Why do you need to record the recharge, the water level of the pool, and calculate the water supply for each shift?
icon

In a sense, the operating parameters of the system show the operating state of the system, record the water supply and the water level of the pool in each shift, and calculate the water supply. * Can monitor whether the system is in normal state. For example, when the water meter has problems, we can find them in time, so as not to cause losses to the company. Second, monitor the operation level of the whole plant to promote water conservation.

The outlet valve of the pump can only be opened 20%. If the outlet valve is opened, there will be a surge. Why is that? How to solve it?

The outlet valve of the pump can only be opened 30%, otherwise the running current will exceed the rated current. Why is that? How to solve it?

The selection of pump deviates from the actual operating conditions too much, mainly because the pump head selection is large. Can be calculated after cutting impeller diameter to solve.

Shanghai Municipal Bureau of Quality supervision: 6 batches of water pump products have been found unqualified

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.

What are the characteristics of the floor heating circulation pump?

What are the characteristics of the floor heating circulation pump?

1. Simplify installation In the case of natural circulation, the circulating pressure of the system is due to the poor specific gravity of the water. The circulating pressure produced is usually only a few thousandths of the atmospheric pressure. Therefore, the existence of bubbles in the system will seriously hinder the realization of circulation. After using the circulating pump, heating installation is greatly simplified. 2. Arbitrary layout In the case of natural circulation, in order to ensure the circulation pressure of the system, the radiator and the cooker are separated from the necessary distance in the direction of gravity, resulting in "the radiator hanging high" or "the stove falls into the ground" and other problems. Using forced circulation, without considering the relative position of radiator and furnace. Even if the furnace is higher than the radiator, it will not affect the circulation of the system. Circulating pump 3. Optimize the system Because the power of natural circulation is very small, a very thick main pipe is usually used to reduce the resistance of the system. Even so, the system often has problems with circulation or heat dissipation. After the use of the circulating pump, the main diameter can be reduced appropriately, so as to simplify the installation, optimize the circulation, beautify the appearance. 4. Save money The disadvantage of natural circulation is the low efficiency of the radiator. Under normal conditions, the temperature difference between the top and bottom of the radiator is more than 40 degrees. The forced circulation can reduce the temperature difference between the radiator and the radiator. Based on the same heat dissipation calculation, it is estimated that the radiator can save 20-30%. In addition, each system can achieve considerable cost savings due to reduced mains power.

Is the floor heating and circulation pump useful?

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.
