Hot oil pump provided with graphite padding rings

Abstract

The invention relates to a hot oil pump provided with graphite padding rings. The hot oil pump can solve the problem of oil leakage at a pump shaft. The hot oil pump comprises a base and a pump body arranged on the base. A pump cover is arranged on a closed side of an oil inlet of the pump body. An impeller is arranged in the pump body along the axial direction of the oil inlet and is connected with the pump shaft through a key groove. The pump shaft sequentially passes through the pump cover and a bearing seat fixedly connected on the pump cover and is connected with a motor through the coupler. The motor is fixedly arranged on the base. At least one graphite padding ring is arranged between the pump shaft and the pump cover. According to the hot oil pump, a traditional hot oil pump sealing method is changed, the graphite padding rings are adopted for sealing treatment, and the graphite padding rings resist high temperature, are good in heat state adaptability and strong in corrosion resistance capacity so as to greatly improve sealing performance, and therefore the problem that the hot oil pump leaks oil is solved, utilization efficiency of the hot oil pump is improved, and service life of the hot oil pump is prolonged.

Description

Technical field [0001] The invention relates to the technical field of hot oil pumps, in particular to a hot oil pump capable of solving the problem of oil leakage of the hot oil pump at the pump shaft. Background technique [0002] At present, in the well-known technical field of hot oil pumps, the working environment of hot oil pumps is often harsh, resulting in harsh sealing conditions of the pump shaft. However, the known hot oil pumps often use simple oil seals or mechanical seals on the pump shafts, and the sealing effect is not good. Ideal, so the hot oil pump will often cause oil leakage accidents at the joint of the pump shaft. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a hot oil pump which can solve the problem of oil leakage of the hot oil pump at the pump shaft. [0004] The technical solution adopted by the present invention to solve its technical problems is: a hot oil pump with a graphite packing ring i...

Problems solved by technology

[0002] At present, in the known thermal oil pump technology field, the working environment of the thermal oil pump is often relatively harsh, resulting in harsh sealing conditions for the pump shaft. However, the known thermal oil pumps often use simple oil seals or mechanical seals on the pump shaft, and the sealing effect is not good. Ideal, so it often causes oil leakage accidents at the joint of the pump shaft in the hot oil pump
