Undercarriage parts for excavator and bulldozer

Multifunction Compact Diaphragm Accumulators to supply the Undercarriage and excavator ,bulldozer , extraction industry.

Using an accumulator as an energy storage device effectively reduces the required flow rate capacity of the hydraulic pump, this results in a reduction of the installed power.The energy stored in an accumulator is used to avoid the accidental interruption of the working of the power generator by guaranteeing continuity of the safety function for a specific time.An accumulator which is kept constantly under pressure allows for instant and/or repetitive operations as required (braking, opening of doors etc).An accumulator on account of the low inertia of its bladder can dampen the pulsations generated by the pump.

Compact, light weight ,economical design. These hydro-pneumatic accumulators are constructed of two forged steel hemispherical sections welded together by a hi-tech electron beam welding process. This assures the customer a strong, safe and reliable design.

In many hydraulic systems there is the need to either store energy, compensate fluid level changes or absorb shock. In order for the accumulator to function properly, a high compressible medium (Nitrogen) and a non compressible medium (Hydraulic fluid) are separated by a rubber diaphragm.
