Abstract
The utility model provides a static ring adjustable mechanical seal device which is characterized in that a static ring and a dynamic seal ring are nested on a rotary shaft, and a pressed cover is fixed on a shell so that the mechanical seal device is constructed; a static ring seal ring is nested on the static ring and matched with a static ring base; the front end surface of a thread adjusting sleeve nested on the rotary shaft is supported on the static ring base; a support ring is nested on the static ring base; the upper segment inner ring of the support ring is in threaded and buckling matching with the thread adjusting sleeve and tightly fixed through a locking nut mutually; the pressed cover is nested on the support ring and fixed tightly on the end surface of the shell through a bolt. Seal rings are respectively arranged on the annulus surfaces between the static ring base and the support ring, and between the support ring and the shell. The technical proposal of the utility model includes that the ring dynamic and static sealing modes between the rotary shaft and the shell form the ring static seal through two seal rings so that the sealing effect is improved obviously. The static ring adjustable mechanical seal device has the advantages of saving energy, reducing consumption, prolonging maintenance period and improving the efficiency of the mechanical equipments.
Description
Technical field
The utility model belongs to seal arrangement, particularly relates to the adjustable mechanical seal device of a kind of stationary ring.
Background technique
The stationary ring of existing mechanical seal arrangement all is nonadjustable, because mechanical seal is easy to generate leakage at work, does not have and adjusts, and causes maintenance frequent, and recondition expense increases.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, provides a kind of stationary ring adjustable mechanical seal device.
The adjustable mechanical seal device of stationary ring of the present utility model is to be fixed on the housing and to constitute being with stationary ring, rotary packing ring and gland on the rotatingshaft, on stationary ring, be with the stationary ring seal ring, and and stationary seat movingly, the front-end face that is enclosed within the threaded adjustment cover on the rotatingshaft is butted on the stationary seat, support ring be placed on the stationary seat and its epimere in ring and threaded adjustment overlap mutual spiral shell and buckle and cooperates, have locking nut that it is fastening mutually, have gland to be placed on the support ring and by bolt tightly on the end face of housing.
As further improvement of the utility model, the anchor ring between anchor ring between stationary seat and the support ring and support ring housing is equipped with seal ring.
As further improvement of the utility model, the locking pin is all arranged at the end face of stationary ring and the outer side surface of stationary seat.
Utilize device of the present utility model, when seepage occurring, regulate the threaded adjustment cover and promote stationary ring, thereby increase the tightness of stationary ring and rotating ring, stop a leak, realize sealing by stationary seat.
The technical solution of the utility model is with the annular dynamic and static sealing means between axle and housing, has constituted annular static seal by two seal rings, has significantly improved sealing effect, have energy-saving and cost-reducing, prolong the repair cycle, improve advantage such as moving device efficiency.
