Air-cooled heat pump installation skills
Air-cooled heat pump installation tips: 1. Air-cooled heat pump installation technology key lies in determining the air-cooled heat pump installation height (ie suction). This height refers to the vertical distance from the water surface to the centerline of the air-cooled heat pump impeller. It can not be confused with the allowable suction height. The allowable suction height indicated on the product manual or nameplate of the air-cooled heat pump refers to the air- Type hot oil pump inlet cross-section of the vacuum value, but also at 1 standard atmospheric pressure, the water temperature of 20 degrees Celsius, the test was measured and determined. It does not consider the condition of the water flow after the water supply pipe is matched. The air-cooled heat pump installation height should be allowed to suck the vacuum height deducted after the suction pipe loss lift, the remaining part of the value, it is necessary to overcome the actual terrain water absorption height. Asphalt heat pump installation height can not exceed the calculated value, otherwise, air-cooled heat pump will not pump water. 2. The impact of the calculated value is the size of the suction pipe lift loss lift, it is appropriate to use the shortest pipe layout, and try to install elbows and other accessories, but also consider the appropriate larger diameter pipes to reduce the flow rate within the pipe. 3. It should be noted that the zyb booster pump installation site elevation and water temperature is different from the test conditions, such as the local elevation of 300 meters or pumping water temperature exceeds 20 degrees Celsius, the calculated value to be amended. Ie atmospheric pressure at different elevations and saturated vapor pressure above 20 degrees Celsius. However, when the water temperature is below 20 degrees Celsius, the saturated steam pressure is negligible. 4. From the pipeline installation technically, the suction pipe requires strict sealing, can not leak, leakage, screw pump or it will undermine the air-cooled heat pump intake at the vacuum, the air-cooled heat pump to reduce the amount of water In severe cases, they can not even pump water. Therefore, we should conscientiously do the work of the interface of the pipeline to ensure the construction quality of pipeline connection.
