FAQs of RECIPROCATING PUMP TEST RIG:
Q: How does the reciprocating pump test rig operate for experiments?
A: The rig uses a single-cylinder, single-acting reciprocating pump driven by a direct-coupled electric motor at 1500 RPM. Water is drawn from the sump tank and discharged through the measurement system, enabling users to study pump performance under various flow rates and pressures within the specified range.
Q: What are the main benefits of using this test rig in a fluid mechanics lab?
A: This rig helps users understand the fundamental principles of reciprocating pumps, including flow, pressure, and discharge measurement. Its robust construction, corrosion resistance, and accurate analog displays make it a valuable teaching tool for reliable and repeatable experiments.
Q: When should this equipment be used in a laboratory setting?
A: The test rig is ideal for fluid mechanics curriculums, research projects, and practical training sessions. It is suited for laboratory exercises involving pump performance analysis, efficiency studies, and demonstration of pumping mechanisms.
Q: Where are the observation and sump tanks located, and why are their capacities important?
A: The 50-litre observation tank and 75-litre sump tank are integrated into the rigs structure for efficient water circulation during experiments. These capacities ensure sufficient water volume for uninterrupted operation and accurate measurement during extended sessions.
Q: What safety features are included to ensure operator protection?
A: The test rig is equipped with an overload protector for the motor, safeguarding users and the equipment from excessive electrical or mechanical strain during operation. This feature promotes a safe laboratory environment.
Q: How does material selection benefit the longevity and performance of the rig?
A: The use of cast iron for the pump and stainless steel for contact parts ensures durability, corrosion resistance, and extended equipment life. Powder-coated painting further protects against rust and wear, maintaining the rigs performance over time.
