This article is the continuation of previous one. PK Machinery will introduce you load testing running of scraper conveyor.Load test running 1. Once no-load test running becomes normal , please test run with load.2. After scraper conveyor runs with load normally, please feed the material uniformly to avoid blockage.
3. The casing must be fully sealed to avoid the material overflowing. A grate net must be added on the inlet to avoid massive material or hard objects enter into the scraper conveyor.
4. After material inside the scraper conveyor is discharged from the outlet completely, then stop the machine. 5. During no-load and load test running, please make a record that includes voltage, current, power and scraper chain running speed etc. and check whether they meet the requirement of design or not.
With regard to scraper conveyor, there are many types.Buried scraper conveyor belongs to it.The main features of buried scraper conveyor are that can be in a slant or vertical angle and operate together or individually.So it is universal.Buried scraper conveyor has a simple structure,light weight,small volume and good sealing.Also,it is easy to install or maintain.It not only can convey material in a horizontal angle,but also in a slant or vertical angle.What’s more, it can feed or discharge materials in many points.So its layout is very flexible.The working conditions can be changed markedly when it convey materials because the shell is enclosed.And then it can protect environment.
We can solve the problem existed in medium plate which is made from steel through using ultra high molecular weight polyethylene.Thus, we can get plastic scraper conveyor.With regard to large-scale scraper conveyor,we can apply the method of steel-plastics compounding material.Using ultra high molecular weight polyethylene as lining,it can improve the abrasion resistance of large-scale scraper conveyor,and then prolong the service life,reduce the friction coefficient and bring down power consumption. It has great significance for large-scalescraper conveyor.Because of these features,buried scraper conveyor gets much attention of enterprises.
