SKU: N/A Category: Tags: , , , ,

The TC-4830 Automatic Hydraulic Power Pack, dual stage, controlled by BC 100 is designed to supply the required oil to the load frames for loading. The power pack is very silent, even at full load and can load the specimen between 1 kN/sec. to 20 kN/sec, with an accuracy of ±5%. A rapid approach pump is supplied as standard. A safety valve (maximum pressure valve) is used to avoid machine overloading.
The TC-4840 Automatic Hydraulic Power Pack, dual stage, controlled by BC 100 has the same specifications with TC-4830 except for high oil capacity. TC-4840 is used on frames that has bigger pistons. Maximum working pressure of the system is 430 bar.

Dual Stage Pump

  • Low pressure gear pump
  • High pressure durable variable output pump

On the dual stage pump, a high delivery low pressure gear pump is used for rapid approach, while low delivery high pressure radial piston pump is used for test execution. Rapid approach facility of the machine shortens the time interval from when the piston starts moving until the upper platen touches to the specimen, this facility saves a great amount of time in a busy test laboratory.

Motor

The motor which drives the dual pump is a 0.75 kW AC motor which is controlled by an Omron J7 motor inverter. The variation in the oil flow is executed with the variation of the rotation speed of the motor.

Distribution Block

Distribution block is used to control the oil flow direction supplied by the dual stage pump and the following hydraulic components are fitted to it:

  • Solenoid Valve
  • Safety valve (maximum pressure valve)
  • Transducer
  • Low pressure gear pump
  • High pressure radial piston pump

Oil Tank

The tank includes enough oil to fill the mechanism which pushes the ram during the test. The level and oil temperature can be seen on the indicator fitted to the tank. The oil capacity of the tank is 20 litre. for TC-4830 and and 32 litre. for TC-4840. Hydraulic motor oil, number 46, must be used.
