Abstract

The invention discloses a diesel nozzle shear stability tester, which comprises a bottom plate. A plurality of universal wheels are uniformly installed on the bottom wall of the bottom plate; a driving motor is fixedly installed on the top wall of the bottom plate; a double-piston type injection pump is fixedly connected to a driving end of the driving motor; a pump speed adjusting screw and a pump exhaust screw are fixedly installed on the outer wall of the double-piston type injection pump; a stroke type counter is connected to the double-piston type injection pump; an installation frame isfixedly installed on the top wall of the bottom plate; a nozzle and an atomizing chamber are fixedly installed on the outer wall of the top end of the installation frame; an atomizing chamber outlet and an evacuation tube are connected at the bottom end of the atomizing chamber; and a backflow pipeline for excess liquid is connected to the nozzle. The diesel nozzle shear stability tester in the invention adopts a first sealing plate and a second sealing plate to tightly connect the atomizing chamber and a cooling device; a sealing plug is used for connecting the cooling device and a liquid storing groove, thereby improving the sealing performance of the diesel nozzle shear stability tester and improving the test accuracy.

Description

technical field [0001] The invention relates to the technical field of petroleum, in particular to a diesel nozzle shear stability tester. Background technique [0002] When the polymer-containing oil passes through the diesel nozzle of the diesel nozzle shear stability tester at a certain shear rate, the polymer molecules with poor shear stability are depolymerized and the kinematic viscosity of the sample is reduced. The shear stability of the polymer-containing oil is measured by the percent decrease in the initial 100°C kinematic viscosity of the sample. [0003] Most of the existing cooling devices used in the diesel nozzle shear stability tester are poorly connected to the atomization chamber and the connection between the cooling device and the liquid storage tank. Therefore, air is easy to enter the sample and form air bubbles, thereby causing experimental errors. Improve this. Contents of the invention [0004] The purpose of the present invention is to solve th...
