Disadvantages of steam car washers:

1. The problem of unstable firepower of gas cylinders. Gas tanks are affected by temperature. The pressure of the cylinders in winter and summer is different, resulting in different firepower. Even in winter, the firepower of the same tank on the ground and in the basement is different; the pressure of a full gas cylinder and a tank that is almost empty are also different. Firepower is also different.

So there will be this problem: in winter, some gas machines will produce hot water but not steam if they are used for a long time; or the gas tank still has one or two kilograms, the firepower cannot keep up, and the steam cannot be produced properly. It would be a pity to throw it away; of course, before this issue was thoroughly studied, we would simply open the gas valve or throw away the remaining gas. This will cause a huge waste!

2. Electronic control problems. The operating conditions of gas steam engines are relatively harsh, with both water and steam, and some are relatively humid in the basement. They have to work continuously for more than 10 hours every day when the car is being washed, and workers do not pay much attention to their operations. This machine is different from a TV that just needs to be turned on. Workers have to fiddle with it every day, and the use environment is not good, so it will inevitably malfunction.

The original electronically controlled circuit boards are very well designed. The problem is that once a certain capacitor burns out under such working conditions, it cannot be repaired by non-professionals or by returning to the factory. of. In order to improve stability and provide after-sales convenience, all upgraded machines adopt mechanical electronic controls, which means stringing buttons, signal lights, and relays together, and any electrician can do the repairs.

3. The problem of heat exchanger oxidation. This heat exchanger was first made of aluminum castings (some are still in use today). The melting point of aluminum is too low. Later, it was changed to expanded copper tubes, and it was found that copper is easily oxidized. The heat exchanger is burned on a fire and the temperature is extremely high. What should I do about this problem? The upgraded heat exchanger is made of stainless steel, and there are no solder joints in the heating part. It should be very reliable!

Extended information:

The instantaneous steam car washing machine uses "instantaneous vaporization" technology: under the action of a small water pump, a small amount of water flows through the heating tube, absorbing heat during the flow process An environmentally friendly car washing method that turns gas into steam and separates car surfaces and stains. This steam production technology has the following advantages:

1. There is no high-pressure container (boiler), which is relatively safe.

2. Instant heating technology can heat as much as needed, with high thermal efficiency, energy saving and low usage cost.

3. It starts up very quickly even when the machine is cold. You can use it whenever you want. It is flexible and convenient.

4. Pipe heating, not easy to scale.

5. The pressure under continuous steam release is high and stable.
