Discussion on the preparation of various types of compressors

Editor's note: In the process of using compressors, in order to achieve the purpose of normal and high-efficiency production, most of the time, we give more choices and maintenance to the host and spare parts, but often ignore the safety Wait for some details of the situation to understand and grasp. It should be noted that the destruction of the Qianli Dike in the ant nest seems to be a small problem. If carelessness is not paid, it will not only cause unnecessary waste, but even lead to a major accident one day. Therefore, in the compressor operation process, regardless of the size of the problem, it is necessary to pay attention and thoroughly understand and solve it. This is the prerequisite to ensure that the compressor can maintain safe and effective operation.

Then, based on the opinions of enterprises and users on spare compressors of various compressor models and related issues in the production process, we initiated a solicitation of opinions and discussions among industry insiders for the purpose of mutual agreement and mutual benefit. In this issue of the forum, let’s listen to the heated discussion among netizens.

With extensive participation and sincere communication, many difficulties and problems will be solved. This is the power of the network. Welcome to okmarts.com/news:

ID: Oliver Regarding the three compressors of piston type, centrifugal type and screw type, it is said that in operation, the piston type must consider the spare machine, because it has many vulnerable parts, maintenance is necessary from time to time, and the interval of overhaul is short, while the screw type is There is no need to consider the spare machine, nor does the centrifugal type, is that right? Help others to make a model selection consultation, and ask all experienced teachers.

I personally feel that centrifuges usually do not need to be prepared, screw machines must be prepared, imported pistons do not have to be prepared, but domestic piston machines must be prepared.

　This is the case. Generally, centrifuges in foreign countries do not need to be prepared. But this configuration is related, such as the configuration of dual oil filters, the intake filter of the filter element can be replaced without stopping the machine, and so on. General customers in China will still consider preparing the machine. The screw machine must have a spare machine, and the piston should also be considered for spare machine!

ID: wangyongchao　 I don’t understand why a screw machine must have a spare machine? ID: jamesjp The following is the following quoted speech: Yes, in foreign countries, centrifuges generally do not need to be prepared. But this configuration is related, such as the configuration of dual oil filters, the intake filter of the filter element can be replaced without stopping the machine, and so on. General customers in China will still consider preparing the machine. The screw machine must have a spare machine, and the piston should also be considered for spare machine!

This also depends on the situation. If it runs for more than 8000 hours per year, it will have to prepare the machine.

ID: wangyongchao

In fact, it depends on the process conditions. The screw machine we are using has been in operation for 7 years (in the meantime, there is no ongoing or overhaul). The machine is not equipped and has no impact on process production! In addition, even if it is an imported piston compressor, you should consider using a spare unit, otherwise it will not be fun.

ID: Oliver　 screw machine must have a spare machine? Is there any basis for this statement? As far as I know, Howden's screw compressors are not considered for domestic sales (I have a specific sales list), indicating that I am not a childcare, and I am providing model consultation to a user.

I don't think it has much to do with the compressor, it mainly depends on your usage. If the process requirements are very strict and the supply of air is not allowed to be interrupted, a standby machine must be provided. If it's just for ordinary use, it can be done without a backup machine. Just imagine, who can guarantee that your compressor never fails? !

ID: justin　 um, it is true, I think the man upstairs makes sense!

ID: hxnj The two 4L-20/8 type air compressors produced by a domestic factory in our unit are standby for each other, and the working conditions are OK! Each unit works continuously for 11 hours a day per year, which means that the low-pressure asbestos pads have to be replaced every six months (death, sinking).

ID: q123456

Haha, upstairs, the asbestos pads are selected, and I promise not to change them for a few years.　 The problem of preparing the machine should really be determined according to the actual production. If it is continuous mass production, or the direct loss caused by equipment shutdown is very large (such as glass furnace, steelmaking furnace), or the indirect loss is huge (such as loss of orders, It is necessary to consider a certain amount of spare allowance, such as huge compensation for delay in construction period), or the expected increase in demand in the future. Our unit currently has 15 air compressors with a design capacity of approximately 65,000 cubic meters per hour. It is expected that the user consumption will continue to increase during the expansion in the previous years, so a reserve margin of about 9,000 cubic meters per hour is reserved. Users continue to produce. At the peak of the current consumption, there is only a spare margin of less than 3000 cubic meters per hour. Normal maintenance and repair arrangements for the equipment are very difficult, and the application for the purchase of air compressors has been delayed. It is estimated that the approval will be waiting When we come down, we don't even have the final spare margin. If it affects user production, the loss can be too great.

ID: Justin　　 uses so much gas, running and leaking must not be ignored and avoided!

ID: What kind of air compressor lg uses depends on the working conditions. Nowadays, many users use air 24 hours a day. If there is no standby machine, it will be enough.

ID: Dongzi screw machines generally need to have a spare machine, because the piston machine is relatively familiar to users, and they can repair it by themselves regardless of the size of the problem, but the screw machine is different. In case of a problem with the main engine, the user will solve it. No, so you have to have a machine.

　ID: liyh

It takes a lot of cost to prepare the machine. If there are more compressors in the unit, you can consider spare one or several. If you only need one in total, you have to prepare one, then it is not economical! Especially imported compressors! Therefore, it is recommended to consider buying a better performance, no need to prepare the machine.

ID: hjhcompressor 　 does not prepare the machine, the key is to see the actual use of the user, whether continuous production can not be stopped, whether there is a new development plan, whether there is better profit, etc., it is a comprehensive choice, not a brand Compressor. Personal suggestion: If the company has a certain scale and good performance, it should be an imported unit and a domestically-made unit.

　ID: drunk as mud. Many users require the supplier to have a spare machine. Once his machine fails, the supplier's spare machine is required to supply air in a few hours.

　ID: lg　 good idea, but is this possible? Even if it’s like a mobile phone, a backup device is provided for free. Doesn’t it take time to install?
