Jilin no negative pressure water equipment, Walter da Meng Meng meaning of life, Jilin no negative pressure water equipment manufacturers, the changes do not care about the outside world, and it is the quality of care. Walter -------- ------------------------- For more information, please contact Walter Hunan Water Equipment Co., intimate adviser: I smiled Zhang Qi Qi O O six hundred thirty eight forty Address: Changsha High-tech Development Zone, Lu Tin Road on the 8th floor, Oak Park 5 1 ------------------ - Meng Meng Da ------------ Jilin negative pressure water equipment by changing the input power to the AC motor frequency, so as to achieve the purpose of adjusting the speed of an AC motor. No negative pressure water supply equipment pumps water systems are generally designed according to the maximum demand conditions to consider, and water systems in actual use, do not necessarily have a lot of time to reach the maximum amount of water, generally increases with valve control system resistance to the throttle, causing the loss of electrical power, while the use of the inverter allows the system to work flat and stable state, by changing the speed to regulate the water supply, and energy-saving return on investment by reducing the rotational speed. Jilin no negative pressure water device is a pressurized municipal water supply network connection, a residual pressure in the municipal pipe network overlying water supply based on tandem and ensure direct municipal pipe network pressure is not lower than the set pressure to protect the water supply unit (may be relative pressure zero pressure, pressure is called negative pressure is less than 0) secondary pressurized water supply equipment. Jilin to use negative pressure water equipment: Before the trial, you should turn off the water supply valves, check valves of the seal, does not allow leakage phenomenon, after opening, the steering pump should be noted. When the pressure gauge pointer to the upper limit, pump automatically stops. Open the water supply valve to the normal water supply, for regular water supply, can pull the selector switch to the manual position. During use no negative frequency of water supply equipment, the user's water consumption is constantly changing, so there occurs insufficient or excess water supply situation. Imbalances between water and water concentrated reflection on the water supply pressure, that more water and less water, the pressure is low; less water and more water, the pressure. To maintain a constant water pressure, you can maintain a balance between water supply and water, that the water for a long time too much water, too little water came from water, thus improving the quality of water supply. Categories Jilin no negative pressure water equipment: First, according to water supply points: (1) constant pressure variable water supply system: the pump outlet pressure is always maintained at a constant value, the water supply device can be varied needs of water users varies. (2) a variable transformer supply system: control the pressure sensing point of the system is located at the end user's water supply system, measured by this pressure to control pump operation speed at which the pump outlet pressure is changed, the user is also a change in water a. Second, according to the control points: (1) computer control type: control of the core by a single chip. (2) PC-control: control of the core by a programmable logic controller. Third, divided by number of pump units: (1) Single desktop: a pump speed control operation, another pump spare, two interchangeably. (2) Multiple parallel: a pump speed control operation of multiple frequency operation. Through the establishment of a sound service system, to provide high-quality water supply equipment, but also provides dedicated, high-quality, personalized service to customers. Service planning and service projects into service commitment of two parts. First, the purpose of service: customer focus, commitment to customer service and customer satisfaction. Second, our service commitment: 1, where to buy our water supply equipment customers, if demand our technical staff will provide home visits for free installation and technical training; in water supply equipment to meet the customer's site to complete the installation and commissioning of three days. 2, Division I for the sale of water supply equipment for a period of 12 months warranty. The warranty period, the company free treatment of non-human factors and the quality of the equipment itself belongs to occur under normal conditions of use. 3, Division I for the sale of products to provide maintenance services for life. Ensure long-term spare parts supply equipment at preferential prices to ensure supply for at least 10 years. ------------------------- Walter Hunan Water Equipment Co., Ltd. welcome all friends to visit, guidance and business negotiation.
