XBSY RFD Decanter Centrifuge
The LW355 centrifuge is a high-speed one and is mainly used to remove fine particles of 2~5 µm in the drilling fluid. The LW450, LW520 and LW630 centrifuges are medium-speed ones and are mainly used to remove harmful solid-phase particles of 6~10 µm in the drilling fluid.
LW Series Decanter Centrifuge Advantages
The drum (core component) is made of SAF2205 duplex stainless steel by centrifugal casting process, and its performance is superior to conventional 304 and 316. All weld joints have undergone flaw detection and thermal treatment, and are provided with certificates of conformity or records for traceability.
The dynamic balance precision of the centrifuge is ≥ Class 2.5, which is superior to the requirement of the standard, so that the centrifuge can be operated smoothly and its service life is extended. The noise of the complete machine is < 85 dB, the vibration intensity is < 7.1 (load) and 4.5 (no-load). It is equipped with a mechanical and electrical dual overload protection device to ensure safe operation.
Long Service Life
The screw pusher and drum are of the most advanced, reliable and convenient wear-resistant treatment technology and structure in China. All bearings are original imported NSK/SKF bearings. The electric control box is made of electrical elements of famous brands such as Siemens and Schneider.
High Degree of Automation
It is equipped with a VFD explosive-proof control cabinet to achieve one-button automatic start and stop. The complete machine is equipped with bearing temperature sensor and vibration sensor, and is provided with alarms for main motor overload, differential overtorque, low differential speed, etc.
XBSY RFD Decanter Centrifuge Technical Parameters
The speed of the RFD centrifuge drum is constant and can be changed by replacing the drive pulley. The RFD centrifuge is easy to operate/maintain. Models with different drum speeds and treatment capacities can be used according to the size of the drilling machine and the actual demand.
