Used cutting machine or cutting machine manufacturers should all know, the cutting machine can be divided into 8-500 tons according to the size of the pressure in the model, the range can meet the demand of any of the social production, through the automatic feed cutting machine of professional people understand that theory can produce any type of mechanical pressure, but according to use purpose can know, generally nonmetallic cutting industry only need 300 tons of the machinery can!
What factors determine the pressure change of the cutting machine?
Systemic stress is also a determining factor
System pressure is the motor driven oil pump output rated pressure, the higher the output rated pressure, the greater the machine pressure, but this type of hydraulic pump has long been standardized, medium pressure hydraulic pump output pressure is generally around 200 kg.
The pressure is too high, its supporting hydraulic actuators, pipes, joints and other components of the cost will increase exponentially its technical difficulties will double. Know that both of the above items is an important factor decided to machine the size of the pressure, we haven't enough in pressure machine, or a machine without pressure when they know where to check, maintenance machine will be a great help of analysis: it is important to note: in the practical maintenance, we should also consider executive components such as the degree of pipe sealing, leaks, seal is damaged factors such as comprehensive analysis; Only in this way can the root of the fault be quickly and thoroughly eliminated.
The size of the oil cylinder is one of the decisive factors
Under the condition that the output pressure of the oil pump remains unchanged, the larger the oil cylinder, the greater the pressure generated by the machine will be, which is why the large pressure machine cylinder is larger than the small pressure machine cylinder.
Note: the size of the oil cylinder is not the size of the head, but the diameter of the piston of the oil cylinder.
