Vacuum pressure impregnation equipment

The design is generally divided into four sections during the design of the vacuum pressure dip coating section: the dip-coating zone, the machine room, the control room and the drying room zone. Under the premise that the fire rating of the vacuum pressure dipping zone is determined, in order to design and construct the plant economically and reasonably, it is necessary to design the plant in a sub-region.

According to the design specifications for electrical installations in fire hazard environments, the explosive atmosphere shall be partitioned according to the frequency and duration of the explosive gas mixture as follows:

Zone 0: an environment in which continuous or long-term explosive gas mixtures occur;

Zone 1: An environment in which a gas mixture may explode during normal operation;

Zone 2: An environment in which an explosive gas mixture is unlikely to occur during normal operation, or an environment where only a short-lived explosive gas mixture is present, even if it occurs.

The immersion paint tank and the paint storage tank are arranged in the immersion paint zone, and the entire varnishing process of the motor is completed in the varnishing zone. The paint storage tank is a tank for storing insulating paint. Under normal circumstances, the lid of the paint storage tank will not open, and the tank is in a vacuum state. If the tank is not filled with an inert gas such as nitrogen, then the paint liquid in the paint storage tank The surface is a continuous release source. The dip-coating tank is a jar of motor immersion paint. The motor is hoisted in the immersion paint tank after vacuuming, painting, pressing, painting, and painting. Before the can lid is opened, the residual styrene vapor in the dip tank is pumped to the exhaust gas purification treatment device through the suction device of the tank body and the tank mouth, and is discharged at a high altitude, even though a small portion may be volatilized into the ambient air of the dip tank. It is only a short time.
