Shaanxi, Hunan constant pressure water supply equipment [Walter] Water Equipment Co., Ltd. China Merchants secondary water supply equipment specialists → Hunan Walter welcome your call to discuss business opportunities in wealth constant pressure water supply equipment is a new energy-efficient water supply equipment. It pipeline pressure (or user of water flow) to set the parameters by computer control the output frequency to automatically adjust the pump motor speed to achieve closed-loop pipe network pressure regulator (PID), automatic constant water supply system steady pressure to the set of values: namely, the water increases, the frequency increases, the pump speed to accelerate, the amount of water corresponding increase; when the water was reduced, the frequency decreases, slowing the pump speed, water quantity is reduced accordingly, so to ensure that the water pressure and water efficiency of the user requirements, while achieving improved water quality and water efficiency purposes, "how much water, how much water is available"; using the device without the construction of high water tank, water towers, water quality and no secondary pollution, is an ideal modern construction of water supply facilities. Constant pressure water supply equipment constant pressure water supply equipment consisting mainly of the pump unit, pressure regulator tank, pressure sensors, frequency control cabinet, etc., can always maintain the gauge pressure (ie the user pipe pressure) is equal to the value set by the user . Can be used for general living or production water. The composition of the water supply system are: 1, frequency of water supply equipment and municipal water supply pipe network constant pressure when the water pressure to meet the needs of all pump automatic shutdown. Otherwise, the water supply equipment start-up, increasing the pressure to meet the water requirements. 2 additional small pump or pressure tank, for complete elimination of small flow or zero flow for hydropower consumption, increase aid or assist a small pump pressure tank, when the water pressure is low, the automatic shutdown of the main pump, make small pump or pressure tank run . 3, customized constant pressure water supply equipment can consult Ducor pump. While providing pumps and pump repair and maintenance. Constant pressure water supply equipment operation principle: Tap into the conditioning tank, the tank air from the vacuum eliminator, to be filled with water, remove the vacuum automatically turns off. When the water to meet the water pressure and water requirements, through the bypass valve direct water supply pipe network; when the pressure of the water pipe network can not meet the water requirements, the system pressure sensor (or pressure controller, electric contact pressure gauge ) gives the signal to start the pump from the pump to run. When the water pump, if the water pipe network is greater than the pump flow, the system to maintain normal water supply, water peak, if the water pipe network is less than the pump flow, adjust the tank's water supply as a supplementary source of water still, at this time, by vacuum to eliminate air into the conditioning tank, eliminating the negative pressure water pipe network, water peak period, the system returns to normal state. If the water supply shortage or disruption of water supply pipe network which led to declining water level regulator tank, liquid level controller gives the pump stop signal in order to protect the water pump. At night and a small flow of water through a small expansion tank water pump to prevent frequent start. Constant pressure water supply equipment, basic functions: 1, constant pressure control: stable water supply pressure, and can automatically adjust the pump with the work under each state in the frequency and power frequency according to changes in water, and follow the "first open the first stop." in principle. 2, anhydrous automatic shutdown function: if the water without water for any reason this system will automatically shut down once the water pressure reaches the set value is automatically switched on. 3, constant pressure water supply equipment Pumps state auto adjustment function: In the case of continuous low water consumption, for the protection of each pump is normal, the system will switch the pump timed run. 4, the protection function: a phase, overvoltage, undervoltage, overcurrent, overload, short circuit, overheating, stall protection function. 5, since the instantaneous power failure recovery function: changes due to momentary power outage, automatically resume operation state after the call. 6, constant pressure water supply equipment, water fill pressure, self-cleaning function: water peak, due to the water pressure drops, resulting in runoff for when not on the water, it can guarantee automatic supplement the water, but also makes the storage to get killed Coliform bacteria harmful effects to ensure drinking water meets national safety indicators. Constant pressure water supply equipment range of applications: high-rise buildings, residential area towns, enterprises and other domestic water; various types of industrial water (especially for the production of water requires constant pressure); all kinds of water plants, water supply stations, sewage water plant, airports, stations and other stations and agricultural irrigation water supply system; hot water heating systems and air conditioning cooling circulation system regulator; deep pressure water supply; petroleum, chemical and other industries constant liquid delivery system. Constant pressure water supply equipment installation instructions: 1. Equipment requirements and proper installation Figure, pump temperature not below 0 degrees Celsius, not more than 40 degrees Celsius, the device should be above ground 50-100mm, leaving drains, each pump suction pipe should be separate ground pool plus gate for maintenance. 2. Install minimize the use of the elbow, to reduce unnecessary losses. 3. After the equipment has been debugged factory technicians, specialized management personnel responsible for the delivery of the user, special fire-fighting equipment, strict management system must be customized to meet a fire had started immediately. Constant pressure water supply equipment Features: Energy: The device and other control systems, its minimal energy loss, pumps absorb energy only when the requirements of the water, at the time from zero to a maximum of different flow requirements, by changing the speed of the pump , so that it always outputs a constant pressure. In water is extremely small, such as at night, the system can be pressure tank water supply, or auxiliary pump (optional supply design low noise operation: the need to supply the maximum flow of time, and most of the time the pump is working at low speed state and the pump is driven by a low-noise low-speed operation of the motor system also added a set of shock absorbers reduce vibration and noise, suitable mounting can be reduced to a minimum of noise. Thus, the requirements of installing the system in a quiet environment is necessary places such as hospitals, theaters, broadcasting building, residential areas, hotels, etc. Small footprint: require the installation site is very small, flexible layout and special design can be used every possible place to install easy to install: Each set of equipment is complete supply, and has assembled inlet and outlet connections, power and low water protection switch interfaces and operating equipment running economy: Use frequency stepless speed regulation system can quickly adjust the water flow of the pump, and to provide proper water pressure. Suitable operating pressure makes the device a long time, and pumps, valves, meters and other plumbing equipment wear and tear is small, easy to damage. standardized components and can greatly reduce the amount of interchangeability . Spare parts fast return on investment: the higher investment costs will be due to lower energy consumption in the short term compensated significant energy savings can quickly recover the investment costs Agents basic conditions: 1. highly recognized Walter company's development philosophy, willing to work with us together to create a great cause. 2. love to drainage, water supply industry sales career, have a good working attitude. 3.
