How to install the radiator installation precautions

With the improvement of people's living standards, winter has become less cold, many families will choose to buy radiators, radiator installation is the most important part of the consumer before using the radiator, because the quality of the radiator installation is not only good Affect the normal use of radiators, but also lead to leakage of radiators, radiators and other hot issues, the main reason, then how to install the radiator ? Let's learn about it together.

[What is a radiator]

Heating radiators, also known as heating radiators, are one of the best methods for heating in winter. Because the water pressure of heating systems is generally more than 0.4 MPa, if they are not installed properly, they will suffer heavy losses when they are leaked. Therefore, the radiators are installed and heated. The quality of the film is as important. Considering the appearance of installation and ensuring safety, the installation of the radiator should follow the steps below.

[How to install the radiator]

The first step is to conduct on-site measurement and design together with the technicians of the radiator vendors to determine the type, number, inlet and outlet modes and specific installation positions of the radiators. The technicians shall communicate with the owners according to the actual situation to determine the radiators. Model, number of groups, number of pieces per group, installation location, etc., and signing a purchase and sales contract with the seller;

The second step: sign the construction agreement with the radiator construction unit to ensure construction quality and risk. The general construction unit must indicate on the construction agreement that the construction of the heating system must guarantee at least one heating season. If the radiator sales units and construction units are the same unit, the best.

The third step: the construction of the first phase of the radiator installation. The installation of the radiator is divided into two steps: the first phase and the second phase. The first phase of heating includes positioning of heating equipment, grooving, piping (or rerouting), pipe connection (weld pipe), installation of manifolds, and pressure testing; the second phase includes: installation of radiators (radiators) The fixed suspension, the connection of the valve to the radiator and the heating pipe), the entire system pressure detection and the adjustment of the radiator.

Note: The construction of the first phase of the heating is performed after the renovation of the wall, before or after the construction of the hydropower and before the construction of other renovation procedures. After the first phase of the heating project has not been completed and signed and approved by the owner, other decoration processes must not be allowed to proceed.

It needs to be emphasized that, for aesthetic reasons, if the heating installation is carried out before the renovation, the branch pipes connecting the heating supervisor and the radiator must be buried under the floor and in the wall, and only the temperature control valve can be seen when connecting with the radiator. There are now many heating construction workers in order to save time, branch pipes directly from the ground leakage and the radiator is connected to the ground, so each group of radiators have two pipes leaking outside, not only beautiful and easy to break.

[Radiator installation location selection note]

1, when the heating starts to give the radiator deflated, so as to ensure the heat dissipation.

2. The radiator should be installed under the window so as to prevent the unpleasant feeling caused by the cold wind of the window and contaminate the wall surface.

3, the full year of water maintenance, any material radiator water maintenance is an effective means of anti-corrosion.

4, can not add a radiator package, one radiator filth, and second, affect the cooling effect.

5, to avoid use in a humid environment. Radiators use boilers to produce steam or hot water, and they are transported through pipes to radiators (commonly known as radiators) in buildings to radiate heat or convection to increase the room temperature.

Summary: The above is an introduction to how to install heating in Xiaobian. I hope to help everyone.

Angular Contact Ball Bearing

Angular contact ball bearings mainly bear large unidirectional axial load. The greater the contact angle, the greater the load bearing capacity. The material of cage is steel plate, brass or engineering plastics. The forming method is stamping or turning. It is selected according to the bearing form or using condition. Others include combined angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.

Angular contact bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient. Retainers are made of brass, synthetic resins or others subject according to individual bearing features and application conditions.

Angular contact ball bearing include:

1) Single row angular contact ball bearing

2) Matched angular contact ball bearing

3) Double row angular contact ball bearing
