Abstract
The utility model discloses a lead pump device and the craft which is capable of quickly lift the lead and other alloy liquid, and suits to the deep cauldron body with high tonnage, casting with full automation and operating reliably. The utility model comprises an electric control, an electric machine, a transmission shaft, a stander, a pump barrel, impellers, a lead pump pipe and a slipknot head of the lead pump pipe, two connecting flanges are arranged in the output end of the transmission shaft, the flange output which is close to the pump is welded with the impellers which arte made of the cylinder round steel, cuboids laminas are directly and equably welded in the sections of the impellers, the centre of the impeller has a shaft hole, the operation of the electric machine is controlled by the electric control device.
Description
Affiliated technical field
The utility model relates to a kind of vane pump device, and the lead that is applicable to the automation casting of particularly a kind of energy fast lifting lead and alloy liquid thereof is smelted special use and taken out plumbous pump installation.
Background technology
The existing plumbous dedicated pump device of smelting; be lead and alloy liquid thereof slowly to be delivered in the lead pig mould by the worm screw rotation; the speed of worm screw rotation is generally all slower; along with the increasing of smelting the pot tonnage; the degree of depth of pot is deepened greatly; the length of worm screw also extends thereupon; this has just increased the distortion probability of worm screw in the plumbous liquid of high temperature; worm screw and circular tube external wall friction; make the job insecurity of pump; plumbous liquid very easily produces the problem that plumbous liquid freezes defeated lead pipe off and on, and this situation often occurs in the winter time especially; it firmly is a trouble that defeated lead pipe freezes; dismounting dress often just needs 1-2 hour, and a little longer generation that also can cause the similar problem of later process of time is frozen as the casting machine lead outlet etc.; special in the production process of metalization; often grow downtime one, microalloy just produces oxidation in the smelting pot; scaling loss; segregation causes the defective of product.Because the plumbous pump speed of worm screw is slow, so be not suitable for the demand of high speed casting machine automated production.
Summary of the invention
Task of the present utility model be design a kind of can fast lifting lead and the suitable large-tonnage pot body of alloy liquid, full-automatic casting, reliable operation take out plumbous pump installation.It is easy to use also to have maintenance.Make simple economy, the characteristics that fault rate is low.
The utility model includes: electrical control, motor, power transmission shaft, frame, pump case, impeller, defeated lead pipe and defeated lead pipe slipknot, at the power transmission shaft output two adpting flanges are arranged, flange shaft and impeller welding near the pump housing, last pump case is fixed with two bolts and support, following pump case is taken tooth with four bolts and last pump case and is fixed on the pump case, impeller is to use cylindrical round steel, directly welds the blade of cuboid equably and make on its cross section circle, and shaft hole is left in the impeller center of circle.The running of motor is controlled by electrical control gear.
The utility model has following effect: take out plumbous pump owing to adopted the lead of automation casting to smelt, can be with plumbous liquid vertical-lift, respond the given casting signal of full-automatic casting machine fast, and avoid freezing the generation of plumbous problem.Because axle and impeller use electric welding directly to weld; so functional reliability is good; under the prerequisite of considering functional reliability, consider economy easy to maintenance and maintenance; increased a flange short as far as possible with pump housing distance; convenient regularly transposing impeller and impeller shaft coupling, seldom bad pump case can be utilized simultaneously.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plumbous vane pump impeller schematic cross-section of smelting.
Among the figure: 1 motor, 2 shaft joints, 3 shafts, 4 frames, 5 flanges, 6 pump housings, 7 impellers, 8 advance plumbous mouth, 9 adpting flanges, 10 go out lead pipe slipknot, 11 defeated lead pipes, 12 electrical equipment control, 13 electronic probes, 14 casting machines, 15 gripper shoes.
The specific embodiment
Describe embodiment in detail below in conjunction with accompanying drawing.The utility model is to take out the worm screw that plumbous impeller of pump has substituted original plumbous pump, solved the quick vertical-lift problem of the plumbous liquid of large-tonnage pot body, the impeller at the higher position of fault rate in the pump directly is welded on the minor axis, has solved and taken out plumbous problem off and on, both solved and frozen plumbous problem.The special-purpose course of work of taking out plumbous pump of plumbous smelting: motor 1 is according to given rotary speed instruction rotation during startup, Motor Shaft drives impeller 7 rotations that shaft 3 makes plumbous pump by shaft joint 2, plumbous liquid enters plumbous pump by advancing plumbous mouthful 8, the impeller 6 that is rotated extrudes and enters lead outlet, enters casting machine by lead outlet flange 9, lead outlet slipknot 10 from defeated lead pipe 11.The signal of telecommunication of electronic probe 13 is received in electrical control 12 when the plumbous liquid of casting machine tundish has been expired, at this moment, motor reduces rotating speed and is in the standby running, this rotary speed can just be promoted to out plumbous liquid level plumbous slipknot 10 above A places (seeing Fig. 1 for details) and fluctuate in the pipe herein, characteristic with metal heat-conducting heats defeated lead pipe, simultaneously when the plumbous liquid of casting machine tundish drops to the stock set point, electrical control will be received the stock signal of telecommunication of electronic probe 13 again, tap tundish that son enter casting machine at plumbous liquid of the very first time that motor speed the is accelerated defeated lead pipe A that gushes out very soon this moment, and a spot of in this moment defeated lead pipe frozen plumbously can be fallen by molten brush in the plumbous liquid that crashes down.Solved and frozen plumbous problem in the defeated lead pipe.Electrical control is selected frequency modulator for use to the rotating speed control of alternating current generator, and it is given by the speed potentiometer on the control panel to take out plumbous given speed, and the standby rotating speed of plumbous pump is set on frequency converter by the actual tests situation again.
Claims (3)
1, a kind of plumbous smelting taken out plumbous pump installation, comprises taking out plumbous pump, frame, defeated lead pipe, it is characterized in that: be provided with motor above taking out plumbous pump, by the shaft and the impeller fixed connection of taking out plumbous pump of driven by motor.
2, the plumbous smelting according to claim 1 taken out plumbous pump installation, it is characterized in that described shaft output top is provided with two adpting flanges, near the shaft and the impeller welding of the flange of taking out plumbous pump, take out plumbous pump upper shell and frame fixed connection, take out the lower house and the upper shell fixed connection of plumbous pump.
3, the plumbous smelting according to claim 1 and 2 taken out plumbous pump installation, it is characterized in that described impeller is tubular round steel, is provided with rectangular blade equably on the circle of the cross section of impeller, and the impeller center of circle is provided with shaft hole.
