The utility model discloses a system layout is equitable, and work efficiency is high, makes whole power device system pipeline the shortest simultaneously, reduce cost, sexual valence relative altitude.
Description
Technical field
This utility model relates to a kind of water cooling system, is specifically related to a kind of New Marine cluster engine sea water cooling system
System.
Background technology
During Ship Power Equipment work, having a large amount of plant equipment heat to be given out, the function of cooling system is exactly to needing
Equipment to be dispelled the heat is provided with enough fresh water, sea water, river or cooling oil, cools down, to ensure that it is at normal temperature model
Enclose interior work.Cooling system generally comprises the cooling the most main and auxiliary machine of object, other cooled equipment and seawater gate, valve member, heat friendship
Parallel operation, sea water pump or the equipment such as fresh water pump, expansion tank.It follows that the design of cooling line or other pipeline is not
Isolated carrying out, it should consider contact native system within, consideration native system is with the contact of other system, conjunction to be chosen again
The design parameter of reason, makes system connection and reasonable arrangement, and work efficiency reaches the highest, makes whole power plant system pipeline the shortest simultaneously,
Material saves most, investment minimum, this just design to power set propose the highest requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of New Marine cluster engine sea water is cold
But system, reaches to control generating set temperature, reduce energy consumption, protection electromotor the purpose extending its service life.
For realizing above-mentioned target, the technical solution of the utility model is:
A kind of New Marine cluster engine salt water cooling system, main frame uses closed cycle cooling i.e. sea water cooling fresh water；
Main frame sea water pump sucks sea water from seawater main, point two-way, and a road enters from main frame, colder through oil cooler and fresh water after elder generation
But the cooling of device, finally gets rid of outboard, and outboard is discharged on another road after gear-box oil cooler cools down；Described main generator sea
Water pump sucks sea water from seawater main, enters main generator and directly cools down, then discharges outboard after main generator fresh-water cooler；
Described main frame cooling system of fresh water utilizes what main frame carried fresh water cooling pump to beat the fresh water that cyclic high-temperature fresh water carries through main frame
Cooler cools down；
The heat exchange cooling water inflow of main frame and main frame oil cooler and main frame fresh-water cooler is 40.5m3/h。
Further, described cooling sea water pump discharge capacity is 55m3/ h, lift 0.35MPa, gear-box heat exchange cooling water inflow
For 10.2m3/ h, main frame water at low temperature cooling water inflow is 40.5m3/h。
Further, all pipes in cooling water system should be III grade of piping, this piping for steam and hot coal oil
Design pressure P1≤ 0.7MPa, design temperature T1≤170℃；Design pressure P for fuel oil2≤ 0.7MPa, design temperature T2≤
60℃；Design pressure P for other media (empty gas and water, lubricating oil and hydraulic oil etc.)3≤ 1.6MPa, design temperature T3≤200。
Further, various pipelines all use seamless steel pipe or welded still pipe, and cooling water pipe all uses zinc-plated seamless steel pipe,
The adapter of Pressure gauge instrumental panel uses seamless copper pipe.
Further, sea water tank volume is 4.5m3/, totally 2, it is distributed in the port and starboard of hull.
Further, fresh water expansion tank is 0.9m3, bottom exceeds main generator cylinder cover 2-3m, lower termination a-road-through
Footpath be the filling pipe of 25 on main generator high temperature cooling system of fresh water, be used for supplementing in main generator high temperature cooling system of fresh water
The water run off because of evaporation, filling pipe specification selects the zinc-plated seamless steel pipe of DN25, a size of Φ 34 × 2.5mm, main generator height
The peak of temperature cooling system of fresh water pipeline arranges Reuter's trachea and is connected to fresh water expansion tank, for whole main generator high temperature
Breathing freely in cooling system of fresh water, permeability cell specification selects the zinc-plated seamless steel pipe of Φ 6 × 1mm.
The beneficial effects of the utility model are: the most isolated cooling line is carried out the design of systematized inside and outside, logical
Crossing rational parameter adjustment, make system connection and reasonable arrangement, take up room little, work efficiency is high, shortens whole power plant system
Pipeline, saves material, reduces cost.
