Shale Screen Structure Composition

In general, the shale screen structure has four major components, namely vibrators, sieve box, support or suspension device, transmission.

Vibrating screen has uniaxial and biaxial, their vibrator will be different types due to eccentric re-allocation of different ways, which the block eccentric type is preferred. Screen box is usually composed of three parts, namely, side panels and beams composed of screen frame, screen surface and the clamping device. The rigidity of the vibrating screen frame needs to be adequately safeguarded. Vibrating screen supporting device is critical, vibrating screen support device is inseparable from the elastic elements, such as coil springs, plate springs and rubber springs and so on. Vibrating screen transmission device will be used to drive the coupling and the V-belt. The biggest advantage of the coupling is more stable than the V-belt, working hours is longer, it is not easy to adjust the number of revolutions.

High-efficiency Non-magnetic Drill Collars

As the rapid economic development, non-magnetic drill collars also promote the development of oil and petrochemical products, with the growing demand for oil, further stimulate the development of the oil industry, which shows that non-magnetic drill collars are becoming increasingly important.

Since the non-magnetic drill collars are so important, we should have a better understanding of the equipment. Therefore, not only the details of non-magnetic drill collars to be precise, but also non-magnetic drill collars and other magnetic measuring instruments require accurate results. When selecting the non-magnetic drill collar, we must pay attention to its length, the length of the non-magnetic drill collars should be selected according to the inclination angle and the azimuth angle of the well. For example, when the angle of the well is large, the length of the non-magnetic drill collar should be lengthened. In addition, we also produce slick drill collar and spiral drill collar, for more details, please feel free to call for advice.

Attention Requirement of Screw Conveyor

Different manufacturers of machinery and equipment will produce different qualities of screw conveyor, so when we buy equipment, we must pay attention to these details.

First of all, we should understand the screw conveyor machine work performance characteristics, so that the purchase will have some help, when we face of uneven quality of production of the manufacturer, we have to choose the experience of many years of production of the old manufacturers, but also go to the site to study the actual working environment. Aeration machine manufacturers remind you, in order to allow the screw conveyor to work better, not only select the regular manufacturer, but also have to do a good job maintenance work, which for the normal use of the machine also has some benefits.

DeRun Energy Co., Ltd receives three days training session given by Schlumberger

Nov. 13- Nov. 15 2016, all the staff of DeRun Energy Co., Ltd receives three days training session by Schlumberger. This training session is a part of cooperation program between DeRun Energy and Schlumberger.

Since 2015, DeRun Energy and Schlumberger are starting to develop joint product – downhole motor which adopt Schlumberger Dyna-Drill Stator, the rest part is manufactured by DeRun. This joint develop downhole motor is able to provide extraordinary performance as good as Schlumberger, in low cost. After a long time investment and preparation, the joint motor is put into production and start to serve the customer in oil & gas industry.

This time, to show the solid support form Schlumberger to DeRun Energy, Schlumberger is sending two experienced lecturers from downhole tools division, gives DeRun staff a comprehensive training regarding downhole tools and instruments; and one lecturer gives a unique training on sales technic.

Schlumberger is well known as the biggest service company in oil & gas industry and the leading company for drilling technology in the world. The cooperation between DeRun Energy and Schlumberger shows the new strategy of Schlumberger on manufacture arm.

DeRun Energy Co., Ltd is visited by Middle East Company

Oct. 18-Oct. 25 2016, DeRun Energy Co., Ltd is visited by Middle East Company. This time the president and vice-president of the company are coming particular to visit DerRun Energy.

That Middle East company is one of the biggest state own company in the country. Currently owns over 80 drilling rigs, working both onshore and offshore.  At present, that company has a workforce of 16,000 employees, working in 10 provinces.  Presenting all the required technical services and enjoying the benefits of its state of the art equipment and skilled man power and expertise.

During the visit, managing director of DeRun Mrs. Sabrina Liu is accompanying. Mrs. Sabrina Liu is introducing the full business range of DeRun Energy, especially for the products of downhole motor, LWD/MWD, advanced drilling tools as well as centrifuge and drilling waste management system. The Middle East Company leaders are showing great interesting. There was a mutual benefit agreement made during the visit for long term cooperation.

In the very near future, DeRun Energy will invest more time and fund in Middle East, to serve better the surround clients.

Sludge/Sewage Dewatering Decanter Centrifuge

The solid drum is internally installed with a concentric discharge screw As they rotate in the same direction at a high speed, They have a certain rotational speed difference, which is caused by the driving system and the differential case Suspension enters the internal of the charge screw through the speed pipe and then goes into the drum after being accelerated Under the centrifugal force, solid particles of big density settle on the inwall of the drun, and form a circular layer of cake, which is continuously pushed by the discharge screw to the small end of the drum end then out of it, while the setlled liquid is continuously discharge out of the drum from the vortex finder of the big end of the drum, hence solid-liquid sparation of suspension.

Application Range:

• Municipal Waste Water Treatment
• Industrial Waste Water Treatment
• Water Plant Sludge Treatment

GAS EQUIPMENTS

DeRun strategy partner of gas equipment manufacture had purchased advanced CNC machining centers, CNC lathes, Bending machine and round tube phase intersecting line cutting machine, high precision digital processing equipment for produce gas pressure regulating box, gas regulator pressure device, A-class pressure vessel, safety cut-off valve etc. Currently the gas equipment had sell to CNPC Kunlun, ENN and other gas operators.
