Abstract
The utility model discloses a spiral casting pump which comprises a bearing support assembly, an upper connection plate and a lower connection plate. A connection plate middle pipe is arranged between the upper connection plate and the lower connection plate, a motor shaft is arranged in the center of the bearing support assembly, a pump cylinder is arranged at the bottom of the lower connection plate, and a pump nozzle is arranged on the lateral side of the pump cylinder. The spiral casting pump is characterized in that a long shaft is arranged in the center of the pump cylinder, the long shaft is fixedly connected with the motor shaft through a coupler, a spiral cylinder is arranged at the lower portion of the pump cylinder, a spiral rod fixedly connected with the long shaft is arranged in the center of the spiral cylinder, and a graphite pad is arranged at the top of the spiral cylinder between the spiral cylinder and the spiral rod. The spiral casting pump has the advantages that the spiral casting pump combines advantages of a plunger pump and a centrifugal pump, flow hardly changes on different pressure conditions, flow is even, the spiral casing pump is in the modular design, and parts are strong in generality and convenient to dismount. The spiral casting pump is structurally characterized in that only a rotor serves as a moving part so as to save power and be short and simple in runner, large in open area and small in oil flow perturbation.
Description
Technical field
The utility model belongs to the pump field, particularly a kind of spiral casting pump.
Background technique
In the smelting process of magnesium metal or magnesium alloy, heat through smelting furnace from the raw material of solid, obtain magnesium metal or the magnesium alloy liquid pressure of molten state, and then be transferred to holding furnace, be transferred to again the casting machine casting.Although the medium that shifts is liquid, what change over to is the metal liquid of melting, has the characteristics of the high heat of high temperature.In the process of casting, need to have the casting pump of particular design could adapt to this technological requirement.
Generally all adopt in the market plunger pump to follow centrifugal pump, these two kinds of pumps are extremely inhomogeneous in the control of different pressures down-off.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of spiral casting pump.
To achieve these goals, the technical scheme in the invention for solving the technical problem is:
A kind of spiral casting pump comprises bearing support assembly, upper junction plate, lower connecting plate, is provided with in the connecting plate between upper junction plate and the lower connecting plate and manages, and bearing support assembly center is provided with motor shaft; Pump barrel is located at the lower connecting plate bottom; The pump barrel side is provided with the pump mouth; It is characterized in that, the pump barrel center is provided with major axis, and major axis is fixedly connected with motor shaft by coupling, and described pump barrel bottom is provided with spiral-tube, the spiral-tube center is provided with the screw rod affixed with major axis, and described spiral-tube top is provided with graphite pads between spiral-tube and screw rod.
The beneficial effects of the utility model: spiral casting pump combines the advantage of plunger pump and centrifugal pump, and is namely very little in different pressure condition down-off changes, and flow is very even, modular design, and component universality is strong, convenient disassembly; The characteristics of structure aspects: only have movement parts of rotor more to save electricity, runner weak point and simple, area of passage is large, and oily flow disturbance is little;
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of spiral casting pump as shown in Figure 1 comprises bearing support assembly 1, upper junction plate 2, lower connecting plate 3, is provided with between upper junction plate 2 and the lower connecting plate 3 and manages 4 in the connecting plate, and bearing support assembly 1 center is provided with motor shaft 5; Pump barrel 6 is located at lower connecting plate 3 bottoms; Pump barrel 6 sides are provided with pump mouth 7; Pump barrel 6 centers are provided with major axis 8, major axis 8 is fixedly connected with motor shaft 5 by coupling 9, described pump barrel 6 bottoms are provided with spiral-tube 10, and spiral-tube 10 centers are provided with the screw rod 11 affixed with major axis 8, and described spiral-tube 10 tops are provided with graphite pads 12 between spiral-tube 10 and screw rod 11.
Spiral casting pump combines the advantage of plunger pump and centrifugal pump, and is namely very little in different pressure condition down-off changes, and flow is very even, modular design, and component universality is strong, convenient disassembly; The characteristics of structure aspects: only have movement parts of rotor more to save electricity, runner weak point and simple, area of passage is large, and oily flow disturbance is little;
Above-mentioned is the utility model preferred forms, and those skilled in the art's simple change and replacement all are within the protection domain of the present utility model in related domain.
