Jet mud mixer extensively used in solids control

The jet mud mixer is extensively utilized in business and also city sewage therapy and the aerated grit chamber. It also is utilized for modest sewage treatment, industrial wastewater remedy and aeration pond. Meanwhile, the jet mud mixer is also applicable to the sewage treatment plant together with industrial process about mixing with liquid suspensions.

Jet mud mixer

But do you know what need you to note while installing the jet mud mixer in drilling mud system?

1. General requirements mixing hopper capacity shall not be less than 150m3/h. For the larger tank and great pump motor power, we can also use the mixing hopper with 300m3/h capacity.
In order to ensure the required well pressure, suggest that each drilling crew should equipped with a spare set of mixing hoppers, in most cases spare hoppers used overlap mode.
2. The return pressure of outlet pipe needed moderate, overlarge return pressure will reduce the treating capacity of mixed hopper.
3. The gap between nozzle and venturi tube must be suitable, when reach optimum efficiency, the gap is 32~90mm, usually don’t more than 90 mm, otherwise the feed speed of barite will be significantly reduced.
4. Another important consideration of install equipment is the drilling fluid required lifted height. If discharge needed to enter into different deck tank or a taunt tank and hopper, mix rate will be decreased. When the height from 1.83m to 3.66m, barite adding rate will be reduced to 17%. If the increased demand is very high, the pump capacity is insufficient, mixed ability will be greatly reduced.

Solids control is so indispensable in drilling that we can’ t work in drilling without it . As one of the professional manufacturers in China solid control, KOSUN provides all the solids control equipment, such as shale shaker, decanter centrifuge,vacuum degasser, etc. Except specializing in designing & manufacturing jet mud mixer, KOSUN can also manufacture a whole solids control system for oil& gas drilling as the requirements of the customers.

Requirement of high effective mud centrifuge pump

After the centrifugal pump started, the pump shaft drive impeller together to do high speed rotation, forced beforehand filling between the blades liquid rotation, under the function of inertia centrifugal, liquid does a radial motion from the impeller center to peripheral. Liquid won energy in the process of flow to impeller movement, static pressure energy increases, velocity increased.

Oilfield drilling solids control spot

To work effectively, drilling fluids 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
3) In any stage of the centrifugal pump performance test, it is not allowed any leakage over the rate of Standard ISO21049, or over the rate appointed between vendor and buyer.
If there is any leakage over the appointed rate during performance test, the centrifugal pump manufacturer should disassembly the sealing for maintenance. While open or disassembly the pump sealing, the operator should again do air test to the sealing.
While the centrifugal pump use water as performance test fluids, the fluids sealing suitable for water have no sign for leakage. It should double check the sealing performance per standard ISO21049:2004, and insure it is accordance with the zero visibility leakage standard.
4) If there was leakage, it should be test again after repairing the centrifugal pump sealing. And to insure the centrifugal pump have a good performance for sealing.
5) The lubrication oil pressure, temperature, and viscosity should be under the scope of the user manual offered to the buyer.
6) Regarding bearing request for pure oil mist lubrication system, it should be lubricated with suitable oil type.
7) All sealing parts and connection parts of the centrifuge pump should be checked careful to avoid leakage.
8) All alarming system, protection system and control system regarding centrifugal pump performance test should be checked, and adjust per test requirement.
Passing the above tests, the centrifugal pump is qualified for delivery. Just because of this, KOSUN has always been enjoying a good reputation in the field of drilling solids control for years.

In China solids control industry, KOSUN supplies other solids control equipment including, linear motion shale shaker, shale shaker screen, desander, desilter, vacuum degasser, centrifugal pump, submersible slurry pump, shear pump, mud agitator, mud gun, drilling fluid mud cleaner, jet mud mixer, mud tank, diesel tank, water tank, complete drilling mud solids control system, etc.
