The dumper's transmission sub-tank high/low shifting gear is inhaled through a double H intake valve. The operation of the dump truck 's shifting cylinder piston completes a series of passes after the synchronizer has engaged the gear's secondary synchronization. work. Because each time the gear is shifted, the synchronizer operates once, which also causes it to wear once. The synchronizer of the dump truck also has a service life. If it is not used correctly, it will lead to its early damage, resulting in the difficulty of shifting the shift position of the vehicle. What causes the damage to the sub-chassis synchronizer?

1. The clutch brake fluid of the dump truck is the start synchronizer. If the clutch pedal is depressed, and it is still stepped on, the pedal wall of the vehicle clutch will open the clutch brake control valve. After the air is compressed, it enters into the clutch brake valve, pushing the piston toward The auxiliary shaft of the transmission is in the braking gear. The piston braking surface of the dump truck rests on the end face of the brake gear, and both of them will generate friction at the same time. Therefore, at this time, the vehicle's gears of the transmission's gear shaft are all relying on the inertia to carry out cloud auto-coupling. When the brakes are generated, they will stop at a fast speed, so that the vehicle's driver can be reached. Get started quickly with the result. If He Liang's clutch brake loses its effect, and the shaft and the gear are still relying on inertial operation, this is forced into the low gear, which will cause the synchronization time of the synchronizer of the sub box to increase. It will also be less than ideal, and when the synchronizer of the dump truck has worked for a long time, it will also increase the degree of wear and tear.

2. After the damage to the cylinder seal of the shifter of the dump truck, it is caused by the live being unable to switch into the high gear and the low gear, and there will be a leak. If the leak situation is not very serious, the shift can also be reluctantly swapped in. Because of the occurrence of air leakage in the shift cylinder, the thrust of the piston will be insufficient, and the piston will drive the shift fork, shift shaft, and the backward movement of the slide gear, as well as the longer operation time, insufficient power, etc. of the synchronizer. Wait.

3. The oil level of the dump truck 's transmission is not sufficient, and its poor lubrication results in increased wear of the synchronizer.

4. The deterioration of the key oils in the vehicle transmissions has caused deterioration of the synchronizer due to poor lubrication.


Alluvial Gold Dressing Equipment

The STL water-jacketed Gold Concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.

The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.
