Detailed explanation of animal husbandry fan construction preparation and basic inspection and acceptance

2020-04-03

Animal husbandry fan is a kind of equipment that is commonly used at present,It is widely used in industrial production and animal husbandry. Its operation principle is relatively simple, mainly because it is driven by the impeller to generate a driving force with the gas, so that there is a corresponding centrifugal force and corresponding energy between each other, and as a result, it can be delivered to the gas. During the installation of the fluid machine, it must meet scientific standards and have some awareness of its precautions. Operation and maintenance is one of the important links of its normal service to social production, so it needs special attention.

  1.Construction preparation

The unpacking inspection counts the parts, components and supporting parts of the animal husbandry fan according to the equipment packing list. All the parts and supporting parts should be complete. Check the main installation dimensions of the impeller, casing and other parts. Each dimension should be consistent with the design. The direction of the inlet and outlet of the fan should be consistent with the design; the direction of rotation of the impeller and the direction of guide of the stator guide vanes should meet the requirements of the technical documentation of the equipment.

  2.Equipment basic inspection and acceptance

The function of the equipment foundation is to fix the equipment, bear the weight of the equipment and its vibration force and transmit them to the soil, absorb and isolate the vibration generated during the operation of the equipment to prevent resonance. The quality of the equipment foundation directly affects the installation quality of the fan, so the equipment foundation should be checked and accepted before the equipment is in place,The inspection content includes the location of the foundation, geometric dimensions, and anchor bolt holes. Concrete strength, etc. The strength of the foundation concrete should meet the design requirements, and the strength report of the test block should be qualified. The center line of the equipment foundation should be popped up according to the equipment layout plan to check the location of the equipment foundation,Its plane position deviation should be less than soil10 mm. Location and depth of anchor bolt holes. The cross-sectional dimensions should meet the design requirements. There should be no oil, dirt and debris in the anchor bolt holes, and it should be dry and free of accumulated water. After the initial leveling of the livestock fan, the distance between any part of the anchor bolt and the hole wall should be greater than15 mm, The depth should reach the bottom end of the anchor bolt without touching the bottom. The overall deviation of the basic elevation is+20mm.-10mm,The relative deviation of the base of the wind shell bearing, the drive motor, etc. should be less than+1mm.
