DVMCJA Large Circulation Vacuum Intelligent Grouting Machine

The DVMCJA intelligent grouting machine consists of high-speed mixing, low-speed mixing, grouting, and computer control components. After materials are placed into the high-speed mixing cylinder to complete feeding, the system automatically starts mixing. After mixing for a certain period, the materials are automatically transferred to the low-speed cylinder for storage. Once the grouting pipes are connected, automatic grouting is initiated by clicking the corresponding button. Precision sensors are installed at both the inlet and outlet of the pipeline to monitor pressure in real time, and the data is fed back to the main system for analysis and judgment. When the system detects grout returning from the outlet, it indicates that the duct is filled with cement slurry, and the system automatically closes the return valve. The grouting machine's actions are controlled to regulate pressure and stabilize time, ensuring the grouting process is completed under critical constraints, resulting in full and compact grouting.

     Usage Precautions 1. Before starting, check that the power supply and motor rotation direction are correct. Phase loss or reverse operation is strictly prohibited. If the motor is replaced, the rotation direction of each motor must be verified. 2. Do not press the feeding cylinder during material addition, as this may lead to inaccurate measurements. 3. Strictly follow the sequence of automatic water addition → cement addition → additive addition. Deviation may affect mixing results. 4. Start high-speed mixing immediately after adding materials to prevent the mixture from setting. 5. Do not exit the grouting interface or adjust other parameters or control settings during grouting. 6. Parameter setting and calling should not be performed under the same serial number to avoid overwriting previous grouting records. 7. During grouting pause, move the slurry relief lever to the relief position. To prevent cement slurry from setting in the grouting machine, the system will automatically restart within 8 minutes. Blocking operations are strictly prohibited during grouting. 8. After grouting is completed, perform 2-3 automatic cleaning cycles.

    Our company's intelligent grouting equipment is specifically designed for highway and railway beam fabrication yards. The entire machine complies with the new highway bridge regulations and the railway standard TB/T 3192-2008, "Technical Conditions for Grouting of Post-Tensioned Prestressed Concrete Beam Ducts in Railways." The equipment mainly consists of three parts: automatic batching and mixing, vacuum pump, and grouting machine. Key technical parameters are as follows: 1. Automatic batching and mixing section: Automatic feeding, automatic weighing, automatic pressure maintenance, LCD display. Mixing speed is 1020 RPM (adjustable per customer requirements), blade linear speed is 14 m/s, weighing accuracy is within ±0.4%, significantly better than the required ±1%. It records each mixing operation and allows retrieval of historical data (this function can be disabled). The counting unit is accurate to two decimal places. The equipment includes two preset working programs, standard and simple, which users can adjust. The default setting is: automatically add 90% (or 80%) water first, then the high-speed mixing cylinder operates automatically, sequentially adding grouting agent and cement, followed by 2 minutes of mixing. The remaining 10% (or 20%) water is then added, and mixing continues for another 2 minutes before discharging into the storage cylinder with mixing function. In addition to automatic functions, manual operation is available for all or individual procedures. The mixing capacity is 700kg, sufficient for various grouting machines. 2. Vacuum pump section: Vacuum degree can reach -0.097 to -0.1, better than the required -0.092. 3. Grouting machine section: Continuous operation ensures stable pressure without fluctuations, and pumped slurry is free of bubbles. Theoretical capacity is 4.5 m³/h. It features both electronically controlled automatic and manual pressure maintenance functions. When using the DYL90 adjustable grouting pump, pressure can be infinitely adjusted and maintained within a customizable range. The pressure gauge is stable without needle fluctuation. The total range is 1.6 MPa, with a minimum division less than 0.1 MPa. The actual grouting pressure falls within 25% to 75% of the gauge range, ensuring precise measurement. Our company is a nationally recognized manufacturer of intelligent grouting equipment, adopting a low-profit marketing strategy to benefit users. According to statistics from late 2010, our automated grouting equipment holds a market share of over 65% domestically. We are highly regarded for our mature production technology, comprehensive after-sales service, and reliable product quality. I. Introduction to the Grouting Machine The CJA intelligent grouting machine uses computer control for the entire slurry preparation and grouting process. It employs a circulation method to expel air and impurities from the pipeline, eliminating the need for manual pump operation and pressure compensation. The circulating intelligent grouting technology ensures precise water-cement ratio control, automatic pressure adjustment, accurate stabilization time, automatic data recording, and continuous circulation to remove air, guaranteeing full and compact grouting. II. Working Principle of the Intelligent Grouting Machine The working principle is illustrated in Figure 1. The CJA intelligent grouting machine comprises high-speed mixing, low-speed mixing, grouting, and computer control components. After materials are loaded into the high-speed mixing cylinder, the system automatically mixes them. After a set time, the mixture is transferred to the low-speed cylinder for storage. Once grouting pipes are connected, automatic grouting is initiated. Precision sensors at the pipeline inlet and outlet monitor pressure in real time and relay data to the main system for analysis. When return grout is detected, indicating the duct is filled, the system automatically closes the return valve. The grouting machine's actions are controlled to manage pressure and stabilization time, ensuring the grouting process is thorough and dense. III. System Main Performance and Key Parameters 1.
