(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor.
Understanding the ZJ Slurry Pump
It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.
The innovation behind the ZJ slurry pump lies in its hydraulic design. It is engineered to achieve high efficiency in the transfer of slurries, reducing both energy consumption and operational costs. Available in different sizes and designs, the ZJ pump can be tailored to meet the specific demands of various applications, including dredging, tailings management, and waste handling.
