Mechanical sealing mechanism for water pump

Abstract

The invention relates to the technical field of mechanical sealing, and particularly relates to a mechanical sealing mechanism for a water pump. The mechanical sealing mechanism for the water pump comprises a connection seat and a lower shock absorption sealing seat, wherein a connection screw is arranged on the outer surface of the upper end of the connection seat, and an upper sealing seat is fixedly installed at the lower end of the connection seat; a hoisting ring is fixedly installed on the outer surface of the upper end of the upper sealing seat, and an auxiliary support column and a sealing bin are arranged on the outer surface of the lower end of the upper sealing seat; the sealing bin is arranged at one side of the auxiliary support column; and a limit hole is formed in the outersurface of the front end of the sealing bin. The mechanical sealing mechanism for the water pump is provided with the hoisting ring, the auxiliary support column, a first auxiliary sealing ring and alower shock absorption sealing seat, and a user can be facilitated to transport the sealing mechanism; and meanwhile, the sealing mechanism is more stable in structure, better in sealing performance,better in shock resistance, and applicable to different working conditions, and brings a better use prospect.

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.
