Construction waste crusher summer maintenance measures


On-site emergency treatment of high temperature faults
(1) "Opening the pot" is one of the common faults caused by high temperature in engineering machinery. When the water temperature is too high, it is not necessary to open the water radiator cover to dissipate heat. This makes it easy to cause hot water to spray and injure people, and should be naturally cooled before replenishing water; According to the operating experience and the engineering machinery operating specifications, the operator should stop the operation immediately when the engine is “opened”. Do not turn off the flame and let the engine idle. At the same time, all the blinds are opened to increase the air flow, so that the construction waste crusher is slow under the action of the cooling fan. Slowly descends and releases a large amount of air bubbles generated by the cooling system.
When the engine is idling for a few minutes, the water temperature drops and it is no longer boiling, wrap the water radiator cover with a towel or a veil, carefully unscrew a part of the water radiator cover, release the water vapor, and make sure that the water vapor is released from the water radiator. After that, unscrew the water radiator cover all the time. During the process of unscrewing the water radiator cover, remember that the arm should not be exposed, and avoid the hot water from squirting the face.
If the engine has been turned off, start the engine quickly and make it idle; if the engine can not be started after the flameout, close the throttle and shake the crankshaft with the hand crank; if there is no hand crank, use the starter to make the piston intermittently The upper and lower reciprocating movements are performed several times, and the heat in the cylinder is dissipated by the ventilation movement of the intake and exhaust.
(2) When adding coolant, please add the same type of coolant as the water radiator. Do not add tap water at will, unless it is urgent. When adding cooling water to the water radiator, it is necessary to wait until the water temperature drops to about 70 °C before proceeding; the "gradual water injection method" should be adopted to gradually lower the temperature, and the water cannot be added too quickly, that is, the engine is idling while adding water. Slowly raise and stream with long water to ensure the safety of operators and equipment.
(3) When the brake or other parts are overheated, it is not allowed to cool down with water. This will reduce its life and performance, causing deformation or even cracking of the parts, so it must be shut down to allow it to cool naturally.
