Tank overlying water supply equipment, overlying water supply equipment, the construction of water supply

CCT negative pressure water equipment, the largest production base of five provinces in central, welcome to consult in the construction ZJWF super negative pressure water equipment is the latest performance PID frequency control and two pumps connected in parallel over the tip of pressurized water supply equipment, can automatically adjust to meet the user's constant pressure variable water requirements. Water supply network pressure remains constant, the entire water supply system is always best energy efficient. The level of dual-chamber negative pressure water equipment to install? In the construction of water supply equipment to teach you the level of dual-chamber basis of the drawings negative pressure water equipment foundation size should be provided by the manufacturer, its location and the standard should be consistent with the engineering design and TJ231 "on the basis of the size and location of equipment quality requirements." the level of dual-chamber negative pressure water equipment in place after a level leveling, the aspect level should be less than 0.1% after the level of dual-chamber negative pressure water equipment installation leveling, with expansive cement on the basis of secondary grouting. Maintenance 24 . hours after the twin-level piping should confirm the negative pressure water equipment electrical wiring direction of rotation, to ensure consistency with the standard arrow height twin-negative pressure water equipment and operation - before equipment should Barring pump rotor should be no friction, hysteresis phenomenon --500V shake table to detect low voltage electrical insulation, should be more than 0.5M. - instrumentation and control circuit without damage - full pump inlet valve, close the outlet valve, one by one Open the pump discharge valve, until the liquid fills the pump chamber close the valve - the switch in the manual position, no load to move the pump, its operation should be consistent with the standard arrow direction - one by one manually start and stop the pump ., check the pump operation without abnormal level of twin-how to maintain negative pressure water equipment; the use of non-negative pressure water equipment is how to maintain it? - Equipment put into operation before the system should be cleaned purge to avoid impurities entering the pump equipment damage. - The pump should not be long-term operation in the case of the outlet valve is fully closed, nor should run at the performance curve hump, but not to air operation, allowing the seal with packing seal when there are 10 to 20 drops / min leaks - Runtime bearing temperature must not exceed 75 degrees Celsius - the water pump cope with bearings in the once every 500 hours of operation refueling - equipment long-term outage should take the necessary measures to prevent equipment contamination and corrosion, winter outage should be used antifreeze, precautionary measures - operation of the equipment should be considered preliminary implementation of sewage water quality.
