One of the important components when installing an autonomous water supply system is a water intake hose for a pumping station. The performance of the system depends on its strength, elasticity, strength. If the hose breaks down (breaks, deforms), the pressure in the pipeline drops, the liquid does not flow to the taps, the pumping equipment either runs idle or turns off.
Purpose of the hose for the pumping station
A reliable water supply hose is used for the following purposes:
- intake of liquid from the source and its transportation to the storage chamber of the unit;
- transfer of water further through the system;
- watering, irrigation of garden crops.
It is desirable that the intake hose has sufficient wall thickness. Otherwise, the material will tear quickly, especially when used in a garden with constant movement or when working with high pressure.
Varieties of hoses
All water supply hoses are classified according to length, section and materials. The last parameter is important. There are such types of hoses on the market:
- Rubber. Most flexible of all models. The main advantages are elasticity, favorable price. However, the rubber hose cannot withstand the high pressure, which is inevitable, especially when supplying water from a well. In addition, at low subzero temperatures, rubber dubs. As a result, such a flexible hose for the pumping station bursts faster.
- Silicone. They are also characterized by increased elasticity and softness. However, these same qualities work against the fact that the silicone sleeve is mounted at the entrance to the pumping station. Especially if the water rises vertically at a high altitude (well). Here, the hose may simply not withstand the weight of the water in it and additional equipment (check valve, filters). It is better to use silicone hoses only in summer for watering.
- PVC sleeves. Polyvinyl chloride is more rigid than rubber and silicone. It withstands mechanical stress, temperature and pressure drops.
In addition to materials, design features of the pumping station hose are distinguished. For each type of water supply hoses, two versions are possible:
- The usual. Does not imply anything in the thickness of the walls, except for the base material (silicone or rubber). These suction hoses are not reinforced. The service life of products with careful handling is 5-7 years. The maximum working pressure is 3 atm.
- Reinforced (reinforced). The production technology of products implies the introduction of a steel thread into the thickness of the base material. This technique allows you to extend the service life of the product up to 20 years, but reduces the indicators of its elasticity. Reinforced hoses withstand temperature drops and can operate at high pressures from 7 to 24 atm. Technical characteristics of reinforced sleeves: internal section from 8 to 30 cm; radial bend 11-41 cm; wall thickness from 2.6 to 4.5 mm.
When buying a high-pressure hose for a pumping station, you should take care of reliable, durable fittings and fittings for it. Otherwise, the sleeve may rip off during operation.
There is a variety of reinforced sleeves - corrugated. They are based on a durable metal spiral. At the same time, the lightweight corrugation can be used specifically for pumping equipment. Heavy and medium types of spirals are used in drainage systems, since they have greater rigidity.
Criterias of choice
When buying a hose for pumping equipment, it is advisable for the master to rely on the following criteria:
- Length of the product. It should be enough from the point of water intake to the unit. If the length of the sleeve is excessively long and at the same time there is a reinforcing fiber in the material, it will be quite difficult to twist the hose, but it is a pity to cut it into two pieces. Short sleeves are even trickier.
- Manufacturing material. For systems operating under high pressure, it is better to use reinforced PVC hoses. For watering, you can use rubber, silicone products.
- Rigidity. It is extremely important if the hose is intended for use in conditions of changing temperatures and pressures. The reinforced hose will not lose its shape from this, will not collapse or deform. The best solution is corrugated or reinforced hoses.
- Frost resistance of the material. It is especially important if the sleeve is purchased for operation in low temperatures (northern regions of Russia).
- Section. The hose diameter in inches must match exactly the size of the inlet.
When choosing products, it is better to take ready-made hoses with a check valve. Additionally, you need to buy fittings, coarse filters, seals. If there is a need to make a turn of the line at an angle of 35-55 degrees, you can buy a short metal hose. This will eliminate water hammer.
Features of installation and operation
To independently connect the sleeve to the pumping station, you should prepare strong clamps and a roll of knitting wire. First, one end of the hose should be immersed in soapy or hot water. This manipulation will make it easier to slide the hose onto the inlet nozzle.
At the end of the sleeve, put on two clamps and carefully push them along the thread a little further from the edge by 5-7 cm.
The prepared hose is pulled over the nozzle, gently loosening it from side to side or scrolling clockwise. The put on sleeve is fixed with clamps.
For proper operation of the hose, it is better to adhere to the following recommendations:
- It is advisable to lay the hose with a slope of 5 degrees from the point of water intake to the unit. Thanks to this approach, freezing in the pipeline in winter is excluded.
- It is advisable to avoid kinks in the water supply line.
- If the hose will not be used in winter, it is either removed along with the station, or a water seal is made through a slight sagging of the sleeve.
A correctly selected and installed water inlet hose serves without failures, deformations, breaks.
