Some problems with design of Model JL35-DZ drilling fluid centrifugal

Model JL35—DZ drilling fluid centrifugal is developed by applying frequency control, time delay control and automatic cleaning techniques. An investigation is made in some problems with the optimization of the centrifuge, including the planetary gear mechanism and safety device, lubricating condition of planetary gear sleeve and mechanism, feeding pump and frequency control mechanism, time delay and automatic cleaning devices. The key technique and advantages of the centrifuge are pointed out. The methods for calculating the diameter of safety pin, fit clearance between the sleeve and hole in the planetary gear, and the quantity of the lubricants filled in the gear mechanism are presented.
