How to regulate the air pressure of the truck exhaust valve, kneel and beg How to adjust the air pre

The system air pressure of the whole vehicle is through the pressure regulator valve of the dryer.

Regulation is decided. When the air pressure is charged to the exhaust pressure set by the dryer, a loud exhaust sound will be heard, and a water mist will be sprayed out. Adjusting the regulator of the dryer is sufficient.

When there is a gas overflow in the system, the gas will climb up along the pipeline, and finally gather at the highest point of the system, and the exhaust valve is generally installed at the highest point of the system, when the gas enters the valve cavity of the exhaust valve and gathers in the upper part of the exhaust valve, with the increase of gas in the valve, the pressure rises, when the gas pressure is greater than the system pressure, the gas will make the water surface in the cavity fall, and the pontoon will fall with the water level and open the exhaust port;

Method: There is a distribution valve on the side of the gas storage barrel, there is a screw above or below the distribution valve, you need to change the cone and the wrench at the same time, loosen the screw with a wrench, turn half a circle counterclockwise with the change cone, and then lock the screw, turn off the ignition immediately if the air pressure is too large, and step on the brake a few times to do not let the air pressure be greater than 8.

If the wrong air pressure is too large, it may cause the gas tank to burst open, it is recommended that two people operate it and try it slowly.

Common faults of trucks.

First, the clutch is trembling.

Clutch trembling refers to the phenomenon that the clutch is not smoothly engaged when the car starts, causing the vehicle to shake. The clutch trembles, which will not only affect the normal start of the vehicle, but also damage the mechanical parts in serious cases.

The main causes of clutch tremor are as follows:

1. The height of the inner end of the separation jaw is inconsistent.

2. The fixing bolts of the clutch housing and flywheel housing are loose.

3. The engine fixing bolt is loose and the bracket is broken.

4. The rivet of the clutch driven disc is exposed and touches the pressure plate.

5. The driven disc is warped and deformed.

6. The clutch pressure plate is warped and deformed, and the spring elasticity is insufficient.

7. The spline groove of the driven disc hub and the spline teeth of the first shaft of the transmission are too large due to wear.

8. The front and rear supports of the engine are damaged.

Second, the clutch slips.

The vehicle cannot start or has difficulty starting, acceleration cannot be added, and when it is serious, it emits a burning odor, which is clutch slippage.

There are several reasons for clutch slippage:

1. The free stroke of the clutch is too small, the release bearing is pressed on the inner end of the release lever, and the pressure plate is in a semi-separated state, which slips when transmitting power.

2. Improper operation of the driver. The uphill shift is not timely, and the engine is about to turn off before switching into a low gear; When starting the engine again, first hang up the high gear, and then use the method of relaxing the clutch pedal to force the engine to start; The slip grinding of the clutch friction plate is aggravated.

3. The clutch pressure plate spring is broken, which greatly reduces the ability to transmit engine torque, resulting in slippage.

4. The clutch friction plate becomes thinner after wearing, the surface is hardened, and the rivet is exposed or stained with oil is also the reason for the clutch to slip.

5. Improper adjustment of the clutch release lever and loose bolts of the clutch and flywheel will also cause the clutch to slip.

There is a distribution valve on the side of the gas storage barrel, there is a screw above or below the distribution valve, you need to change the cone and the wrench at the same time, adjust to it is very good to adjust, it will not be adjusted that is quite dangerous, if the wrong air pressure is too large to close the collision may cause the gas reservoir to burst open, the method is to loosen the screw with a wrench, turn half a circle counterclockwise with the change of mind, and then tighten the lock screw, ignite and find that the air pressure is too large and immediately turn off, step on the brake a few times do not let the air pressure be greater than 8.

<> truck boiler has two exhaust valves, one under the gas reservoir; The other is below the air drying tank assembly. A lorry is a commercial vehicle designed and equipped primarily for the purpose of carrying goods, whether it can tow a trailer or not. Trucks are generally called trucks, also known as trucks, which refer to automobiles that are mainly used to transport goods, and sometimes also refer to automobiles that can tow other vehicles, and belong to the category of commercial vehicles.

Generally, it can be divided into two types: heavy and light according to the weight of the car. The vast majority of vehicles are powered by diesel engines**, but some light goods vehicles run on petrol, liquefied petroleum gas or natural gas. A vehicle is usually composed of four parts: engine, chassis, body, and electrical equipment.

Summary. Hello, for your question [how to adjust the truck J6L air pressure regulator] This question is answered as follows: Truck air pressure valve adjustment method:

Close the downstream valve of the pressure reducing valve, find the position to adjust the pressure, rotate clockwise, increase the outlet pressure, rotate counterclockwise, and decrease the outlet pressure.

Hello, for your question [how to adjust the truck J6L air pressure regulator] This question is answered as follows: The truck air pressure valve is adjusted by the downstream valve: close the downstream valve of the pressure reducing valve, find the position of the adjustment pressure, rotate clockwise, increase the outlet pressure, rotate counterclockwise, and reduce the outlet pressure.

Hello dear dear This is the relevance I found for you with such a talk: after finding the air pressure regulating valve, do not stupidly touch the oak section directly, first observe the barometer, and ensure that the air pressure does not exceed 6 pressure values. Because for beginners, if they don't know how to adjust the pressure, they are prone to too much pressure, and the gas storage barrel is very dangerous.

After the preparation is completed, use a wrench to clamp the tuning screw of the air pressure regulator and rotate the adjusting screw of the air pressure regulator inward 1 turn clockwise, and the exhaust pressure of the system rises by 1. Rotate the adjusting screw of the gas pressure regulator counterclockwise to observe 1 turn in advance, and the system exhaust pressure rises by 1. The general air pressure is 8 air pressure when leaving the factory.

Test the internal air pressure. The shift is usually 9 atm. According to the pressure gauge, turn the wrench to adjust to the air pressure specified by the system.

Due to the large weight of the truck, the brake square Qifan type chosen when braking is air brake. The main components are air pumps, dryers, air pressure regulators, four-way valves, gas cylinders, foot brake valves, hand brake valves, relay valves, quick replacement valves, brake booster pumps, etc. The number of hail pressures in trucks' high cavities is usually maintained at 9 atmospheres to prevent daily brake lock-up or brake failure.

There should be a small nut on the upper section of the unloading valve, that is, the exhaust valve, and the top of the nut is a small screw that can be screwed with a flat taper, loosen the nut and screw the middle screw down a few times, of course, to ensure that it is in the range of about eight air pressures.

There's an adjusted half-turn on the drying tank, and it's OK, and the first little cylinder that comes out of the air pump sits on it, and let's look for it.
