Description
Technical field
The present invention relates to a kind of pouring magnesium-alloy quantitatively pump, which mainly applies to the fields such as magnesium alloy cast, is
The productions such as Die Casting and gravitational casting provide quantitative accuracy high magnesium alloy fused mass.
Background technology
In magnesium alloy pressure-casting and gravity casting process, apparatus for pouring magnesium-alloy quantitatively is needed to be cast to compression chamber of die casting machine or gravity
Moulding chamber provides the accurate magnesium alloy fused mass of weight.
Currently, more traditional casting device is screw rod constant displacement pump or sliding vane rotary pump, the two is easy by magnesium in use
Solid-state slag inclusion in melt is stuck, results in the need for often clearing up, and the frequency of cleaning reaches must clear up once for every 24 hours, and
Cleaning is got up more difficult.Magnesium alloy centrifugation quantitative pouring pump due to the above reasons, starts by market extensive use, but at present
Magnesium alloy centrifuges quantitative pouring pump, although the stuck frequency substantially reduces, cleaning cycle also lengthens significantly, and presently commercially available magnesium closes
The connection of gold centrifugation constant displacement pump, syringe pump method orchid and pump barrel is all made of metal tube connection, and metal tube lower part is immersed in Serum Magnesium, in magnesium
Near melt liquid level line, the easily slagging of metal tube surfaces externally and internally, and the slag cleaning of inside pipe wall is inconvenient, so as to cause
Pump drive shaft and metal tube between spacing constantly reduce, eventually lead to pump drive shaft it is stuck with metal tube, cause proportioning device quantify
It is inaccurate.Another presently commercially available centrifugal pump starts to occur the tubular type connection structure of syringe pump method orchid lower end being changed to 3 or more metal columns companies
The structure connect, which can preferably reduce holddown phenomenon, but the metal tie rods of this structure are directly fixed with syringe pump method orchid
Connection, causes the height for pumping out the mouth of a river that can not adjust, the using flexible and adaptability of pump substantially reduce, and can only generally meet spy
Fixed magnesium-alloy smelting furnace demand, the interchangeability pumped between the different type of furnaces substantially reduce so that user need for different smelting furnaces it is standby different
Pump spare part, occupation of capital rate is big, management it is more complicated.
Invention content
The deficiency that the present invention is pumped aiming at above-mentioned commercially available pouring magnesium-alloy quantitatively, a kind of cast quantitative accuracy height of exploitation,
Cleaning gap periods are long, cleaning is convenient and cleaning labor intensity is low, pump out the novel magnesium that the mouth of a river is height-adjustable, interchangeability is high closes
Golden quantitative pouring apparatus.
According to above-mentioned mentality of designing, to mitigate the phenomenon that syringe pump method orchid and pump barrel connecting component slagging cause pump shaft stuck, this
End flanges are connect with pump barrel attachment device using 3 connecting rods under the bearing block of quantitative pouring apparatus, increase attachment device with
Gap between pump rod decreases the area of slagging, even and if connecting rod have a small amount of slagging, can also at any time facilitate at the scene
It quickly cleans, it, will not be stuck due to slagging between pump shaft and connecting rod after the connecting rod.
In addition, in order to improve the interchangeability pumped between different magnesium-alloy smelting furnaces, pump number of fitting parts and management difficulty are reduced, will be pumped
Structure is designed to, pumps out the structure that can be adjusted to syringe pump method your beautiful writings distance after water, to realize the function, the feature of this structure design
It is that bearing block is designed to the structure of middle cylinder and two end flanges, and the turn on pump flange hole on syringe pump method orchid, when installation, bearing
Seat cylinder passes through syringe pump method flange aperture, and bearing block upper flange is above syringe pump method orchid, and bearing block lower flange is below syringe pump method orchid, bearing block circle
Cylinder diameter is less than syringe pump method flange aperture, and bearing block cylinder can move up and down in syringe pump method flange aperture, can adjust syringe pump method orchid and pump as needed
The relative distance of water outlet is separately connected in syringe pump method flange aperture upper end and adjusts spacer ferrule with the concentric pump height of syringe pump method flange aperture, should
Spacer ferrule lock when can shrink, and with bearing block cylindrical outer hold tightly, to fixed pump flange with pump out at a distance from the mouth of a river, prevent
Distance changes.
Realizing the specific technical solution of the present invention is：
A kind of pouring magnesium-alloy quantitatively pump, by driving motor（1）, shaft coupling（2）, pump shaft（11）, bearing block（4）, bearing
（3）, connecting rod（5）, pump barrel（6）, impeller of pump（7）, pump bottom cover（8）, pump out the mouth of a river（12）, pump height adjust spacer ferrule（10）、
Pump water inlet mouth（13）, syringe pump method it is blue（9）And syringe pump method flange aperture（14）Deng composition, bearing block（4）It is cylindrical shape knot for upper lower flange, centre
Structure, cylinder are installed on syringe pump method flange aperture（14）In, syringe pump method flange aperture（14）Upper end is provided with pump height and adjusts spacer ferrule（10）, bearing block
（4）Upper flange is for installing driving motor（1）, lower flange and connecting rod（5）Upper end is connected, and bearing is equipped in cylinder（3）, pump
