Abstract
The invention discloses an installation method for the elastic shock absorbers of a marine generator set, wherein the compression amount H of each of the elastic shock absorber at the bottom of the marine generator set is obtained by standing a motor for 24-60 hours, compression amount compensation gaskets with thicknesses which are matched with the compression amount H are machined according to the compression amount H, and the machined gaskets are arranged at the bottoms of the elastic shock absorbers with the corresponding compression amount H, thus the level degree of the motor can be easily adjusted, and then the accuracy of the adjustment is ensured; operating personnel do not need to manually observe and adjust the level degree, therefore, labour intensity is greatly reduced, installation cycle is shortened, and working efficiency is high.
Description
Technical field
The present invention relates to the installation method of the elastic dampers of marine generator group.
Background technology
The generator set of boats and ships is placed on generator set mounting, between generator set and generator set mounting, needs to arrange elastic dampers, to play the effect of vibration and noise reducing.At present, the installation method of elastic dampers is that traditional jackscrew is adjusted method, in generator set bottom, distribute a plurality of elastic dampers are set, and the generator set with elastic dampers is placed on mounting, between elastic dampers and generator set mounting, be provided with jackscrew, by manual observation generator set, whether place level, if out-of-level, on short one side, regulate this to locate corresponding jackscrew, by rotation jackscrew, regulate the height of elastic dampers herein, thereby adjust generator set height, make generator set keep horizontal positioned.Due to when regulating jackscrew, need a plurality of operating personals lift together generator set, thus just can manual shift jackscrew height, labour intensity is very large, and because do not lift steady generator set, generator set accidentally falls, and can cause personal damage sometimes; In addition, owing to being manual observation generator set levelness, therefore, needing constantly to adjust jackscrew height, thereby lengthened installation period, even need tens talentes to install, work efficiency is extremely low.Once run into, need elastic dampers be installed according to the requirement of sharing of load, traditional jackscrew adjustment method will can not reach requirement completely.
Summary of the invention
The present invention is intended to provide and a kind ofly can carrys out according to generator set actual payload distribution condition the installation method of the elastic dampers of leveling generator set levelness.
The installation method of marine generator group elastic dampers of the present invention, its step is as follows:
1), fixedly mount belowdecks generator set mounting;
2), elastic suspension is arranged on the feet of generator set bottom;
3) in the elastic suspension mounting hole that, the generator set of installing after elastic suspension is installed on generator set mounting, elastic dampers is placed in arrange on generator set mounting;
4), by generator set on generator set mounting standing 24 ~ 60 hours;
5), measure the amount of compression H of each elastic dampers of generator set bottom;
6), according to the amount of compression H of each elastic suspension, be its amount of compression compensate gasket of matching with it of preparation, the amount of compression compensate gasket of the preparation that amount of compression H is large is thicker, the amount of compression compensate gasket of the preparation that amount of compression H is little is thinner;
7), lifting generator set, the amount of compression compensate gasket for the preparation of each elastic suspension is placed in respectively to the bottom of corresponding elastic dampers;
8), the generator set of installing after elastic suspension and amount of compression compensate gasket is installed on generator set mounting, make elastic dampers and amount of compression compensate gasket be positioned at the elastic suspension mounting hole arranging on generator set mounting;
9), connect elastic suspension and generator set mounting, complete installation.
The installation method of marine generator group elastic dampers of the present invention, by the pre-installation of generator set, recorded exactly elastic suspension that each generator set feet the installs amount of compression in the actual loading situation, by amount of compression compensate gasket is installed below elastic suspension, the thickness of amount of compression compensate gasket and the elastic suspension deflection under concrete load matches, the relatively large elastic suspension of amount of compression can coordinate installs the larger amount of compression compensate gasket of thickness, the elastic suspension that amount of compression is relatively little can coordinate installs the less amount of compression compensate gasket of thickness.It is by the amount of compression H that records according to actual loading situation and adjust the thickness of amount of compression compensate gasket, the levelness of regulator generator group very easily, generator set is installed after in horizontality, effectively guaranteed the precision regulating.And it is without operating personal manual observation levelness and regulate levelness, therefore, greatly reduces labour intensity, has shortened installation period, work efficiency is high.
