OPERATIONAL RELIABILIT Y OF PUMPING STATIONS, DESIGN OF PUMPING STATIONS ACCORDING TO THE PURPOSE OF USE PLAN 1. Pump units. The pump station includes the following facilities and devices include: water intake facility, water transfer facility, avan camera, water intake facility, suction pipes, pump station building, pressure pipes, water outlet, pressure tank, drainage channel. The water intake facility is constructed to guarantee the water consumption to the pump. This structure is provided by zatvors.In addition, devices that do not transfer discharge and fish to pumps can also be envisaged in the water intake facility. The water transmission structure can be in the form of an open channel or a closed pipe. This structure will be built as part of stations operating according to the derivation scheme. The dimensions of the water transfer facility are assigned on the basis of hydraulic calculations. Avankamer water transmission system with water intake system is a connecting part. The water intake facility is usually from the water transfer facility will be wider and deeper. The pump station building consists of the main working areas and service rooms is organized. It includes pumps, motors, power transmission devices, control panel, lifting cranes and the like are located. Cross section of the pump station building: 1 – suction pipe, 2 - pumps, 3 - lock, 4 - reverse valve, 5 - pressure pipe, 6 – load lifting crane Pressure (driving) pipes pumps with water discharge facilityconnects. Also with locks and reverse valves in pressure pipesmust be provided. The main function of the water outlet is the pressure pipe coming outto ensure that a minimum napor loss is achieved when transmitting the stream to the upper byefwell the back of the water in the pressure. Basin when the pump unit stops workingthis is to prevent (pumps to the side) from returning sharply. Pressure basin with drainage system connects. The location schemes of the pumping station are based on the geological, hydrogeological, hydrological and topographic conditions, technical and economic solutions and may vary depending on other factors Derivative scheme pumping station the building will be built as close as possible to the irrigation field. (pressure to reduce the length of the pipes) Industrial and domestic wastewater, atmospheric water and precipitation (turbid) it could not flow to the treatment stations due to the local relief In some cases, sewage pumping stations will be built.. Production enterprises of sewage pumping stations (food except for industry), to free areas near warehouses, or it is advisable to build in greened arrays. Sanitariya shartlari bo‘yicha nasos stansiyalarni turar joy va jamoatchilik binolaridan 20–30 m uzoq masofada bo‘lgan alohida binolarda joylashtirish zarur. Agar bo‘sh hudud bo‘lmasa, oradagi masofa Davlat sanitariya qo‘mitasi bilan kelishilgan holda kamaytiriladi. Nasos stansiya hududi perimetri bo‘yicha eni 10 m kam bo‘lmagan himoyako‘kalamlashtirish zonasini qurish zarur. Atmosfera suvlarini xaydovchi nasos stansiyalarini rostlovchi hajm sifatida ishlatish mumkin bo‘lgan suv xavzalari yonida qurish mumkin. Kanalizatsiya nasos stansiyalari qurilish joylarini mahalliy sanitar-nazorat organlari va suv xo‘jaligi Vazirligi bilan kelishilgan holda tanlanadi. Kanalizatsiya nasos stansiyalarining tasnifi, tuzilish sxemalari Haydalayotgan suyuqlik turiga qarab kanalizatsiya nasos stansiyalari 4 guruhga bo‘linadi: 1. Maishiy oqova suvlarni haydash uchun; 2. Sanoat oqova suvlarini haydash uchun; 3. Atmosfera suvlarini haydash uchun; 4. Cho‘kmalarni haydash uchun Download 0.56 Mb. Do'stlaringiz bilan baham: |
