The solids control equipment of drilling mud shear pump

The Brightway Solids Control  BWJQB series shear pump can produce high performance mud quickly, shorten the mud preparation time, improve the economic efficiency of drilling. Shear pump is added to the raw material preparation of slurry in drilling mud continuous shear, refinement, mixed efficient circulation and change the molecular chain structure of it, the mud to the process and performance of certain requirements, and meet the drilling requirements higher performance of drilling mud solid control equipment.

Shear pump is composed of an impeller, volute, Pan Gen he, drive shaft, pulley ,motor and bearing etc.

Shear Pump

Impeller shear pump impeller is different to other centrifugal pump, its structure is more complex. It mainly consists of axial flow turbine, slurry storage mud tank, pump, pressure tank and cutting board is composed of five parts. Flow turbine shaft ,pump, slurry storage tank for precision casting into a whole, has the advantages of compact structure. It is a core component of shear pump shear, with very high efficiency.

The axial shear pump flow turbine to provide fluid has a certain capacity of pump and slurry storage tank, the fluid through the pump wheel 55% is drained into the vortex shell, 45% slurry storage tank absorption. The unique design of pressurized cabin, the fluid slurry storage tank with a certain power. Fluid from the pump wheel, parallel to the shear flow, high flow.

Slurry storage tank. The liquid, after several jet nozzle to the shear plate injection. The mixed fluid injection liquid and shear pump impeller discharged together, with serrated wheel high speed impact shear plate outside, high-speed rotation of the cutting saw gear, the fluid shear treatment again. Therefore, the fluid flows through the impeller, after repeated s
hear.

Shear pump adopts a very reliable mechanical seal, to ensure no leakage. Because of the improvement of the pump shaft seal, so life is greatly improved. The pump is equipped with stainless steel turbine and a shear plate, can produce liquid shear more than 25.4m/s, when the flow of fluid through the drilling mud shear pump, 5% of the liquid in the turbine collection strongly promote the will be the two shear. The turbine drilling mud shear pump installed in the special base ,and pulley, narrow V belt and 55KW/75kw explosion-proof motor drives. In addition to a size suitable for mixing funnel and the drilling mud shear pump matching, thus formed a perfect shear and hydration system, also called shear mixing jet apparatus.

Solids Phase and Solids Control System

When it comes to solids control system, solid phase should be mentioned. The solid phase of drilling indicates the solid elements contained in mud, the percentage for volume or mass is the drilling fluid solids content we usually say.

Drilling solid, according to their functions, can be divided into two categories: the useful and harmful solid phase. Because of liquid solid content, particle size and the cost of drilling have essential relationship, drilling fluid solids control appears to be very important in drilling engineering.

The mud solids control is to remove harmful solid mud in the solid phase and preserve useful solid prase. In order to meet the requirements of drilling technology on mud properties. Usually the mud solids control refers to solids control, mud solids control system is generic term all the mud solids control equipment. Modern mud solids control is an important means of modern drilling, for it directly affects the safety, quality, fast drilling and protection of important factors of oil and gas reservoirs, it is also an important symbol of drilling into the scientific stage.

Specifically, the mud solids control has the following functions: prevent oil and gas channel blocking, damage, reduce the drilling torque and friction, reduce the annular suction pressure fluctuations, reduce the possibility of differential pressure sticking, improving drilling speed, prolong the life of the bit, reduce equipment wear, improve the life of wearing parts of the mud circulation system, increasing borehole stability.

In addition, using drilling mud system such as mud tank and mud shaker will improve the underground conduit conditions, reduce environmental pollution, maintain the performance and adjust the mud, reduce drilling costs.
