seals of the motor, especially after prolonged high-pressure operation, to check for signs of aging, cracking, oil leakage, etc. If there are any problems, replace the seals in a timely manner to avoid hydraulic oil leakage affecting equipment operation.

• Keep the system cleanWhen replacing or repairing hydraulic oil, ensure that the interior of the hydraulic system is clean to prevent contaminants from entering the system. Normally, external pollution should be prevented, and the fuel tank cap should be well sealed to prevent dust, moisture, and other substances from entering the fuel tank.

• Monitor the operational statusOperators should conduct regular inspections and pay attention to phenomena such as noise, vibration, and temperature changes during motor operation. If abnormal temperature rise, leakage, vibration or noise is found, the vehicle should be stopped immediately for inspection. When conditions permit, vibration monitoring devices, temperature sensors, and other equipment can be installed to monitor the operating status in real time.

• Operation precautions

• Pre startup inspectionCheck whether the motor is installed correctly and firmly, whether the coupling installation meets the requirements, and manually rotate the coupling to confirm that there is no jamming phenomenon. After operation or long-term storage, clean hydraulic oil should be added to the pump and motor housing according to the instructions before starting.

• start operationAdjust the overflow valve in the system to the minimum value and strictly prohibit starting with load. After starting, observe that there are no abnormalities before continuing to operate. After running for a certain period of time, gradually adjust to the required pressure and flow rate. The maximum adjustment value of the safety relief valve shall not exceed the specified value.

• Shutdown operationWhen the pump and motor are stopped, they must be unloaded first and then stopped to avoid damage to the equipment caused by sudden pressure changes.
