D48S / Z-type davit machine structure, the principle cause of the malfunction and maintenance points
Company to arrange the wheel scraping the bottom water in Qinhuangdao Port. Effect is obvious after cleaning marine growth, reduction of ship resistance, ship speed increased,[link widoczny dla zalogowanych], fuel consumption reduced. 3 end of the ship and measure of pollution (1) when dry-docking, hull sandblasting rust should be smooth, uniform paint, rust corrosion of the hull is not easy, not easy attachment of marine organisms. (2) selection of good quality anti-rust paint and antifouling paint, antifouling paint and rust attention to the compatibility of the hull to prevent rust and prolong stain of efficiency, to resist the formation of sea creatures. The use of anti-fouling paint should meet the requirements of environmental protection, to facilitate the protection of the marine environment. (3) According to the operation of the ship, and if possible, appropriate arrangements for the ship into the water port, the ships soaking water, slowing the formation of sea creatures. (4) When the ship there is a certain degree of fouling resistance increases when the ship sailed, to avoid overload of the host state in the long-running, load the throttle control unit, exhaust temperature override control of the host, so the speed characteristics propeller characteristics to adapt to change, reducing the host fuel consumption. Host should be strengthened during the maintenance, increase the effective power of the host, the host in a relatively stable condition. (5) The ship fouling more serious, timely arrangements for docking or to take water to wash scraping the bottom end, clear sea creatures,[link widoczny dla zalogowanych], to eliminate fouling of the ship. However, loss of underwater paint will scrape the bottom, scraping the bottom dock after the repair should be timely. (Marine Technology) 2005 1 pattern shows: ① This figure is only schematic representation. Does not represent the actual original size, but the basic line with original shape, position and working principle. ② not draw the shell, some just back pads, snap ring and shaft. ③ 5 and 4 non-contact gear, gear 3 and 4 coaxial, gear and shaft sleeve 6 (clutch release, you can freely rotate around the shaft), gear 10 and shaft key connection, one-way stopper connected with the shaft key . ④ internal friction of two pieces, three pieces of outer friction plates, friction plates inside the 10 on the bite in the gear. External friction on the teeth bite put on film. Figure 3D48S / Z-type davit Working principle diagram (closed boats). , (3) Manual receive a boat down a heavy hammer handle clockwise roll. Clockwise rotation of gear 8, a gear 5 rotate counterclockwise rotation of a gear 2, a boat close by order of electric transmission. (4) The brake friction generated inside and outside friction plate and the one-way non-stop drive clockwise, the two are indispensable. (5) speed limit, by the tightness of the clutch. After dismantling,[link widoczny dla zalogowanych], found the boat could not put down the main reasons: ① davit machine depends mainly on the speed limit and brake friction plate inside and outside the mutual friction between the friction plate. But the question of friction is friction, each will have a certain amount of powder friction (friction layer powder), powder fall outside the guidance alveolar friction plate in a long time, a lot of powder accumulation, can easily cause internal and external friction plates jamming, locking gear 10 and shaft remain,[link widoczny dla zalogowanych], causing the boat can not fall down or can not break the boat. ② One-way stop, spring, plunger, straight pins, corrosion may be killed, one-way stop failure, leading to falling boat. After hanging around the boat maintenance machine used properly. 3 Maintenance Points (1) recommended every six months on the speed limiter device were opened again. Remove the locking bolt hammer a screw out of a light with a screwdriver can easily pry out the clutch the clutch outer cover. Put the focus on clean teeth and gear 10 of the alveolar alveolar, remove the 5 friction plates clean and check the thickness of friction layer (governor limit friction plate thickness 0.5mm, disc friction disc is 0.15mm), not wipe the inside and outside friction surface oil and butter. (2) Every six months,[link widoczny dla zalogowanych], one-way stoppers were opened once a key check mandrel is active, if the card is dead, must make it active, the internal add oil. (3) tablets prolonged use can cause friction and wear, resulting in a heavy hammer down position. At this point you can pull out the hammer rod upward one or two teeth. The hammer as far as possible to maintain the level of the state bar. Davit machine is an important safety equipment on board, the use of low, but sometimes accidents happen and the emergence of the boat can not fall down boats fault, it must be given adequate attention. IMO MEPC 52 meeting, a new particularly sensitive sea areas specified in the meeting, MEPC also designated the Oman Arabian Sea region (OmanAreaoftheArabianScas) as a special area, and the specific terms included in the revised MAR. Annex I of POL. Annex I of the other special areas are: the Mediterranean Sea, the Baltic Sea, Black Sea, Red Sea, \In the special waters. Will discharge oil waste (dischargeofoilywastes) adopt a more stringent control.
