Since 1994, we has developed contact type oil baffle ( seal cover ) of complete new concept for large rotating mechanism, such as turbogenerating unit ( steam turbine, generator and exciter etc.), hydrogenerating unit ( hydrogenerator, thrust bearing of water turbine, top guide bearing and bottom guide bearing ), motor, pump and air blower, in order to prevent oil, water and hydrogen leakage. After testing and improving, we have provided power stations with this kind of products. More than 60 power stations have been installed more than 700 sets of TN series contact type oil baffle. The quality and property all meet the requirements of power stations, and it has been formed series products : TNN series of contact type oil baffle inside turbogenerator TNW series of contact type oil baffle outside turbogenerator TNG series of high temperature contact type oil baffle of turbogenerator TNX series of contact type oil baffle for small diameter shaft used in motor, air blower and pump TNS series of contact type seal cover of hydrogener There are many designers, marketing people and technicians for installation with rich experiences in the company and the company has systematic productive power of scale. The special design can be done according to the requirement of power stations besides standard design, in order to meet the requirement of unit property. Manufacture and installation can be carried out on time and we can offer after service of high quality.
