Knowledge of the Purchase of Air Compressor Accessories

Selection Knowledge

1. Discharge pressure

The higher the discharge pressure of the compressor, the more energy is consumed. The use of pressure. In general, the diameter of the gas pipeline should be larger to reduce the resistance loss and achieve the purpose of long-term operation to reduce energy consumption. The higher the exhaust pressure of the compressor, the more energy is consumed. So do not choose too high exhaust pressure of the compressor.

2. Exhaust volume

Calculate the actual total air consumption coefficient, as the choice of exhaust volume models, such as the choice of too low, can not reach the specified value of gas equipment, the choice of too large, resulting in a large energy consumption of load reduction, load reduction operation of the uneconomical. At the same time, the purchase cost of the purchase of large exhaust volume screw air compressor is higher.

3. Compressed air quality

According to the requirements of the industry air equipment for the compressor gas, should be suitable for the purchase of screw air compressor and supporting equipment. The following points should be considered. The first is to reduce the amount of oil in the compressed gas, can be used to remove oil purifier, such as high processing index, can choose multi-stage processing. The second is to reduce the water content in the compressed gas, can be used to remove water equipment supporting.

Purchase Inspection

When an air compressor has been purchased, please check the following items.

1. Check the model number of the machine ordered. Specification.
2. Whether there is any damage in the delivery process.
3. whether the documentation is complete.

If you need to buy related parts, you can choose MyMRO, we are a professional compressor parts store, we have many engines and accessories for you to choose.

Preparation Before Use

The choice of the place where the air compressor is placed.

A place with little moisture, dust, dirt, clean air and good ventilation can prolong the life of the machine and improve efficiency (for users with poor environment, such as foundries, steel mills, carpenters, cement factories and sandblasting plants, please check the filter element regularly and keep the air filter element clean). Sufficient light, easy to check and refuel. Reserve space for maintenance and place the machine as horizontally as possible, with the belt side facing the wall, but not so close as to affect the effect of the cooling fan. If the casters are removed when packing, put them back on and install the cotter pins before use.

Installation of the Prime Mover

1. When you purchase the motor for assembly, please purchase the motor matching with the air compressor.
2. When semi-automatic models are equipped with diesel engine, the output power of diesel engine should match with the rated power of air compressor.

Lubricants

Please use special lubricant for air compressor, which can effectively reduce the damage and prolong the life of the machine. You can also use other high quality air compressor oil. Please keep the oil level between the upper and lower edge of the red circle of the oil sight glass.

1. If the oil level is too low, the machine will be poorly lubricated and even burned.
2. If the oil quantity is too much, it will increase the power consumption, cause the oil temperature to rise, increase the oil consumption, accumulate carbon in the air valve, and affect the service life.
3. Pay special attention to refueling when the air compressor is stopped.
4. Please note that the quality of the oil must meet the requirements to avoid damaging the moving parts.

Checking Matters Before Operation of Air Compressor

Check whether the bolts and nuts of each part are loose and whether the belt is properly tightened. Check whether the pivot point of each wheel foot has been padded or fixed smoothly, and whether the pipeline is normal. Whether the lubricating oil surface is appropriate. Are the electric wires and electrical switches in accordance with the regulations, and are the wiring correct. Is the voltage of the power supply normal? Whether the compressor pulley can be easily turned by hand (check whether there is any abnormal sound by turning the car for several revolutions). Condensate and oil should be removed from the tank. When connecting the expansion rubber orifice quick coupling, the exhaust ball valve should be closed first and then opened after the connection is completed.
