Copyright Goodheart-Willcox Co., Inc. Chapter 8 Fluid Storage and Distribution 203 4. You are called to troubleshoot a pump that is very noisy when operating near capacity. The noise started after the system reservoir was replaced with a different model. What questions would you ask about reservoir design and installation to determine what is responsible for the change in system operation? List at least three questions you might ask and explain how the answers to these questions will assist you in your troubleshooting process. Research and Development 1. Investigate the current trend toward use of smaller hydraulic reservoirs. Determine what is motivating this trend and the technological advances that may be supporting it. 2. Prepare a report that describes the fl uid storage and distribution system of a specifi c model of skid loader. Your report should include specifi c information about reservoir design, conductor type and size, and conductor connections used, as well as a discussion of how these specifi c components affect the operation and capacity of the loader. 3. Research the design, composition, and capacity of hydraulic hose used in an extreme environment, such as extreme temperature environments or high system pressures. Be prepared to explain how the design and materials allow the hose to withstand the conditions in which it operates. 4. Design and perform an experiment to measure or illustrate how average fl uid velocity changes as cross-sectional area of the conductor changes. 18. It is typically recommended that the average fl uid velocity in a hydraulic system working line should not exceed _____ feet per second. A. 20 B. 30 C. 60 D. 100 19. True or False? Straight-line connections should be avoided when fi tting tubing in order to avoid excessive stress on materials and fi ttings. 20. True or False? Low- and high-pressure hoses are often clamped together. Apply and Analyze 1. Describe how you might modify a fl uid storage and distribution system to reduce overheating of hydraulic fl uid during operation. 2. If the pump fl ow rate in a simple hydraulic system is 10 gpm and the maximum system pressure is 3,000 psi, what size reservoir and conductors for pump inlet and working lines would you choose to install? Why? 3. What are the possible effects of replacing a pump inlet line with a conductor that has an inside cross-sectional area half the size of the original line? What information do you need to determine if your conductor size is adequate for system operation?
