Precautions for use of tensile testing machine

In daily use of tensile testing machines, the maintenance of individual components and hydraulic universal testing machines are the main models on the market for testing machines. The maintenance of its main internal parts also directly affects the use of the testing machines.

Maintenance and maintenance of transmission mechanism:

1. The lower beam lifting of the hydraulic universal test machine main machine is driven by the reducer through a chain, which drives the two lead screws to rotate simultaneously. The lead screw rotates in situ to drive the transmission nuts on both sides of the lower cross beam to rotate up and down simultaneously, thereby achieving the rise of the lower cross beam. Note: Due to the limited load capacity of the reducer, the lower beam can only move under no load.

2. Method of chain tensioning: There are two sets of tensioning mechanisms on the front and rear sides of the base. Loosen the six-screws on the upper side and adjust the small nut on the tie rod. The chain is tightened. The two tensioning mechanisms cooperate to adjust. After adjustment, tighten the hexagonal screws.

3. Add molybdenum dioxide to the chain every six months; check the chain tightness every six months. If the chain is loose, the screw will not be synchronized, which may cause the screw to get stuck.
