Characteristics of Rams of GerPol Design
Категория: Сельское хозяйство | Новость от: Admin | 22-11-2005

We have a pipe the one end of which is connected to the pond filled with water and the tube is added to the other end (vertically to the upward). Its diameter is less than the pipe.
If the outlet section of the pipe is closed the water in the pipe is lifted to the level of water elevation in the pond as in communicating vessels. At the same time if this hole is open, then a few minutes later it is instantly closed then the severe regime change of water flowing a taken place and the so-called water hammer occurs which is followed by alternate increscent and reduction of pressure. Due to the increscent of the pressure the water is lifted in the pipe higher of water elevation in the pond. Reporting the process some portion of water passing through the pipe is lifted to the highest marker in comparison with water level in the pond.
Hydraulic ram is designed according to this principle. It consists of the following main details.One or several impact valves are located on the body, which periodically open or close the outlet section of the feeding pipe, thereby causing water hammer. From the ram body the water is injected into the air valve under the pressure through the injecting pipe – to top. The injection valve is used for prevention of reverse flow (motion) of water from the injecting pip-line during the reduction of pressure in the feeding pipe-line. The air valve which is filled with air during the ram operation is used as a shock-absorber that is water hammer is softened and the capacity of the shock spreading (propagation) is prevented in injecting pipe-line, the injection flow rate becomes uniform. There are the following requested data for the choice of the type of ram: the consumption of water source (Q), the expected drop height (H), that is, the feeding pressure, requested injection height (h0 and requested injecting consumption (q). The ram of the GerPol type as water-lifted machine can also be used for the irrigation of small lands. Characteristics of the Rams of GerPol type is the following (approximate)

  GerPol - 100 GerPol - 150 GerPol- 250
Feeding pressure (H) in meters 1….50 1….30 1…10
Injecting pressure (h) in meters 2,5 ….100 2,5 …100 2,5…20
Spillway capacity Q in l/sec Till > 10 Till 25 Till 60
Productivity when h/H+2.5 l/sec Till 3 Till 7 Till 18
