Laboratory Mixer in the long run, due to vibration, abrasion, temperature and pressure, repeated disassembly and so on, all of the static sealing parts prone to leakage, which caused a lot of waste oil, and affect the enterprise site management. To control the leakage of the traditional method to remove and open the mixer, replace the sealing gasket or apply sealant, but it is time-consuming and laborious, and it is difficult to ensure the sealing effect. The latest modern maintenance methods are mostly used in polymer composite materials, the main motor cooling unit cooling water pipe leakage

The tube plate of the mixer cooler is affected by the medium and the welding stress, so it is prone to leakage and corrosion.
