SU1636934A1 - Suspended hydraulic generator - Google Patents

Abstract

The invention relates to electrical engineering, in particular to suspended turbine generators. The goal is to improve the installation conditions and increase the reliability of the hydrogenerator. The hydrogenerator has an oil bath, a sub-tank, comprising a housing, which in turn is made of a cover 3, a shell 4 and an annular bottom 5 connected by an oil-tight seam. The implementation of the vertical wall of the body bath in the form of a solid shell eliminates the possibility of oil leaks from the bath and its vapor in the machine room. 4 il. . with SS V)

Description

baths from the side of the inner diameter of 45 Ho # readiness collected on a single 50

A cylindrical enclosure 17 is installed.

In order to soothe the turbulence of the surface layers of the oil, an oil damper plate 18 located at the level of the oil surface is installed directly on the oil coolers 6. 1l of the possibility of adjusting the high-altitude position of the oil damping plate 18, it is fixed on the vertical studs 19 with the counter-elements 20 fixed to the sections of the oil cooler.

On the ground and bonded between the shell 4, the oil coolers 6, the oil cooler 18 and the body of the seals 28, together with the handrails 31, are installed on the outside of the sub-tube 10 (Fig. 4). The finally assembled body of the bath with the oil-coolant bodies is fixed on the upper cross and not with fasteners.

With a sufficiently large radial section of the lid 3, it acquires a second function — the service platform, from which the seal housing is installed;

on the platform and bonded between the shell 4, the oil coolers 6, the oil cooler 18 and the body of the seals 28 together with the handrails 31 are installed on the outside of the subnet 10 (Fig. 4). The finally assembled body of the bathtub with oil coolers is fixed on the upper cross with fasteners.

With a sufficiently large radial section of the cover 3, it acquires a second function — a service platform, from which the seal body 28 is installed, the state of the sealing cuffs 29, the fastener elements of the locking ring and the case 30, the state of fixing and fixing the sleeve 21 and its locking ring is checked. .

The implementation of the vertical wall of the body bath in the form of a continuous annular shell rigidly connected to the lid eliminates the possibility of oil leakage from the bath and its vapor entering the power house of the hydroelectric station. This increases the operating reliability of the submersible, eliminates the likelihood of stopping the hydraulic unit, and thus eliminates the shortage of electricity.

The oil bath design provides access to all elements of the bogie and to the oil coolers with a minor amount of disassembly and assembly work.
