Alfa Laval AlfaNova 14-76, AXP AN Instruction Manual

sure you know which one should be activated first. Note! Adjustments of flow rates should be made slowly in order to avoid the risk of water hammer. Water hammer is a short-lasting pressure peak that can appear during start-up or shut-down of a system, which causing liquids to travel along a pipe as a wave at the speed of sound. This can cause considerable damage to the equipment. Step 1 Check that the inlet valve (2) is closed between the pump and the unit controlling the system flow rate. Inlet valve (2, ...

floor, on feet or on the wall. Larger heat exchangers should be secured with support mountings (ordered as accessory) intended for a specific heat exchanger, or be secured with straps or by means of mounting bolts. Note! Regardless of the mounting method minimize the pipe loads at installation. Maximum tightening torques for the mounting bolts according to table below. Bolt dimension Torque Nm lbf*ft M5 2.3 1.7 M6 3.8 2.8 M8 9.5 7.0 M8 (Extra small units) 8.0 5.9 M10 19.0 14.0 M12 33.0 24.3 UNC 1/4” 3.8 2.8 UN ...

Step 6 Repeat steps 1–5 for the second media. Unit in operation Note! Adjustments of flow rates should be made slowly in order to protect the system against sudden and extreme variations of temperature and pressure. During operation, check that: • media temperatures and pressures are within the limits stated on the name plate • no leakages appear due to faulty tightening of the connections. Protection against connection loads Make sure that the heat exchanger is fastened to avoid or minimize connection loads during ope ...

Sudden temperature and pressure changes could cause fatigue damage to the heat exchanger. Therefore, the following must be taken into consideration to ensure that the heat exchanger operates without fluctuating pressures/temperatures. Warning! The plate heat exchanger is not intended for cyclic processes, please contact an Alfa Laval Representative for advice. • Locate the temperature sensor as close as possible to the outlet from the heat exchanger. • Choose valves and regulation equipment which give stable temperatures/pressur ...

sure you know which one should be stopped first. 1. Slowly reduce the flow rate in order to avoid water hammer. 2. When the valve is closed, stop the pump. 3. Repeat steps 1–2 for the other medium/media. 4. If the plate heat exchanger is shut down for a long period, it should be drained. Also, drain the heat exchanger if the process is shut down and the ambient temperature is below the freezing temperature of the media. Depending on the media processed, rinse and dry the heat exchanger and its connections. Document ...
