GN Centrifugal Pump used in Drilling Fluids Recycling

Here in this article, the actual centrifugal pump we referring to is a device designed along with engineered to handle abrasive, viscous and corrosive fluids inside drilling fluid or professional slurry applications. With the functionality matched by exceptional overall performance, high volume, high temperature features, long service life, easy for upkeep, overall economy and higher savings. Currently, this type pump motor is widely used in operation in land-based and offshore going rigs around the world.
In regards to the going industry, the centrifugal pump could be used to transfer the particular drilling fluids, mixing the harmful chemicals into the fluids. Thus this always be equipped in the providing pump system for giving drilling mud to de-sander and de-silter and fly mud mixer unit for a mixing pump. Besides, it is also used as trip water pump used to feed the going fluids into deep straight down well when changing the going pipe and supercharging send for rig high pressure magnetic pump.
GN Centrifugal pump Advantages are as listed below:
1 . The much plumper housing is for extra power and extended service life. Often the concentric design housing removes turbulence and cavitations inside pump, and it also reduces the actual radial load on the bearings.
2 . The open vane impeller is designed to reduce désordre, lower radial and press loads, and provides a simple flow of fluid with the pump.
3. The tube shaft with a large height ensures the heavy duty effectiveness with minimal shaft defection. The shaft sleeve in addition to mechanical seal can be substituted without removing the canal from the pump.
4. GN centrifugal pump adopts kinetic type seal which is manufactured from the best material so far worldwide. This type seal delivers excellent performance with superior style. Our seal distributes push torque over 10 commute tabs, which greatly minimizes stress on the outer retainer-like.

Drilling Mud Five-stage Solids Control

You might possibly have heard desilter 5-stage solids control plan. Possessing said that, what is specifically the desilter 5-stage solids deal with system? Proper here, Guanneng Business can clarify this for you.
Initial Stage of Solids Manage Strategy
desilter is broadly usually known as a solids handle equipments applied in drilling projects. It is a fairly basic gear that could separate the drilling cutting more than fundamentally, the solids manage and purification come about within the related time. Just as its name implies, solids manage is separate the solids within the fluids, even though the drilling cutting in conjunction with other large size impurities becoming separated, the drilling mud is purified.
Second Stage of Solids Control Strategy
A vacuum degasser might be utilised as the second stage purification gear. Within this stage, there’s no solids separated inside the drilling mud, just the invasive air is removed. Why do we’ve to take away the air in the drilling mud? Invaded air can lessen the particular gravity in the mud and make the centrifugal pump work with low efficiency.
Third Stage of Solids Handle Approach,the releated pls refer to http://mudcleaner.wordpress.com/2014/05/04/gn-desilter-procedure-method/
Quickly just after becoming treated by vacuum degasser, drilling mud is fed into desander by centrifugal pump. The principle parts of a desander will likely be the hydrocyclones. desilter can take away the sturdy Control System
Determined by the exact same functioning Handle Method
You are going to see this desilter equipment in significant mud program for oil & gas drilling. Decanting centrifuge is the leading role in this stage. By centrifugal sedimentation principle, it delivers high fluid-recovery rates and efficient solids manage to significantly cut down the costs of fluids concoction and disposal.
Guanneng Enterprise has been providing a complete line of solids manage gear for the oilfield industry and the environmental industry for over 25 years. Guanneng Business can provide customers with several series as oil & gas drilling solids handle gear, centrifuges, drilling waste management equipment,desilter, etc.

operate the cuttings dryer system after long time off status

If we operate the cuttings dryer system after long time off status, we need to inspect motor rotary unit on insulation. Use 500V Ω gauge, get resistance is not larger than 0.5MSZ, we can run the shaker

Notice: ① If the motor doesn’t run at all, we must shut off the power immediately to avoid motor broken
② After starting motor, to inspect, whether this is any problem. If there is any break off or uncommon noise. If two motors are not running in-phase we need to stop the motors and get rid of problems then turn it on again for operation
③ When motor is under cold status, should not be started 5 times continuously; when motor is turned off under hot status, the restart can not be over 3 times continuously
Shaker screen maintenance
① Before every shut off, the shaker should run without any medium for 5-10 minutes, at the same time, use clean water to flush screen clean
② Every time finish operation, the shaker frame and screen should be flushed by water (summer) or steam (winter), there should be not much sediment on shaker frame and shaker screen. Especially when the drilling mud has large viscosity and high density or screen is finer than 60 mesh. Otherwise, the particles and fine sand on screen will block screen hole, when we start shale shaker, it will decrease filtration result and lead drilling mud flow away, lose much unnecessary cost.
cuttings dryer maintenance
Electric control cabinet is explosion proof magnetic starter, the electric principle is as fig VI, if there is any trouble we must shut off the power, and repaired by electrician or specific person
