It is the most normal size decanter centrifuge used for both solids control system and drilling waste management system with its reliable performance and cost-effective price.

2) Big bowl big capacity decanter centrifuge GNLW553-VFD, variable speed control, 22 inch big bowl size

As more and more customers prefer solids control systems only with shale shaker, it request s high standard of solids control decanter centrifuge. GNLW553-VFD is an ideal model to used together with solids control shale shaker.

Furthermore, GNLW553-VFD big bowl centrifuge is also widely used for drilling waste management system.

3) Drilling waste vertical cuttings dryer   

GN patent design vertical cuttings dryer can be used to treat OBM, SBM as well as WBM. Customer can use the same system to treat most kind of mud.

All above equipment, GN has stock available in Houston, U.S.A. GN Solids America is a separated brand registered in Houston TX in year 2013. It is the first U.S.A based Solids Control manufacturer from China. GN Solids America offers sales service and rental service in America. You can contact GN Solids America for more information.

 

The function and principle of Oil water filter

Oil water filter, it is mainly used to treat the contaminated oil, such as cooling system oil in drilling waste vertical cuttings dryer. Its function is filtration, purification, recovery or enhance the attributes of oil itself. The treatment process is including oil cleanliness, moisture content, gas content, acid value, viscosity, flash point, the insulation strength, color and so on. Oil water filter can effectively remove impurities in oil to guarantee safe operation of the equipment.

Application scope of Oil water filter

Oil water filter is mainly used in mining industry, metallurgy, petroleum field (drilling mud cleaning system), railway, machinery, chemical, textile, cement, power, instrumentation and other industries. It has big effect on the purification and recovery of variety of industry waste lubrication oil. Oil water filter can extend extend the maintenance cycle and service life of equipment, and reduce the production cost.

Furthermore, oil water filter can effectively remove oil pollutants such as: water, water soluble acid, alkali and mechanical impurities, improve the kinematic viscosity, flash point of oil, emulsification. To make oil quickly returned to the desired properties, close to or reach the national standard of the corresponding new oil.

Oil water filter for liquid mud plant base oil tank

Oil base mud is a normal kind of drilling mud for deeper oil and gas drilling. Diesel oil is used as base oil. Oil water filter is used before based oil tank, after treatment, the oil will be transferred to base oil tank through oil pump.

Beside oil water filter, there are other equipment are necessary for liquid mud plant

1) Mud agitator: it is equipped in each tank compartment to enable the mud moveable all the time, to avoid it from settle down.

2) Mud mixing system: for continue mud prepare

3) Huge capacity mud tanks

4) Electrical control system and lighting system for the whole system

5) Rain shade to protect the whole system from strong sunshine or rain.

Shale shaker is the first stage solids control equipment in drilling rig mud system. It is the necessary equipment for mud solids control. According to the motion type generated by vibrating motor, there are linear motion shale shaker and balanced elliptical motion shale shaker. While linear motion shale shaker is more widely used as it can suits a wider range application and it is workable even with big handling capacity.

Rubber sealing for linear motion shale shaker in drilling mud system

Rubber sealing is an essential part for shale shaker performance. It is the rubber used between shale shaker deck and shale shaker screen.

1) The rubber can seal the shaker deck and shaker screen better. It can prevent the shale shaker leakage.

2) The rubber sealing can extend shaker screen lifetime and protection shaker deck from worn out. The shaker deck and shaker screen frame are both made from metal. If there is no rubber between them, the metal touched each other directly and vibrating under high G force. It will generate big noise and the screen and shaker deck will be damaged soon.

Other features affect linear motion shale shaker lifetime and performance

Besides rubber sealing, there are other features that will affect the shale shaker lifetime. It includes but not limited to following:

1) The materials of shaker deck. Stainless steel can surely stand longer than carbon steel

2) Suitable shaker deck angle can enable the mud move forward shaker deck more fluently and get a longer lifetime of the shaker screen.

3) Suitable G force. If the G force is too small. The mud cannot separate well and then overflowed. It is a waste. If the G force too big, one side, it may damage the drill mud contend, another side, big G force will shorten shaker screen lifetime.  

4) Reliable brand vibrating motor and strong enough design for shaker wall

Applications of Explosion proof cable

In some job site condition, such as mining industry, oil and gas drilling field, or other flammable mixed gas environment, explosion proof cable is widely used. It can be used for the contacting of motors, control panels or the explosion proof control system. All these environments are with flammable and explosive gases. If the common cable be used, even a slight friction generated between the plug and the socket, or even subtle spark will be risk. So we have to use explosion-proof cable tray. It is professional and more reliable.

Features of Explosion proof cable

The same with normal cable, explosion proof cable has leakage protection. There is a small built-in leakage switch for explosion-proof cable. In case of leakage accident, the leakage protection switch will power off in 0.03 seconds. At the same time, in order to avoid sparks and electrostatic etc… to cause explosion dangerous situation, all of the configuration including  socket, plug, handle are aluminum, and after spray treatment; plug housing and rotary table adopts aluminum alloy, which is durable, safe and reliable.

Application scope of Explosion proof cable

1) Zone 0, Zone 1, Zone 2 Hazardous area

2) IIA, IIB, IIC class of T1 ~ T6 group explosive gas or steam environment;

3) combustible dust environment 20 zone, 21 zone, 22 zone;

4) Indoor, Outdoor (IP54, IP65)

Technical characteristics

1)The turntable and explosion-proof plug housing is made from casting aluminium alloy, surface is sprayed with PU;

2) With build in leakage protection, circuit breaker;

3) With ON OFF indicating on pin points, the grounding contact is longer than its main contact;

4) There are interlocking device on plug and socket. It can plug after power off;

Technical parameters of Explosion proof cable

1) The rated current: 16*2, 32*2

2) The rated voltage: AC220V/380V

3) Explosion-proof grade: Exd II BT4/T5/T6

4) Protection grade: IP54, IP65*
