The pressure cylinder gas-liquid pressurized press often operates at high speed, easy to cause the machine wear, it should be according to the operation instructions for operation, pressurized cylinder working temperature at -5 degrees ~60 degrees Celsius, the operation speed of 50~1000mm/s, in order to ensure the normal operation of the pressure cylinder, the following points should be noted in the use of: 1. keep clean in the booster the gas cylinder access path, please be piping and components inside the dust and other debris removal, so as not to reduce the service life of the pressure cylinder. 2. the use of normal pressure range, the cylinder in normal use, the work pressure must be in accordance with the inspection report specified in the work range of pressure, shall not exceed the required working pressure. 3. pay attention to the working environment of the pressure cylinder. When the cylinder is designed, the temperature in the working environment has been fixed. If the work environment needs to be changed, the working environment should be contacted with the related personnel of the booster cylinder. As part of the cylinder component is iron, so please do not use it under the environmental conditions for complex environment (such as exposure to environmental chemicals), please air handling units installed in the front cylinder effective (three points) and joint lubrication and drainage treatment. 4. not tampering with other hydraulic oil. The hydraulic oil price used in the design of pressurized cylinder is VG68# anti-wear hydraulic oil. It can not be withdrawn and replaced with other liquid medium (such as oil, water, etc.). 5. be sure to follow the program. Action procedures must be in accordance with the gas line fitted with the action program, that is, pre pressing action - pressurization action, pressurization, pressure release - pre pressure reset. 6., pay attention to maintenance, often check the pressure cylinder operation. To avoid excessive pressure on the cylinder during pressurization, damage to your mold or workpiece, please install a pressure reducing valve at the inlet of the booster section so as to effectively protect your product. In order to ensure the stability of the pressure cylinder, it is recommended to install a gas pump in parallel between the triple parts and the booster cylinder as much as possible. The use of more than 500000 cylinders or more than half a year, it is recommended to replace the hydraulic cylinder once, in order to improve the service life and service life of the cylinder.
