  • NH3 Precision Anhydrous Ammonia Application for Systems

    Jan 27, 2015 · Anhydrous ammonia is stored and transported as a liquid. To maintain NH3 as a liquid it must be kept below –28°F or maintained under pressure. If the temperature of the NH3 increases above –28°F some of the liquid changes to a gas as the NH3 begins to boil. Application equipment typically uses tank pressure to deliver NH3 to the soil.

  • Maintenance and troubleshooting guidelines for a typical high

    Maintenance RequirementsPreparation Before MaintenanceMaintenance ProcedureSwitchgear SparesLubrication of Operating MechanismsTroubleshooting GuideMaintenance covers a wide range of activities, all of which are required to keep the switchgear in ready condition at all times to enable it perform its functions satisfactorily. The parts subjected to normal wear and agingneed to be serviced for ensuring full reliability of the operations. These parts may be mechanical components or electrical components. The interval at which the maintenance should be carried out depends upon the following factors: 1. The number of short-circuit interruptions 2. The switching frequency 3. The actual service time The actual conditions of use in terms of the frequency of operations, environment and severity of switching duty vary so much that it is impossible for the manufacturer to give detailed guidelines to the user concerning the frequency of maintenance. The latter components are likely to need periodic inspection and servicing only, to ensure that the equipment is free from dirt, dampness and deterioration, such as corrosion of metal work and...
