Pump Selection and Calculation: Three types of pumps are used in the design of industrial hydraulic circuits: a) Piston pumps: they are generally used for high pressures and thus are expensive.
The rod's diameter must be calculated so as to prevent the rod from bumping when the maximum force is applied.
The design of the cylinder has not yet been completed and the rod diameter must be calculated based on the cylinder force applied by the rod. The calculated diameter should be taken into account for the diameter numbers of seamless and stamped pipes available on the market, especially for the construction of the jack. Although hydraulic systems have a pressure of 700 bar and even more, the cost of parts is rising exponentially from 200 to higher, and only when you have to use higher pressures.īy measuring the force and the working pressure of the system, the diameter of the cylinder (jack) can be calculated. It is generally recommended that the pressure should be less than 200 bar. The choice of the pressure that leads to the selection of the pump, the electro-motor and the valves, etc., must be done in such a way that the system will eventually be cost-effective and economical. Hydraulic system pressure selection according to the standard pressure plate in the hydraulic circuits as well as the pressure of the hydraulic pumps in the market and finally the cost of the parts, the working pressure is selected. To design this circuit, we will cover the following stepsįirst, we must estimate or calculate the required force that is supposed to be produced by the jack (according to the use of the jack)
Simple hydraulic circuit Includes an actuator (jack-cylinder) a steering valve and a simple power pack that includes: a pump, an electro-motor, a pressure switch, and so on.
