How to Start a Reciprocating Compressor

You can separate air compressors into two categories: positive displacement and dynamic displacement. The reciprocating air compressor is a positive-displacement compressor that uses a crankshaft-driven piston and cylinder to compress air. This compressor is often used in applications where large volumes of high-pressure air are needed, like in a paint booth. They are available in different sizes and power levels to suit the application’s specific needs.

Before Starting the Reciprocating Compressor

For a smooth and trouble-free operation, you need to check the compressor before starting. Check filters, lubricants, and coolants.

Other specific things you need to do before starting a reciprocating air compressor include:

Reading the User Manual        

Is it your first time using the machine? Go through the user manual first. Different companies have different designs and models of reciprocating compressors.

You need to understand the instructions from the manufacturer before handling the compressor.

Checking the Oil Levels

The oil levels should be above the minimum mark on the sight glass. Always ensure the oil is at its required level before using the compressor.

Checking the Cooling-Water Supply Valves

Ensure that the cooling-water supply valves are open before starting the compressor. Reciprocating compressors generate a lot of heat. They need to be cooled continuously to prevent damage to the machine.

Ensuring the Voltage Circuits Are Operable

Before starting the machine, ensure that all voltage circuits are in good working condition. A problem in any voltage circuit can cause the compressor to malfunction.

Starting a Reciprocating Air Compressor

Starting a compressor is not difficult if you follow the right procedure. Depending on the model and make, the starting procedure of a compressor can vary.

However, there are general steps that are followed in all models:

• Meet the interlock requirements of the system

All interlock requirements need to be met before starting a reciprocating compressor. The system is designed to prevent the compressor from starting under certain conditions. This interlock system regulates pressure, temperature, voltage, and oil level.

• Switch on all the heaters

Once the interlock system requirements have been satisfied, switch on all the heaters. A compressor has several heaters, such as the motor space heater and oil heaters. These heaters help bring the machine’s temperature up to the required level before starting.

• Get permission to start

The next step is to get permission to start the compressor from the system control room. A compressor system control room monitors all the parameters of the compressor. Once they permit you to start, you can proceed to the next step.

What Makes a Compressor Not Start?

A compressor can immediately and automatically shut down after starting. This is because the safety devices in the compressor have been activated due to certain conditions.

Some of the reasons why a compressor may not start include:

Overheating

Compressors usually overheat if the cooling system is damaged. As a result, it will automatically shut down.

Oil Pressure

The oil pressure must be within the specified range. If it is not, the machine will automatically shut down.

High Discharge Pressure

When the discharge pressure of the reciprocating air compressor is high, the machine will automatically shut down.

Too Much Suction Pressure

If the machine’s suction pressure is high, it will automatically shut down.

Key Takeaways

Many industries use reciprocating air compressors. They are reliable and efficient. Checking the oil level, cooling-water supply, and voltage circuits is important when starting.
