Or maintenance cost height but poor reliability, so failing to be popularized always.
Because there is above-mentioned technical problem in electronic oil cutting-off device, widely used a kind of oil-break on anti-explosion diesel engine at present
Device is pneumatic oil cutting-off device.Due to no electric component, it is not necessary to consider the technical factor of electrical explosion proof, so, pneumatic oil-break
Device solves the temperature rise of electronic oil cutting-off device, flame proof, bulky and reliability technical problem.But pneumatic oil cutting-off device
It must install additional to provide the devices such as the air compressor machine, air accumulator and control valve of source of the gas；And pneumatic oil cutting-off device is not easy reality
The automation mechanized operation of existing diesel engine, if automatically controlled because to realize, it is necessary to install the gas of explosion-proof Electromagnetic Control additional
Body valve；In addition, Pneumatic pipe is more more complicated than automatically controlled circuit, the technology difficulty of construction is much bigger, and manufacturing cost is also significantly larger than
Electric-control system.
