After a heavy rain, the weather is often hotter and the sun is more pungent. After more rain and intense sunlight will accelerate the aging of car paint and parts, regular routine maintenance should be done, but this is just a Expedient measures, for the time being, we must have the opportunity to make real car body repairs or paint repairs to the car carefully, and eliminate these failures in the bud. The following Xiao Bian will introduce you to several kinds of summer car maintenance methods.
Externally Heated Desiccant Compressed Air Dryers
For decades, compressed air users have relied on YUKA HL-WR series heated desiccant air dryer to deliver technology that reduces the cost of operation and improves the reliability of air driven processes.
The HL-WR Series is engineered to deliver ISO 8573.1. Air Quality and reduce purge air consumption.
The micro heated regeneration adsorption dryer is a kind of humidification purification device that uses micro heat regeneration method to adsorb and dry compressed air according to the principle of pressure swing adsorption.
Feature & benefit
1. Micro-thermal regeneration adsorption dryer (hereinafter referred to as micro-thermal suction dryer), which has the advantages of both heating regeneration and non-thermal regeneration. The regeneration gas is micro-heated to reduce the regeneration air consumption and the regeneration is more thorough, Extend the tower switching cycle.
Under normal operating conditions, the dew point (under pressure) of the air can be reduced to below -40℃, and the lowest can reach -70℃. It can provide oil-free and water-free high-quality compressed air for a few applications that have high requirements for air quality.
It is especially suitable for use in cold areas in the north and other places where the ambient temperature is below 0°C.
2. The micro heat absorption dryer adopts a double tower structure, one tower absorbs moisture in the air under a certain pressure, and the other tower uses a small portion of dry air slightly higher than atmospheric pressure to regenerate the desiccant in the adsorption tower after a certain period of time , The two towers are switched to ensure continuous supply of dry compressed air.
3. On the basis of having all the advantages of the non-heat regenerative adsorption dryer, it adopts high-quality stainless steel finned U-shaped heating tube, which has uniform heating and high heat transfer coefficient, which can ensure long-term trouble-free operation.
4. Unique computer control system, visually display the running status of the dryer, and has multiple alarms, protection functions and DCS remote control interface to ensure trouble-free use.
5. The actuator adopts pneumatic angle seat valve and pneumatic butterfly valve. The pneumatic control system adopts deep dry air source and then filtered to ensure reliable action and avoid valve leakage.
6. The height and diameter of the adsorption tower are accurately calculated and experimental results, and the important parameters such as flow velocity and heat and mass transfer are indeed mastered, so as to avoid excessive wear of the adsorbent and tunnel effect.
7. Professional program control design, small air pulse and air pressure fluctuation, effectively reduce the outlet air dust and the regeneration air noise.
8. Convenient and practical cycle time mode and energy-saving economic mode. Regenerative air volume and time program can be adjusted to adapt to various actual use conditions and outlet dew point requirements. The support base has a stable and beautiful appearance, and is easy to install, use and maintain.

Timely cleaning
In the event of heavy rain, the car should be cleaned in time after returning. Otherwise, sludge may accumulate in the voids on the underside of the vehicle. This is where the moisture can be concealed, and where rust is most likely to occur.
Paint protection
The acidity of rainwater has a strong corrosive effect on the car's paint finish, and it will cause damage to the car's paint over time. Therefore, in the rainy season, it is best to give the car a paint finish. The simplest is waxing, and longer and more effective is the sealing capacity. No matter what kind of method, give the car an invisible protection coat to prevent the fading and aging of the paint, so that the bright car capacity often accompanied.
Chassis care
The chassis is the closest part to the ground and is particularly affected by the road conditions. Generally, this part is the most likely to be rusted and stained, and the wheel shell may even be loosely perforated. Therefore, we must pay attention to the car chassis clean anti-rust treatment, do a chassis rust treatment, anti-rust effect can be maintained for 3 months. After doing anti-rust care, be careful not to use alkaline cleaning solution to rinse the body and chassis. This will affect the anti-rust effect and shorten the anti-rust time.
Ignition start
In rainy days, owners often run into problems with engines that are not easy to start, and sometimes even if they are barely started up, they are weak. The greatest possible cause of this problem is the leakage due to moisture from the ignition system. In addition, it may be as soon as the rainy weather becomes cooler, and the hot air enclosed in the sub-distributor may condense into water droplets, causing a small flood inside the sub-distributor, thus losing the normal ignition function.
Once it is discovered that the ignition system is poor due to the wetness of the ignition system and engine performance is degraded, it is best to dry the inside and outside of the distribution board and the wires with a dry paper towel or dry cloth, and then spray the desiccant with a special desiccant spray can. At the distributor cover, battery connector, spark plug, high-voltage line and ignition coil, wait for a while to start the engine.
Brake water removal
The vast majority of car brake systems are dual-line vacuum assisted hydraulic brakes. It is worth noting that the brake fluid that transmits the braking force has extremely strong water absorption. If water enters the brake fluid, the heat generated by the friction will vaporize the water during braking. The gas is compressible and it is compressed in the brake fluid, causing brake failure or even failure.
When there is a lot of rain, the humidity of the air will increase. If the brake fluid has a small amount of moisture before the rainy season comes, it will be very dangerous. In some vehicles where brake fluid absorbs water, droplets of water can be seen on the lid of the brake fluid cup. Therefore, the brake fluid must be checked during maintenance to ensure the safety of the occupants.
