The centrifugal pump should meet the following performance test requirements:
1) While doing performance test, the tested centrifugal pump should mount bearing and sealing as specified in the order.
2) If approved by the buyer, in order to not damage the sealing appointed on the order, or the test fluids is incompatible with original sealing, the pump can be test with replacement sealing.
In the whole markets, centrifuge or even decanter centrifuge has been used in most fields. There are also mutual types or styles of decanter centrifuge in different fields. We just take oil drilling industry as an example; there are RFD decanter centrifuge, VFD decanter centrifuge, Disc centrifuge, hydraulic centrifuge, etc. Today KOSUN want to share some necessary tips on safe operation of decanter centrifuge.
There are a variety of different centrifuges depending on the specific need of your business. These include decanter, tubular, basket, peeler, pusher, and disc centrifuges.
Decanter centrifuge is widely used to separate (dewater) solid materials from liquids in solids control system when they are mixed together in mud. Meanwhile decanter centrifuge is also applied in many industries such as:
1. Solids separation (oil well drilling, refining, de-watering)
In the solids control system, there are usually several kinds of main equipment, including mud tank, shale shaker, vacuum degasser, desander, desilter, drilling fluid decanter centrifuge. Shale shaker is used to separate the big solids with diameter above 75μm, and 45~74μm for desander, and 15~44μm for desilter. Sometimes desander & desilter are combined as high efficient mud cleaner.
Drilling fluid mud gun is used to provide supplemental or primary mixing in mud tank depending on the number being used and the pit size. They are best used in the drilling fluids circulation mud tank corners to keep solids from settling with a drilling fluid mud agitator placed in the tank center.
The decanter centrifuge works on a principle of heavy solids settling , with the “ G “ force number by centrifugal force , the solids particle will be settling down and discharge and fluids content over flow to the other end to reach fine solids separation application . You can look at the centrifuge bowl to understand the principle of decanter centrifuge.
Mud Gun is designed and manufactured for different drilling mud solids control system, has such three types as low pressure, medium pressure and high pressure, is mainly matched to centrifugal pump and mud pump, and also can match shear pump. It is very special equipment to clean the wall tube and prevent mud sediment in the mud tank.
You know, decanter centrifuge is used for recovery barite to remove small solid particles, reduce the mud solid content, to ensure the performance of the drilling fluid. And drilling fluid centrifuge has high purification efficiency, convenient adjustment and easy maintenance.
During normal operation, due to various characteristics of the material,shale shaker will be blocking network in variety of different forms.The main breakdown reasons of blocking network as follows:
1. contains a large number of particles near the point of separation;
2.a higher moisture content of materials;
3.spherical particles or materials on the sieve with multiple points of contact;
4.static electricity can occur;
