Three water wash methods of S pipe valve concrete pump
Water washing of S-type valve concrete pump is a way to maintain the machine. It is very important to prolong its service life. Therefore, the water washing of S-type valve concrete pump has been widely used in engineering projects. The water washing of S-type valve concrete pump is divided into three kinds according to the difference of water source.
一：Machine self-priming water replenishment
The method of machine self-priming water replenishment of S-type valve concrete pump is to directly open the drain pipe on the shell of the pump to empty the water and gravel inside the S-type valve, and then pour clean water into the S-type valve concrete pump from the water inlet at the bottom of the pump, and then operate the S-type valve concrete pump. When the S-shaped valve opens and closes, the water can be circulated out of the pump more easily. Through this method, the internal water of the pump can be replaced several times for cleaning. This method of S-type valve concrete pump self-filling water is mainly used for special occasions and small flows, and can generally only clean the type and small sandstone mixed in the type.
二：External water pressurization
The method of external water pressurization of S-type valve concrete pump is to pressurize the water in the chamber by external water pressure, so that the water and gravel in the chamber can be rapidly discharged and replaced. The external water pressure is higher and the water in the chamber can be discharged more quickly. Generally, the better method is to use water gun or high-power industrial pump to pressurize the water in the chamber, or to use a water pipe to directly connect to a water tower, so that the chamber can be flooded and ventilated several times within a short time. This method can be used to clear away a large part of the remaining impurities on the surface of the S-type valve, bits and pieces of stone, etc., which can be used for most occasions.
三：External water injection
The external water injection method of S-type valve concrete pump is to use a high pressure industrial pump to inject a large amount of clean water into the water tank at a time, so that the dirt and stones in the water tank can be taken away quickly. This method can effectively clean the surface of the S-type valve, but the cost is the highest. Generally, it is only used for occasions with large sandstone, but for most occasions, only water replenishment or external water pressurization methods are available.
In short, in the maintenance of S-type valve concrete pump, it is necessary to choose the right water washing method according to the gap log size and water quality, and pay attention to the safety problem in the group operation.
