Abstract
The utility model provides a mechanical seal device for a pump. The mechanical seal device comprises a spring base arranged on a transmission shaft and is characterized in that the spring base is connected with the transmission shaft through a spline, the spring base is connected with a moving ring base which is provided with a moving ring, the moving ring base is tightly pressed through a spring inside the spring base, a stationary ring is arranged on the transmission shaft, and the outside of the stationary ring is connected with a gland. According to the mechanical seal device, when transmission of the spring base is designed, conventional transmission achieved through set screws is not adopted, a spline groove designed in an inner hole of the spring base is matched with the spline on the shaft so as to achieve transmission, therefore, space is saved, and the requirement for driving force is met.
Description
technical field
The utility model relates to a kind of Sealing, is specifically related to a kind of mechanical sealing device used for pump.
background technique
Mechanical seal for pump refers to that installation and operation plays the device of dynamic sealing action in pump apparatus, avoids the flowing medium in water pump spiral casing to flow out a kind of parts outside water pump by pump shaft; Generally by rotating ring, stationary ring, seal ring of moving ring, stationary ring seal ring, spring, spring seat, Cock screw, stop pin etc., formed.During mechanical seal work, the axial force being caused by the elastic force of fluid-encapsulated pressure and elastic element etc. makes rotating ring and stationary ring laminating relative movement mutually, due to closely cooperating of two seal faces, make the boundary (seal interface) between seal face form a micro-gap, when having piezodielectric to pass through this gap, form liquid film as thin as a wafer, produce resistance, stop dielectric leakage, liquid film makes again end face be lubricated simultaneously, obtains long term seal effect.Common mechanical seal, owing to being subject to the impact of the mode between its structure member, often realizes by complicated structure annexation when it requires driving force large, installs and manufactures all inconveniences.
summary of the invention
The purpose of this utility model is that the problem for above-mentioned existence provides a kind of mechanical sealing device used for pump, and simple in structure, driving force is large, install manufacture simple.
Above-mentioned object realizes by following technological scheme:
Mechanical sealing device used for pump, comprise the spring seat being arranged on transmission shaft, described spring seat and transmission shaft pass through spline joint, described spring seat connects rotating seat, on described rotating seat, rotating ring is installed, stationary ring, by the rotating seat described in spring compression, is installed on described transmission shaft in described spring seat the inside, and described stationary ring outside connects gland.
Described mechanical sealing device used for pump, is provided with stationary ring seal ring between described gland and described stationary ring.
Described mechanical sealing device used for pump, is provided with seal ring of moving ring between described rotating ring and described transmission shaft.
Described mechanical sealing device used for pump, is connected snap close between described spring seat and described rotating seat.
Beneficial effect:
1. the utility model is when design spring seat transmission, do not adopt traditional with Cock screw transmission, in the transmission of spring seat bore design spline fitted shaft upper spline, so to have saved space, met again driving force large.
2. the utility model is when design spring seat drives rotating seat transmission, and spring seat has designed 3 snap closes and driven the transmission of rotating seat blade, and driving force is large.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, spring seat, 2, transmission shaft, 3, rotating seat, 4, rotating ring, 5, spring, 6, stationary ring, 7, gland; 8, stationary ring seal ring; 9, seal ring of moving ring.
