Yuxi secondary pressurized water supply equipment Equipment Co. Walter national investment agency, secondary water supply equipment sailing toward the beautiful areas of the reservoir-type secondary pressurized water supply problems in the first, the use of reservoir water supply energy waste. Using reservoir water supply pressure must be remaining municipal pipe network is completely let go, the water had become zero pressure with pressure, and then the second pressurized water supply equipment pressure from zero again. In this process, the residual pressure in the municipal pipe network let go all in vain, resulting in waste of energy. For example in terms of a seven-story residential, municipal pipe network pressure to have about 25 meters the user, to meet the water requirements of five-story, six less pressure. In addressing this problem of water shortage, the use of secondary pressurized water supply equipment reservoir water supply when the water supply system is to build a cistern or water tank, plus a pressurized water supply frequency control devices. Their work is: water from the reservoir by the frequency pressurized water supply equipment, pressurized water pipe network to the user with. The above way, the final 31 meters of water pressure, an increase of only 6 meters than the original municipal pipe network pressure. The same situation, if the pipe network overlying negative pressure water supply, you can simply choose to lift six meters of water pump problem satisfactorily resolved. In order to increase the pressure but with a 6 m 31 m lift pump pressure, wasting up to 80.65%, and these losses will ultimately be borne by the user! Secondly, there is no secondary pressurized water supply equipment type of water supply reservoir pool secondary pollution, can not guarantee the quality of the health requirements, causing residents drinking water health hazard. Municipal drinking water supply pipe network through multi-level processing, can basically meet the quality requirements of domestic water, but after reservoir storage, water has been contaminated. Survey shows that the use of reservoir-type secondary water supply system, the majority of water quality failure, CL remainder is zero, all kinds of harmful bacteria seriously overweight. More seriously, the reservoir can not be avoided, and other debris into the mice, and the pools, water tanks become a source of disease transmission. In Guangdong and other places, endangering bloodworms particularly severe in the pool, has seriously affected the water security of the user. Third, the use of the pool is likely to cause run, run, drip, leak, evaporation and other phenomena occur, causing the user to increase the cost of water, the abolition of the reservoir, water tank can save water, fresh water resource in today's increasingly tight, water conservation is already a serious and urgent requirements. Miss Liu 13874905205 ??Fourth, the use of the reservoir's water supply in the water supply system in the presence of an open link to the poisoning of drinking water to provide a convenient conditions for the crime, in fact, not uncommon cases of poisoning drinking water reservoirs, resulting in drinking water source of security risks. Fifth, covering more costly. Use reservoirs (tanks), an area of ??large, complex construction, long construction period, so that the cost of construction of water supply systems increased by 40 to 60%. Especially for the renovation project in terms of re-construction of reservoirs in the old town is very difficult, which is the root cause of a lot of hard water problems. Finally, the water supply links, float valve, pump bottom valve, water level controller, etc. are failure-prone areas, making equipment, poor stability, high failure rate, equipment maintenance workload, short life, management difficulties. In addition, such equipment running noise, there is environmental pollution. In short, the use of a secondary reservoir-type pressurized water can not meet the needs of the community, in terms of energy, water, land, health or environmental pollution from the perspective of, can no longer meet the needs of users, the reservoir has been canceled become the consensus of the community, it is imperative! With the development of the social and economic advancement of technology, municipal water systems to gradually improve the water quality standards, water supply capacity is growing. In order to meet the requirements of social development, automatic water supply equipment secondary pressurized water supply equipment inevitably towards a certain goal, the goal is energy efficient, no water pollution, low noise, easy to operate, reliable operation. Secondary pressurized water supply equipment directly to the municipal pipe network for water, to form a continuous closed relay pressurized water supply, water quality standards completely avoid the traditional 2 pressurized water system caused by the reduction and a variety of water pollution problems, fully maintained municipal water quality standards for full use of municipal water pressure heat much difference how much, effectively, maximize the energy saving effect of frequency control. Equipment Field Notes: 1. Before commissioning should have the conditions: control cabinet should be installed in a clean, dry, no dripping occasions, and non-corrosive or conductive dust (protection level 2), should do all kinds of protection work. Requirements for three-phase power line five-wire system, voltage requirements: 380V (± 10%), is under way into the cabinet into the wire, the zero line, PE lines are insulated against the zero line terminals, ground copper rafts ; three phase cable to the top of the open space on the total required crimping copper fittings, rinse tin processing requirements securely. Electrical wiring in prefabricated pipe must be worn before, according to plant. Wear tube map design unit home or laying threading tube, pipe must be a certain distance above the ground and pre-set wire, connect electrical lines, signal lines required to guide the installation commissioning . Pipeline before docking device must be rinsed before commissioning must be an ample supply of water, the pump can not load debugging, otherwise damage to the equipment. When using temporary power commissioning, on-site must hit the ground pole, take a good ground, reversing the need to manually replace the formal transfer power. 2. Run the attention: the control cabinet should be placed vertically mounted on the control cabinet stable foundation or channel base. Within the first cabinet after the main switch is closed, then the control power pole switch is closed, in order to carry out the manual and automatic operation of the device. Equipment is running, non-operating "Auto / Manual" switch. Only when the device is completely stopped, before operating the switch. Buck started using auto equipment, non-frequent start, otherwise it may cause damage to the equipment. Inverter and control cabinets housing must be grounded. Do not operate power inverter charged after power off, wait 5 minutes, until the intermediate circuit capacitors discharge and then the drive, motor or cable operation (best to wait after the inverter power LED off three minutes). Must be made by professionals in the equipment repair and maintenance. Equipment overhaul, should control cabinet line supply cut off. To regularly clean the dust cabinet, the cabinet's clean. Unscheduled inspections cabinet grounding screw, ensuring a reliable connection. Fire service equipment must be "manual / automatic" master switch on the front panel to play the automatic position, so that the device is automatically carried out inspection of fire, and when you receive a signal fire automatically start the fire pump. 3. abnormal phenomenon should be noted: the device has the function of automatic operation, if the fault can not be automatic when an alarm, emergency water can be taken manually, time not too long (and someone on-site monitoring pressure), and other plants home maintenance personnel. were handled. No trained staff do their own maintenance, or it may result in serious consequences.
