| Abstract | In civil aviation ground deicing system, the traditional reciprocating pump is often used as the power supply device to ensure the physical and chemical properties of high viscosity deicing fluid. The traditional reciprocating pump exist the problem of flow fluctuation. A new horizontal space multiphase crankshaft pump is proposed to suppress the flow fluctuation. The new type of pump adopts segmented crankshaft: each crank pin on the crankshaft drives two connecting rods simultaneously. The connecting rod drives the pistons distributed on both sides of the crankshaft to achieve linear reciprocating motion. Three sections of the crank pin are arranged by 120° phase space circular, and this kind of crankshaft implements multiple phase coupling of piston movement. The hydraulic cylinder adopts the horizontal layout, so the machine structure presents spatial symmetry. A mathematical model of two connecting rods driven by crankpin is established for the new type of pump. The kinematics equation of the piston is solved by the analytical method and then the flow rate of the pump is calculated. In contrast with the experimental data, the new pump can effectively reduce the flow fluctuation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
