Abstract

The utility model provides a mechanical sealing device special for a rotary jet pump, which comprises a movable assembly and a static assembly. The movable assembly and the static assembly are sleeved in a shell. The movable assembly is composed of a movable ring seat and a movable friction ring. The movable friction ring is embedded in the movable ring seat. An O-shaped sealing ring is embedded between the movable ring seat and the shell. The static assembly is composed of a static ring seat, a static friction ring, a spring and a spring seat. The static ring seat is embedded in the spring seat. The closed side of the static ring seat is elastically connected with the spring seat by means of the spring. The opened side of the static ring seat is embedded with the static friction ring. The static friction ring abuts against the movable friction ring. An O-shaped sealing ring is embedded between the spring seat and the shell. Since the static friction ring and the movable friction ring together form a working surface, the medium in the pump is prevented from leaking to the outside. When a gap is formed between the opposite working surfaces of the static friction ring and the movable friction ring due to the abrasion of the working surfaces, the static ring seat is pushed by the spring so as to move the static friction ring towards the movable friction ring. Meanwhile, the static friction ring is driven to abut against the movable friction ring, so that the sealing effect is realized. Therefore, the service life of the rotary jet pump is prolonged.

Description

Rotary jet pump mechanical seal device
Technical field
The utility model relates to a kind of mechanical seal device, relates in particular to a kind of rotary jet pump mechanical seal device.
Background technique
Due to rotary jet pump, there is the advantages such as small flow, high-head, nothing leakage, be widely used in the industries such as oil, chemical industry, chemical fertilizer, metallurgy, mining, especially in chemical process flow, as chemical-process transfer pump, current existing rotary jet pump mechanical seal structure more complicated, long-time use not only needs mechanical seal structure to rinse, and also can cause serious wearing and tearing to sealing configuration, thereby reduce the effect of sealing, shorten the working life of rotary jet pump.
Summary of the invention
The utility model provides a kind of rotary jet pump mechanical seal device, and object is to solve prior art problem, provides a kind of simple in structure, install fast and convenient, good seal performance, the rotary jet pump mechanical seal device of durable wear.
The utility model technological scheme adopting of dealing with problems is:
Rotary jet pump mechanical seal device, it is characterized in that: there is moving assembly and quiet assembly, moving assembly and quiet assembly are set in housing, moving assembly is comprised of rotating seat and kinetic friction ring, kinetic friction ring is embedded in rotating seat, between rotating seat and housing, be embedded " O " RunddichtringO, static components is by stationary seat, static friction ring, spring and spring seat form, stationary seat is embedded in spring seat, between one side of stationary seat sealing and spring seat, by spring, be connected, the open side of stationary seat is embedded static friction ring, static friction ring and kinetic friction ring contact, between spring seat and housing, be embedded " O " RunddichtringO.The top of described stationary seat is provided with collar, and collar is embedded the inwall into spring seat top.The bottom of described stationary seat is embedded with " O " RunddichtringO, and " O " RunddichtringO contacts with the inwall of spring seat bottom.
The beneficial effects of the utility model: the static friction ring and the kinetic friction ring that are provided with due to the utility model form a working surface, can stop the medium in pump to leak, when the opposing side wearing and tearing of kinetic friction ring and the work of static friction ring produce gap, owing to there being spring to promote stationary seat, reaching static friction hoop kinetic friction ring moves, and with kinetic friction ring contact, thereby reach the effect of sealing, extend the life-span of rotary jet pump.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model.
In figure: 1, moving assembly; 2, quiet assembly; 3, rotating seat; 4, kinetic friction ring; 5, " O " RunddichtringO; 6, stationary seat; 7, static friction ring; 8, spring; 9, spring seat; 10, " O " RunddichtringO; 11, collar; 12, " O " RunddichtringO.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Rotary jet pump mechanical seal device as shown in Figure 1, described mechanical seal device is installed between the import and export section and pump cover of medium of rotary jet pump, there is moving assembly 1 and quiet assembly 2, moving assembly 1 and quiet assembly 2 are set in housing (not shown), moving assembly 1 is comprised of rotating seat 3 and kinetic friction ring 4, kinetic friction ring 4 is embedded in rotating seat 3, between rotating seat 3 and housing (not shown), be embedded with " O " RunddichtringO 5, and by the gap between " O " RunddichtringO 5 moving sealing ring seats 3 and housing (not shown), static components 2 is by stationary seat 6, static friction ring 7, spring 8 and spring seat 9 form, stationary seat 6 is inserted in spring seat 9, between one side of stationary seat 6 sealing and spring seat 9, by spring 8 elasticity, be connected, the two ends of spring 8 are contact spring seat 9 and stationary seat 6 respectively, stationary seat 6 open sides are embedded with static friction ring 7, static friction ring 7 and kinetic friction ring 4 contacts, the surface of contact of contact forms a working surface, because static friction ring 7 and the close contact of kinetic friction ring 4 contacts make the medium in pump be not easy to leak, between spring seat 9 and housing (not shown), be embedded " O " RunddichtringO 10, and by the gap between " O " RunddichtringO 10 Packing spring seats 9 and housing (not shown), the top of stationary seat 6 is provided with collar 11, collar 11 is embedded the inwall into spring seat 9 tops, can play spacing effect, restriction stationary seat 6 is subjected to displacement, the bottom of stationary seat 6 is embedded with " O " RunddichtringO 12, " O " RunddichtringO 12 contacts with the inwall of spring seat 9 bottoms, also play the friction factor increasing between stationary seat 6 and spring seat 9, prevent from being moved between stationary seat 6 and spring seat 9.
When the opposing side wearing and tearing of kinetic friction ring 4 and 7 work of static friction ring produce gap, 8 pairs of stationary seat 6 applied thrusts of spring, make stationary seat 6 to moving away from one end of spring 8, stationary seat 6 promotes static friction ring 7 also to moving away from one end of spring 8 when moving, thereby make static friction ring 7 close to kinetic friction ring 4, and contact contact kinetic friction ring 4, thus reach the effect of sealing, extend the life-span of rotary jet pump.
During use, spring seat 9 is connected between the import and export section and pump cover of medium of rotary jet pump, " O " RunddichtringO 10 is contained on the disk of spring seat 9 tail ends, in spring eye in spring seat 9, pack spring 8 into, " O " RunddichtringO 12 is embedded in the annular groove of stationary seat 6 inside, the stationary seat 6 that is embedded with static friction ring 7 is pressed in spring seat 9, with collar 11, spring seat 9 and stationary seat 6 are fixed together and form quiet assembly 2 again, " O " RunddichtringO 5 is set on rotating seat 3, by the pin hole on moving assembly 1, moving assembly 1 is fixed on the end face of rotor disk, static friction ring 7 and kinetic friction ring 4 contacts after installing, the sound assembly of mechanical seal is located at pump cover and imports and exports in the seal chamber forming in section pump, kinetic friction ring 4 and the static friction ring 7 of mechanical seal are closely linked, formed the working surface of a sealing, the moving assembly 1 of rotation driving mechanical sealing by rotor rotates together, after end wear, can produce certain gap, by the spring 8 being provided with in spring seat 9, promote stationary seat 6, allow kinetic friction ring 4 and static friction ring 7 state in combining closely always, can not cause the leakage of medium.
