Welcome to inquire! Contact: Zhang. Many manufacturers may not be very great importance to suppress the bellows from the factory before the test this step, often producing completion of delivery to the customer to install buried rubber joints, often there is a problem in the course, began to search for the origin of the problem. Pressure test can help you verify whether bellows qualified, accurate discovery problem. Today I'll tell you about corrugated compensator pressure test before leaving the factory. Currently, the majority of seal design welded flange structure that is welded at both ends of the compensator flange, flange face for a smooth sealing surface rubber joints, flange pipe flange on both ends of the bolts to tighten it seal can be achieved. However, this design larger defects exist in practice. When the compensator form with both ends welded flange connection is a four-ball rubber joints, the first flange sealing surface processing quality will put forward stringent requirements, but such compensation welding assembly precision fixed structure, is also very big test. Even when the compensator assembly precision component itself can meet the requirements Rao tetrafluoroethylene rubber joints, but compensation is applied to the inner tube, bellows assembly needs to be connected at both ends of the pipe. Thus, the spatial position of the connecting flange or threaded through hole locations are likely to go awry, and this bias would be such a fixed compensation component structure produces torque, seriously affecting the life of the compensator.
