Share common sense mechanical seal mechanical seal manufacturer

Mechanical seal based components, precision, complex mechanical response was synthesized with a variety of pump, reactor, turbo compressor, submersible motor equipment such as key components. Sealing performance and service life depends on many factors, such as selection, accuracy, correct installation and use of the machine. Basic knowledge of the mechanical seal mechanical seal manufacturer 1, the basic concept of mechanical seal: mechanical seal by at least a pair of end face perpendicular to the axis of rotation of fluid pressure and compensation unit elasticity ( Or magnetic) The definition and the auxiliary coordinate keep has been Posting joint sliding device, to prevent fluid leakage. Auxiliary seal ring compensation is called metal bellows mechanical seal. 2, the composition of the mechanical seal: there are four main parts. 一个。 Seal: ring. B。 The second seal: seal. C。 Compact: springs, push the ring. D。 Transmission: play A market town and bonds or fixed screw should be paid attention to problem 1, the points for attention during the installation of A, must be taken to avoid installation to install the deviation ( 1) Tighten gland should be after the found that the coupling bolts should be uniform, prevent the oblique end of the gland, using a feeler gauge checkpoints, the error is less than zero. 5 mm. ( 2) Check the glands and shaft or hollow shaft diameter ( Concentricity) , uniform clearance, surrounded by using a feeler check tolerance is less than 0. 01 mm. B, the spring compression, according to the regulation, don't allow too big or too small, need the error of 2. 00 mm. Increase the surface pressure and velocity on the surface of wear and tear. Is too small will not help the lack of pressure to seal. C, ring beard installation is complete, press ring should be automatically returned by the spring shaft flexibility. 2, remove notice A, carefully remove the mechanical seal, it is strictly forbidden to use A hammer and A shovel, so as not to damage the seals. Do a line hook, self-raised funds gap to the driver's seat, pull direction seal. If dirt removal is not suitable for, should be cleaned thoroughly after dismantled. B, if the pumps with mechanical seal at the end of two, in the assembly, take care of each other in the demolition, in case of loss. Should not tighten C again, running mechanical seal, the hat, loose seal, ring parts must be replaced, you can continue to use. Compromise, because after the principal, friction pair in the original path, if you want to change, the interface is easy to seal. 3, mechanical seal 1, normal operation and maintenance of the preparations and preventive measures before the start of A, mechanical seal, as well as auxiliary equipment and pipeline installation of comprehensive review has been completed, conform to the technical requirements. B, before beginning the hydrostatic test, check the mechanical seal mechanical seal leakage. If more leakage, should find out why try to eliminate. If still invalid, you should delete check and reinstall. 2 ~ 3 for general hydrostatic test pressure kilogram per square centimeter. C, according to the direction of rotation of the pump, check whether the light evenly. Such as hard or fixed, you should check whether the assembly dimension error, installation is reasonable. 2, installation and retired A, should keep A sealed cavity filled with fluid before start. For conveying under freezing medium, steam seal cavity medium heat to melt. Before your car, in order to prevent sudden start software cycle lead to fragmentation. B, the sealing oil system, the use of mechanical seal of pump should be started from the sealing oil system. Park last stop seal oil system. C, heat pump after interruption may not immediately stop the oil seal cavity and cooling seal, should be closed area when the oil temperature is lower than 80 degrees, can stop the cooling water, so as not to damage sealing parts. 3 A, after running pump start slight leakage phenomenon, should abide by some time. Four hours of continuous operation, still cannot reduce leakage, you should stop the pump to check. B pump pressure should be stable, the pressure fluctuation is not more than 1 kg per square centimeter. C, pump in operation, should avoid to take this kind of phenomenon, in order to avoid dry, seal the seal face failure. D, often should check the sealing. More than standard operation, when the leak, crude oil is not more than 5 drops per minute, light oil is less than 10 per minute, etc. 2 - 3, there is still no improvement, you should stop the pump plug check the sealing device.
