Shale Shaker-Basket Mechanism

The shale shaker basket should be capable of adjusting its angle to accommodate numerous flow rates of drilling fluids in the solids control system and to maximise the utilization of the shaker bed, this can be wherever the fishing mechanism plays a vital half.
The lubricant flowing over the shaker bed is selected into 2 categories:
Pool: that is that the space of the screening deck that consists principally of lubricant with trained cuttings suspended inside it.
Beach: is that the space wherever the fluid has been principally faraway from the cuttings and that they begin to appear sort of a pile of solids.

As a rule of thumb the Beach and pool area unit maintained at a quantitative relation of eightieth pool and two hundredth beach, this in fact will modification reckoning on the necessities of cutting waterlessness and flow rates.

The mechanism plays an important role in solids control.
There area unit numerous fishing mechanisms presently in use that vary from hydraulic to gas and mechanical, they will be controlled from either one facet of the shaker or should be adjusted one by one per facet. Mechanical fishing mechanisms usually will be terribly dependable often requiring less maintenance however typically take longer to control than their hydraulic or gas counterparts wherever because the hydraulic/pneumatic fishing mechanisms area unit a lot of quicker to control and need less a physical means that of operation.


Brightway Shaker deck angle adjustment:
There are lifter, pipe, lifter pipe, scale indicator, scale, connection plate, etc. When we make adjustment, handle wheel rotary by clockwise, shaker deck angle will be larger; handle wheel rotary by anti clockwise shaker deck angle will be less.
Shale shaker output angle adjustment can be operated under running and off. When finish the shaker deliver it, the shaker deck is 0°. When user operate shaker, according to drilling mud property and flow rate on job site, and adopts same shaker screen, the angle is higher, the treating performance will be better while treating capacity will be higher. When drilling fluid is leaking on shaker deck, increase deck angle can get rid of fluid flow away.
Angle is 0~ +5°

HOW JET MUD MIXER WORKS

The JET MUD MIXER is used to make up drilling fluid or increase total amount of the drilling fluid, change the fluid density, viscosity, and dehydration. When making up again, put the materials of drilling fluid (such as betonies and barite powder) and corresponding chemical additives (such as polymer) into the recycle tank through the jet unit. If put them directly, the materials of drilling fluid and chemical additives will be deposited largely or dump together and we can’t obtain diffused and well-proportioned drilling fluid.

BWSLH jet mixing device is a unit used together with the solid control system for petroleum drilling. It is suitable for drilling from 1,500 meters to 6,000 meters and can strengthen and make up drilling fluid through the fixed control system horizontally. The unit includes one sand pump, one jet mixing funnel and one jet mixer that are installed in a base with pipe valves. It is safe and stable and can be moved conveniently.

Installation and Application

1. Installation

(1) According to the on-site situation, the tank should be at the same level as the slurry tank.

(2) Connect the suction inlet of the pump to the tank body with hoses.

(3) At the outlet, connect the jet mixing to the inlet of the tank with creeping pipe.

(4) Switch on the power, and see if the rotation direction of the sand pump is right.

2. Application

(1) For operation and maintenance of the sand pump, see its operation and maintenance instructions.

(2) BWSLH jet mixing device is shown as the figure.

(3) Before use, open the inlet butterfly valve of the sand pump. Then start the sand pump. When the sand pump runs normally, open the inlet butterfly valve of the funnel, then add the materials of drilling fluid (such as betonies and barite powder) and corresponding chemical additives (such as polymer) from the funnel to strengthen and make up the slurry.

(4) Before stop the pump, close the inlet butterfly valve  of the funnel to prevent the instant pressure decrease, which resulting in overflowing of slurry from the surface of the funnel.

(5) In winter, when BWSLH jet mixing device stops working for a long time, close the suction inlet butterfly valve 1, then loosen the pipe plugs under the casing of the sand pump and ones under the inlet pipe of the funnel to drain the slurry to prevent the pump body and pipeline from being blocked and frost cracked.

Comparison Between Brandt Mud Agitator and Brightway Mud Agitator

Let's have a comparison between Brandt mud agitator and Brightway mud agitator.

HIGH QUALITY AND TIME-PROVEN MECHANICAL AGITATION
Agitators serve the drilling industry with high quality and time-proven mechanical agitation.
VMA
The VMA agitator is vertically mounted, reducing the footprint requirement. It offers a motor with a vertical direct mount to a helical inline gearbox with a drop bearing configuration.
Impellers
Impellers are available with flat blades (radial flow), contour blades (axial flow) and canted blades (radial/axial flow). The impellers are sized according to tank volume and expected duty. Active mud system compartments - such as solids removal sections, mud mixing sections and slug pits - which need a higher shear force to produce immediate mixing, are another consideration in impeller sizing.
Shafts
Several types of shafts are offered.Mild steel shafts are cut to length and joined to the gearbox output shaft with a rigid coupling. Solid shafts are keyed at the bottom for adjustment of impeller height. Hollow pipe shafts are available for deep tanks. They are supplied in flanged sections and bolted together making them ideal when lifting height is limited.

Brightway oilfield mud agitator features a “C” face motor couple to a rugged oilfield gearbox, which eliminates misalignment and troublesome couplings. This configuration promotes long motor and gearbox bearing life. Mud Agitator is used in mud systems to suspend solids and maintain homogeneous mixture throughout the system.

Mud Agitator Features and Benefits

1. Structure: Small footprint and compact structure

2. Reduction gearbox: Helical-bevel design or worm design according to customer requirement

3. Motor: Explosion-proof electrical motor, and can be the style of horizontal or vertical

4. Shaft and impeller: Galvanizing treatment brings the excellent anti-rust performance much better than the painting process

5. High efficiency, low noise, low operating temperature.
