The causes and solutions? Too low or too high pressure of China cnc plasma cutting machine sale
Jinan Dekcel Cnc Equipment Company has many types of good quality plasma cutting machine for your work. As a China plasma cnc machine manufacturer, it is our honor for service plasma cnc cutter users. And our company can also provide technical service for you. This article we will introduce the causes and solutions of too low and too high pressure of cnc plasma cutting machine.
1. Too low pressure: whencheap cnc plasma cutter machine working, such as pressure is much lower than the pressure instructions required, which means that the plasma arc jet velocity decreases, the input air volume is less than the specified value. So The good price plasma cutter cnc can’t form plasma arc with a high energy and high speed, resulting in poor quality of cutting. The reasons for the lack of air pressure are: the air compressor input air is insufficient, the plasma cutting machine air valve adjustment pressure is too low, there is oil in the solenoid valve, gas road is not smooth, etc..
Solution: before using high speed plasma cutting cnc machine, the users of cnc plasma cutter should pay attention to the compressor output pressure display. If the pressure does not meet the requirements, the Huayuan 100A plasma cutter used can adjust the pressure or overhaul air compressor. If the input pressure has reached the requirements, customers should check air filter relief pressure valve regulation is correct, if the gauge show can meet the cutting requirements. Otherwise, the part shall be regularly maintained to ensure that the input air is dry and oil-free. If the quality of input air is poor, it will cause oil pollution. In addition, the torch nozzle pressure is too low, you also need to change the electromagnetic valve. And the gas path section smaller can also cause the pressure is too low. Customers can be replaced gas according to the instructions.
2. Too high pressure : if the input air pressure is much more than 0.45MPa, after the formation of plasma arc, too large air flow will blow out the concentrated arc column.So that the energy of the arc column is dispersed, and the cutting strength of the plasma arc is weakened. Causes of excessive air pressure are: improper input air conditioning, pressure relief valve regulation is too high, or air filter pressure reducing valve failure.
Solution: check if the air compressor is adjusted properly, air compressor and air filter pressure relief valve is misalignment. After startup, such as rotating air filter valve switch, no change of voltmeter. That is show the air filter relief pressure valve failure to replace.
