Summary of the invention
Goal of the invention of the present utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, take up an area of less and lightweight helical rotor pump.
Goal of the invention of the present utility model is achieved in that a kind of helical rotor pump, comprise pump case, mechanical sealing element, stator, be located at the screw rod in the stator and be located at the pump cover of pump case end, be respectively equipped with medium import and media outlet on pump case and the pump cover, it is characterized in that: a side of relative pump cover is provided with the body that is used to install mechanical seal on the described pump case, and the other end of body is connected with the flange of motor.Connecting bushing is contained on the shaft extension of motor, and passes in the body, and the cylindrical of intrinsic coupling shaft is provided with mechanical sealing element, is provided with connection set between screw rod input end and the coupling shaft.
Described connection set is a universal joint.
Described mechanical sealing element is a double mechanical seal spare.
Between connection set and the screw rod, be straight pin between connection set and the coupling shaft and be connected.
Described connection the tip of the axis has the mounting hole that matches with motor reel, has set screw hole on the sidewall of mounting hole.
Be equipped with rapid pipe joint on described medium import and the media outlet.
Described pump cover is provided with base.
The outside of described connection set is provided with stuffing box gland, and stuffing box gland is a rubber sealing boot.
The utility model improves existing helical rotor pump, a side of pump cover is provided with a body that is used to install mechanical seal relatively on pump case, be provided with coupling shaft in the body, mechanical sealing element then is located between body and the coupling shaft, is provided with connection set between screw rod input end and the coupling shaft.Improve by driving mechanism, omitted parts such as transmission shaft, coupling, bearing bracket stand, make the kinetic force of motor directly act on input end, shortened complete machine structure length effectively, reduced machine volume and weight to screw rod to existing helical rotor pump.Helical rotor pump of the present utility model replaces the transmission shaft of existing helical rotor pump with universal joint, can make the eccentric rotary of carrying out that screw rod continues, and improves the stability of its operation.In addition, between body and coupling shaft, double mechanical seal spare is set, therefore mechanical sealing element need not utilize the medium of being pumped to cool off and lubricate in the course of the work, make mechanical sealing element can the tool that has filled lubricant oil independently, the cleaning chamber in work, guarantee the stability of its operation.
