South Korea NARA speed control type hydraulic coupler

1, NARA co., LTD (South Korea) was established in October 1979, specializing in the production of elastic coupling

April 2, 1986 successfully developed the torque-limiting type hydraulic coupler

Developed in April 3, 1997 for diesel engine at low speed of the rotary gear reducer, planetary reducer

4, in September 1997 and signed a contract with mitsubishi heavy industries of Japan, become the OEM suppliers

September 5, 2001 for K9 cannon was developed successfully high speed hydraulic coupling

6, in June 2004 for K1 tanks was developed successfully hydraulic control valve

July 7, 2004 successfully developed speed control type hydraulic coupler

"Now the NARA, South Korea has become the largest hydraulic coupling manufacturer"

Basic principles:

For most of the centrifugal machine, when they were in the design and operation at low load conditions, the average size is too big, many of them need frequent adjustment in operation process. So you need to use some low efficiency of the device, such as: buffer or control valve;

NARA addition speed (type growth/slow sex/limited moment) hydraulic coupling, by controlling the thickness of the oil ring, can realize stepless speed regulation (25% 100%), thus saving energy, and may make the related equipment longer life.

NARA industrial advantage of speed control type hydraulic coupler:

1, energy saving

2, no-load start can be realized

3, stepless speed regulation

4, shock and impact

5, can be manual or automatic remote adjusting speed (speed can be adjust)

6, can make the need to minimize the input power

7, from the motivation of easy maintenance, the machine good abrasion resistance, low operating noise
