[Abstract]:Seawater hydraulics using seawater as the working medium of hydraulic system, which is compatible with the marine environment, no pollution, good fire resistance, large power, easy maintenance, simple structure and other advantages, so it has wide application prospect in the field of marine engineering. This paper studies a can work directly in seawater plunger reciprocating pump in deep sea and the pump has a pump automatic balance inside and outside pressure, corrosion resistance, miniaturization, light weight and other advantages, which can meet the needs of work in deep-sea environment.
This article is divided into five chapters.
In the first chapter, the significance and application of deep-sea seawater pump are introduced. The research status in this field at home and abroad is analyzed. The key technologies of seawater pump development are analyzed, and the main contents of this paper are expounded.
The second chapter introduces the overall goal of sea water pump is developed, the first chapter relates to the technical problems of sea water pump was studied to determine the overall structure of the water pump to form reciprocating piston pump. The forward pump parts material selection, structural parameters of the pump are calculated.
The third chapter through the comparison of the commonly used pressure compensation technology to the sea water pump, this paper determined the pump using bladder type pressure compensation device. The compensation volume needed bladder compensation pump crankcase pressure was calculated, and the availability of the compensation method is verified through the experiment.
The fourth chapter through the analysis of the shortcomings of the seawater pump working environment and common plunger seal, puts forward a new type of plunger seal - Lancaster seal ring, the piston through the ANSYS compression size on the sealing performance of stepseal slip analysis, friction performance, through the experimental study of the high-pressure chamber to verify the correctness of the available and the simulation theory stepseal in seawater on the pump.
The fifth chapter through the comparison of the flow structure characteristics of the common seawater pump valve, analysis of pump performance requirements, determine the cone valve used. According to the design formula of preliminary determination of valve parameters, analysis of the clearance volume, valve spool by AMESim software quality, environmental pressure, influence of preload parameters on pump performance fixed part, parameter of valve, analyzes the different design principles of pump valve with deep seawater pump and land. Through the experiment verified the correctness of the cone valve parameters and simulation theory, and some properties of the pump were studied.
The sixth chapter makes a summary of the full text, and looks forward to the next step of the research.
