The drilling fluid vacuum degasser is a new special equipment for treating drilling fluid with gas invasion

Xi ‘an KOSUN VD series drilling fluid vacuum degasser is a new special equipment developed by our factory on the basis of comprehensive degasser at home and abroad. It is suitable for all kinds of mud purification systems, which play a very important role in restoring the specific gravity of mud, stabilizing the viscosity of mud, and reducing the drilling cost. At the same time, it can also be used as a high-power agitator.

**KOSUN drilling fluid vacuum degasser**

The degasser belongs to the drilling fluid vacuum degasser, that is, the suction effect of the vacuum pump is used to create a negative pressure zone in the vacuum tank. Under the action of atmospheric pressure, the mud enters the hollow shaft of the rotor through the suction pipe and then is thrown towards the wall of the tank in a spray shape through the window around the hollow shaft. Due to the impact of the collision and the separation wheel, the drilling fluid is separated into thin layers, and the bubbles immersed in the mud are broken. The gas escapes through the suction of the vacuum pump and the separation of the gas-water separator, the gas is discharged to the safety zone by the exhaust pipe of the separator, and the mud is discharged from the tank by the impeller. Since the main motor starts first, the impeller connected to the motor is in a high-speed rotation state, so the mud can only enter the tank from the suction pipe, and will not be sucked from the drain pipe.

Last week, our factory shipped 8 pcs of drilling fluid vacuum degassers to foreign countries. As supporting equipment of drilling solid control equipment, this equipment provides a safety guarantee for drilling.

Introduction to Mud Agitator and Reference for Selection

The Mud Agitator is an efficient mud mixing machine. Through customized size and configuration, it can meet the requirements of different types of mud tanks. How to choose a suitable model reasonably has become an important factor that technicians have to consider when designing.

The Mud Agitator is fixedly installed on the top of the mud tank, and the stirring rod impeller sinks into the mud. The stirring shaft and the motor are connected through a coupling, and the rated power is from 7.5 hp to 20 hp (5.5kw ~ 15kw). The selection of agitator should consider tank size, depth, and mud parameters. Generally speaking, single-layer impellers are used below 11kw, and double-layer impellers for 11kw and above. It depends on the depth of the slurry tank used on site or customer requirements.

The impeller of the Mud Agitator is fixed on the shaft by bolts to prevent the impeller from rotating and shaking during the mixing process. Normally, the impeller is installed at a height 3/4 times the diameter of the impeller from the bottom of the tank. For example, if the diameter of the impeller is 600mm, the impeller needs to be installed at a height of 450mm from the bottom of the tank. Guanneng Company recommends the use of a vertical impeller when the tank height is less than 1500mm, and an inclined impeller when the tank height is deeper. If a double-layer impeller is used, the vertical impeller is installed at the bottom, and the inclined impeller needs to be installed at 2/3 of the height of the tank bottom.

There are three types of mud shale shaker motion.

In the process of oil drilling drilling fluid from internal carotid out through shale shaker, then in other solids control equipment, in the solid phase removal equipment of shale shaker is itself a filterability spate separation equipment, in the mud of a complete set of cleaning system, it has the first, the characteristics of fast drilling fluid solid phase separation, at the same time is also a kind of economic, efficient spate separation equipment.

There are three types of mud shaker motion: circular, elliptical and linear motion, the oscillator in the center of gravity, will produce circular motion; When the oscillator is above the center of gravity of the system, elliptic motion is generated. However, for elliptic motion, the screen surface must have a slope in order to utilize the conveying cuttings, but the screen capacity will be reduced. The linear motion is to put the oscillator in front of the center of gravity of the system, making the screen frame produce linear motion, thus clearing the solid phase. The vibrating screen moves in a straight line with its fixed cuttings transfer speed. The screen surface can be flat or slightly tilted.

The ES series elliptic vibrating screen of KOSUN adopts the long tube vibrating motor as the power source, the performance is superior, the structure is reasonable, the operation is stable, the life is long, the maintenance cost is low. Under the same conditions, compared with other types of shaker, drilling mud processing capacity and sand transport and discharge capacity can be greatly improved, and can effectively overcome the “screening”, “screening paste” phenomenon.

KOSUN LS series linear vibrating screen using the vibration motor excitation to cheer for the vibration source, make the material being thrown up on screen, at the same time, forward a straight line with low consumption, high output, simple structure, easy maintenance, fully closed structure, no dust overflow, and the advantages of automatic discharge, more suitable for assembly line, at the same time family newsletter QZS linear vibrating screen can also be adjusted through the AWD regulating series of solid separation effect.Linear vibrating screen has obvious advantages in the treatment of large displacement drilling fluid. In this condition, the strong excitation force output by the linear vibrating screen can quickly remove a large number of solid phases through efficient linear vibration trajectory, which can effectively remove large particles in the drilling fluid.
