Abstract
The utility model discloses a no-seal automatic control self-sucking pump, which comprises a motor (1), a pump body (2), an impeller (3) and a pump shaft (4) in a split structure. Two sections of the pump shaft are connected by a motor coupler (5) positioned by adopting a concave-convex spigot, and a rigid shaft is composed of fastening bolts in a fixed manner. By adopting the structure, the no-seal automatic control self-sucking pump can improve the processing precision of the pump shaft, ensure original stability of spindle parts, facilitate maintenance and facilitate disassembling and replacing the pump shaft, thereby reducing maintenance cost and improving work efficiency.
Description
Technical field
The utility model relates to a kind of pump structure, especially relates to a kind of nothing sealing automatic control self-priming pump.
Background technique
Not having sealing automatic control self-priming pump and be widely used in industries such as oil, electronics, electric power, chemical industry, metallurgy, medicine, plating, environmental protection, fire-fighting, municipal administration, water purification, defence and military, petroleum industry, digging ore dressing, civil building, is to substitute optimal equipment such as long shaft submerged pump, submersible pump, submerged pump.At present, the main shaft that does not have sealing automatic control self-priming pump adopts integral shaft mostly, and promptly main shaft directly connects with motor shaft, though easy to assembly like this, make troubles for the maintain and replace main shaft.Owing to be subjected to the long structural limitations of length of axle, main shaft is unloaded down from motor shaft at every turn, all main shaft to be slit into two sections, part on the motor shaft could be unloaded down with general utility tool, be changed new axle, each maintenance all wants like this, waste manpower, material, reduced working efficiency.
Summary of the invention
The purpose of this utility model provides a kind of sealing automatic control self-priming pump that the pump shaft dismounting and change become do not have easily.
The problem of the required solution of the utility model realizes by the following technical solutions: it comprises motor, the pump housing, impeller and pump shaft, it is characterized in that described pump shaft is a split-type structural, two sections pump shafts are connected by motor coupler, motor coupler adopts concavo-convex seam location, fixedly forms stiff shaft by clamping bolt.
The said structure that the utility model adopts can improve the machining accuracy of pump shaft, guarantees the original stability of spindle unit, mainly is convenient to maintenance, and the pump shaft dismounting and change is convenient, has reduced maintenance cost like this, has improved working efficiency.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing is depicted as structural representation of the present utility model
Wherein 1, motor 2, the pump housing 3, impeller 4, pump shaft 5, motor coupler
Embodiment
By accompanying drawing as can be known, this nothing sealing automatic control self-priming pump comprises motor 1, the pump housing 2, impeller 3 and pump shaft 4, and described pump shaft 4 is a split-type structural, and two sections pump shafts are connected by motor coupler 5, motor coupler 5 adopts concavo-convex seam location, fixedly forms stiff shaft by clamping bolt.Motor coupler of the present utility model also can adopt the rigid coupling of other structure types that two sections pump shafts are linked up, all should be within protection domain of the present utility model.
Claims (1)
1. one kind is not had sealing automatic control self-priming pump, comprise motor, the pump housing, impeller and pump shaft, it is characterized in that described pump shaft is a split-type structural, two sections pump shafts are connected by motor coupler, motor coupler adopts concavo-convex seam location, fixedly forms stiff shaft by clamping bolt.
