The suction valve plate is an important structure of corrosion-resistant water ring vacuum pump, but sometimes fracture occurs during use. The manufacturing process is closely related to this.
1. The pouring system, especially the sprue and runner, should not be coated, so that the gas generated during pouring can be quickly and fully drained, and the coating consumption can be saved.
2. The foam model must be dried before coating. Each batch of foam model should check the weight change of the drying process at present, and make the curve chart of baking weight change.
3, foam model density is small, in order to ensure the surface quality of foam, and ensure the model strength of corrosion resistant water ring vacuum pump, the foam should be made lighter and better, so as to reduce the volume of gas when pouring.
It is the knowledge that every manufacturer should know to take effective measures to avoid the rupture of suction valve plate of corrosion-resistant water ring vacuum pump, so as to avoid the loss in later use.
