灑水車作為專用車中售后相對(duì)較少的車型，售后時(shí)經(jīng)常出現(xiàn)的是一些小問(wèn)題，比如環(huán)衛(wèi)綠化灑水車在用過(guò)一段時(shí)間后抽不上來(lái)水，傳動(dòng)軸也在轉(zhuǎn)，但就是水抽不上來(lái)。這個(gè)故障需要從以下幾個(gè)方面來(lái)進(jìn)行檢查與排除：
As a relatively special customer service sprinkler car models, often appear when the customer service is some small problems, such as sanitation green sprinkler in use after a period of time not pumping water, the drive shaft in turn, but is not pumping water up. This failure needs to be checked and excluded from the following aspects:
一、管道閥門(mén)打錯(cuò)位置
First, the pipeline valve position
抽水時(shí)，先將抽水管連接在法蘭盤(pán)上，然后將四位三通球閥的凹點(diǎn)位置扳**罐體管道方向（凹點(diǎn)所在方向管道為關(guān)閉狀態(tài)，即連通抽水口與泵體之間的管道），然后打開(kāi)直通球閥（手柄平行于管道時(shí)為打開(kāi)，與管道呈90度角時(shí)為關(guān)閉），這才是正確的抽水閥門(mén)位置，打錯(cuò)其中任意一個(gè)管道都不能形成通路，自然是抽不上來(lái)水的。這也是新手操作灑水車常常會(huì)遇到的問(wèn)題。
When pumping, first pumping pipe is connected to the flange, and then the four position three way valve concave position plate to the tank pipe direction (concave point direction of pipeline is closed, which is connected between the port and the suction pipe of the pump body), and then open the handle through valve (parallel to the pipe to open a 90 degree angle, and pipeline off), this is the pumping valve position of the right, the wrong one pipe can not form a natural pathway, is not on the water. This is a novice operating sprinkler often encountered problems.
二、濾網(wǎng)堵塞
Two, filter clogging
大多時(shí)候環(huán)衛(wèi)綠化灑水車抽不上來(lái)水，銷售人員都會(huì)建議客戶先清洗一下過(guò)濾網(wǎng)。濾網(wǎng)三通位于四位三通閥門(mén)與灑水泵的中間，其二個(gè)端口連接在管道上，一進(jìn)一出，另一個(gè)端口帶一個(gè)可卸式平面，由四顆螺絲連接。將螺絲卸下，拿下面板，即可將中間的濾網(wǎng)取出。將濾網(wǎng)清洗完畢按原樣裝回即可。
Most of the time the sanitation green sprinkler pumping on the water, the sales staff will advise our client to clean the filter net. Filter three is located in the middle of three four through the valve and sprinkle water pump, and the other port is connected to the pipe, one into one, the other port with a removable plane, four screws connected. Remove the screws, remove the panel, you can remove the middle of the filter. Clean the filter screen and press it back.
因?yàn)闉⑺嚥还苁菑耐饷娉榈乃?，還是從罐體內(nèi)放出的水，都必須經(jīng)過(guò)此濾網(wǎng)進(jìn)行過(guò)濾。因此，灑水車的三通濾網(wǎng)的濾芯是需要定期進(jìn)行清洗的，特別是經(jīng)常在野外進(jìn)行取水的車輛，更應(yīng)加大清理頻率。
Because the sprinkler, whether it is pumping from the outside of the water, or the release of water from the tank, it must be filtered through this filter. Therefore, the three pass filter of the filter is the need for regular cleaning of the filter, especially in the field of vehicles often carried water, but should increase the frequency of cleaning.
三、管路密封不嚴(yán)
Three, the pipeline seal is not strict
有些用戶在使用環(huán)衛(wèi)綠化灑水車進(jìn)行噴灑時(shí)，有時(shí)忘記打開(kāi)噴水頭開(kāi)頭，上車操作后發(fā)現(xiàn)不出水還繼續(xù)加油門(mén)，造成管道內(nèi)高壓水流無(wú)法噴出，只能從相對(duì)比較薄弱的管道連接處（橡膠墊片）釋放，導(dǎo)致膠墊在高壓下被擠出，從而形成管路密封不嚴(yán)。
Some users were sprayed in the use of green sanitation sprinkler, sometimes forget to open the car after the operation at the beginning of the spray head, found no water to gas pipeline caused by high-pressure water inside the door, not only ejected from junction with pipeline relatively weak (rubber gasket) release, leading to the rubber pad is extruded under high pressure, thus the formation of pipe seal.
這種情況下管道連接處一般都會(huì)出現(xiàn)滲水現(xiàn)象。用戶可將管道膠墊取出后重新組裝一遍，對(duì)變形嚴(yán)重的膠墊應(yīng)予以更換。在擰管道接頭螺絲時(shí)，應(yīng)遵循對(duì)角互擰的原則，不要逐個(gè)順序進(jìn)行操作，不要一次性將螺絲擰死，這樣才能將橡膠墊片正確地安裝上去。
In this case, there will be water seepage in the pipeline connection. The user can remove the pipe rubber pad and re assemble it again, and the rubber gasket with serious deformation should be replaced. When the pipe joint screw, should follow the principle of diagonal twist, not one by one in order to operate, do not screw the screw die, so that the correct installation of rubber gasket.
另一方面就是檢查抽水管的密封度，看看抽水管是否有破損或者裂紋、或者陰陽(yáng)端連接處沒(méi)有卡到位等等，這些都會(huì)造成水泵無(wú)法將水順序抽上來(lái)。
On the other hand is to check the sealing of the pumping pipe to see if there is damage to the pumping pipe or crack, or the junction of the junction of the Yin and Yang is not stuck in place, etc., which will cause the water pump can not be pumped up.
四、灑水車濾水器入水太深或者太淺
Four, sprinkler water filter into the water is too deep or too shallow
再就是查看灑水車濾水器是否入水太深，吸水高度大于允許高度，我們應(yīng)當(dāng)確認(rèn)濾水器吸水高度小于5米，并且足夠深置。吸水管的吸水頭必須完全放置于水下，以免空氣及入水管，導(dǎo)致真空度不良，水壓過(guò)低而無(wú)法將水吸上來(lái)。
Then see the sprinkler water filter is too deep into the water, water absorption height is greater than the allowable height, we should confirm that the water filter is less than 5 meters high water absorption, and enough depth. The suction head of the water suction pipe must be completely placed in the water, so as to avoid the air and the water inlet pipe, the vacuum degree is bad, the water pressure is too low to suck up the water.
五、引水不足
Five, water shortage
灑水車配備的是離心式灑水泵，該泵每次吸水前，必須向水泵內(nèi)加入一定量的引水，加完后必須關(guān)閉加水口。自吸式水泵**次使用時(shí)，需要加引水，以后則不必再加引水。在冬季時(shí)為避免泵體凍裂，應(yīng)將灑水車罐體內(nèi)和泵內(nèi)的余水排空，再次作業(yè)時(shí)則需要為泵內(nèi)加注引水。對(duì)于安裝在灑水車上的灑水泵，加入引水時(shí)可將抽水管一端連接在法蘭盤(pán)上，在另一端口進(jìn)行注水動(dòng)作，注水完成將該端口提升，讓水流入泵內(nèi)，即完成引水加注工作。
Sprinkler is equipped with a centrifugal pump, the pump every time before water, must be added to a certain amount of water to the pump, plus the need to close the water inlet. Self suction pump is used for the first time, need to add water, then don't need to add water. In the winter when the pump body to avoid cracking, should be more than the water tank and emptying the sprinkler pump, again when working for filling water pump. The sprinkler pump installed in the truck, adding water can be pumping pipe with one end connected to the flange on the water movement in a port, the port will complete the water, let the water into the pump, water filling is completed.
六、灑水泵真空不良
Six, sprinkler vacuum
灑水車水泵泵殼出現(xiàn)裂紋、或者葉輪、倒葉損壞、或者水封破損，都會(huì)影響真空度，出現(xiàn)水抽不上來(lái)，或者水壓過(guò)小的現(xiàn)象。用戶可根據(jù)灑水泵使用說(shuō)明書(shū)上的故障排除方法進(jìn)行維修或更換零配件。
Sprinkler pump shell cracks, or impeller, leaf damage, or seal damage, will affect the degree of vacuum, water pumping, water pressure is too small or the phenomenon. The user can repair or replace the spare parts according to the trouble shooting method of the sprinkling pump.
