The pipeline cleaning vehicle is an important tool to help clean the sewage pipelines. During the cleaning process, a large amount of water is needed. Since the pipeline cleaning vehicle is used to clean the dirt, most of the time it will not use the drinking water. In this case, the use cost is too high. Instead, it will use other water sources, such as rivers and ponds. When using these water sources, pipeline cleaning vehicles have relevant requirements for the use of vehicles. Most of the pipeline cleaning vehicles use the water in ponds and canals during the cleaning process. The water sources in these areas are relatively clean and the amount of water is relatively large, which can support the pumping of pipeline cleaning vehicles. However, when pumping water, make sure that the suction pipe end is completely in the water, so as to avoid adsorbing sludge, dirt, sediment, stones and other debris from the water. This is equivalent to using dirty water to clean the pipeline. The more dirty it is cleaned. Before the pipeline cleaning vehicle absorbs water, it must be ensured that the inlet pipe is in a vacuum state before it can ensure that water can be sucked into the tank. The sealing system of the water inlet pipe system should be sufficient, and the hose and the rigid pipe must not be damaged, so that no leakage will occur and no suction will occur. No matter whether it is before or after water absorption, the pipeline cleaning vehicle needs to be stopped to ensure its normal use. In the winter, due to the cold in the north, most of the pipeline cleaning vehicles are in a suspended state. At this time, the water in the vacuum pumps and pipes should be drained to avoid freezing and damage. The difference between a pipeline cleaning truck and other special vehicles is that it has a sewage pipe. During the process of using the sewage pipe, there will be related impurities. It is necessary to periodically remove these debris, so that the water in the boiler can be cleared. Pipe cleaning car on water What are the requirements?

There are a few plaster sprayers that have a peristaltic pump (a tube squeezed by rollers) which also requires compressed air to produce a spray. These types of plaster sprayer can also spray textured coatings with particle sizes up to about 3mm diameter, providing that they are not solvent based.
Piston pump
Newer types of plaster sprayer have a piston pump, which has sufficient pressure to spray smooth (untextured) plaster without compressed air. Full airless pumps are sometimes used to spray smooth plaster, although they are not ideal as the flow rate is too low for volume projects; however, they can be used to spray solvent-based plasters.
Air operated piston type supply pumps can put out as much as 27 gpm. Like the Graco Bulldog 10:1 at about 9 gpm and the Lincoln Pile driver 5:1 at about 27 gpm. These flow-rates are calculated at a maximum of 120 cfm air supply. Material supply hoses are medium pressure at about 600 psi. These pumps are material supply pumps only and additional air is required at the Spray Gun to propel the material to the surface. These guns are usually an internal mixture type guns where the material and air exits the gun together.
