The hydraulic press is a mechanical device used for the stamping of sheet metal. Compared with the traditional mechanical press, the hydraulic press has the advantages of simple operation, fast speed and adjustable stroke of the press. However, the hydraulic press will produce certain pollution emissions during operation, including leakage of hydraulic oil, waste oil emissions, exhaust gas emissions, etc. This paper will introduce the pollution discharge of hydraulic press in detail, and put forward the corresponding treatment measures.
Firstly, the leakage of hydraulic oil is one of the main problems in the pollution emission of hydraulic press. The hydraulic oil used in the hydraulic system of the hydraulic press is often subjected to greater pressure and friction during operation, which is easy to cause wear and leakage of seals. Hydraulic oil leakage will not only cause waste of resources, but also cause pollution to the environment. Leaking hydraulic oil can contaminate surrounding air, soil and water sources, posing potential risks to the environment and human health.
Secondly, the discharge of waste oil from hydraulic presses is also a big problem. The waste oil mainly comes from the hydraulic system of the hydraulic press. After a long time of use, the hydraulic oil will lose its original performance due to pollution and need to be replaced. However, the waste hydraulic oil without treatment will cause pollution to the environment, but also caused a waste of resources. Waste oil often contains harmful substances, such as heavy metals, polycyclic aromatic hydrocarbons, etc., which have great harm to the environment and human health.
In addition, the hydraulic press will also produce exhaust emissions. The exhaust gas mainly comes from the press's compressed air system and hydraulic system. The compressed air system is usually used to drive the working stroke and auxiliary equipment of the punch, and when the compressed air enters the punch and is pressed, it will produce exhaust gas due to friction and compression. Leakage in the hydraulic system can also lead to exhaust gas production. The waste gas may contain some harmful substances and combustible gases, which pose potential threats to the environment and human health.
Aiming at the problem of pollution discharge of hydraulic press, a series of control measures can be taken. First of all, strengthen the maintenance and replacement of hydraulic system seals, regularly check and repair leakage problems, and reduce the leakage of hydraulic oil. Secondly, the waste oil collection and treatment system should be established, and the waste oil should be classified, collected and transported in accordance with relevant regulations, and treated by professional treatment equipment to reduce the emission of waste oil. In addition, the hydraulic system and compressed air system of the press are optimized to improve the sealing and efficiency of the system and reduce the generation and emission of exhaust gas. At the same time, strengthen the collection and treatment of the exhaust gas during the operation of the oil press to reduce the pollution of the exhaust gas to the environment.
To sum up, the pollution emission of the hydraulic press mainly includes the leakage of hydraulic oil, the discharge of waste oil and the emission of exhaust gas. To solve these problems, pollution emission can be effectively reduced by strengthening equipment maintenance, establishing waste oil treatment system and optimizing system design. These initiatives contribute both to environmental protection and to the health and safety of staff.
