Abstract

The invention relates to a pump body packing box of a coal cutter. The pump body packing box comprises a packing base connected to a pump shaft and packing and is characterized in that a packing ring is connected in the packing base, the end of the packing base is connected with a packing gland, an I-type ring groove is formed in the packing ring, and the packing is arranged between the packing ring and the packing gland. Compared with a traditional pump body packing box, the pump body packing box of the coal cutter has the advantages of being simple in structure, convenient to load and unload, good in working effect and small in size.

Description

Technical field: [0001] The invention relates to the field of coal mining equipment, in particular to a pump body sealing device of a coal shearer. Background technique: [0002] In coal mining equipment, water pumps are essential equipment, in which a sealing structure is required between the high-speed rotating pump shaft and the fixed pump body. This sealing mechanism is called a stuffing box, and its function is to reduce the pressure during drainage. Water leakage prevents air from entering the pump on the suction side, and plays the role of water lubricating and cooling the pump shaft. The traditional sealed stuffing box has the disadvantages of complex structure and inconvenient loading and unloading. Invention content: [0003] The applicant, aiming at the above-mentioned shortcomings of the traditional sealed stuffing box of the pump body, conducts research and improvement, and provides a pump body stuffing box of a coal shearer, which has the characteristics of ...
