What are the requirements of the steel mooring buoy we often use in the sea? What should be paid attention to for the customized steel mooring buoy?
What is the 16-character management requirement for the visual navigation mark in the sea mark operation rules? Answer: mark position accurate, the light quality is normal, the coloring is bright, the structure is good when the new danger object threatens the ship to sail seriously, can use the radar transponder mark, its code is Morse signal is what? Answer: what a few aspects does D air standard collocation cloth design mainly include? A: including geographical location; Equipment and body structure; Light range and light properties; Type of logo; Equipment configuration department of transportation air quality management system documents including? Answer: include quality manual, procedure document, work instruction, and quality record. Fire detection, fire performance ≥B1, is a refractory material. Improper stacking of PVC anticorrosive tiles will cause material deformation. Can not save the trouble and pile up at will, the material with a long time stacking style and deformation. Some physical processes such as the physical dissolution of metal materials in certain liquid metals can also be classified as metal corrosion.
AIDS to navigation in inland rivers refer to visual, audio and radio AIDS to navigation set up to help ships and facilitate navigation, referred to as AIDS to navigation in inland rivers. By reasonably distributing navigation marks for inland rivers, the direction, limits, and obstacles of inland waterways can be marked, and the information of relevant navigation channels can be revealed, so as to indicate an economic navigation channel for ships. Navigation marks on inland rivers are classified into three categories: navigation, danger, and signal. Logo shape, coloring and lighting properties are unified according to the role of the shore (or background). Navigation beacon is an important navigational aid for ships sailing in inland rivers. The main function of navigation beacon in the inland river is to mark the direction, limit and obstacle of the inland river channel, reveal the information of relevant navigation channels, and point out and economical navigation channel for ships.
PVC tile and resin tile is the current unit and personal love a kind of building materials, but a lot of people do not understand the difference between them, some people think that PVC tile is resin tile, but it is not, then we will detail understanding of the difference between PVC tile and resin tile. Pipeline repair project for temporary emergency suction drainage pipe inside the water, the conventional large flow submersible pump flow 400 m3 / h hundreds of kg, and the weight of the pump body diameter is larger, not easy to use, use this series of a buoy floating submersible pump for pipeline repair engineering efficiency improve several times, install and use the pump don't have to so complicated. Central clearing debris with floating, floating facilities are connected by a wire rope 6 on cross-strait fixed pier 7, connect the other end of the wire rope and buoy respectively 1, 6, and the other end of the buoy 1 also through wire rope connecting ring is connected with main tank 2 12, is equipped with warning signs on the main tank 2 logos, the connector on the main tank 2 through 8 connected to the pair of pontoon 9, 2 on one side of the main tank by "U" shaped link 3 and bolt fastener connected with rows grating lobes 4, 5 the lower end of the grating lobes 4 through the hinge bracket fittings and 10 activity connected to the pair of pontoon 9 11, deputy pontoon and buoy 1 connection.
Navigation marks that indicate the direction and limits of the fairway and the marks that hinder navigation include ten kinds of marks for crossing the river, for the coast, for the navigation, for the transition, for the head and tail, for the side, for the navigation, for the left and right navigation, for the position, for the flood, for the bridge and culvert. The traffic signal marks shall be set in the narrow, sharp turning sections or single-hole navigable Bridges, navigable buildings and construction sections that require navigation control, such as upstream and downstream vessels that cannot see each other and go in the same direction or in dangerous parallel or opposite directions. One-way sequential navigation or navigation prohibition shall be controlled by means of signals for ascending or descending vessels.
Ship mooring buoy manufacturer custom-made - the grid spacing for hydropower station depends on the type and size of the turbine to ensure that dirt passing through the grid will not get stuck in the turbine flow components. When we use more than one mold to roll molding the same plastic products, we can also add different colors of materials in different molds and roll plastic products of different colors at the same time. Suitable for forming various complex shapes of hollow parts. In the process of rolling molding, the material is gradually coated and deposited on the inner surface of the mold. At the same time, because the mold is not subjected to external pressure during the molding process, the mold with fine structure and complex shape can be made directly by means of precision casting.
