How to choose a suitable high-pressure cleaning machine?

General high-pressure cleaning machines can be divided into household and professional use. If you use the cleaning machine for less than 50 hours a year, you only need to buy a home cleaning machine. Relatively cheap price, light weight, simple material and heat resistance. If the service time exceeds 100 hour, it is necessary to consider professional high-pressure cleaning machines, which are bulky, durable materials such as copper alloy pump heads and stainless steel valves, and the prices are definitely much more expensive. So how to choose depends on the needs of consumers.

2. According to the demand for hot water and cold water:

According to different occasions, high-pressure cleaning machines can also be divided into hot water and cold water. Generally, most of the water in the market is cold water, which can be used by injecting normal temperature water into the faucet; However, some business premises need to be washed with hot water. At this time, it is necessary to buy a hot water high-pressure cleaning machine. If hot water is injected with cold water rashly, the internal parts, including the water pump, will be damaged quickly, and the loss will outweigh the gain.

A heating device is added to the hot water cleaning machine, and the water is usually heated by the combustion cylinder. Using hot water cleaning can quickly wash away a lot of dirt and oil stains that are not easy to wash away in cold water, which greatly improves the cleaning efficiency. However, due to the high price and operating cost of hot water cleaning machines (because diesel oil is used), most users may choose ordinary cold water high-pressure cleaning machines; Of course, in order to improve the cleaning efficiency and effect, there are still many professional customers who will choose hot water cleaning machines.

3. Also choose a nozzle:

Different nozzles have different cleaning effects. For example, the circular water column nozzle can increase the cleaning efficiency, the fan-shaped nozzle can rotate the nozzle as a low-pressure spray (soapy water can be sprayed) and a high-pressure fan-shaped water column, and the low-pressure brush head can spray low-pressure water for gentle scrubbing. Some of these nozzles will be given away, and some must be purchased by themselves. When buying, you should choose according to your own needs.

Select enterprise

There are many brands of cleaning machines on the market, and the imported ones are more expensive than the domestic ones 1-2 times or even more, so the choice should be based on your actual needs and budget. Generally, imported equipment has new technology, which has certain advantages in durability and efficiency compared with domestic equipment, but the price is also much higher, and the maintenance cost is 2-3 times higher than that of domestic equipment. After choosing the brand to use, you should also pay attention to the choice of merchants.

Maintenance method

Daily maintenance-after each operation

1. Rinse the connected hoses and filters with detergent to remove any detergent residue, thus helping to prevent corrosion.

2. Turn off the water supply system connected to the high-pressure washer.

3. Pull the trigger on the servo spray gun lever to release all the pressure in the hose.

4. Remove the rubber hose and high-pressure hose from the high-pressure cleaning machine.

5. Cut off the connecting wire of the spark plug to ensure that the engine will not start (suitable for the engine type).

Electric type:

Turn the power switch to the "ON" and "OFF" positions for four to five times, each time 1-3 seconds, to remove water from the pump. This step will help protect the pump from damage.

Engine type:

Slowly pull the starting rope of the engine five times to remove the water from the pump. This step will help protect the pump from damage.

Regular maintenance-once every 2 months.

1. Regular removal of fuel deposits from the fuel tank will prolong the service life and performance of the engine. Fuel deposits can damage fuel pipes, fuel filters and carburetors.

2. When the high-pressure cleaning machine is not used, protect the high-pressure cleaning machine with the protective kit of the cage pump (9.558-998.0). The protection kit of the pump is specially designed to protect the high-pressure washer from corrosion, premature wear and freezing. Apply lubricant to the valve and sealing ring to prevent sticking.

Electric type:

1. Turn off the high-pressure washer.

2. Disconnect the high-pressure hose and servo spray gun rod from the pump.

3. Connect the valve to the pump protection box and open the valve.

4. Start the cleaning machine; Suck everything in the tank into the pump.

5. Turn off the cleaning machine; The high-pressure cleaning machine can be stored directly.

Engine type:

1. Turn off the high-pressure washer.

2. Disconnect the high-pressure hose and servo spray gun rod from the pump.

3. Connect the valve to the pump protection box and open the valve.

4. Ignition, pull the starting rope; Suck everything in the tank into the pump.

5. The high-pressure cleaning machine can be stored directly.

Matters needing attention

1 When operating the high-pressure washer: always wear appropriate goggles, gloves and face mask.

2. Always keep hands and feet away from the cleaning nozzle.

3. Be sure to check all electrical connectors.

4. Be sure to check all liquids.

5. Be sure to check the hose for cracks and leaks.

6. When the spray gun is not used, it is always necessary to set the trigger in a safe locking state.

7. Always work with the lowest possible pressure, but the pressure should be enough to finish the work.

8. Before disconnecting the hose, be sure to release the pressure in the cleaning machine.

9. Be sure to drain the water from the hose after each use.

10 Never aim the spray gun at yourself or others.

1 1. Do not start the equipment until all hose connectors are locked in place.

12 ... Do not start the equipment until the water supply is connected and proper water flows through the spray gun rod. Then connect the required cleaning nozzle to the spray gun rod.

Attention: Do not leave the high-pressure cleaning machine in an unsupervised state during operation. Every time the trigger is released, the pump will run in bypass mode. If a pump runs in bypass mode for a long time, the high temperature of circulating water in the pump will shorten the service life of the pump and even damage the pump. Therefore, it is necessary to avoid operating the equipment in bypass mode for a long time.

Market analysis of high-pressure cleaning equipment

The analysis of market survey results shows that high-pressure washing machines have broad market development potential in China, and high-pressure washing machines from developed countries have been widely used in China, with great market demand and an increasing trend. However, the market survey and analysis in the domestic market found that the domestic high-pressure washing machine market should still be in its infancy, and the use of high-pressure washing is still rare, and it is limited to large and medium-sized enterprises. However, with the rapid development of economy, especially the rapid development of automobile industry and the popularization of automobiles, people gradually improve their living environment and improve the quality of their living environment. The domestic high-pressure cleaning equipment market is also growing rapidly, and the market demand is also increasing rapidly.
