●上班：開機順序：提分鐘開機

1. 閉合冰水循環泵

2. 閉合熱水循環泵

3. 再閉壓縮機循環泵

●下班：隨時斷電順序：

　1. 斷開壓縮機

2. 斷開熱水循環泵

3. 斷開冰水泵

●移交時：1. 高低壓的正常值是幾公斤，高低壓控制器的設定值是幾公斤，進行電流是幾安，設定保護值是幾安，均要記錄。

2. 機臺維修前請參考以上的正常值，維修前要清洗干凈外觀和油漬的位置，便于電工機修工維修人員的操作。

3. 空氣開關不可以隨意換大的，以免燒毀壓縮機。

維修保養  Maintenance

保養定為三個月清洗冷卻塔一次，十天至十五天更換水槽內的水，（以免影響材質）三個月軸承注油，免干燥損壞，移位。

常見小問題  Common small problem

●冰水循環：進料的噴水管出水量小

　　　原因：1.水槽吸水口粗過濾網賭了碎膠料。

　　　2.管道過濾器的不銹鋼濾網堵塞

清洗方法：務必停機水泵，取出濾網清洗干凈。裝好方可開機。

●熱水循環：手摸冷卻塔的水溫感覺比常溫高。原因：冷卻塔高溫狀態易產生污垢，循環水量不夠，散熱管道不通暢。

清洗方法: 1. 先將冷卻塔底盤污垢打掃干凈。

　　　　　2. 重新加水添加適量除垢劑，開循環泵運行軟化6-8小時。

         3. 打開冷凝端蓋，用焊在鋼筋上鐵刷子刷通管道。

　　　　　4. 切記:需換清水三次，方可正常使用避免除垢劑腐蝕水泵元件及制冷管道。

●高壓跳: 1. 冷卻塔污垢積太多，冷卻塔噴水轉盤堵塞不轉等。

              2. 水泵壞。冷卻塔風機不轉。

　　　　3. 冷凝管道污垢機過多。

　　　　4. 葉輪堵塞，不自動補水等以上原因引起流動不夠，水壓太小而跳。

              5. 冷卻塔配套不對，如十匹應配十噸冷卻塔。

               6. 制冷劑注入量過多或更換部件時沒有經嚴格真空，系統含有空氣。

●低壓跳：1. 冰水通道堵塞（參考冰水循環排除）引起蒸發鈦炮結霜。

                2. 制冷劑漏到靜止不足五公斤時。

                3. 冷媒通道微堵不順口，如過濾器進出有溫差，手閥進出有溫差。

                4. 冰水泵配置不夠功率。

少見故障  Rare fault

壓縮機不工作：1. 冰水泵正常運轉否。

                        2. 熱水器正常運轉否。

                        3. 冰水熱水泵均正常方能啟動壓縮機。

                        4. 檢查空氣開關，接觸器，繼電器，壓力開關，溫控器等電路由專業電工檢修。

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.
