Precautions when using pulverizer

Crushing tongs is a kind of equipment used with excavators. It has the characteristics of simple operation, high work efficiency, and mechanized operation. However, even with many advantages, there are still many things that need to be paid attention to when using it. This is to make the equipment work better. , But also to extend the service life of the equipment. Let me take a look at these precautions together.

1. If the high-pressure oil pipe is used for a long time, it will be aging, so it needs to be checked regularly. Once any problem is found, it needs to take immediate measures. Moreover, in the process of using the high-pressure oil pipe, it is necessary to prevent discounts or sharp bends, and not too close to the hose, otherwise there will be blasting and injury.

2. Before the pulverizer motor is started, the manual reversing valve (three-position four-way valve) should be in the middle position (the oil does not enter the cylinder but directly into the tank) to prevent the oil pump from starting with load. Start the motor several times, and then turn the reversing valve to supply oil to the system when the pump sucks oil normally.

3. For objects that are not easily crushed, they can be crushed and peeled point by point from the edge to the inside, looking for weak points, and breaking them individually.

4. Before handling the crushing tongs, check whether the handle is moving and whether the ring connection is reliable. During the construction, there must be sufficient working space to prevent casualties or damage to the equipment.

5. During the crushing operation, it is necessary to check the vibration amplitude of the hose from time to time. If the vibration is severe, stop the operation and check whether the hydraulic pressure is stable.

6. Do not use the method of impact during the use of the pulverizer, as this will damage the main body of the pulverizer or break the connecting shaft.

7. Before starting the oil pump of the pulverizer, check the oil level to see if the oil level is above the center line. If there is a shortage of oil, you need to replenish the equipment before turning on the equipment to prevent the oil pump from sucking.

8. Do not clamp objects that exceed the load of the crushing tongs, which will cause damage to the equipment.

9. The anti-rust work of the equipment is very important, and the application of anti-rust oil must not be omitted.

10. Check the opening and closing regularly. When the distance is too large, check the upper and lower clamps and their gaps and make adjustments in time.

11. The oil cylinder needs to keep a certain distance from the reinforced hard objects to prevent external damage to the piston rod and at the same time prevent the oil cylinder from being strained.

12. Before using the crushing tongs, it is necessary to check whether the high-pressure pipe joints and nuts connecting the oil cylinder and the pump station are tightened to prevent them from falling off and hurting people.

13. The storage work after the crushing tongs are used up is also very important. In order to prevent rainwater from entering during storage, the rear cylinder should be raised on one side and stored in a room with low humidity.

14. The normal working temperature of the hydraulic system is 20-50℃. If the temperature is too high, cooling measures are needed. When the oil temperature is too low, heating measures are needed. You can also increase the oil temperature by idling the oil pump without load. .

15. The pump needs to be overhauled once every six months. All accessories need to be cleaned with kerosene, and the surface of the accessories should be protected. They should not be bumped at will. After assembly, the moving parts should run flexibly without local jamming.
