The engine of the hydraulic mini crane is cooled by suction, so that the air passing through the radiator core can be well distributed. To ensure small size in use crane The original heat dissipation effect of the engine must ensure the integrity of heat dissipation related components:

1. Prevent hot gas backflow during use;

The filler around the radiator is called "sponge". But no sponge can replace it. Huai'an equipment displacement yes crane It is required to have good corrosion resistance, temperature resistance and poor ventilation, because its function is mainly to prevent hot gas backflow. That is, when the temperature of the cold air sucked in from the front of the radiator rises and then enters the rear of the radiator (engine compartment), it cannot return to the front of the radiator. If there is high-temperature gas flowing back to the radiator, the heat dissipation effect of the system must be reduced, which will lead to the increase of oil and water temperature, making the engine unable to work normally and causing early damage. Therefore, in the car crane During use, the inspection and maintenance of the "sponge" around the radiator should not be ignored, and the damaged parts should be replaced in time.

2. Ensure the smooth discharge of hot gas;

① The partition in the engine compartment behind the radiator shall not be removed and discarded at will, otherwise the hot gas will form a vortex during the circulation process, affecting the discharge of hot gas.

② All exhaust holes in the engine compartment must be kept unblocked, especially the engine exhaust holes and the lower guard plate of the oil pump must not be blocked, and objects must not be placed, otherwise the discharge of hot gas will be blocked. When the intake air volume decreases, the engine room temperature increases, and the intake air temperature also increases. Electrical components are damaged due to excessive temperature and premature aging.

3. Ensure the air circulation area of the heat dissipation part;

Huai'an crane rental in use crane During this period, due to air flow and various reasons, the ventilation area of the radiator core is easy to be blocked. If there is a protective net, the blockage shall be removed in time. If there is no protective net, the external pollution of the radiator should be cleaned in time according to the changes of the environment and construction conditions, otherwise the air duct will be blocked, the ventilation area will be reduced, and the heat dissipation efficiency will inevitably be reduced. It is more important to prevent the internal pollution of the radiator. During use, the antifreeze must be replaced and cleaned regularly in strict accordance with the provisions of the attached technical documents. It is not allowed to add polluted water to replace the antifreeze. If the internal liquid passage is blocked, it is difficult to check and clean. Replace the radiator only.
