Hydraulic Press System:

The hydraulic press system device is arranged on the right side of the press, with cartridge integrated system, flexible action, reliable work, good sealing performance. The hydraulic pump comprises an oil tank, a high-pressure pump, motor, cartridge valves and other components.

We try our best to prolong the service life of the hydraulic press,there are some measures to eliminate oil spills and to prevent valve seizure:

Oil Pump

（updated from YCY to SY）

The flange connection has a good sealing effect and prevents oil leakage.

Cartridge Valve

The cartridge valve is inteqrated into the system to reduce leakagepoints, reliable operation and long service life.

Combination Gasket

All oil joints are sealed with a combination of gaskets, internally with rubber, externally with customized red copper.

The advantages:

(1).The ductility of red copper is strong, making the bond tight;

(2).The red copper can effectively protect the rubber skin from breakage.

Sealed Ring

After rough machining on an ordinary lathe and finishing by a CNC lathe, the R angle is processed more smoothly, the quality is completely uniform, and the seal is tight and difficult to leak.

Piston Rod And Column

(1).Medium-frequency hardening of 45 steel, deepening the material 2-3 mm, making the surface hardness of the piston rod to 55 ,effective solution to seal ring injury，not easy to scratch it.

(2).For the workpiece after medium-frequency quenching, we use the lathe to soft throw it, and then use an cylindricall grinding machine to repair the deformation, to ensure the accuracy.

Hydraulic Press Tank

Shot blasting combines three new processes of high-pressure vacuuming dough clearance.After the equipment is commissioned, the fuel tank is opened again, and the hydraulic oil flows into the main tank through the high pressure, and the components of each part are cleaned twice.

1. What is the nominal pressing force of the Dingrun YQ41-20T Single Column Hydraulic Press?

According to the product technical specifications the press delivers a nominal force of 300 kN (approx. 30 tonnes). Note: the model name includes "20T", but the published spec shows 300 kN. Please confirm final rated capacity with the supplier before purchase.

2. What motor power and electrical options are available?

The product summary lists a 4 kW motor and the technical table shows configurations with 2.24 kW. Voltage options are 380 V or 220 V. Motor power and electrical configuration may vary by model/configuration, so confirm the specific unit details with the manufacturer.

3. What are the main working dimensions (stroke, opening height, throat depth, table size)?

Standard dimensions listed are: slide stroke 360 mm, maximum opening height 500 mm, throat depth 200 mm, and working table size 400 × 500 mm.

4. What are the ram speeds (descending and return)?

Two speed options are shown in the spec table: descend speed 12 mm/s or 21 mm/s; return speed 19 mm/s or 32 mm/s. Actual speed depends on the chosen configuration.
