The H7N series mechanical seals are widely used, with strong interchangeability and compact structure. The static ring adopts floating type and is easy to install. The push ring is mainly stuck by the transmission tower to prevent the spring from falling off. Reliable performance, widely used in petrochemical pumps. This series of mechanical seals are generally used under low pressure conditions. The elastic compensation element of H7N series mechanical seals is a waveform spring, which has the advantages of short axial size, strong resistance to blockage, resistance to elastic failure, etc. Generally applicable to the conditions containing solid particles. The elastic compensation element of H74 series mechanical seals is a small spring, and the elastic source side is exerted by a number of small springs together. Its advantage is that the sealing surface is stressed evenly. The F of H7F and H74F series mechanical seals refers to the spiral groove structure of the spring seat cylindrical processing, its role is to use the pumping spiral effect to accelerate the flow of liquid, so as to reduce material accumulation, but also conducive to the rapid cooling of the sealing surface burned off prematurely. The driving mode of M7S2 and M74S2 series mechanical seals is deeply dependent on the key drive, and the key drive can be used when the axle diameter is more than 100mm, and its function is to drive more reliably. H75 series mechanical seal is equivalent to H74 mechanical seal, this structure is suitable for the occasion of large axial channeling momentum. H76 SERIES mechanical seal deep single spring structure, suitable for the occasion of greater axial channeling momentum.
