Unique Selling Point Of DCZCQ Vacuum Degasser

Vacuum degasser is an important degassing equipment for oilfield drilling fluid processe system. Which located preliminary to the shale shakers to remove and break the big bubble. There are 4 models of vacuum degasser commonly used in current markets: ZCQ240, ZCQ270, ZCQ300 and ZCQ360. The details introduction please click our official website.

vacuum degasser

The DCZCQ Series advanced degasser is designed to remove virtually all entrained gases, including hydrogen sulfide and corrosive oxygen from drilling fluids. The degasser reduces the threat of dangerous and costly blowouts caused by re-circulating gas-cut mud.

degassing equipment

Unique Selling Point Of DCZCQ Series Vacuum Degasser:

1. Simple operation adds to safety
Gas-cut mud is drawn into the tank through a vacuum created by the discharge jet and the pump. The mud is dispersed in a thin layer over the full-length baffle and, as the entrained gas is freed, it is recovered by the vacuum pump. The gas is discharged at a safe distance from the drilling operation while the restored mud is returned to the drilling fluid system.
2. Ease-of-installation for self-contained unit
Skid-mounting simplifies spotting and installation. The self-contained unit consists of a cylindrical vacuum tank with an internal baffle system, vacuum pump, jet nozzle and three-way float valve. The unique design of the three-way float valve allows venting to the flare line during hydrogen sulfide service.
3. Simple design/exemplary results
The vacuum degasser features only three moving parts: the float inside the vacuum vessel, the vacuum breaker valve, and the vacuum pump.

You are welcome to contact with us to get more detailed infos, we will supply cost-effective vacuum degasser and satisfactory pre-sale, sale and after-sale technical services.

Three phase decanter centrifuges from DC solid control for sale

To be as a leader of wasterwater treatment company. DC Solid control developed a 3 phase decanter centrifuge used in oil and gas field and all kinds industries wastewater treatment projects.

The three phase decanter centrifuge. It is made of cone drum, spiral unloader, differential system, bearing base, engineer base, main motor, back motor and electrical system.


Working principle of 3 phase decanter centrifuges:

Under the great centrifugal force of the high rotatry speed of the centrifuge can make the material continous used in 24 hours. Main motor drive the drum through the belt will produce a rotation speed differential based on the braked differential drive the back motor to realize the material hydration and pushing function. The centrifuge have the function of differential speed auto control, because of the feeding material content the solid ration maybe have fluctuate, use the differential speed control system to ensure the differential speed is steady to make the better separation effect.


The heavy and  light liquid phase is discharged respectively from the heavy and light liquid phase outlet to reach the liquid, liquid and solid three phase separation. The centrifuge have the ideal seal properties, material dehydration working is in a state of full sealed, and make the working environment is clean.

All of DC Solid control decanter centrifuges adopt the international advanced special structure design. The centrifuge has the advantages of superior quality and efficiency, with larger treating capacity , better separation effect and easy to operate.

The machine has the certificated of ISO9001-2000. Mechanical properties is higher than JB/T502-2004《spiral sedimentation unload centrifuge》standard.

20 sets drilling fluid agitators got to railway station

Yesterday, the 20 sets drilling fluid agitators transported to railway station already and prepare to shipped to Russia. Although, the economic of Russia is not well, but not effect the my Russian clients drilling operations. The big service company from Russian also has 20 rig working in different ares and ordered 6 sets solid control system in droves in last 2015.

At the end of 2015, the clients re-placed an order of 20 sets drilling fluid to equipped with their ZJ40 drill rigs. DCSJBQ drilling mud Agitator adopts the blender cycloid speed reducer, and it is applied to the drug liquids mixing tank. This mud agitator has the advantage of compact structure so it occupies small area.

Mud agitators

DCSJBQ Series mud agitators serve three purpose:

1. Ensure mud additive are homogeneously mixed, preventing spot over treatment of chemicals, dilution water or weighting agents.
2. Prevents the pits from” gelling”,by keeping the active mud system moving when the mud pumps are disengaged.
3. When drilling with weighted mud, properly sized agitators will keep the weighting agents in suspension, minimizing solids from settling in corners or dead spots of the pit.

More than 7.5 kW Mud Agitator uses the turbo and worm gear speed reducer, with the large torque transmission、 the  revolution is steady、it works reliabily and has great merit. Common   model of mud agitator is JBQ5.5kW 、JBQ7.5kW 、JBQ11kW and JBQ15kW. The drilling mud agitator is an important agitating equipment for drilling fluid circulation system.

DC offers a variety of motor and impeller sizes to fit specific tank configurations. Please tell me your tanks depth and motor power that you need when send inquiries to us.
