Welded Plate Heat Exchanger belongs to Recuperative Heat Exchanger, and is fully welded between every two plates to form channels through which the fluids with different temperature can flow and exchange heat. The high temperature fluid transfers heat to the low temperature fluid through the plates, thereby realize heat exchanging. The flow velocity of each fluid can be controlled by plates distance, so as to meet the working condition perfectly. In addition, there is also the semi-welded type plate heat exchange.
Welded Plate Heat Exchanger is mainly for vapor condensing and liquid to liquid heat exchanging, to meet with various requirements from industries like power sector, petrochemical, petroleum coking, pharmacy, metallurgy, refrigeration, paper processing etc. Optimal arrangement of various channels also make sure of high heat transfer efficiency and minimal pressure loss. Besides, its frame is detachable, and therefore it is convenient to have either mechanical cleaning or chemical cleaning as per actual situations.

Many car owners are not accustomed to driving an automatic car after they finish the manual transmission. They have a lot of experience in driving manual vehicles, such as “neutral gliding†but this will not be used in automatic vehicles. "Vital gliding" destroys the car? The truth turned out to be this way.
When the automatic car driving is very fast, you only need to catch the throttle to reduce the speed, then the problem has arisen. When the engine recovers oil, the speed of the engine decreases, and the speed of the transmission suddenly decreases. What will happen to the engine? I believe that the majority of owners have experience, that is, the speed began to decline, this deceleration is driven by the engine to drive the transmission, then this deceleration will not damage the transmission it? In fact, this is only an extended issue. The question to be asked this time is: "What is the effect of the neutral coasting on the speed change? Will it damage the car's gearbox? What happens to the gearbox when we are engaged in neutral (N)? In fact, it is very simple that the transmission components in the gearbox are idling, that is, the sun gear, planet carrier and ring gear are not fixed by the relevant components. When we engage the N block from the D block, the power of the engine still changes through the hydraulic torque. The transmission to the transmission, that is to say, the transmission's oil pump has been working.Speaking of this there will be many people doubts, before always listening to people saying that when the transmission is in the neutral gear, the transmission is easily damaged because the oil supply and heat dissipation problems are not solved. The fact that the “neutral glide†destroys the car actually turns out to be the fact that the input shaft runs with the sun gear when it is in neutral and drives the planetary gears to rotate. The planetary gears in turn rotate the ring gear, but it is in the neutral gear ring and the planetary carrier. Neither is fixed, the input power is not transmitted to the output shaft, so the governor will not send a rotational speed signal to the transmission oil pump (the oil will not be interrupted), and After the pump is in the torque converter, ie the oil pump is working, at least the pressure inside the gearbox will always be maintained at a basic pressure.The problem is that this basic pressure can not meet the lubrication and heat dissipation of the gearbox. Since the transmission oil pump is able to pump oil, the fact is that the gearbox is not damaged due to lack of lubrication as many people say. (The specific use is based on the manual of the vehicle, and there are differences in different brands of automatic transmissions.)
Regardless of whether your car is an automatic or a manual transmission, the Master recommends that you do not hang a neutral gear when you go downhill, not because the damage does not damage the transmission, but is a matter of personal safety. When the neutral gear is downhill, it loses the effect of braking the engine (some vehicles have a traction control system). The speed will be faster and faster. If unexpected situations occur at this time, the consequences will be disastrous.
