__ Hello, Uniform Wall Thickness Stator for Multi Lobe Power Section in Downhole Drilling Motors (Mud Motors) Stators and rotors for the mineral oil transportation (Artificial Lift) In the last years progressing cavity pumps for the mineral oil transportation developed into a superior alternative with regard to conventional “horse head pumps”. Here minimum space, advantages in costs when the pumps are purchased and when they are at work are required, as well as high operational reliability. The demands on the elastomer are very high when crude oil is transported. High pressures, high temperatures, the chemical load of the rubber produced by the concentration of the fluorocarbon hydride of the oil mud and the content of stones and sand represent a challenge for each pump. Here our even wall thickness stator offers vast advantages. The effects of the increase in volume due to the temperature and of the swelling due to the absorption of aromatic compounds are very reduced by the smaller and uniform wall thickness of the rubber. Therefore the function of stator and rotor remains constant over a large operating range. The improved service life offers high operational safety and huge cost savings as non-productive times and setup times are very expensive, mainly in the mineral oil industry. The application of even wall thickness stators allows a shorter structural shape; this is the same with the very expensive rotor. By the use of even wall hollow rotors supplementary costs can be saved because of the material saving and the ingenious production process. With six-lobe even wall thickness stators the efficiency is clearly improved by the constant rubber wall thickness and the rigid geometry. The drilling capacity is nearly doubled in comparison with conventional motors of the same size. -- Subscription Reminder: You're Subscribed to, EvenWall Using the address: druid@druid.dk From: evenwall@hawne.com Wuhan EvenWall Machinery Co.,Ltd.
