Yingkou Ship Repair is also classified into daily maintenance work. It is mainly divided into three types: daily maintenance, monthly maintenance and suspension maintenance. Among them, suspension maintenance is divided into two types: semi-annual maintenance and annual maintenance. The daily maintenance is carried out every day, the monthly maintenance is carried out once a month, the semi-annual inspection is carried out for 500-600 hours of operation of the main engine or once every six months, and each inspection is carried out for 3-5 days. As for the annual inspection, the main engine is operated for 1000-1500 hours. Or once a year, every 3-7 days.

Ships started from prehistoric wooden boats and experienced the era of canoes and wooden boats. After the world's first steel boat came out in 1879, the era of steel boats began again. The propulsion of ships has also evolved from relying on manpower, animal power and wind power (that is, pitching, paddling, swaying, stringing and sailing) in the 19th century to the use of machinery.

In 1807, Fulton in the United States built the first steam engine ship "Clermont" with paddle wheel propulsion at a speed of about 8 km/h; in 1839, the first steam engine ship equipped with propellers, "Aki The "Mead" came out with a main engine power of 58.8 kilowatts. This kind of propeller fully demonstrated its superiority, so it was quickly promoted.

In 1868, China's first steamship "Huiji" with a load of 600 tons and a power of 288 kilowatts was successfully built. In 1894, British Parsons used his invented reactionary steam turbine as the main engine, installed on the "Turbine", and successfully sailed on the Thames, with a speed exceeding 60 kilometers.

The steam turbine and the propeller of the early steam turbine ship were at the same speed. About 191 [2] 0 years later, gear reduction, electric transmission reduction and hydraulic transmission reduction devices appeared. After this, ship steam turbines began to adopt the reduction transmission method.

Repairs are carried out daily maintenance, so as to keep the ship in a good technical and seaworthy state. Let's share with you about ship maintenance.

As far as the definition of daily maintenance of a ship is concerned, daily maintenance of a ship refers to the maintenance of the ship in a good technical and seaworthy state during the interval between the ship’s second plan to enter the factory for repairs, and is mainly carried out by the crew or the crew. The daily maintenance or troubleshooting of the ship and various equipment by technicians to maintain the daily state of the ship.

The following principles should be followed in daily maintenance:

1. Pay attention to safety. Focus on prevention, pay equal attention to self-cultivation, and adhere to the principle of diligence and thrift. 2. The principle of combining daily maintenance with suspension inspection. 3. The department should do a good job of supervision and implement the principle of inspection and maintenance.
