Abstract
The utility model relates to a liquid conveying pipe line pump. The sealing seat, the sealing and the shaft guiding bearing of the pump are simultaneously arranged at the upper end of a pump cover and a sealing chamber isolated from the conveying medium is formed. When the sealing or shaft guiding bearing is needed to be exchanged, the user only needs to dismount a shaft connecting device. The mounting and the dismounting can be conveniently carried out through the gap between the shaft of an electric motor and a pump shaft and the maintenance time is saved. Simultaneously, the sealing working can not be affected by the conveying medium because the sealing chamber structure isolated from the conveying medium is adopted. The service life of the sealing is extended and the operational reliability of the pump is increased.
Description
The utility model relates to the pump class of carrying liquid medium, particularly to the improvement of pipeline mounted pump.
Pipeline mounted pump is a kind of vertical pump, and the import and export center is on the same vertical line of pump shaft.The pipeline mounted pump compact structure can be directly installed in the pipeline, and floor space is little, can reduce pipeline fittingses such as valve, bend pipe, has not only saved the large number quipments expense, and has improved the operational efficiency of pump-unit.Because pipeline mounted pump has above-mentioned advantage, therefore, use increasingly extensively in recent years, the trend that replaces common centrifugal oil pump is arranged in the oil stockpile system especially.The sealing of pipeline mounted pump and guide bearing are the key parts in addition in decision pump work reliability and working life, need maintenance on time or replacing.Existing pipeline mounted pump (structure such as Fig. 1) is changed sealing or guide bearing as need, and the part in addition such as motor wiring, coupling, motor, motor base (frame), pump cover, impeller of must dismantling is so maintenance load is big.If in inflammable, explosive environment, occur spark during dismounting easily or static takes place and cause accidents such as burning, blast.In addition, the pipeline mounted pump of prior art is when the liquid that conveying is easy to volatilize, and steam is easy to accumulate in the Seal cage, at this moment, is sealed under unlubricated, the non-refrigerated condition and works, and is easy to damage.
The purpose of this utility model is that a kind of dismounting sealing of design or guide bearing are convenient, simple in structure, the pipeline mounted pump of long service life.
In order to achieve the above object, the utility model utilizes the through hole of the motor base (frame) of prior art also to be enlarged, and makes it to form a frame structure, allows sealing seat expose;
Motor reel adopts the separable type coupling to connect with pump shaft, makes and forms the gap that can allow sealing seat, sealing, guide bearing therefrom pass through between two, so that can be by this gap transposing sealing or guide bearing;
In order to install and remove sealing and guide bearing easily, the utility model designs sealing, guide bearing and sealing seat on pump cover;
Seal working life in order to improve, its sealing seat is a hollow structure, locatees on pump cover with seam, cooperate, be connected with pump cover with bolt with flanged surface, above it be sealed and matched, go to the bottom and guide bearing joins, make it to form a Seal cage isolated with fed sheet of a media;
The guide bearing central upper portion has one the garden groove of sealing is installed, and adopts flanged surface and seam and pump cover formation plane and garden cylinder to locate simultaneously, based on the junction plane on plane, or locatees with the garden cylinder with pump cover;
For ease of the sealing seat dismounting, the tapped through hole 10 in that symmetry more than two is arranged on the sealing seat flanged surface in the time will dismantling sealing seat, is screwed into bolt, and sealing seat and pump cover are broken away from.
Have following characteristics through the pipeline mounted pump after the above-mentioned improvement design:
1. when transposing sealing and guide bearing, can not dismantle component such as motor, electric wiring, motor base (frame), the pump housing, impeller and pipeline, easy to maintenance, save time, improve the pump effective time, especially in inflammable, explosive environments, make the work of pump house safer, reliable;
2. owing to adopted the Seal cage structure of isolating with fed sheet of a media, the work of sealing is not subjected to the influence of fed sheet of a media, has prolonged the working life of sealing and the reliability of pump work.If use double mechanical seal, can approach not have and leak, carry inflammable, explosive, poisonous, corrosion is arranged or has more significance during the medium that is easy to pollute.
If the utility model can be used for the oil stockpile system adapted permissible motor and other explosion precaution, as oil product can, supercharging, carry, unload groove etc.
