Check the piping of the pump – what are the problems? Active participants who answer correctly can be rewarded with 5-10 wealth points. There is no answer; the more carefully a problem is identified, the better. Let’s improve together and make progress together. Chemical Equipment and Machinery
1. The arrow on the globe valve body is in the wrong direction. 2. The materials of the pipe fittings are not compatible. 3. No grounding wire was seen
At the pump outlet, a check valve should be installed first, followed by the valve; the vent valve and pressure gauge should be placed between the pump outlet and the valve
1. The arrow on the globe valve body is in the wrong direction. 2. The materials of the pipe fittings are not compatible. 3. No grounding wire was seen
1. The length of the bolt protruding from the nut is insufficient. 2. The pump bracket is not securely fixed (using expansion bolts), and too much of the bolt is visible. 3. The pipe brackets are not firmly secured using expansion bolts
The bolt heads of the flange connections are not exposed by even half a centimeter; the pump lacks a grounding wire, and the check valve and globe valve should be installed in reverse positions.
The check valve should be installed between the globe valve and the pump, while the pressure gauge and vent valve are placed at the pump outlet
Only one is visible: the drain ball valve is facing downward
The pressure gauge nozzle is installed too high, making it difficult to operate
Can a check valve be installed this way? It should be installed in parallel, I guess. Can an outlet pressure gauge be installed after the valve?
