How to repair and maintenance What are the safety operation procedures of Repulsion Machine? Henan Hao Li sprayer manufacturers detail the maintenance, maintenance and safe operation flow of Hao Li.
1. Maintenance and Maintenance of Rubber Sheet and Steel Liner of Shotcreting Machine 1. Before the injection of each class, the pressing force applied on the rubber sheet of the spraying machine should be inspected, and the pressing force is too small, which will cause the pressure air flow from the joint surface. overflow. The fine particles carried by it enter the sealing surface, aggravating the wear of the rubber plate and the steel liner. Excessive tight pressure can lead to increased wear of the rubber plate and increased power consumption of the motor.
2. After the class is completed, the surface of the rubber sheet and the steel lining board must be cleaned and the wear condition of the rubber sheet and the steel lining board must be inspected while cleaning the spraying machine.
(1) The degree of abrasion of the rubber sheet is measured by whether or not an effective seal can be achieved. If there is gas in the high and low pressure range can not be isolated and the sealing surface has a deep groove, the rubber plate must be replaced.
(2) The surface of the steel liner must not have deep scratches. If the scratch depth exceeds 1 mm, it needs to be reground. The edges of the steel liner feed opening must be sharp edges. If the edges are chamfered, fine particles in the work will seep into the bonding surface between the rubber plate and the steel backing plate, resulting in increased wear of the rubber plate and shortening its service life. The steel backing plate should be repaired in time.
Second, the spraying machine safety operation process 1, gunning maneuver, you must first join the compressed air, the direction of rotation of the motor should be consistent with the direction of the arrow shown in the body, and finally to feed. Stop feeding before shutting down, and then stop sending compressed air.
2. The sprayer should be kept clean and dry. When working with the so-called dry material, the sprayer should meet the requirements of the sprayer. Do not use a cement or a whole cement to avoid blocking and affect the work process.
3, spray machine operators should maintain close contact with the jet operators, air supply, feeding, shutdown, stoppage, and clogging should be coordinated with each other.
4. When the spray operation is stopped, the nozzle cannot be aimed at someone's place to avoid accidents.
5. In the shotcrete operation, if the stop time exceeds one hour, all the dry mix (without water) in the compartment and in the feed pipe must be sprayed.
6. If the spray pipe is clogged, tap the outer wall with a wooden stick. If the tap is invalid, the hose can be disassembled and blown with compressed air.
7. When the sprayer is stopped, the feeding should be stopped first, then the motor is turned off and the compressed air is stopped.
8. After the operation, all the dry mixture in the chamber and the spray pipe should be sprayed, and the nozzle should be removed and cleaned to remove the concrete and debris adhering to the inside and outside of the fuselage. At the same time, the feeding tube should be cleaned and the seal should be in a relaxed state.
