Centrifugal pump is a kind of newly developed pump matching to solids control equipment in petroleum, mine and drilling. It adopts axial suction structure and overflowing parts are wear-resistant cast iron. It is suitable for transporting corrosive drilling fluids containing suspended particles or other liquid mediums with similar properties. The parametric design of sand pump fully considers that the matching solids control equipment can work under the optimal working conditions, and its main features are high interchangeability of parts, little shaft seal leakage, reliable operation, long service life and convenient maintenance. Generally, in drilling fluid solids control system, centrifugal pump matched with other solids control equipment like desander,desilter, jet mud mixer.
Centrifugal Pump
Centrifugal pump should be in accordance with the conveying liquids to undertake choosing, and checked required performance, analysis suction, exhaust condition, whether it is intermittent operation or continuous operation, etc. Centrifugal pump usually should be in or close to manufacturer designed specific pressure and flow conditions operation.
How can we select and install centrifugal pump for solids control system?
① basic sizes, position, elevation should comply with the design requirements, the anchor bolts must be properly and accurately fixed in concrete foundation, the machine should not have missing parts, damaged or corrosion situation, etc.
② according to the pump transport medium characteristics, when necessary, should check the main parts, shaft seals and gasket materials.
③ pump level, right working shall conform to the provisions of the equipment technical documents, if without rules, should be consistent with existing national standards "mechanical equipment installation project construction and acceptance general specification" regulation,
④ all pipelines that connects with the pump body, pipe fittings installation and lubricant pipeline cleaning requirements shall be in compliance with relevant national standards regulations.
