How to Solve Low Pressure in Water Sprinkler Trucks?

[LeEleanor]

The most likely cause of low pressure in water sprinkler trucks is a clogged filter screen. Below are the possible causes and solutions: 1. Pump seal gaps: If there are gaps in the pump seal, air can enter the pump, leading to insufficient pressure in the sprinkler truck's water pump. In this case, carefully inspect the working pump for any gaps, water leaks due to poor sealing, air leaks in the pipeline, or burnt mechanical seals, as these issues can all result in poor sealing. 2. Clogged filter screen: Blockages in the filter screens at various levels or in the impeller flow channels of the sprinkler truck's water pump can also cause insufficient pressure. It is essential to promptly disassemble and clean the clogged filter screen in the sprinkler truck's pipeline. Due to varying water sources or inadequate protection at the suction inlet, such as being too close to the bottom, the water drawn by the sprinkler truck's pump may contain excessive impurities, leading to clogging by debris like aquatic plants, sand, stones, plastic bags, or branches. In such cases, remove the filter screen inside the filter tee, clean it thoroughly, and ensure smooth operation to restore normal functionality.
