Tank negative pressure water equipment Overview: The traditional way is inseparable from the water tower reservoir of water is generally supplied from the water pipe network; so; pressure of the water into the pool becomes zero; cause a lot of energy for nothing waste tank !! negative pressure water equipment is based on pressure water supply equipment developed on a direct connection with the water pipe network. and on the water pipe network does not produce any side effects complete water supply equipment without negative pressure tank !! supply equipment replaced the reservoir and rooftop water tanks; tank no negative pressure water equipment to take advantage of the water pipe network, directly or indirectly, water; avoid secondary pollution energy waste and water quality; substantial savings infrastructure investment and shorten the construction period !! tank pressure water supply equipment intelligent frequency conversion control cabinet steady flow tank pump unit base instrument valves and piping and other components;..... applicable to all the needs of increased water pressure. constant flow water supply systems without negative pressure water tank !! Features - tank negative pressure water equipment without energy and resources to build the pool -.. tank negative pressure water equipment significant energy saving effect of economic health practices. prove - using intelligent non-negative steady flow water devices can save energy more than 50% of the cost of the new pool; compared with other water supply equipment; can save 20% to 40% !! tank negative pressure water equipment easy installation savings. covers - tank negative pressure water equipment can configure the horizontal steady flow tank; vertical steady flow can also be configured in two !! steady flow tank has different characteristics - horizontal steady flow can occupy a small space - vertical steady flow can occupy a small area; steady flow tank manufacturing; testing are in line with the provisions of GB150 "steel pressure vessel," the inner wall of the tank using an advanced "841 epoxy polyamide food container wall paint" corrosion. ; safety in line with national food hygiene standards !! tank negative pressure water equipment versatile adaptability - Tank negative pressure water equipment can be used for domestic water supply;. fire water pumps can be configured to any type; when the device is used. Fire at; special pumps should be equipped with fire !! tank negative pressure water equipment features full high degree only - no negative pressure water tank equipment using an advanced human-machine inverter control technology; soft start; overload ..... short circuit over-voltage phase overheat and stall protection function in exceptional circumstances !! signal alarm; self-test and fault diagnosis also automatically adjust the water flow !! tank without water according to the level. advanced negative pressure water equipment and reliable quality - Tank negative pressure water equipment accessories; After screening many manufacturers; with reliable quality assurance; product key components; such as - Motor pump bearings. ... drive short-circuit contactor relays such as the use of international and domestic high-quality brand !! tank negative pressure water equipment installation and commissioning - Basic Figure Construction Tank negative pressure water equipment manufacturers to provide the basis of size shall ; its location and standards should be consistent with the engineering design and TJ231 "on the basis of the size and location of the device quality requirements" !! tank negative pressure water equipment in place after leveling with a spirit level; its vertical and horizontal levels should be less than 0.1% of the tank !! After no negative pressure water equipment installation leveling; expansion of basic secondary cement grouting; maintenance 24 hours before !! tank piping should confirm the direction of rotation negative pressure water equipment after electrical wiring; ensure consistency with the standard arrow !! Tank negative pressure water equipment use and operation - before the tank should be no negative pressure water equipment to move the pump rotor disk; there should be no friction; catching phenomenon !! tank negative pressure water equipment 500V low voltage shake table test motor insulation ; should be more than 0.5M !! tank negative pressure water equipment control instruments and line no damage !! negative pressure water equipment full tank pump inlet valve; close the outlet valve; each pump discharge valve to be opened. After the liquid fills the pump chamber !! tank valve closed negative pressure water equipment will be placed in the manual position switch, load to move the pump; its operation should be directed to the standard arrow !! consistent negative pressure water tank by hand equipment start and stop the pump station; Check the pump operation without anomalies !! tank negative pressure water equipment maintenance and repair - Tank negative pressure water equipment in the system should be put into operation before the clean-up; purge; to prevent contaminants from entering the pump caused equipment damage !! tank negative pressure water equipment pumps should long-term operation in the case of the outlet valve fully closed; nor should run hump at the performance curve; not to air operation; when the seal with packing seal allowed There are 10 to 20 drops / min tank leaks !! negative pressure water equipment running bearing temperature must not exceed 75 degrees Celsius !! tank negative pressure water equipment to deal with bearings in the pump every 500 hours of operation to conduct a refueling !! 5. Equipment shall take the necessary measures to long-term outage; prevent tarnish and corrosion equipment; winter outage should be used antifreeze; Warm !! 6. Run the water quality of the implementation of the device should be considered preliminary sewage !!
