Description
Technical field
The utility model belongs to pump technology field, is related to a kind of centrifugal pump, more particularly to a kind of horizontal pipeline centrifugal pump.
Background technology
Centrifugal pump is to be rotated using impeller and make liquid that centrifugal motion occur come work, and centrifugal pump operationally, is relied on
The impeller of rotation at a high speed, liquid obtains energy to improve pressure in the presence of centrifugal inertial force, centrifugal pump before work, pump
Internal and water inlet must hydraulically full medium.
Horizontal pipeline centrifugal pump is commonly used in industry and the cold-warm water such as urban water supply and sewerage is circularly-supercharged and coordinative composition of equipments, passes
The horizontal pipeline centrifugal pump of system is typically only applicable to conveying clear water and physicochemical properties are used similar to other liquid of clear water,
And when the liquid medium of conveying is volatile or the occasion of crystallization, contained molecule is easy to damage in the pump housing in its medium
Mechanical seal, causes centrifugal pump seal hydraulic performance decline, and due to being fastened by nut between all parts of centrifugal pump
Sealing, regular maintenance cleaning inconvenience.
The content of the invention
The purpose of this utility model is directed to the above-mentioned problems in the prior art, there is provided a kind of practicality more preferably and
The horizontal pipeline centrifugal pump of convenient cleaning.
The purpose of this utility model can be realized by following technical proposal：A kind of horizontal pipeline centrifugal pump, including base
With the pump head, motor being arranged on base, spiral case is provided with described pump head, the power transmission shaft of the motor passes through pump head and stretches
Enter in spiral case, impeller is provided with by flat key on described power transmission shaft, be connected on described spiral case and axially arranged entered
The mouth of a river and the delivery port being radially arranged, are provided with conjuncted seat, it is characterised in that be located on described power transmission shaft in described pump head
Mechanical seal and packing seal are respectively arranged with conjuncted seat, are inclined between described pump head and conjuncted seat and is equipped with flush pipe,
Described flush pipe is fixed by setting location nut on conjuncted seat outer wall, and described pump head bottom offers discharge outlet.
The technique effect of this horizontal pipeline centrifugal pump is：When the liquid medium that centrifugal pump is conveyed is volatile or crystallizes,
In its sealing structure（Mechanical seal and packing seal）Place is readily formed solid particle, or after centrifugal pump long-play
Solid particle in liquid medium can be piled up at sealing structure, have impact on the sealing effectiveness of centrifugal pump, and this centrifugal pump is in pump head
Flush pipe is set between conjuncted seat, when centrifugal pump carries out regular maintenance to be cleaned, by injecting cleaning fluid from flush pipe, can
The effective solid particle by accumulation dissolves or rinses out, then external by pump head bottom discharge mouthful excavationg pump, so as to extend
The service life of sealing structure, the porch of flush pipe and discharge outlet can be by valve bonnet seal usually.
The impeller of this horizontal pipeline centrifugal pump is directly mounted on the power transmission shaft of motor by flat key, is led to relative to traditional
Shaft coupling connection is crossed, this mounting structure axial dimension is short, compact conformation, effectively can operate the radial direction and axle for producing by ballast pump
To load, so as to ensure that operating steadily for pump, small, noise is vibrated low.
In a kind of above-mentioned horizontal pipeline centrifugal pump, described water inlet is provided with water injection valve.Can by water injection valve
Toward water filling in the pump housing during playing a part of exhaust and pump startup be centrifuged.
In a kind of above-mentioned horizontal pipeline centrifugal pump, the power transmission shaft afterbody of the motor is coaxially connected with radiator fan,
The protective cover of protection radiator fan has been provided with described motor.
In a kind of above-mentioned horizontal pipeline centrifugal pump, described motor outside is provided with terminal box.
Compared with prior art, this horizontal pipeline centrifugal pump has it by setting flush pipe between pump head and conjuncted seat
Have the advantages that practicality more preferably and is conveniently cleaned.
