Hydraulic Cylinder Repair Guide and Tips

Posted on by

In this modern world, with all the latest technologies in machinery, the use of Hydraulic cylinders plays a major role in a wide range of applications. This system is a simple arrangement of pistons and cylinders which is capable of lifting heavy objects. Most car parts or heavy machinery function on the principle of hydraulics. There are a few other mechanisms like bulldozers, elevators, excavators, and forklifts that use hydraulic cylinders too.

These systems are available in varying sizes, for instance when installed in automobiles, they are available in small sizes, whereas, in heavier applications like dumpster trucks or heavy bulldozers they are available in larger sizes for smoother maneuvering and easy lifting. Nevertheless, all hydraulic cylinders share the common components, repair, and maintenance procedures.

Before we move ahead with the hydraulic cylinder repair procedures, let us find out the general causes that lead to cylinder malfunctioning.

  • Causes of Failure of Hydraulic Cylinder System
  • A bent piston rod can encumber the hydraulic system.
  • Due to consistent long use, there can be a crack in the system.
  • Also, due to persistent wear and tear, the seal of the hydraulic cylinder might crack or break.
  • There are chances of the piston rings getting damaged.

Whenever you indulge in some cylinder repair work, keep your repair tool kit ready for use. Normally, a tool kit consists of lubrication, new shaft seals with O-shaped rings, and a new cylinder rod.

 

Basic Introduction To Hydraulic Motors

Posted on by

The hydraulic motor converts fluid pressure into rotary motion. The pressurized fluid from the hydraulic pump rotates the motor output shaft by pushing the gears, pistons, or propellers of the hydraulic motor. 

Hydraulic motors can be used for direct-drive applications where adequate torque capacity is available or via reduction gears. You can also get more information about hydraulic motors through the web.

Most hydraulic motors are required to operate under reversible rev and stop conditions. Hydraulic motors often have to operate at relatively low speeds and high pressures and can be exposed to large temperature and speed fluctuations during normal operation. Hydraulic motors can provide very high torque.

There are three types of hydraulic motors: gears, pistons, and blades. The toothed motor is compact and offers continuous operation at nominal power with moderate efficiency. 

They have a high tolerance for hydraulic oil contamination, which is important for applications in dirty environments. An external gear motor consists of a pair of combined gears housed in a single housing. 

Both gears have the same tooth shape and are driven by fluid under pressure. One gear is connected to the output shaft and the other to the idling. Pressurized fluid enters the housing at the junction of the gears. 

This forces the gears to rotate and follow the path of least resistance around the perimeter of the housing. The fluid exits at low pressure on the opposite side of the motor.
