The equipment does not cause resonance when running; in view of the sound insulation, equipment other than the heat collector must be placed in a proper place (place with maintenance, distance from the wall, etc.) as specified, and the specific installation form is shown.

Before equipment is installed, the foundation is firstly encountered in the engineering construction of a solar water heating system, is the basis of the most basic and most important layout in the later construction, and comprises a cement foundation and a hanging part of a heat collector steel bracket and a heat storage water tank. The solar base adopts a concrete foundation, and a square foundation is made on the roof to ensure the integrity of a roof waterproof layer, and the embedded steel plate is reliably connected with the steel bars in the foundation. Before the heat collector is installed, positioning and positioning axes are the most important links in construction, and the positioning axes strictly follow the positioning axis dimension requirement of an engineering plan and are strictly controlled to be accurate.

Specific mounting details are shown.

Details to be noted in the specific installation of solar water heating systems

The solar water heating system is mainly divided into four parts, namely heat collector, pipeline and equipment and heat preservation installation.

The installation angle of the heat collector is local latitude plus or minus 10 degrees, the installation error is controlled within plus or minus 10 degrees, the installation is firm, and the connection mode meets the design requirement. The angle steel is welded on the bracket for fixing, and the rows of heat collectors are on the same plane. The main point of the heat collector installation connection is that the coaxiality of the butt joint of the headers is ensured on the arranged bracket. The purpose is to ensure the straightness in the axial direction from the first header pipe orifice to the last header pipe orifice, thereby ensuring the normal operation of the system. Its installation allows a value of < 2 mm. The wind-proof treatment after the heat collector is installed in place, each heat collector should be firmly connected with the bracket by using screws or pressing plate steel. And the steel bracket is firmly connected with the roof fixing object.

The pipeline installation is carried out according to a system diagram or an axonometric diagram, and the dimension is difficult to be standardized on the diagram due to component errors and structural errors, so that a certain flexibility is provided for pipeline construction. The distance between the pipes is actually measured, the first key point of installing the pipeline is that the blanking is required to be matched with the positions of the two pairs of interfaces to achieve the purpose of smooth running of the system, and the 'downhill phenomenon' of the pipeline system is ensured not to occur. The pipe support bracket in the solar water heating system is generally arranged for fixing rather than bearing. Mainly prevents the pipeline from bending to cause a reverse slope phenomenon and prevents circulation.

The support hanger arrangement should follow the following principle:

the supporting hanger is supported on a reliable structure; the spacing is reasonable, and too thin spacing can not prevent the pipeline from bending;

the structural form is to be ensured to be used, the aim is simple, and the construction is convenient; the cantilever type supporting hanger is not too long, and a diagonal bracing is arranged below the cantilever type supporting hanger; accessories such as a water pump, an electromagnetic valve and the like are provided with reliable supporting and hanging frames at the pipe inlet and outlet so as to reduce vibration to a pipeline;

the supporting hanging frame is carried out simultaneously during the construction of the pipeline.

The installation of the pipeline, particularly the indoor pipeline, cannot be carried out synchronously with the construction of the civil engineering main structure engineering, so that the construction of the reserved holes and the embedded parts is carried out by matching with the civil engineering before the pipeline is installed. The holes to be reserved for pipeline installation mainly comprise through-wall holes and floor holes, and the embedded parts before pipeline installation comprise embedded parts of pipeline brackets and embedded waterproof sleeves for pipelines penetrating through floors. The specification, shape, manufacture, pre-embedding and the like of the embedded part of the pipeline bracket should be constructed according to the design or specification; the horizontal pipeline of the system is installed along water and lifted, and the gradient is not less than 3 per mill, so that the exhaust is facilitated. The valve, water pump and other parts of the system pipeline need to be replaced are provided with movable interfaces so as to be convenient to disassemble, maintain and replace. The pipeline system (indoor and outdoor) needs to be insulated.

The sequence of field installation is: a vertical pipe and a branch pipe. During the installation process, care should be taken that: when the vertical pipe is installed, the vertical pipe passes through the pipe hole from the top to the bottom layer hanging wire so as to correct the inclined hole and pop up the pipe bit line. The sleeve pipe should be arranged at the position of the riser penetrating the floor slab, and the pipe clamp should be installed according to the position line of the riser before the riser is installed. In the installation process, plumb hanging wires can be used for checking the verticality of the vertical pipe, so that the vertical pipe meets the standard requirements. The joint of each through-wall pipeline cannot be positioned in the wall and is 3 cm to 5cm away from the wall surface; in order to prevent the construction process sundries from falling into the pipeline to cause blockage, each open pipe is sealed in time.

The water tank is installed, 1, the wall body can bear twice the weight of the water heater filled with water, and the fixing piece is firmly installed; 2 is to ensure that the water heater has maintenance space. The water inlet of the water heater (blue blocking cap) is connected with a pressure release valve, and the hot water pipe is connected with the water outlet (red blocking cap). The raw material belt is used at the joint of the pipeline to prevent water leakage, and the safety valve cannot be screwed too tightly to prevent damage. After all the pipes are connected, the water tap or the valve is opened, then the hot water is opened to fill the water heater, and the air is discharged until the water tap flows out, so that the water is filled. And closing the hot water tap, and checking whether water leaks at all the joints. If water leakage exists, the water tank is emptied, the water leakage joint is repaired, and then the water heater is filled with water again.

The water pump is installed, the weight of the pipeline is not born on the water pump during installation, and the water pump is easy to damage; the foundation bolts must be screwed down, so that the performance of the pump is prevented from being affected by vibration during starting, and a damping pad is additionally arranged on the base; before and after the pump is installed, the following three points should be noted, 1. Carefully checking whether hard objects affecting the operation of the water pump exist in the pump flow channel, avoiding affecting the water pump components; 2. checking rotor parts of the water pump, wherein friction sound or blocking phenomenon is avoided, otherwise, the pump is disassembled for checking reasons; 3. the water pump is required to be tested after wiring, the test operation is electrified for 2 seconds, and whether the steering of the impeller of the water pump is normal or not is checked; for convenient maintenance and safe use, a filter, a regulating valve and a pressure gauge are arranged on an inlet pipeline of the pump;

because the solar glass tube heat collector is positioned on the roof, corresponding lightning protection grounding work is needed to be performed as shown in the figure, and the danger is avoided.

The heat preservation of solar water heating engineering is of vital importance, and the aim is to reduce heat energy loss as much as possible. The heat energy loss between the heat collector and the heat collector, between the water pipeline and the heat storage water tank and between the water pipeline and the heat storage water tank are all energy consumption points, and the heat energy loss of the points is quite large. In order to reduce the heat energy loss, strict insulation is necessary in these places. The heat dissipation capacity of the insulated pipe is only about 15% of that of the bare pipe. That is to say, the heat loss after heat preservation treatment can be reduced by 80-90%, and a large amount of heat energy is saved.
