What is the function of the sealing ring of the crusher?
Mechanical seal work should pay attention to the problem 1, installation precautions a, we must pay great attention to avoid the installation deviation generated in the installation (1) should be aligned on the gland in coupling bolts should be uniform, to prevent the end cap oblique, with feeler check, the error is less than 0.05 mm. (2) clearance check the gland and the shaft or shaft diameter (i.e. concentricity), around to evenly, not more than 0.01 mm check with the feeler the tolerance. B, spring compression amount should be carried out according to regulations, not allowed to have too large or too small phenomenon, requiring 2 millimeters of error. Excessive assembly increases the face to face pressure, and the other speeds end wear. Too little will cause less pressure than sealing. C, the ring should be installed to ensure flexible movement on the axis, the moving ring pressure to the spring, it should automatically bounce back. 2, the demolition notice in a, removing mechanical seal carefully, prohibited the use of hammer and chisel, so as not to damage the sealing element. The utility model can be used as a pair of steel wire hooks, and the sealing device is pulled out when extending into the gap of the driving seat in the direction of self profit and loss. If the scale is not removed, it should be cleaned and then removed. B, if both ends in the pump with mechanical seal, take care of each other in the assembly, the disassembly process, prevent the care for this and lose that. C, the running mechanical seal, where the gland loose, so that the sealing movement, the dynamic ring parts must be replaced, should not be re tightened, continue to use. Because in the kind of dynamic friction Ying, the original orbit will change, the contact surface of the seal is very vulnerable to damage.
Mechanical seals, mechanical seals are mainly composed of the following four categories. 1. Main seals: moving ring and stationary ring. 2. Auxiliary sealing parts: sealing ring. 3, pressing parts: spring, push ring. 4, transmission parts: play skip and key or fixed screw.
The basic concept of machinery, mechanical seal is defined by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or force) the role of the device and auxiliary seal with maintaining relative sliding postmerger and constitutes to prevent fluid leakage. The auxiliary seal of the compensating ring is metal bellows, and is called bellows mechanical seal.
