Frequency control water supply manufacturers

 Frequency constant pressure water supply equipment manufacturers Walter Investment Co., the national agency, secondary water supply equipment sailing toward the field agents Fairview basic conditions: 1. highly recognized Walter company's development philosophy, willing to work with us to create great cause together. 2. love to drainage, water supply industry sales career, have a good working attitude. 3. There is a good social relationship or have their own marketing team, with good development potential market credibility 4. good operating conditions stable company priority. 5. voluntarily accept and comply with the company, "agency agreement" by the provisions. 6. With rich resources given priority. Features frequency control water supply: 1. First-saving, intelligent frequency conversion control technology, do not do useful work, and the second, full use of the remaining head of the district, and the device is directly connected in the water pipe network, make full use of the water pipe the original pressure network, comprehensive energy-saving up to 50%. 2. The water-saving frequency control water supply fully enclosed structure run, complete elimination of the run, run, drip, leak water waste, the Research Institute for the nine regions 186 user survey estimates, integrated water-saving up to 13% the above. 3. supply reliable, stable and fully enclosed water pressure, no floor flooded danger; high performance partial pressure regulator, pressure independent real-time adjustment of each district to ensure that the district partial pressure, constant water supply. 4. Water repeatedly to eliminate pollution, water quality high frequency control water supply with a fully enclosed structure, directly connected in the water pipe line, connecting the districts are also closed, no pool, no middle of the tank, not the air contact, completely solve the problem of high-level contaminated water several times. Frequency control water supply all food-grade stainless steel polished production, health and safety. 5. saving investment frequency control water supply directly connected in the water pipe line, do not build the pool, but do not set up the tank in the middle floor, lower overall investment. 6. save administrative costs intelligent automatic frequency control water supply operation, without staff on duty. Because there was no pool, water tank, so do not wash, no disinfection, maintenance-free, maintenance-free, saving management costs up to 95%. 7. Long life equipment automatically adjusts the frequency control water supply control operation based on the use of water, water hammer, no impact, wear, and equipment used in food-grade stainless steel polished production, non-corrosive, extended equipment life up to three times more . Water Supply frequency inverter control principle: Frequency control to achieve constant pressure water supply, compared with using the regulating valve to achieve constant pressure water supply, energy-saving effect is very significant (can be calculated depending on the circumstances). Its advantages are: 1, the starting balance, starting current limit within the rated current, thus avoiding the impact on the grid at the start; 2, the average pump speed is reduced, thereby prolonging the life of pumps and valves; 3 can eliminate water hammer effect starting and stopping; how to install the frequency control water supply: 1, the installation of frequency control water supply piping reasonable amount shall not be allowed on the pump, the pump in order to avoid distortion, affecting the normal operation . 2. Install the inverter should be carefully examined in the presence of a hard object pump abortion before pressure water supply, in order to avoid damage to the impeller and the pump is running. 3, tighten the bolt, so as not to affect the performance of the pump vibration when starting. 4, in the inlet and outlet piping pump installation control valve, pressure gauge installed in the vicinity of the pump outlet to control the pump operates within its rated operating conditions to ensure the normal use of the pump. 5, the discharge pipe loaded check valve should be installed outside the gate. 6, mounting frequency control water supply pump into rigid coupling installation and flexible connection installed. Frequency control water supply generally consists of a buffer tank, water pump, pressure tank control cabinet and control instrumentation components, each part as follows: a, buffer tank: It is connected to the frequency control water supply at the entrance to the pressure tank, referred to as buffer tank, water tank runtime partial volume of compressed air, compressed air energy storage depend on a variety of mutations have a good impact mitigation to eliminate the role, while the municipal water supply has a dynamic compensation. There are two different structures of the buffer tank, buffer tank with natural rubber diaphragm membrane material, due entirely closed more conducive to maintaining water quality standards, ordinary steel buffer tank wall coated with anti-corrosion coatings meet the health standards, but the qi with the outside world exposed to the air. Buffer tank can be connected in series, can also be connected and use (out of the water for the same pipeline, as a branch of the municipal pipeline phase, as shown in Figure 2-2) b, the pump unit: Chengdu has chosen a non-overload characteristics of the pump changes in pressure, which operating characteristics can be adapted to a wide range of water, does not produce overload. c, pressure tank: its role and usually twice a pressurized water supply equipment in the pressure tank, including this series of frequency control water supply standard products using micro diaphragm pressure tank, the main advantage of its packing function, is conducive equipment intelligent automatic energy-saving control. d, frequency control cabinet: frequency control water supply can be full-frequency control system, that all pumps are used in frequency control drag, but also be part of the frequency control system (only a sample of standard products for frequency control drag pump move). e, a bypass line: If the municipal water supply to meet the pressure requirements usually, only the peak pressure in the water supply shortage, loadable bypass pipe, can drop down the municipal water and pressurized water to achieve automatic switching operation.
