How to maintain concrete sprayer? In order to extend the service life of the spraying machine, reduce the wear and tear of the wearing parts of the spraying machine, and reduce the construction cost, we need to understand the maintenance methods of some concrete spraying machines.
1. The rubber board of the spraying machine is the key component of the spraying machine, and we must pay great attention to their maintenance so as to ensure that no malfunction occurs during the work. The compaction force exerted by the rotor clamping system on the rubber plate is not uniform across the entire plate surface, and is greatest between the discharge port and the remaining gas port, and the maximum pressure point constantly drifts back and forth with the rotation of the rotor. Rubber plates do not allow excessive stress due to over-clamping, which can cause excessive wear due to frictional heat generation. The heat-resistance limit of the rubber plate is 110°C, and it is normal that the rubber plate does not exceed 80°C in use. This difference in pressure can be resolved by a floating single point clamping system, which makes the joint surface extremely small when the machine is in operation. Therefore, in the use of the machine, the correct clamping has an important influence on the wear cost. If it is not clamped properly, the pressure gas will escape at the interface between the two plates and carry out fine particles, creating dust next to the machine. The outburst of this fine sand will erode the sealing plate and cause it to fail in a short time.
2. The sprayer's steel liner must be inspected once a week. If the depth of deep scratches exceeds 1mm, it should be reground. The edge of the circular hole of the steel liner should be inspected frequently. It must maintain a sharp edge. If the edges are chamfered, fine particles can easily penetrate into the bonding surface, increasing wear, if a new sealing plate is replaced, and the old steel backing material holes with beveled edges, the service life of the new sealing plate It will be significantly shortened. Timely repair of steel liners to remove worn parts can save a lot of trouble and save money.
3, anti-adhesive material cavity and cyclone with anti-sticking function, generally do not bond at work. However, after the end of each shift, the rotor should be opened to check and clean the cyclone.
4, should always pay attention to reducer maintenance and maintenance:
1) The oil for the reducer is No. 50 industrial gear oil (SY1172-77S) or No. 30 mechanical oil.
2) The temperature rise during operation of the reducer must not exceed 40°C.
3) After the work is done in each shift, clean up the mixes and Other impurities on the reducer surface.
4) Always check the oil level and fill it in time if there is not enough lubricant.
5) Replace lubricant after 250 hours (about 3 months).
6) Check whether the reducer has oil leakage and deal with the leakage timely.
7) Each week, the bearing of the rotor square shaft should be filled with grease, that is, screw the bolt at the upper end of the square shaft, add the grease, and press down the oil with the bolt.
8) Always clean the area around the air hood on the reducer cover to ensure that the vent holes are clear.
5, often check the dial plate on the feeder, fork, etc. are deformed, open welding. Constantly adjust the gap between the plate and the hopper base (4 mm) to prevent the plate from rubbing the base directly.
