The limestone slurry pump valve packing technology

limestone slurry pump valve packing technology common sense

limestone slurry pump valve door many, as you know, the kinds of packing what common sense for the valve, the valve in the process of using leak is very pain is very dangerous, from leak prevention and control of the planning includes both volatile harmful substances leaked - — To avoid polluting the environment, also including steam and other languid is lazy in low temperature medium leak - — Avoid to produce power decrease.

assumption correct packing equipment, into radial stress by the axial stress in the attenuation of drops. It helps keep weaved in a longer time and reliable sealing function, and the reasonable load distribution conflict. On this basis, the valve leak sealing dissipation function, even produce power will increase obviously.

limestone slurry pump temperature limit

only at a certain temperature in the planning, packing and the performance of the sealing material talents with good function. Assumptions used in higher environmental temperature, its molecular structure is may change, lead to harmful gas leak, so that the valve stem corrosion attack, and even lead to toxic ptfe flue gas escaping from the top of the gland follower.

stuffing box is same to ensure clean without impurities and grease. Put a packing ring in a stuffing box, pay attention to the orientation of the interface, should first of all, the interface part into stuffing box, and then into the rest of the packing rings. Hypothesis is flexible graphite molded packing ring, shall each ring again after stretching into a spiral device in place, to avoid the packing ring damage. Each equipment a packing ring, ensure it is within the stuffing box after compaction and filled, a can device. Assuming that the length of the gland follower is not enough to reach the bottom of the stuffing box, the equipment packing ring needs tools or extended ring for temporarily.

for sealing ring and corrosion of the contact positions

different materials have different corrosion resistance, advising sealing ring material generally choose flexible rubber, and rubber is corrosion will make it very rough surface, after losing the original elasticity. And high temperature resistant function of the rubber is poorer, generally no more than two baidu, the limestone slurry water pump and advising seal contact area is relatively suspension, the gap and conflict between them will be the cause of the corrosion attack, and etched surface usually wider and deeper.
