Eaton Hydraulic Pump
Eaton Hydraulic Pump
● Structural characteristics/advantages of heavy hydraulic pumps and motors:
● Pressure up to 6000 psi (420 bar)
● Speeds up to 4510 rpm
● Bearing design life up to 10,000 hours
√ Drive shaft-there are many forms to choose from as needed. There is a high-strength swash plate in the variable pump and variable motor, which can prevent deformation under large load.
√ High-strength cast iron shell-can buffer noise and withstand high shell pressure.
√ There is a large flow check valve in the pump-to minimize the system pressure drop.
√ There is a charge pump-cycloid fixed rotor pump in the main pump. There are several displacements to choose from to meet various requirements, all of which are made of cast iron.
√ Plug-in shaft seal-making it easy to maintain, the mechanical end seal design can withstand high speed and high shell pressure.
√ Advanced cylinder design-can withstand high pressure and high speed
√ Sliding shoes with fixed clearance-Models 33 to 64 can run at high speeds and reduce friction. Model 76 is a spherical guide.
√ Plugging—The mating surface with the cylinder hole is longer, so there is less leakage.
√ Hydraulic servo control-can reduce the control pressure, the operation force is small, the large diameter servo cylinder piston can keep the position of the swash plate unchanged and play a buffering role.
√ Large oil drain-reduce the back pressure of the housing as much as possible.
√ Bi-metal support disk-steel back can withstand high speed and back pressure, copper surface can improve support performance.
√ Disc valve-quenched steel can last a long life.
√ Rear disc-large channel to reduce loss. For the fixed motors of type 33 to 64, there are rear interface or opposite interface for selection.
√ There is a mounting branch at the rear-it can be used to connect the dual pump or install a through shaft.
√ Relief valve-There are pilot-operated plug-in relief valve and fast-acting direct-acting relief valve for selection.
√ Control system-there are many control methods according to application needs
To choose from.
√ Interface-SAE (American Society of Automotive Engineers) standard 61 and 62 and O-ring interface are available.
