No negative pressurized water supply equipment

Price secondary pressurized water system modeling Description: secondary pressurized water system modeling is based on the user water pipeline water pressure and flow to the actual height of the building to the actual water consumption data to determine the secondary..... ... pressurized water table with the regulator device is the next volume of water flow to meet the requirements in accordance with the situation estimated if the water pipe is very thin water flow can not meet the water requirements of the peak of the secondary pressurized water system using the following formula: V Volume = (Q -Q carry out) △ t ??Q = maximum daily intake of tap water into the water peak Q = one day out of the water the highest peak of the largest users of water water peak t = duration of secondary pressurized water supply equipment technical indicators: 1 secondary pressurized water system water flow 0-1500 M3 / H head 2, the second pressurized water supply means for controlling the motor power 0.75 --- 1500KW 3, the second pressurized water supply households 10-10000 household device 4, two secondary pressurized water system pressure control range 0.15-1.6MPa 5, the second pressurized water supply means the average saving rate 30-60% of secondary pressurized water supply equipment installation and maintenance 1, the installation should choose a well-ventilated, low dust not wet the site, environmental humidity -10 ℃ -40 ℃. Should be fortified in the outdoor rain, lightning and other facilities. 2. To facilitate the equipment around the installation, maintenance, equipment, space should be left 70cm, manholes should be retained 1.5m space, surrounded by floor drains should be located. 3. After selecting the venue, properly handle the foundation, with concrete pouring or masonry tank bearing seat. After the base is fully cured, then lifting the tank and put stability, followed by installation accessories, power. 4, before the test, you should turn off the water supply valves, check valves of the seal, does not allow leakage phenomenon, after driving, you should pay attention to the steering pump. When the pressure gauge pointer to the upper limit, the pump automatically stops. Open the water supply valve to the normal water supply, for regular water supply, you can pull the selector switch to the manual position. 5, the device should always check the pump unit. Centrifugal pumps and check valves found leaking, tighten the flange bolts should be timely replacement of asbestos or root, check the pump can not loose foot bolts to prevent damage to the machine. 6, electrical automatic control system, should be waterproof, dustproof, always check the wiring insulation, connecting bolts are loose and the fuse is good and so on. External pressure gauge is best to use a transparent material wrapped to prevent damage. 7. paint off the tank if found, should be promptly painted maintenance to prolong life. Secondary pressurized water supply equipment, generally located on the floor or basement. There are water units, the use of the device can schedule the peak water consumption, increase water pressure during peak water can meet the large area of ??water and a high floor with water. No running water units, factories or villages, just the equipment connected to water supply, you can get a stable water pressure to meet water needs. Secondary pressurized water system from the pressure tank, pumps and electric control system, some three, whose outstanding interests, without creating towers, small investors, small footprint, active organization, put into operation quickly. Selection of water vapor automatic scheduling, automatic operation, automatic saving and water grid, water supply even after a power failure, after debugging without guards. Widely used in business units, producing vertical water tower residential areas and villages, the day, the job supply. Applies to water users within 5000, daily water supply within the 3000m3 premises, water height of 100 meters or more. Kaifeng no negative secondary pressurized water supply equipment selection pressure water supply system. The use of sealed tanks, using high-pressure gas tank to supply water pressure to arrive purposes. Specific job sequence by the water pump pressure into the tank through the check valve, the gas tank was so tight, pressure increases. When the pressure arrived at the designated limit of the electrical contacts on the control cabinet by the pump automatically after another. Equipment hydraulic pressure in the pipe is higher than outside, automatic bottled water to the water supply network. When the water level in the tank body drop, constant pressure water supply tank of gas swell pressure is reduced to a specified limit position, the electrical contacts through the control panel so that the pump restarts. Repeat to make continuous water supply equipment. When the gas tank is missing, fill valve automatically qi. Secondary pressurized water pressure water supply installations. Use of sealed tanks, the use of high-pressure gas tank to supply water pressure purposes. Specific work order by the water pump pressure into the tank through the check valve, so that the gas tank is compressed, the pressure increases. When the pressure reaches a specified limit on the electrical contacts through the control cabinet pump automatically stops. Equipment hydraulic pressure in the pipe is higher than outside, automatic bottled water to the water supply network. When the water level inside the tank down the gas tank swell pressure is reduced to a specified lower limit position, the electrical contacts through the control cabinet so that the pump restarts. And so forth, so that the device kept the water supply. When the gas tank is low, fill valve automatically qi. Vertical series of secondary pressurized water supply equipment tonnage of 2-20 tons, the Department of vertical water supply equipment, has a small footprint advantages to doing well or cistern water, suitable for a small area of ??ground, less water users . Horizontal series of secondary pressurized water supply equipment tonnage of 10-100 tons, Department of horizontal supply equipment to do well or cistern water, suitable for enterprises and institutions, rural and other large water users. Secondary pressurized water system pressurized water developed a new generation of Loudi secondary pressurized water through the pump shaft rotates the drive motor, rotating impeller accelerates the water, the water pressure, with frequency control to achieve constant pressure water supply, and with regulating valve to achieve constant pressure water supply compared to 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. Generally speaking, when an inverter control by an electric motor, just to make the drive motor capacity is consistent with the actual capacity of the motor can be. When an inverter simultaneously control two motors, in principle, with the drive motor capacity should be equal to the sum of the two motor capacity. However, if at the time of peak load water supply quantity than two pumps at full speed a lot of difference, may consider appropriate to reduce the capacity of the inverter, it should be noted that there is sufficient capacity. While the pump is running at low speed, the motor current is small, but when the user's frequent water changes, the motor will be in frequent acceleration and deceleration state, acceleration and deceleration of the current can be slightly more than the rated current of the motor , causing the motor to overheat. Therefore, the motor thermal protection is required. This temperature rise due to frequent acceleration and deceleration and accumulated, electronic thermal protection function within the inverter is difficult to play a protective role, it should be used for the motor thermal relay thermal protection. In the main function of the preset, the highest frequency should be based on the rated motor frequency for the maximum operating frequency of the inverter, acceleration and deceleration time in the case of the PID regulator, the acceleration and deceleration time should be set shorter, so as not to affect the dynamic response of the PID regulator decision. Such as the drive itself has PID adjustment function, simply set the preset PID function is active, the set-up and spin-down time will automatically lapse.
