Vacuum systems are a popular tool for many types of contractors on drilling field, especially for no dig drilling field, like HDD.  

There are three primary types of uses, each of which requires slightly different configurations and specifications.
1. Support HDD unit (transport drilling mud, expose utilities, etc.) Tank size should be large enough to hold drilling mud that can be hauled  off from rig site.
2. Hydroexcavation (use vacuum instead of trencher or excavator to dig hole or trench; use vacuum to expose utilities)
Tools to allow for using high pressure water or air to “dig” the hole are necessary.  Also need a tank large enough to hold the “spoils” created during the digging.


3. Water & sewer cleaning & maintenance (Use high pressure water to clean out sewer lines or vacuum to suck up water.)
Must generate enough water pressure to effectively clean the pipe.Must also have a large water tank (for use in the washing).

Other application of vacuum system

Vacuum pump is kind of transfer pump utilize high vacuum pressure to transfer drilling cuttings, dust, solids, etc… It is widely used together with drilling waste management system for un-landed drilling waste management. To transfer drilling cuttings for high G dryer shaker or vertical cuttings dryer. The vacuum system utilize good sealing to avoid any disposal drop to the ground for pollution. It can keep the jobsite clean.

China top solids control manufacturer: GN Solids Control, exported a complete set 1200GPM mud recycling equipments to middle east market for HDD drilling rig.

The system is customized for the customer. To further reduce the total cost of the tank, GN company offered complete equipment, and offer customer tank design drawing free of charge, customer build mud tanks locally. They are happy with the solution and the system used very well now.

Equipment for the 1200GPM mud recycling system:

1) 3 each Shale Shaker GNZS579

2) 1 Mud Cleaner with 3 each 10’’ desander cone and underflow shale shaker model GNZS594 (Desander cones only )

3) Jet mud mixer

4) Agitators

5) Centrifugal pump feeding for the desander cone

6) Mud tanks 1 each. W 3000 mm, H 230omm, L 12000 mm

Customer want tank size is  W 3000 mm, H 2300mm, L 12000 mm with center Partition , the I section for 3 Shale shakers with 2 Agitators,  II section for Mud Cleaner with 2 Agitators and the jet Mud Mixer. Centrifugal Pump Model SB8x6-12J for mud transfer  from Shale Shakers Section to Desander cones. 

Conveyor, also called screw propeller. It is the most important part of waste management decanter centrifuge. We can also see it as the core of decanter centrifuge.

For different conveyor speed, the separation performance is different. For different drilling fluids, the centrifuge conveyor should defer. Professional users know how to change for a suitable speed for a better performance.

GN variable speed centrifuge (VFD), conveyor speed can be changed during centrifuge running. Customer can change the conveyor speed per different drilling fluids type.

For GN decater centrifuge, main motor is connected directly with bowl. Back motor is connected with gearbox and then connect with centrifuge screw propeller. When change the frequency of the motor, customer can get the different conveyor speed.

GN engineer just came back from Middle Asia, They have made commission job for a GN500 GPM mud cleaning system for HDD rig.

This unit mud cleaning unit with capacity 500GPM. It is designed per customer specified requirement and GN professional engineering standard .

The 500GPM mud cleaning system for HDD rig is including 2 phase solids separation:

1) 1 unit mini cleaner with under shale shaker GNZS703 double deck model and 8 ea desilter cyclone.

2) 1 unit mixing hopper

3) 2 units centrifugal pump one for mud transferring to desilter cone while another one used as mixing pump.

4) 1 unit mud tank divided into 2 compartments for sand trap and mud mixing tank.

Strong practicability and cost saving always make GN mud cleaning unit satisfy the customer.
