Cooling an Overheated Hydraulic System thumbnail image

Cooling an Overheated Hydraulic System

This chart has been prepared for use with an existing hydraulic system which runs at too high a temperature. It may be used to estimate heat exchanger capacity which must be added to reduce the oil temperature to an acceptable level.

Figures in the body of this table show the horsepower needed to drive a positive displacement hydraulic pump, and would be valid either for electric motor or engine drive.

Force Required to Accelerate a Load thumbnail image

Force Required to Accelerate a Load

The purpose of this data sheet is to show how to calculate the extra pressure or torque needed in a hydraulic system to accelerate an inertia load, Item (3), from standstill to its final velocity in a given time, assuming the pressure needed for Items (1) and (2), the work load and the friction resistance has already been calculated or assumed.

Two-Hand Safety Control of Air and Hydraulic Circuits thumbnail image

Two-Hand Safety Control of Air and Hydraulic Circuits

Where cylinders are operating mechanisms which might present a safety hazard to the operator, dual controls may be provided. These require the use of both hands to start the cylinder and to keep it in motion. Dual controls are also used on large presses which require two operators. Each operator has a control; neither can start the press until the other is ready.

Selection Guide for Electric Wire Size thumbnail image

Selection Guide for Electric Wire Size

When choosing the conductor size for electrical wiring, there are TWO important factors which must be considered, and these are: (1), the safe current-carrying capacity without overheating, and (2), keeping the voltage loss to an acceptable minimum.

Cylinder Force for Punching, Notching and Shearing thumbnail image

Cylinder Force for Punching, Notching and Shearing

An approximation can be made of the cylinder force needed to punch a hole, slot, or notch, using this method: Find the cross section, in square inches, of the section to be sheared.

Automatic Reversing Circuits for Presses thumbnail image

Automatic Reversing Circuits for Presses

Circuits on this data sheet are intended for air and hydraulic presses, to automatically retract the press cylinder when a pre-set tonnage has been reached, this retraction to override the operator and take place even though the operator may still be holding down a foot valve or foot switch.

Factors which Influence the Speed of an Air Cylinder thumbnail image

Factors which Influence the Speed of an Air Cylinder

It is very difficult to calculate and predict the speed of an air cylinder; there are too many variables which influence speed and on which it is difficult to gather accurate data. We must rely mainly on good design practices and use the benefit of past experience. It is better to have the cylinder speed too fast to begin with because it can always be reduced with a speed control valve, but if it is too slow to begin with, it is more difficult to increase its speed later.
