The Balanced Elliptical Motion Shaker developed produced by KOSUN has obvious advantages.

The Balanced Elliptical Motion Shaker developed produced by KOSUN has obvious advantages in dealing with high-viscosity drilling fluid. In this case, the large particles in drilling fluid can be effectively removed through the balanced elliptical motion shaker track, and the relatively mild vibration intensity can effectively reduce the consumption of the shaker.

Balanced Elliptical Motion Shaker is the fourth generation of new mud shaker. In the past mud shale shaker mainly used linear shaker, but now more and more drilling companies choose balanced elliptical motion shaker.

With the development of drilling technology, drilling depth is getting deeper and deeper, and the requirement of mud is becoming more and more strict. Some complex geological conditions under the ordinary mud vibration screen cannot meet the requirements of use. And the performance of ordinary drilling vibration screen is not very stable, the effect of drilling vibration screen treatment will be different according to the drilling address and cannot adapt, often there will be some running slurry or “horseshoe effect”. The appearance of balanced elliptical motion shaker has solved these problems.

Advantages of Balanced Elliptical Motion Shaker:

1. The handling capacity increases by 25%-30% compared with the linear vibrating screen;

2. Can adapt to a variety of geological conditions drilling mud recovery and purification;

3. Excitation force can be adjusted;

4. Linear vibration type has the advantages of translational elliptical vibration screen;

5. Balanced elliptic trajectory can effectively reduce the blocking phenomenon of sieve holes and ensure the sieve penetration rate;

6. Help to improve the cuttings transportation speed in viscous drilling fluid and prevent paste screen;

7. Can handle high specific gravity and high viscosity drilling fluid;

8. Longer screen life;

9. Drier cuttings;

10. Quick tensioning system, easy to replace screen.

Dry sieve is used to recycle liquid drilling fluid shale shaker in the well site.

Dry sieve is used to recycle liquid drilling fluid shale shaker in the well site, dry vibrating screen or dry sieve is a kind of linear vibrating screen, in the process of drilling waste management is mainly used for recycling the main vibrating screen and hydrocyclone discharge of drilling cuttings adsorption in liquid phase, the recycling of liquid phase method is especially suitable for oil-based mud, can effectively reduce the waste mud.

Compared with the mainstream drilling fluid vibrating screen, the dry sieve mesh used in the drilling fluid drying screen will be larger. As the cuttings treated by the drying screen are relatively dry, high-frequency vibration motor is generally used as the power source for drying. This allows the recovery of drilling fluid through the screen slowly, coupled with strong vibration force, can maximize the recovery of drilling cuttings in the liquid phase.

Functions of dry sieve treatment system:

1. Reduce the liquid content in cuttings and recover valuable drilling fluid, thus reducing the cost of drilling fluid;

2. Reduce the total discharge of mud cuttings, thus reducing the waste slurry to be treated, so as to meet the requirements of environmental protection.

Application fields of dry sieve treatment system:

1. Dry cuttings for drilling mud of various types, such as oil-base mud, water-base mud and composite base mud;

2. River dredging;

3. Environmental protection solid-liquid separation

4. Piling work;

5. Shield engineering.

Construction piling slurry separation equipment -DC series environmental protection horizontal screw settling centrifuge.

Construction piling slurry separation equipmentDC series environmental protection horizontal screw settling centrifuge.

Its working principle is to be processed after the sludge into the centrifuge, through the solid – liquid ratio, and rely on centrifugal field to expand the thousands of times, the sludge was settling in under the action of centrifugal force, be clarified sewage by clarifying liquid discharge pipe, dewatered sludge continuously from the host slag discharge mouth, again by shaftless screw conveyor directly transferred to the designated place or loading outbound, finally realizes the function of the separation of mud.

Based on the design principle of resource consumption minimization and manufacturing principle, various specially designed centrifuges have been widely used in environmental protection and industrial production fields.

KOSUN provide quality products and services to various industry users, not only high quality products, more importantly, KOSUN with rich experience dedicated to provide customers with a full range of customized solutions, from the design, selection and installation of horizontal screw centrifuge, to the special field of the whole set of equipment construction projects.

Maintenance of main bearing of construction piling separation equipment:

1. Lubricate the main bearing before starting the centrifuge or during the operation of 8 hours;

2. Lubricate once a day. The amount of grease used is strictly forbidden to exceed the standard;

3. If the centrifuge is out of service for a certain period of time every week, the main bearing should be lubricated before starting next time.

4. If the centrifuge is out of service for more than two weeks, the main bearing must be lubricated every two weeks.

Structure features of KOSUN vacuum degasser

During drilling operations, the gas carried by drilling fluid from the well can affect mud performance and safety, and also affect the service life of some equipment. Therefore, it is necessary to install a vacuum degasser to remove the gas concentration in the mud.

Structure features of KOSUN vacuum degasser:

1. Use vacuum pump to pump mud into the vacuum tank, and use it to make gas out of the vacuum tank, vacuum pump plays two different roles here;

2. Water ring vacuum pump is always in isothermal state in the working process, suitable for the suction of inflammable and explosive gases, with reliable safety performance;

3. The mud shoots to the four walls at high speed through the window of the rotor. The bubbles in the mud are completely broken and the degassing effect is good;

4. Main motor bias, lower machine center;

5. Adopt belt transmission to avoid complication of deceleration mechanism;

6. The use of liquid-gas separator will not cause water and gas to be discharged at the same time, so that the exhaust pipe is always unblocked.In addition, it can supply water to vacuum pump circularly, saving water.

7. The suction pipe is inserted into the slurry tank, and can be used as a high-power agitator when the slurry has no gas invasion.
