Design and fabrication of a pneumatic grease pump Department:Mechanical Engineering By: Microns Project ID: 9728 Rating: (5.0) votes: 1 Price:₦5000 Get the Complete MaterialAbstractProper machinery lubrication is essential in preventing premature bearing failure, reducing friction, dissipating localized heat, and avoiding catastrophic downtime in industrial plants and automotive maintenance workshops. Conventional manual lever-type grease guns are labor-intensive, generate low and inconsistent delivery pressures (frequently failing to overcome blocked grease nipples), suffer from air entrapment, and expose operators to severe muscular fatigue. This project details the design, fabrication, and experimental evaluation of a portable, high-pressure Pneumatic Grease Pump utilizing differential pneumatic area intensification. The system comprises a double-acting reciprocating pneumatic air motor cylinder (diameter 75 mm), coupled via a stainless steel connecting rod to a submerged high-pressure grease plunger (diameter 10.6 mm), operating across an effective pressure intensification ratio of 50:1. When powered by a workshop compressed air line at 6.0 bar (87 psi), the pump generates an output grease discharge pressure of up to 300 bar (4,350 psi) with an average volumetric delivery rate of 0.82 kg/min for standard NLGI Grade 2 lithium grease. A spring-loaded rubber follower plate with a quad-lip wiper seal prevents cavitation and air pockets within the 15-liter mild steel reservoir. Performance testing indicated a volumetric efficiency of 88.4% and an operational air consumption rate of 0.16 m³/min under sustained continuous discharge. The fabrication utilized readily available engineering materials, including mild steel for the reservoir and chassis, 6061-T6 aluminum for the air cylinder barrel, and hardened chrome-plated 4140 alloy steel for the high-pressure plunger. The total manufacturing cost was evaluated at $285.00, demonstrating a 62% cost reduction compared to imported commercial pneumatic dispensers of equivalent capacity while offering exceptional ergonomics, reliability, and maintenance convenience for automotive garages and manufacturing workshops. ...Preview Download Preview +Other Mechanical Engineering project topics and materials you might be interested in»Design of an indirect evaporative cooling system for preserving perishable farm produce»A project report on the design and construction of adjustable drawing table and stool»Design, construction and testing of beans threshing machine»The design and assembling of a tricycle engine (Paggio)»Design and construction of adjustable drawing table and stool»Design and fabrication of groundnut shelling machine»Design and construction of a pneumatic water pumping machine»Modern washing machine, principles of operation and maintenance»Design and fabrication of electrical motorized bicycle wheelchair»Fabrication and construction of window burglar proof»Design and fabrication of domestic deep freezer»Construction and fabrication of charcoal oven»Fabrication of an industrial trolley»Fabrication of a pepper grinding machine»Design and construction of journal bearing demonstration rig
