How does the low temperature system sand machine carry on the maintenance in winter?

Sand machine in addition to normal maintenance, in winter low temperature, in order to ensure the normal work of the sand machine, need to pay attention to correct maintenance, equipment lubrication needs to be done in place. The volume of the Sand Machine and the capacity of the oil tank are not big, when the oil temperature is high, which requires good thermal stability and oxidation resistance of lubricating oil, but also have a good rust, corrosion resistance. Anti-emulsifying properties. In order to ensure the normal work of the sand machine. Due to the dry climate in winter, the sand machine requires the use of good fire-resistant lubricants, the requirements of good adaptability of lubricants to the seals, so as to avoid damage to the seals.

1. In winter, when the sand-making machine is ready to start up, the corresponding operators and managers should study the relevant knowledge and problems of winter construction in advance, and do a good job of winter construction materials. Spare parts maintenance and other plans to ensure the smooth winter construction, every day before the operation of the machine, to check the machine, start the switch first enough to warm up.

2. Sand machine are open-air work, in the temperature below zero, the mechanical reinforcement. Air compressor ground pump. Tower Crane Sand machine gearbox oil: oil should be replaced by -25 # above the oil to ensure normal operation, because of the temperature difference between day and night, the requirements of oil viscosity with the temperature change to small, both to avoid high temperature, oil viscosity becomes too low to form a lubricant film, not to play the role of lubrication, but also to avoid low temperature viscosity is too high, so difficult to start operation.

3. To improve the balance accuracy of the rotor, the sand machine rotor mass high speed. The casting deviation of the rotor body and the mass deviation caused by the installation of the plate hammer will cause the rotor to produce an unbalanced centrifugal force when it rotates.

4. The ground pump should follow the short circuit when the pipeline is laid. The principle of tight elbow less joint, ground pump. The pump pipe connection of the distributor should not leak, in the lower temperature or cold, the pump pipe to carry out insulation, wrapped with insulation materials.

5. The stone washing machine is equipped with special personnel to eliminate the stagnant water on site. Ice deposits. Sundries and other work, to protect the stone washing machine work site no water and ice.

6. Under the condition of low temperature in winter, the tension of conveyor belt will be affected, and there may be cracks, can be avoided because the tension caused by different belt rupture affected the production line for a series of problems, if there is a problem, should be replaced in a timely manner. Sand machine is a common equipment in mining machinery, a large sand factory. Stone plant, such as these equipment are open-air production, so when the arrival of cold winter,-must pay more attention to the daily maintenance and regular maintenance of sand machine.
