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

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
