Cooling water system of refrigerating machine of ocean vessel

Abstract

The invention relates to a cooling water system of a refrigerating machine of an ocean vessel. The cooling water system comprises a cooling water circuit, a water pump (1) and a condenser (2) are arranged on the cooling water circuit, a filter (3) is disposed between the water pump (1) and the condenser (2), a valve I (5) is arranged on a water inlet pipe of the condenser (2), a valve II (6) is arranged on a water outlet pipe of the condenser (2), a backwash pipeline I (8) is arranged between the front end of the valve I (5) and the front end of the valve II (6) in a connection manner, a backwash pipeline II (9) is arranged between the rear end of the valve I (5) and the rear end of the valve II (6) in a connection manner, a valve III (10) is disposed on the backwash pipeline I (8), and a valve IV (11) is disposed on the backwash pipeline II (9). The cooling water system of the refrigerating machine of the ocean vessel has the advantages that failure rate of refrigerating machine equipment is reduced, maintenance expense of the equipment is saved, running reliability of the equipment is improved, and workload of maintenance staff is greatly reduced.

Description

technical field [0001] The invention relates to an ocean-going ship ice machine cooling water system, which is used to improve the ocean-going ship ice machine cooling water system, reduce the failure rate of the ice machine, provide suitable temperature and humidity for the ship's food fresh-keeping store, and prolong the storage time of food. Background technique [0002] The task density of ocean-going ships is getting higher and higher, and the cycle is getting longer and longer, and the requirements for food preservation are getting higher and higher. How to adapt to the needs of the task, effectively reduce the failure rate of the ice machine equipment, and ensure the good operating condition of the equipment is a difficult problem that must be overcome. [0003] Ocean-going ships have 3 low-temperature storages—meat storage, fish storage, and quick-frozen vegetable storage, 5 high-temperature storages—fruit storage, vegetable storage, dairy product storage, grain stor...

AI Technical Summary

Problems solved by technology

The long-term operation of the cooling water pump not only increases the wear and tear of the wearing parts of the water pump and increases the maintenance cost, but also increases the frequency of dismantling and cleaning after the ice machine cooler is dirty and blocked, which increases the work intensity of the maintenance personnel

Moreover, the cooling water channel in the condenser of the ice machine is U-shaped, and the material is thin-walled copper tubes. It is easy to be damaged when the condenser is dismantled and cleaned, which makes the ice machine unusable.
