Abstract


Seawater hydraulic transmission hydraulic system with sea water as the working medium, compatible with the marine environment, no pollution, anti-flammability good, big power, easy maintenance, simple structure, etc., which in the marine engineering field has extremely broad application prospects . This paper studies a work directly in the deep waters of the plunger reciprocating pump, the pump has a pressure difference between the inside and outside automatic balancing pump, corrosion wear resistance, small size, and light weight, etc., so that it can meet the environmental work in the deep sea needs. This paper is divided into five chapters. The first chapter introduces the development of deep sea water pump meaning and application in the field of research status at home and abroad, analyzes the key technology developed sea water pump, and overall describes the main contents of this paper. The second chapter describes the overall goal of developing sea water pump, it is the first chapter relates to the technical aspects of sea water pump were studied, studied in this paper to determine the overall structure of the sea water pump plunger reciprocating pumps form the form proposed pump parts Optional materials, the basic structure of calculation parameters of the pump. Chapter by sea water pumps used to the pressure compensation technology compared to determine the pump is studied in this paper Bladder pressure compensation devices. Calculating a pressure compensated pump crankcase bladder volume compensation required size and verified by testing the availability of the compensation. The fourth chapter analyzes the working environment of sea water pump plunger cavity sealing requirements and common shortcomings, we propose a new type of piston seals - Manchester seal ring, plunger through the ANSYS analysis of the slip ring compression seal for Manchester volume size of the sealing properties, friction performance, high-pressure positions through experimental study tested Stepseal availability on the sea water pump and simulation theory is correct. Chapter by comparing the sea water pump with flow valve with flow characteristics of the structure used to analyze pump performance requirements, determine the use of cone valve with flow. According to the preliminary design formulas to determine the parameters with flow valve, using AMESim software analyzes the clearance volume valves, valve quality, environmental pressures, preload parameters such as the impact on pump performance, revised valve with some parameters analyzed deep sea sea ??water pump with pump and valve terrestrial different design principles. Poppet verified through test parameters and some simulation theory is correct, and the pump part of the performance were studied. Chapter VI of the full text are summarized, and future research are discussed.
