Multi-sample continuous testing device for viscosity of solid propellant slurry

Abstract

The invention provides a multi-sample continuous testing device for viscosity of solid propellant slurry. The multi-sample continuous testing device is composed of a constant-temperature circulating water tank, a sample cup, a sample heat preservation barrel, a rotary viscometer, a rotor and a rotary disc. The sample heat preservation barrel is externally connected with the constant-temperature circulating water tank and circulating water is introduced into the sample heat preservation barrel; the sample cup is arranged in the sample heat preservation barrel; the sample heat preservation barrel is arranged on the rotary disc; the sample heat preservation barrel and the constant-temperature circulating water tank are used for preserving heat of the sample cup containing a sample; a cavity is formed in the sample heat preservation barrel; circulating water is introduced into the sample heat preservation barrel; the sample heat preservation barrel is externally connected with the constant-temperature circulating water tank; and a circulating water inlet is formed in the lower end of the outer wall of the sample heat preservation barrel. Compared with the prior art, the device has theadvantages of being novel in design, simple in structure, easy to operate, adjustable in temperature, convenient to clean, small in test data error, high in test efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of performance testing of composite solid propellants, in particular to a multi-sample continuous test device for the viscosity of solid propellant slurry. Background technique [0002] Composite solid propellant is the main component of solid motor, and its production is a relatively complicated process, which has gone through processes such as weighing, premixing, mixing, mandrel disposal, pouring, curing, demoulding and shaping. Among them, mixing, pouring and solidification are the process of reacting the liquid slurry mixed with various materials into a solid composite solid propellant. [0003] The rheological properties of the composite solid propellant slurry directly affect the mixing and pouring process of the composite solid propellant, and the process performance. For the composite solid propellant using the pouring molding process, the slurry must have the rheological properties to smoothly flo...
