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 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.

The centrifugal pump knowledge is all here!

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

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.

Fire pump manufacturers: to introduce you how to buy fire pump

Fire pump manufacturers: to introduce you how to buy fire pump

Fire pump is divided into vertical fire pump and horizontal fire pump, the flow of liquid is one of the important performance data of the choice of fire pump. The flow of conveying liquid is directly related to the production capacity of the whole device, so the choice of fire pump above, pay attention to the flow of fire pump, the size of the flow will affect the efficiency of the fire pump. When buying fire pump flow and head is an important standard, the second advantage of fire pump lies in its attention to energy saving and environmental protection. Because water is a valuable resource, the pump can save water under the premise of its good performance and humanity. When buying a fire pump, a very important point is the choice of model. The fire pump should be selected according to the height of the floor and the water flow required in the room. According to the power, speed, etc., choose the right head, and strict control of quality, in line with the national quality inspection standards.

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.
