Abstract
The invention relates to a pumping ring for a series connection type mechanical sealing device for a pump. Through holes (63) are distributed on the circumference of a pump ring part (61) of the pumping ring, and grooves (65) open to the left side are further arranged to correspond to every through hole (63). The pumping ring is simple in structure and convenient to manufacture. Effect can be simultaneously taken on blocking liquid in cavities on the left side and the right side of the pumping ring so as to perform pumping circulation, flowing performance of blocking liquid in the mechanical sealing cavities is improved, and impurity accumulation is avoided.
Description
Technical field
What the present invention relates to is the mechanical seal for pump device, particularly the pump pumping ring of tandem mechanical seal device.
Background technique
Pump comprises a pair of spring type mechanical sealing device with the tandem mechanical seal device, axle sleeve, internal gland, outer gland, moving ring assembly and the axle sleeve of two-stage spring type mechanical sealing device are connected, the static components of two-stage spring type mechanical sealing device is connected with internal gland and outer gland respectively, internal gland and outer gland are docked at the pump housing and dock, in order to prevent that medium in the pump chamber is to external leakage, offer resistance sealing liquid pass liquid hole outside on the gland, in secondary mechanical seal chamber, inject the resistance sealing liquid, the resistance sealing liquid is taken away the fricative heat of secondary mechanical seal simultaneously, namely secondary mechanical seal chamber is lowered the temperature, in order to reach fruit of cooling, have at pump housing peripheral hardware recycle pump according to the operating mode needs resistance sealing liquid is carried out pump circulation heat radiation, the fixedly connected pumping ring that arranges on the moving ring assembly of secondary mechanical seal is also arranged, the resistance sealing liquid liquid outlet opening that the corresponding external pressure of pumping ring covers is by the heat radiation that circulates outside pump of the resistance sealing liquid in the pumping ring effect secondary mechanical seal chamber.
Prior art pumping ring is to offer L shaped groove structural type in the outer ring surface distribution of pumping ring, or distribute at pumping ring circumference and to offer the through-hole structure form, 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, namely 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, the pumping ring of a kind of pump with the tandem mechanical seal device is provided
,Improving the resistance sealing liquid circulating effect in the Seal cage, and easy to implement, and cost is low.
The present invention offers through hole 63 in pump ring portion 61 circle distribution of pumping ring, and corresponding each through hole 63 also has the groove of opening to the left 65 in pump ring portion 61; Its right end face in pump ring portion 61 offers seal groove 67.
The present invention is simple in structure, and is easily manufactured.The fixedly connected pumping ring that arranges on the spring tailstock of the moving ring assembly of secondary mechanical seal, resistance sealing liquid liquid outlet opening and gland internal chamber wall on the pump ring portion 61 corresponding glands of pumping ring are slidingly matched.The through hole of offering in pump ring portion 61 circle distribution of pumping ring 63 and the groove of opening to the left 65, when pumping ring rotation work, the resistance sealing liquid in secondary mechanical seal cover 5 inner chambers of chamber, the pumping ring 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 is fully circulated, the heat in chamber, pumping ring left side also can be pulled away by resistance the mobile of sealing liquid, effectively prevented simultaneously chamber, pumping ring left side accumulated impurity, the mechanical seal safe operation has been produced harmful effect.
