How does anchoring and anchoring work in a ship? What is the state of the chain stopper anchor winch

Anchor preparation is the preparation before anchoring. When preparing the anchor, the first thing to do is to throw a single anchor or a double anchor according to the requirements of the bridge. Check whether the windlasser is normal and whether the brake is good, close the power of the windlass, tighten the brake a little tighter, and loosen the safety of the chain stopper.

If you find something in the nearby waters, report it to the bridge in time. Anchoring: When the bridge pulls a short air whistle, it is a signal to drop the anchor, then turn on the chain stopper, let the anchor drop into the water, in the process of anchoring into the water, to use gestures and lights to report the length and direction of the anchor chain to the bridge.

Generally, the length of the chain is 3 5 times the depth of the water, according to the angle between the anchor chain and the water surface, when the chain is about the same, it is necessary to brake with a brake from time to time, so that the anchor chain is effective, so that the anchor slowly goes deep into the mud, and after the bridge determines that the boat is pulled, then put the anchor chain to the appropriate length, put down the chain stopper, and install the chain stopper insurance. Hang the anchor ball at the end.

The two meanings of anchor preparation refer to the fact that the ship itself has a fixed number of anchors installed, and the additional number of anchors is also called anchoring, which is placed in other locations of the ship or in the base warehouse; The second refers to the work prepared when docking at the pier or when anchoring is about to be dropped. At this time, the windlass is energized and the chain stopper is opened. Anchoring refers to the process of starting the windlasse or gravity anchoring to make the anchor enter the water.

Are you the head of the water or the first mate?

Dear, we are glad to answer for you: At the same time, the engagement of the normally open contacts of the contactor is used to control the positive and negative, low-speed, medium-speed and high-speed operation of the motor in the main circuit. ZC is a forward rotation function contactor, which is anchored when energized.

FC is a reversing function contactor that breaks down when energized. 1c is a low-speed state contactor, and the motor is in a low-speed state when energized. The windlass is a very critical component in the marine equipment, it is able to work normally and reliably is related to the safety of the whole ship, at the same time, in the ship electrical equipment installation course students are required to be able to correctly install the three-speed windlass circuit, and be able to troubleshoot errors in the installation process, then I think that after mastering the electrical control principle of the windlass, it will make.

The installation circuit is simple and easy, the operation of the windlass circuit will be clearer, and it also provides a certain theoretical basis for the analysis and judgment of the failure of the circuit now or after the fiber. Quietly.

Hello, I am glad to answer for you: the marine three-speed windlass has several contactors to control the forward and reverse rotation and braking as follows; The principle of marine three-speed windlass is to drive the winch shaft to rotate through the two-stage deceleration of worm-worm gear and gear, and to install a pair of sprockets on the winch shaft and a pair of tooth inlay clutches with a slide key, and the clutch can slide axially through or virtual handles, so that it can be burned or separated from the sprocket mosaic shirt. When the anchor is lifted, the clutch is connected with the sprocket, the belt brake mechanism is relaxed, and the winch shaft can drive the sprocket to rotate; When the anchor is dropped, the clutch is separated from the sprocket, and the belt brake mechanism is relaxed, and the dead weight of the anchor can be used to throw out.

Disengage the clutch and brake the sprocket with the brake belt, the winch shaft only drives the winch barrel to rotate, which can be used to twist the cable. The sprocket shaft of the vertical electric windlass is installed perpendicular to the deck, and the motor and reducer can be arranged below the deck.

Man-made reasons, due to staff operation errors or poor daily maintenance, the main phenomena are: the insulation protective layer of electrical circuits, the insulation of electrical circuits is soaked in water or seriously damp, and the metal parts drop cover seeps into the wire terminal when the equipment is in operation or the staff maintenance; The failure caused by the defects of the equipment itself, such as the poor quality of the factory equipment, is mainly concentrated in the causes of poor insulation or insulation damage, aging of equipment insulation, and material deterioration. 1) Fault phenomenon.

The symptoms of short-circuit fault are more obvious, the current is very large, the fuse is burned, the protective electrical appliances are in action (thermal relay, current relay), and the related equipment can not work normally, and the serious short-circuit fault can cause the line edge to burn out or the transformer coil to burn out, the contactor to burn out and the contact sintering and other phenomena. 2) Cause of failure. When the windlass is running, the load of the negative object is high and low, unstable, and overloaded; Improper operation of the windlass operator; The circuit in the electrical control box of the windlass is aging, the equipment is trapped and the quality is not up to standard.

Summary. The adjustment of the brake of the marine electric windlass can be achieved by adjusting the brake disc pressure and brake stroke. First, the friction of the brake disc can be increased or decreased by increasing or decreasing the brake stroke.

Secondly, the amount of friction can be controlled by adjusting the gap between the brake disc and the brake shoes. Finally, it is necessary to ensure that the brakes are working properly, including preventing the brakes from overheating, keeping the inside of the brakes clean, etc.

Excuse me, but please go into more detail?

The adjustment of the brake of the windlass can be achieved by adjusting the brake disc pressure and brake stroke. First, the friction of the brake disc can be increased or decreased by increasing or decreasing the brake stroke. Secondly, the amount of friction can be controlled by adjusting the guess gap between the brake disc and the brake shoes.

Finally, it is necessary to ensure that the brakes are in normal working condition, including preventing the brakes from overheating, keeping the inside of the brakes clean, etc.
