Many municipal sprinkler drivers are always advised by those technicians to do an advanced maintenance of the engine during maintenance. The reason is that this is good for the engine. But when you think about it back, though the sprinkler engine will produce some metal debris or impurities during operation, the oil filter has a filtering effect. It is not assured, and some conventional maintenance can also be done in advance, so that it can be avoided. Worried about sprinkler engine wear.
Waterspray engine deepening maintenance of such items can be done, but not too frequent. In order to benefit drivers more often than not, it is not necessary. For some sprinklers with more mileages, a deeper level of maintenance can be done according to the condition of the vehicle, mainly cleaning and cleaning the nozzles and the gas junctions.
Although the instructions for each car will provide some maintenance guidance, but the oil is still the most important part of our concern, machine filter, transmission oil, brake pads these key parts. We can replace the air filter by ourselves. A considerable portion of the air filters of the sprinkler can be purchased online or at the store. It is not too much trouble to replace it yourself. But be sure to buy quality assured.
Although the sprinkler truck instruction manual has the mileage and time to replace the air filter element, it is not necessary to replace it every time. We can look at whether the air or air conditioning filter element can be used after being blown with high-pressure air. If it can, you can Delaying the replacement of the air filter is not a hassle and can be seen at a glance. Although not too expensive, the number of replacements is frequent and it is also a significant expense.
Such parts as sprinkler tires, batteries, etc., if the insurance has a damage, even if you buy a suitable at the tire store and battery store. Not only is the price of accessories higher, but the replacement of new tires and batteries will also require you to pay for your labor costs. This is unnecessary expenditure. Normally, the market price of an ordinary maintenance-free 60-ampere battery is about 300-400 yuan. The 4S quotation is not only higher, but also the hourly fee. This is not necessary.
At present, some models have the habit of using diesel fuel additives. For example, some models of sprinklers do not need to be purchased at service stations. The formal online stores provide large-brand gasoline additives to meet our needs for clean gasoline. Now the effect of some big brands of oil additives on the official website is the same. How to save money and save time, in fact, you can start small things and it is not very troublesome. (Wen/Jun Xun)
The terminal amino group of Nylon 6 slice refers to the content of -NH3 group in the macromolecular chain. The number-average molecular weight of the slice can be calculated by the content of the terminal amino group, and the method of blocking the terminal group of the polymer, the antioxidant capacity and the speed of dyeing can be speculated.
The amino group content of Nylon 6 Chips is generally controlled at about 40. The higher the content, the higher the dyeing rate of the spun Nylon 6 Yarn, the faster the dyeing, and the deeper the dyeing color. The amino acid content of the nylon 6 slices used for spinning should be controlled at a high level, but too high is not good for the uniformity of dyeing. It is more beneficial to control the low content of terminal amino groups in shallow colors.
The amino-terminal content of nylon 6 slices should be determined according to the requirements of customers. Only a few companies such as Haiyang Technology are able to provide customized services in the market. More importantly, the amino-terminal content of Haiyang Qiuxue nylon 6 slices The content is stable, which is critical for the uniformity of spinning and dyeing of silk sources.
