Gland type suction sand hole seal power green manufacturing

Gland type suction power green manufacturing 2021 - sand holes on the seals 01 - 29 to reduce the large bridge steel members shore sand after secondary hot and coating process, welding and painting to avoid 'rework' cause environmental pollution, port group onshore heavy industry design and research institute, with environmental protection as the guide, joint changxing branch formed sand suction hole sealing subject research group, communicate with subsidiary in changxing docking, unreal, from the source to find a way to design, to achieve suction sand hole sealing process of 'zero discharge'. Large steel members chamber blasting has been completed, need to open suction sand hole on the legacy of the sand to clean up, upon the suction sand with the steel plate welding seal. Seal welding required in housing construction, the environment is bad, welds to flaw detection, and construction. At the same time, the welding process can destroy the surrounding paint, local area should be applied, paint the second construction. Research team has designed a bend type component seal, sealing, threaded pipe manhole cover seal of multiple solutions, finally determined the gland seal design. Verified by test, easy installation, good sealing effect, thoroughly solved the environmental pollution problem in the process of sand suction hole sealing, the results also won a silver medal of the companies' closing 'innovation and efficiency. Gland seal type suction sand hole design scheme has been formed to promote implementation of standard drawing, design personnel in the design phase communication with users, plan approval, the company actively, get their approval and support, to promote environmental improvement efforts. Lu Gong courtyard through to the environmental protection propaganda and education, improve employees' environmental protection consciousness, guide the designer to find problems and countermeasures, to create a good atmosphere of design in environmental protection. Encourages designers to proactive, continuous unreal, from the source to find a way to design, the concept of green design into product, promoting the development of port machinery products high quality. （ Source: Shanghai zhenhua group)
