With 3D printing technology entering the manufacturing industry, few factories have used this technology as well in the automotive industry. In fact, when it comes to the application of additive manufacturing technology, it is probably in addition to the medical and aerospace industries, the automotive industry. Some big companies like Ford and Rolls Royce, as well as professional racing teams and some start-up companies, regard 3D printing technology as a tool for designing complex components....
With the development and strength of related technologies, ultrasonic bottle washers have been widely used in the machinery industry, electronics industry, medical industry, semiconductor industry, etc., together with the corresponding cleaning agents can be used to clean all kinds of stains. The ultrasonic bottle washer is based on the principle of ultrasonic cavitation. When the bubble formed by the ultrasonic wave suddenly ruptures, more than 1000 atmospheric pressures will be generated....
What are the faults of mechanical seals? How to deal with it? The mechanical seal failure and treatment are as follows: First, the performance of mechanical seal failure on the parts: 1. Failure of the sealing end face: wear, hot cracking, deformation, damage (especially non-metallic sealing end faces). 2. Spring failure: relaxation, breakage and corrosion. 3, the failure of the auxiliary seal: assembly failures are falling, cracking, bumping, curling and twisting; non-assembled faults are...
Analysis of normal operation and failure of mechanical seals Hebei Innovation Sealing Material Co., Ltd. provides technical support: 1. Preparation and precautions before starting mechanical seals a. Thoroughly check the mechanical seals, as well as whether the attachments and pipelines are installed properly and meet the technical requirements. b. Perform a static pressure test before starting the mechanical seal to check for leaks in the mechanical seal. If there are more leaks, you should...
Comparison of mechanical seals and packing seals 1. Packing seal: The structure is simple, the price is cheap, and the maintenance is convenient, but the leakage amount is large and the power loss is large. Therefore, packing seals are used to transport general media such as water; not suitable for petroleum and chemical media, especially in expensive, explosive and toxic media. . 2 mechanical seal: The sealing is better, the leakage is small, the service life is long, but the price is...
[Principles and characteristics of mechanical seals and material selection] 1, the working principle of mechanical seal The mechanical seal is a shaft seal device that resists leakage by a pair of or pairs of end faces that are relatively slid relative to the shaft under the action of the fluid pressure and the elastic force (or magnetic force) of the compensating mechanism to assist in sealing. 2, the selection of commonly used materials for mechanical seals Clear water; normal temperature;...
1. After the new machine is working 250H, the fuel filter and the additional fuel filter should be replaced; check the clearance of the engine valve. 2. Daily maintenance; check, clean or replace the air filter; clean the inside of the cooling system; check and tighten the track plate bolts; check and adjust the track tension; check the intake heater; replace the teeth; adjust the bucket clearance; Front window cleaning fluid level; check and adjust air conditioning; clean the cab floor;...
My company specializes in providing four-column hydraulic seals and other products, our products are of reliable quality, high credibility, reasonable prices and widespread customer trust. The following introduces the seal mechanism principle of the four-column oil seal. 1. Overview: Hydraulic oil seals are sealing elements used to seal rotating shafts in mechanical equipment, and the cavity is essentially stationary. 2. Oil seal of the oil seal: static seal between the outer edge of the oil...
Mechanical seals, also known as end seals, have a pair of end faces that are perpendicular to the axis of rotation. The end faces, depending on the fluid pressure and compensating for the mechanical external elastic force, rely on the fit of the auxiliary seal to remain attached to the other end and slide relative to each other to prevent fluids. leakage. The failure of mechanical seal leakage is one of the most prone faults in pump failure. Therefore, the mechanical seal of the pump is also...
The skeleton oil seal should be made by the professional master. The excellent performance always appears in many different scenes and is a very stable fastener. The knowledge of the use of the skeleton oil seal needs to be understood by the purchaser, and the knowledge of the fastener will be well known. So, what are the common usage scenarios? Skeleton oil seal use The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too...

The screw elevator is the most widely used transmission component in the field of mechanical automation. Compared with the traditional transmission method, it is more convenient to install and use. Compared with the emerging electric push rod and electric servo cylinder, Its load and range of use are more advantageous, so the screw jack is very popular now, and has been recognized by many customers. The internal structure of the screw elevator is a worm gear structure. This mechanical structure...
With the support of the 863 project of the Ministry of Science and Technology and the National Natural Science Foundation of China, the team led by Academician Xue Qunji and Researcher Wang Liping from the State Key Laboratory of Solid Lubrication of the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences has obtained new research on high-hardness carbon-based coatings for mechanical seals. progress. Harsh environments and variable operating conditions (frequent start-stop,...
The leakage of hydraulic cylinder brings many hazards, which is not only one of the causes of various faults of hydraulic cylinder, but also an important factor affecting safety and polluting the environment, so it should be paid enough attention. [What are the causes of poor sealing of hydraulic cylinder] Poor sealing will cause external leakage and internal leakage. The causes of poor sealing are: 1. Seal is damaged due to improper assembly; 2. The assembly accuracy is poor, the clearance is...
The manufacturer of hydraulic cylinder must understand the sealing technology to select different seals according to different technical requirements. The seal manufacturer must also understand the working principle of the oil cylinder and adopt different designs to meet the technical requirements of the oil cylinder. Therefore, they need to closely cooperate to reduce the probability of oil cylinder failure. (1) When there is no device, the seal has four dimensions, which can be seen by...
