Description
Technical field:
The utility model belongs to the seal arrangement technical field, refers in particular to the mechanical water pump sealing.
Background technique:
The sealing medium of water pump is generally general weak corrosion liquid such as muddy water, sewage, solid particle.At present, the mechanical seal device of water pump has a lot of deficiencys, as the instability that turns round, problems such as the oiling agent leakage rate is big perhaps in operation process, are subjected to the influence of the frequent change of motor speed, static seal, under motive sealing and the spring tension acting in conjunction, seal face is easy to generate fluctuation, makes to be subjected to equilibrant irregular stability decreases, sealing medium also can enter on the seal face, particle and seal face produce friction, destroy or the damage motive sealing, cause seal failure, shortened the life-span of mechanical seal, perhaps, lost the effect of motive sealing and shaft seal, do not reached and the pump shaft synchronous speed along with the wearing and tearing or the distortion of rubber seal seat, motive sealing and pump shaft friction cause the damage of pump shaft, sealing state is destroyed, the adverse consequences that causes pump to burn, thus influenced working efficiency; The stationary ring cover is separate individuality with stationary ring, when mounted, turn in the meeting of stationary ring cover to make imbalance is installed, tell running for a long time at pump, expansion during friction-produced heat energy or because of the intrusion of the extraneous liquid of operating mode reason to the variation that product physics, chemical property produce, product is produced run, skidding.
Summary of the invention:
The purpose of this utility model provides a kind of good sealing effect, and stable performance is simple in structure, and is easy for installation, and can save the mechanical water pump sealing of cost.
The utility model is achieved in that the mechanical water pump sealing, it is characterized in that: on pump shaft, be positioned with transmission ring by locating stud, two ends at transmission ring are symmetrically arranged with motive sealing and static seal laterally, between two motive sealings, the outer surface of transmission ring is provided with spring, described static seal is for being connected with stationary ring at stationary ring cover internal fixation, described motive sealing is for to be disposed with moving-coil and rotating ring in the mesopore of rotating seat, to transmission ring two side directions, rotating ring contacts transmission ring and rotating seat relative positioning with the stationary ring sealing.
Above-mentioned rotating seat is meant being positioned with transmission ring by locating stud on the pump shaft: radially be provided with screw on transmission ring, by locating stud transmission ring be tightened on the pump shaft in screw.
Above-mentioned transmission ring and rotating seat relative positioning are meant: the outer surface at transmission ring is provided with groove, the rotating seat that is arranged on the transmission ring both sides all stretches into the relative positioning that engagement floor in the groove of transmission ring is realized transmission ring and rotating seat by it, meshes the external diameter of the internal diameter of floor less than rotating seat.
Above-mentioned moving-coil is the O RunddichtringO.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model is installed by two static seals, motive sealing symmetry and transmission ring and spring are set between motive sealing, and is easy for installation, improved work efficiency of workers widely;
2, the utility model is simple in structure, has reduced cost of production;
3, the utility model adopts rotating ring, rotating seat, moving-coil to be connected as a single entity, and makes pump that compact effect be arranged when starting or shut down, can work done does not produce the percussion of certain fulcrum, the working life of having improved product greatly to product because of instantaneous starting.
