Condensor Rubber Ball Cleaning Water Treatment Equipment

1.Introduction

Condenser rubber ball cleaning device(Hereinafter referred to as the cleaning device) is a kind of physical methods to scrub central air conditioner on condenser the inner wall of the tubes equipment. Central air-conditioning in the process of refrigeration, The refrigerant temperature escalate, must be cooling the refrigerant. A cooling water system is to coolthe refrigerant piping system, Condenser is heat exchange device for cooling the refrigerant. cooling water enter intoCondenser flowing through the heat exchange inner tubes to out. the cooling system flows through the heat exchangeout wall tubes, through the condenser tubes to transfer heat, thus play a role in cooling the refrigerant. Low temperature of cooling water flowing into the condenser and heat exchange cooling system then outflow in high temperature, after a long operation will have a scale in the exchange heat tubes wall, stains precipitation, affect heat transfer efficiency,  refrigerant cooling will affect the cooling effect, will increases the central air conditioner mainframe load, reduce the the  central air conditioner mainframe life, So will need regular cleaning on the condenser heat exchange inner wall of tubes, thus extending the life of the central air conditioning mainframe.

Scale will not only decrease the heat transfer efficiency, but also increase the water resistance. Prone to corrosion, shorten product life, increase costs. According to the specific working condition, it may have different impact on the cooling system. But for each system are in a state of dynamic equilibrium.

On-line rubber ball cleaning system is a kind of device,which clean inside wall of the condenser tubes by injection and recollect ball. Once the system is installed, you can reduce the cost of water treatment chemicals.

2.During the actual operation of the cooling water system, there are several kind of wall pollution situations:

1. Scale,hard scale fouling layer, when the condenser temperature is high, and water hardness is high, it's likely to happen. Conventional water treatment agent is capable of solving this kind of problem.

2. Microorganisms or fungi or algae organic film deposited on the pipe wall, is a kind of loose viscous material, have a greater thermal resistance of the heat exchanger hazard.

3. Impurities and particles,as there is a certain thickness of the laminar layer, the flow rate is small, particularly a mixture of particles and organic adhesions will form into a more stable dirt.

4. Corrosion, acid dissolved in water is the main reason for corrosion, if carbonate ions corrosive ions coexist with other sources, it will enlarge the resistance, thereby shorten the life of the equipment and pipe systems.

3.Automatic Cleaning Function

1.solve the condenser corrosion and scaling problems

2.optimize heat exchange efficiency

3.Maintain the cleanness of the condenser tubes

4.No need manual cleaningWorking Principle

4.Characteristics
1.Automatic: microprocessor controlled programmable controller is responsible for the overall operation of the condenser line cleaning system,no need worker.
2.Reliable: the injection valve and drain valves are the only two moving parts, thus enhancing the reliability of the condenser line cleaning system.
3.Free of maintenance: Because only two valve is movable, no need maintenance. This reduces operating costs, and the release of insufficient maintenance staff for other critical maintenance work.
4.low operation costs: the sponge balls are the only consume materials.It must be replaced every five months. For 500 tons central air-conditioner, the annual fee is only $ 80.

5.Advantage
1. A simple and reliable online cleaning device, with no downtime, can provide long-term thorough and effective cleaning.
2. Automatic control, can set their own cleaning frequency and time.
3. Keep the condenser heat exchanger in the best state, improve the overall efficiency of the unit, reducing operating costs.
4. Reduce central air-conditioning maintenance costs, reduce the use of chemicals, reducing the condenser tubes corrosion.
5. Central air-conditioning compressor to prevent overload of work, extend the service life of the unit.
6. Saving central air-conditioning maintenance downtime on the type of production unit is very favorable.
7. Rubber ball using long period, rubber ball circulation only within the pipeline to avoid damage to the pump on rubber ball.
8. Small size, simple operation, easy installation.

9.Condenser Rubber Ball Cleaning Device-Characteristic- Principle

1. Ball injector: Put the rubber ball into the tee, closing electric valve 3, 4, opening electric valve 1, 2, when open the max position, opening pump1( ball injector pump), Flow switch is sended by signal, pump 1 go on working, rubber ball in the ball injector follow the water flow into the condenser entrance together, rubber ball under the the cooling water pressure, crush into the exchange heat pipe, washing the inner wall, come out the exchange heat pipe then into the ball injector which is stopped by net, cooling water through the mesh into the cooling water system piping continue recycling, at this point, ball injector cleaning end.

2. Ball collector: Close the electric valve 1, 2, stop pump 1(ball injector pump), open the electric valve 3, 4, when open the max position, opening pump 2 ( ball collector pump), Flow switch is sended by signal, pump 2 go on working, rubber ball in the ball collector follow the water flow into the ball injector together, rubber ball is blocked by net, water get back into the cooling water system piping, After collect all rubber ball then closed 3, 4 electric valve, stop pump 2(ball collector pump) At this point, ball collector cleaning end.

Aboving two parts of ball injector and collector get together as a rubber ball cleaning process, can be set by the total time to cleaning in many times.
