In the petrochemical, water treatment, and chemical processes, centrifugal pumps are undoubtedly the "model workers", but did you know? 90% of pump body failures, motor burnout, and seal leakage accidents are not caused by equipment aging, but by a small mistake in start stop operations.

As a professional manufacturer specializing in fluoroplastic pumps and centrifugal pumps for many years, Anhui Wolong Pump Valve has seen too many equipment damages caused by non-standard operation. Today we will explain the standard start stop operation specifications for fluoroplastic centrifugal pumps in detail, helping you to guard the first line of defense for equipment safety, so that every Wolong pump valve equipment can operate stably and have a full service life!

Whether it is a fluoroplastic centrifugal pump or a conventional industrial centrifugal pump, the key to operation is hidden in this mnemonic: pump exhaust → disc inspection → close the outlet and start the machine → slowly open the outlet → close the outlet and stop the machine; This is the "lifeline" of a centrifugal pump. If it jumps or reverses, it can cause the motor to trip or the pump to be scrapped!

1. Before starting up: extinguish the "hidden dangers" first; Pump exhaust, strictly prohibit idling, there is air in the pump chamber, not filled with liquid, and once the pump is turned on, dry friction occurs, and the mechanical seal burns out in a few minutes! Manual turning, do not force open, use your hand to turn the coupling 3-5 times, especially when conveying media that are prone to crystallization; If there is no movement or abnormal noise, do not forcefully turn on the machine! It is highly likely that the rotor is stuck or the dynamic and static ring surfaces of the machine seal are stuck, causing direct damage to the impeller or machine seal, and even damaging the bearings. The auxiliary system should first use cooling water, lubricating oil, and sealing flushing fluid, and start 10 minutes in advance to ensure stable oil temperature and water pressure.

2. At startup: Stay steady, don't worry; The inlet valve must be fully open, and the outlet valve must be fully closed! This is called 'closed start', which can significantly reduce the starting current and prevent motor overload tripping. First, tap to confirm if the pump's direction of rotation is correct, especially for the variable frequency motor, check if the coupling's direction of rotation is consistent with the pump's direction of rotation. Wait until the outlet pressure stabilizes, then slowly open the outlet valve while keeping an eye on the current. Do not exceed the rated value, and only release it if there is no abnormal noise or leakage.

3. Running: Focus on 3 key data points; Bearing temperature: Sliding bearings should not exceed 65 ℃, rolling bearings should not exceed 70 ℃, and overheating will quickly burn out. Sealing leakage: The dripping should not exceed 3-10 drops per minute. If there is too much leakage, it should be checked as soon as possible. Oil level: Keep the lubricating oil at 1/2-2/3 of the oil level, do not run out of oil, and do not use spoiled oil.

4. When stopping the pump: the order is wrong, and the equipment is directly "damaged internally"; Slowly close the outlet valve first to prevent the backflow of high-pressure liquid. Turn off the motor power again and wait for the pump to completely stop. Finally, close the inlet valve.

Having mastered the standard operating procedures, it is even more important to be vigilant about high-frequency misconceptions in operation - avoiding pitfalls! Don't make these 5 high-frequency mistakes!

In order to facilitate everyone to quickly master the core of safe operation of centrifugal pumps, we have specially summarized the "three checks and three don'ts" principle, which must be strictly followed: ✅ Three checks: check whether the exhaust of the filling pump is complete, check whether the turning status is normal, and check whether the auxiliary system is in place; ❌ Three Nos: Do not idle, do not reverse, and do not use inlet valves to regulate flow.
