Advantages of spiral bearings

A) This type of bearing is made of spring steel. The annealing temperature of the spring is 3500C. Therefore, it is less sensitive than the temperature of the ball bearing steel (100C6) with an annealing temperature of 1800C. The data reaches the tempering temperature at the temperature. Above, the hardness will be extremely lost. Therefore, the spring steel is more suitable for high temperature operation.
B) The spring retaining steel has better elasticity; therefore, it is easy to install; the inner ring can be placed in any orientation by means of two hook wrenches; the inner tension of the inner ring can be fastened to the shaft. The inner ring of h9 or h1l is simpler to complete. This way the expensive processing cost on the inner ring can be saved.
C) This type of bearing is durable and has little effect on the weak acid formed by dust, iron filings, water and falling iron powder and water. The thin-walled spiral ring leaves a relatively large space for large-diameter rolling parts. The smashing and foreign matter can be tumbling into the spiral gap of the spiral ring. This keeps the movement of the bearing and keeps it clean during the transition.
D) The primary advantage of the helical bearing is that the outer ring can be reused repeatedly; this makes it possible to perform de novo machining once it is damaged and tortuous due to temperature. In this case, the bearing housing is also Demand adjustment. This layout layout design needs to be changed as long as the spiral outer ring instead of the whole set of bearings; all other bearing parts can be reused. The adjustment of the bearing seat is carried out by adding 1 mm of diameter on the diameter scale. For example: when the inner diameter is added from 105mm to 106mm; the outer diameter of the spiral outer ring also needs to be added to the device for lmm. This condition can be repeated until the diameter reaches 110mm. The bearing outer ring can be repeatedly processed 5 times. This can be a lot. Save money; especially if all other bearing components can be reused 6 times.
Mechanical parts: spiral seals spiral seals are non-touch type dynamic seals that use threads to impede liquid leakage. Also known as thread seals. Usually threads are machined on the rotating shaft of the seal. O-leakage of the liquid during operation and the housing are included. The space o constitutes a "liquid nut". The direction of the thread on the shaft causes the "liquid nut" to move axially when the shaft rotates. The liquid is continuously returned to the high pressure end. The spiral seal is suitable for liquid viscosity and has a small differential pressure. And medium speed occasions. Not subject to the temperature of the liquid.

The hot dipped galvanized steel water tank defers to the GB code 92SS177 manufactured new type water tank. The manufacture and the installment of tank have no influence of the construction. There are not needed the welding apparatus, the surface is hot dipped galvanize antiseptic treatment. It's artistic durable, prevents two times pollution to water quality and it beneficial to human health. The water tank meets the construction product standardization, the serration and the factorization request.
Hot Dip Galvanized Water Tank application:
1) Storage and regulation of living water supply & construction water supply;
2) Rainwater Harvesting & Storage;
3) Effluent / Acid and alkali solution treatment & storage;
4) Hosptial, buildings, building site, school and other place;
5) Temporary water storage for expansion of the heating system, condensate tank and construction, geological survey, industry, national defense project etc.
