Abstract
The utility model discloses a high-abrasion-resistance stator of a screw pump. The high-abrasion-resistance stator comprises a stator shell and a rigid structure, wherein the inner wall of the rigid structure has a helical curved surface structure which is linearly meshed with a rotor; a tungsten alloy layer is arranged on the inner wall of the rigid structure and a rubber layer is arranged on the inner wall of the tungsten alloy layer. The tungsten alloy layer and the rubber layer are arranged on the inner surface of the stator of the screw pump. Compared with the prior art, the high-abrasion-resistance stator has the advantages that 1, the service life of a screw motor is prolonged, and the abrasion resistance of a motor stator is greatly improved; 2, the working stability of the motor is improved, and the rubber layer and the tungsten alloy layer are uniform in thickness, so that during working, the motor is uniformly expanded and can be favorably matched with the rotor; and 3, the amount of site accidents is small, mechanical loss is low, and the drilling cost can be reduced.
Description
Technical field
The utility model relates to a kind of screw pump stator, is specifically related to a kind of screw pump high wearable stator.
Background technique
Helicoid hydraulic motor is one of critical component widely used on the present drilling equipment.Screw pump motor stator internal surface commonly used is only established one deck rubber.Owing in drilling process, often can run into the salinity height, the complex environments such as carbonated and hydrogen sulfide, and rubber under complex environment corrosion-resistant, scratch-resistant performance is poor, has a strong impact on the working life of screw drilling tool motor.
The model utility content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of screw pump high wearable stator is provided.
Its technological scheme is: comprise stator case and rigid construction, the inwall of rigid construction is the spiral camber structure that is meshed with the rotor line style.Inwall at rigid construction is provided with one deck tungsten alloy layer, and the inwall of tungsten alloy layer is provided with one deck rubber layer.
Wherein, described tungsten alloy layer is ferronickel tungsten alloy coating or ni-w-p alloy coating, and its thickness is 0.3-1.5mm.The thickness of described rubber layer is 0.3-2.5mm.
The utility model screw pump stator internal surface arranges one deck tungsten alloy layer and one deck rubber layer, makes it compared with prior art, has following advantage: 1, improved the operating life of screw motor, greatly improved the wear-resisting property of motor stator; 2, improve the working stability of motor, because the even thickness of rubber layer and tungsten alloy layer expands evenly during motor operations, be more convenient for mating rotor; 3, field accident is few, and mechanical loss is little, can reduce drilling cost.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model structural representation.
