Abstract
The utility model discloses a no-discharging pump with a fluoroplastics lining. The utility model is characterized in that on the basis of the no-discharging pump or an ordinary centrifugal pump body, over-current parts in a pump body, which are contacted with media, are all uniformly coated with fluoroplastic layers; levo threads for transferring force and a spline are arranged between an impeller and an impeller shaft to transfer torque. Simultaneously, the utility model discloses a mechanical seal which is used in a water supply device. In the mechanical seal, a moving ring and a stationary ring are sheathed to an assembly body which is inseparable along an axial direction; the stationary ring of a corrugated tube is provided with an elastic element. The utility model has the advantages of simple structure, convenient replacement and assembly, strong corrosion-resistant performance, strong wear-resistant performance, and strong seepage prevention performance.
Description
The utility model relates to a kind of pump that is suitable for carrying special fluid, is particularly suited for the non-leakage pump of high temperature strong corrosion environment.
Existing non-leakage pump is owing to due to its structure, can only select the pig iron, polyamine fat plastics, stainless steel manufacturing for use.And the corrosion resistant scope of these materials is very little, poor practicability.
The purpose of this utility model provides a kind of anticorrosive, anti abrasive fluoroplastics lining non-leakage pump, and it not only can be adapted to contain the molecule environment, but also can be applied to more powerful occasion.The mechanical seal that the utility model also provides a kind of general service pump and valve to be suitable for, it is simple in structure, manufactures easily, and good seal performance.
The purpose of this utility model is achieved in that on the basis of non-leakage pump or Ordinary Centrifugal Pumps body, to all evenly serve as a contrast system one deck fluoroplastic with the contacted overcurrent of medium position in the pump housing, open a ring recess at the rear portion of impeller shaft, in the tail end embedded groove of the fluoroplastics lining on the impeller shaft.Form sealing seam and rotating ring wedge, mechanical seal just is sleeved on both connection places, compresses the rotating ring wedge.Adopt power transmission left-handed thread and spline transmitting torque between impeller and the impeller shaft.The rotating ring of mechanical seal and bellows stationary ring adopt cemented carbide and macromolecular material to make respectively.And the two cover dressed up inseparable vertically total adult.One elastic element is set, in order to shrinkproof in the bellows stationary ring." V " RunddichtringO of bellows front end and taper close mouth embed in the rotating ring groove respectively and banding rotating ring front end, guarantee sealing effect.
The utility model has the advantages that:
1, simple in structure, install and change component conveniently.
2, pump liner system fluoroplastic, have very strong decay resistance.
3, because water inlet is a low pressure area at the axis hole place, deposit bits easily, the wearing and tearing sealing surface.The rotating ring of mechanical seal and bellows stationary ring adopt cemented carbide and macromolecular material to make respectively for this reason, " V " RunddichtringO and taper close mouth on bellows, have been designed, make its slit very little, molecule is difficult for invading, prolonged mechanical working life, and in the bellows stationary ring, be provided with elastic element, not only have very strong wear resistance.And the antiseepage corrosion protection result is remarkable.Be adapted to more powerful occasion.
