Application scenarios and actual cases of high-pressure Irrigation hoses

The application scenarios of high-pressure irrigation hoses have expanded from traditional farmland irrigation to multiple fields. Its flexible adaptability makes it an important equipment for agriculture, gardening, industry and other industries. The following will introduce the main application scenarios by category and demonstrate its application effects with actual cases.

1. Agricultural irrigation: core application areas

Agriculture is the largest application area of high-pressure irrigation hoses, covering a variety of scenarios such as field crops, cash crops, and greenhouse planting. Its core value lies in improving irrigation efficiency and saving water resources.

(1) Field crop irrigation

In large-scale field planting of wheat, corn, rice, etc., high-pressure irrigation hoses are usually used in conjunction with reel sprinklers and center pivot sprinklers to achieve the integrated operation of "hose laying - high-pressure water spraying - automatic recycling". For example, in a 1,000-mu wheat planting base in Dezhou City, Shandong Province, a combination of "1.6MPa rubber high-pressure water hose + reel-type sprinkler" was used. Compared with traditional flood irrigation, it saved 60% of water per mu, shortened the irrigation cycle from 7 days to 2 days, and increased the yield per mu by 15%. (2) Irrigation of economic crops In the planting of economic crops such as fruit trees, vegetables, and flowers, high-pressure irrigation hoses need to meet the needs of precise irrigation. They are usually connected with drip irrigation belts and micro-spraying belts to achieve the conversion of "high-pressure transmission - low-pressure drip irrigation". Taking the 200-mu citrus orchard in Kunming City, Yunnan Province as an example, a "1.2MPa composite high-pressure water hose + drip irrigation system" was used. The high-pressure water flow was transported to the field drip irrigation main pipe through the water hose, and then accurately dripped into the roots of citrus through the drip irrigation belt. It not only saved 70% of water, but also reduced the loss of chemical fertilizers. The sweetness of citrus increased by 2-3 degrees, and the average income per mu increased by 3,000 yuan. (3) Greenhouse irrigation

The space in greenhouses is limited and the environment is closed, which places high demands on the portability and corrosion resistance of water hoses. Usually, PVC or PE high-pressure water hoses with a diameter of 25-50mm are selected and used with mobile sprinkler guns to facilitate flexible adjustment of irrigation positions. For example, a greenhouse vegetable base in Langfang City, Hebei Province, uses "1.0MPa PVC high-pressure water hose + handheld sprinkler gun" to shorten the irrigation time of a single greenhouse from 4 hours of traditional manual irrigation to 1 hour, and the water flow is uniform, and the incidence of vegetable diseases and insect pests is reduced by 20%.

2. Garden and lawn maintenance: refined demand scenarios

In urban gardens, parks, green spaces, golf courses and other scenarios, high-pressure irrigation hoses need to meet the requirements of refined maintenance while taking into account both aesthetics and durability.

(1) Urban garden maintenance

The trees, shrubs and flowers in urban gardens are scattered, and lightweight and easy-to-move high-pressure water hoses are required. For example, a municipal garden company in Beijing uses a "1.2MPa composite high-pressure water hose + small sprinkler" to irrigate the green belts on both sides of the city roads. The water hose is light and easy to fold, and can be easily carried to narrow areas, increasing irrigation efficiency by 50%. In addition, the color of the water hose is coordinated with the green belt, which does not affect the beauty of the city.

(2) Golf course maintenance

Golf courses have extremely high requirements for the uniformity and pressure stability of lawn irrigation, and usually use large-diameter, high-pressure rubber high-pressure water hoses. For example, a golf course in Shenzhen, Guangdong Province, uses a "2.0MPa rubber high-pressure water hose + high-pressure atomizing sprinkler system". The water hose can stably deliver high-pressure water flow, making the coverage of the atomizing sprinkler uniform, the lawn grows uniformly, and the maintenance cost is reduced by 30%.

3. Industrial and mining drainage: high-intensity use scenarios

In industrial production, mining and other scenarios, high-pressure irrigation hoses need to withstand high-intensity and high-corrosion use environments. They are mainly used for drainage and transporting industrial wastewater. (1) Industrial drainage

In factory workshops and industrial parks, High-pressure hoses can be used to discharge industrial wastewater or cooling water. For example, a machinery factory in Suzhou City, Jiangsu Province, uses "1.6MPa rubber high-pressure hose + drainage pump" to discharge cooling wastewater in the workshop. The hose is oil-resistant and corrosion-resistant, with a service life of more than 5 years and no need for frequent replacement.

(2) Mine drainage

A large amount of mine water is generated during mining, and it is necessary to use a high-pressure and wear-resistant hose for transportation. For example, a coal mine in Datong City, Shanxi Province, uses "2.5MPa steel wire reinforced rubber high-pressure hose + large drainage pump". The hose can withstand the high-pressure transportation requirements of mine water and has excellent wear resistance. It has a service life of 6 years in complex mining environments, reducing mine drainage costs.

4. Emergency and temporary water supply: flexible adaptation scenarios

In emergency scenarios such as flood disasters, droughts and water shortages, high-pressure irrigation hoses can be used as temporary water supply pipelines to achieve rapid water delivery. For example, when Henan Province suffered a drought in 2023, the local government mobilized a large number of "1.6MPa composite high-pressure water hoses" to connect rivers and dry farmland, build temporary water pipelines, and complete emergency irrigation of 20,000 mu of farmland in just 3 days, alleviating the drought.

V. Installation, maintenance and common problem solving of high-pressure irrigation hoses

Proper installation and maintenance are the key to extending the service life of high-pressure irrigation hoses and ensuring their safe use. The following will introduce in detail the installation steps, daily maintenance methods and solutions to common problems of high-pressure irrigation hoses.

1. Correct installation steps: ensuring safety and efficiency

(1) Preparation before installation

Check the appearance of the hose: confirm that the hose is not damaged, cracked, or aged, and the interface is not deformed or leaking;

Match the interface specifications: ensure that the hose interface is consistent with the interface specifications of the water pump and sprinkler equipment to avoid leakage due to interface mismatch;

Clear the paving path: remove sharp stones, branches and other obstacles on the paving path to avoid scratching the hose. (2) Installation process

Connect the water source interface: Connect the interface at one end of the hose to the water outlet of the water pump, and ensure that the connection is firm (the quick connector needs to be clamped, and the threaded connector needs to be tightened);

2. Lay the hose: Lay the hose according to the irrigation needs, avoid excessive bending or twisting (the bending radius should be ≥ 5 times the hose diameter), and keep the hose flat and without wrinkles;

3. Connect the terminal equipment: Connect the other end of the hose to the sprinkler, drip irrigation system or sprinkler gun, and also ensure that the connection is firm;

4. Water test inspection: Turn on the water pump and slowly increase the pressure to the working pressure. Check whether the hose has leakage, bulging, and whether the interface is well sealed;

5. Fix the hose: In areas with large slopes, use soil blocks or sandbags to fix the hose to prevent the hose from moving under the action of high-pressure water flow. (3) Installation precautions

Avoid direct contact of the hose with high-temperature objects (such as the engine exhaust pipe) to prevent aging and cracking;

Do not create negative pressure in the hose (such as when the water pump suddenly stops) to prevent the hose from being sucked flat and damaged;

When connecting multiple hoses, ensure that the working pressure of each hose is consistent to avoid the cracking of weak hoses due to uneven pressure.

2. Daily maintenance methods: Extending service life

(1) Cleaning after use

After irrigation, drain the residual water in the hose to avoid ice cracking in winter or bacterial growth in summer;

If fertilizer or pesticide solution has been transported, rinse the inner wall of the hose with clean water 2-3 times to remove residual corrosive substances;

Wipe the dirt and oil on the surface of the hose with a soft cloth to avoid scratching the surface with sharp tools. (2) Storage method

Storage environment: Choose a cool, dry, and ventilated warehouse to avoid direct sunlight and humid environment;

Folding method: Use "8" folding or reel storage to avoid excessive squeezing or folding (folding radius ≥ 10cm);

Avoid heavy pressure: Do not stack heavy objects on top of the hose during storage to prevent structural deformation;

Classified storage: Hoses of different specifications and materials should be stored separately to facilitate quick retrieval when next used.

(3) Regular inspection and repair

Inspect the appearance of the hose once a month. If minor damage is found, it can be repaired with special repair glue or patches;

Inspect the sealing of the interface once a quarter. If the interface is aged or deformed, it needs to be replaced in time;

Perform a water pressure test once a year to test the high-pressure resistance of the hose. If the pressure drops by more than 20%, a new hose needs to be replaced.

VI. Current status and future trends of the high-pressure irrigation hose industry
