Specifications for electric motors in mud agitator

The motors in the mud agitator all use explosion-proof T-frame, 3-phase 230~460V, 1150 rpm, frequency 60 Hz; or 3-phase 190~380V, 958 rpm, frequency 50 Hz. Flexible coupling for motor The joint is directly connected with the reducer. A strong steel passport is mounted above the connecting shaft.

The solid mild steel shaft is connected to the reducer with a rigid coupling. In order to adjust the height of the impeller, a keyway is opened in the lower part of the shaft. The diameter of the shaft ranges from 38.1 mm to 88.9 mm, depending on the model, and the actual length of the shaft is determined by the user.

How to calculate the size and number of mud agitators

In the equipment currently in use, it is very likely that 75% of the mud agitators are installed improperly. The reason for this situation is either not understanding the correct size determination method, or not understanding the importance of selecting the size reasonably. The reasonable stirring amount calculated by each agitator is related to the given power and impeller diameter. The relationship between the mixing range that the impeller can reach and the specific gravity of the mud and the required power can be determined by calculation.

Factors Affecting the Use Effect of Decanter Centrifuge

The decanter centrifuge is mainly composed of a rotating drum, a spiral, a differential system, a liquid level baffle, a driving system and a control system. It is a special equipment for solid-liquid separation designed for the characteristics of petroleum drilling fluids. It can complete various processes such as feeding, centrifugal sedimentation, and unloading at full speed. It is mainly used to recover barite, remove fine solids, and reduce drilling fluids. The solid content of the drilling fluid controls the density and viscosity of the drilling fluid, ensures the performance of the drilling fluid, and plays an important role in rapid drilling.

Factors Affecting the Use Effect of Decanter Centrifuge

The use effect of the decanter centrifuge is divided into adjustable factors and non-adjustable factors. Now we will explain them separately. If we understand the principle of action, we can effectively control it in use. The unadjustable mechanical factors include: drum diameter and effective length. Drum half cone angle. Pitch. Screw type. Adjustable mechanical factors are: drum speed, differential speed (difference ratio), liquid ring layer thickness, process factor.

There are many factors that affect the dewatering effect of the decanter centrifuge, and each factor affects each other. Therefore, the treatment effect is the result of the combined effects of the above-mentioned factors. The selection of the centrifuge should be carried out in accordance with the actual situation of the project, and the operating parameters should be adjusted. It should be considered comprehensively from the expected mud cake moisture content, solid content and economic efficiency required by the disposal method of the dehydrated mud cake.

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.
