(Non-inverter) automatic pipeline booster pump system classification / principle of differential pressure level schematic automatic pipeline booster pump, the device shown in addition to the accessories, you need to configure the level float switch. Inverter automatic pipeline booster pump (ie variable-speed pump) system diagram booster structure according to different points: Vertical single-stage pipeline automatic booster: Booster GD cast iron pipe vertical single-stage centrifugal pumps, line part defaults steel pipe. Cast iron vertical multistage centrifugal automatic booster: Booster cast iron VP vertical multistage centrifugal or cast iron DL vertical multistage centrifugal pump, pipeline steel pipe section defaults. Vertical multistage stainless steel automatic booster: Booster CRF with stainless steel vertical multistage stainless steel pipeline pump, valve portion may be stainless steel or steel pipe according to actual needs. Note: The above three models Whichever you choose, controllers are using the same paragraph. Divided according to the principle: differential pressure: differential pressure by a common electrical control cabinet, booster pumps, electrical contacts (water protection and pressure settings), pressure tank, check valves, valve, base and other components; use direct tandem on direct pressurized water pipes. Through the electrical contacts pre-set operating range (upper and lower pressure limits), the boot operation, the device starts running pressurized pipeline pressure when the pressure rises to the upper limit of the user preset value, the electric contact pressure gauge the role, immediately shut down the pump to maintain pressure; when the open faucet water pipe network pressure drop, once the low pressure at the pressure limits set by the user, the pump restarts boosting. Reciprocating cycle will reach constant pressure water supply. In special cases, you can use two pumps in turn initiates a switchover. Level type: level style (no frequency) by a common electrical control cabinet, booster pumps, liquid level float switch (level control), electric contact pressure gauge (water protection), check valves, valve, base, etc. composition; when used in series with the water pipe, water pipe through the second pressurized water will be transported to the roof pool / water tower, when the pond / water level in the water reaches the pre-set high level in the float the role of the switch pump stops running, when the user of water caused the water level drops to the lower limit level set in advance, in the role of the pump float switch restarts pressurized water supply. Cyclical continuous water supply purposes. In special cases, you can use two pumps in turn initiates a switchover. Inverter: Inverter by the frequency control cabinet, booster pumps, electrical contacts (from water protection), remote pressure gauge (pressure data feedback), pressure tank, check valves, valve, base and other components. By pre-set constant pressure, remote pressure gauge constantly at work gathering pipeline pressure data and feedback to the controller, real-time adjust the pump speed by comparing the user preset value and the actual pressure value to correct the pressure deviation value, and so they constant pressure water supply purposes. Under special circumstances, inverter-type horizontal booster pump can be used to make an automatic frequency control booster II.

Installation site is not higher than the maximum altitude of 1500 meters, high altitude use should be particularly pointed. Installation gradient does not exceed 5 °. Handling Precautions 1, the device is a strong electrical device should hold a certificate of electrician. 2, the device must be configured in accordance with the maximum power of sufficient capacity wires, and check the power supply voltage, phase, frequency is consistent with the equipment nameplate, the ground is reliable, and connect the cable wiring in accordance with the provisions of law devices. 3, when the initial start using jog mode to ensure proper motor rotation. Single-phase power supply equipment without paying attention to this. 4, the pump transmission medium temperature and corrosive acid salt shall not exceed the scope of this pump is made of. 5, the pump is installed, you must ensure that access to the pipe diameter (including valve diameter) is equal to the pump input diameter, or may appear insufficient water cause the device to not work properly. 6, if the pump inlet pipe mouth fitted with filters, mesh filters must ensure that the total area of ??not less than the pump inlet area, and regular cleaning of the filter, blocked intake or impurity caused by lack of water pump device stops working. 7, during operation, the pump must ensure that the input pipe does not leak, or cause insufficient pressure or no water suction failure. 8, the pump is not appropriate outside its marked head and flow range, otherwise damage to the motor or increased noise. 9, the pump is handling or installation, should be handled with care. 10, the device maximum mounting height (distance from water pump inlet in meters) of the formula: 10.33- must cavitation margin value -1.5 m safety value, the actual installation height values ??as small as possible is appropriate, the maximum shall more than the calculated value, otherwise the pump will cause cavitation suction efficiency is too low or no water, more severe cases can damage the pump parts. 11. Do not attempt to adjust the water protection switch, or the device may be due to loss of water protection damage the pump. Gauge wiring and calibration methods, such as using a multimeter are measuring gauge between two of the three lines, the 3rd largest of any resistance value of the terminals connected to the controller and 5 terminals, terminal 1 connected to the remaining one controller , connected into the system parameters, based on the actual range selection pressure gauge pressure gauge on the controller's range. Take a good line, you must check the gauge wiring methods are correct. Specific detection method as follows: manually open the pump, observe the pressure gauge trends are consistent with the actual pressure value is displayed on the controller, if consensus proves correct wiring; if the value of the gauge is on the rise, and the control panel display Pressure display is on the decline, then prove access terminal 3 and the ground terminal of the 5th line reversed, exchange the two cable. After the wiring is correct, enter the pressure calibration procedure. Specific operational procedures: first manually open Renyiyitai pump, then the gauge readings actually enter into the press to confirm, pay attention to the same value can not be calibrated twice. It represents misuse operation twice, for example: pressure gauge reading after 0.23Mpa enter 0.23 to confirm press ENT. The next time you can not enter calibration is 0.23, you must enter another value recalibration. It is worth noting that, when the pressure gauge at zero pressure state calibration, do not zero, calibrated to a 0.01, or manually play up the pressure after the correction. Troubleshooting Solution 1, when you open the tap, why not start the pump? Whether or pressure-frequency automatic pressurization equipment, provided the work is below the set pressure value will start the pump, if the a little time around the water pipe network, and devices connected to the pipe network pressure enough, then if someone with water, the water pressure is higher than the pressure we set, in which case the pump will not start. 2. Why booster frequent starts and stops? Frequent starts and stops this phenomenon is generally pressure-automatic pressurization device that appears. The main reason for this phenomenon may be the upper and lower pressure setting too close, when the water peak, the device due to pressure changes in the pipe network client start and stop frequently. Solutions to lower due to lower pressure limit. 3, the pressure is below the set value, why not start or pump? This phenomenon may be caused by water protection, especially when electrical contacts as water protection, water pressure when the set value is too high , if the water pressure is so low that is lower than the set pressure value, then regardless of the user enough pressure, pump will not start to play a role in water protection. 4, pool water level is full or the water level in the end, why not stop or start the pump? This may be because the float level switch is wired incorrectly, reference schematics rewire control. 5, no matter how the device is running, the pressure is why the table show zero? Probably because the meter valve was mistakenly turned off or damaged, replace the check valve is closed or the pressure gauge. Q: I am in the end the selection of differential pressure or frequency type A: You can choose the following scenarios pressure control:? Booster pump flow and head are small (as pumps power 4KW or less); water less frequently ( If water is used for fire station is small or temporary water supply). You must select the following scenarios frequency control: the larger booster pump power (4Kw above); and higher lift (above 50 meters); the number of water more frequently (such as multiple stations often water, etc.). Q: GWS series voltage which A:? GWS series are civil and industrial use. You can configure the 220V / 380V needed. Q: What can one with a prepared? A: Yes, differential pressure, level and type can configure a spare pump, can turn up and running at startup; Inverter configure a spare pump is constant pressure water supply BWS equipment.
