Abstract
A utility model relates to a large turbine type generator cooler leakage detecting device, comprising a sink below the generator cooler, one set or more sets of water collection leak detection modules composed of a water collecting can, a water collecting tube and a limitation monitor for monitoring the leakage condition and communicated with the sink and mounted below the sink. When the cooler leaks, the leakage condition is timely monitored, therefore the workman can quickly examine and repair to prevent the failure from generating, thus the motor can in failure free operation. Compared with the prior technique, the large turbine type generator cooler leakage detecting device has features of simple structure, lower cost, reliable performance, high sensitivity and convenient mount and maintenance.
Description
Technical field
The utility model belongs to generator cooling system auxiliary facility technical field, is a kind of large turbo-type generator water leakage of cooler pick-up unit.
Background technology
In technique known; be used for monitoring the measure that generator cooler leaks and takes: below the generator cooler heat interchanger, put a drip tray; regularly see by the staff and to look; because the refrigeratory of high-rating generator is usually located at the top of generator; whether refrigeratory leaks is difficult in time finding; have only when the spill-over of drip tray water goes out; just can learn water leakage of cooler; keep in repair disposal this moment again; for the time later, so poor reliability is when serious the leakage especially occurring; generator is broken down because of internal temperature sharply raises, even cause great stopping accident.In order to address this problem effectively, disclose a kind of intelligent detection device in the prior art, this device is that hundreds of wall-sticking leakage sensors are attached on the sidewall of refrigeratory below, and utilizes intelligent data acquisition unit and computing machine to report to the police, show.Though this device can in time detect the situation of leaking, it is too many that it detects components and parts, lays numerous and diverse, installation and maintenance trouble, and manufacturing cost is too high, is difficult to popularization.
The utility model content
The purpose of this utility model provides a kind of simple in structure, dependable performance, convenient and practical large turbo-type generator water leakage of cooler pick-up unit.
Realize the technical scheme that the purpose of this utility model is taked: a water receiving tank is set, and the assembly that leaks hunting that catchments that one or more groups is communicated with it is housed in the bottom of water receiving tank below generator cooler.
Described catchment leak hunting assembly by water collect tank, collector pipe and the spacing monitor that is used to monitor the situation of leaking form, wherein, an end of collector pipe is communicated with water collect tank by joint, and the other end is communicated with water receiving tank, spacing monitor is positioned at the water collect tank top, and its gauge head is stretched in the nearly water collect tank.
What described spacing monitor adopted is liquid tuning fork limit switch.
According to the large turbo-type generator water leakage of cooler pick-up unit that such scheme is made, when refrigeratory takes place to leak water, can in time find the situation of leaking, so that the maintenance of staff's fast processing guarantees the normal operation of generator by monitoring device.Compared with prior art, this device has simple in structure, cheap, dependable performance, highly sensitive, advantage such as installation and maintenance are convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Embodiment
Referring to Fig. 1, large turbo-type generator water leakage of cooler pick-up unit of the present utility model is made up of the water receiving tank 1 that is installed in generator cooler below, one or more groups assembly that leaks hunting of catchmenting, the assembly that leaks hunting of catchmenting is made up of collector pipe 2, water collect tank 6 and spacing monitor 4, one end of collector pipe 2 is connected the downside position of water collect tank 6 by joint 3, the other end is communicated with water receiving tank 1, the upside position of water collect tank 6 is provided with bleeder vent 5, the bottom is provided with the screw plug 7 that discharges water, and the spacing monitor 4 that is used to monitor the situation of leaking is equipped with at the top.In case when the heat interchanger in the refrigeratory leaks, can collect in the water receiving tank 1, promptly introduce in the water collect tank 6 by collector pipe 2.Spacing monitor 4 adopts liquid tuning fork limit switch, be installed in the top of water collect tank 6, its gauge head puts in the jar, when the water level in the jar reaches certain height of water level, this spacing monitor 4 can utilize the sound wave principle to send alerting signal, reminds the staff in time to dispose.The upside position of water collect tank 6 is provided with bleeder vent 5, equates with outside atmospheric pressure to keep a jar internal pressure.The bottom of water collect tank 6 is provided with the screw plug 7 that discharges water, and after finishing once maintenance, the ponding in the water collect tank 6 all can be emitted, and guarantees the original state under the non-leakage situation.Monitoring device of the present utility model is simple in structure, and is cheap, and water leg 1 can be according to the corresponding configuration of the quantity of cooling heat exchanger.When disposing a plurality of heat interchanger in the refrigeratory, can only be equipped with one group of assembly that leaks hunting that catchments, the leaking collection in a plurality of water receiving tanks is passed in the water collect tank 6 monitors; Also can below the correspondence of each heat interchanger, respectively dispose one group of assembly that leaks hunting that catchments respectively, leak, reduce maintenance load so that know which heat interchanger exactly.
Claims (3)
1, a kind of large turbo-type generator water leakage of cooler pick-up unit is characterized in that: a water receiving tank is set below generator cooler, and in the bottom of water receiving tank the assembly that leaks hunting that catchments that one or more groups is communicated with it is housed.
2, large turbo-type generator water leakage of cooler pick-up unit according to claim 1, it is characterized in that: described catchment leak hunting assembly by water collect tank, collector pipe and the spacing monitor that is used to monitor the situation of leaking form, wherein, one end of collector pipe is communicated with water collect tank by joint, the other end is communicated with water receiving tank, spacing monitor is positioned at the water collect tank top, and its gauge head is stretched in the nearly water collect tank.
3, large turbo-type generator water leakage of cooler pick-up unit according to claim 1 is characterized in that: what described spacing monitor adopted is liquid tuning fork limit switch.
