Buying and maintaining a car is easy. Take the example of a simple car wash. Many car owners like to go to car washes, which is not only expensive and time-consuming, but sometimes they have to wait in line. Many car owners have complained.
Actually, the best way is to clean and maintain your car more carefully to save time and avoid trouble. Today we specially selected a Bosch car washing machine to see the real effect of this top brand car washing machine.
Let's take a look at the appearance first. The compact and portable body can be carried with one hand and the design is very user-friendly. Small items such as water spray guns, buckets, foam bombs, nozzles, etc. Designed with a storage location, it can be easily stored in the car wash. You can washyour car with a washing machine and a garden hose.
The first step is to assemble it. The assembly is actually very simple. Under normal circumstances, owners can easily assemble it once installed. But you must read the instructions carefully the first time, otherwise it is easy to make your own mistakes (personal experience).
First install the water inlet pipe. There are two ways for water to enter this car washing machine. One method is to directly connect the faucet, hang a small rope on the faucet, tighten the screws on the water pipe and that's it. If you use a bucket to absorb water, you must install a filter. If you immerse it in a bucket, the pump can suck up water on its own.
The high pressure water outlet pipe is made of black explosion-proof PVC material, much more delicate than the water inlet pipe. Aftereverything, you have to withstand high pressure. One end is connected to the mouth and the other end is connected to the body (remember to tighten the screws).
On the left side of the fuselage is the location for the power cord. Plug in the power cord (a long plug is recommended). The length of the power cord is approximately 5 meters. Coupled with the length of the external hook, it will be much more comfortable to wash the car without feeling like you are strapped in the back. There is a circular button on the fuselage, which turns off when it points to the number 0. When it points to the number 1, it lights up.
Next, let's look at actual usage. There are high-pressure nozzles (high-pressure decontamination and flushing) and variable nozzles (adjustable spray patterns). A foam bottle can be hung under the nozzle, into which the corresponding cleaning agent can be added to spraythe body of the car.
The distance of the spray gun is approximately 6 m. Stubborn stains can be easily removed with the high pressure mode, and the fan mode can be used in easy-to-clean areas with greater efficiency.
High pressure mode can clean dirt from tires and wheels.
It can also easily remove stains or bird droppings on body paint and glass. After spraying the dishwashing liquid, wipe it with a cloth, then rinse it with a water gun. The cleaning effect is good. If you want to protect the paint surface, you can also pour the wax mixed with water into the foam tank under the nozzle after cleaning to easily spray the wax with water.
Let's take a look at the effect of domestic use (when my friend went abroad, the courtyard of the villa was dirty for a few days, youWe'll know after trying it). First, rinse the soil in your yard well. The fan mode is more effective. With a few soft brushes, the floor will be clean as new, while the high pressure mode is better for some stubborn stains on the seams.
The grape trellis, the lawn in the yard, watering friends and cleaning floors, railings, furniture, etc.
Let's evaluate the cost of self-service car washes:
Wash the car, throw the whole thing away, replace it with dish soap and wipe it down. Washing time is usually around ten minutes. The rice tested this time hardly changed much. We calculated the approximate cost based on electricity production and water production:
Electricity costs: the rated power is 1300W and the power consumption is approximately 0.22 kWh in 10 minutes. Electricity fees are calculated at 0.5 yuan/kWh for networksurban idents, i.e. 0.22*0.5=0.11 yuan.
Water charges: the water flow is 5.5L/min, the water consumption in 10 minutes is about 55L, one ton is 100L and the price of a ton of water is about 3 yuan. The water fee is 55/1000*3=0.165 yuan.
The total water and electricity bill is 0.275 yuan. Even if there are some mistakes, the cost of washing the car will not exceed one yuan, and it will take about 15-30 minutes.
Using experience:
The cleaning effect is good. High pressure mode can easily remove moss on walls, stains on floors, dirt on tires, etc. Spray dish soap first, then rinse. Once wiped with a cloth, the car is perfectly clean.
In fact, washing your car is also a pleasure in life. Many car enthusiasts wash their own cars not only for exercise, but also to save money.I wonder if you want to wash your car by hand after reading this article?

Check the amount of heat needed to convert a ton of water into steam, based on from heating water to more than ten degrees to saturated steam (198 degrees) Calculate the amount of heat generated by the combustion of one ton of natural gas, 8.4 × 10^7 J/cubic meter. Natural gas is generally measured in cubic meters. Check the efficiency of a steam boiler, usually 65% to 70%. 1 ton/hour boiler = 600,000 kcal/hour = 600,000 kcal heat, 600,000 kcal divided by 90% boiler thermal efficiency (general efficiency of oil and gas furnaces) = 666,666 kcal (power calorific value) The calorific value of natural gas is generally 8,500 Kcal/per cubic meter: 666,666 divided by 8,500 = 78 cubic meters. The above shows that a 1 T gas boiler requiresite 78 cubic meters per hour, which are then multiplied by the unit price of natural gas per cubic meter. is 4.28 yuan/cubic meter x 78 cubic meters = 333 yuan. It is calculated like this: According to the steam thermal parameters table, the inlet and outlet pressure and temperature are used to find out the enthalpy values of the operating point h in and h out, the mass flow rate of steam X (h in - h out) X turbine efficiency = 4.186X860 Mass flow rate is what you call steam consumption. The electricity consumption of oil and gas boilers is not very high, around 2 kW for those powered by coal and that for electric heating is more than 700 kW. For the same ton of steam, the power generation capacity is also different due to. different pressures and superheat temperatures. A ton of steam can generate about 340 degrees of electricity. Around 720KW. THEoperating cost of electric boilers is relatively high. It is recommended to use a gas steam boiler. Running costs are much lower than electric boilers. And it’s also environmentally friendly. This depends on the steam consumption rate of your unit. For example, if the steam consumption rate is 4 kg/kWh, then the electricity production is 84,166 degrees and the steam consumption is 21,042 kg, which is approximately 21 tons of main steam. How many kilowatt hours of electricity does a boiler need to produce a ton of steam? of power plantThe boiler is fully inspected and equipped with instruments. The Power Equipment Department tested it and found that it uses 10 tons/hour of steam at 50-57 degrees/ton of steam.
