SNGGWG pipe pump without negative pressure water equipment by the negative pressure device, steady flow compensator, SNGGWG silent tube pump, surge tank, intelligent frequency control cabinet, instruments, valves and piping, base Seat and so on, suitable for all need to increase water pressure, constant flow of water supply system. Now to detail SNGGWG tube pump working principle and application of negative pressure water equipment. Pipe in the pump, SNGGWG pipe pump working principle of negative pressure water equipment Pipe in the pump when no negative pressure water supply equipment in normal use, the municipal water pipe directly connected to the steady flow compensator, steady flow compensator water full, no Negative pressure device automatically shut down the steady flow compensator, pressure regulator tank for municipal pipe network pressure, on the basis of mute tube pump frequency control cabinet on the pump speed. Through the pressure sensor, sensing the change of the parameters in the pipe and converting it into telecom volume, transmitting it to the water supply controller. After analyzing and calculating the controller, it outputs the signal to the inverter according to the calculation result to control the pump speed by the inverter so that the water supply system can, Water changes, at any time to adjust the pump speed to water supply. At this point regulator tank filled with high-pressure water and absorb the balance due to user pressure caused by water fluctuations, the water supply more stable. When the water supply Q peak water consumption> Q into the peak water supply, no negative pressure device automatically open the steady flow compensator, tap water to supplement water during rush hour, after the peak period, the steady flow compensator is full of water, turn off automatically Negative pressure device. When the water reaches a low peak, the pressure regulator tank pressure gradually increased to a certain pressure (the pressure value can be set) the entire water supply system into a "dormant" state, all pumps stop working, by the pressure tank high pressure water maintenance system Pipe network water supply. When the amount of water gradually increased, the system will automatically "wake up" quiet tube pump constant pressure water supply to the pipe network. When the municipal pipe network pressure is lower than the user set pressure, the tube pump frequency control operation, to ensure that users of pipe network pressure in line with the requirements of users. Municipal pipe network higher water pressure. The lower the speed of the pump, the lower the municipal pipe network pressure, the higher the speed of the pump. When the municipal pipe network water pressure to meet user requirements, the device automatically stops working, municipal water pipe through the bypass pipe directly to the user. When the municipal pipe network without water, steady flow tank water level gradually decreased, when dropped to the lowest level, steady flow tank on the level gauge to send a stop signal, the device automatically stop running and display water protection signal; when the grid power failure , WFG tube pump no negative pressure water equipment downtime, municipal pipe network water supply directly from the device bypass pipe to the user. Make full use of pipe network pressure and "sleep", "wake up" function to achieve secondary water supply, saving rate of 30-80%, energy-saving effect is remarkable. Second, SNGGWG tube pump negative pressure water equipment applications 1, the new residential quarters, villas, office buildings, comprehensive living building water supply. 2, high-rise buildings, hotels and restaurants and other living water supply. 3, pressure water supply, ground pool pressure and other traditional water supply system transformation. 4, all kinds of boiler cold water supply system. 5, water plant pressure pump station in the middle. 6, the industrial and mining enterprises of production and living water. 7, various types of circulating water, cooling water supply system. 8, tap water pressure can not meet the requirements of life, fire and pressure water supply.

Pins
Brass fasteners are used for their physical and aesthetic properties. Brass is utilized due to its high thermal conductivity and corrosion resistant properties, it is suitable for use in hot and cold environments, and resistant to water corrosion, making it a staple of industries such as heating and plumbing. Brass fasteners are largely non-magnetic (like any fastener, slight magnetic properties can develop during the manufacturing process) and resistant to tarnishing.
Brass fasteners are suited for some marine environments, including brackish water and slow current sea water; brass in this environment develops a protective green coating. Brass fasteners are also commonly used with wood applications, as the golden coloring blends well with the tan wood. Brass is a softer metal and must be used with care, always drilling pilot holes and using driver bits that fit the head of the screw precisely to prevent stripping. Brass Bolts also require a pilot hole be driven before installtion.
