常見小問題(ti)  Common small problem

●冰水循環：進料(liao)的噴水管出水(shui)量小

　　　原因：1.水槽(cao)吸水口粗過濾(lǜ)網賭了碎膠料(liao)。

　　　2.管道(dào)過濾器的不鏽(xiu)鋼濾網堵塞

清洗方法：務(wù)必停機水泵，取(qu)出濾網清洗幹(gan)淨。裝好方可開(kāi)機。

●熱水循環：手(shǒu)摸冷卻塔的水(shuǐ)溫感覺比常溫(wen)高。原因：冷卻塔(ta)高溫狀态易産(chǎn)生污垢，循環水(shui)量不夠，散熱管(guǎn)道不通暢。

清洗(xǐ)方法: 1. 先将冷卻(què)塔底盤污垢打(dǎ)掃幹淨。

　　　　　2. 重(zhong)新加水添加适(shì)量除垢劑，開循(xun)環泵運行軟化(huà)6-8小時。

         3. 打開冷凝端蓋(gài)，用焊在鋼筋上(shàng)鐵刷子刷通管(guan)道。

　　　　　4. 切記:需換清水三(san)次，方可正常使(shi)用避免除垢劑(ji)腐蝕水泵元件(jian)及制冷管道。

●高(gao)壓跳: 1. 冷卻塔污(wū)垢積太多，冷卻(què)塔噴水轉盤堵(dǔ)塞不轉等。

              2. 水泵(bèng)壞。冷卻塔風機(ji)不轉。

　　　　3. 冷凝管道(dao)污垢機過多。

　　　　4. 葉(yè)輪堵塞，不自動(dòng)補水等以上原(yuán)因引起流動不(bu)夠，水壓太小而(ér)跳。

              5. 冷卻塔配套(tao)不對，如十匹應(ying)配十噸冷卻塔(tǎ)。

               6. 制冷劑注入量(liang)過多或更換部(bu)件時沒有經嚴(yan)格真空，系統含(hán)有空氣。

●低壓跳(tiào)：1. 冰水通道堵塞(sai)（參考冰水循環(huán)排除）引起蒸發(fa)钛炮結霜。

                2. 制冷(leng)劑漏到靜止不(bú)足五公斤時。

                3. 冷(leng)媒通道微堵不(bu)順口，如過濾器(qì)進出有溫差，手(shou)閥進出有溫差(chà)。

                4. 冰水泵配置不(bú)夠功率。

少見故(gù)障  Rare fault

壓縮機不工(gōng)作：1. 冰水泵正常(chang)運轉否。

                        2. 熱水器(qì)正常運轉否。

                        3. 冰(bing)水熱水泵均正(zhèng)常方能啓動壓(ya)縮機。

                        4. 檢查空氣(qi)開關，接觸器，繼(jì)電器，壓力開關(guān)，溫控器等電路(lu)由專業電工檢(jian)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.
