Flexible design; several boosters/intensification factors

Switch from by-pass to intensified flow

Description

The M-HC-011 In-line Intensifier System is designed to boost the hydraulic pressure from the pump to the workload. It operates only when needed, to save energy.

The system is dynamical by means of being able to provide flow at high pressure for intermittent use (< 10 min duty cycle).

Typical applications

Mobile attachments; motors – steering systems – cutters – crushers – shears, off highway equipment, injection molding machines and hydraulic presses. Applicable to machines with insufficient pump capacity to prevent machine stoppage when peak pressures occur.

Easy installation

M-HC-011 is provided with four mounting holes for through bolt installation. The four connection ports are placed logically in pairs and in line of each other on the HIC block. All surfaces are electroplated for good protection and fine surface finish.

Functions

The function of the system is simple, but smart. The hydraulic oil is by-passed directly from the pump to the workload at maximum flow when back pressure from the workload has reached a set point close to the maximum pressure of pump.

A sequence valve opens and directs the oil to the booster, which makes the pressure rise. The shift between maximum pump pressure and high pressure happens without intervention from the user and ensures that the workload at all times will be driven at a maximum speed in relation to the required high pressure.

A relief valve is installed to control the maximum allowable pressure that the system can output, and allowing the booster to go for a higher end pressure producing flow at the decided pressure.

The intensification factor depends on available inlet and desired outlet pressure. To calculate the initial factor, use the following formular:

i = Desired high pressure / pump pressure

Desired pressure: 600 bar
Pump pressure: 200 bar
i = 600 / 200 = 3.0

For static use: Select an intensification factor higher or equal to the calculated value. In this example calculated i = 3.0, select factor i = 3.2 for an HC3 booster. The desired pressure of 600 bar is finally adjusted with the HP relief valve.

For dynamic use: Select an intensification factor 60% higher than the calculated value. In this example calculated i = 600 / 200 = 3.0 + 60% = 4.8, select factor i = 5.0 for an HC3 booster. The desired pressure of 600 bar is finally adjusted with the HP relief valve.
