There may be many friends who experience high-speed oscillation when using a docking garbage truck. In order to solve this problem, we must first find out what caused the cause of the failure and know the reasons for exclusion and finally solve the problem.
There are six reasons for the high-speed swing of the docked garbage truck.
1 The front wheel alignment angle of the garbage truck is misaligned, causing the front bundle to be too large;
2 The imbalance of the front tire pressure of the garbage truck is too low or the tire is caused by repairs or other reasons;
3 The front spoke deformation or the number of tire bolts are not equal;
4 loose parts of the drive system components;
5 garbage truck drive shaft bending, dynamic imbalance, front axle deformation;
6 Vibration absorber failure, inconsistent rigidity of the front leaf spring; deformation of the frame, loosening of the rivets, or deformation of the front shaft.
Butt-type garbage trucks at high speed vibration diagnosis and troubleshooting:
1 There are usually two cases of high-speed runout. One is that as the speed of the garbage truck increases, the oscillating movement becomes stronger; the other is that during a certain period of high vehicle speed, the oscillates and causes the steering wheel to shake. In making judgments, the drive axle is first erected, the front wheel is plugged with a safety plug, the engine is started and the high speed gear is gradually changed, so that the drive wheel reaches the final test-pivoting speed. If both the vehicle body and the steering wheel appear to shake, this is the vibration caused by the garbage truck drive system. Because the front axle front axle is at a standstill at this time, if the final trial oscillation speed is reached and the garbage truck does not appear to shake, the reason for the vibration is that there is a fault in the front axle part of the garbage truck.
2 Check whether the front wheel alignment angle and the front wheel meet the requirements. If the misalignment should be adjusted immediately.
3 Set up the front axle to test the wheels, check the wheel static balance and whether the tire is deformed too much. If necessary, carry out comparative tests of good docking garbage truck wheels.
Through the above introduction, I believe that everyone has a certain understanding of how to solve the high-speed swing failure of the docking garbage truck, clear the cause of the failure, and master the elimination method, I believe that this type of failure can be easily handled again. I hope my sharing can help you.
Gamma 99% Purity Medical Oxygen Generator is used to produce oxygen with purity up to 99%. It is the combination of standard 93% purity Oxygen Generator with one oxygen purifier. Detailed parts combination is as below:
Air Compressor
Function: provide compressed air source for the PSA oxygen generator, the flow and pressure are to be decided by the desired oxygen flow rate, purity, outlet pressure. As it is the air source of whole system, the performance of air compressor has remarkable influence to the whole oxygen generator system. Air source must be stable, sufficient with pressure not less than 7.5 bars.
Compressed air treatment part
Function: get rid of water, oil, impurities in compressed air coming from the air compressor, providing clean, dry, oil-free compressed air for the PSA oxygen generation part. It includes 3 filters, 1 refrigerated dryer and 1 activated carbon oil remover. After treatment, dew point of compressed air can reach -20 degree (normal pressure) , dust content is not larger than 0.01mg/m3, solid particles diameter is not larger than 0.01μ, oil mist content is not more than 0.003mg/m3.
Air tank
Air tank function:
It quickly increases the pressure of adsorber;
It also stores gas for air compressor, buffers system pressure;
PSA oxygen generation partFunction:
It is the key part of whole system. In this part, the oxygen is separated from compressed air, sent to buffer tank as produced gas. Nitrogen, carbon dioxide, argon,etc are discharge from muffler as exhausted gases. The efficiency of this machine is mainly decided by adsorption tower structure, air distribution structure, molecular molecular sieve performance, process flow, etc.
O2 buffer tankO2 buffer tank function:
It balances pressure fluctuation, ensure stable oxygen supply;
With oxygen re-blowing system, the O2 buffer tank can also quickly increases the pressure of adsorption towers.
PSA oxygen storage tank 1Function:
To help the performance of oxygen purifier, one oxygen storage tank is supplied.
Oxygen purifierFunction:
This is another key part for the high purity oxygen generator. After its treatment, 99% purity oxygen is achieved.
Oxygen storage tank 2
Function:
After treatment of oxygen purifier, the 98% purity oxygen has very low pressure, for getting higher pressure, another oxygen storage tank is supplied.
Oxygen CompressorFunction:
As the 99% purity oxygen pressure is very slow, to get 150 bars pressure, one oxygen compressor is needed.
Oxygen filling station
Function
It is used to fill the high pressure oxygen into cylinders for storage or selling.
High purity Medical Oxygen Generator specification:
Oxygen purity: 99%
Oxygen flow rate: 5-100 Nm3/Hr
Oxygen outlet perssure: 5-200 bars99% Purity Medical Oxygen Generator
99% Purity Medical Oxygen Generator,Hospital Oxygen Generators,Cylinder Filling Oxygen Generators
