The crusher is an important part of the excavator, and it is an indispensable component for the demolition industry. Its existence greatly reduces the work pressure of the demolition personnel. In the past, demolition requires everyone to take a hammer and a shovel. Hands-on, now only need to operate the machine is completely enough, but although it is convenient to use, there are several aspects that need to be paid attention to. The editor will briefly introduce these aspects for everyone.
1. Before starting the pulverizer, check whether the high-pressure pipe joints and nuts connected between the oil cylinder and the pump station are tightened to avoid the pliers body falling off and hurting people. When the construction is suspended, do not disassemble the connecting hose. Before maintenance and construction, first clean the joints before installing to prevent dust from entering the hydraulic circuit and causing damage to the hydraulic circuit and hydraulic components in the hydraulic system.
2. Before starting the oil pump, check whether the oil level is above the middle line of the oil mark. If there is a shortage of oil, replenish it in time to prevent the oil pump from being emptied. When refueling, use a 120 filter to filter out impurities in the oil. Clean the oil filter once a month, clean the oil tank once every three months and replace with new oil; before starting the motor, the manual reversing valve should be placed in the middle position to avoid The oil pump starts with load. Lightly jog the motor several times, and then turn the reversing valve to supply oil to the system after the pump sucks oil normally. The hydraulic oil commonly used in pump stations is YB-N32. If the ambient temperature is lower than 10°C, you need to switch to YB-N22; if the ambient temperature is higher than 40°C, you need to switch to YB-N46.
3. The pump should be overhauled once every six months. All the accessories on the pump need to be cleaned with kerosene. Pay attention to the protection of the mating surfaces and avoid any bumps. After assembly, the moving parts should move flexibly without local jamming.

4. High-pressure oil pipes will age after long-term use and should be checked frequently. In the high-pressure experiment, if there is a leaking bump or blasting, it needs to be replaced in time. Secondly, when the high-pressure tubing is in use, avoid bending or sharp bends, and not too close to the hose to prevent personal injury due to blasting.

5. Before moving the equipment, check whether the handle is moving and the ring connection is reliable. During construction, there must be sufficient working space to prevent injury or damage to the equipment.
The above are a few issues that need to be paid attention to during the use of the crushing tongs. Everything has two-sidedness. While liberating the labor force, it will also cause personal injury due to minor problems. Therefore, various inspections before starting the machine must be indispensable. of.
