The common problems of mud gun in solid control system are those as the followings. One of the fault phenomenon is the pressure obviously deficiency. The pump pressure deficiency will cause that problem. So you should inspect the situation of the pump. Opening too much mud gun in solid control system may make the pressure deficient, so you should try to decrease the quantity of the opening mud guns. The violent wear and tear of the sprayers will cause the problem as well. So you have to check the sprayers and change the arrased ones.
Another common problem of the mud gun in solid control system is the drilling fluid leakage which may dangerous if the drilling fluid is lit by fire. The unsealing oil seal or the unsealing valve may cause the drilling fluid leakage of mud gun in solid control system. So you have to change the oil seal or change the valve to ensure the safety. The not enough essence of mud gun in solid control system is also a common problem. It may be the blocked sprayer cause the problem so you should unchoke the sprayer. Last but not least, the not flexibility of the rotation is another problem. The centering sleeve block or the rolling bearing issue may cause the problem. What you have to do is unchoking the centering sleeve or adding lubricant to the rolling bearing. If that does not work, you should aspect the rolling bearing.
PS: stack sizer is the general term of the theory, control equipment or skills of removing the harmful solid phase and keep useful solid phase. The content of solid phase is an important reference data of mud. And the modern mud technology pays more attention to the solid phase content of the cement to control the solid phase content to 4% or even lower. The control of the solid content is important to the maintenance of the mud gun in solid control system. As the control of the solid phase has to eliminate the rock wastes, low-quality clay, colloid granular barite and other waste rock mixed in. This method can highlight the working speed of stack sizer and longer the using time of the stack sizer. Also, it can make the using time of the driller longer and avoid abrasion of the driller and the other equipment. To a great extent, the control of the solid phase will prevent the happening of the accidents and damaging the oil layer. There are two ways to control the solid phase, one is chemical method and the other is mechanical mean.
These are the problems of mud gun in solid control system that may happen during the oil rig. And we hope you can get the important information that you need and solve your own problems.
