What is the maintenance and application range of rubber pipes
In daily life, we can often see rubber tubes, its appearance has brought us great convenience, but how do we maintain it in daily life? What is the scope of its application? Below, our staff will give you a brief introduction to the relevant knowledge points. Cleaning: It is recommended that you empty the rubber hose after use. It should be cleaned if necessary. Inspection: The rubber tube must be inspected after each use to ensure that there is no structural damage.
How to prevent oil leakage accident of black high pressure hose
Nordson What is the use of black high pressure hose? The black high-pressure hose structure is mainly composed of an inner rubber layer, a middle rubber layer, a four-layer or multi-layer alternately wound steel wire reinforcement layer and an outer rubber layer. The inner rubber layer has the effect of making the conveying medium withstand pressure and protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, and the steel wire (Phi 0.3-2.0 reinforcement layer) layer is the skele
Wire braided hose products related introduction
It is mainly used in the hydraulic system of aircraft fuel, mine hydraulic support, oilfield mining, construction machinery and equipment, which is used to transport high temperature and high pressure kerosene, oil, red oil (flammable and explosive media), and realize the pressure service transmission series products. Product structure: It is mainly composed of liquid resistant synthetic rubber inner layer, medium rubber layer, Ⅰ, Ⅱ, Ⅲ layer of wire braid layer, weather-resistant synthetic rubber outer layer, the inner rubber layer has the effect of making the conveying med
Rubber particles cause rubber aging
A) Oxygen: oxygen in rubber with rubber molecules free base chain reaction, molecular chain fracture or excessive crosslinking, causing rubber properties change. Oxidation is one of the important reasons for rubber aging. B) Ozone: Ozone chemical reactive oxygen is much higher, more destructive, it is the same to break the molecular chain, but the effect of ozone on rubber varies with rubber deformation or not. When used as a rubber for deformation (mainly unsaturated rubber), cracks appear in the direction of direct stress action, that is, the so-called "ozone cracking"; When acting on
The clauses in the inspection objectives of the ultra-high pressure hoses are formulated in relevant parts According to the rule requirements of the "High Pressure Water Jet Cleaning Safety Standard", the high pressure hose should reach the following target requests: 1) The explosion pressure should reach more than 2.5 times the working pressure. 2) The experimental pressure should reach 1.5 times the working pressure, and adhere to this pressure for more than 2 minutes without damage. 3) Pulse pressure should be in the range from zero to working pressure, 50,000 pr
High pressure hose joint form and cone sealing precautions
First, the hose joint form can be roughly divided into internal thread form and external thread form 1) Internal thread form This structure is generally suitable for the occasion of low working pressure and large flow rate, this connection mode allows the diameter of the hose to be appropriately increased, and its sealing mainly depends on the sealing ring. 2) External thread form This structural form is mainly used in the case of high pressure, and most of the working pressure exceeds 1800bar. This connection method is to press the locking nut through the external
Maintenance of rubber tube after installation
1. It is very important to accurately use the rubber hose to determine the length of the rubber hose you need, and it is also necessary to check whether the application conditions of the rubber hose meet the requirements of the selected rubber hose. You should ensure that the rubber tube you will use is the most suitable. The working pressure and suction value should be carefully determined. In particular, it should be noted that the change of the testing standard pressure of the wear-resistant sandblast pipe or the peak pressure exceeding the promised maximum value will greatly shorten the li
Liquid specific gravity balance manufacturers on the external factors of liquid density measurement
Liquid specific gravity balance manufacturers analyze the external factors of liquid density measurement: 1. Temperature: when the temperature of organic compound liquid rises or falls, due to the relationship between thermal expansion and cold contraction, the volume of liquid will expand or shrink, and the density of liquid will also decrease or increase. 2. Pressure: when the pressure of organic compound liquid increases or decreases, the volume of liquid will also have a slight tendency to decrease or increase, but the range of change is much smaller than that caused by tempe
Summary of mixing process of powder metallurgy densitometer and powder metallurgy
Because the pore structure of powder metallurgy has a great influence on the physical properties of powder, and powder metallurgy products according to its needs are bulk density, wet density, apparent porosity, oil content rate as the main identification criteria, so the density detection of forming body and sintered body is particularly important. According to the characteristics of powder metallurgy industry, the electronic powder metallurgy densitometer has been widely used in powder metallurgy industry. It only takes two steps to read the density value directly, which saves

Effect of bubbles on the surface of sample on the measurement of plastic particle density tester
Plastic particle density tester to measure the density of plastic particles, the most widely used in rubber, plastic and other industries, but in the measurement often encounter small bubbles on the surface of the sample, many people do not care about such a phenomenon, in fact, attached to the surface of the bubble on the sample density measurement results is quite large. Why emphasize the effect of air bubbles on the density of plastic particles? 1. Measuring the density of plastic particles, accumulated experience for a long time. 2. Because the measurement plastic is t
