I. Heat conduction oil pump (including raw material pump and intermediate feed pump)
Features: 1: stable flow 2: general head is higher 3: some raw materials viscosity is larger or contain solid particles 4: pump inlet temperature is generally normal temperature, but some intermediate feed pump inlet temperature is also greater than 100 degrees 5: can not stop when working
Selection requirements: 1: general selection of high temperature gear oil pump 2: high head considered volume or high speed pump 3: standby pump
Two: reflux heat conduction pump (including the top, middle and bottom reflux pump) : 1: large flow range, low head 2: pump inlet temperature is not high, generally 30-90 degrees 3: high reliability requirements
Selection requirements: general selection of single stage centrifugal pump 2: pump reserve rate of 50%- 100%
