Reciprocating compressor

2012-02-10View Original

Thread Content

It is a high-pressure reciprocating compressor with two-stage compression; the mass flow rate for the second stage is between 2000 and 5000 N㎡/h. I would like to know how it is possible to make use of this excess flow, or if it is possible to reduce it

This compressor is like using a large horse to pull a small cart – it increases the load on the device, and by doing so the required amount can be reduced, allowing that amount to be utilized

1. Reduce import pressure; 2. Increase processing capacity ; 3. Reduce compressor load.

This indicates that the compressor flow is excessive; the intake valve can be adjusted continuously to reduce the compressor load.

If the amount of 2-to-1 is reduced, it is necessary to increase the amounts of 1-to-1 and 2-to-2 in order to maintain the exhaust temperature. Is the ratio of two to one quite high now? What is the pressure in the compressor inlet buffer tank?

Variable speed control is the best option, haha; it’s still the most reliable choice

Will variable speed have an impact on the exhaust temperature?

Whether it’s one return for one compression stroke, two returns for two compression strokes, or two returns for one compression stroke, it is primarily used to adjust the compression ratio; adjusting the exhaust temperature is a secondary purpose… That’s my opinion…

Is the machine in question driven by an electric motor? If so, considering adding a clearance or using a Holzmeier intake valve adjustment device might be advisable. If it is driven by an internal combustion engine, then methods related to rotational speed and bypass systems could be considered, as using a bypass system with an electric motor drive does not result in cost savings.

First, it is necessary to understand the function of the compressor circuit before considering whether it can be utilized or reduced. 1. In any case, the function of the \"1-to-1\", \"2-to-2\", or \"2-to-1\" circuits is merely to send back to the inlet pipeline the gas that has been \"over-compressed\" and \"produced in larger quantities\" by the compressor (and the standard for determining this \"larger quantity\" is, of course, the gas flow rate in the system). Of course, if your factory has enough funds, you can choose not to set up a circuit and simply vent the gas produced through excessive compression directly, without using it. That’s also an option. (I don’t think any factory would waste money in this way.) In fact, the function of these circuits is the same as that of venting; it’s just a shame to vent compressed gas, so it’s sent back to the compressor inlet. 2. Generally, the displacement of a compressor is fixed at the time of manufacturing and does not change. You can adjust the amount of air delivered by the compressor to the system through a bypass. (It’s like a pump: each time the pull rod is used to compress the air, the amount of air that is expelled is fixed at the time the pump is manufactured and cannot be changed. If you need a smaller amount of air, you can make a hole in the rubber tube through which air flows out of the pump, thereby releasing the excess air – this is what is meant by a bypass circuit.) 3. As for what was said on floor #8 regarding whether a bypass circuit can change the compression ratio, the answer is yes. Because when the circuit is opened, the back pressure on the compressor definitely decreases, and thus the compression ratio of the compressor also drops. 4. Because the circuit returns the compressed gas to the inlet, the compressed gas expands again, resulting in a loss of a lot of energy. So, fine-tuning is generally done through feedback loops; large-scale adjustments are not made, as that would consume too much energy. Using residuals and reducing loop flow only increases the usage of your system.
