Abstract
A vertical chemical pump with a fluoroplastic lining for pipelines comprises a pump body, a pump body lining, a pump cover, a pump cover lining, an impeller, an electric pump shaft, a shaft seal, a motor and a connecting frame, wherein the connecting frame is installed on the pump body, the motor is installed on the connecting frame, and the pump body lining, the pump cover lining and the impeller are integrally formed structural parts made of F46 materials. According to the pump, the vertical installation design is adopted, an outlet and an inlet of the pump are in the same line and provided with the same nominal diameter, the pump and the motor are coaxial, external mechanical seal is selected for the shaft seal, ceramic-graphite polytetrafluoroethene is selected for static and moving rings, and a sealing element is made of superior F46; a high-grade carbon steel part serving as the lining is arranged in the impeller; parts in the pump are high in hardness, abrasion resistance and corrosion resistance; and the pump can be installed at any position of a pipeline directly by a user like a valve and is used for transporting chemical liquid with high purity and corrosion, the motor can be used outdoors when provided with an rainproof cover, and the civil engineering investment of users on the spot can be reduced.
Description
Technical field
The utility model relates to a kind of driven pump, particularly a kind of vertical lining fluorine pipeline chemical pump.
Background technique
Because the pump housing water inlet flow channel of vertical installation is more complicated all, casting or injection moulding or compression molding are all relatively more difficult, so the pump of general chemical industry all is horizontal, the suction chamber of pump is cylinder or cone shape like this, and the manufacturing process of the pump housing has just become relatively letter.Like this, the user of a lot of chemical industries has to select horizontal chemical pump when choosing water pump, so the user has to change pipeline, and the installing space area of horizontal pump is all much bigger than vertical pump, thereby has increased user's capital investment.
Because the factors such as fluoroplastic poor fluidity, difficult forming cause production fluoroplastic chemical pump very difficult.The flow channel shape of the common lining fluorine chemical pump pump housing is complicated on the market now, therefore this lining fluorine molding die is complicated, the mold runner slide block is a lot, runner location inconvenience when causing mold pressing, difficult forming, manufacturing efficiency are low, more easily cause the thin inequality of fluoroplastics lining bed thickness at pump housing runner position, the corrosion of easily breaking.
The endoporus of existing lining fluorine chemical pump impeller liner steel part is a conical bore, and half-finished check is relatively more difficult after the processing of part and the processing.
And vertical lining fluorine pipeline chemical pump specification common on the market is few, and part generalization degree is not high.
The model utility content
The purpose of this utility model is to provide a kind of vertical lining fluorine pipeline chemical pump that adapts to the severe corrosive operating mode.
The purpose of this utility model is achieved in that a kind of vertical lining fluorine pipeline chemical pump, comprise the pump housing and pump housing liner, pump cover and pump cover liner, impeller, electric pump spindle, shaft seal and motor, also comprise link press span, this link press span is installed on the pump housing, and motor is installed on the link press span; Described pump housing liner, pump cover liner and impeller all are integral forming structure spares of F46 material.
Described vertical lining fluorine pipeline chemical pump adopts vertical mounting design, and motor is upper, and the pump housing is lower, and the inlet/outlet of the pump housing is on the same horizontal line, and the nominal bore of pump housing inlet/outlet is identical.
Be provided with carbon steel liner in the described impeller.
Described shaft seal is exterior mechanical seal.
The utility model has following advantage and disadvantage owing to having adopted above technological scheme:
1, pump housing liner, pump cover liner, impeller all adopt pure F46 material one-step mould to form; Free from admixture is separated out, and is very suitable for the chemical liquid of delivery of high purity, highly corrosive;
2, pump adopts horizontal mounting design, axially sucks, and vertical diameter is to spuing, and the pump housing is provided with the installation footing;
3, be provided with a plate between motor and the pump housing, the universal component degree is high, and interchangeability is strong;
4, there is the quality carbon steel part to make lining in the impeller, whole impeller good rigidity, centering is convenient;
5, shaft seal is selected exterior mechanical seal, dynamic and static ring Ceramics-graphite tetrafluoro, and Sealing adopts the F46 of high-quality;
6, pump and electric-motor pump and motor coaxle, impeller directly is contained on the extension shaft of motor, and concentricity is high, and a people just can carry out internal overhaul and part exchanging, and does not need to dismantle pipeline, and whole pump assembly and disassembly are convenient.
