Abstract
The invention discloses a configuration scheme for the air compressor of a multifunctional overhead travelling crane. The scheme is realized by replacing an existing high-displacement air compressor by two low-displacement air compressors, wherein the total displacement of the two low-displacement air compressors is greater than the displacement of the existing high-displacement air compressor. With the adoption of the scheme disclosed by the invention, electricity utilization can be saved by 43%; and the life of the multifunctional overhead travelling crane is far greater than the life of an overhead travelling crane continuously using a 75 KW air compressor; simultaneously, the working rate of the overhead travelling crane is guaranteed and increased due to good maintenance. The two 37 KW air compressors are greater than the 75 KW air compressor in working stability, and superior to the existing configuration in the aspects of power, energy conversion, maintenance, life, stability, service efficiency and the like; therefore, with the adoption of the scheme disclosed by the invention, the use performance and adaptability of the multifunctional overhead travelling crane are remarkably improved.
Description
Technical field
the present invention relates to a kind of Air compressor allocation plan and multifunction crane of multifunction crane, belong to for the Air compressor configuring technical field on the electrolysis multi-function crane of 500KA electrolytic bath and the service of above grooved.
Background technology
electrolysis multi-function crane is the key equipment of large-sized prebaked Aluminium Electrolysis in potroom, be mainly used to prebaked anode Aluminium Electrolysis process crust breaking, feed in raw material, blow ash, go out aluminium and propose the operations such as framework.In these operations, need to use pressurized air to coordinate, so be provided with Air compressor at electrolysis multi-function crane.
have now as generally only being provided with the Air compressor of a 75KW on the electrolysis multi-function crane of 500KA electrolytic bath and above grooved service, its free air capacity is per minute 12m

.Usually go out aluminium larger with the gas consumption of proposing the framework operation; And crust breaking, reinforced and to blow the gas consumption of grey operation less.
current this configuration, when being gone out aluminium and proposing the framework operation, slightly feel the tolerance deficiency, but, when carrying out crust breaking, feed in raw material and blowing grey operation, tolerance has more than needed.In general, the multifunction crane of potroom is used for aluminium and only accounts for 15% of the whole service time with the time of proposing the framework operation, therefore has serious unreasonable allocation problem.Owing to only having configured at present an Air compressor, this Air compressor is all used in all operations, is unfavorable for energy-conservationly, also directly affects service life of Air compressor, and fault rate is also higher, needs often to shut down maintenance, and impact is produced.Use alerting ability also poor.Therefore the compressed air source on the reasonable disposition multifunction crane, be to solve above-mentioned in-problem gordian technique.
Summary of the invention
the object of the invention is to, a kind of Air compressor allocation plan and multifunction crane of multifunction crane is provided.The energy consumption existed with the solution prior art is large, the life-span is short, fault rate is high, impact is produced, the deficiency of use very flexible.
technical scheme of the present invention
the Air compressor allocation plan of multifunction crane, this scheme is to substitute an existing large free air capacity Air compressor with two float tolerance Air compressors; The exhaust total amount of two float tolerance Air compressors is greater than the free air capacity of an existing large free air capacity Air compressor.
in aforementioned schemes, the exhaust total amount of described two float tolerance Air compressors is per minute 14m
