What is mechanical seal?

Mechanical seal is a device which to prevent liquid under pressure from leaking out of the pump, or from drawing air into the pump when under vacuum conditions.

Mechanical seal centrifugal pump is a type of Single-stage & single-suction mud pump, Material of pump housing, stuffing box, impeller, bracket mount is Grey iron casting HT250, and pump shaft is made of 42CrMo, Mechanical seal material including :

Rubber material is viton

Skid, spring is made of SS316

Surface of seal is made of tungsten carbide

For  multi-tank mud system,usually,we use horizontal sand pump for feeding the desander and desilter,but for HDD mud system,many clients just require for a single mud tank system,to save the space for storing mud and also to make the manifold to be simple.We install the submersible,vertical sund pump for desander and desilter mud feeding.

Both horizontal sand pump and vertical sand pumps are used in HDD(horizontal directional drilling) and oil gas drilling fluids system.

Horizontal sand pump

Horizontal sand pump

  • Horizontal sand pumps

Horizontal sand pump is an important equipment in oil rig mud cycling system, be able to deliver corrodive drilling fluid(with suspended particulates) or other liquid media under similar work condition, are the best optional pumos of sand removers, mud recovers and mixing hoppers as well as perfect perfusion pumps of mud pumps. For design of their parameters, that equipment with which such pumps are used together can operate under the best work condition has been fully considered. These pumps are mainly characterized by good versatility and exchangeability of parts, less leakage of shaft seal, reliable operation, long service life and convenient maintenance.

Horizontal sand pump are used for feeding drilling fluids mud cleaners,mud desander,desilters.And provide the force for particle separation of drilling fluids.

  • Vertical Sand pump Application Instruction

Vetical sand pump in drilling mud circulation system is usually submersible pump,it usually used to feed drilling mud decanter centrifuge,and sometimes also used to feed mud cleaners,desanders,desiters. Continue reading »

SB Sand Pump Operations

A. Preparations

(A). Inspect the rotating direction

(B). Rotate the pump shaft by hands and ensure that it rotates smoothly

(C). Fully open the valve at suction section.

(D). Fully fill the pump and suction piping with liquid in order to eliminate air in them.

(E). Open all the cooling water-pipes.

(F). Lightly open the valve in delivery pipe system (if using a vacuum pump for priming, the valve must be fully closed before starting the main pump).

B. Operation for Running Sand Pump

(A). Start up the motor after all the preparations is finished.

(B). Gradually open the throttle valve of outlet after the pump pressure is stable and close it if no liquids flowing out. Gradually re-open it after the pressure is stable and until the capacity is normal.

(C). Operating conditions

a.Speed:1480r.p.m

B.Max Pressure: 10.5Kgf/cm2

c.Max Temperature:120℃

Sand Pump is the ideal equipment to provide impetus for DesanderDesilter and Jet Mud Mixer. It can also be used as Charge Pump auxiliary perfusion for mud pump and Trip Pump for drilling well head

Definition of centrifugal pump
Machine for moving fluid by spinning it using a rotating impeller in a casing with a central inlet and a tangential
outlet

Note of Centrifugal pump:

NOTE The path of the fluid is an increasing spiral from the inlet at the centre to the outlet, tangent to the impeller annulus.
In the annular space between the impeller vane tips and the casing wall, the fluid velocity is roughly the same as that of
the impeller vane tips. Useful work is produced by the pump when some of the spinning fluid flows out of the casing
tangential outlet into the pipe system. Power from the motor is used to accelerate the fluid entering the inlet up to the
speed of the fluid in the annulus. Some of the motor power is expended as friction of the fluid in the casing and impeller.

These centifugal pumps are developed and fabricated  as supporting pumps based on requirement of transferring oil & gas drilling fluid. Centrifugal pump adopt the axial sucking structure and all the hydraulic components are wear proof cast iron, which is suitable for delivering the corrosive liquids with suspended particles in well drilling. Its quality is accepted by Weatherford and assembling dimension is same to Mission centrifugal pump.

SB centrifugal pumps are characteristic of abrasion resistance, smooth and stable running, reliable sealing, long service life and convenient maintenance.  Those pumps have been used for land and offshore drilling platforms in more than 20 countries over the world.

Clockwise pumps and anti-clockwise pumps are available.

Mechanical seal and compound seal are available. The compound seal adopts auxiliary impeller, special oil seal and packing seal. Main seal of mechanical  seal is mechanical seal with a long service life, auxiliary seal of machine seal is packing seal to prevent occurrence of accidents.
Shaft seals are lubricated with grease and bearings are lubricated with machine oil and grease  Since bearing covers at two ends of bearings are equipped with grease injectors.

Both inlet flanges and outlet flanges for centrifugal pump are with two series standard dimensions.

Centrifugal pump are widely used in oilfield drilling equipments and drilling mud equipments like shale shakers,desanders desilters etc.Top China  Centrifugal Pump company for drilling mud,welcome to consult us for centrifugal pump for oilfield drilling projects.We supply centrifugal pump worldwide.
