Question

Accepted Answer

Answering questions related to confined space job, alignment of pump and motor, types of gaskets and valves, and troubleshooting reciprocating compressor.

Safety watch is responsible for monitoring the workers inside the confined space and ensuring their safety.
Alignment of pump and motor can be done using dial indicators or laser alignment tools.
Different types of gaskets include spiral wound, ring joint, and sheet gaskets. Different types of valves include gate, globe, ball, and butterfly valves.
Reciprocating compressors can experience issues such as valve failure, piston ring wear, and cylinder scoring. Troubleshooting involves checking these components and adjusting as necessary.

1st answer 
With this function, you can monitor your employees' movements in real-time while they are in the field, which is essential for ensuring their safety and tracking when they work alone in isolated or high-risk environments.Pump alignment is necessary for the pumps in numerous industries like oil refineries, water-treatment plants, power plants, and many other manufacturing facilities. Like any other indispensable machinery part, pumps ensure that the processes flow uninterrupted and remain efficient and reliable. Even so, achieving optimum performance depends on a crucial aspect: a properly aligned pump.

In this blog, let us examine the consequences of pump misalignment and see practical guidance on detecting such issues. We will also discuss the best practices for maintaining optimal performance and avoiding downtime.this was the go to method of accurate shaft alignment. To use this method, we clamp a dial indicator onto the shaft of the motor, then run the measuring pin on the coupling on the pump. As we rotate the motor, the pin will move up and down showing where the high and low areas are in both planes.

Gasket's are usually made from a flat and flexible sealing material. There are many types of material for different applications. Common materials include cork, rubber, non-asbestos fibre, graphite, silicone, paper, PTFE, shim and many more.
These valves used in power plants work to prevent over-pressuring, to keep people, the plant, and the environment safe. Shut Off Valves. Also known as isolation valves, these are usually ball valves, gate valves, and butterfly valves. They stop process media from moving to a location and help control its path.
4th answer 
If the sound comes from the compressor itself, check the oil level first. If the sounds appears or disappears at a certain level, check the inlet/outlet valves, piston rings. If it is a knocking type sounds, you may have a problem with your main bearings or connecting rod bearings. The oil must go somewhere.
