The packages have two functions of producing heating spa and consumption spa. The pump package is one of the most important components of the wall package, and its repair is expensive, and some pump models cannot be repaired, and it is considered one of the most expensive components of the package. Pumps have been produced and marketed under different titles such as Dob, Granfus, Willow, etc.
Wallpaper pump
The wall cage is a heating system that can be used to heat water and can also be used in a radiator or heater. When hot water flows through a heater or radiator, it heats the air around it. The flow of hot water in the heater is done by the package pump. The pump is one of the most expensive components of a package and its price is at least one million seven hundred thousand tomans according to the pump model used. The package pump is considered one of the most important parts of the package, when it is damaged, the hot water flow in the heater will not be done. The package pump is under a lot of pressure when the water is flowing, and these pressures cause it to be damaged. In some pump models, it can be repaired, but for the repair, skilled people should be used in package repairs, because they have skills and do not damage other components of the package during repair. Repairs and even replacement of this part of the package are costly and care should be taken not to use the package when the pump breaks down.
The reasons for the pump pump breakage
Package pump failure has many reasons, such as the pump model installed in the package, the type of pump used in the package, the way the package is installed and operated, and the improper use of the package, which causes the failure of this important part. The main reasons such as the pump package working without water, installing the package without the magnetic filter of the heating circuit and without using the strainers of the heating return system, which causes the collection of impurities and some metal shavings in the pump, and other reasons and factors This will damage the package pump. Experts and people with experience in repairing heating systems recommend to users and customers that in addition to the correct installation and operation of the package, they should also observe some points in the use of this device in order to avoid damage to the package and its parts, such as the package pump and booster pump and pay less for repair or replacement of package parts.
The internal function of the package pump
In the single converter package, the pump works only in the heating mode, and by rotating the rotor inside the pump, it sucks the water from the heating system from the return path of the radiators and sends it to the outgoing part of the radiators
In the package When the hot water heater is in use, the pump circulates the water in the heating circuit between the main heat exchanger and the secondary heat exchanger to inductively heat the hot water heater, and in the heating mode, by rotating the rotor inside the water pump, the water from the heating system is returned from the radiators. It sucks and sends it to the left part of the radiators
Important Tips on Package Pump maintenance
- When the package pump is not working, in order to determine that the pump is faulty, it does not send electricity to the pump with the main board, by connecting the pump directly to the electricity with a cable, if the pump rotor starts to rotate, the pump healthy and the main board is broken
- the installation location of the pump is located in the return block
- in order to overcome the resistance (pressure drop) of the piping path of the heating circuit of the radiators and the plate converter of a circulating pump (circulation) in A closed circuit is used.
- When installing the package in the return path at the pump inlet, be sure to use a strainer, after installing the package, the heating path should be washed and cleaned so that it is free of any shavings and foreign waste.
- Before starting the device, make sure that the pump is not jammed. In this way, open the front cover of the pump with a wrench and then turn the pump axis to the right and left with a wrench to get it out of gear mode. br>
