FLUID PUMP EQUIPPED WITH TEMPERATURE ADJUSTOR WHICH KEEPS CONSTANT MASS FLOW-RATE

摘要

PURPOSE:To obtain the captioned pump which always keeps a constant mass flow-rate by keeping each temperature of the inflow fluid and a chamber always constant. CONSTITUTION:Solvent is introduced into a head 3 through a suction pipe 6 form a bottle 1 charged with fluid. The intermediate part of the suction pipe 6 is constituted of a thermal equillibrium coil 2, and the periphery of the thermal equillibrium coil 2 is enclosed by an aluminium block 4. With such constitution, the temperature of the solvent becomes constant during passing through the thermal equillibrium coil 2, and the mass flow-rate can be kept always constant.
