Prior art pumping ring is to distribute to offer L shaped groove structural type on the outer ring surface of pumping ring, or the through-hole structure form is offered in distribution on pumping ring circumference, these two kinds of structure working principles are identical, the centrifugal force that rotation by the pumping ring produces, the resistance sealing liquid that enters pumping ring L groove or through hole is carried out the centrifugal pumping effect, send from the resistance sealing liquid liquid outlet opening that external pressure covers.
The shaft sleeve part cooperation of prior art pumping ring is fixedly mounted on the tailstock of secondary mechanical sealing linkage ring assembly, the pump ring portion outer surface of pumping ring and external pressure cover cavity wall are slidingly matched, two chambers about the tailstock of pumping ring and moving ring assembly is divided into the external pressure cover cavity, about this, all be filled with the resistance sealing liquid in two chambers, promptly in primary seal rear portion and secondary seal chamber, all be full of the resistance sealing liquid, and the L groove of pumping ring or through hole externally the right part chamber in the gland work, the resistance sealing liquid only circulates in the right-side cavity of pumping ring, and the chamber, left side of pumping ring resistance sealing liquid can not get circulation, the heat in chamber, pumping ring left side can not be pulled away by resistance the mobile of sealing liquid, and chamber, pumping ring left side is closed state for a long time and is easy to accumulated impurity, and the mechanical seal safe operation is produced harmful effect.
Summary of the invention
The objective of the invention is to improve at above-mentioned the deficiencies in the prior art, a kind of pump tandem mechanical seal device and pumping ring thereof are provided, to improve to the resistance sealing liquid circulating effect in the Seal cage, resistance sealing liquid in the Seal cage is fully circulated, improve radiating effect, and easy to implement, cost is low.
The present invention includes one-level spring type mechanical sealing device 1, two-level spring formula mechanical seal device 2, axle sleeve 3, internal gland 4, outer gland 5, the moving ring assembly of two-stage spring type mechanical sealing device and axle sleeve 3 are connected, the static components of two-stage spring type mechanical sealing device is connected with internal gland 4 and outer gland 5 respectively, internal gland 4 and outer gland 5 are docked at the pump housing and dock, offer resistance sealing liquid inlet opening 50 and liquid outlet opening 51 outside on the gland 5, the fixedly connected pumping ring 6 that is provided with on the spring tailstock 22 of the moving ring assembly 21 of secondary mechanical seal 2, resistance sealing liquid liquid outlet opening 51 on the pump ring portion 61 corresponding outer glands 5 of pumping ring 6 is slidingly matched with gland 5 internal chamber walls, it is characterized in that, pump ring portion 61 circle distribution at pumping ring 6 offer through hole 63, and corresponding each through hole 63 also has the groove of opening to the left 65 in pump ring portion 61; Corresponding spring base hole 24 has water conservancy diversion through hole 25 on the spring tailstock 22 of the moving ring assembly 21 of secondary mechanical seal; Stationary seat portion 41 corresponding distributions near static friction ring 43 rearward end at internal gland 4 offer the water conservancy diversion through hole 45 that leads to gland 5 inner chamber outer portion.
The present invention is simple in structure, and is easily manufactured.Through hole of offering in pump ring portion 61 circle distribution of pumping ring 6 63 and the groove of opening to the left 65, when pumping ring 6 rotation works, the resistance sealing liquid in gland 5 inner chambers outside the chamber, pumping ring 6 left and right sides can be acted on simultaneously and carry out pumping circulation, the resistance sealing liquid in the chamber, left side of pumping ring 6 is fully circulated, the heat in chamber, pumping ring 6 left side also can be pulled away by resistance the mobile of sealing liquid.Simultaneously, owing on the spring tailstock 22 of the moving ring assembly 21 of secondary mechanical seal, have the mobile performance that water conservancy diversion through hole 25 has effectively improved chamber, the left side resistance sealing liquid of pumping ring 6, and the spring base hole 24 that can effectively prevent secondary mechanical sealing linkage ring assembly 21 stores foreign material, cause the compensation performance of spring base hole 24 congestion affects springs, effectively prevented simultaneously chamber, pumping ring left side accumulated impurity, the mechanical seal safe operation has been produced harmful effect.The water conservancy diversion through hole of offering in the stationary seat portion 41 of internal gland 4 45 further improves the flowabilities of the resistance sealing liquid of the one-level mechanical seal rear chamber that is communicated with secondary mechanical seal chambeies.
