To the High-Pressure Cleaning Truck Operators
1. On the water requirements
When high-pressure cleaning truck using rivers, ponds as water sources, note the end of all the suction pipe submerged. Stones or more to avoid inhalation of the sediment, floating debris, suction tube ends are generally equipped with filtration devices, water filtration devices are forbidden to be removed. If the water shallow, you need to advance some of the water at the deepened to ensure that does not contain debris and not into the air.
2. Add water
Before each suction centrifugal pump must be added to the water pump a certain amount of water, after adding additional outlets must be closed. Self-priming pump for the first time use, the need to add water and, thereafter, no need for water.
3. Inlet pipe will need to vacuum
When the inlet water systems must maintain a certain degree of vacuum to suction the water box. Into the plumbing system must be sealed and reliable, hoses can not be broken, the tube can not have cracks or air leaks will produce, will result in the case of no water absorption.
4. Stop hanging files
High-pressure water cleaning vehicles either in front or in the job before taking power devices linked files must be carried out in the parking.
5. Winter drainage
Before winter, should the water pump and vent pipes to prevent cracking. Winter in northern China is no longer the general construction, so the construction is completed, you immediately the water pump and drain pipes to prevent future trouble.
6. Regular sewage
Vehicle storage tanks with high pressure cleaning sewage pipes, the pipes for the water tank of the lowest import. After a period of use, should be regularly open the outfall switch, the accumulation of debris inside the tank removed, until the water clear up.
