Abstract
The utility model discloses a hot oil pump with graphite packing rings, which solves the problem of oil leakage in the position of a pump shaft of the hot oil pump. The hot oil pump comprises a base and a pump body, wherein the pump body is arranged on the base; a pump cover is mounted on one closed side of an oil inlet of the pump body; an impeller is arranged in the axial direction of the oil inlet in the pump body; the impeller is connected with the pump shaft by a key groove; the pump shaft passes through the pump cover and a bearing seat fixedly connected onto the pump cover in sequence, and is connected with a motor by a shaft coupler; the motor is fixedly mounted on the base; and at least one graphite packing ring is arranged between the pump shaft and the pump cover. According to the hot oil pump with graphite packing rings, the traditional hot oil pump sealing mode is changed, and the graphite packing rings are adopted for sealing treatment; the graphite packing rings have the characteristics of high temperature resistance, good thermal state adaptability and strong corrosion resistance, so that the sealing performance is greatly improved, the problem of oil leakage of the hot oil pump is solved, the use efficiency of the hot oil pump is improved and the service life of the hot oil pump is prolonged.
Description
Technical field
The utility model relates to the hot oil pump technical field, especially a kind of hot oil pump that can solve hot oil pump in pump shaft place leakage of oil problem.
Background technique
At present; In known hot oil pump technical field; The working environment of hot oil pump is often relatively more abominable, cause the air-proof condition of pump shaft harsh, and known hot oil pump often adopts simple oil sealing or mechanical seal on pump shaft; The effect of sealing is unsatisfactory, so tend to make hot oil pump that the accident of leakage of oil takes place in the pump shaft junction.
The model utility content
The technical problem that the utility model will solve is: a kind of hot oil pump that can solve hot oil pump in pump shaft place leakage of oil problem is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of hot oil pump with graphite packing circle; Comprise base, be arranged on the pump housing on the base; Pump cover is installed on pump housing filler opening and seals a side, in the pump housing, axially is provided with impeller along filler opening, and impeller is connected with pump shaft through keyway; Pump shaft passes pump cover successively, is fixedly connected on the bearing support on the pump cover; And pump shaft is connected with motor through coupling, and motor is fixedly installed on the base, between pump shaft and pump cover, is provided with at least one graphite packing circle.
Further, in order to fully take into account the requirement that limits graphite packing circle position, between described pump shaft and pump cover, be provided with circlip for hole near pump housing inner chamber one side.
Further, in order to fully take into account the requirement of the flexible location between graphite packing circle and the circlip for hole, between described graphite packing circle and circlip for hole, be provided with lining ring.
The beneficial effect of the utility model is: the utility model is through changing traditional hot oil pump sealing means; Adopt the graphite packing circle to do encapsulation process, the graphite packing circle is high temperature resistant, has good hot adaptability; Corrosion resistance is strong; Make that the performance of sealing is significantly improved, solved hot oil pump leakage of oil problem, improved the utilization efficiency and the life-span of hot oil pump.
