Studies on the Durability of Roller Pump (III)

On the Wear of Roller Rump Caused by Using Urine of Dairy Cow

Abstract

The wear of roller pump, using urine of dairy cow, was experimented and the following results were obtained.
(1) The total amount of wear of the clearance between rotor and side-wall, using urine of dairy cow, is about 1/10 compared with one caused by Bordeaux mixture (6-6). (cf. Fig. 3-4).
(2) The amount of wear of each part is remarkable with the higher delivery pressure
(3) The amount of wear of each part of pump was compared.
