Splash Liquid Density Tester

Abstract

The invention discloses a spraying liquid density tester which comprise an electric control box, a liquid adding cup, a magnetic drive pump, a pressure frequency converter, a fluid flow controller, a pressure controller, a guide pipe, liquid vapor spraying nozzles, a test model, a turntable, a motor and an outer cover, wherein the liquid adding cup is sequentially connected with the magnetic drive pump, the pressure frequency converter, the fluid flow controller and the pressure controller from left to right; the pressure controller is connected with one end of the guide pipe; the other end of the guide pipe is connected with the liquid vapor spraying nozzles; the liquid vapor spraying nozzles are arranged in the inner wall of the outer cover; the turntable is arranged at the bottom of the outer cover; the motor is arranged in the turntable; the test model is arranged on the turntable; the electric control box is connected with and is used for controlling the motion of the magnetic drive pump, the pressure controller, the liquid flow controller, the pressure controller and the motor; and a timer is arranged in the electrical control box. By adoption of the spraying liquid density tester, the test precision of protective clothing is improved, and a plurality of liquid vapor spraying nozzles are controlled at the same time by a programmable logic controller (PLC), so that synchronous action of the liquid vapor spraying nozzles is realized.

Description

technical field [0001] The invention relates to a measuring system, in particular to a splash liquid density tester. Background technique [0002] Labor protective clothing belongs to special labor protection products. As special-purpose clothing, it is mainly used for the protection of acid and alkali chemicals. How to test that the protective clothing can meet the national standard requires a professional tester for measurement. Ordinary testers mainly have the following shortcomings: [0003] 1. It is impossible to accurately control the flow rate of the sprayed liquid at the nozzle, especially for the tester with multiple liquid nozzles, it cannot meet the national standard requirement that the flow rate of each flow port is 1.14L / min, and the nozzle injection cannot be synchronized, precise; [0004] 2. Ordinary water pumps cannot meet the national standard of 300kpa for liquid pressure, and achieve small flow and high pressure; [0005] 3. The liquid nozzle during t...

Problems solved by technology

[0003] 1. It is impossible to accurately control the flow rate of the sprayed liquid at the nozzle, especially for the tester with multiple liquid nozzles, it cannot meet the national standard requirement that the flow rate of each flow port is 1.14L / min, and the nozzle injection cannot be synchronized, precise;

[0004] 2. Ordinary water pumps cannot meet the national standard of 300kpa for liquid pressure, and achieve small flow and high pressure;

[0005] 3. The liquid nozzle during the test cannot achieve a small flow rate and a long spray distance;

[0006] 4. The accuracy of the test time is poor, and the time difference from when the flow enters the pipeline to when it is sprayed is uncertain
