In the process of using the calorimeter, many users will encounter the troublesome problem that the barrel cannot be hit, which not only affects the progress of the experiment, but also may cause safety hazards due to improper operation. Don't panic, the following is a summary of common causes and corresponding solutions for you. It is simple and easy to understand and can be seen at a glance.

First, check the power supply and line connection

If the barrel can't hit, first check the basic power supply problem. Check whether the power plug of the calorimeter is plugged in tightly and the socket is powered on normally; then check the wiring inside the instrument to see if it is loose, aging or broken. If the wiring problem is found, it needs to be replaced or reconnected in time to ensure that the power supply is stable. This is the premise of the normal operation of the barrel.

Second, check the mechanical transmission parts

The operation of the bomb barrel relies on mechanical transmission. If the transmission parts fail, the bomb barrel will not be able to start. Focus on checking whether the transmission gear and belt are worn, stuck, and whether the bearing is short of oil and rust. If the gear is seriously worn, it is necessary to replace the same type of parts in time; if the belt is loose, the belt tension can be adjusted appropriately; for bearings that are short of oil, apply an appropriate amount of special lubricating oil to restore the flexible rotation of the parts.

III. Confirm the barrel seal and buckle status

The aging or deformation of the sealing ring of the barrel, or the buckle is not fastened tightly, will cause the barrel to fail to close normally, triggering the protection mechanism and failing to start. Carefully check the sealing ring, if there is aging or damage, immediately replace the new sealing ring; at the same time confirm whether the buckle is completely fastened. If it is loose, readjust the buckle position to ensure that the barrel is closed tightly and eliminate the start obstacle.

IV. Inspection of sensors and control systems

Some calorimeter barrels cannot be hit, which is caused by sensor failure or abnormal control system. Check whether the pressure sensor and temperature sensor are blocked or damaged by foreign objects. If the sensor fails, it needs to be replaced in time; if you suspect that the control system is faulty, you can try to restart the instrument. If the problem persists after restart, you need to contact a professional to overhaul the control system to avoid blind operation and expansion failure.

If the barrel of the calorimeter cannot be hit, follow the above steps to check one by one, and most problems can be easily solved. If it still cannot be repaired after self-investigation, do not disassemble the instrument without permission, and contact the manufacturer or professional maintenance personnel in time to ensure the safety of the instrument and the smooth development of the experiment.
