Recently, the self‑developed rotary‑disc oil skimmer from Qingdao Huahai Environmental Protection completed on‑site water‑immersion testing and project acceptance at a southern river project site. Its operational performance far exceeded the customer’s expectations. The partner immediately confirmed renewal of the original contract and placed an additional purchase order for new‑batch equipment, recognizing Huahai Environmental Protection’s technical strength through tangible procurement.
In day‑to‑day work, Comrade Liu Guoqiang from the Sales, Installation and Service Department consistently upholds the work ethos of loving his post and treating the company as his own home. He earnestly fulfills his duties and completes all assigned tasks without evasion or slackness.
A batch of exquisitely manufactured Huahai Environmental‑Protection rubber dams have been fully assembled and shipped to Weihai. They will soon be put into local water‑governance, river‑regulation and ecological water‑storage projects. With robust product performance, they will help Weihai consolidate its water‑safety barriers and enhance its coastal ecological landscape.
How should air‑shield dams achieve anti‑freezing protection and safe operation under extreme freezing‑weather conditions?
Recently, all installation and commissioning work of a rubber dam project in Henan has been finished. After trial operation, the equipment maintains stable performance, and the project has successfully passed overall acceptance.
Rubber dams are widely used in river water storage, ecological management and flood control regulation projects. Long-term operation is prone to air and water leakage of dam bags, which impairs water storage efficiency and engineering safety. Drawing on years of operation and maintenance experience of rubber dam projects, Huahai Environmental Protection has compiled simple and efficient leakage inspection and on-site repair schemes in accordance with industry specifications, helping operation and maintenance units quickly address equipment faults.
