Description

Heat Exchanger Presentation
Equipment	Liquid nirogen
Model	JR16V2000 Heat Exchanger
Heat Rejection Module	High and Low Radiator/Hydraulic Oil Cooler / Fuel Oil Cooler/Pump Oil Cooler/ Torque Oil Cooler
Engine	16V2000-R1638K39 1502HP
External Size	76.8"x78.3"x37.5" (1,950x1,990x953 mm)
Performance	With High Efficency of Heat Transfer. Compact structure, surface area can be 1000~2500m/m because of expansion of plate-fin heat exchanger with the quadratic surface Well adapted, Plate-fin heat exchanger can be applied to: gas - gas, gas-liquid and liquid-liquid. Pressure Strength Resistant Capability is high.(Max 4.0Mpa) Low temperature resistant capability is strong(Ambient Tem.-65°C) Fin lodging resistance capability is strong, easy to maintain, flush.

Installation

Be careful when lifting off , forbidden knock against.

To fix the heat exchanger on the base by installed hole, are not allowed to shake.

To guarantee fan installation and fan cover to be concentric, pay attention to suction and blowing.

Motor wiring in accordance with motor manual, pay attention to motor veer.

Tube connected to the system may not be misplaced, twisted, no to be leakage.

Not allowed to have obstruction in front and back of heat exchanger.

Operation

Conduct trial operation, to check leak or not, to check fan and cover breakage or not, to check scraping or not, to check wind direction correct or not, to check motor normal or not.

Internal medium in heat exchanger should be kept clean, no granular, floc impurities.

Outside air of heat exchanger should be maintained no weeds, batting, dust, particles, to avoid blocking.

During running, if appear much noise and resonance phenomenon, stop immediately and check.

Maintenance

Regularly check internal medium quality of heat exchanger, if there is particles, floc matter etc, need exchange in time.

Regularly check outside channel of heat exchanger, if there is any jam, need high pressure air purge.

If heat transfer performance fall largely, please stop and check.

The vibration of equipment during the operation may cause connection bolt loose. Therefore, the connection position should be checked every three months.

The equipment must be operated under design pressure, overpressure operation is forbidden.

Failure	Reason		Elimination Method
Cooling decline	Fan stop rotating		Check motor and fan cover
	The air side channel blocked		High pressure air purge
	Inner  channel  blocked		Stop and clean
Fan abnormal sound	Shaft sleeve loosen		Hammer shaft sleeve
	Bolt loosen		Tighten the bolt
	Fixed bolt of motor loosen		Tighten the bolt
Pressure increase of inlet and outlet	Inner Channel blocked		Stop  and  clean
	Thermostat  failure		Exchange  thermostat
The fan stop running	Motor stop running		Check  motor
