Abstract
The invention discloses a liquid delivery pump for wells, which comprises a special cylindrical motor (1) with a submersible structure, a pump body (2), a sealing device, an impeller (3) and an outlet pipe (4), wherein the impeller (3) has an upper open structure; the pump body (2) adopts a radial suction inter-shaft output structure; and surfaces of overflowing parts of the pump body (2) and the impeller (3) are provided with rubber wear-resistant layers (5). By adopting the structure, the overflowing part of the pump has the advantages of corrosion and wear resistance, good mechanical sealing property, and safety and reliability, so the service life of the pump is prolonged.
Description
Technical field
The present invention relates to a kind of pump structure, especially relate to a kind of liquid delivery pump for wells.
Background technique
Liquid delivery pump for wells is the pull the plug water lift facility of work of motor and water pump direct connection, it is applicable to from deep-well extracts underground water, also can be used for water lift engineerings such as river, reservoir, water channel, be mainly used in people and animals' water in field irrigation and mountain area, plateau, also can use for city, factory, railway, mine, building site water supply and sewage.But for the conveying of halogen medium, muddy water mixed medium, just the anticorrosion antiwear performance to pump has had higher requirement.The seal arrangement of existing liquid delivery pump for wells mostly adopts the back blades structure, the back blades structure produces the pressure opposite with the main impeller direction, to reduce the pressure of sealing part, alleviate the burden of mechanical seal, to prolong the working life of pump, but this seal arrangement is still safe and reliable inadequately, causes taking place leakage phenomenon, thereby influences the working life of pump.
Summary of the invention
The purpose of this invention is to provide a kind of anticorrosion antiwear, the good liquid delivery pump for wells of mechanical sealing performance.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises special-purpose diving structure cylinder type motor, the pump housing, seal arrangement, impeller and drain pipe, impeller is put open architecture on being, the described pump housing adopts and radially sucks the between centers export structure, and the flow passage site surface of the pump housing and impeller is provided with the rubber wear-resisting layer.
Seal arrangement of the present invention adopts the double sealing structure of back blades and unit loading type double seals.
External wash tub pipe on the pump housing of the present invention, wash tub pipe pass to the impeller top.
Cylinder type motor of the present invention is provided with built-in closed cycle water-cooling apparatus, external turnover water-cooling tube on the motor.
The said structure that the present invention adopts can make overcurrent position anticorrosion antiwear, the mechanical sealing performance of pump good, safe and reliable, thereby prolong the working life of pump.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as structural representation of the present invention
Embodiment
By accompanying drawing as can be known, this liquid delivery pump for wells comprises special-purpose diving structure cylinder type motor 1, the pump housing 2, seal arrangement, impeller 3 and drain pipe 4, and impeller 3 is put open architecture on being, the described pump housing 2 adopts and radially sucks the between centers export structure, this structure hydraulic loss is little, the operational efficiency height.The flow passage site surface of the pump housing 2 and impeller 3 is provided with rubber wear-resisting layer 5.The pump housing and impeller adopt two material castings and hot melting process processing, have good anticorrosion, wear-resisting, the brilliant function of resistive connection, especially impeller design is put open type on being does not have blockage structure, the not only wear-resisting resistive connection crystalline substance of the rubber wear-resisting layer of front side of vane, and plasticity is good, can effectively particulate matter and crystal be peeled off the back discharge pump housing fast automatically by the active force of the trickle distortion generation of front side of vane, and can prevent the formation of secondary crystallization thing.Seal arrangement of the present invention adopts the double sealing structure of back blades 6 and unit loading type double seals 7, and is safe and reliable, do not have to leak.Be more than the twice of common submersible motor sealing the working life of this double sealing structure.External wash tub pipe 8 on the pump housing 2 of the present invention, wash tub pipe 8 passes to impeller 3 tops, in time liquid impurity is washed, and prevents the obstruction of impeller place.Cylinder type motor 1 of the present invention is provided with built-in closed cycle water-cooling apparatus, external turnover water-cooling tube 9,10 on the motor 1.Electric motor starting and operation design can be disposed frequency-changing control system, frequency-changing control system can according to actual conditions and requirement increase and decrease the medium transport amount automatically and when starting because of the harm of overcurrent to motor, fully reach energy-conservation, efficient.
Claims (4)
1. liquid delivery pump for wells, comprise special-purpose diving structure cylinder type motor, the pump housing, seal arrangement, impeller and drain pipe, impeller is put open architecture on being, it is characterized in that described pump housing employing radially sucks the between centers export structure, the flow passage site surface of the pump housing and impeller is provided with the rubber wear-resisting layer.
2. a kind of liquid delivery pump for wells according to claim 1 is characterized in that described seal arrangement adopts the double sealing structure of back blades and unit loading type double seals.
3. a kind of liquid delivery pump for wells according to claim 1 is characterized in that external wash tub pipe on the described pump housing, and wash tub pipe passes to the impeller top.
