YPT automatic hydraulic press waterpermeable brick series (“YPT series”) is an advanced press developed by HLTcompany with the latest technology. Based on HLT over 50 years machineryoperation experience and 30 years production and research techniqueaccumulation. In resulting to YPT series possesses all advantages from classicHLT press which are advanced, reliable and energy-efficient.

Structure:

Mainframe adopts mature “Three-Beams,Four-Columns” structure, offering an excellent mechanics performance while inpressing cycles. Besides, the classic upper large-volume oil tank and lowerpre-filled valve structure has brought a great improvement at fillingefficiency. In relation to the thick bricks, long-traveling oil tank, YPTseries configures with strong ballast resistance guiding belt and “Four-column”guiding structure, which minimizes the strain that are typical of the rapidcycles the machine is able to carry out and offering a better control inproduct precision.

Performance:

pressure valve groups utilize differentindependent control oil circuit structures within various pressing phases.Minimizes the interference among different pressing actions, so that ensuring abetter controlling performance and stability in the pressing process.Moreover,  the hydraulic components arecommonly used in YPT series which is conducive to the maintenance of the press.

--Servo ejecting device is able to providemultiple feeding. The closed-loop controlling technique can target the bricksaccurately and ensure an accurate control on the filling thickness of differentlayers.

--Configures with “l(fā)ack of powderprotection scheme” , “Anti Weight protection scheme”  and “ Double plunger displacement sensorsdetecting  and  protection scheme”.

--Configures with oil-level alert switch,avoid the damage due to oil starvation.

--Adopt with variable pump with constantpower control, increasing in pressing speed, reducing in heat production andleading a outstanding energy economy.

--An external multiplier offersacceleration function, speeding up the stroking frequency of the moving partsby making full use of the energy produced by multiplier’s reverse drive.

Advantages:

--Accord with pressing techniques, bettercontrol of upper and lower mould and main cylinder in the pressingprocess.

--Anti load capacity design in mainframeoffering the thick bricks a better quality of forming and safety of themachinery.

--Using closed-loop control servo ejector,it has accurate positioning and it can precisely control on the fillingthickness of different layers as well as strictly control the thickness ofbrick.

--It provides floating mould frameinterface so as to achieve floating mould pressing and improve the quality ofbrick molding;

--Multiple protection scheme (“Lack ofPowder Protection Scheme”, “Anti Weight Protection Scheme”, “Plunger withDouble Displacement Sensors”, “Low Oil-Level Alert”, etc. )

--Outstanding oil filling circuit design,variable pump, external multiplier with acceleration function, speeds up inpressing speed.
