[Three rain valve to recommend the star product - Mechanical seal] Introduction: mechanical seal to ensure low leakage rates even to achieve zero leakage, then end clearance to be small enough. And so by the end surface roughness, parallelism and installation factors UK1250 mechanical seal, dynamic and static ring face is likely to collide or rub UK2500 mechanical seal, so the study of friction conditions between the end faces is very important. During normal operation the mechanical seal, due to the different sealing medium, internal structure and operating conditions (speed, pressure, temperature, etc.), according to the hypothesis viscous force, may occur between the seal faces of the following four kinds of friction state. [Three rain valve to recommend the star product - Mechanical seal] Introduction: mixed friction. With the decrease of the end surface waviness, static ring end clearance becomes smaller, locally raised at this time neither support UK3250 mechanical seal dry friction, but also the lack of boundary friction nanoscale uniform surface texture, but contact between the surface At the same time there has been friction over several states exist mixed friction situation. Actual operation in the industrial field, the vast majority of ordinary mechanical seals work in mixed friction conditions, and only in light-load, high-speed or high-viscosity conditions of the machine will be in the whole film sealing fluid lubrication friction. GB mechanical seal selected three rain (Figure), UK2875 mechanical seal, Ma'anshan mechanical seal is provided by three rain Valve Co., Ltd. of Tianjin. Valve Co., Ltd.
