Q:How is the main oil circuit of the automatic transmission valve body produced?

After the engine starts, the crankshaft drives the pump wheel to rotate, and the centrifugal force generated by the rotation causes the impeller of the pump wheel to rotate between the blades

Q:There is body oil, there is that friend know the notification.Volkswagen Lang Yi DSG what gear oil is better, as well as body oil, there is that friend know the notification

This last 4S shop, ah, DSG warranty for 10 years, a problem, the general master dare not move

Q:2012 MAGOTAN 1.8T gearbox oil to the oil inside the body what consequences

No, the body oil and transmission oil is different, transmission oil is gear oil, body oil is dedicated, green oil, much less than the transmission oil

Q:The high pressure steam pipeline gate valve, valve packing at both sides of why there are two symmetrical small hole ah?

The water goes into the filling and fills the little hole, so that the gas in the pipe doesn't run out. It's a way to strengthen the sealing effect.

Q:What do you mean by shot blasting on the surface of valve body?

Its main function is: 1, 2, rust removing sand; rust; 3, the removal of the surface of the die casting stress. The iron molecular workpiece surface more compact, improve the surface quality;

Q:SIEMENS thermostat valve actuator corresponds to the pipe diameter

The actuator and valve diameter is set according to the schedule, the water valve and steam valve stroke is different, according to the type and caliber optional valve actuators, such as SIEMENS VVF40 series, DN25~DN80 SAX61.03, stroke 20mm, SKD60/62, SKB60/62, DN100~DN150, travel 40mm, available SKC60/62. so we should according to the actual use of the environment selection

Q:Body material is CF8 (P), what is the material?

CF8 is the CF8=304 of 304 stainless steel304 casting is called CF8The 304 forging is called F3043 and 8, the two numbers represent carbon content, 0.03 and 0.08, respectively0.03 corresponds to L (low, carbon, low carbon)The letter "M" stands for 316 stainless steel and contains molybdenumIn this way, distinguish between the four kinds of cast steel code.

Q:When the valve and pipe welding connection, why welding machine ground is strictly prohibited on the valve body?

It fires, or fires by a very large current. There may be too high temperature will damage the body sealing material, if it is high temperature and high pressure valve, you put the FireWire on the valve body, it will cause damage to the valve body, it may shorten the service life of the valve body.

Q:Lang Yi double clutch body oil how to add?

Oil change method:1. Run the engine so that it reaches the working temperature. Then the vehicle up with Jack, pull the hand brake and the front wheel with wedge squeeze.2. Place the old oil container under the oil pan, find the oil drain bolt of the oil pan, and slowly open the oil bolt. Be careful not to touch the hot oil. Let the oil drip for a while. Check the oil drain bolts and re install the oil drain bolts. Be careful not to screw the bolts too tight to prevent damage to the oil pan.3. Transfer the oil container to the oil filter. Use the oil filter wrench to loosen the filter core and unscrew it by hand. If the filter is still hot, remember to wear gloves. Don't worry, the filter core is screwed tightly, and the filter core will be damaged in the process of dismantling. As long as it doesn't damage the interface, the screws and the components around the filter are ok. After all, the removed filter cartridge is no longer in use.

Q:How to calculate the selection of each valve body in the pneumatic system? Determine the type of valve, work pressure, flow, and then determine the path, and then you can determine the specific model, so that right?

In fact, the valve itself is not difficult to choose.The fluid control system actuator generally not clear, need to choose according to the gas flow and pressure control fluid control components, but the control flow of fluid control required in general than the actuator need many small flow.
