YPRSERIES 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:


--Wideapplicability

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


--Accurateproduct 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.


--Dualpressing

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.


--Preciseclose-loop pressure control

With the help of the feedback from pressuretransducer 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.


--Volumetricfilling 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.


--Fastmould 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.


--Highlyautomated

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.


--Digitalizedsmart control system

User-friendly interface and remote diagnosistechnology. The switch of working mode, pressure control, thickness adjustment,plunger/speed control, etc are performed on the HMI. The error message and PLCinput/output dynamic simulation are also shown on the HMI. With a DVP module,the DVP card value can be accessed and modify easily. The remote communicationdevice can set up a remote control system for trouble-shooting and upgrade ofprogram conveniently.


--Safeand energy-saving

An overall safety system to prevent thedamage to staff and machine caused by human error which is seen in frictionpress. The noise level is controlled effectively during the pressing stage andtransport system for material is properly sealed to avoid dusting, so as toimprove working 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.


--Lowmaintenance 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.
