The working principle of the hydraulic pump is the same for all the other pumps. Due to mechanical action, the pump creates a partial vacuum at the inlet. As a result, the fluid is forced into the pump’s input by air pressure. The fluid is subsequently pushed into the hydraulic system by the pump. Two check valves are included in the pump. Check valve 1 is linked to the pump’s inlet and permits just that fluid to enter the pump. Check valve 2 is attached to the pump discharge and is the sole way for fluid to depart.

A partial vacuum is formed in pump cavity 3 when the piston is moved to the left. Check valve 2 is held against its seat by the vacuum, allowing the fluid inside the cylinder to flow through check valve 1 under atmospheric pressure. The fluid movement closes check valve 1 and opens outlet valve 2 when the piston is pushed to the right. The volume of fluid displaced by the piston is ejected from the cylinder forcibly. The displacement volume of the pump is the volume of fluid displaced by the piston during the discharge stroke.
Although the actual speed and torque necessary may sometimes be varied while keeping the required horsepower, the application of the hydraulic motor generally defines the required horsepower and motor speed range. The type of motor chosen is determined by the level of reliability, longevity, and performance required.
Once the type of fluid has been decided, the actual size is chosen depending on the estimated life and the overall cost of the machine installation. A fluid motor running at less than rated capacity will have a service life extension that is more than proportionate to the lower operating capacity.
When a motor is operating at maximum system pressure and maximum shaft speed, it produces its maximum horsepower. The Riverlake hydraulic motor’s original cost will be the lowest if it is always used under these conditions. However, in cases where the output speed must be reduced, the entire cost of the motor with the reduced speed must be considered in order to reduce overall drive installation costs.
Malfunctions of Hydraulic Motors
The majority of motor issues are caused by the use of the wrong fluid, inadequate maintenance, or improper operation. The motor is identical to the rest of the hydraulic system’s components. It must, first and foremost, have clean fluid insufficient supply, of the correct grade and viscosity. Poor maintenance is a close second in terms of producing serious issues.
- Failure to inspect and repair pipes and connections to prevent leaks: defective connections can allow dirt and air into the system, lowering pressure and causing irregular performance.
- Improper motor installation: Misalignment of the motor shaft can lead to bearing wear and efficiency loss. A misaligned shaft can potentially cause shaft failure by reducing torque, increasing friction drag and heating, and causing shaft failure.
- Failure to identify the source of a motor failure: When a motor fails, always check for the source of the problem. Failure will recur if the root cause is not addressed.
Finally, exceeding a motor’s operational limits increases the likelihood of failure. Pressure, speed, torque, displacement, load, and temperature are all design constraints for every motor. Because of motor slippage, excessive pressure can build heat and cause the motor to exceed torque limitations.
Excessive speed can cause bearings and other internal components to heat up and wear out. Excessive torque can cause bearings and the motor shaft to become fatigued and stressed, especially in applications that require frequent motor reversing. Bearing and shaft fatigue can be caused by excessive load. Excessive heat can also reduce efficiency by making the oil thinner and causing quick wear due to a lack of lubrication.
