Spraying machinery and equipment layout shall be reasonably determined in accordance with the general layout of the construction of the transmission radius of raw materials and mortar should be shortened, reducing the number of mobile devices.
Mortar mixer and the installation of flat-panel shaker should be strong, the operation should be convenient for feeding the material should be smooth.
3, installation of mortar joint machine venues should be a solid formation, and should be placed on the concrete floor. Wheels should be wedged firmly placed should be smooth.
4, the mortar joint machine should be installed in the mortar mixer and shaker of the lower part of the feed inlet should be placed in the bottom of the mortar mixer discharge port dovetail with each other. The discharge height should be 350-400mm
5, the spray should be used to the dual valve control switch, installed after debugging, open and close should be easily accessible and remote control performance should be reliable.
Spray equipment should have a hand operation and management, clear responsibilities, should be close coordination with the spraying operations personnel to meet the requirements of the construction.
7, the formal work of spraying equipment should be carried out empty load commissioning consecutive empty running time of 5min, and should check the motor rotation direction, working systems and safety devices, the operation should be normal and reliable.
8, when the spraying equipment should be frequently observed in the pressure of the pump changes, when the gauge pressure exceed the maximum pressure value, should immediately open reflux unloading valve pressure relief and stop checking. Mortar machine Common Faults and exclusion method, see Appendix B
9, according to the height of the plastering project the amount of cooperation in industry, can transform the pumping speed, select the appropriate mortar throughput. When the mortar conveying capacity can be used to tell block; can choose low gear for high pumping pressures or difficult to transport mortar; under normal circumstances, the choice of medium-speed block.
10, when spraying different materials or different consistency of the mortar should be adjusted to the air nozzle position, dual valve open to co-gas flow, so that the mortar spray evenly with the primary bond firm and reduce the rebound landed gray.
