Description

Technical Field

[0001] This utility model belongs to the field of high-temperature oil pump technology, specifically relating to a mechanical seal assembly for high-temperature oil pumps. Background Technology

[0002] The high-temperature oil pump consists of components such as the pump body, pump cover, inner and outer rotors, pump shaft, and shaft end seal. The main drive is a set of meshing rotors. The shaft end seal adopts a high-temperature resistant reflux type combined seal and uses a water tank cooling method to control the shaft seal temperature. It is a positive displacement pump, which relies on the change in working volume caused by the meshing of the main and driven gears to transport the melt. The working volume is composed of the pump body, the gear teeth, and the bearing with side plate function. The pump and the motor are connected by a three-jaw flexible coupling to form an oil pump unit, which has the characteristics of low noise, reliable sealing, long service life, and safe and reliable use.

[0003] Existing high-temperature oil pumps still have some shortcomings. When using the oil pump, the oil inlet and the transport pipe need to be connected. Most of the connections have poor sealing, and oil leakage will occur after a long period of use, which is inconvenient. To address this, we propose a mechanical seal assembly for high-temperature oil pumps. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical seal assembly for a high-temperature oil pump, comprising a base and a support plate. One end of the base is provided with a support plate, which is fixedly connected to the base. One end of the support plate is provided with a housing, which is fixed to the support plate by welding. One side of the housing is provided with an oil inlet, and one end of the oil inlet is provided with an oil pipe. A sealing groove is embedded in one end of the oil inlet, and a first sealing gasket is provided inside the sealing groove. The first sealing gasket is made of an elastic material. One end of the oil pipe is provided with an insert plate, which is fixed to the sealing groove by interlocking. One end of the insert plate is provided with a second sealing gasket.

[0006] Preferably, the oil pipe is provided with a sealing plate inside, and the oil inlet is provided with a third sealing gasket inside, and the third sealing gasket is fixedly connected to the oil inlet.

[0007] Preferably, one end of the oil pipe is provided with a first flange, and one end of the oil inlet is provided with a second flange, the second flange and the first flange being fixed together by bolts.

[0008] Preferably, a motor is provided at one end of the base, and the motor and the base are fixed together by screws.

[0009] Preferably, the output end of the motor is provided with a rotating shaft, the rotating shaft extends into the interior of the housing, and the top of the housing is provided with an oil outlet.

[0010] Preferably, a mounting member is provided on one side of the base, and the surface of the mounting member is embedded with mounting holes, and the mounting member is provided with four holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The sealing groove, first sealing gasket, insert plate and second sealing gasket effectively improve the sealing performance between the oil inlet and the oil pipe. When installing the oil pipe, the insert plate will be inserted into the inside of the sealing groove, and the two sealing gaskets will squeeze each other, which will enhance the sealing effect.

[0013] 2. With the provided sealing plate and third sealing gasket, as the insert plate is inserted into the sealing groove, the sealing plate will press against the surface of the third sealing gasket, further improving the sealing between the oil pipe and the oil inlet. Then, the bolts are passed through the two flanges and fixed with nuts, thus completing the fixing of the two flanges and fixing the oil pipe and the oil inlet. Attached Figure Description
