Centrifugal pump/feeding Pump China factory

Usually, oilfield centrifugal pump is a machine which converts mechanical energy into the kinetic energy of oilfield centrifugal pumped fluid for the purpose of transporting that fluid from one point to another.

But in order to be classified as a centrifugal pump, oilfield centrifugal pump needs to have two unique components: the first is a rotating disc with curved blade like vanes on it called an impeller, and the second is a specially shaped pipe called a volute casing which contains the impeller and the pumped fluid.

centrifugal pump

We have many model of the drilling fluid sand pump, the commonly used are SBSB8x6-14, SB6x5-12, SB5x4-12, SB4x3-12 and ect. Usually users selects the centrifugal pump is according to flow rate demand. Furthermore, the flow rate is related with motor power, head, electric system, the impeller size. Centrifugal pump in drilling mud process system is mainly power supply. And pump drilling fluid from mud tank to mud process equipment. Such as desander, desilter, or mud cleaner cones, decanter centrifuge.

Besides, the pump working condition is rather hard by transferring drilling fluids with solid in for a long term. We need the bearing seal to be very reliable and steady. If you have request of any sand pump, please freely to contact DC Machinery.

Decanter Centrifuges in drilling mud cleaning system

Decanter Centrifuges are a key component in drilling mud cleaning on a Drilling Rig solids control equipment to the oilfield. To maintain drilling mud in an optimum condition results in less waste, reduced operating cost and a high efficiency of the total solids control system.

Separation point of decanter centrifuge is as fine as 2~7 microns. According to different rotation speed, there are high-speed and middle-speed centrifuges. It really plays an important role in lower mud density and bentonite recovery.

Features Of DC Decanter Centrifuge
1. Bowl Cylindrical and the Conical section made of Duplex Stainless Steel 2205 by centrifugal casting. Other parts of the bowl assembly are made of stainless steel 316L.
2. Screw protection: Tungsten Carbide Tiles for longer life and easier replacement.
3. Screw flow distribution port and bowl solids discharge port protected by tungsten carbide alloy.
4. Easy to adjust liquid discharge weir height for flexible application.
5. Bowl assembly supported by the tighter belt for the protection of bearing in moving.
6. Pressurized EX Proof VFD control cabinet available.
7. Genuine SKF bearing for longer and reliable operation.

If you have interest with drilling fluid centrifuges, Please contact DC Solid control to get more info about it. DC Solid control company will be your best choice.

DC mud circulation system from China top supplier

The mud circulation system in any rig is as important to a drilling rig operation as the blood circulation system is to the human body.  Any mechanical or technical breakdowns in the mud system can immediately stop the drilling. DC oil drilling mud system is available for different oil drilling rig sizes from 250HP to 3000 HP with different capacity.

Oil drilling Mud System normally including following mud tanks depends on the function of the mud tanks.: 

1) Silting mud tank ( Shaker Tanks)
2) Active Mud Tank
3) Suction Mud Tank
4) Mixing Mud Tank
5) Storage Mud Tank

drilling mud system

Oil drilling mud system including following solids control equipment:

1) Shale Shaker for primary solids control 100 microns.
2) Desander for second phase solids control of cuttings 40 microns.
3) Desilter for third phase solids control of cuttings 20 microns.
4) Decanter Centrifuge for the 2-7 microns fine solids separation.

As the leading manufacturer for oil gas drilling mud system, DC Solids Control products is certified by ISO, Europe CE, and Russia TP and TC. The explosion proof standard can be IEC Ex, or ATEX certified for developed countries for Zone 1 and Zone II application.

Compact structure shale shaker for HDD project

Shale shaker is a core equipment for drilling mud cleaning in HDD and Coal Bed Methan(CBM) application DC supply HDD shale shaker to match HDD drill rig and mud pump for drilling cuttings separation. HDD shale shaker is slightly different design with oilfield shaker because of mud conditions and transport difference.

DC holds DCZS852 and DCZS703 shale shaker as linear motion , DCPS852 and DCPS703 as balanced elliptical motion(BEM) for both HDD and CBM . Also for diamond drilling , rotary drilling, mining slurry separation.

shakes

HDD shaker use 3 decks shaker mostly for 500GPM or higher mud flow capacity because of shorter deck will allow shaker stay on shaker tank while inland transport without disassemble. But oilfield shale shaker normally use 3 decks or 4 decks shaker with buffer box back design to allow mud over flow to reduce mud speed but longer shaker decks which will be disassemble while inland transport.

HDD Shale Shaker Features
1. Non-explosion proof vibrator motors and electrical control panel for cost effective, oilfield shaker is explosion proof vibrator motors and electrical control panel.
2. Buffer box install on top of shaker deck and shaker skid but oilfield shaker buffer box installs on back of shaker deck for mud overflow.
3. 2 decks or 3 decks shaker is well used for HDD drill rig to suit mud flow capacity 100GPM to 1000GPM mud flow by 1 or 2 sets shale shaker.
4. Shale shaker, cyclones, centrifugal pump, mixers installs on one tank to make a system but oilfield tank system normally 2 – 7 tanks system with larger mud storage capacity.

DC build complete line HDD mud recycling system with standard model options 200GPM, 300GPM, 500GPM and 1000GPM mud flow capacity. Please contact us freely for HDD mud
recycling system inquiry.
