Is the floor heating and circulation pump useful?

In both north and south, the temperature always drops very quickly in the middle of winter. When the temperature drops, the important thing is to heat it up. Although there are many methods of heating, it can be used in many places. In fact, floor heating is a special case. Not only is the heating form good, but the price is not expensive, so is the heating and circulation pump useful?

Floor heating and circulation pump are useful. When the local heating pipe pressure is not stable or the water circulation is not good, you can install the floor heating circulation pump. It can improve the water flow velocity in the floor heating pipe, improve the heating efficiency and make the indoor temperature rise.

Circulating pump

1. As the name suggests, install a heating circulation pump on the heating system to increase the pressure of the system, increase the flow of heating hot water, and then increase the heat dissipation of the radiator to increase the indoor temperature. Circulating pumps are mainly aimed at self-heating users, or circulation of large and medium-sized home heating systems.

2. Floor heating and hot water circulation. If the inlet temperature is acceptable and the outlet temperature is low, installing a circulating pump can solve this problem, but if the inlet and backwater temperatures are low, it is also useful to install a circulating pump when the heating is not hot. Generally, the pump is installed on the backwater line, a section of pipe is removed from the original system, and the pump is connected to the pipe.

The centrifugal pump knowledge is all here!
The basic structure of the centrifugal pump is composed of six parts are impeller, pump body, pump shaft, bearing, sealing ring, packing box. 1, the impeller is the core part of the centrifugal pump, its speed is higher than the force, the blade on the impeller plays a major role, the impeller in the assembly before the static balance experiment. The inner and outer surfaces of the impeller shall be smooth to reduce the friction loss of water flow. 2, the pump body is also called the pump shell, it is the main body of the pump. Plays a supporting and fixing role, and is connected with the bearing bracket. 3, the function of the pump shaft is to connect the coupling and the motor, the torque of the motor to the impeller, so it is the main part of the transmission of mechanical energy. 4. Plain bearing uses transparent oil as lubricant and lubricates it to the oil level line. Too much oil to seep out along the pump shaft, too little bearing and overheating and burning cause accidents! During the operation of the pump, the temperature of the bearing is 85 degrees, and the general operation is about 60 degrees.

Northern winter water pump anti-freezing, thawing measures
Winter comes, the air is dry and cold, and the temperature drops to below zero. Are you worried that the water pump in use is easy to freeze or even the pump body is frozen and cracked under low temperature conditions, just like in previous years? In view of this situation, xiaobian summed up the following measures for anti-freezing water pump maintenance. 1, add insulation material for the pump to prevent the pump from freezing; (Water pumps also need to wear "clothes", exposed in the cold outdoor work, we can use cotton wool, towels, waste clothes and other clothes to wrap exposed outdoor water pumps, water pipes, faucets and other water facilities, to achieve thermal insulation effect.) 2, the pump body will not be temporarily empty, when using water, to prevent the pump freezing freezing pump: 3. The doors and Windows of the basement pump room and those without hVAC are closed. The unfinished basement pump room and wind tunnel are blocked. 4. Because all pumps of our company are delivered with hose pressure test, there is water in the pump body and management valve of the factory equipment. If the equipment is not installed, please be sure to take drainage measures to prevent freezing and cracking. 5. If the pump is frozen, do not start the pump. Use hot water or boiled water to pour into the pump to internalize the ice, or heat the pump shell.

Shanghai Municipal Bureau of Quality supervision: 6 batches of water pump products have been found unqualified
The Shanghai Municipal Bureau of Quality and Technical Supervision announced on its website on Monday the results of a random inspection of 70 batches of water pump products in 2015. After the inspection, six batches failed to pass the inspection. According to the introduction, water pump is listed in the national industrial products production license catalogue of products. There are a total of 74 certified manufacturing enterprises in Shanghai, of which 70 have actually received products this time, and another 4 have not received samples due to production suspension and other reasons. According to gb10395.8-2006 "Agricultural and forestry tractors and machinery Technical requirements part 8: Drainage and irrigation pumps and pump units" and other national standards and related standards, the following items of submersible pump products were tested: Overload protection, grounding measures, insulation resistance and electric pump leads to cable and stator winding resistance to voltage, electric pump efficiency, rated capacity at the time of the head, electric pump input power, pump shaft power, power factor, temperature rise within the limit, motor stator cavity water (gas) pressure test, the operation instruction content, sign/sign firmly, production license; The following items of centrifugal pump have been tested: specified point efficiency, specified point flow, head, NPSH, leakage, unit operation, vibration, noise, appearance quality, mark, license mark.
