How to choose a pressure washer?
2022-05-05
General pressure cleaners can be divided into two types: household and professional. If you use the washing machine less than 50 hours a year, you only need to buy a household washing machine. The price is relatively cheap, the weight is lighter, the material is simple and not heat-resistant.
If you use it for more than 100 hours, you should consider a professional high-pressure cleaner, which is larger in size and made of durable materials such as copper alloy pump heads and stainless steel valves. Of course, the price is also much more expensive. So how to choose should depend on the needs of consumers.
2. Depending on the need for hot and cold water:
Depending on the requirements of the occasion, high-pressure cleaners can also be divided into hot water and cold water types. In general, most of the cold water type on the market can be used by injecting normal temperature water into the faucet. However, some business places need to be washed with hot water. At this time, a hot water type high-pressure cleaning machine must be specially purchased. If the hot water is injected, the internal parts including the water pump will be damaged very quickly, which is not worth the loss.
A heating device is added to the hot water washer, which generally uses a combustion cylinder to heat the water. Using hot water to wash can quickly wash away a lot of dirt and oil stains that are not easy to wash with cold water, which greatly improves the cleaning efficiency.
However, due to the high price and high operating cost of hot water cleaning machines (because diesel is used), most users may choose ordinary cold water pressure cleaning machines; of course, in order to improve cleaning efficiency and effect, many professional customers will choose Hot water washer.
3. Also choose the nozzle:
The cleaning effect caused by different nozzles is also different. For example, the circular water column nozzle can increase the cleaning efficiency, the fan-type nozzle can rotate the nozzle as a low-pressure spray (soapy water can be sprayed) and the high-pressure fan-type water column, and the low-pressure brush head can spray low-pressure water for gentle brushing, etc. Some of these nozzles will come with a bonus, and some must be purchased by yourself. When purchasing, you must refer to your needs and choose carefully.
4. Select a merchant
There are many brands of cleaning machines on the market. Imported ones are 1-2 times more expensive than domestic ones, or even more. The choice should be based on your actual needs and budget. Usually imported equipment has new technology, and its durability and efficiency have certain advantages over domestic equipment, but its price is also much higher, and the maintenance cost is also 2-3 times higher than that of domestic equipment. After choosing the brand to use, you should also pay attention to choosing the merchant.
There is almost no direct sales of domestic high-pressure cleaning manufacturers, especially imported products, which are all in the form of dealer cooperation. Generally, there is only one legal official dealer in a region. When choosing, you must choose a qualified dealer to ensure after-sales service. , Because cleaning equipment is like a car, it is three-part maintenance and seven-part maintenance. If you want to buy it through informal channels, it will cause a lot of trouble in future maintenance and maintenance. It is likely that the loss of a small part will cause tens of thousands of yuan. use. If conditions permit, it is recommended to sign a maintenance agreement with the merchant.
