Cleaning the car type Generally, it is classified according to the way of walking, method of operation, or dust removal A hand-propelled sweeper and a hand-held sweeper A self-propelled sweeper Pure scavenging car 4, sweep sweeping car Pure suction sweeper Dry cleaning car Wet cleaning car All-smoking sweeping car The dry cleaning car is introduced Dry cleaning the car is a new type of road sweeper, not without a brush spray, all air assignments, by aerodynamics, by experts identified the domestic leading technology, and with independent intellectual property rights, development, and developed by luoyang chi windmill industry co., LTD., the production of road jie brand series vacuum sweeper all airflow, brush, spray, without a dust, without secondary dust, road clean vacuuming the widespread use of car will greatly reduce the content of particulate matter in the air, thoroughly solved the problem of the dust pollution is serious, is a modernized new sanitation product environmental protection, energy saving, the environmental protection technical indexes of this product is higher than the national industry standard. Pure suction sweeper Pure suction road sweeper is a new high-tech product that is "no secondary dust pollution and function superior to traditional sweeper". The vehicle adopts the principle of negative pressure pure absorption by the dust collection system, a dust collecting box, secondary dust collection box, dust collection system, hydraulic system, this sheng dust removal filter cartridge, and electric control system of walking system, etc, with high dust collection range, the net absorption rate, no secondary dust suction, and outlet no dust emissions, high working efficiency, etc. Is the preferred product for sanitation clean and material recycling. Suitable for the industrial and mining enterprises that produce dust, high concentration and high density of dust and dust; The rapid cleaning and cleaning of urban elevated, fast roads and tunnels; Cleaning and cleaning of main street, high grade highway and highway. The dry cleaning car is introduced Dry cleaning the car is a new type of road sweeper, not without a brush spray, all air assignments, by aerodynamics, by experts identified the domestic leading technology, and with independent intellectual property rights, development, and developed by luoyang chi windmill industry co., LTD., the production of road jie brand series vacuum sweeper all airflow, brush, spray, without a dust, without secondary dust, road clean vacuuming the widespread use of car will greatly reduce the content of particulate matter in the air, thoroughly solved the problem of the dust pollution is serious, is a modernized new sanitation product environmental protection, energy saving, the environmental protection technical indexes of this product is higher than the national industry standard. Multi-function all-suction cleaning car Multi-functional total suction sweep road car is to use the patent technology development of new products, it has changed the past the traditional method for cleaning the car plate rolling brush brush sweep, but all adopt the airflow to finish the homework, using air movement mode to hoard dust and garbage collection, so the efficiency is very high. This product can reduce dust pollution effectively, improve air quality, reduce the amount of particulate matter in air, and improve people's living environment. Why do you need to use a sweeping car The traditional answer: sweep the road to clean the floor, wash the floor to wash and dry all kinds of ground. The professional answer: the road car can not only solve the problem but also make more profit for the user. The sweeping car can solve the following problems: People live in a dusty environment with health problems; Environmental indicators required by state laws or local regulations; A problem caused by premature excess of the road due to dust or garbage; The product of the production workshop is contaminated by dust; The problem of dust pollution of fixed or moving machines in production workshops; The ability to bring greater profits (or savings) : The sweeping vacuuming system of sweeping cars is equivalent to about 6-40 times artificial; The level of 2, reduce dust pollution to the environment (to save time and money, reduce artificial cleaning of product appearance, cleaning and maintenance of mechanical equipment and periodic health work environment, etc.) Improve the efficiency of work and increase the motivation of the operator. A clean and tidy environment not only improves the image of the city, but also contributes to the construction of urban culture and the initiative of the citizens. The comparison between the mechanical and the manual 1, work efficiency, the same homework area time is greatly shortened; The clean cost of the mechanical unit area is, to be sure, lower than the artificial cost. Clean effect, the machine can avoid the problem that the cleaner USES not average, the clean effect is not unified; 4, safety performance, let clean workers in the safe environment (the traffic on the road is too much, and the safety of the self is not strong). Economic returns, for example, take a car for example, how much money it spent on the day it stopped using, the real price. In addition to the cost of investment, there are operational costs and labor costs. Sweep road car industry in China after decades of development, products from a single pure sweep type development to the present a variety of types, product performance and product quality rapidly improved, especially after the reform and opening up, by importing key purchased components to sweep road car product performance and reliability is greatly increased. But at present, the level of the road car in China is different from that of developed countries in other countries, especially in the reliability of the product. To improve the level of the sweep road car as soon as possible, reducing the gap with advanced countries sweep road car, meet the requirements of the sanitation department for road surface cleaning operation in our country, sweep road car production enterprise should choose an appropriate sweep road car research direction. With the development of the society, the progress, are no longer satisfied with the simple sense of vacuum sweeper, will from the perspectives of multifunctional, environmental protection, economy, to ask for more, call can satisfy the various needs of vacuuming car market. Is under such circumstances, the Chinese construction bureau of luoyang construction machinery factory and luoyang chi windmill industry co., LTD. Jointly developed with independent intellectual property rights of new multifunctional suction all sweep road car is now officially put on the market. The new model can be a complete surface cleaning, the road road teeth cleaning, the road road teeth cleaning and cleaning the sprinkling water on the ground after work and so on, is suitable for various climate and dry pavement cleaning operation, more suitable for square, roads, residential district, parking lot, wharf, airport, station, cement plants, power plants and other places clean dust removal. In order to avoid operation error, the control valve mainly distinguishes the main valve and the auxiliary valve. Then the two valve is, where is the main difference, the main valve driven by sweep road car chassis, vice valve power from the special function of the engine. The common engine of the road scavenging car has the north facing the wood, the jiangling, cummins. Main valve management chassis shell carriage tilt and carriages behind the back door of hydraulic pressure switch, the deputy valve management four brush to sweep road car (can be individually controlled one or all of the work) and suction cups. 2, the engine's secondary engine is different from the engine, but the average speed is around 1500 to 1800 3, according to the needs of work, generally can choose whether to take water spray dust function, general configuration generally take after water spray, also need to pay attention to the clear water tank of water is enough, clear water tank volume, working time may have difference. 4, the road sweepers electromagnetism multi-channel valve pressure adjustment is normally on the overflow valve, the user can adjust the pressure appropriately to change the speed of the sweeping brush. 5, additional sweeper can choose according to the road vehicle whether brush to brush on the left and the right to work at the same time, such as sweeping the road corner is only open one side of the brush rotation work here in the corner 6, the dustbin of the scavenging car may have small dust deposits, and manual processing is required to clean up the dustbin. 7, the distance from the sweeping car to the ground should be adjusted according to the condition of the road. The scavenging tube may often have dirt and mud, and it will need to be cleaned up regularly for better results. 9, control the electrical parts of the box in order to use a more stable need to replace a piece. 10, the sanitation worker should regularly check whether the functional areas are normal In order to avoid the effects of foreign bodies in hydraulic oil on the normal operation of the electromagnetic control valves, the sanitation workers should check the hydraulic oil regularly. 12, it is normal to check the limit device of the clutch power push rod of the engine. 13, the time interval should be five seconds when the floor is converted 14, when a hydraulic part of a road sweeper is not working properly, check the oil circuit before checking the circuit. (1) the reason that the circuit is partially abnormal may be: insurance disconnection, line connection looseness, line break (2) there may be reasons for the abnormal flow of oil: the oil pump failure, the breakdown of the tubing, the leakage of oil from the oil circuit, and the failure of the solenoid valve.

道路清掃車是集路面清掃、垃圾回收和運輸為一體的新型高效清掃設備。簡單的說就是在專用汽車底盤上改裝道路清掃功能的掃地車型，車輛除底盤發(fā)動機外，另外加裝一個副發(fā)動機，四把掃刷由液壓馬達帶動工作，帶風機、垃圾箱、水箱等多種配套設備。這種全新的車型可一次完成地面清掃、馬路道牙邊清掃、馬路道牙清洗及清掃后對地面的灑水等工作,適用于各種氣候和不同干燥路面的清掃作業(yè)。 清掃車類型 一般以行走方式、作業(yè)方式或除塵方式來進行分類，通常多以作業(yè)方式分類 1、手推式清掃車和手扶式清掃車 2、自行式清掃車 3、純掃式清掃車 4、吸掃式清掃車 5、純吸式清掃車（多功能全吸式掃路車） 6、干式清掃車（吸塵車） 7、濕式清掃車 8、全吸式清掃車 干式清掃車介紹 干式清掃車就是一種新型道路清掃車，不用刷子不噴水，全部氣流作業(yè),靠的是空氣動力學原理, 經(jīng)專家鑒定國內(nèi)領先技術，且擁有獨立的知識產(chǎn)權(quán)，洛陽馳風車業(yè)有限公司自行開發(fā)、研制、生產(chǎn)的路潔牌系列吸塵車全部用氣流，不用刷子、不噴水，沒有一次揚塵、沒有二次揚塵，路潔吸塵車的廣泛使用將大大減少空氣中可吸入顆粒物的含量，徹底解決了粉塵污染嚴重的問題，是一種環(huán)保、節(jié)能的現(xiàn)代化新型環(huán)衛(wèi)產(chǎn)品，這種產(chǎn)品的環(huán)保技術指標高于國家行業(yè)標準。 純吸式清掃車 純吸式道路清掃車是一種“無二次揚塵污染、功能上優(yōu)于傳統(tǒng)掃路車”的全新高科技產(chǎn)品！ 該車采用負壓純吸的原理，由吸塵系統(tǒng)、一次集塵箱、二次集塵箱、粉塵回收系統(tǒng)、液壓系統(tǒng)、今盛除塵濾筒、電控系統(tǒng)及行走系統(tǒng)等組成，具有吸塵范圍廣、吸凈率高、吸口無二次揚塵、出風口無粉塵排放、工作效率高等優(yōu)點，是環(huán)衛(wèi)清潔及物料回收的優(yōu)選產(chǎn)品。適用于于易產(chǎn)生揚塵污染的多粉塵、高濃度和大密度的工礦企業(yè)；城市高架、快速道路及橋隧的快速清掃保潔；城市主干道、高等級公路及高速公路的清掃保潔。 干式清掃車介紹 干式清掃車就是一種新型道路清掃車，不用刷子不噴水，全部氣流作業(yè),靠的是空氣動力學原理, 經(jīng)專家鑒定國內(nèi)領先技術，且擁有獨立的知識產(chǎn)權(quán)，洛陽馳風車業(yè)有限公司自行開發(fā)、研制、生產(chǎn)的路潔牌系列吸塵車全部用氣流，不用刷子、不噴水，沒有一次揚塵、沒有二次揚塵，路潔吸塵車的廣泛使用將大大減少空氣中可吸入顆粒物的含量，徹底解決了粉塵污染嚴重的問題，是一種環(huán)保、節(jié)能的現(xiàn)代化新型環(huán)衛(wèi)產(chǎn)品，這種產(chǎn)品的環(huán)保技術指標高于國家行業(yè)標準。 多功能全吸式清掃車 多功能全吸式掃路車是采用專利技術研制的新產(chǎn)品，它改變了以往清掃車用盤刷滾動刷掃的傳統(tǒng)方式，而全部采用氣流來完成作業(yè)，利用氣流運動方式將粉塵和垃圾收集儲存起來，因此效率很高。本產(chǎn)品可有效減少粉塵污染，提高空氣質(zhì)量，降低空氣中可吸入顆粒物的含量，改善人們的生活環(huán)境。 為何需要使用掃路車 一、傳統(tǒng)的回答：掃路車用來掃地，洗地車用來清洗并擦干各種地面。 二、專業(yè)的回答：掃路車不僅能夠解決困難還能夠為使用者獲得更多的利潤。 三、掃路車能夠解決以下問題： 1、人們生活在滿是灰塵的環(huán)境中的健康問題； 2、國家法律或地方法規(guī)要求的環(huán)境指標； 3、由于灰塵或垃圾而造成路面過早過度的破損問題； 4、生產(chǎn)車間的產(chǎn)品被灰塵污染的問題； 5、生產(chǎn)車間內(nèi)固定或移動的機器被灰塵污染的問題； 四、能夠帶來更大的利潤（或節(jié)約開支）： 1、掃路車的掃地吸塵系統(tǒng)相當于6-40倍的人工； 2、減少灰塵對環(huán)境污染的程度（節(jié)約時間和財力，減少人工對產(chǎn)品外表的清潔， 對機械設備的清潔保養(yǎng)以及周期性的環(huán)境衛(wèi)生工作等） 3、提高工作效率，同時提高操作者的工作積極性； 4、一個良好整潔的環(huán)境不僅提高城市形象，而且更有利于城市文化的建設及市民工作的積極性。 五、掃路車機械與人工的比較 1、工作效率，同樣的作業(yè)面積時間上大大縮短； 2、清潔成本，可以肯定的是機械單位面積的清潔成本比人工還要低； 3、清潔效果，機械可以避免清潔劑使用不平均，清潔效果不統(tǒng)一的問題； 4、安全性能，讓清潔工人身處安全環(huán)境（馬路上的車輛太多，自身的安全意識不強） 5、經(jīng)濟回報，以一輛車為例，它停止使用的那天共花費了多少錢，才是它真正的價錢。除了投資成本外，還有運營成本和人力消費成本。 我國掃路車行業(yè)歷經(jīng)數(shù)十年的發(fā)展，產(chǎn)品從單一的純掃式發(fā)展到目前的多種型式，產(chǎn)品性能和產(chǎn)品質(zhì)量迅速提高，特別是在改革開放以后，通過進口關鍵外購件使掃路車產(chǎn)品性能和可靠性大大提高。但目前我國掃路車的水平與國外發(fā)達國家相比，還存在一定的差距，特別是在產(chǎn)品的可靠性方面。為盡快提高我國掃路車的水平，縮小與先進國家掃路車水平的差距，滿足我國環(huán)衛(wèi)部門對路面清掃作業(yè)的要求，掃路車生產(chǎn)企業(yè)應選擇一個合適的掃路車研究方向。隨著社會的發(fā)展、進步，不再滿足于單純意義上的吸塵車，將從多功能、環(huán)保、經(jīng)濟等方面提出更多的要求，市場呼喚能滿足各種需求的吸塵車。就是在上述情況下，由中國建筑二局洛陽建筑工程機械廠與洛陽馳風車業(yè)有限公司聯(lián)合研制的具有自主知識產(chǎn)權(quán)全新的多功能全吸式掃路車目前已正式投放市場。這種全新的車型可一次完成地面清掃、馬路道牙邊清掃、馬路道牙清洗及清掃后對地面的灑水等工作，適用于各種氣候和不同干燥路面的清掃作業(yè)，更適合于廣場、公路、住宅小區(qū)、停車場、碼頭、機場、車站、水泥廠、電廠等場所的清潔除塵。 1，為避免操作失誤，掃路車控制閥主要區(qū)分為主閥門和副閥門。那么這兩種閥門主要的區(qū)別又在哪里呢，主閥門的動力來自掃路車底盤，副閥門的動力來自專用功能部分的副發(fā)動機。常見的掃路車副發(fā)動機有朝柴、江鈴、康明斯。主閥門管理底盤后面的外殼車廂傾斜和車廂后門的液壓開關，副閥門管理掃路車的四把地刷（可單獨控制一面或全部工作）和吸盤的工作。 2，掃路車的副發(fā)動機因為選用發(fā)動機品牌不同功率不同，不過一般的的轉(zhuǎn)速在1500轉(zhuǎn)-1800轉(zhuǎn)左右 3，根據(jù)工作需要一般可以選擇是否需要帶噴水降塵功能，常規(guī)配置一般自帶后噴水，同時需注意清水箱水量是否夠用，一般清水箱容積不同，工作時間可能有差距。 4，道路清掃車電磁多路閥壓力調(diào)節(jié)一般在溢流閥上，用戶可以適當調(diào)節(jié)壓力來改變掃地刷的轉(zhuǎn)速。 5，另外掃地車可根據(jù)路面情況選擇車輛左邊地刷和右邊地刷是否同時工作，如掃路邊角落則只用開啟靠角的一邊地刷轉(zhuǎn)動工作 6，掃路車的垃圾箱可能有細小的灰塵沉積，清理垃圾箱時需要人工手動處理。 7，掃路車吸盤離地面的距離應根據(jù)路段情況經(jīng)常調(diào)整。 8，掃路車吸塵管可能經(jīng)常有塵土泥巴粘附，需經(jīng)常清理到達更好效果。 9，控制箱內(nèi)的電器部分為了使用更穩(wěn)定需要更換時最好是拆一件換一件。 10，環(huán)衛(wèi)工人應該經(jīng)常定期檢查各功能部位是否正常 11，為了避免液壓油中的異物會對電磁控制閥的正常工作造成影響，環(huán)衛(wèi)工人應定期檢查液壓油是否正常。 12，經(jīng)常檢查車輛副發(fā)動機的離合器電動推桿的限位裝置是否正常。 13，掃地車控制鈕轉(zhuǎn)換時，時間間隔應為5秒 14，當?shù)缆非鍜哕嚨哪骋簤杭ぷ鞑徽r，按步驟先檢查油路再檢查電路。 （1）電路部分不正?？赡艿脑蛴校?保險斷開、
