The pump body of the mud pump is provided with a rotating shaft for driving the mud pump. The utility model is characterized in that the mud pump is directly connected with the matching drive motor in a rigid connection mode. The stator part of the matching drive motor is directly and rigidly connected with the pump body of the mud pump, and the rotor of the matching drive motor and the pump body of the mud pump are rigidly assembly together. The stator part of the matching drive motor comprises a stator and a stator shell, and the stator is installed in the stator shell. Two heads of the stator shell are provided with end covers, and the stator shell is connected with the end covers together by fasteners. Meanwhile, one end cover of the stator shell is fixed on the pump body of the mud pump by one fastener. The rotor of the matching drive motor is directly installed on the projecting shaft of the rotating shaft of the mud pump by a shaft sleeve. The stator of the drive motor is in seam-allowance match with a mounting flange on the pump body.
Description
Technical field
The utility model relates to a kind of oil-well rig slurry pump motor-driven structure, refers in particular to a kind of oil drilling platform being connected and the driving structure pattern with alternating-current variable frequency motor and slurry pump device.Be mainly used in the drive motor of the slurry pump device that is applicable in the oil-well rig operation.
Background technique
Slurry pump is one of device of oil drilling platform indispensability.It act as the pressure that produces by slurry pump and pour into mud in the oil well of drilling, and takes ground out of with the cooling drill bit and with generation earth and rubble in the well-digging process.Slurry pump generally is by mechanical type, as diesel engine, or motor-driven.Wherein motor driving is divided into mainly again that direct current motor drives and two kinds of ac variable frequency speed regulation motoring.At present, the kind of drive of slurry pump is mainly belt pulley transmission or two kinds of kinds of drive of sprocket wheel.Promptly be delivered on the slurry pump live axle, drive the mud piston running by belt or chain driving force with motor.The advantage of these two kinds of kind of drive maximums is for can play decelerating effect, and the slurry pump driving arrangement when particularly mechanical type being driven, can be operated near the higher rotation speed of best performance, and be unlikely to be operated near the low working speed of slurry pump like this.But difficulty exist to be installed, and volume is big, and occupation of land is many, and efficient is not high, and problem such as maintenance is big, therefore necessary this is further improved.
The model utility content
Technical problem to be solved in the utility model is the deficiency at the kind of drive of existing oil-well rig slurry pump device and its drive motor, and the transmission device of a kind of more effective oil-well rig slurry pump device and its drive motor is provided.This device can effectively improve transmission efficiency, has high reliability simultaneously, and is non-maintaining, and advantage such as volume is little.
In order to solve the problems of the technologies described above, the utility model proposes the technology implementation scheme is: the transmission device of a kind of oil-well rig slurry pump device drive motor supporting with it, comprise oil-well rig slurry pump and supporting drive motor, the rotating shaft that drives slurry pump is installed on the pump housing of slurry pump, and its characteristics are: slurry pump is to adopt the mode that is rigidly connected directly to be connected with supporting drive motor.Wherein, the stationary part of the supporting drive motor pump housing direct and slurry pump is rigidly connected, and the pump housing rigid group of the rotor of supporting drive motor and slurry pump is fitted together.The stationary part of described supporting drive motor comprises stator and stator case, stator is installed in the stator case, stator case two is provided with end cap, and stator case links together by fastening piece and end cap, and a head end of stator case lid is fixed on the pump housing of slurry pump by fastening piece simultaneously.The rotor of supporting drive motor then is directly installed on the projecting shaft of slurry pump rotating shaft by the mode of axle sleeve.Coaxality guarantees by the mounting flange seam on the pump housing between the stator of motor and rotor.When electrical power rotated, rotor directly drove the slurry pump operation by axle sleeve, and need not by belt pulley or sprocket driving.
The utlity model has following advantage.The first, the slurry pump drive motor directly drives slurry pump, has saved slurry pump or sprocket driving link, has improved transmission efficiency; The second, owing to saved slurry pump or sprocket driving link, simultaneously because drive motor saves the highest bearing of probability of malfunction, so the reliability of slurry pump device can improve greatly; The 3rd, the slurry pump transmission device is installed more convenient, and is simple; The 4th, slurry pump transmission device maintenance significantly reduces; The 5th, drive motor is directly installed on the projecting shaft of the pump housing of slurry pump and rotating shaft, can significantly reduce the shared place of slurry pump device.
