1, test machine parts should always wipe clean, no paint surfaces wipe clean after application of cotton yarn with a small amount of oil and then wipe it again, to prevent rust, during the rainy season should pay more attention to clean, not when the dustproof cover covers to prevent dust intrusion.
2, the cabinet to control all valve should not be placed to prevent dust entering the internal opening, impact sensitivity, measurement mechanism.
3, long-term frequent use may cause oil decreases or deterioration, should be based on the use of every month 1-3 check once oil quantity. The equipment stops running 15 minutes, was observed in the control cabinet of the left oil window, if the oil level is below the oil window is added with the hydraulic oil to the oil window intermediate position; such as the oil has gone bad, must change the new hydraulic oil.
4, the frequent use of the equipment to do the tensile breaking test may lead to a portion of the fastener loosening. Shall frequently inspect the following parts of the fastening situation:
A. The upper beam and the movable beam before and after each have two ( 8 ) ( L press plate play guiding role of each jaw board ), each with 2 screw fixing plate;
B. The movable cross beam ends of each of the 6 screws;
C. Every 6 months to check a screw drive chain tightness, adjust the tension wheel position ( the need to remove the lower part of the main body panel after );
In 5, according to the environmental conditions and the use of frequency, every 3 ~ 6 months on the following parts of lubrication:
A. Screw rod and the base junction, to No. 100 oil lubrication;
B. A screw rod drive chain with grease;
C. Screw screw parts clean and with butter or molybdenum disulfide lubricant;
AB two lubricating are required to remove the lower part of the main body panel after.
In 6, the upper beam and the movable cross beam on the 2 device with a jaw clamp jaw, is the important parts, shall be based on the use of often clear the jaw clamping plates and the crossbeam on contact surface debris, so as not to scratch the contact surface. Method: remove the movable beam side of the platen, removal of jaw plates, oil cloth respectively the jaw plate and beam contact surface cleaned, coated with an appropriate amount of butter and graphite mixed oil, return the jaw plate after plate fixation screw tightening.
