What are the precautions in the operation of the wet spray machine? The correct use of wet spraying machines, wet spraying trolleys and other equipment will help ensure the normal progress of construction and ensure the safety of construction personnel. For example, use mortar to lubricate the concrete wet spraying machine and the feeding pipe before spraying, and rinse the remaining concrete in the pipe with water after spraying, which can effectively extend the service life.

1. Check that the bolts of each part of the concrete pump should be tightened, the pipe joints should be tight and sealed, the protective device should be complete and reliable, and the tires should be wedge tight.

1. The pumped concrete should meet the pumpability requirements, and if necessary, the mixing ratio of the pumped concrete should be determined through test pumping.
The ratio of the large particle size of the coarse aggregate to the diameter of the concrete pump conveying pipe should be: when the pumping height is below 50m, it should not be greater than 1:3 for gravel, and should not be greater than 1:2.5 for pebbles; when the pumping height is 50-100m, It should be in the range of 1:3 to 1:4

my country began to explore the development of concrete pumps in the 1970s and introduced technology to manufacture concrete pumps in the 1980s, but the real domestic concrete pump manufacturing began.
After more than 20 years of development, China has become the largest concrete pump producer in China. In 2007, about 3,000 pump trucks were sold, and about 6,500 trailer pumps were sold. In the same period, the total output of foreign concrete pumps was only about 12,000 units.

The phenomenon of engine oil blackening is a cliché, but the blackening of hydraulic oil seems to have not been specifically mentioned. Today, the editor of the trailer concrete mixing pump will explain to you several reasons for the blackening of the hydraulic oil of trailer concrete mixer with pump mixing trailer pump:

In recent years, tunnel construction safety accidents have occurred frequently. In order to prevent hidden safety hazards, * is gradually improving tunnel construction requirements and widely adopting new construction machinery and equipment. Today, the editor of Saintyol DAWIN Machinery explains the importance of using truck mounted robot wet concrete spraying machine.

The fine stone concrete pump is a special type of concrete pump. This concrete pump is widely used in floor heating projects and floor construction, so it is welcomed by the majority of construction parties. So on the construction site, what are the pumping requirements of the fine stone concrete pump? Now let’s take a closer look.

The cutting ring of the concrete pump is originally a vulnerable part, which is used to make it repeatedly wear and tear during the working process. Under normal circumstances, the wear rate of the cutting ring can only be reduced by improving the pumpability of the concrete. The cutting ring can be reduced by checking and tightening the nuts to ensure that the gap between the cutting ring and the glasses plate is about 2 to 4 mm. Accidental damage.

More and more customers will encounter a lot of problems in the process of using the wet spray machine. Have some questions about the maintenance of the wet spray machine? Below, Saintyol DAWIN Machinery will answer your questions one by one!

Check the pressure of the main pump system of the concrete delivery pump (during pumping operation). If it does not reach the specified value, check the overflow valve and the main oil pump. For closed systems, under normal circumstances, the concrete pump motor starts and the charge pump works, and the pressure display should be around 2.5MPa. If the pressure is insufficient, adjust the charge pump safety valve and check the wear of the charge pump.

How can concrete pumps, wet spraying machines and other equipment reduce pump blockage? How can we prevent the concrete pump from being blocked? Saintyol DAWIN Machinery believes that these problems are focused on prevention, and that the solution to the problem is advanced to the product design itself, which can greatly reduce the cost of use. For example, we know that the higher the outlet pressure, the less likely it is to block the pipe. At the beginning of the pipe blockage,
