Symptom: Pump Noisy

 1. Cause: Cavitation

     Corrections DESIGN: Enter a larger hose.

    Review procedures in the field: to use a filter larger intake, use of oil with lower viscosity.

     2. Cause: Restricted Admission.

         DESIGN corrections in revenue should be at least 50% larger than the exhaust. Place the pump does not exceed 24 inches above the oil level.

          Reviews in the area: Clean the air filter box.

          3. Cause: Loss of suction.

             Corrections DESIGN: Keep the lines of simple aspiration.

            Reviews in the area: pour oil on the joints when the pump is running and the common place where the pump is running low.

           4. Cause: Loss of air intake shaft packing.

               Corrections DESIGN: Use flexible drive coupling with Stiff tank top for rigidity. 

                 Reviews in the area: Lubricate or extension of the packaging. Precise alignment shaft pump.              

        5. Cause: air sucked into the system of dams.

               Corrections DESIGN: Insert the intake and exhaust pipes on both sides of the plate baffle. Minimum oil circuit to the pump.

              Reviews in the area: Raising the level of oil in the tank. Relief under the oil level. The oil has an anti-foam additive?

Machines using the principles of hydraulics are bulldozers, excavators, forklifts, cranes and excavators. Hydraulics is also the reason why cars in service centers, then lifted, the technicians can work under them.

It is also launched for the same technology, elevators. Flat surfaces are managed and controlled by hydraulics, and the use of hydraulic brakes in your car.

The idea behind the hydraulic system is simple. It says the force is applied at one point to another point with the use of an incompressible fluid, which is usually a kind of oil transferred. In this process, multiplied by the force.

In a simple hydraulic system, two pistons through a pipe which is filled with oil are linked. These pistons are two glass cylinders filled with oil should be installed. The glass bottles are then connected through a tube filled with oil connected.

If force is applied to a piston, the force is transmitted to the plunger after using the oil in the pipe. Because the oil can not be compressed, its effectiveness will be applied very well, because all power points in the second piston.

Come line the cylinders can be of any length, shape and size connected, it can bend, twist, or rotate through all the things that separate the two pistons. This behavior can also fork, which simply means that a master cylinder with one or more slave cylinders can go.

In hydraulics, it is very important that the system eliminates air bubbles. The presence of air bubbles in the system affects its efficiency, the force will be applied in a piston compresses the air in the bladder, such as transfer to the second piston.

The brakes of a car are the simplest example of the piston-driven hydraulic system. As the brake pedal is pressed, it pushes the piston in the brake? S master cylinder. This action provides four slave pistons on the brake pads against the brake rotor that drives your car.

The strength of your leg is not enough to stop the car, the car is a multiple of the force. This is called the hydraulic multiplication. In most cars there are now two main cylinder engine with two cylinders of each dish.

This design allows the car to slow down or stop, even if there are problems in the first stop, or when an oil leak. Occur in other hydraulic systems, valves, cylinders and pistons connected to a fuel pump high pressure oil. The valve is in front and behind to force the pistons.

You see large hydraulic machinery on building sites. These machines are powered by Hydro Excavators, skidloaders (also known as known? Bobcat?, Because that was the name of its first owner) and the dump truck.

When you see these machines to note that despite the huge size, the common driving force comes from the hydraulic system.
