Description
Technical field:
Present invention is mainly used for a kind of devices of water-cooled generator and commutation machine rotor coil cooling water end.
Background technique:
Currently, the water supply dress of all water-cooled generators and the commutation machine rotor coil cooling water used for raising power grid quality
Setting all is using packing form, and this packing is simply to realize rotatable parts and fixation by mechanical pressure for watertight construction
Sealing between component, rotating part set with fixed part set will result in packing abrasion greatly, although so packing form price compared with
It is low, structure is simple, but maintenance personnel is needed to realize compensation to abrasion because wearing the excessive mechanical pressure that must often adjust.It is cooling
Water pressure of supply water is generally all at 6 kilograms or so, and such as regular visit adjustment mechanical pressure will result in cooling water and largely let out not in time
Leakage, it is very big to generator and the decline of commutation machine rotor coil cooling effect, because cooling water leakage leads to rotor coil heating absolutely
Edge layer short service life, or even the shutdown that causes the accident because temperature is excessively high bring huge economic loss to using enterprise, especially
Be it is present require to improve from fatigue resistance, to generator and the confidential realization few man on duty of commutation or unattended, this requires that hair
The rotor coil temperature of motor and commutation machine must should ensure that be run in safe temperature range, and therefore, one kind is badly in need of in this field
Can long-term stable operation, do not need routine adjustment mechanical pressure again to guarantee the water supply device of cooling water supply.
Summary of the invention:
The present invention is directed to propose a kind of technical solution for meeting this field and being badly in need of water supply device, ideally solves this field
This technical problem, is mainly technically characterized by, it has seal joint, packing sealing ring, conjunction bolt, water supply hose, O-shaped close
Seal, water supply branch pipe, the upper mounted plate with horizontal waist-shaped hole, the bottom plate with pedestal and vertical waist-shaped hole, have
The spider in heart hole is fixed on by 4 center disc carriers close to main shaft side center inside rotation suction hose, and rotation is inhaled
4 water holes are formed between water pipe internal diameter and 4 center disc carriers and spider, are one or more groups of suctions being fixed with 3
The impeller shaft of wiper blade passes through the center bolt in impeller fixing axle and passes through the centre bore on spider is fixed with center nut
On rotation water suction tube hub, suction hose is rotated by rotary flange and is fixed on the master with water supply connecting flange with conjunction bolt
On axis, the fixation water chamber by one end with packing sealing ring and seal joint is covered in concentric fashion by water supply lumen pore to be rotated
Outside suction hose, adjusted by the upper mounted plate with horizontal waist-shaped hole and the bottom plate with vertical waist-shaped hole and pedestal
Fixed water chamber is fixed on base by bolt with conjunction bolt, and the regulating valve with water supply hose passes through water supply branch pipe and water supply
Hole is fixed on water supply blind flange center, the water supply blind flange mounting flange for conjunction bolt being fixed on fixed water chamber
On.Bottom plate with vertical waist-shaped hole and the upper mounted plate with horizontal waist-shaped hole are mainly used for adjusting in fixed water chamber
Water supply lumen pore and rotation suction hose concentricity, so as to packing sealing ring not eccentric wear, due to water-cooled generator or commutation machine revolving speed
It is 3000 revs/min, so suction pressure and flow that the impeller that the blade in the present apparatus forms generates are certain, therefore is equipped with
Regulating valve adjusts pressure of supply water and flow, so that pressure of supply water and flow is slightly less than impeller and generates water suction negative pressure and flow, solid
Determine to generate certain negative pressure when remaining at generator or the operation of commutation machine in water chamber, to guarantee not having at packing sealing ring
There is cooling water to leak out, meets generator or the cooling required water consumption of commutation machine rotor coil, such as one group of impeller do not become
When pressure greater than 6 kilograms of pressure of supply water or so, multiple groups blade can be increased to increase water suction negative pressure, it is ensured that in fixed water chamber
For negative pressure.
What technical solution technical effect achieved provided by the invention was realized in: rotation is fixed on by impeller shaft
When 3 blades in suction hose reach same revolving speed with generator or the operation of commutation machine, i.e., 3000 revs/min, to confession
Cooling water is answered to form water suction negative pressure and water supply flow, cooling water enters generator by water hole and main shaft inner cavity or commutation machine turns
It is cooled down inside subcoil, is formed by water suction negative pressure and is centainly greater than 6 kilograms of pressure of supply water, prevent cooling water from close from filler
It is leaked out at seal ring, while also available adjustment valve adjusts water pressure to meet the technical requirements of fixed water chamber negative pressure.
Technical solutions according to the invention structure is simple, dexterously by one or more groups of blades be placed in rotation suction hose in
Generator or commutation owner's axis rotate together, and form water suction negative pressure and remove maintenance personnel's periodic maintenance adjustment from, for generator or change
Camera is unattended or few man on duty provides reliable technology and guarantees.It is existing to packing machinery pressure in this programme and this field
Power technology is compared with novelty, creates performance and practicability, and this field and related fields will be widely used in.
