Fill in the blank: The connection method between the oil transfer pipe and the vacuum pipe: One method involves running a short pipe from above each crane pipe control valve to connect with ( ), and since it is connected near the quay, it is also known as a quay connection. Its advantage is that it enables a fast siphoning speed for the crane pipes. Another method is to connect ( ) to the oil pipeline at the pump inlet, also known as pre-pump connection; its advantage is that it results in a slower siphoning speed, but it prevents the centrifugal pump from starting with the outlet valve closed. Answer: bilge pump short tube, vacuum tube
Vacuum oil collection pipe, vacuum pipeline,
Connection method between the oil transfer pipe and the vacuum pipe: One approach is to run a short pipe from above each crane valve to connect with the (tank cleaning short pipe). Since this connection is located near the quay, it is also referred to as a quay connection; its advantage is that it enables a fast siphoning speed using the crane. Another method involves connecting the (vacuum tube) to the oil delivery pipe at the pump inlet, also known as pre-pump connection; its advantage is that it results in a slower siphoning speed, but it prevents the centrifugal pump from starting with the outlet valve closed.
