In order to reduce the damage of compressor parts and extend the service life of the compressor, daily protection and maintenance are extremely important and necessary. The daily maintenance work mainly includes: regularly lubricating and oil changing the equipment, anticorrosive operation of the equipment, and regularly correcting the accuracy of the equipment. under.

Most factories and enterprises using hydrogen compressors need to use this equipment separately from other gas-using equipment, and when the pressure of the equipment is lacking, it will affect the normal operation of other gas-consuming equipment. Therefore, if the staff controlling the hydrogen compressor finds a lack of pressure, they must first check their own gas consumption. After discovering that their gas consumption has increased, they should increase the number of air compressors or replace high-power air compressors. deal with.

In principle, the lubrication parts of carbon dioxide compressors can be divided into two categories. One of them is internal parts that are directly touched by oil and condensed gas, such as cylinders, pistons, piston rings, piston rods, exhaust valves, sealing packing, etc .; rotary compression. Air cavity, rotor (rotating body), exhaust valve, etc.

The gas phase of the secondary outlet of the BOG compressor returns to the imported flash tank D ~ 2, and the control circuit part of the valve PV-2 is controlled by the pressure P-2 of D-2. Here, the setting value of P-2 is 300KPa. If the pressure of D-2 is higher than this value, valve PV-2 is closed. If the pressure of D-2 is lower than this value, valve PV-2 is opened to return the gas phase.

When the compressor is started, the current of the motor will be 5-6 times higher than the rated current, which will not only affect the service life of the motor and consume more power. The system will leave a certain margin in the motor selection during the design. The speed of the motor is fixed, but in actual use, sometimes it needs to run at a lower or higher speed, so it is necessary to carry out frequency conversion transformation. The inverter can achieve the purpose of soft starting the motor, changing the input voltage frequency of the equipment to achieve energy saving and speed regulation, and can provide equipment with overcurrent, overvoltage, overload and other maintenance functions.

Ammonia compressors have a wide range of applications. They are suitable for boosting, stabilizing, powering and purging in industrial use. They can also provide stable power sources for power plants, food industries, pharmaceuticals and experimental research units.

Mainly used in chemical industry waste gas recovery, pressurization and other process operations. The advantage is that the working pressure range is large. Different types of pumps can be used to obtain different pressure ranges. The input air pressure and output air pressure can be adjusted accordingly to achieve extremely high pressures. The flow range is wide, and all models can work smoothly under normal air pressure. At this time, the flow rate obtained at this time can be adjusted to obtain different flow rates.

2. The general operation of the pipeline will inevitably cause some foreign matter or dirt in it, and the general pipeline has a pig to clean the pipeline, but sometimes the pipe jamming problem may also occur, then the transportation efficiency of natural gas in the pipeline will be reduced. Even in the case of stagnation, at this time, the use of natural gas compressors to provide pressure can quickly pressurize and forcibly clear the jam.

Turn on the first time, and the time should not exceed 30 seconds. If the oil pressure gauge does not move, turn it on again. If the oil pressure gauge still does not move after repeated 5-6 times, the oil gauge may be damaged or blocked, and clear Fill the oil circuit or inward from the oil gauge hole.

1. The main reason for the failure of the exhaust volume may be valve leakage, packing leakage and excessive cylinder clearance. Check these places at this time and take corresponding measures.
