Description
Technical field
The present invention relates to a kind of pump more particularly to a kind of magnetic drive pumps for being used to convey solids-laden fluid medium.
Background technology
At present, the complete No leakage of magnetic force driving pump is widely used in all kinds of inflammable, explosive, toxic, harmful, valuable etc.
The conveying of liquid medium.Magnetic force driving pump must not contain solid to having high requirement by the degree of purity of conveying liquid medium in medium
Body particle usually installs filter additional on magnetic drive pump intake preceding pipeline, prevents solid particle from entering pump chamber, influences and damages
The normal operation of pump.
It installs 40-60 mesh indigo plant formula filters before pump intake additional under normal circumstances, and has strict demand to filter effective area,
Ensure to pump each performance parameter with this and technical parameter is unaffected, also need to carry out filter in routine work periodically clear
Reason, otherwise particle packing be easy to cause plugged filter, causes pump intake charging insufficient, prevents magnetic force pump depletion from causing chain event
Barrier.
Invention content
The purpose of the present invention is exactly to solve the above-mentioned problems, to provide one kind for conveying solids-laden fluid Jie
The magnetic drive pump of matter.
In order to achieve the above object, present invention employs following technical schemes：It is a kind of to be used to convey the liquid containing solid particle
The magnetic drive pump of body medium, including the pump housing, impeller, pump shaft, pump cover, thrust disc assembly, axle sleeve, shelves set, bearing block, bearing holder (housing, cover), interior
Magnet rotor assembly, separation sleeve, outer magnet rotor assembly and motor, the impeller are equipped with balance hole, the high pressure one of balance hole
Side is equipped with balance hole strainer.
The pump cover is equipped with circulation port, and the high pressure side of circulation port is equipped with circulation port strainer.
The impeller is the half-opened impeller that can convey the liquid medium containing solid particle, suspended matter.
The pump shaft is equipped with half-via and is attached thereto logical side opening, side opening and bearing chamber.
The present invention is had the following advantages that and feature as a result of above technical scheme：
1st, it is simple in structure, it is easily manufactured：Balance hole and circulation port are opened up, and in height in impeller and pump cover by Theoretical Design
Side welding strainer is pressed, prevents solid particulate matter from entering the bearing chamber of pump and interior magnet rotor chamber, while pump has been effectively ensured
Performance parameter is stablized.
2nd, reasonable design：When using whole pump operation by the Liang Ge balance chamber of impeller balance hole and impeller and pump cover composition
Reach axial force balance, by pumping the heat generated when recycle loop cools down pump operation in each section pressure difference composition of volute chamber itself
Amount, the friction pair that half-via cooling and lubricating bearing holder (housing, cover), axle sleeve and thrust disc is set to be formed on axis, entire design is all of pump
Itself fluid behaviour designs.
3rd, securely and reliably, Maintenance free, use scope are wide：The design solid particulate matter will not block strainer, eliminate biography
It unites and installs the work of filter periodic cleaning maintenance additional in pump intake, avoid the hair of the magnetic force failure of pump caused by plugged filter
It is raw；And some process conditions need to allow particle that can be widely used in magnetic drive pump by, the design to contain in actual condition
There is the field of solid particle.
Description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Specific embodiment
Referring to Fig. 1, the magnetic drive pump for being used to convey solids-laden fluid medium of the invention, for conveying containing solid
The magnetic drive pump of the liquid medium of grain, including the pump housing 1, impeller 2, pump shaft 3, pump cover 4, thrust disc assembly 5, axle sleeve 6, shelves set 7, bearing
Seat 8, bearing holder (housing, cover) 9, interior magnet rotor assembly 10, separation sleeve 11, outer magnet rotor assembly 12 and motor 13 are equipped with flat on impeller 2
Weighing apparatus hole 21, the high pressure side of balance hole are equipped with balance hole strainer 22.
Circulation port 41 is equipped on pump cover 4, the high pressure side of circulation port is equipped with circulation port strainer 42.
Half-via is equipped on pump shaft and is attached thereto logical side opening, side opening and bearing chamber.
Impeller in the present invention is the half-opened impeller that can convey the liquid medium containing solid particle, suspended matter.
Magnetic drive pump of the present invention sets balance by setting balance hole 21 on half-opened impeller 2, in the high pressure side of balance hole 21
Hole strainer 22 can effectively prevent solid particle from entering the bearing chamber of magnetic drive pump；By setting circulation port in the outer of pump cover 4
41, the side setting circulation port strainer 42 of circulation port 41 can effectively prevent particle to enter the interior magnet rotor chamber of magnetic drive pump, twice filter
Net, which is effectively ensured, to be stayed in by the solid particle contained in conveying liquid medium in pump chamber, without entering the bearing bore of magnetic drive pump and interior
Magnet rotor chamber.
Present invention employs half-opened impellers 2, can convey the liquid medium containing suspended matters such as solid particle, fibers；Half
2 back side of unshrouded impeller is equipped with balance hole 21, and set balance hole strainer, the balance hole 21 in its high pressure side by Theoretical Design
Design ensure magnetic drive pump start run in balance chamber's A and B synergy for being formed with impeller and pump cover reach axial force
Purpose is balanced, while the pressure at counter balance pocket A is more than the pressure of impeller inlet chamber, so as to prevent solid particle from becoming silted up in balance hole
Product blocks balance hole；Pump cover 4 is asymmetric according to each cross-section pressure of volute chamber, devises circulation port 41, magnetic drive pump is made to produce in operation
Raw heat whole band exists, and pumps and recycled in normal work close to volute chamber side setting circulation port strainer 42 in circulation port 41
Hole strainer 42 is washed away by liquid medium in volute chamber, blocking of depositing here so as to avoid solid particle, realizes magnetic drive pump
Convey the liquid medium containing solid particle.
