Abstract
A kind of Novel fluorine plastic pipe road pump, it relates to pump valve technical field.Comprise the pump housing of inner lining fluoroplastics, impeller, the pump cover of lining bag fluoroplastic, mechanical seal cover, mechanical seal, pull bar, the motor of band hollow shaft, base plate, support, the described pump housing is connected by support and motor flange, pump cover is fixed in the pump housing by cooperation, impeller top is with internal screw thread, with a nut, a pull bar is fixed on internal screw thread place, impeller top is coordinated with motor-hollow axle by tapering, and is fixed with a nut by the pull bar through motor-hollow axle.The utility model is not vulnerable to the erosion of conveying liquid body, and not easily produce between impeller shaft and motor and loosen, repair and replacement are convenient, and mechanical seal is good.
Description
Technical field
The utility model relates to pump valve technical field, is specifically related to a kind of Novel fluorine plastic pipe road pump.
Background technique
Pipeline mounted pump mainly applies to chemical industry, petroleum industry strange land is carried, the operating modes such as supercharging, and the utilization of fluoroplastic on pipeline mounted pump solves conveying and the supercharging of strongly corrosion liquid, but common fluoroplastic pipeline pump impeller is directly fixed on motor shaft by bolt, after using a period of time, fixing bolt may be subject to environment (acid mist that particularly chemical industry is common) erosion, impeller is subject to the effect of center of gravity and fluid axial force simultaneously, can produce loosening between impeller shaft and motor, loosen once impeller shaft and motor produce, originally the mechanical seal of sealing will leakage, the liquid pumped will serious environment pollution.
Model utility content
The purpose of this utility model is to provide one and is not easily etched, and repair and replacement are convenient, the Novel fluorine plastic pipe road pump that mechanical seal is good.
In order to solve problem existing in background technique, the utility model is by the following technical solutions: comprise the pump housing of inner lining fluoroplastics, impeller, the pump cover of lining bag fluoroplastic, mechanical seal cover, mechanical seal, pull bar, the motor of band hollow shaft, base plate, support, the described pump housing is connected by support and motor flange, pump cover is fixed in the pump housing by cooperation, impeller top is with internal screw thread, and impeller outer surface of cupular part is coordinated with motor-hollow axle by tapering; Pull bar is through motor-hollow axle, and two ends are all with thread, and wherein the nut in one end is fixed on internal screw thread place, impeller top, and motor-hollow axle and impeller tightly pin by a other end nut.
The utility model is not vulnerable to the erosion of conveying liquid body, and not easily produce between impeller shaft and motor and loosen, repair and replacement are convenient, and mechanical seal is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of Novel fluorine plastic pipe road pump, it comprises the pump housing 2 of inner lining fluoroplastics, impeller 9, the pump cover 3 of lining bag fluoroplastic, mechanical seal cover 4, mechanical seal 8, pull bar 6, with the motor of hollow shaft 7, base plate 1, support 5, the pump housing 2 is connected by support 5 and motor flange, pump cover 3 is fixed in the pump housing 2 by cooperation, impeller 9 top is with internal screw thread, with a nut, a pull bar 6 is fixed on internal screw thread place, impeller 9 top is coordinated with motor-hollow axle 7 by tapering, and is fixed with a nut by the pull bar 6 through motor-hollow axle 7, such impeller 9, motor-hollow axle 7 is just closely combined together, impeller 9 is not axially just having the possibility of play, during work, motor-hollow axle 7 has just synchronously driven impeller 9 to rotate, wherein all lining bag fluoroplastic thickness all >=3mm, impeller 9 is formed by the inserts entirety lining bag fluoroplastic of top tape tapering in addition, impeller inserts welds a flange plate by steel impeller shaft and forms, impeller 2 with comprise motor-hollow axle 7, pump shaft taper fit, and fixed by pull bar 6, impeller 9 and motor-hollow axle 7, pump shaft synchronous axial system,
Also very convenient during maintenance, if need to change impeller 9 or mechanical seal 8, pine removes the nut of motor fan housing one end on pull bar 6, the nut that another rotation set one thickeies, and touching this nut, pull bar 6 will impeller 9 produce loosening with motor-hollow axle 7, with regard to replaceable impeller 9 or mechanical seal 8.
Claims (4)
