If centrifugal cryogenic pumps generate noise and vibration during operation, accompanied by reduced flow, lift, and efficiency, and sometimes fail to work, repairs often involve pitting or honeycomb damage near the entry edge of the blade, Serious when the entire leaves have this phenomenon, and even the leaves are penetrated, which is caused by cavitation damage. Centrifugal cryogenic pump cavitation causes: pump rotating impeller to work on the liquid, so that liquid energy increases. During...
Gearbox oil spill is a common problem, the oil spill may be due to box quality problems, the quality of oil, oil seal quality problems, the pressure inside and outside the box and other issues, the other if the oil filling too much can also lead to overflow. Reducer in the event of leakage should be based on the actual situation to take measures, here we introduce a simple method of treatment. If it is the quality of the gear reducer castings caused by the oil leakage, you can first use...
SB Series barrel pump (barrel pump, electric pump) can be directly inserted into the bucket (maximum suitable for GB / 325-1991 steel drums) to extract the liquid in the barrel. Can transport a variety of fuel, with corrosive chemical syrup, other liquids. According to the nature of the liquid transported, the pump wetted part of the material can be used aluminum alloy, high-quality stainless steel, polypropylene and other components. Drive motor is equipped with single-phase standard motor,...
All-welded ball valve is now widely used in the industry as a whole, while the degree of concern among users is also increasing year by year, it is based on the market demand for a product introduced to engage in the development and production of the company's products , Shanghai Wuyue Pump Manufacturing Co., Ltd. can be described as a well-known industry circle, and by the vast number of users of the trust and support. In the use of all-welded ball valve in particular should be noted that...
Tencent Digital (compilation: Mi Ke) Many music lovers have always believed that the men who play drums are the most handsome, but in a band, the drums can be said to be the largest and most inconvenient instruments. This is really inconvenient for those who like to play music or practice drums everywhere.

Hydraulic cylinder is the hydraulic system will be converted to mechanical energy hydraulic actuator. The failure can be basically summarized as a hydraulic cylinder malfunction, unable to promote the load and the piston slipping or crawling. As the hydraulic cylinder failure caused by the phenomenon of equipment downtime is not uncommon, therefore, should pay attention to the hydraulic cylinder fault diagnosis and use of maintenance work. The following is the hydraulic cylinder malfunction or...
If you pay attention, you will find that in many barrel-making enterprises processing steel drum bottom, top blank forming, will be coated with a layer of lubricant on the surface of the thin steel sheet, especially for hot-rolled steel sheet, if not coated In lubricants, most of the workpieces after stamping are cracked or cracked. So, why is there no cracking when it is coated with lubricant? This is because when the hot-rolled steel sheet, because the sheet cooling faster, so the temperature...

Second, the impact of the size of the bucket body blanking - overlapping wrong side In production, a large amount of leakage in the delta region was sometimes found. When we cut the curled section on both sides of the weld, we found that the weld was completely different on both sides. as shown in picture 2. One side of the roll is better, while the other side is extremely unsatisfactory, there is a clear lack of size flanging, so that the side of the weld curled triangle side leakage. In order...
With the rapid development of the modern petrochemical industry, some of the media used in special operating conditions are highly corrosive. Even stainless steel valves and lining rubber can not meet the needs of enamel valves. If the use of Hastelloy, Monel or Alloy No. 20 as the valve material, due to its large amount of Ni, Cr, Ti, Mo, Nb and Pt and other rare metals, its limited resources, expensive. According to the results of modern science and technology, fluorine plastic molecular...
