German-style hose clamps use an open outer ring structure tightened with bolts. This design effectively eliminates dead corners and prevents liquid or gas leaks in small-diameter hard/soft pipe connections. It is widely used for securing water pipes, hoses, and similar pipeline products.
The external pressure ratio of a German-style clamp is the ratio of exhaust pressure to intake pressure in stainless steel clamps. Internal resistance causes the actual exhaust pressure to fall below atmospheric pressure, while the actual intake pressure exceeds the system’s supply pressure. The internal pressure ratio (actual exhaust pressure ÷ actual intake pressure) determines energy efficiency: the closer this ratio aligns with the external pressure ratio, the more energy-efficient the system becomes .
Low-speed operation in German-style clamps reduces energy consumption by:
1.Enlarging intake/exhaust ports to lower airflow velocity.
2.Minimizing internal pressure ratios.
During compression, input power converts to heat, sharply raising gas temperatures and power demands. However, ideal compression maintains stable temperatures despite pressure increases. To mitigate heat, German-style clamps inject oil during compression, slowing temperature rise. The extended heat exchange time at low speeds ensures near-perfect oil-gas thermal transfer, keeping temperatures low. This process significantly reduces power consumption compared to high-speed clamps and extends lubricant lifespan.
