Calculation of Vacuum Pump Sucking Rate in Fishing Suction Equipment of Trawler

Abstract

Sucking rate is an important parameter for the design of vacuum pump, in order to obtain the accurate sucking value. Above all, sucking process of vacuum-pump is analyzed in fishing suction equipment, and then by means of Boyle-Malot’s law, a new equation is deduced, and a new method is improved after analyzing calculation formulas about sucking rate of vacuum-pump at the present time, this paper provides basis for selecting and design vacuum-pump in fishing suction equipment. After using the new formula to calculate the sucking rate, the damage rate of fish is greatly reduced in fishing suction.
