Description

Device for rapidly testing oil stain on deep cooling fast line storage tank

Technical Field

The utility model relates to a grease test technical field, concretely relates to test device of cryrogenic fast line storage tank greasy dirt fast.

Background

The metal optical fiber laser cutting machine is applied to metal pipe materials and pipe material cutting such as sheet metal processing, stainless steel, galvanized sheet, carbon steel and the like, high temperature is generated by focusing high-energy laser through a lens, wherein nitrogen is used for cooling the lens. The deep cooling express storage tank is 1-5 m in volume³The gas supply mode has the advantages of reducing the frequency of gas replacement of the equipment, along with simple and safe operation. If oil stains exist in nitrogen or a cryogenic fast line storage tank, the lenses can be polluted in the blowing and cooling process, so that the lenses cannot be gathered, the energy of laser is reduced, and the thick plate is not cut.

At present, the deep cooling express line storage tank uses stainless steel or carbon steel in the processing and manufacturing process, oil stains exist in the post-treatment process, and the micro oil stains can not be observed through eyes. At present, the methods for testing the oil stain in the cryogenic fast line storage tank mainly comprise the following steps:

1. after the oil on the surface is extracted by the organic solvent, the oil is measured by an infrared oil analyzer, the quantification is accurate, but the operation is complex and the price is high.

2. The oil stain emits fluorescence under the irradiation of the ultraviolet lamp, and whether the oil stain exists can be judged by adopting the ultraviolet lamp to irradiate under a dark environment, so that the oil stain testing device has the defects of more interference factors and inaccurate testing.

The common defects of the two methods are that the existence condition of grease after gas passes through a cryogenic fast line cannot be tested, and when the gas passes through the gas, the grease can be taken out of a pipeline by the gas to reach a client for use, particularly the inside of a cryogenic fast line storage tank, and the test cannot be carried out by the methods.

In order to solve the common problem, the outlet of the deep cooling express line storage tank can be plugged by clean cloth at present, and whether oil stains exist on the clean cloth is observed after the large-flow gas is blown for 20min so as to judge whether oil exists in the deep cooling express line storage tank or in the gas, but the clean cloth can observe a large amount of oil residues and still cannot monitor trace oil.

In view of this, when the customer end uses the cryogenic fast line storage tank, it is found that the lens that the greasy dirt pollutes the customer end will produce the loss. It is therefore very necessary to find a method for testing oil contamination close to the use of the client.
