How to quickly solve the problem of corrosion and wear of diaphragm pumps with polymeric ceramic particle glue? Problems such as corrosion and cavitation are common in the use of diaphragm pumps. In view of the wear and corrosion of the diaphragm pump, the wear part of the diaphragm pump is repaired on site with NPT polymer ceramic particle glue. 1. Inlet and outlet repair process: (1) Construction conditions: 1. The surface temperature of the substrate must be 3°C higher than the dew point temperature, and the relative humidity must be less than 60%. 2. It is recommended to carry out construction at an ambient temperature of 15°C to 32°C. (If there is heating equipment, the workpiece can be heated to the sizing temperature corresponding to the wear-resistant and anti-corrosion coating of the equipment) (2) Surface treatment: 1. Welding: Repair welding equipment to erode the defect. 2. Surface cleaning: 1) Wipe the surface of the workpiece with acetone or degreasing cleaner to remove grease and sundries. 2) Use special equipment to dehumidify the surface of the workpiece. 3. Sand blasting and rust removal: remove the oxide layer on the surface of the workpiece, and the uniform metal color can be seen on the sandblasted surface. (3) Sizing process. 1. Sizing ①The tailings wear is light: Preheat the sandblasting equipment, mix the components A and B of the NPT-J-14 wear-resistant and anti-corrosion coating evenly according to the weight ratio, and apply them to the wear parts of the equipment. ②. The middle mine is seriously worn: NPT-YHL-J-1.0-2.0 equipment wear-resistant and anti-corrosion coatings A and B components are mixed evenly by weight and applied to the severely worn parts of the equipment. 2. Heating and curing: place the workpiece in a heating furnace to reach 120 °C, and time it for 3 hours to achieve complete curing; (4) Grinding acceptance. 1. Grinding: The workpiece after heating and curing is strictly ground according to the size of the workpiece, and it is ground to the standard size; 2. Topcoat treatment: Mix and stir the equipment repair topcoat according to the proportion, and apply it evenly on the surface of the workpiece with a plastic scraper to make the surface smooth; 3. Acceptance: Assemble according to the equipment assembly standard to meet the normal use standard; 4. Painting: After passing the inspection, the workpiece is painted, and the surface of the painting is required to be uniform, and sagging is not allowed. vacuum pump in the production of ketene of application 2BE3 Series Liquid Ring Vacuum Pump

The vacuum pump can meet some requirements in the process of use, but in the production process, it must be operated in strict accordance with the operating regulations to achieve good results. Let's understand the reasons for the insufficient sealing of the vacuum pump. In the process of using the vacuum pump, the vacuum pump will be damaged due to environmental or manual operation. Microbial sludge is less polluted and filled with yellow voids, which damages the compensation effect of yellowing on the sealing performance, increases the damage of cyclic dynamic and static friction, and affects the sealing performance. It may be necessary for the operator to disassemble and inspect the vacuum pump once a quarter. The addition of organic chemicals will lead to slow corrosion of vacuum pump sealing ring and seal failure. Therefore, before applying it to operation, the manufacturer of the vacuum pump must be asked which medium can be used. The working fluid of the vacuum pump often contains toxic particles, bacteria, microorganisms, sludge, calcium ions and related organic chemicals, which erode the metal parts of the machine seal, which will damage the sealing performance of the vacuum pump seal. In the process of filling the upstream and downstream catalyst supports, most of the soot is removed by brushing and other processes, but with the increase of operation time and the corrosion of materials in the cyclone separator, new smoke and dust will inevitably be generated. The dust in the vacuum pump can easily damage the sealing position of the mechanical seal, which needs regular maintenance and cleaning. The carbon dioxide and reducing materials in the working fluid of the vacuum pump reflect that the converted calcium bicarbonate has damaged the seal of the machine. This is inevitable, but regular maintenance can be carried out to avoid these problems as much as possible. The above are the reasons for insufficient sealing of vacuum pump. During the operation, the operation must be carried out in strict accordance with the laws and regulations.
