Shell-and-tube heat exchanger has become the most widely used heat exchange equipment in industrial process heat transfer due to its strong structure, large adaptability, and mature manufacturing process. The main components of the shell-and-tube heat exchanger include heat exchange tubes, tube sheets, baffles, shells, end covers, and connection tubes. According to different heat exchange media, it can be divided into: atmospheric condenser, lubricating oil cooler, water cooler, sea water heater, jacket water heater, oil heater, vacuum condenser, etc.
Atmospheric condenser is mainly used to recover the condensed water of various miscellaneous steam, the exhaust steam or condensed water heated by fuel oil, lubricating oil, daily water, etc., and the excess steam of the condensing waste steam boiler.
The oil cooler is mainly used to take away the heat absorbed when the oil flows through the bearings, gears, etc., to maintain a certain oil temperature and viscosity, to ensure the safe and reliable operation of the equipment.
Fresh water coolers are usually used to cool cylinders and pistons to prevent excessive temperature rise of these parts.
Tank washing sea water heaters are used on oil tankers to supply high-temperature seawater for tank washing.
Oil heater is usually used to heat fuel, lubricating oil or hydraulic oil. The fuel heater can make the inferior high-viscosity heavy oil be used to facilitate the delivery; the fuel entering the fuel injection pump is heated to a specified viscosity to facilitate atomization and combustion, etc.; the lubricating oil heater can make the lubricating oil reach the desired level before entering the oil purifier. The required temperature.
The role of the vacuum condenser is to establish and maintain a high vacuum at the exhaust end of the steam turbine, obtain a larger isentropic enthalpy drop of steam, improve the cycle efficiency, and condense the exhaust steam of the main and auxiliary steam turbines into pure condensed water to be supplied to the boiler.
The company mainly produces a series of deck and cabin machinery products: specifically shell-and-tube/plate heat exchangers, spark extinguishing silencers, hot well units, pressure water tank units, hot water tank units, water supply modules, air bottles, oil/water filters , Wire rope electric hoist, engine room crane, sea water desalination device, and constant pressure frequency conversion water supply unit, mud tank, radiator, heater, hose barge, etc., are widely used in various marine engineering, supporting ships, oil fields, chemical industry, In power and other fields, it has successively provided supporting products for major domestic shipyards such as Hudong Zhonghua, Jiangnan Shipbuilding, Shanghai Shipyard, Guangzhou Shipyard International, Dalian Shipbuilding Industry, Bohai Shipbuilding Industry, Qingdao Beihai Heavy Industry, COSCO Kawasaki and other major domestic shipyards.
