APPLICATION OF WATER RING VACUUM PUMP IN CANNING MACHINE

The vacuum pumping system consists of a vacuum pump, a pressure stabilizer, a dust collector, and a valve link retainer. The selection of vacuum degree and air volume of vacuum pump is the key to the success of V method appearance. The normal maximum vacuum in consumption is around -66500pa (-500mmhg). The pressure stabilizer is a sealed container, whose function is to stabilize the pressure of the vacuum system, to buffer the influence of the system pressure on the appearance, and to filter dust. Dust removal tank; Sandbox for a long time the recycle and pouring molten iron on the formation of a sandbox screen pack's destroyed easily damaged, the sand is formed in the suction vacuum pump wear and tear, had better be in into the vacuum pump money increase dust catcher, link dust removal tank the last into the vacuum pump, to ensure the using life of vacuum pump.When selecting vacuum pumping system, the capacity of vacuum pump should be confirmed first.Application-of-water-ring-vacuum-pump-in-canning-machine

Consider the following elements:

1. The size and quantity of sand boxes that need to work in a vacuum at the same time;

2. The number of casting types simultaneously cast;

3. Size and shape of casting;

4, close to the film's cast appearance of permeability, it controls through the plastic film on the gap amount of air into the mold, so when pouring, casting coating helps to provide a "auxiliary seal layer".
