Centrifugal pump Mechanical seal

There mainly 3 sealing types for centrifugal pumps, like shearing pump, sand pump , slurry pump, etc…

1) Asbestos packing

2) Arid seal

3) Mechanical seal

Mechanical seal is the greatest and many costive sealing types. It’s reliable with an extended lifetime.

The fundamental meaning of Centrifugal pump Mechanical seal

Mechanical seal is the seal device for rotary machines. Like centrifugal pumps, centrifuges, reactor along with a compressor equipment. Since the transmission shaft goes through within the inside and outdoors from the equipment, so, the presence of a circumferential clearance between your shaft and also the equipment, equipment of medium leakage outwards with the gap, when the equipment within the pressure is gloomier compared to atmospheric pressure, air towards the equipment inside leakage, and for that reason it has to possess a package to avoid leakage from the shaft. Many seal species, because of mechanical seal has the benefits of little bit of leakage and lengthy service existence and so forth, so in present day world, mechanical seal is sealed within the primary shaft from the equipment. Mechanical seal can also be known as the face area seal, within the relevant standards from the condition is understood to be: “by a minimum of a set of finish faces vertical with respect towards the axis of rotation within the fluid pressure and also the elasticity of compensation organizations (or magnetic) device function and coordination of auxiliary closes to help keep integrating carefully relative sliding form to avoid fluid leakage.

Review of concepts on Centrifugal pump Mechanical seal

Mechanical seal is as simple as a set of or number around the vertical axis for finish face relative sliding within the fluid pressure and also the compensation mechanism of elastic (or magnetic) under the act of coupled with keep adhering auxiliary sealing and leakage potential to deal with seal device.

Common mechanical seal structure comprises an immobile ring (static ring) 1, rotating ring (dynamic ring) 2, 3 elastic components, a spring chair 4, fastening screw 5, a rotating ring auxiliary seal ring 6, and also the static ring auxiliary seal ring 8 along with other components, anti rotation pin 7 is bound around the cover 9 to avoid static the rotation from the ring.

Rotating ring and also the stationary ring is frequently may also based on when they have been the axial compensation capacity and it is known as the compensation loop or non compensation ring.

As well as for its primary feature that we will talk in next paragraph, it is usually utilized in core drilling.

GN mini decanter centrifuge using the model GNLW223 mainly occupied the next features.

1. small footprint for simple moving and narrow working space

2. One motor driven mode for the bowl and inside screw propeller. The motor drive the bowl using a belt lever with devices, the bowl has same rotation speed because the motor. Meanwhile, the style of gear unit helps make the input speed from the screw propeller is a lot less than the bowl ¨C the screw propeller can also be driven through the motor having a belt lever. Thus the presence of the differential speed results in the centrifuge working availability.

3. High typical accelerate to 4500 make the sufficient G pressure to split up the fine solids with size 2~5 microns.

4. Material of SS304 on bowl, screw conveyor and primary body and protection of tungsten carbide squirting welding is perfect for lessen the cost, but could satisfy the working demand well.

5. Both fixed speed and variable speed model can be obtained

GN Solids Control Equipment Reduce Your Environmental Footprint

GN Solids control system involves the utilization of shale shaker, mud cleaner and decanter centrifuges to process drilling fluids and remove the expected solids prior to, during, and after the drilling operation. We mainly supplies three phases of solids control system including prior to drilling: mud mixing system, during drilling: mud reclaim system and after drilling: drilling cuttings waste management system.

GN is highly experienced in offering qualified solids control equipment for all types of drilling fluids in the world.

Prior to Drilling

Mud mixing system is applied for mixing all kinds of chemical to formulate the drilling fluids. Generally, we apply the centrifugal pump, venturi hopper even shear pump for circulating and mixing drilling mud. The capacity of centrifugal pump ranges from 200GPM to 1408 GPM. Shear pump is capable of reducing the cost of mixing polymers an clays while improve the mud properties. Also, we utilize the mud agitator and mud gun to suspense solids prevent from sediment. Regarding to the customer’s requirement, we are able to customize the length of shaft of mud agitator and length of mud gun

During Drilling

Solids Control equipment are capable of reclaiming the drilling fluids. Technically, we offer the series of equipment including shale shaker, desander, desilter the combination of desander cones and desitler cones and decanter centrifuge. The four steps of solids control equipment remove different size of solids in order keep the drilling fluids property

After Drilling

Drilling cuttings waste management system is use for processing the drilling cutting s during drilling and after drilling. Especially, drilling cuttings waste management system is for offshore project. When offshore project produce some drilling cuttings, contractor normally keep the cuttings and subsequently reclaim in the land. Therefore, our drilling cuttings waste management system is widely used for onshore and offshore drilling project. Our field experienced technician staff will work to assure that every project has a solution optimized for the drilling cutting being disposed.

Solids Control Wear Part- Shaker Screen

Within the solids control industry, shaker is the primary solids control unit, and shaker screen is a vital put on part for shale shaker. GN use the advanced technology to produce a number of brand shaker screens. Being an API and ISO licensed company, GN offers from API 20 to API 400 shaker screen.

Top quality and Flexibility Test

GN screens are fabricated in an array of API dimensions to make sure maximum solids control efficiency no matter the formations drilled. Our high-strength and strengthened material frames and stainless steel sieve are lighter and much more durable than usual shaker screen. What results is operational existence that’s nearly double those of other screens available on the market.

GN use constant observation, adjusted test liquids, Dry sieve testing procedure and periodic sampling testing to represent each API sieve class. GN regularly takes shaker screen to check percent elongation, ductility, wire count and tensile strength so assure each shaker screen qualtiy

Although we check carefully each shaker screen, couples of clients still complain the shaker screen blocked. You will find some reason by which make the shaker screen clogged

– How big solids is near to the dimension of opening sieve

2. Drilling liquids/mud is that contains an excessive amount of moisture

3. Particle/solids have static cling throughout the separation process

4. vibrating mesh wire through too thick

5 . The form of huge solids is flaky

6. some thicker kinds of mine screen, pass design is uncommon

Note: the contaminants/solids are essentially irregular shape, therefore the reasons of block are also different. To be able to better prevent screen clogged filter while watching products, perform some analysis and judgment before we decide the shaker screen. When you wish to filter fine contaminants or consists of more mud, water will probably cause blockage from the primary factors sieve. Hence the requirement for moisture testing contaminants, once the water is more than 5%, the requirement for blocking particulate drying out When water is more than 8% use wet sieving. Screening performing and the other reasonable regulation mesh tension can also be a highly effective measure to effectively prevent inserting sieve.
