Drilling Fluid Desilter Usage & Application Scope As a solids control equipment of the third stage in drilling operation, desilter is used to remove solid particles of 20-40 µm in drilling liquid. The desilter of this type that has been reformed many times on the applications for years is reliable in technical performance and provides very good treatment results. Its water cyclone is of long service life and stable performance. It is applicable to various kinds of drills in the oilfields. The inlet and outlet of water cyclone can be connected very quickly, which is convenient for replacement and maintenance. Mechanics & Working Principle ZQJ10×12 silt cleaner are completed with 100mm polyurethane hydrocyclones, mud trough, manifold, motor, shale shaker, base and all necessary connections(as showed in Fig.1). The upper part of hydrocyclone is cylindrical with a tangential suction tube and a overflow tube in center. The lower part of hydrocyclone is cone with bottom silt discharge tube. The upper part and lower part are connected by hoop. The shale shake consists of basket, screen, springs and motor. The basket is mounted on base through four spiral springs. The screen is fixed to the basket with hook strip. The motor has the basket vibrate to separate drilling cuttings. Working Principle of ZQJ100×12 Desliter: When passing through the feed manifold, the pressured drilling fluid flow into the hydrocyclone in the direction of a tangent and spirally revolve downwards with high-speed. The drilling fluid bleed into mud tank through overflow gate and the solid in the mud is cut into the underflow that is drained to shaker screen due to the centrifugal generated by revolution.
