PURPOSE:To improve working efficiency of a rotary pump, by discharging reaction product and sludge through an oil discharge pipe to the outside of the pump to prevent accumulation of the reaction product. CONSTITUTION:With an air suction port 8 of an oil discharge pipe 7 closed with a needle 11, a quantity of the air sucked is reduced, and this increases discharge pressure of the oil in a rotary pump 1. As a result, a large quantity of the oil is discharged, and reaction product and sludge are also well discharged following said discharge. In this case, the oil contains quantities of the reaction product and sludge, and thereby they must be removed on the way without returning them to an oil tank. |
