Hydraullc control panels are deslgned to operate monltors from a distance by using hydraullc prlnciples. Controlling unlts as a minimum consistlng of an atmospherlc pressure hydraullc oil-containing tank, an electric motor to pressurize the oil, and bidirectional dlstributlon valves. The electric motor pressurizes the oli and sends it to a manifold where bldlrectlonal valves dlvert the flow to move monitors in one directlon or to another. For security reasons, C.S.I. S.r.l. uses manual hand operated pumps attached to the system to give the possibility to the user to operate monitors in case of power failure. Optlons for hydraullc control units are multiple as described below.
Simple hydraulic controlling systems consisting of an oil tank, a single electric monitor, manually hand operated bidirectional valves and a manual hand pump. With this kind of equipment, the operator should start the hydraulic motor by using an electric button and operate the monitors manually by levers of bidirectional valves.
In addltion to the above, it ls posslble to attach an addltional backup hydraulic motor, to be used in case of fallure of the main hydraulic pump.
Control of the monltor's by using manual hand operated valves.
Another option to operate the monitor is using a single hydraulic reversible motor for each movement needed. For example if a monitor has three movements, which are vertical horizontal and nozzle movements, there are three motors without directional valves. The system functions by rotating the motors in one or another direction by inverting them electrically. These systems have redundancy problems, since if an electric motor fails, that movement will be lost. These are systems not recommended by C.S.I., but on request can produced with simple turrets to install below the monitor.
Hydroelectric controlling systems are also available from our product range, where simple hydraulic units are equipped with remote operated bidirectional valves. These systems require a control panel as described in the previous section to operate valves, run the hydraulic pump, or put in service the reserve pump.
Hydraulic control panels generally havine a limitation of distance between monitors and control panels, which is approximately 300 meters. These limitations come from the pressure loses during fluid travel which can be compensated up to certain limits by using different sizes of hydraulic piping.
There is no possibility to attach intermediate control panels to the main hydraulic control panels, which act on the hydraulic principle, but additionallocal electric control panels could be attached to the system to control the hydraulic monitors from multiple access points electrically rather than hydraulically.
