Can the pump filter be blocked be determined from those phenomena? 1. The pump outlet pressure is low, with significant fluctuations ； 2. The opening of the control valve at the pump outlet increases significantly, causing the liquid level in the equipment connected to the pump to rise slowly, while the liquid level in the equipment downstream of the pump decreases ； 3. Motor current decreases.
1. The pump outlet pressure is low, with significant fluctuations； 2. The opening degree of the control valve at the pump outlet increases significantly, causing the liquid level in the equipment connected to the pump to rise slowly, while the liquid level in the equipment downstream of the pump decreases ； 3. Motor current decreases.
⑴The outlet pressure of the pump decreases, with significant fluctuations. ⑵The opening of the pump outlet control valve increased significantly, causing the liquid level in the towers and tanks feeding into the pump to rise slowly. ⑶The motor current decreases.
1. Low pressure at the pump outlet, with significant fluctuations; 2. The opening degree of the control valve at the pump outlet is greatly increased; 3. The liquid level in the equipment connected to the pump rises slowly, while the liquid level in the equipment downstream of the pump decreases; 4. The motor current decreases
