YPR SERIES REFRACTORY HYDRAULIC PRESS
YPR series refractory hydraulic press is developed by FOSHAN HENGLITAI MACHINERY CO., LTD. for producing refractory products in a dry-pressed way. The integration of mechanical, electrical, hydraulic, pneumatic and computerization into a machine, the refractory hydraulic 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 automatically throughout the cycle. Apart from the inherited features of HLT products, stability, advanced performance and low failure rate, the refractory press also enjoys the below advantages through rationalization of core technology:
Wide applicability
Thanks to the optimum hardware configuration, various settings are made possible to meet the needs for product of raw material characteristics, shapes and sizes.
Accurate product size control
The displacement of pressing cylinder and mobile mould frame is monitored by high-performance linear position sensor. The product size is controlled in a close-loop way that the adjustment is performed automatically to ensure the tolerance.
Dual pressing
The floating mould frame and main cylinder are 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 from pressure transducer and data processed by PLC, the pressure is controlled in a close-loop manner for varied speed pressurization and multiple deaeration to minimize porosity and increase density.
Volumetric filling device
Volumetric filling device equipped with material crusher and mixer, controlled by proportional technology, makes sure that the material in distributed evenly in the mould cavity and effectively avoids clustering and liquation in order the control weight variation within the limit.
Fast mould change-over
Fast mould change device is controlled by hydraulics to make it possible to change the mould and lock it automatically to meet the demand of producing refractory product with frequent mould change-over.
Highly automated
Filling, forming, extracting and gripping, etc, in the manners of mechanic, electric, hydraulic and pneumatic, are all controlled by automation to reduce human error and labor cost.
Digitalized smart control system
User-friendly interface and remote diagnosis technology. The switch of working mode, pressure control, thickness adjustment, plunger/speed control, etc are performed on the HMI. The error message and PLC input/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 communication device can set up a remote control system for trouble-shooting and upgrade of program conveniently.
Safe and energy-saving
An overall safety system to prevent the damage to staff and machine caused by human error which is seen in friction press. The noise level is controlled effectively during the pressing stage and transport system for material is properly sealed to avoid dusting, so as to improve working environment for workers and reduce harm to health. Variable displacement pump with constant power control are used as main pump and auxiliary pump, respectively, to reduces heat dissipation and save energy.
Low maintenance cost
Full-flow filtering and heat exchanging system greatly reduce the system malfunction caused by contamination of oil. Oil temperature is maintained at an optimum level. The hydraulic units and electronics are from world-famous suppliers.
