How to repair concrete sprayer? The Henan Yanli Shotcreting Machinery Factory has a look at the maintenance method of the concrete shotcreting machine and hopes to help the use of the shotcreting machine.
1. The rubber sheet and steel liner of the spraying machine are the key components of the spraying machine. Be sure to pay attention to their maintenance so as to ensure that no malfunction occurs during the work.
The pressing force exerted on the rubber plate by the pressing mechanism is not evenly distributed across the plate surface, and is greatest between the discharge port and the remaining gas port, and the maximum pressure point continuously drifts back and forth with the rotation of the rotor. Such pressure The difference can be solved by the clamping mechanism, so that when the spraying machine is running, the air leakage at the joint surface is extremely slight. The correct clamping of the sprayer during use has an important influence on the wear and tear costs. If it is not clamped properly, the air pressure will escape at the interface between the two plates and carry out fine particles, which will generate dust next to the machine. This explosion of fine sand will erode the sealing plate and cause it to fail in a short time. The rubber plate is not allowed to cause excessive wear due to excessive clamping, otherwise it will be excessively worn due to friction and heat. The heat-resistance limit of the rubber plate is 1100C, and it is normal that the rubber plate does not exceed 800C in use. Each class should clean the rubber plate and check for wear. If the rubber plate has been worn to the extent that the steel inserts are flush with the surface of the rubber or there are gas leaks in the excess air holes and feed holes, the rubber plate must be replaced. Because at this time, the steel lining plate will directly contact the steel ribs so that the sealing plate can not be fully pre-tightened to obtain an effective seal, thereby losing its airtightness.
The steel liner must be inspected once a week. If deep scratches (depth greater than 1mm) occur, it should be reground. The edge of the round hole of the steel liner should be inspected frequently. It must maintain a sharp edge. If the edge is beveled, the fine particles can easily penetrate into the joint surface and increase the wear. If a new rubber plate is replaced and the old steel backing material holes have beveled edges, the service life of the new rubber plate will be significantly shortened. Timely repair of steel liners to remove worn parts can save a lot of trouble and save money.
2, anti-adhesive material cavity and discharge elbow with anti-sticking function, generally do not stick in the work, but after the end of each shift should open the rotor, check the elbow to clean up.
3, should always pay attention to the maintenance and maintenance of reducer:
A. After the work of each shift, clean up the foreign materials such as mixing materials and other materials adhering to the outer surface of the reducer.
B. Observe the oil standard frequently and fill it in time when the lubricant is insufficient. Lubricant is No. 50 industrial gear oil or No. 46 mechanical oil;
C. Replace lubricant after 250 hours (about three months) of accumulative work;
D. The rotor shaft bearing grease should be promptly filled (the top of the square shaft is filled with oil).
