Description

A maintenance-friendly transformer vacuum casting equipment pipeline storage device

technical field

The utility model belongs to the technical field of machinery, in particular to a pipeline storage device for vacuum casting equipment of a transformer which is convenient for maintenance.

Background technique

The traditional transformer vacuum casting equipment is composed of a premixing tank, a final mixing tank, a casting tank, a vacuum pump, a Roots pump, a filter system and a vacuum pipeline. When the vacuum pouring equipment is working, the first-stage vacuum pump works first to reduce the air pressure of the premixing tank, the final mixing tank and the pouring tank, and improve the vacuum degree. When the vacuum degree reaches within 2000pa, the secondary pump Roots pump starts to work, extremely Quickly minimize the air pressure in the premix tank, final mix tank, and pouring tank.

In the existing pouring equipment, due to the high degree of vacuum, the air pressure drops rapidly, and the vacuum pipeline is connected to the filter, the roots pump and the vacuum pump in a straight line, so the pouring raw material liquid is often sucked into the filter system, the roots pump and the vacuum pump. The phenomenon occurs in the transformer casting material. The epoxy resin and curing agent in the transformer casting material are volatile liquids with high viscosity. When they enter the filter system, the filter system will be blocked, and then the vacuum system will be hindered, making the premix tank , The vacuum degree of the final mixing tank and the pouring tank cannot meet the requirements, and the filtering system also loses the filtering effect. If it enters the vacuum pump and Roots pump, it is extremely difficult to clean, and the daily maintenance is extremely complicated, which greatly increases the maintenance cost of the equipment. For this reason, we propose a pipeline storage device for transformer vacuum casting equipment that is easy to maintain.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIG. 1 , the present utility model provides a technical solution: a pipeline storage device for transformer vacuum pouring equipment that is convenient for maintenance, comprising a pouring tank 1, a final mixing tank 2 connected to the pouring tank 1, and a final mixing tank 2 , The pouring tank 1 is connected with the vacuum pipeline 4, and the pouring tank 1 is connected with the filter system 6, the roots pump 7 and the vacuum pump 8 in turn through the vacuum pipeline 4, and it is characterized in that: the middle of the pouring tank 1 and the filter system 6 is connected by a vacuum pipe The road 4 is fixedly connected with the liquid storage bin 5, the bottom end of the liquid storage bin 5 is fixedly connected with the deposition pipeline 11, and the bottom of the deposition pipeline 11 is provided with a discharge valve 10, which is operated by the first-stage vacuum pump 8 to lower the pouring tank 1, the final The air pressure of the mixing tank 2 and the premixing tank 3 increases the vacuum degree.
