The valves closing delay angles are defined. The sphere valves altitude above a valve seat at the piston checkpoints moment is justified. The pump volumetric efficiency definition method is finished. The method of definition general efficiency and power demands of the electric motor is offered. The pump reliability augmentation excite by to application pump pillar hinged fastening is justified. The considered mortar pump engineering designing method is offered. Field of mortar pump application is justified and the economic benefit of mortar pump introduction is counted. The detail project is designed. The prototype is made and successfully has passed working testing. Product Description popup.authors popup.nrat_date 2020-04-03 Close
