Precautions for hydraulic ejectors
Thread Content
Precautions for hydraulic ejectors (1) In the cold water inlet pipeline from the booster pump to the ejector, the number of fittings should be minimized to reduce resistance losses. (2) The drain pipe must be vertical with no bends; if bending is necessary, the angle of bend shall not exceed 45°, typically 30°, and there shall be no more than two bends. (3) All interfaces must be tight to prevent leakage. (4) During installation, the user should prepare a section of steel pipe according to the diameter of the outlet pipe of the diffuser as a tail pipe; its length should generally be over 2 meters, but it must not extend into the water in the circulation tank. (5) Fault: The vacuum level cannot be achieved. Reasons: Leaks in the pipe connections during installation, clogged nozzles, insufficient flow and pressure from the water pump, and a malfunctioning vacuum gauge.
Hydraulic ejectors – not used very often these days, right?
When installed at a low level, the tail pipe must not extend below the liquid surface to prevent fluid accumulation in it under high vacuum conditions; when installed at a high level, the tail pipe should extend below the liquid surface, with the installation height being greater than 10 meters
