What kind of problems are caused by the abnormal sound of the wiper? How can we solve it? Let us help you.
1. If it is when it is up, then it means that the wiper frame is twisted upwards, so that the wiper is stopped in the middle position (the steering wheel pulls the wiper control handle after turning off the car), and then gently pull it up with a cloth or something soft Wrap the steel frame and use a spanner or pliers to hold the wrapped part down and twist it a few times. After the reset, scrape and try. Is the abnormal sound small? If yes, repeat it until the noise disappears. If it begins to go down, it means that the wrench is over-twisted and it needs to be twisted in the opposite direction. Until abnormal noise is eliminated!
2. If it is going down, it means that the wiper frame is twisted downwards. After the wiper is parked in the middle, it is set up. Use a cloth or soft thing to wrap the steel frame and use a wrench or pliers to hold the package. Twist the wrench a few times and try to scrape after the reset. Is the abnormal noise small? If yes, repeat it until the noise disappears. If it becomes the upper line and it starts to ring, it means that the plate has been twisted too much and it needs to be twisted in the opposite direction. Until abnormal noise is eliminated!
3. Careful and patient operation is required. You can't use it too hard, so as not to get into worse troubles, it's best not to be afraid of trouble. Take out the boneless wiper and operate it. If you do not have any experience in this area, or go to the 4S shop, let them tune in accordance with this principle will generally solve the problem.
4 If a single wiper blade has abnormal sounds when it is up and down, it is time to change the wipers!
U tube heat exchanger is suitable for the large temperature difference between tube side and shell side. The shell side media is easy to scale and needs cleaning, while the tube side media is clean and not easy to scale. It is also suitable for high temperature, high pressure, fluid corrosive working conditions.
Each heat exchange tube is bent into U-shape, the two ends are fixed in the upper and lower areas of the same Tube Sheet, and divided into two chambers of inlet and outlet with the partition in the tube box. This kind of heat exchanger completely eliminates the thermal stress, the structure is simpler than the floating type, but the tube side is not easy to clean.
The number of tubes is small, the utilization of the tube sheet is not frequent, and the shell side fluid is easy to short circuiting, which is unfavorable to heat transfer. If there is a leak or damage in the tube, the external U-tube can be replaced, while the broken inner tube can not be replaced, only plugged, and one broken U-tube means two broken, so the U-tube easily scrapped.
