Complete Guide to the 1033ZAX360 Hydraulic Pump: Everything You Need to Know

When the battery liquid specific gravity is lower than 1.15 or the single cell voltage is lower than 1.7V (V), or when changing seasons for maintenance, it should be removed for recharging and the liquid specific gravity should be adjusted. If it needs to be parked for a long time, it should be fully charged and stored, and recharged once a month. If it needs to be stored for a long time, it should be fully charged, all the liquid should be poured out, and the filling port should be sealed for storage. When it needs to be used, re-add the electrolyte that meets the requirements.

1. Chain off caused by tension cylinder failure
At this time, you should check whether you have forgotten to butter the tension cylinder and see if there is any oil leakage in the tension cylinder.

2. Chain off caused by severe wear of the crawler
If used for a long time, the crawler will definitely be worn, and the wear of the chain ribs, chain barrels and other parts on the crawler will also cause the crawler chain off.

3. Chain off caused by wear of the chain guard
Now almost all excavator crawlers have chain guards, and chain guards can play a very important role in preventing chain off, so it is also very important to check whether the chain guard is worn.

4. Chain off caused by wear of the drive motor ring gear
For the drive motor ring gear, if it is severely worn, we need to replace it, which is also an important reason for the excavator chain off.

5. Chain off caused by damage to the sprocket wheel
Generally speaking, oil leakage of the sprocket wheel oil seal of the excavator will cause severe wear of the sprocket wheel, which will cause the crawler chain off. The public account Zhizao Daguan focuses on sharing relevant theoretical knowledge in the engineering machinery manufacturing industry.

6. Chain derailment caused by guide wheel damage
When checking the track guide wheel, check whether the screws on the guide wheel are missing or broken. Check whether the groove of the guide wheel is deformed.

Testing engine performance includes checking the engine's start-up, running, acceleration, and emissions. Use diagnostic equipment to read engine fault codes, test the fuel system and ignition system, and regularly conduct compression tests and exhaust analysis.

1. The starter and flywheel teeth are not meshed well. The ring gear and the starter gear collide when starting the engine, causing tooth damage or single-sided wear of the teeth. If more than three teeth are damaged or worn seriously, it will be difficult for the starter gear and the ring gear to mesh.

2. Cylinder sticking. When the engine temperature is too high, the engine is stopped and the heat is difficult to dissipate. The piston ring at high temperature sticks to the cylinder and cannot start after cooling.

3. Crankshaft lock. Due to lubrication system failure or lack of oil, the sliding bearing rubs dry, which eventually locks the crankshaft and cannot start.

4. The injection pump plunger is stuck.

1. There must be enough starting speed. The high starting speed means less gas leakage in the cylinder, shorter heat transfer time of compressed air to the cylinder wall, less heat loss, and higher gas temperature and pressure at the end of compression. Generally, the speed is required to be above 100r/min.

2. The cylinder should have good sealing. This can further reduce the amount of leakage and ensure that the gas has sufficient combustion temperature and pressure at the end of compression. The compression pressure of the cylinder shall not be lower than 8_0_%_ of the standard value.

3. The engine is required to have appropriate clearance relative to the running parts and good lubrication.

4. The battery must have sufficient starting capacity and the technical condition of the starting circuit is normal.

5. The starting oil volume meets the requirements, the injection quality is good, and the injection advance angle meets the requirements.

6. Use fuel that meets the requirements
