Hunan Sand suction hose The entry threshold is low, the industry market is mixed, and small enterprises with small scale, lack of core competitiveness and low technical level can be seen everywhere. Most of these enterprises lack brand awareness, and there are many brand names and unlicensed products. It is difficult to form enterprise influence through brands, and it is more difficult to improve product added value through brands. If the metal hose wants to take the road of high-end, it must improve both inside and outside. A good brand image promotion and influence building can certainly provide a strong driving force for the development of enterprises, but the root of this driving force lies in the high quality of the metal hose products themselves. Tongfeng Metal Hose said that in the future, domestic metal hose products will focus on high precision, high efficiency, high firmness, multi-function, multi specification, multi variety standardization, serialization and generalization to show their characteristics. One of the main reasons why China's metal hoses have been in the low-end state for a long time is the lack of independent research and development of products. On the one hand, the homogenization competition is serious. In order to win consumers, metal hose enterprises have long focused on low-cost competition and low price shopping. As a result, many enterprises only focus on the production and marketing of low-end products, ignoring the upgrading and innovation of product technology. on the other hand, Sand suction hose Where can I find it? ZHUANLI's weak awareness of protection and the serious phenomenon of technology plagiarism and infringement in the industry make the technology cost invested by many enterprises more than worth the cost, which has seriously hit the enthusiasm of metal hose enterprises for innovation.
wear-resisting Sand suction hose It is a key component of any hydraulic system. When they fail, everything will stop. The preventive maintenance of the metal sandblasting hose is very important and needs to be checked regularly in order to find problems before starting. This may include checking hose caps and fittings, and looking for other signs of leaks and impending hose failure. The more strict the hose inspection process, the more reliable your equipment will be. 1. Benefits of preventive maintenance of metal sandblasting hoses: preventive maintenance of metal sandblasting hoses and equipment is always better than reactive maintenance. One reason is that it can make your equipment run efficiently by solving problems before they fail and have a significant negative impact on the system. Contrary to what many people think, preventive maintenance means reducing downtime due to unexpected component and system failures. Attention to maintenance can also extend the expected life of equipment, maximize its economic value, and minimize potential safety hazards to personnel. Finally, preventive maintenance can reduce maintenance costs and unnecessary equipment procurement. Not participating in regular preventive maintenance can be an expensive decision. 2. Maintenance time of metal sandblasting hose: Sand suction hose Where can I find it? Part of the preventive maintenance program for solid metal sandblasting hoses includes periodic inspection of metal sandblasting hoses. Fixed equipment shall be inspected every three months. For mobile equipment, hose inspection shall be conducted every three months or every 400 to 600 hours, whichever comes first.
1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Sand suction hose Where can I find it? Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Hunan Sand suction hose The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.
Hunan Sand suction hose There are many specifications. Different installation positions require different specifications of cloth clamping sand blasting pipe, and the specification selection of cloth clamping sand blasting pipe has different requirements. The following small series will briefly introduce them to you: 1. Temperature: The selection should be based on the ambient temperature when the cloth clip sandblasting pipe is working. In case of high temperature, the temperature correction pressure shall be determined according to the working pressure and temperature correction coefficient of the cloth sanding pipe under high temperature to determine the correct pressure level. 2. Pressure: when selecting the cloth clip sandblasting pipe, check the nominal diameter and pressure gauge of the corrugated cloth clip sandblasting pipe according to the actual working pressure of the hose to determine whether to use the stainless steel mesh sleeve type. 3. Size: select the joint type, size of cloth sanding pipe and hose length according to the size of cloth sanding pipe. 4. Medium: determine the material of each part of the hose according to the chemical properties of the material medium transported in the cloth sanding pipe and the corrosion resistance of the hose material. 5. Status: According to the use status of the hose, refer to the correct use and installation method of the cloth clip sandblasting pipe and the length of the hose in the settlement compensation. Therefore, Sand suction hose Where can I find it? According to the actual pressure of the system, the higher the working pressure of the cloth clamping sand blasting pipe is, the normal operation of the system can be ensured, and the appropriate cloth clamping sand blasting pipe is selected.
