On the static pressure fan system brick machine

We all know that when brick machine hydraulic system temperature is too high , will inevitably lead to the device is not working properly , so we must have a cooling operation, then Rising Heavy brick making machine hydraulic system is how to cool , heat What is the principle ?
     
Is now widely used in static pressure fan system , dosing pumps driven by a hydrostatic fan and overall priority valve. Priority valve and the temperature and pressure valve from the engine heat to disperse a large number of parameters to control the air flow . After the excess hydraulic oil can be applied to other priority valve hydraulic drive device . The advantages of such systems can be independently cooling fan assembly , and can shorten the length of the external gear , with a high price , the fan speed is controlled by an external gear pump flow decisions.
In short, the hydrostatic drive hydraulic driven fan control or optional electro-hydraulic control . Machine hydraulic control is generally used in a simple one or two input ports in the system, but there is little more complicated input port systems are generally used by a piston pump or external gear pump driven electro-hydraulic control system. As long as reasonably necessary to choose, can achieve the desired cooling effect.
