Description
Technical field:
The utility model relates to a kind of rotor pump.Be specifically related to a kind of three lobed rotor pumps.Belong to the mechanical attachment technical field.
Background technique:
Three lobed rotor pumps belong to volume type rotor pump, its working principle is that motor passes through retarder, slow down and drive a pair of synchromesh gear on master, the driven axle, synchromesh gear drives two three cam-type rotors again, and when the cam of two rotors wherein during at negative cavity, pump begins imbibition, when running to hyperbaric chamber, begin discharge opeing, rotor rotates continuously, and two chambeies replace suction liquid, reaches the purpose of fed sheet of a media.
Because there is synchromesh gear to drive, can keep certain clearance between two rotors of three lobed rotor pumps, this had both helped the conveying of high viscosity liquid, make the rotor of this pump itself just need not lubricate and to work again, be the ideal product that replaces traditional screw pump, be applicable to sticking, thick or contain medium solid particle, that wearing and tearing are arranged.As: crude oil, mud, pitch, slurry, glue, water coal slurry etc.
Before the utility model was made, three traditional lobed rotor pumps generally were made up of motor, retarder, coupling, driving gear, driven gear, driving shaft, driven shaft, synchronized gear box, the pump housing and three cam-type rotors etc.It mainly has the following disadvantages:
1, pump body device is in synchronized gear box, each two totally four sealings about its driving shaft and driven shaft sealing need to adopt, and can only adopt packing seal, cause sealing reliability poor, the easy seepage of medium in the pump housing and pollute gear and bearing in the synchronized gear box, the wearing and tearing of accelerating gear and bearing reduce its working life.
2, the driven shaft in the synchronized gear box adopts keyway to connect with being connected of driven gear, immobilize by the gap between the blade of two three cam-type rotors of driving and driven gear driven, blade is directly contact wearing and tearing easily when engagement, also can not repair behind the blade wear.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, three lobed rotor pumps that provide the gap between the blade of a kind of sealing reliability height, two three cam-type rotors to finely tune.
The purpose of this utility model is achieved in that a kind of three lobed rotor pumps, comprising: motor 1, retarder, coupling, driving gear, driven gear, driving shaft, driven shaft, synchronized gear box, the pump housing and three cam-type rotors is characterized in that:
Described motor links to each other with retarder, retarder links to each other with coupling, coupling links to each other with driving shaft 6, driving shaft and driven shaft are installed in the synchronized gear box and the pump housing, driving gear and driven gear are installed on respectively on the synchronized gear box interior driving shaft and driven shaft, driving gear and driven gear are meshing with each other
Described three cam-type rotors have two, are installed on respectively on the driving shaft and driven shaft in the pump housing, and rotation cooperatively interacts.
The utility model three lobed rotor pumps, the endoporus of described driven gear is made the taper hole shape, the corresponding site of driven shaft with matching is also made the axis of cone, and on the driven shaft of this axis of cone side, be shaped on adpting flange, along the circumferential direction offer the adjustment hole of oval shape on the driven gear, driven gear is placed on the axis of cone of driven shaft, is connected with adpting flange on the driven shaft by attachment bolt.
The utility model three lobed rotor pumps is characterized in that: device has mechanical seal device on driving shaft between the described synchronized gear box and the pump housing and the driven shaft.
Compare with existing three lobed rotor pumps, the utlity model has following advantage:
1, pump body device is in the synchronized gear box outside, and its driving shaft and driven shaft sealing only need to adopt two seal arrangements to seal, and can adopt mechanical seal, and sealing reliability is good, the component long service life.
2, the driven shaft in the synchronized gear box adopts taper hole to be connected with being connected of driven gear, loosening attachment bolt, rotate driven gear, can finely tune gap between the blade of two three cam-type rotors, thereby make the blade of two three cam-type rotors when engagement, keep certain clearance not contact, to prevent wearing and tearing between the two, improve its working life.And also can finely tune reparation behind the blade wear.Be convenient in manufacture process, solve cam blade gap each other simultaneously.
