Spring seals factory supplier by dmsseals.com
4 min readHydraulic seals manufacturer by Dmsseals: A basic mechanical seal contains three sealing points. The stationary part of the seal is fitted to the pump housing with a static seal –this may be sealed with an o-ring or gasket clamped between the stationary part and the pump housing. Rotating and Stationary parts of a Seal – The rotary portion of the seal is sealed onto the shaft usually with an O ring. This sealing point can also be regarded as static as this part of the seal rotates with the shaft. The mechanical seal itself is the interface between the static and rotary portions of the seal. One part of the seal, either to static or rotary portion, is always resiliently mounted and spring loaded to accommodate any small shaft deflections, shaft movement due to bearing tolerances and out-of-perpendicular alignment due to manufacturing tolerances.

A mechanical seal is a very effective device. Every centrifugal pump must accommodate a spinning shaft while mechanically maintaining fluid or gas contained in the “wet end” of the pump. Mechanical seals consists primarily of a rotary seal face with a driving mechanism which rotates at the same speed as the pump shaft, a stationary seal face which mates with the rotary and is retained using a gland or in some pump models an integral stuffing box cover, a tension assembly (utillizing springs or a metal bellows) keeps the rotary face firmly positioned against the stationary face preventing, excluding, and containing contamination and leakage, both when the pump is not in operation and when the pump shaft is rotating. Static sealing gaskets, orings or elastomeric bellows are strategically located to complete the seal assembly.
Although construction machinery looks extremely complex, the common characteristics that can be summarized are: Usually work outdoors. The work site often changes, and some can move by themselves. The working environment is usually dusty or stained. Nowadays, construction machinery generally adopts hydraulic transmission, because hydraulic transmission has the following obvious advantages compared with mechanical transmission: The power-to-volume ratio is large and the location arrangement is easy. It can realize stepless speed change. It is easy to realize overload protection. Less shock, vibration and noise.
The radial force of our rotary seals on the shaft and the distribution is very reasonable. It can achieve the optimal “critical oil film thickness” working condition and always maintain critical lubrication. We guarantee that our rotary seal can help the machine get the sharpest “peak” pressure distribution with the least radial force, providing the best sealing effect. The bearing seal is designed by DMS SEALS to isolate the moving metal part, guiding the piston and piston rod of the hydraulic cylinder to move in a certain direction and it can help withstand lateral loads. It helps prevent any direct contact between the piston metal and the cylinder metal and prevents strain and seal damage on the inner surface of the cylinder.
Sealing performance over conventional O-rings is achieved by reducing particle generation, extending seal life and minimizing replacement time during preventive maintenance. Compared to traditional O-rings, this seal effectively reduces the number of dust particles generated during operation and extends the life of the machine with bonded seals installed. The seal has a working diameter range of 6.5 to 60.58mm.
DMS Seals piston seals can be used very effectively in the clearance between the two chambers of the hydraulic cylinder and cylinder. The piston seal is pushed by the pressure of the fluid. Its good working performance can improve the efficiency of the machine. Due to its excellent resistance to leakage, it helps the machine to extend the machine’s working life. Our seals provide the best tight adhesion for the sealing system with low internal leakage and frictional resistance.
Destroy the leak: The working conditions of the sealing part are relatively bad, the thermal deformation is large, it is often subjected to vibration, impact, improper installation, excessive tightening force, repeated use, compression deformation, internal stress concentration, damage beyond the fatigue strength, material aging, deterioration, etc. will cause damage to leaks. This kind of leakage has the greatest impact and great harm, so it is necessary to strengthen prevention.
