When most people know a product, they only pay more attention to its use, function and other use knowledge, but in fact, its production process and material also need our attention, because these are important factors affecting its work efficiency. So let's learn about the sand blasting process of a water ring vacuum pump.
1. After the first sand spray of water ring vacuum pump and natural air drying, continue to apply industrial glue (silicon dissolving slurry) on the surface of wax mold, and spray two layers of sand. The particle size of the two layers of sand is larger and coarser than that of the previous one. After spraying the second layer of sand, the wax mold is allowed to air dry under the set constant temperature.
2. After the secondary sand of the equipment is sprayed and air dried naturally, carry out three sand blasting, four sand blasting, five sand blasting and other processes successively. Requirement:
(1) According to the surface requirements, volume and weight of water ring vacuum pump, adjust the blasting times accordingly. Generally, the number of sandblasting is 3-7.
(2) The sand size of each sand blasting is different. Generally, the sand in the later process is coarser than that in the previous process, and the time of air drying is different. Generally, the production cycle of sand on a complete wax mold is about 3-4 days.
The above is the detailed operation method of sand blasting process of water ring vacuum pump. This sand blasting process actually refers to the process of cleaning and roughening the substrate surface by using the impact of high-speed sand flow. It can improve the cleanliness, roughness and mechanical properties of the workpiece surface, so that its use effect and service life can be well performed.
