Title:
METHOD AND DEVICE FOR UNIFORMING CONVEYING FLOW RATE IN POSITIVE DISPLACEMENT PUMP
Document Type and Number:
Japanese Patent JP2010261461
Kind Code:
A
Abstract:
To achieve a uniform or constant conveying flow rate by a simple structural means with relatively economic outlay.
In a method for uniforming the conveying flow rate, the conveying flow rate of fluid in a conveyance pipe (5) is generated by at least two positive displacement pumps (1, 2) which are driven by drive motors with rotating shafts. The drive motors (6, 7) of the pumps are controlled so that the conveying flow rate gathered in the conveyance pipe (5) becomes uniform or constant.
