Not hammer impact, the impact to what is the reason?
Please note there is a phenomenon, is when we check with the bond rupture, gear and shaft, gear shaft and friction due to the strong glue together, not easy to find fault with the key, but the load will not work. Before changing the parts, be sure to clean up the stolen goods and oil in the trouble spots so that we can find other faults. The middle roller bearing cover must be good, such as the use of defective goods, he can be damaged, the joint will a wheel and the rotor shaft are easy to damage.
If the above conditions are normal, there is no shock, then we must observe the large cylinder to see if there are cracks, cracks need to be replaced.If the motor is switched on after starting, the hammerhead can not hear the compressed sound. It may be broken or eccentric. Such as after the turn on the motor, the hammer does not turn, there is no compression sound, there may be a wheel damage or rotor shaft broken. Another is that the umbrella tooth is bad and can not move at all.
Not to shock and shock is one of the most common fault electric mechanical parts, the main reason is the piston hammer on the apron and aging, large cylinder vertical, down mouth, such as hammer free fall, the ring must be aging. Rubber aging can hear the piston and hammer collide in the work of the voice can be found after disassemble the piston and hammer face shiny, shock can be caused by short seed impact (which can be compared to the impact of new seed oil) may also be caused by the impact of weak.
