German Sterling SIHI valves, Sterling SIHI models, Sterling SIHI prices
Sterling SIHI valves, also known as globe valves, belong to the forced-sealing valve category. Therefore, when the valve is closed, pressure must be applied to the disc to ensure a leak-tight seal. When the medium enters the valve from below the disc, the resistance that the operating force must overcome consists of the friction between the stem and packing, plus the thrust generated by the medium pressure. The force required to close the valve is greater than that to open it; hence, the stem diameter must be large enough to prevent bending failure. Connection methods are classified into three types: flange connection, threaded connection, and welded connection. Since the advent of self-sealing valves,
German Sterling SIHI pump, Sterling SIHI model, Sterling SIHI price
Sterling SIHI pumps operate by using impeller rotation to induce centrifugal motion in water. Before starting the pump, the pump casing and suction pipe must be filled with water. Then, start the motor to drive the pump shaft, causing the impeller and water to rotate at high speed. The water undergoes centrifugal motion, is thrown toward the outer edge of the impeller, and flows into the pump's discharge piping through the passages of the volute casing. The structure of an Sterling SIHI pump consists of six basic components: impeller, pump body, pump shaft, bearing, sealing ring, and packing gland. 1) The impeller is the core part of the centrifugal pump.
German Sterling SIHI seals, Sterling SIHI models, Sterling SIHI prices
Sterling SIHI seals are materials or components that prevent leakage of fluids or solid particles from adjacent mating surfaces and prevent external contaminants such as dust and moisture from entering machinery. The recommended storage temperature for seals is below 30 °C to avoid high-temperature aging. Seals are classified into two main categories: static seals and dynamic seals. Their primary function is to prevent leakage of fluids or solid particles from adjacent mating surfaces and to prevent external contaminants such as dust and moisture from entering machinery. Static sealing refers to tightly closing the sealed chamber.
