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

During the operation of the imported vacuum pump, sometimes the vacuum degree of the imported vacuum pump is low. So, how can we find out the cause of the problem and solve the problem? Let's take a look: 1、 Air leakage of inlet vacuum pump 1. The sealing ring leaks. Check the sealing condition of all seals and replace damaged sealing rings. 2. The gasket of ballast valve is damaged or not tightened. The gasket should be replaced and the ballast valve tightened. 3. The exhaust valve is damaged and the seal is not good. The valve plate should be replaced. 4. The diaphragm is pressed too much, and the vacuum pump chamber is deformed and leaking. The vacuum pump chamber should be repaired or replaced. 5. Air leakage is caused by poor oil seal on the end face of the imported vacuum pump. Remove the end cap, check for sundries or unevenness, and clean or repair it. Imported vacuum pump 2、 There is a problem with the imported vacuum pump oil. 1. The oil level of the inlet vacuum pump is too low. The center line of the oil standard shall be filled with enough oil. 2. The engine oil is polluted and deteriorated. The oil should be replaced with a new one. 3. The brand of oil does not match. Replace the vacuum pump oil of the specified brand. 4. The oil circuit is blocked and an appropriate amount of oil is not maintained in the vacuum pump chamber. Check the oil circuit and the oil inlet of the oil valve to keep the oil circuit unblocked. 3、 The inlet filter screen of the inlet vacuum pump is blocked. The filter screen shall be removed and cleaned before installation. 4、 The rotor spring of the imported vacuum pump is deformed or broken, and the rotor fails. The spring deformation shall be repaired or replaced so that the rotor product is in good contact with the rotor. Vacuum Pump Heat Treatment Guide,Heat Treatment Equipment Liquid Ring Vacuum Pump
