High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam
Chemie Ingenieur Technik, EarlyView.This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.

RELIABILITY RESEARCH ON HYDRAULIC AXIAL PISTON PUMP
Proceedings of the JFPS International Symposium on Fluid Power, 1989 This paper describes the reliability of 25 SCY hydraulic axial piston pumps. On the basis of investigations, experiments and theoretical analyses, the pump failure mode and failure mechanism were found. The statistical study of test data was done, the failure distribution function and the distribution parameters were determined, and the pump life was ...

Research on wear prediction of piston/cylinder pair in axial piston pumps
Wear, 2020 Abstract The piston/cylinder pair is the critical lubricating interface of axial piston pumps. It suffers from excessive wear, especially under high output pressure. The performance degradation of the piston/cylinder pair is significant to be clarified. In this paper, a wear prediction method of the piston/cylinder pair is established by coupling the
