At the same time, the oil tank is equipped with temperature measurement and level meter and filter element alarm clogging device. When the filter element is blocked, the alarm device notifies to replace the filter element.
三、Machine layout, inspection, installation and preparation
The installation plane layout of the machine should be determined according to the production site and product process requirements. In principle, it is required that mixing, mobile grouting, wall panel molding, demoulding and maintenance turnover do not interfere with each other. It is recommended to arrange according to the installation foundation diagram.
Before installing the device, the installation and operation personnel should read the relevant documents carefully, make the installation plan, and make necessary preparations. Check the size of the foundation according to the foundation drawing. The levelness of each part of the plane should meet the requirements of the drawing. The foundation surface should be cast with cement.
Note: the position of the embedded parts and guide rails should be accurate and firm, and the foundation should meet the design requirements to achieve the allowed installation strength.
四、Production process flow
The different required ratios of raw materials are measured and then placed in the mixer for mixing. At the same time, the grouting machine is moved to the floor below the mixing to wait and store the materials. The wall panel molding machine is equipped with the mold, and the grouting machine moves to the side of the wall panel molding machine along the guide rail to grouting the wall panel molding machine, and the grouting completes the resting of the wall panel molding machine. The stripping and turning platform is moved to the other side of the molding machine, and the product is demudded. The turning platform is rotated 90 degrees and stands upright. The forklift is moved to the back of the turning platform to fork the wall panel.
1, the entire production process of the board
Clean the mold → spray release agent → Install the mold → pouring → shaping (appropriate heating) → constant temperature steaming → cooling → mold opening → mold exit → inspection → storage
2. Detailed explanation of flow chart
2.1 Cleaning mold: mainly clean the surface of cement blocks, foreign bodies, etc., so that the surface of the mold is clean without debris, the overall flatness is high, and pay attention to not leaving dead corners when cleaning.
2.2 Spray film removal agent: the amount of spray should be small and uniform, and too large film removal dose will affect the surface quality of the wall board, mainly pores. After drying, the film removal agent is easy to form dirt, and it should be regularly removed to ensure product quality.
2.3 Mold closing: after the core is installed, the mold must be closed in place, and the plate spacing must be measured one by one after the mold closing, which is a necessary means to ensure the thickness of the plate, and to ensure that the front mold is just stuck in the limit slot.
2.4 Mixing ingredients: strictly in accordance with the mixing process, the error of various materials shall not exceed 2%, the mixer should be watered and moistened before mixing, and the mixing consistency should be moderate.
2.5 Pouring: The pouring of the plate should be divided into uniform pouring, and special attention should be paid to vibration when pouring, and automatic vibration should also be set.
2.6 Shaping: After pouring, the top should be shaped. The closing must be flat and no individual protruding points are allowed. After shaping, the size error should be less than 2mm.
2.7 Constant temperature steaming: pay attention to the temperature control at 25℃/ hour, the high temperature control at 40-50℃ steaming covered with insulation, to prevent cracks, heating and constant temperature steaming for 150 minutes.
2.8 Cooling, mold opening, mold out: to open the mold after cooling, the temperature difference between the mold opening temperature and the ambient temperature of the plate should not be greater than 20℃, and the protection of the end of the wall board should be strengthened during the lifting process to prevent damage due to lifting, and measures should be taken for light defects and can be remedied to improve the quality of the product.
2.9 Inspection and warehousing: The wall panels after the mold should be vigilant, inspected and marked, and classified into the warehouse according to the quality level.

2. Check and maintain the hydraulic system regularly
2.1 The hydraulic station should often check the use of hydraulic oil, it is important to ensure that the working environment of the hydraulic station is clean, and do not enter any stolen goods into the hydraulic system. If the oil is found to be deteriorating, replace it with new oil immediately. Usually, the oil in the hydraulic station should be filtered and replaced regularly. Generally, it is filtered once every six months. Special note: New oil is not really clean oil. Because the oil drum is rarely cleaned, there may also be stolen goods on the pump used when the oil is loaded. Even the new oil is contaminated. Therefore, the oil that is required to be injected into the tank must be filtered. If conditions permit, the user can add an oil filter.
2.2 After the adjustment of the hydraulic station, in the use or stop state, any personnel shall not arbitrarily twist the handle of the relevant valve parts to ensure the normal use of the hoist.
