What size bearing puller do I need

2023-04-17 18:08:53 | geotextile

First and foremost, let's establish that there are two primary types of bearing puller sets: internal and external. An internal bearing puller set is designed to remove bearings that are inside a housing, such as those found in an engine block or transmission. On the other hand, an external bearing puller set is used to remove bearings that are on the outside of a shaft or housing, such as those found on wheels or pulleys.

When it comes to selecting the correct size of bearing puller, it's crucial to take into consideration the diameter of the shaft or housing that the bearing is seated on. Choosing a puller that is too small can cause damage to the bearing and surrounding components, while a puller that is too large may not fit properly or provide enough leverage to effectively remove the bearing.

So, how can you determine the correct size of bearing puller to use? One option is to consult the manufacturer's specifications for the specific bearing you are working with. Another option is to measure the diameter of the shaft or housing and compare it to the size range specified on the bearing puller set you are considering.

In summary, selecting the correct size of bearing puller is crucial for ensuring a safe and effective removal of bearings. Whether you're working on an internal or external bearing, be sure to consult the manufacturer's specifications or measure the diameter of the shaft or housing to determine the appropriate size of bearing puller set to use. Remember, a little bit of preparation and attention to detail can save you time, money, and frustration in the long run.


The influence of high and low temperature on hydraulic oil of brick machine

2020-05-21 15:50:08 | geotextile

Hydraulic oil plays the role of energy transfer, anti-wear, system lubrication, anti-corrosion, anti-rust and cooling in the hydraulic brick machine system. For hydraulic oil, the first hydraulic device should meet the operating temperature and starting temperature of the liquid viscosity requirements, each hydraulic oil has a certain range of use, too high or too low temperature on the hydraulic oil have a negative impact, so what is the impact of high and low temperature environment on the hydraulic oil? The influence of low temperature on hydraulic oil of brick machine 1. Low temperature makes hydraulic oil viscosity. If the viscosity is too high, the self-priming capacity of the oil pump will decrease, and the pressure loss and power loss of the hydraulic system will increase. It is generally believed that when the viscosity is ≥1000mm2/s, the hydraulic system cannot work normally, and when the viscosity is ≥2000mm2/ s, the hydraulic system cannot start normally. 2. Low temperature makes the water in the hydraulic oil of the brick machine solidify, and the solidified water is attached to the surface of the parts of the hydraulic valve and the oil filter, etc., which may cause the hydraulic valve to be stuck and the oil filter to be blocked, so that the hydraulic system cannot work normally. 3. Low temperature makes the rubber sealing material in the hydraulic system shrink and harden, reducing the sealing performance and even leading to seal failure. 4. Low temperature makes the hydraulic oil itself shrink, especially the brick machine hydraulic oil in the closed cavity shrink, so that the pressure drops and even produces negative pressure. The influence of high temperature on hydraulic oil of brick machine 1. The high temperature makes the hydraulic oil viscosity smaller, the viscosity is too low, the hydraulic system leakage increases, the efficiency drops, and even the hydraulic system cannot work normally. 2. High temperature makes the oxidation of brick machine hydraulic oil intensified, hydraulic oil gradually generated some ketones, acids and colloid, asphaltene and other substances, pollution of hydraulic oil, shorten the service life of hydraulic oil. When the brick machine hydraulic oil oxidation to a certain extent, hydraulic oil failure, can not be used. 3. High temperature causes the lubrication film formed on the metal surface of the friction parts to undergo chemical decomposition and the lubrication film is damaged. 4. High temperature will often lead to steel and other non-ferrous metals in the hydraulic oil corrosion intensification, resulting in surface damage to parts, corrosion at the same time. 5. High temperature is more likely to produce bubbles, which may damage the lubricating oil film, cause sintering or increase wear on the friction surface, and accelerate the oxidation and deterioration of the hydraulic oil, affecting the accuracy and sensitivity of the hydraulic components. In severe cases, it cannot meet the requirements of the hydraulic system. 6. High temperature makes the performance of rubber seals in the hydraulic system worse, which can make the rubber swell, become soft, accelerate the aging of rubber, and even seal failure. 7. High temperature makes the volume of hydraulic oil expand, so that closed in the cavity of the brick machine hydraulic oil pressure rise, causing danger.


Type of geomembrane

2019-04-04 14:42:12 | geotextile
At present, the production and application of geomembrane are developing rapidly, and there are many studies on geomembrane, but there are relatively few studies on the aging properties of geomembrane. Geomembrane as an engineering material, its aging performance indicators directly affect the life, safety and reliability of the project. However, many buyers are very concerned about textured hdpe geomembrane price. Therefore, the research on the aging properties of geomembrane has high economic and strategic significance.

The American Society for Testing and Materials (ASTM) defines geomembrane as Any textile that is used with foundations, soil, rock, earth, or any other civil construction material and that is part of a man-made engineering or system. Geomembrane is used together with foundation, soil, rock, soil or other building materials, and uses geomembrane to strengthen, protect, drain, filter, isolate, and prevent seepage. Geomembrane has been called “four major building materials” together with cement, steel and wood.

Geomembrane can be divided into woven geomembrane, knitted geomembrane and non-woven geomembrane according to different processing methods. The woven geomembrane is currently used in filament woven fabrics and flat woven fabrics, and the material is mainly polypropylene. The warp-knitted composite geomembrane is made of glass fiber (or other synthetic fiber) as a reinforcing material and is compounded with a staple fiber needle-punched nonwoven geomembrane. Non-woven geomembranes mainly include short-fiber needle-punched geomembrane and filament-spun clay film. The selected synthetic fiber raw materials are mainly polyester, polypropylene, nylon, etc., mainly polyester and polypropylene. So don't choose an inappropriate geomembrane because of the price of the geomembrane.

Whether it is knitted geomembrane, woven geomembrane or non-woven geomembrane, it is easy to be affected by internal factors and external factors during processing, storage and use, and its performance is gradually deteriorated, resulting in the final loss of use value. For aging. This is a common problem in geomembranes. Its essence is the breakage of molecular chains in polymer structures, changes in chemical structure, etc. Macroscopically, it shows the decline of geomembrane strength and macrostructure damage, which is an irreversible change.

Geotextiles and geomembranes are commonly used in geotechnical materials. They are commonly used waterproof materials. Because there are many similarities between the two, and the names are very similar. As a professional smooth pond liner hdpe geomembrane supplier, below, we will introduce geotextiles for everyone. And the performance of geomembranes.

Geotextiles, as the name suggests, are made of non-woven fabrics. They are mainly used to reinforce foundations. Geomembranes are made of high-density polyethylene and are mainly used for seepage prevention. The combination of the two is a composite geomembrane, which is divided into a film and a film. Two cloths and one membrane have stronger anti-seepage performance. The high quality non woven geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers by needle punching or weaving. It is a member of the large family of geosynthetic materials. It is widely used in highway, railway, water conservancy, large-scale construction, power plant ash dam construction, non-ferrous metal tailings treatment, environmental protection engineering, soil and water conservation, etc.

The high quality textured hdpe geomembrane is a plastic film. Geotextile is a member of the large family of geotextiles and geosynthetics. It is widely used in highways, railways, water conservancy, large-scale construction, power plant ash dam construction, non-ferrous metal tailings treatment, environmental protection projects, Soil and water conservation, etc. Geomembrane uses plastic film as the anti-seepage substrate, and the geotextile material composited with an on-woven fabric, its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film.
