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 :

What is slurry pump?

A Slurry pump is a type of centrifugal pump in physics principle that increases the pressure of liquid and solid particle mixture, through centrifugal force (a rotating impeller) and converts electrical energy into slurry potential and kinetic energy.

slurry pump

There are 2 kinds of slurry pump, horizontal type and vertical type, for vertical type pump, there are submersible slurry pump and underwater pump. Submersible slurry pump is widely used for drilling fluids transferring, underwater pump is used for fluids transfer. Horizontal slurry pump is also used for drilling slurry transfer, just the installation method is different to meet different mud tank size.

What is vertical slurry pump?

Vertical slurry Pump is the cantilever pump structure of single stage and single suction, with the bearing housing, supporting, intermediate pipe connecting the pump hydraulic components, the water is discharged out from the drain pipe parts, pump impeller is for semi-shrouded with the agitating vane on the vane extended, the main characteristic of this pump is the underwater pump shaft parts have enough rigidity, the impeller and pump shell have no bearings, no shaft seal, which can transport the greater medium of solid particles. The length of inserting the water by pump is between 800 and 2000, the suction pipe can be matched in case of need. Continue reading »

Centrifuagal pump is widely used, in all the industry and agriculture even in the life. In the oil well drilling, or just water well drilling, HDD, environment protection, they are core parts though there are a lot of equipments. They charge the transportation for the separation work.
What they really do is pump the mixture of solids and slurry or drilling fluids from one stage of separation to another stage. As shown in the picture. centrifugal pump in the mud system

In the jet mixing system, they pump the fluids to go through the venture hopper, then the chemical things or other materials can be added. and then go back to the tank.

Components of Centrifugal Pump
The components of this kind of centrifugal pump, for separation work, is a little different from the others, though the structure is still the same.

The Definition of Centrifugal Pumps

Machine for moving fluid by spinning it using a rotating impeller in a casing with a central inlet and a tangential outlet.

Centrifugal pump design

The overwhelming majority of contractor pumps use centrifugal force to move water. Centrifugal force is defined as the action that causes something, in this case drilcentrifugal_designsling fluids, to move away from its center of rotation.

Submersible sand pump

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 »

Shale shaker,desander,sand pump,and decanter centrifuge are main equipments for drilling mud solids control,the flowing is the report of using conditions for 13 oil wells.

In 13 oil wells, 5 wells use ZS2×1.15×2/3P low-frequency shale shaker, two wells teams using QGZS-G4 Ⅱ high frequency shale shaker, six wells teams using the DHL-1 high-frequency shale shaker. Accounted for using the number of high-frequency screen 61.5%, compared with last year have more greatly enhanced. One QGZS-G4 Ⅱ high-frequency shale shaker for the newly introduced, are used in good condition.

In 13 oil wells, 5 wells teams using the NCS-300 × 2-type Desander, two wells teams using ZCSQ-250×2-type Desander, six wells teams using the ZQJ-250 ×2-type Desander; accounting for the use of the number of 38.46% and 15.39%, 46.15%. Compared to last year, not the magnitude of changes, only to add two new Desander use.

In 13 oil wells a total of 12 teams use the SB-200 wells electric sand pump, a well teams using the SB-6″×8″ electric sand pump. Compared with last year, out of the belt transmission-type sand pump at the same time, the introduction of a new type of mechanical seal type sand pump.

After many years of practical use and continuous upgrading of the decanter centrifuge has been raised from a variety of models of multiple manufacturers into a relatively neat two manufacturers of the three models (which LW450×1000-NJ-type centrifuge at the end of March 2003 to replace eliminated); separation factor reached 800 or more, speed at 1800r/min above are more capable in  separating Sand, but also  facilitate equipment maintenance and management.
