high quality rubber liner It will burst for a long time due to frequent and severe pressure shocks. This situation is usually not caused by excessive static pressure, but is related to the strength and frequency of pressure shock. During the operation of construction machinery, the oil pressure in the oil resistant hose will rise or fall repeatedly, and then it will form frequent pressure shocks to the oil pipe, causing the oil seal of each part to become more damaged, the oil resistant hose will bubble and break, and the pipe joint will become loose and leak. Therefore, in the process of operation, the valve rod should not be pulled too hard, and it needs to be gentle. The application temperature of the oil in the oil resistant rubber hose is too high, resulting in aging and bursting of the rubber hose. During the operation of construction machinery, the hydraulic system will cause the oil to become hot due to power failure, and the influence of external temperature (especially in summer) will cause the oil temperature to rise sharply. The higher the oiling temperature is, the easier the rubber hose ages, the worse the elasticity is, the lower the strength and sealing function are, and the oil resistant hose will burst quickly. Therefore, rubber liner Where can I find it? During operation, when the temperature rise of the hydraulic system is too high or too fast, the causes should be found and eliminated in time. Necessary cooling measures shall be taken for summer operation, especially continuous operation.

For the woodworking industry, many users high quality rubber liner Not unfamiliar, this is an industrial dust collector used on woodworking carving machines, mainly used to absorb wood chips, wood ash, etc. At present, there are many kinds of woodworking vacuum tubes on the market. In the past few years, major furniture factories used PVC steel wire hoses with flat ends. In recent years, more and more enterprises have replaced cheap PVC steel wire hoses with more wear-resistant and durable pu steel wire expansion tubes. Some of the former take a few days or a month, while some of the latter take a few months or a year, They are also steel wire hoses. Why is the service life gap so far? First of all, you may have the impression that many PVC hoses have a very bad smell. This kind of hose is often used in daily life. Because the raw material itself is very cheap, the price of the finished product is also very low. For example, only a dozen yuan a piece. Think about the price of PVC raw materials, which is generally 8-15 yuan a kilogram, And most businesses will not use expensive PVC raw materials, rubber liner Where can I find it? The woodworking vacuum tube produced in this way has a very strong smell, not only unpleasant, but also many times the product can not even achieve environmental protection. However, the current updated product, pu steel wire telescopic tube, is a large woodworking furniture factory. An expensive woodworking carving machine uses a cheap vacuum tube with a very smelly smell, which has much to do with the overall style.

doy rubber liner Main impact: The air volume loss of the whole system is too large to meet the air volume requirements, and the power is seriously wasted. 1. If the stainless steel welded air duct system adopts the combined flange air duct, it may be that the seam, flange strip seam and hole seam are not sealed with sealant; The allowance of segment blanking seaming is greater than the specification requirements. 2. No embedded parts are set at the joint of brick structure air duct and metal air duct, or the sealing gap is too large or the joint is not tight. Countermeasures: 1. Button type seaming can be used for medium pressure air duct; Corner seam or joint corner seam shall be used at four corners of high-pressure air duct or clean system air duct. 2. Seams of stainless steel welded air ducts, joints without flange inserts and holes must be sealed with sealing paste to prevent air leakage. 3. During construction, embedded parts shall be set at the junction of brick, structural air duct and metal air duct as required, or the civil engineering unit shall cooperate to block and seal to ensure close connection. During the air duct anti-corrosion treatment, the next anti-corrosion treatment can be carried out after the previous paint is dried; It is strictly forbidden to work without certificate. The duct type air outlet is a central air conditioning terminal air supply system that integrates the functions of air outlet, air supply pipeline, static pressure box, thermal insulation material, air valve, etc. rubber liner Where can I find it? Calculation of air duct size of stainless steel welded air duct: the equal damping method (equal pressure method) is a convenient calculation method, which is suitable for many occasions.

“ high quality rubber liner What are the applications in engineering transformation? " In this issue, we will explain this problem for you. Those who have consulted this problem will come to see it: First, we should consider the water supply and drainage of all water related equipment, such as wells, pumps, etc., their location, installation method and temperature, including galvanized air ducts. 2、 It is very important to consider galvanized air duct in advance to avoid temporary replacement of galvanized air duct materials. 3、 After the location of the machine tool is determined, the drainage outlet can be considered to be arranged underground, which is not only convenient but also durable. 4、 After river reconstruction, there should be a suppression test, but now many construction teams do not suppress the test. It is usually said that it is not important, that there is water and pressure in the galvanized air duct, and so on. Try to be present to suppress the test. 5. If the installation is completed, pay attention to the inspection of the workshop, water pump room and FRPP drain. If the drainage system is slow, the installation program should be able to open the installation. Water outlets should be protected, especially during civil engineering construction, rubber liner Where can I find it? It may cause soil loss and blockage. I believe that you have a better understanding of this information, and we will continue to improve the galvanized air duct to make it more widely used.

doy rubber liner With the continuous updating of technology, the products are also developing in the continuous updating. At present, the inspection requirements of rubber hose are also improved compared with the previous ones. The inspection index of ultra-high pressure hose shall meet the following index requirements according to the requirements of the Safety Code for High Pressure Water Jet Cleaning Operation: 1) The bursting pressure shall be more than 2.5 times of the working pressure. 2) The test pressure shall be 1.5 times of the working pressure, and the pressure shall be kept for more than 2 minutes without damage. 3) Pulse pressure shall be within the range from zero to working pressure, and 50000 pressure pulses shall be free of damage; The pulse frequency is 15 times/min when the working pressure is 1000-2800bar, and 110 times/min when the pressure is above 2800bar. Since high-pressure cleaning machine has been widely used in all walks of life, and the working condition of high-pressure hose is relatively the worst, we must pay attention to the quality when selecting high-pressure hose, so as to avoid unnecessary safety accidents. rubber liner Where can I find it? The development of rubber hose can not be separated from cooperation, R&D and innovation can not be separated from communication, and the inspection requirements of rubber hose have been improved compared with the previous ones. The storage site shall be free of ozone, heat source and equipment generating electromagnetic field. The coiled hoses or hose assemblies shall be stored horizontally, and the stacking height shall be limited to the extent that the products at the bottom will not produce permanent deformation.

doy rubber liner Compared with rectangular duct, it is widely used in the ventilation industry. Why? Let's start with its advantages to solve this problem and make it clear. At the same time, through the following introduction, I hope you can know more about the spiral duct and make yourself more professional in this regard. Now let's understand the function of air duct: function 1: air supply and ventilation. It is used to transport fresh air and waste gas, exhaust harmful gas, and deliver outdoor fresh air to the room. Generally speaking, spiral air duct is good. If the environment is humid or corrosive, stainless steel shall be used to avoid rust and corrosion of air duct. Function 2: provide cold air. It is mainly used for central air conditioning, but thermal insulation materials need to be added on the air duct. Function 3: Exhaust lampblack: It is mainly used to exhaust kitchen lampblack in restaurants, hotels and other places. Generally, circular air ducts are used. Function 4: dedusting and bulk material conveying: in the factory workshop, the air duct is used for dedusting, and the spiral air duct can be used for conveying particles, such as foam plastic particles, because rubber liner Where can I find it? The proportion of products is small. 1) Under the same plate thickness and pipe diameter, the strength of spiral air duct is higher. (2) Under the same section, the structural tension of spiral air duct is more reasonable, the stiffness is better, and the noise and vibration can be greatly reduced. (3) At the same length, the number of flange connections of spiral air duct is less, which can greatly improve the ventilation quality of the system.
