Abstract
The invention discloses a fresh water cooling circulation system for an immersed ballast pump motor of a semi-submersible platform. The fresh water cooling circulation system comprises a fresh water cooling and supply ring conduit 4 and a fresh water cooling and return ring conduit 3, wherein the fresh water cooling and supply ring conduit 4 is connected through a pipeline for providing cooling water to a user; the fresh water cooling and return ring conduit 3 is used for refluxing the cooling water to the user after cooling; the fresh water cooling and return ring conduit 3 is connected with a heat exchanger 10 through the pipeline; fresh water cooled by the heat exchanger 10 is conveyed to the fresh water cooling and supply ring conduit 4 through a fresh water cooling pump 1; the fresh water cooling and supply ring conduit 4 is also provided with a pipeline interface which is used for conveying the cooling water to the ballast pump motor 5 through the pipeline; and return water cooled by the ballast pump motor 5 is conveyed to the fresh water cooling and return ring conduit 3 through a motor cooling water pump 2. A cylinder sleeve of the ballast pump motor employing the fresh water cooling mode is made of a carbon steel material, so that the cost is about 1/4 to 1/5 that of an SUS316 motor cylinder sleeve; the cost can be greatly saved; and the fresh water cooling circulation system is an initiative design, and has the advantages of being high in automatic degree, relatively low in cost, safe and reliable.
Description
Technical field
The present invention relates to the cooling of semi-submerged platform immersion ballast pump motor, more particularly, relate to the improvement of the existing type of cooling.
Background technology
Enter the semi-submerged platform of ABS classification society, ballasting system need have after the water inlet of pump room, still to have at least two ballast pumps can the ability of effective emptying each non-damaged compartment cabinet, and its requirement exceeds other classification societies.For meeting this requirement, ballast pump can be designed to immersion IP68 degree of protection ballast pump, and this pump can work under certain submergence after pump room water inlet.Because immersion ballast pump motor is the totally-enclosed cylinder sleeve design of IP68, motor cannot dispel the heat by carrying fan, need be taken away, the heat that cylinder sleeve inner motor produces in order to avoid motor is overheated by external refrigeration water.External refrigeration moisture seawater and fresh water two kinds, the seawater branch road that the former utilizes ballast pump to export cools, and integrated by pump, shipyard is without the need to extra work, but motor cylinder sleeve is for avoiding seawater corrosion, need be SUS316 by the material design of cylinder sleeve, manufacturing firm be few, and manufacture difficulty is larger, price is higher, be generally 4 ~ 5 times of fresh water cooled type carbon steel cylinder sleeve, as used the program, shipyard cost pressure is larger.
Summary of the invention
The present invention solves the cooling problem of immersion ballast pump motor by the mode of fresh water cooled, specifically by the motor cooling water pump be arranged in the upper deck case of maximum damage waterline, overcome the height fall between pump room and deck case and pipe resistance, the water route realized between fresh water cooled water supply, backwater endless tube is communicated with, and then realizes the fresh water cooled of immersion ballast pump motor.
In order to achieve the above object, the invention provides a kind of semi-submerged platform immersion ballast pump motor fresh water cooled circulatory system, comprise and being attached thereto as user provides the fresh water cooled water supply endless tube of cooling by pipeline, and the fresh water cooled backwater endless tube 3 of the described user's cooling water of backflow after cooling; Described fresh water cooled backwater endless tube is connected to heat exchanger by pipeline, and the fresh water through cools down is pumped to described fresh water cooled water supply endless tube through fresh water cooled; Wherein, described fresh water cooled water supply endless tube is also provided with pipeline interface cooling water being delivered to ballast pump motor through pipeline, and the cooled backwater of described ballast pump motor sends described fresh water cooled backwater endless tube back to through motor cooling water pump.
Under optimal way, described motor cooling water pump entrance inlet porting break valve, described motor cooling water pump outlet sets gradually outlet pressure sensor and outlet screw down nonreturn valve.In addition, the cooled backwater outlet of described ballast pump motor arranges outlet temperature sensor.
For semi-submerged platform, fresh water of the present invention respectively arranges a set of through fresh water cooling pump, motor cooling water pump, ballast pump motor, outlet temperature sensor, inlet stop valve 7, outlet screw down nonreturn valve, outlet pressure sensor, heat exchanger at semi-submerged platform structure port and starboard; And described fresh water cooled backwater endless tube, fresh water cooled water supply endless tube are respectively a set of ring-type pipeline.
The ballast pump motor cylinder sleeve of fresh water cooled mode of the present invention is carbon steel material, and cost is about 1/4 ~ 1/5 of SUS316 motor cylinder sleeve, greatly can save cost.The present invention is initiative design, has the advantage that automaticity is high, cost is lower and safe and reliable.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the semi-submerged platform immersion ballast pump motor fresh water cooled circulatory system of the present invention.
Embodiment
Semi-submerged platform immersion ballast pump motor cooling system of fresh water of the present invention, primarily of following equipment and pipeline composition: as shown in Figure 1, fresh water cooling pump 1 arranges two, be arranged in left and right side of a ship pump room respectively, its discharge capacity is identical, single pump discharge capacity meets the demand of whole platform fresh water cooled user, only pump operation during work, and another pump is in standby mode; Motor cooling water pump 2 is for overcoming pipe resistance, backwater is lightered in backwater endless tube 3, it is arranged in the deck case on the maximum damage waterline meeting ABS code requirement, and its import and export connects fresh water backwater endless tube 3, fresh water cooled water supply endless tube 4 respectively by pipeline; The pipeline of the entry and exit of motor cooling water pump 2 is provided with respectively outlet screw down nonreturn valve 8, outlet pressure sensor 9, inlet stop valve 7; Fresh water backwater endless tube 3, fresh water cooled water supply endless tube 4 are for the cooling of full platform fresh water user, be set to endless tube mainly for the consideration of fresh water cooling pump 1, heat exchanger 10 the using and the reserved, arbitrary the pump cooling that all can not affect fresh water user on endless tube out of service; The outlet of ballast pump motor 5 is provided with outlet temperature sensor 6.
Operating procedure:
As shown in Figure 1, valve member in ballast pump motor cooling system of fresh water is all in open mode, when platform needs adjustment ballast trim, operator sends and starts ballast pump instruction, complex control system is starter cooling water pump 2 first, fresh water in ballast pump motor 5 is lightered to continuously in fresh water backwater endless tube 3, when complex control system monitors after outlet pressure sensor 9 has pressure to change, then perform and start ballast pump program.Cooling effect reads in complex control system by outlet temperature sensor 6, namely realizes the cooling of ballast pump motor.
