Description
Technical Field
The utility model relates to a slag screening technical field, especially a hydraulic generator set inside oil gas condensation suppression device.
Background
When the hydraulic generator works, the oil gas in the hydraulic generator inevitably generates condensation. After the condensation, the generator wind tunnel, waterwheel room ground will form corresponding long-pending oil level, not only the polluted environment, fortune dimension personnel are patrolling and examining or the periodic overhaul in-process carrying out daily equipment moreover, if do not notice the long-pending oil level that the condensation formed, easily take place to slip, bring serious bodily injury for the staff.
In addition, these condensed hydrocarbons can cause damage to the hydro-power plant. When condensation occurs, the lubricating effect among all internal mechanical structures can be reduced, and meanwhile, lubricating oil forms a corresponding blocking surface after being mixed with other dust, so that the normal operation of systems such as unit ventilation and the like is influenced, and huge damage is brought to the unit. Specifically, there are several disadvantages as follows.
And the first damage can cause severe heating and temperature rise of the stator of the hydraulic generator. When leading out on hydroelectric set and appearing a large amount of oil gas and spilling over the phenomenon, will form a lamination oil level at generator stator coil skin, including turbine oil itself just has very strong viscosity, can be at the dust around the continuous adhesion stator coil of stator coil ventilation hole department this moment, along with the extension of operating duration, the dust radius increases gradually and blocks up generator stator coil ventilation hole, and make the inside stator coil of generator generate heat and can not effectively discharge, constantly accumulate and form the temperature rise phenomenon that generates heat, can influence the high-efficient steady operation of generator when serious.
And secondly, the insulation level of the stator of the generator is reduced. Can lead to the inside stator coil ventilation system of generating set to high-efficient stable operation after the oil gas condensation, the temperature rise that generates heat violently of stator coil can destroy the inside operational environment of stator coil, influences stator coil's normal heat dispersion to arouse the inside stator insulation level of generator and descend, and reduce gradually along with operational environment's deterioration.
And the third problem is that single-phase grounding or interphase short circuit and other accidents of the stator coil of the generator can be caused. When the hydroelectric generating set is in a large amount of oil gas condensation operating condition, if suddenly meet impact such as abnormal load, will produce great impact electromagnetic torque in generator stator coil department. Under the combined action of the violent heat effect and the dynamic effect, the stator coil of the generator can be damaged, and single-phase earth fault can occur; in severe cases, the stator winding of the generator is also damaged in an insulation manner, so that the interphase short circuit fault of the stator coil occurs, and great damage is brought to the generator.
And fourthly, increasing the maintenance difficulty of the stator coil of the generator. The inside adsorbed dust impurity of stator coil because a large amount of oil gas condensation, at the generator maintenance in-process, can greatly increased stator coil maintain the maintenance degree of difficulty. For a small amount of hydro-turbo generator sets with oil-gas condensation problems, the maintenance and the repair of the stator coil generally only need to spend about 12 working hours, and for the set with a large amount of oil-gas condensation problems, the working hours required by the maintenance and the repair of the stator coil are about 3-4 times of the working hours of a normal set, namely for the set with a large amount of oil-gas condensation phenomena, at least more than 40 working hours are needed, and the maintenance and the repair workload of power station maintainers is greatly increased.
And fifthly, increasing the probability of the tile burning accident of the generator bearing bush. The oil-gas condensation of a large amount of oil-gas of the generator set can cause the operating oil level of the bearing to drop sharply, and a fault danger point occurs, so that the probability of burning accidents of the guide bearing bush is increased, and the generator set is caused to have unplanned shutdown accidents.
The harm of the oil gas condensation problem to the hydroelectric generating set is very serious. After oil and gas pollution, the stator is locally heated, the insulation margin is reduced, safety accidents are easily caused, and the loss is immeasurable.
Therefore, the phenomenon of oil gas overflow and condensation always troubles the safe and stable operation of the water turbine generator set, and no established method exists for treating the problem of oil gas condensation inside the water turbine generator set at home and abroad, and the oil gas condensation problem is determined according to specific conditions and roughly divided into the following categories: such as improving the sealing structure; increasing the space of the oil groove; the arrangement and power of the oil gas absorption device are selected; avoiding the negative pressure zone, etc. Specifically, the following problems exist.
Problem one, improving the sealing structure is the most convenient way to deal with. With the development of the technology, the contact type seal is applied to the water turbine generator set in a large area, and replaces the traditional non-contact type seal. The non-contact type sealing mainly has the phenomenon that oil gas overflows from a position between the oil basin cover and the rotating shaft, although the contact type sealing has a good effect of inhibiting the oil gas overflow, the requirements on installation and production quality are high, and the requirements on the oil gas overflow and the oil gas overflow are different in actual application. The main problems of contact sealing are focused on the wear resistance of the sealing teeth and the jamming of the spring structure, which leads to the failure of the contact sealing.
Problem two, enlarging the internal space of the oil groove is a very effective method. The increase oil groove space mainly is the space between increase fender oil circle and the oil groove apron, lets oil gas can not form a high pressure district very fast. However, in practical applications, the oil sump arrangement space of each guide bearing of the generator is limited, and it is difficult to increase the internal space of the oil sump in the limited space.
The third problem is that the arrangement and power selection of the oil gas absorption device need to be researched, the optimal oil gas absorption position is selected, the power of the proper oil gas absorption device is selected, and the oil gas absorption effect is not influenced by the selection of the power. The current domestic and imported oil gas absorption devices have larger effect difference, and domestic equipment has poor filtering effect and is easy to lose efficacy due to saturation; imported equipment is in poor after-sale service and cannot be replaced in time.
And the air negative pressure area is formed by the design of an air path when the negative pressure is avoided in the space of the lower part of the rotor bracket and the upper part of the contact type seal. The negative pressure area of the water turbine generator set adopting the closed circulating ventilation structure exists all the time.
Therefore, various current oil gas condensation treatment measures are all temporary solution and non-permanent solution. Therefore, the oil-gas condensation inhibiting device in the water turbine generator set is designed according to the oil flow condition in the oil tank and the stirring characteristics of the oil flow in the oil tank under different rotating speeds by the company so as to solve the problems.
