Name of the student Institution Professor Date of submission Feasibility study 1.0 Introduction Mud Agitator can be described as an instrument which is used in mud surface system to help in suspending the solids and also help in maintaining the homogeneous mixture throughout the system (Van Valkenburg, Paul, et al., p 53). This instrument is driven by an explosion-proof motor for the mechanical one, and it is coupled with a gear box that helps in driving the impeller shaft (Van Valkenburg, Paul, et al., p 53). This paper analyses the Feasibility study to change from the permanent vertical type Brandt VMA SERIES VERTICAL MUD AGITATOR 25 HP to horizontal type 25 HP MA-25 RG ASSEMBLY. The main areas of the feasibility include:- Measure how beneficial or practical the change. Problems Analysis for VMA Vertical type as facing frequently worn out in shank pinion and helical gear. Horizontal Agitator type MA-25 RG specification (maximum mud weight and max mud viscosity). Operational feasibility is the problem worth solving or will the solution to the problem work. Is the advanced technology or solution practical? What’s the required to install the horizontal agitator type 25 HP MA-25 RG ASSEMBLY on top of 13 feet deep tank? (Frame, Locate and weld mounting plate. Attached some photos and drawing for the vertical type to see if it is possible to install and fit direct or need some modification. Feasibility can be described as the process of establishing the viability a project hence the study aims at establishing the viability of change from permanent vertical impeller shaft. 2.0 BRANDT Agitators These instruments serve the drilling industry with very high quality and a time frame proven mechanical agitation. The same functionality and design are shared by the VMA-I agitators with VMA. Normally the gearbox is equipped with a strong output shaft that has bearing and not the drop bearing configuration (Rodrigues p23). The first VMAI is vertically mounted on the motor with some helical inline gearbox. VMAI are heavy duty mechanical mixtures which utilize viscous fluids in its operations. The MA-RG, on the other hand, are horizontally mounted motor with the helical-bevel gearbox (Rodrigues p23). Its gearbox utilizes a helical bevel gear drive system that helps in reducing the rotational speed for the motor to help in driving the impellers. 3.0 Benefits of the Change The change VMA can be used in the variety of location which gives it an advantage over the initial VMA vertical type hence it is very much economical (Hall p 43). This agitator help in reducing the cost of mud by almost 30% hence it is beneficial for the construction company. This new change help in having few marks in the mud due to fewer footprints. The instrument is more efficient and helps in lowering the operation temperature hence ideal for use (Van Valkenburg, Paul, et al., p 53). Lastly, we can state that the instrument is smooth, and it operates with no vibration hence very ideal for use in all the environment and conditions needed by the operators. 4.0 Problems with VMA Vertical The viscosity modifying admixtures are used to stabilize the rheology of the SCC. They increase viscosity and helps in thickening the mixture to help in preventing the segregation. The viscosity buildup comes from the association and entanglement of polymer chains of the VMA at a minimum shear rate which further prevents flow and increase of viscosity. Furthermore, additional of VMA normally causes the shear thinning behavior, decline viscosity, when there is an increase in the shear rate (Götz, and Lena p45). VMA in most cases is used alone though there are some instances where they are used with super-plasticizers, and super-plasticizers can take the function of enhancing the flow while VMA provides stability (Rodrigues p23). The problem of worn out and shank pinion can be reduced by level of mixture of the constituent of VMA hence obtaining adequate VMA in a Superpave mixture requires the mix design which must meet all the requirements. 5.0 Horizontal Agitator type MA-25 RG specification The new MA-RG series mud agitators are normally horizontally mounted with the motor and helical bevel gearbox. The MA-RG are heavy duty mechanical mixers which are used for viscous fluid like the ones used for drilling. The gearbox uses a helical-bevel gear drive system that helps in reducing the rotational speed of the motor to help in driving the impellers (Lin, Song, et al. p67). The MA-RG series agitators are compact in nature, their low profile nature help in reducing the headroom requirements and help in providing more layout space on the top of the tanks. Should the impeller encounter a sudden shock load, the height of 1: 1 to the ratio of the width provides the resting base hence stability. Some of the specifications include:- Dimensions of the shaft and impeller are 67.25 in x 33.25 in (1705 mm x 859 mm x 648 mm). The weight is 2022 lb (917 Kg) less shaft and impeller. The gearbox is Helical – Bevel. The nominal gearbox ratio is 29:29:1. The maximum toque is 75,225 in-lb (8,499.28 Nm). The impeller shaft diameter is 3.5 in (88.9 mm). Lastly, the impeller shaft weight is given as 32.7 lb/ft (48.7 Kg/m) (Lin, Song, et al. p67). 6.0 Operational feasibility is the problem worth solving From the proposed problem of VMA of difficulties in obtaining adequate voids in the mineral aggregate, there is need to solve this problem. The problem mixes typically will have low VMA and will be non-responsive to changes in gradation. Therefore, it goes without saying that when the improvement has been made, then it is worth solving. The MA-RG are explosion proof motors and starters which are optional in nature. They help in providing optimal mixing which is efficient in reducing the helical gearbox (Lin, Song, et al. p67). The MA-RG machines operate at a 95% efficiency level hence it is worth investing in. 7.0 Proposed technology The technology proposed to ensure efficient function is the MA-RG agitator who uses a lower profile version of the MR-RG. This will be possible of a base plate is used instead of the mounting skid to help in reducing the overall height. The proposed technology is worth using since it helps in increasing the reliability with lower maintenance frequency while maximizing the triple reduction (Van Valkenburg, Paul, et al., p 53). Normally it will help in reducing the helical bevel gearbox which is driven by a motor which is explosive proof. 8.0 Installation procedure Drill a hole: - The drilled hole must be within the acceptable dimension. The A 1:12 cone rate must also stick to the required specification. The required hole must be a given requirements 0.05. The roughness should be from Rz = 10-30 um for the best results. The setting procedure should be followed with the appropriate setting hole facing the out the LP-plug is inserted in the con bore. The sleeve should not be above the surface of the material base. It is preferred to limit travel when using a press due ti insertion force is difficult to control using the recommended setting speed is 5 mm/sec. Then drill out in one process to the next large diameter nominal diameter d4 according to the data sheet. Clear chips, remnants of the sleeve and oil and grease from the bore. The installation chart process includes:- The MA-RG Series Agitator is designed for years of dependable service with routine inspection and maintenance. Additional copies of this checklist should be placed close to the unit for quick reference. Some of the vertical The vertical gradation effect. The changing of the gradation of the mixture will influence the amount of space in the aggregate skeleton. The overall installed MA-RG is shown in the figure below:- The overall installed MA-RG is shown in the above diagram above. In conclusion, this project is viable and should be undertaken.
