●移交时：1. 高低压的正常值是几公斤，高低压控制器的设定值是几公斤，进行电流是几安，设定保护值是几安，均要记录。

2. 机台维修前请参考以上的正常值，维修前要清洗干净外观和油渍的位置，便于电工机修工维修人员的操作。

3. 空气开关不可以随意换大的，以免烧毁压缩机。

维修保养  Maintenance

保养定为三个月清洗冷却塔一次，十天至十五天更换水槽内的水，（以免影响材质）三个月轴承注油，免干燥损坏，移位。

常见小问题  Common small problem

●冰水循环：进料的喷水管出水量小

　　　原因：1.水槽吸水口粗过滤网赌了碎胶料。

　　　2.管道过滤器的不锈钢滤网堵塞

清洗方法：务必停机水泵，取出滤网清洗干净。装好方可开机。

●热水循环：手摸冷却塔的水温感觉比常温高。原因：冷却塔高温状态易产生污垢，循环水量不够，散热管道不通畅。

清洗方法: 1. 先将冷却塔底盘污垢打扫干净。

　　　　　2. 重新加水添加适量除垢剂，开循环泵运行软化6-8小时。

         3. 打开冷凝端盖，用焊在钢筋上铁刷子刷通管道。

　　　　　4. 切记:需换清水三次，方可正常使用避免除垢剂腐蚀水泵元件及制冷管道。

●高压跳: 1. 冷却塔污垢积太多，冷却塔喷水转盘堵塞不转等。

              2. 水泵坏。冷却塔风机不转。

　　　　3. 冷凝管道污垢机过多。

　　　　4. 叶轮堵塞，不自动补水等以上原因引起流动不够，水压太小而跳。

              5. 冷却塔配套不对，如十匹应配十吨冷却塔。

               6. 制冷剂注入量过多或更换部件时没有经严格真空，系统含有空气。

●低压跳：1. 冰水通道堵塞（参考冰水循环排除）引起蒸发钛炮结霜。

                2. 制冷剂漏到静止不足五公斤时。

                3. 冷媒通道微堵不顺口，如过滤器进出有温差，手阀进出有温差。

                4. 冰水泵配置不够功率。

少见故障  Rare fault

压缩机不工作：1. 冰水泵正常运转否。

                        2. 热水器正常运转否。

                        3. 冰水热水泵均正常方能启动压缩机。

                        4. 检查空气开关，接触器，继电器，压力开关，温控器等电路由专业电工检修。

Purpose:  Used to cool the water in the sink

Advantage:  According to the water quality of the flume contains anti - adhesive chemical products corrosion high disease，Pure titanium tube evaporator，Good heat transfer corrosion resistance，The shortcomings of traditional copper tube evaporator are improved.

Cooling Machine：Installation instructions

Public equipment：Power: 380V,50Hz.

●①Pipe pump:2.2kw two sets.

  ②Cooling tower: 15tons

  ③Plastic pipe(1.5inches)to water pipe（0.4 inches）

  ④ Host power line: 10 mm²four-core

  ⑤ Water pump:2.5 mm² three-core

●Start work: the steps of start-up: start up in ten minutes

1. Close the ice water circulation

2. Close the hot water circulation pump

3. Close compressor circulation pump

●After work: the steps of end power at any time:

1. Sconnect compressor

2. Disconnect hot water circulation pump

3. Disconnect the ice water pump

●Hand over:1.We should record the data as follow: the normal value of high-low pressure (kilograms),The setting value of high-low pressure controller (kilograms),The running current (amperes),The setting value of protection (amperes)

2. Please refer to the above normal values before the machine maintenance, clean cover and the position of oil in order to be convenient for repairman to operate.

3. Air switch can’t be change to a bigger one, in case of burning compressor.

Maintenance

Clean cooling tower at every three monthes, change the sink’s water at every ten days to fifteen days, (so as not to affect the material) infuse the oil into bearing at every three monthes, avoid dry damage, shift.

FAQ

●Ice water circulation: The water yield of the feed-in spray pipe is small.

Reasons: 1.The fragmentary rubber compoud is pluged up because

of the water sucking mouth of sink is thicker than dust gauze.

2. The stainless steel strainer of piping filter is pluged.

The cleaning method: Be sure to stop the pump, take out mesh to clean. Boot only after pack.

●Hot water circulation: The feeling temperature by touching cooling tower is higher than normal temperature.

Reason: The cooling tower is easy to produce dirt at high temperature, circulation water is not enough, heat pipe is obstructed.

The cleaning method:

1. First clean the cooling tower chassis’s dirt.

2. Add water and appropriate cleaner, open cycle pump running softening for 6-8 hours.

3. Open the cover of condensation, brush the pipeline by iron brush on steel bar.

4. Remember: change clear water three times to avid that cleaner corrode pump components and refrigeration pipeline corrosion.

●High pressure jump:

1. The cooling tower has too much dirt, the water spray of the cooling tower is jamed and not work.

2. Water pump doesn’t work. The fan of cooling tower doesn’t work.

3. Condensation pipes have too much dirt.

4.Impeller congestion, not to be automatic to fill water etc, these reasons cause the water flow is not enough, and water pressure is too small to lead to jump.

5. Cooling tower is in supporting the wrong horse, such as ten horse should match ten tons of cooling tower.

6. The injection quantity of refrigerants is too much or when replace parts without the strict vacuum, containing the air in the system.

●Low pressure jump

1. The cool water channel is jamed (reference ice water circulation to exclude) which cause evaporation titanium gun frost.

2. Refrigerants lead to the static is not to have five kilograms.

3. Cold channels micro plug, such as filters have different temperature in into and out of.

4. Ice water pump configuration doesn’t reach enough power.

Rare glitches

Compressor doesn’t work:

1. Whether the ice water pump works normally.

2. Whether the hot water pump operates normally.

3. he compressor can only be started after the ice water pump and hot water pump surely work normally.

4. Check air switch, contactor, relay, pressure switch, the thermostat and other circuits are checked and repaired by professional electricians.
