Marine oil station vertical pump set fastening vibration isolation backing ring

Abstract

The invention discloses a marine oil station vertical pump set fastening vibration isolation backing ring. The vibration isolation backing ring is installed between a top plate of an oil box and a middle cover flange of a pump set; the vibration isolation backing ring comprises a set ring, a seat ring and a plurality of connection bolts; the bottom of the seat ring is fixed to the top plate of theoil box, the set ring is fixed between the middle cover flange and the seat ring, and the middle cover flange, the set ring and the seat ring are connected together through the connection bolts; andthe set ring comprises two coaxially and vertically arranged pressing rings, two disc rings, two force bearing rings and a clamping ring. The vibration isolation backing ring provided by the inventionis connected with the pump set and the oil box into an organic whole. All the rings are nested with one another through trapezoid shoulders and trapezoid grooves, and vertical vibration force is partially dispersed in the horizontal direction to be converted into heat energy; the horizontal end surfaces of the rings are provided with blocking cavities and gaps, the vertical vibration force cannotbe directly transmitted in the vertical direction, in addition, the adjacent rings are made of different materials, vertical shearing force and horizontal shearing force can be additionally generated, thus, vibration energy is consumed, and vibration is effectively reduced.

Description

technical field [0001] The invention relates to a buckle-type vibration-isolation pad ring for a vertical pump set of a marine oil station, in particular to a buckle-type vibration-isolation pad ring for a vertical pump set of a marine oil station with a watertight and fireproof function, which belongs to the ship vibration reduction technology field. Background technique [0002] The marine hydraulic pump station performs missions for the ship, and provides and transports a steady stream of various pressure liquids for the normal life and work of personnel, such as supplying lubricating oil for the main engine and the auxiliary engine; providing hydraulic oil for the control system of the main engine and the auxiliary engine; Provide hydraulic oil for pitch control propeller; provide pressure liquid and lubricating oil for deck machinery such as steering gear, windlass, crane, etc. However, since the pump set of the marine hydraulic pump station is a moving machine that tr...

Problems solved by technology

However, the first and second methods cannot prevent the impact of environment and other equipment vibrations on the pump set, and the design and manufacturing costs are relatively high (this is also one of the main directions of current efforts to reduce vibration and noise); the third method follows As the use time increases, the shock absorber will gradually reduce the vibration reduction performance, and this method is not suitable for marine oil station pump sets with watertight requirements; the fourth method is not suitable for places with fire protection requirements
