The Design of low pressure water supply system water jet cleaning equipment.
Abstract: ultra high pressure water jet technology is a technologydeveloped in recent years in the world, the technology is mainly using the kinetic energy of high speed water jet stripping surface stubborn dirt, it is with water as the medium, driven by large flow turbochargerdiesel or turbine, water is pressurized to 40000PSI (300Mpa) the pressure, then through a plurality of nozzles gem circular permutationejected, the nozzle is driven to rotate by a hydraulic or pneumatic,forming a multi beam, multi angle, strength of different ultra high pressure rotating water jet, which need for surface cleaning of equipment, internal fouling and attachment and the blockage of ultra high pressure cleaning. Low pressure water supply system is an important component of ultra high pressure water jet cleaningequipment. Direct drive pump is the main equipment of high voltage,centrifugal pump is the main part of the low pressure water supply system, life is very important for design of low voltage supply systemon the efficiency of the centrifugal pump and the machine. Water jettechnique has the advantage of high technology to improve.
This research is to design C300 ultra high pressure cleaningequipment of low pressure water supply system, to achieve the goalof continuous work in rated condition, its performance is not less thanUH-300 high-pressure pump water standards. The two pump subassembly mainly include two categories: water pump parts and air compressor parts, which includes 1 water pump parts, pump head 2,flange connecting plate 3, copper pagoda and the joint 4, pumpwheel 5, stainless steel inner thread elbow 6, the water pump base;air compressor parts Compressor and compressor wheel and L pumpand pull plate, and they are connected through the multi wedge belt,finally with the diesel engine is connected, water pump and air compressor driven by the power of the diesel engine work. In the scheme, the main purpose of the design is based on the features of the centrifugal pump inlet, considering the realization structure,economic and other factors, so that to maximize the economic and functional effects.
