Slurry pump mechanical seal

Exit} pupil body wash; 3. Steam inlet and outlet for the concentration of dissolved solids less than 5% of the dissolved transition, often using single mechanical seal. On the concentration of 5 ~ 1O% of the dissolved solids solution, can be a single face, metal bellows seal, friction of silicon carbide tungsten carbide materials, in order to prolong life, clearance to use the rinse water. Concentration of dissolved solids of more than lO% solution, need special treatment, to continuously flush, dual-end or tandem mechanical seals. 4. Inductive solution with mechanical seal heat in recent years, single-ended and mechanical seals and double mechanical seal used in this area better. The most fundamental point is to ensure that the solution does not solidify, in a flow state. ∞ curing or thickening products may cause transmission parts wear plus just,[link widoczny dla zalogowanych], sports blocked and a 37 - Figure 8 paint (rubber) pump mechanical seal 1. Car park in front of the solvent after the opening to the cavity quality of the village note Figure 9 (France) CPA mechanical seal 1. Diaphragm spring; 2. Nuts; 3. Diaphragm by adjusting the sleeve to adjust the spring tension of a good three-s: To ////> Figure 10 (USA) BorgWarnerRIS mechanical seal 1. Static ring assembly; 2. Stationary ring seat; 3. Ring components; 4. Impeller hub; 5. Bearing; 6. Gland; 7. Elastic ring face destruction. Correctly driving inductive solution and heating is hot sealed key to success. In general, this solution, driving 2-3 hours before the equipment should be warm. At the same time, often in a sealed chamber and gland region heated by steam or hot medium, as shown in Figure 7, paint and rubber and the like on the high viscosity, solidified strong attachment solution, often using linear seal. Friction blade designed for a face, edge width 0.5ram. It can result in higher than face pressure to cut off the sealing surface solidification, liquid paint adhesion (or glue), so as to ensure the reliability of sealing. End result is a blade, on the thermal deformation, pressure deformation is not sensitive, with good fit, shown in Figure 8. Third, the development trend of particle slurry seal in the aluminum industry, the hardness of particles is high, medium a 38 for a loss of rot,[link widoczny dla zalogowanych], highly abrasive, sealed very harsh conditions, more recent studies abroad. The early 80s, the French Ministry of AlnminumPeehiney factory test for bauxite, aluminum hydroxide suspension, designed diaphragm seal, shown in Figure 9. The general mechanical seals with different sealing, with the diaphragm spring instead of the general spring,[link widoczny dla zalogowanych], but also eliminates the need for secondary seals. Belleville spring diaphragm spring out from the coating of chloroprene rubber (or neoprene or PTFE) composition. Its role is to make the ring close to the stationary ring,[link widoczny dla zalogowanych], ring to ensure no leakage between the seat and the sleeve to compensate static ring and the vertical axis of rotation degree is not asked. The mechanical seal does not require washing, pumping medium can not be diluted, thus saving energy. Not only reduces operating costs, but also reduces the overall equipment investment. It is easy to install, easy to adjust, the service life of over 2 years. In addition it has proved suitable for chemical fertilizer industry, metallurgy, sugar and paper. American Institute of Mechanical Seals for BorgWarner has developed a new aluminum case of the mud pump mechanical seal. The mechanical seal (see Figure 10) with a flexible ring, both as an aid for the springs and seals, to avoid congestion caused by sliding with or impeded. This seal is very easy to install and adjust. Rinse to remove water from the slurry diluted to achieve the purpose of saving afraid. Meanwhile, the mechanical seal assembly uses a special technique in the operation of the pump seals can also be adjusted. Replace the seal, the need to disassemble the entire pump. When the pump is running,[link widoczny dla zalogowanych], but also adjust the impeller wear ring gap, without affecting the seal installation. Therefore, very practical. Power won disk (HDs) ~ A centrifugal seal since the seventies has been applied in granular media access to a larger success. When the shaft rotates, the fluid pressure generated by centrifugation, and the pump casing channel cochlear fluid flow to seal leaks in the opposite direction, when the pressure and leak pressure are equal, which can be sealed to prevent leakage when the shaft stationary, HDS does not seal , need to add static secondary seal. HDS big drawback is power consumption. References [1] A. I. Golubiev so, InvestigationofwearinMechanicalSealsinLiquidsContainingAbra-sirePartlcles. 7thIntermtionalConferSliCeonFluidSealing1975.
