Hydraulic components need protection

Hydraulic systems & components

1st Quarter 2014 Hydraulic systems & components

Good filtration needs to be an integral part of an hydraulic circuit to ensure long life and proper operation of the pumps, valves and motors. Hydraulic circuits are designed in all shapes and sizes, both simple and complex, and they all need protection from damaging contamination. If unfiltered, abrasive particles entering the system can damage sensitive components.

This illustration of a simple hydraulic valve shows how particles damage components. If a particle lodges between the spool and valve body, it will erode small flakes from the metal surfaces. As these flakes are moved back and forth by the action of the spool, they can roll into a burr that jams the spool and disables the valve.

Studies show that typically 70% of hydraulic component replacement is necessary because of surface degradation and most of this is due to mechanical wear. It is the job of the hydraulic filter to remove these particles from the oil flow to help prevent premature component wear and system failure; and as the sophistication of the hydraulic system increases, the need for reliable filtration protection becomes even more critical.

Proper filtration of hydraulic fluids can lengthen component life. Don’t cut costs by eliminating hydraulic filters. It could cost you more in the long run in major component repair.

How to protect against water hammer
SA Gauge Editor's Choice Hydraulic systems & components
Water hammer is a high-pressure surge or wave created by the kinetic energy of moving fluid when it is rapidly forced to stop or change direction, altering the liquid’s velocity. The progression of the water hammer shockwave needs to be detained and slowed before reaching the instrument sensor. SA Gauge manufactures several such devices in order to achieve this.
