How to determine if the diaphragm of a low-pressure coal slurry pump has ruptured? How should it be avoided? Answer: When the diaphragm of a low-pressure coal slurry pump ruptures: (1) The pressure at the pump outlet fluctuates frequently ； (2) The corresponding oil filling light remains on the control panel ； (3) When the oil level in the drive fluid tank drops to zero and the crack in the diaphragm is large, coal slurry enters the drive fluid tank. Based on the above phenomena, it can be determined that the diaphragm of the low-pressure coal slurry pump has ruptured; the pump should be stopped immediately for handling. To prevent the diaphragm of the low-pressure coal slurry pump from rupturing, it is necessary to strictly control the liquid level in the discharge tank and avoid emptying it; at the same time, it is important to prevent metal objects from entering the coal slurry. Any blockage in the diaphragm chamber must be addressed promptly. Proper exhaust handling should be carried out in a timely manner; the machine should be stopped promptly when the horizontal bar is not in use

When the diaphragm of a low-pressure coal slurry pump ruptures, ① the pressure at the pump outlet fluctuates frequently, ② the corresponding oil indicator light on the control panel remains lit continuously, and ③ the oil level in the drive fluid tank drops to zero; when the crack in the diaphragm is large, coal slurry may enter the drive fluid tank. Based on these phenomena, it can be determined that the diaphragm of the low-pressure coal slurry pump has ruptured; the pump should be stopped immediately. To prevent such ruptures, the liquid level in the discharge tank must be strictly controlled, and it is forbidden to allow the tank to become empty. Additionally, it is necessary to prevent metal objects from entering the coal slurry. Any blockage in the diaphragm chamber should be addressed promptly. Proper exhaust handling should be carried out in a timely manner, and the machine should be stopped promptly when the horizontal bar is not in use.
