How to Increase Boiler Pressure?

Оршил

There are various reasons why boiler pressure needs to be increased. Энэ нийтлэлд, we will discuss the most common reasons that boilers require additional pressure and how you can increase it.

Why is boiler pressure important?

Boiler pressure is important because it controls the amount of heat produced and lost, as well as the flow rate through your system. Бойлерийн даралт ихсэх нь илүү их уур бий болно гэсэн үг юм, Энэ нь таны үр ашгийг нэмэгдүүлж, эрчим хүчний зардлыг бууруулдаг.

Бойлерийн даралт нь ашиглалтын мөчлөг бүрт хэр их ус хэрэглэхэд нөлөөлдөг. Хэрэв танд байгаа бол өндөр даралтын уурын зуухны систем, бага даралтын системтэй харьцуулахад халаалтын мөчлөгийн үед ууршилтаас болж алдагдал бага байх болно (тухай 10% бага).

Бойлерийн бага даралтыг юу үүсгэдэг вэ?

One of the fundamental reasons for low boiler pressure is the inadequate water level within the system. This can be caused by evaporation over time or improper filling during installation or maintenance. Insufficient water levels can result in reduced heat transfer efficiency and potential overheating of components, leading to pressure drops.

Leaking Boiler

A leaking boiler can result in the loss of water from the system, causing a drop in pressure. Leaks can occur due to deteriorated components, damaged seals, эсвэл цаг хугацааны явцад зэврэлт. Эдгээр алдагдлыг анх илрүүлэхэд бага, хэцүү байж болно, систем дэх даралтыг аажмаар бууруулах.

Даралт бууруулах хавхлага гоожиж байна

Даралт бууруулах хавхлагын үүрэг нь илүүдэл даралтыг суллаж, бойлерыг хэт даралтаас урьдчилан сэргийлэх явдал юм. Гэсэн хэдий ч, буруу ажиллаж байгаа хавхлага нь тасралтгүй даралт алдагдахад хүргэдэг. Хэрэв энэ хавхлага гоожиж байвал, Энэ нь хүссэн даралтын түвшинг үр дүнтэй барьж чадахгүй байж магадгүй юм.

Бойлерийн тэжээлийн насос алдагдсан

The бойлерийн тэжээлийн насос is mainly responsible for keeping the water level in the boiler within a safe range. If this pump is leaking, it can lead to inadequate water supply and subsequently low boiler pressure. Leaks can stem from damaged components or worn-out seals.

Faulty Boiler Pressure Gauge

A malfunctioning pressure gauge can provide inaccurate readings, leading to an incorrect perception of the actual boiler pressure. This can result in unnecessary adjustments and potential pressure drops.

High Ambient Temperature

In warmer weather, the ambient temperature can affect the pressure reading in your boiler. Higher temperatures can cause the water to expand, resulting in increased pressure. Гэсэн хэдий ч, this isn’t a cause for concern as long as the pressure remains within safe limits.

What is the correct pressure for my boiler?

The pressure in your boiler is measured in pounds per square inch (psi). The more water you have and the hotter it gets, the higher the pressure will be. The correct pressure should be between 15 болон 22 PSI.

How to top up the pressure on a boiler?

Хэрэв та бойлер дахь даралтыг нэмэгдүүлэх шаардлагатай бол, эдгээр аргуудыг дагана уу:

Зөв хэмжээний ус хэрэглээрэй. Бойлерийн зорилго нь усыг халаах явдал юм, тиймээс та үүнд хангалттай байгаа эсэхийг шалгах хэрэгтэй. Хэрвээ биш бол, Дээр болон доор байгаа бөмбөлөг бүрийн хооронд тэнцүү хэмжээний зай байх цэг хүрэх хүртэл нэмж нэмнэ. Энэ нь бүх эд ангиудыг үр ашигтай ашиглаж байна гэсэн үг юм!

Бүх зүйл зөв ажиллаж байгаа эсэхийг шалгахын тулд даралт хэмжигчээ тогтмол шалгаж байгаарай. Хэрэв үгүй ​​​​бол бүх зүйл дахин сайхан болох хүртэл тохируулна уу (this might mean adding more coal or turning down some knobs).

Make sure that nothing else needs replacing before doing anything else. Such as changing out old parts or adding new ones.

Last, you need to ensure that you’re not over-pressurizing it. The best way to do this is by using a pressure relief valve.

What to do if the boiler does not repressurize?

If the boiler doesn’t repressurize, you can follow these ways. Identify the root cause of the problem and ensure your boiler is back to optimal performance.

Call a Professional

If you find that your boiler is not repressurizing despite your efforts, it’s advisable to call a professional boiler technician. They have the expertise and tools to diagnose the issue accurately and recommend the appropriate solution.

Check for Boiler Leaks

Leaks within the boiler system can result in a drop in pressure. Follow these steps to check for leaks:

a. Inspect visible components: Carefully examine the boiler and its connections for any signs of water leakage. Such as damp spots, puddles, or visible water trails.

b. Monitor pressure changes: If the pressure drops significantly shortly after repressurizing. it might indicate a hidden leak within the system.

Check the Pressure Gauge

a. Compare readings: Use a reliable pressure measuring tool to compare the reading on the boiler’s pressure gauge. If there’s a significant discrepancy, the gauge might be faulty.

b. Consider replacement: If the pressure gauge consistently shows incorrect readings, consider replacing it with a new, accurate gauge.

Ensure Proper Pressure Relief Valve Function

The pressure relief valve is essential for preventing over-pressurization. Make sure it’s working correctly:

a. Observe the valve: The pressure relief valve should release small amounts of water during operation. If water is continuously dripping from the valve, it might be malfunctioning.

b. Test the valve: Consult your boiler’s manual for instructions on how to test the pressure relief valve’s functionality. Follow the provided procedure to ensure it’s operating as intended.

FAQs.

Is low boiler pressure dangerous?

Low boiler pressure can be a concern as it might indicate leaks, system inefficiencies, or malfunctions. While not necessarily dangerous, it can lead to reduced performance and potentially cause damage if not addressed promptly.

What PSI should a boiler run at?

The recommended pressure range for most boilers is around 1 руу 1.5 bars when cold. This corresponds roughly to 15 руу 22 PSI.

Does low boiler pressure affect hot water?

Yes, low boiler pressure can affect the hot water supply. In some cases, it might lead to reduced hot water output or inconsistent water temperature.

Can I increase the boiler pressure when hot?

It’s generally not recommended to adjust the boiler pressure when the system is hot. Boiler pressure adjustments should be made when the system is cold to ensure accurate readings and safe operation.

Can I fix the boiler pressure myself?

Minor adjustments to boiler pressure can be done by homeowners, but more complex issues should be addressed by a professional boiler technician to ensure safety and proper diagnosis.

What should boiler pressure be when the heating is off?

When the heating system is off, the pressure gauge is typically around 1 руу 1.5 bars (15 руу 22 PSI), but exact values may vary depending on the specific boiler model and manufacturer.

Дүгнэлт

With a little bit of knowledge and the right tools, you can increase boiler pressure easily. It’s important to understand that not all boilers require the same amount of pressure.
