Slurry pump is a very commonly used equipment in a few mineral industries. In the production of a few coal preparation plants, the use of slurry pump is more limited. It can transport slurry water, recycled water, etc. The operation of slurry pump will directly affect the normal operation of all production systems. Then let the small editor of slurry pump manufacturer introduce the common problems and solutions of this equipment to you.
1、 Slurry pump fails to start
First, check the power supply environment: discuss whether the power supply is continuous; whether the switch contacts closely; whether the fuse is blown; whether the three-phase power supply is lack of equality.
2、 Slurry pump does not operate;
The measures to remove the silt can be taken.
3、 The flow of slurry pump is less than;
If the impeller or inlet and outlet water pipes are blocked, wash the impeller or pipes. If the impeller is worn and strained, it shall be replaced. In case of air leakage at the packing port, the packing shall be compacted.
4、 No water absorption of slurry pump (no sizing)
There is air in the pump body or air accumulated in the water inlet pipe, or the bottom valve is not closed tightly, the filling of the vacuum pump is tight and air leaks, and the gate valve or flap valve is not closed tightly. Breaking skills: first put the water pressure up, then fill the pump body with water, and then start the machine. At the same time, check whether the check valve is precise, whether there is any sign of air leakage in the pipeline and discussion. If air leakage is found, apply lubricating oil or blending paint on the discussion place after disassembly, and tighten the screws. Search and inspect the oil seal ring of water pump shaft, and replace it with a new one if it is worn. Water or air leaks in the pipeline. The nut may not be tightened tightly during installation.
