Placement of Installation and Intake Air

Install the compressor possibly nearest to the site of service. If site of service lines scattered, install the compressor collectively around the center of lead to minimize piping resistance and leakage and save the cost of installation.

Also Please note that well lighted space helps you find earlier leakage and abnormal as well as perform maintenance service smoothly, while Quiet environment enables to detect even a slight abnormal sound, preventing possible troubles.

Ample passage provides and facilities security, disassembly work and maintenance and inspection. At least, space of 1 meter should be reserved around the compressor. In most cases air intake includes dust. It is known by analysis that half of the carbon deposit on the valve is dust. These faulty conditions would cause leakage from cylinder or piston, or malfunction of valve, finally efficiency down and great troubles.

Air Delivery Piping

High temperature rise in delivery pipe line would cause thermal expansion. Therefore, piping should be installed in such a manner that it can absorb contraction or expansion.

(1) For this purpose, the use of more than two bends on the midway of pipe line is recommended. Where one piping section is so long, the pipes should be supported with appropriate pipe supports.

(2) Arrange delivery pipe as short as possible.

(3) Stop-valve should not be installed in the midway of delivery pipe. If it is needed to be done, safety valve must be fitted between the compressor and the stop valve. Safety valve used for this purpose should be large enough to release all the Compressed air.

Electric Wiring

Wiring must be installed correctly by qualified engineers or contractors in conformity with applicable codes. Durability and insulation tests should be done carefully while tools and materials used in wiring must meet the requirements of standards. Electrical Motor starting method should be selected according to power facilities of the plant. For details, consult with contractor or our firm.
