YPR SERIES REFRACTORY HYDRAULIC PRESS

YPR series refractory hydraulic press isdeveloped by FOSHAN HENGLITAI MACHINERY CO., LTD. for producing refractoryproducts in a dry-pressed way. The integration of mechanical, electrical,hydraulic, pneumatic and computerization into a machine, the refractoryhydraulic press consists of main body, hydraulic system, feeding system,electric control system, mould loading/unloading system and so on.The filling,pressing, demould, unloading and oil spraying are fulfilled automaticallythroughout the cycle. Apart from the inherited features of HLT products,stability, advanced performance and low failure rate, the refractory press alsoenjoys the below advantages through rationalization of core technology:


--Wide applicability

Thanks to the optimum hardwareconfiguration, various settings are made possible to meet the needs for productof raw material characteristics, shapes and sizes.


--Accurate product size control

The displacement of pressing cylinder andmobile mould frame is monitored by high-performance linear position sensor. Theproduct size is controlled in a close-loop way that the adjustment is performedautomatically to ensure the tolerance.


--Dual pressing 

The floating mould frame and main cylinderare controlled accurately in such a way that movement is synchronized,realizing the dual pressing for optimum density distribution.


--Precise close-loop pressure control

With the help of the feedback frompressure transducer and data processed by PLC, the pressure is controlled in aclose-loop manner for varied speed pressurization and multiple deaeration tominimize porosity and increase density.


--Volumetric filling device

Volumetric filling device equipped withmaterial crusher and mixer, controlled by proportional technology, makes surethat the material in distributed evenly in the mould cavity and effectivelyavoids clustering and liquation in order the control weight variation withinthe limit.


--Fast mould change-over

Fast mould change device is controlled byhydraulics to make it possible to change the mould and lock it automatically tomeet the demand of producing refractory product with frequent mouldchange-over.


--Highly automated

Filling, forming, extracting and gripping,etc, in the manners of mechanic, electric, hydraulic and pneumatic, are allcontrolled by automation to reduce human error and labor cost.


--Digitalized smart control system

User-friendly interface and remotediagnosis technology. The switch of working mode, pressure control, thicknessadjustment, plunger/speed control, etc are performed on the HMI. The errormessage and PLC input/output dynamic simulation are also shown on the HMI. Witha DVP module, the DVP card value can be accessed and modify easily. The remotecommunication device can set up a remote control system for trouble-shootingand upgrade of program conveniently.


--Safe and energy-saving

An overall safety system to prevent the damageto staff and machine caused by human error which is seen in friction press. Thenoise level is controlled effectively during the pressing stage and transportsystem for material is properly sealed to avoid dusting, so as to improveworking environment for workers and reduce harm to health. Variabledisplacement pump with constant power control are used as main pump andauxiliary pump, respectively, to reduces heat dissipation and save energy.



--Low maintenance cost

Full-flow filtering and heat exchangingsystem greatly reduce the system malfunction caused by contamination of oil.Oil temperature is maintained at an optimum level. The hydraulic units andelectronics are from world-famous suppliers.
