The garbage truck body shakes, how to eliminate this kind of trouble:
After some garbage trucks are used for a period of time, garbage truck drivers will find that the vehicle body is slightly jerky, but they do not know where the problem is. "Body Shaking" is a signal that tells the owner that a problem has occurred. So, what caused the problem of body vibration? How to determine and solve common car owners?
First, found body shaking when driving
If the vehicle body is found to be slightly shaken or deflected during driving, it is generally a tire-induced failure. First of all, it may be that the tire balance is in poor condition and the owner is required to do a four-wheel alignment and dynamic balance as soon as possible.
The other situation is more serious, may be due to the deformation of the steel ring, which requires the owner to go to a professional repair shop inspection. This situation generally occurs in vehicles that have a long service life. In general, when a car is replaced with a new tire or a new steel wheel, it is necessary to balance the tire once. Otherwise, the steering wheel is prone to jitter when the weight is not even. Body shake can have an impact on driving comfort and handling.
The third situation is caused by the unbalanced deformation of the transmission shaft. Generally, this situation occurs when there are more vehicles that have collided with the chassis.
Second, the body shake at idle
Idle body shaking is a condition that many owners often encounter. If the owner of the vehicle starts or stops the vehicle without shutting down the engine, if the vehicle body is found to be jittery, it may mean that the vehicle has the following three conditions:
1, the ignition system problem
Examining the operating conditions of the spark plug, the high-voltage wire, and the ignition coil, the poor operation of the ignition system, and the poor flashover of the spark plug can also cause such failure phenomena.
Solution: Check if the spark plug has too much carbon and replace the spark plug.
2. Severe engine carbon deposit
The most common cause of car shake is excessive throttle or excessive carbon deposit in the fuel injector. When the internal carbon deposition of the engine is too much, the gasoline sprayed by the cold start injector will be greatly absorbed by the carbon deposit, resulting in the cold start of the mixture is too thin, making it difficult to start, in this case, only wait until the carbon absorption of gasoline When it is saturated, it is easy to catch the car. After the car is drawn, the gasoline absorbed on the soot will be sucked into the cylinder by the vacuum suction of the engine, and the mixture will be made rich. When the flammable mixture of the engine is diluted, it will be concentrated after the cold start. Idle jitter. The lower the temperature, the greater the amount of oil required for a cold start, and the more carbon deposition will affect the smooth start of a cold start.
Solution: Clean the oil circuit and check if the idle motor has carbon deposition.
3, oil pressure instability
If you have cleaned engine carbon deposits, washed throttles, replaced oil pads, spark plugs, etc., and you still find the body shake at idle, we recommend that you go to the 4S shop to check whether the fuel supply pressure and the intake pressure sensor are normal, if the oil supply Abnormal pressure or incorrect values ​​of the intake pressure sensor and poor working conditions can cause body shake.
Solution: Check oil pressure and replace parts if necessary.
4, engine parts aging
Vehicle jitter is also related to the engine's aging. The engine pin is actually the engine's suspension system. The engine pin is responsible for absorbing the slight jitter of the engine during operation. If there is a problem with the engine pin, these vibrations will be transmitted to the steering wheel and cab, causing jitter at idle.
Solution: Replace parts
The garbage truck sales representative reminds the garbage truck driver that the junk body shake may seem like a trivial matter. If you do not pay attention to the inspection, it will cause major faults. Therefore, once it is found that the body vibration fault should be resolved in time to prevent the problem from spreading.
The equipment is new complete equipment used in gold trade to recover gold from the gold-carrying carbon. It is suitable for desorption and electrolysis of gold-carrying carbon with different grades. The desorption is an intermixture of 1~2% sodium cyanide and 1~4% sodium hydroxide. The desorption solution is pumped to the heater by circulating pump and heated to the desired temperature. Then the solution flows downward to the bottom of desorption column, through the gold-carrying carbon in the column and upward to the top of it. During flowing, the solution strip gold from the carbon (at this stage the solution containing gold is called as pregnant solution). The pregnant solution runs out from the top of the column and into the electrolytic cell. In cell, the gold in the solution is electrically deposited in the steel wool of the cathode frame, and the rest (called as lean solution) flows back to desorption solution cell and recycled.
The gold mud containing rich gold and silver is taken out of desorption cell and transported to the separation section.
