With the help of the principle of vacuuming, the suction truck is able to provide daily cleaning services. With the extension of the use time, such machines will also encounter breakdowns. So, how do we troubleshoot the problem of the vacuum pump of the suction truck in daily use?
First of all, we need to check whether the valve of the suction truck vacuum pump is open. If we don't open the outlet in the process of use, it may cause garbage to clog in the machine and cause the machine to malfunction.
The second part is to see if the mouth of the suction pipe of the suction truck and the position of the filter are blocked by foreign matter. If the suction nozzle is blocked by a foreign object, it may cause the machine not to operate normally and eventually cause an internal failure.
The third step is to check if there is a leak in the suction truck . Because the normal operation of such machines is mainly due to the vacuum state formed by its pressure to move, once the machine leaks, then the machine will not be able to run properly, the correct way is to find the location of damage, and timely maintenance.
The fourth step in the investigation work is on the speed of the suction truck. In order to be able to suck items, the rotational speed of the machine must meet certain requirements, otherwise it will affect its degree of vacuum and may cause malfunctions. Under normal circumstances, the normal suction truck vacuum pump is 1500 rpm.
During the investigation, we must avoid the fact that the machine does a vacant movement of the vacuum pump for a long time, which will cause its temperature to be too high, which may burn out the sliding plate of the vacuum pump and ultimately affect its life.
The suction pump vacuum pump is the main engine for the operation of the machine, so its quality and failure problems are the main areas that need to be solved. While safeguarding quality, we also need to regularly troubleshoot its failures. This will not only ensure the operation of the machine, but also protect the life of the machine.
Titanium Dioxide(TIO2)
Titanium dioxide is an important inorganic chemical pigment, the main component is titanium dioxide. The production process of titanium dioxide has two process routes: sulfuric acid method and chloride method. It has important applications in coatings, inks, papermaking, plastics and rubber, chemical fiber, ceramics and other industries.
It has two types: rutile type (Rutile R type) and anatase type (Anatase A type). The rutile crystal structure is compact, relatively stable, and has low optical activity, so it has good weather resistance, and has high hiding power and decolorizing power.
Titanium dioxide is widely used in coatings, plastics, rubber, ink, paper, chemical fiber, ceramics, daily chemicals, medicine, food and other industries.
The coating industry is the largest user of titanium dioxide, especially Rutile Titanium Dioxide, most of which is consumed by the coating industry. The paint made of titanium dioxide has bright colors, high hiding power, strong tinting power, low dosage, and many varieties. It can protect the stability of the medium, and can enhance the mechanical strength and adhesion of the paint film to prevent cracks. Prevent the penetration of ultraviolet rays and moisture, and extend the life of the paint film.
The plastics industry is the second largest user. Adding titanium dioxide to plastics can improve the heat resistance, light resistance, and weather resistance of plastic products, improve the physical and chemical properties of plastic products, enhance the mechanical strength of the products, and extend the service life.
The paper industry is the third largest user of titanium dioxide. As a paper filler, it is mainly used in high-grade paper and thin paper. Adding titanium dioxide to the paper can make the paper have better whiteness, good gloss, high strength, thin and smooth, no penetration during printing, and light weight. Titanium dioxide for papermaking generally uses Anatase Titanium Dioxide without surface treatment, which can act as a fluorescent whitening agent and increase the whiteness of paper. However, laminated paper requires the use of surface-treated rutile titanium dioxide to meet the requirements of light resistance and heat resistance.
Titanium dioxide is also an indispensable white pigment in advanced inks. The ink containing titanium dioxide is durable and does not change color, has good surface wettability and is easy to disperse. The titanium dioxide used in the ink industry has rutile type and anatase type.
The textile and chemical fiber industry is another important application field of titanium dioxide. Titanium dioxide for chemical fiber is mainly used as a matting agent. Since the anatase type is softer than the gold red type, the anatase type is generally used. Titanium dioxide for chemical fiber generally does not require surface treatment, but in order to reduce the photochemical effect of titanium dioxide and prevent the fiber from degrading under the action of titanium dioxide photocatalysis, surface treatment is required for some special varieties.
The enamel industry is an important application field of titanium dioxide. The enamel grade titanium dioxide has high purity, good whiteness, fresh color, uniform particle size, strong refractive index and high color reducing power, and has strong turbidity and Opacity, make the coating thin, smooth and strong acid resistance after enamelling. It can be evenly mixed with other materials in the enamel manufacturing process, does not agglomerate, and is easy to melt.
The ceramic industry is also an important application field of titanium dioxide. Ceramic grade titanium dioxide has high purity, uniform particle size, high refractive index, excellent high temperature resistance, and does not change ash at 1200°C for 1 hour. High opacity, thin coating, light weight, widely used in ceramics, construction, decoration and other materials.
