NOTE: This guide specification covers the requirements for testing, adjusting, and balancing (TAB) of heating, ventilating, and air-conditioning (HVAC) air and water distribution systems.
FOREWORD This handbook has been extensively updated for 2002 from the original 1983 publication and includes all of the many changes that have takes piace in the industry since the 1990's. We have added many new sections covering variable frequency drives (VFD), direct digital control (DDC)...
This document recommends general designs, tolerances, limits of application and suitable tooling, fixtures and accessories for mounting and driving jet engine rotors on horizontal and vertical balancing machines.
This document recommends general designs, tolerances, limits of application and suitable tooling, fixtures and accessories for mounting and driving jet engine rotors on horizontal and vertical balancing machines.
Thoroughly revised, this book provides the reader with an understanding of the principles and practices of testing and balancing (TAB) heating, ventilating, and air conditioning (HVAC) air and water systems. For the novice and the experienced testing and balancing technician,...
QUALIFIED PRODUCT LIST OF PRODUCTS QUALIFIED UNDER PERFORMANCE SPECIFICATION MIL-I-27209 Indicator, Temperature, Thermocouple, Self-Balancing, Potentiometer Type This QPL has been prepared for use by or for the Government in the acquisition of products covered by the subject specification...
The aim of this text is to provide a comprehensive set of calculations relating to mass and energy balances for an entire process plant. An ammonia synthesis plant will be taken as a calculation model to develop the relevant mass and energy balances necessary for the design and...
Abstract On a multi-access network, one of the PIM-SM (PIM Sparse Mode) routers is elected as a Designated Router. One of the responsibilities of the Designated Router is to track local multicast listeners and forward data to these listeners if the group is operating in PIM-SM. This document...
This standard specifies functional requirements and specific safety requirements for free-standing balancing beams.
Applies to rotors balanced in balancing machines, in their own housing and in situ.
This International Standard specifies a single convention for balancing the individual components (shafts or rotors, and fitments) of a keyed assembly. It is intended to provide compatibility of all balanced components so that when they are assembled they will meet the overall balance...
This Data Item presents four procedures for the design of counterweights which, when fixed to shafts rotating with constant angular velocity, improve the balance of machines that incorporate single degree-of-freedom, planar, multibar linkage mechanisms. The frame shaking force† and/or the...
This document specifies those requirements and procedures for periodic tests to insure maintenance of balance machine capabilities for balancing jet engine components. It will specify: (a) Requirements for tests (b) Calibration tests (c) Residual unbalance and accurate angle and...
