The adjustable seater type mud gas separator consists of lifting pipe, foxation pipe and baseboard. The quadrangle of the baseboard are all weld fixation pipe, and each pipe has inserted the lifting pipe. The fixation pipe connected with the lifting pipe by fixation hinge pin, the surface of lifting pipe and fixation pipe all equipped multi-align to grid holes.
Because of the different drilling rig with the drill floor height, so the matched solid control system height is different, so that make the height of the connection mouth of the mud gas separator and solid control system and the ground is changed. The heigh between the primary mud gas separator and the solid control system mouth and the ground is formulated by the drilling users, if there is difference after delivery the equipment, we can alter the located ground of the mud gas separator.
The adjustale seater mud gas separator is a kind of simple structure, reasonable design, conveniently to use and realize easily adjust the mud gas separator supporter.

The centrifuge, in splitting the processed fluid into two streams—the underflow, or ‘‘cake,’’ containing the coarser solids; and the overflow, centrate, or effluent, containing most of the liquid and the finer particles—provides a means of selectively removing the finest, most damaging, solids from the drilling fluid. The removal of these solids in order to control rheology and filter cake quality is the primary reason for centrifuging weighted drilling fluids. When the finest solids are not removed, the only alternative means of reducing their concentration is dilution, always an expensive process.
This application is often described as barite recovery, a term that does not accurately describe the process, leads to confusion, and is frequently the reason for improper centrifuge use. The validity of the term depends in the preliminary acceptance of the idea that the fluid entering the centrifuge would otherwise be discarded and that the barite is recovered by the centrifuge. Few, if any, drilling people think of centrifugingin these terms. Centrifuges, like shale shakers and hydrocyclones, are solids-removal devices. Centrifuging weighted muds while drilling is correctly thought of as an alternative to dilution for the reduction of viscosity; not as a means of recovering barite from discarded fluid. Another objection to the phrase is that it lends support to the idea that barite recovery is the reason for centrifuging. It is not. The objective of centrifuging in this manner is the removal of colloids and ultra-fine solids to improve drilling-fluid quality. A third objection is that the use of the term tends to create the totally erroneous impression that the process separates barite from low-gravity solids and that the recovered material is all barite. A natural consequence of this belief is that the underflow from barite-recovery centrifuges is sometimes stored and used to weight up freshly prepared drilling fluids. Inasmuch as the recovered slurry often contains high concentrations of drilled solids, it can be severely contaminated, and is rarely suitable for reuse.
The role of desanders is to reduce loading downstream on desilters. Installing a desander ahead of the desilter relieves a significant amount of solids loading on the desilter and improves desilter efficiency. High rates of penetration, especially in unconsolidated surface hole, where the largest-diameter bits are used, results in generating larger concentrations of drilled solids. This may place desilters in rope discharge. For this reason, desanders, which have greater volumetric capacity and can make separations of coarser drilled solids, are placed upstream of desilters.
Desanders remove a higher mass (i.e., coarser drilled solids) during periods of high solids loading. Desilters can then efficiently process the reduced solids-content overflow of the desanders. If the drill rate is slow, generating only a few hundred pounds per hour of drilled solids, the desander may be turned off and the desilter used to process the entire circulating system.
When separator operation is no longer feasible due to high proportions of solids in the suspension to be processed, decanters are used. Decanters are horizontal, solids-oriented, solid-wall scroll centrifuges.
In solid-based applications, our centrifugal decanters ensure optimum separation efficiency, particularly in the case of suspensions with a very high proportion of solids. They are also used for the extraction of constituents from liquids and for concentrating, dewatering and classifying solids.
Whenever the clarified liquid is dischaged from the decanter bowl a throttle plate moves along its axis and determines the gap width of the aperture. Intelligent sensor technology recognises the throughput volume necessary at any specific time and regulats the gap width as a function of the liquid level in the decanter bowl by moving the throttle plate to the optomum position while the machine is running. With varipond, decanters always opertate with optimum efficiency and with much lower operating and maintenance costs. All down stream process are thus optimised too.
The decanter centrifuge application areas include the cleaning of wash water and the treatment of fruit and vegetables in the food industry, the recovery of animal and plant oils and fats, the production of herbal medicines, copper extraction, chemical extraction in the paper industry, the treatment of waste oil for power generation, waste water treatment in waste water treatment plants, and use on oil platforms for the extraction of crude oil.
Mud Cleaner is also called Desander and Desilter assembly. It is the second phase or the third phase solids control equipment, Namely, mud cleaner consists of a two-stage separation process using a combination of hydrocyclones frame mounted over a shale shaker to operate as a single unit.
Mud conditioner is effective on processing both weighted and unweighted drilling mud during mud systems in removing and drying solids while retaining the expensive drilling liquid. Used correctly, the drilling mud cleaner would greatly lower both drilling-fluid and disposal costs.
The feed slurry of solids and liquid is fed through the inlet at a high velocity obtained by steady pressure of twenty-five .The high velcocity transmitted to the feed section creates a spinning veclocityand resurting centrifugal forces.The vortex finder causes the stream to spiral downward towards the hydro cyclone wall,in a downward spiraling stream. The solids seperate according to size and weight particles.In the destiney range of particles in drilling fluids ,size is of far more influence than the variations in density so that basically the biggest particles settle first and fatest.

1. A mud cleaner should be installed on a flat base or installed directly on the ground.
2. When installing a mud cleaner, the direction of water flw and pipeline should be noticed.
3. The layout of mud tank surface should take inside the space for operation. Since the equipment has no moving parts when working, namely, the equipment is maintenance free. But it is needed to keep the entrance load stable, open and close the sewage valve evenly and avoid man-made damage.
1. Unauthorized disassembly of mud cleaner is not allowed.
2. A mud cleaner is generally installed after a deep well pump.
3. If the system is faced with a long time stop or seasonal stop, before the stop, adding appropriate amount of corrosion inhibitor in the water, and take full moisture protection measures, in order to reduce the corrosion and protect the system.
