Mechanical sealing mechanism for water pump

Abstract

The invention relates to the technical field of mechanical seals, in particular to a mechanical seal mechanism for water pumps, comprising a connecting seat and a lower shock-absorbing sealing seat, the outer surface of the upper end of the connecting seat is provided with connecting screws, and the lower end of the connecting seat is fixedly installed with an upper The sealing seat, the outer surface of the upper end of the upper sealing seat is fixedly equipped with a lifting ring, and the outer surface of the lower end of the upper sealing seat is provided with an auxiliary supporting column and a sealing chamber, and the sealing chamber is arranged on one side of the auxiliary supporting column. A limit hole is arranged on the outer surface of the front end of the sealed chamber. A mechanical seal mechanism for a water pump according to the present invention is provided with a lifting ring, an auxiliary support column, a No. 1 auxiliary seal ring and a lower shock-absorbing seal seat, which can facilitate the user to transport the seal mechanism, and at the same time make the structure of the seal mechanism more compact. It is stable, and at the same time can make the sealing performance of the mechanism better, and can also make the sealing mechanism better in shock resistance, is suitable for different working conditions, and brings better use prospects.

Description

technical field [0001] The invention relates to the technical field of mechanical seals, in particular to a mechanical seal mechanism for water pumps. Background technique [0002] Pump mechanical seal refers to a device that is installed and operated in pump equipment to play a dynamic sealing role. It prevents the fluid medium in the pump volute from flowing out of the pump through the pump shaft. The mechanical seal for pumps is a precise and complex structure. One of the basic mechanical components is a key component of pump machinery. What I want to talk about here is a mechanical seal mechanism for water pumps. [0003] The existing mechanical seal mechanism has certain disadvantages in use. The sealing effect is poor and cannot meet the needs of users. At the same time, the structure is not strong enough, it is very easy to be damaged, and the shock absorption effect is poor. The vibration caused the internal components to loosen and weaken the seal, which brought in...

Problems solved by technology

[0003] The existing mechanical sealing mechanism has certain disadvantages in use. The sealing effect is poor and cannot meet the needs of users. At the same time, the structure is not strong enough, it is very easy to be damaged, and the shock absorption effect is poor. The sealing mechanism is prone to failure due to long-term The vibration caused by the internal parts loosen and weakened the seal, which brings inconvenience to the users. Therefore, a mechanical seal mechanism for water pumps is proposed to solve the above problems.
