Problems solved by technology

[0009] The technical problem to be solved by the present invention is that the oil mist testing equipment or system introduced in the prior art only adopts the mechanical fogging method, which cannot effectively simulate the fogging method in the metal processing process, and therefore cannot accurately evaluate the oil mist characteristics of the machining fluid. Provide A new testing equipment for oil mist characteristics

Embodiment 1

[0029] according to figure 1The oil mist characteristic testing equipment in the center is used to test the oil mist characteristics of oil products under the coexistence of three fogging methods. The size of the spray chamber and the oil mist test chamber are the same, both are 40×40×50 cm. The included angle is 10°, the temperature in the spray chamber and the oil mist test chamber is 25°C, the pressure is 1MPa, the temperature of the heating plate is 150°C, and the oil sample used is N15 base oil with 0.5% oil mist suppression For the oil product after agent A, the injection volume of the spray port is 10 ml, and the characteristic values ​​of the oil mist are shown in Table 1.

Abstract

This invention relates to a device for characteristic test of oil mist, which mainly resolves the problem of evaluating exactly the characteristic of liquid oil mist. The invention resolves this problem effectively through the technical project of characteristic test of oil mist which comprise following steps: a, spouting the oil and air to revolving member from air injection nozzle in the spray chamber; b, forming fog by collided drops on the heating member; c, testing the characteristic of oil fog by using exiguous oil fog in the test cabinet. It is suitable for evaluating the oil fog characteristic of metalworking lubricant in laboratory.

Description

technical field [0001] The invention relates to an oil mist characteristic testing device. Background technique [0002] During metalworking, metalworking lubricants are required for effective lubrication, cooling and cleaning. Due to the process of pump circulation, spray, jet flow and high-speed rotating tool violent impact and high-temperature evaporation during the use of metal processing lubricants, a large amount of oil mist will be generated, and these oil mist will be suspended in the air as small particles. Among them, oil mist particles with a diameter of less than 5 microns can smoothly reach the alveoli of the human body along with the breathing process of the operator, and settle in the lungs, thereby causing harm to human health. Therefore, the oil mist control of metalworking lubricants has been closely watched by occupational safety and health management agencies around the world. The American Association of Governmental Industrial Hygienists (ACGIH) propos...
