  Introduction to Centralized Lubrication and Oil Supply Systems

  What is a centralized lubrication supply system? A centralized lubrication system supplies moving or rotating machine components with the right quantity of lubricant at the right time. Lubricant travels from the supply unit through tubing to one or more lubrication points at set intervals. A central···

  Weidoya Recommendations for Using Machine Tool Pumps

  Precautions for use. Use a large-capacity tank wherever possible, with a capacity greater than 3 times the pump flow per minute. A small tank can cause fluid temperature rise and foaming, leading to noise and reduced pump performance. When installing the pump, maintain a clearance of at least 20–30 ···

  How to Calculate Head Loss in Centrifugal Pump Piping

  Method for calculating pipeline head loss. Accurately calculating head loss, or pressure loss, in centrifugal-pump piping is complex. Actual piping losses are often greater than expected and must always be included in the design. Head loss can be estimated using the Darcy equation, Moody chart, Cole···
