In the actual construction site, when the diesel engine concrete pump is pumping and washing, the water in the hopper is sprayed, and the cutting ring of the glasses plate should be disassembled. I think this concept is wrong. It is best to disassemble the glasses plate and the cutting ring. When there is often concrete segregation in the concrete pumping, and the glass plate and the glasses plate are found to be seriously damaged, they should be disassembled. When the concrete segregation is corrected, the hydraulic cylinder of the main hydraulic cylinder stays in a casual position, and the pressure of the main operating system is larger than 31MPA. At this time, the plastic hose at the root is still not fed, and the concrete is isolated. The difference between concrete segregation and reversing pressure is that the concrete segregation is that the hydraulic cylinder of the main hydraulic cylinder stays in a casual position and has a one-sidedness, while the reversing pressure is that the hydraulic cylinder of the main hydraulic cylinder stays in the reversing position.

The Accessories of Diesel Engine Concrete Pump: How to solve the problem of glasses plate and cutting ring?

For diesel concrete pump, the most basic method for operators to deal with concrete segregation:

1. First anti-pump, after the positive pump, so lasting 2-3 times, it should be resolved, if still can not be resolved, then can not be positive, anti-pump. Otherwise, the concrete at the separation of the pipe concrete is getting tighter and tighter, and there is no way to make underwater concrete.

2. If it is blocked in the boom, it can be vertically divided into the boom, first reverse pump, then positive pump.

3. Check the pumpability of concrete, if not very good, then pump the concrete into the hopper, then put the material in the hopper clean and tidy, re-feed, and then pump concrete.

4. Reverse the pump first, disassemble the pipeline at the location of the concrete separation, and eliminate the concrete isolated from the concrete. (Asphalt concrete at the bottom of the S tube and at the bottom of the No. 1 elbow will also cause concrete to segregate).

Difficulties in the installation of the glasses plate cutting ring of diesel concrete pump:

1. When the glasses plate is installed, the installation surface of the hopper is cleaned and cleaned, and it is clear that the relative butt joint has no protrusions, which is not a transitional fit, which may cause the eye plate to deform itself, and may not eliminate the deformation of the eyeglass plate itself.

2. When not disassembling the S pipe, be sure to ensure that there is no concrete or sediment at the installation position of the rubber damper. Otherwise, the glasses plate will be found to be abnormally damaged, and even the glasses plate will fall into the hopper.

3. After the eye plate cutting ring is installed, you should not find a gap. Otherwise, the eye plate cutting ring will be found to be abnormally damaged, and even the glasses plate will fall into the hopper. A lot of textbook content is required to have a gap of 0.07-0.1MM is wrong, because the rubber shock absorber as much as possible to support the board, the glasses plate and the cutting ring as close as possible, the previous damage will be reduced.
