Information

1. Preparation before starting

(1) Wear protective clothing such as work clothes, hard hats, gloves, and masks.

(2) Check whether the screws of each part are loose, whether there are obstacles around the motor equipment, whether there are ore or debris in the crushing cavity, and correct the tension of the belt. All spring screws must be tightened.

(3) Check whether the clearance of the ore discharge mouth is in compliance with requirements. The clearance of the PYS-D1324 conical breakout pit is kept at 30-45㎜, and the clearance of the PYS-D1608 conical breakout pit is kept at 13-15㎜.

(1) When the oil temperature is heated to 25-30 degrees, first start the oil pump motor for 5-10 minutes, check the working condition of the lubrication system, the oil pressure is 0.11-0.18Mp, observe that the oil return pipe is normal, and the oil quality meets the requirements. Start the main motor.

(2) Check that the temperature of the oil supply and return pipe of the lubrication station does not exceed 50 degrees every hour, the amount of return oil is sufficient, and the height of the oil level in the fuel tank is normal. There is no oil leakage in the lubrication pipe or the cone body of the oil pump.

(3) After the crusher is running for 1-2 minutes under no load, the belt can be opened and the ore feeding can be started. The ore feeding can be crowded. Pay attention to whether the ore feeding is normal, especially the ore with high mud content and high water content. Mine mouth.

(4) Pay attention to observe whether the chute, the crushing cavity and the hopper are blocked. Prevent non-broken objects from entering the crushing cavity. If a metal object falls into the crusher, stop it immediately and take it out.

(5) During operation, always check the thin oil lubrication system to maintain the height of the oil level in the tank, and the output oil pressure should not be lower than the rated oil pressure (0.8Kg / c㎡).

(6) Check the equipment, whether the dust water pipe and cooling water pipe are good. Always listen to whether the sound of the bevel gear of the crusher is normal, and whether the sound of the motor is normal. Observe the current of the main motor. It is not allowed to exceed the rated current. The temperature of the motor is lower than 60 ℃.

(1) When the vehicle is stopped normally, the ore feeding should be stopped first. After the ore in the crusher is completely removed, the main motor can be stopped and the oil pump motor should be stopped.

(2) After stopping, carefully check all parts of the crusher and find out that the problem is dealt with in time.

4, matters needing attention

(1) Take care to prevent the oil pressure from being too large. If the oil pressure exceeds 2 kg / cm2, it may cause injury due to splashing.

(2) During the inspection, ensure that the coupling guard is intact to prevent the coupling screws from shaking off and flying out and hurting people; to prevent the joints from spreading out when the pressure is too high and oil splashing and hurting people.
