Nowadays, due to the rapid increase of vehicles in the city, highway guardrails will undoubtedly play an important role in the traffic of today's busy highways. Its role is not only to maintain good traffic order and improve road traffic safety, but also to be a city sight. An important part of. Humanity is increasingly demanding the street environment. For the safety of the general public, the relevant departments use various barriers to separate the city’s motorized and non-motorized lanes from the sidewalks. However, with the appearance of a large number of guardrails, the cleaning guardrails have been Become a headache for major environmental protection agencies. In the past, some urban cleansing fences were implemented using human-sea tactics and public-welfare labor, which were solved through schools, military units, and relevant agencies. It is no longer possible to use this method nowadays. Nowadays, in the era of market economy, large-scale recurrent regular public welfare activities cannot be carried out frequently. Therefore, workers can only be hired to scrub, the wages of wage earners are high and the cost is high. And the scrubbing efficiency is low, labor intensity is high, and more importantly, it is not safe. This can only be operated with the machine. Brief introduction of product performance principle; The cleaning vehicle is based on the modification of Jiangling's second-class chassis, discharges the Daguo III standard, and is of reliable quality and powerful power. It can fully automatic high-speed cleaning, brushing various forms of urban rails, and is widely used in urban roads. Isolation barriers, scrubbing of walls on both sides of the road, high pressure water pumps, water guns. The system adopts two-washing, two-sided and two-washing cleaning processes. The two sides are cleaned at the same time, making the cleaning more thorough. It can also perform single-side cleaning according to the needs of on-site operations. The road isolation barrier cleaning vehicle is based on the introduction and digestion of advanced technologies from the world and is designed and manufactured in accordance with China's actual conditions. The principle of brushing and protecting the fence is as follows. First, two rows of high pressure water jets in front of the brush roll spray water to fully protect the fence. Pre-wet, during the forward movement of the car body, the roller brush then rotates and clamps the fence to scrub the guardrail in all directions. Finally, the rear two rows of high-pressure water jets spray water to flush away the residual dust, and the brushed guardrail Bright as new. The product's advancedness, reliability and rationality of program design 1. Product advancement: 1. Built-in brush roller can be used to adjust the brush roller according to the width and height of the guardrail. After the operation is completed, it can be returned to the container. , Chain type automatic doors fall, so that the overall appearance of the road isolating and protecting the cleaning vehicle is good, the flow linearity is good; 2. Intelligent support wheel device design), to ensure the stability and safety of the vehicle when working; 3, the operating mechanism The electric, liquid and gas centralized systems are controlled automatically. The vehicle has a good man-machine interface and is easy to operate. The driver can complete various operations in the cab equipped with air-conditioning, which is safe and comfortable. 4. Hydraulic oil cooling is designed. Automatic control system, so that the oil temperature is always at the best working temperature, improve the hydraulic work efficiency and system life and safety; 5, the use of large-diameter multi-corner bristles, the work efficiency is higher, and effectively protect the work finish layer; 6, Special brush mounting structure design, quick replacement of bristles, reliable and convenient installation and operation; 7, external cleaning cover installation , Can meet the city a variety of barriers single-sided, double-sided operation requirements, the operation more convenient, safe; 8, the job gap is accurately adjustable, stable and reliable, to meet the needs of stainless steel, spray and other types of width of different guardrail cleaning operations, but also Can clean the trapezoidal bottom pier; 9, equipped with high pressure water pump, water gun (standard), can complete the high-pressure flushing operations; 10, with a front-mounted side fence cleaning system, can be used for roadside double fence cleaning operations. Second, product reliability Each action uses full hydraulic control, which greatly improves the reliability of the cleaning system and the accuracy of the action; Safe Operating Procedures 1. Drivers should wear company-supplied uniforms, work cards, and reflective clothing. 2. The washing vehicle must not be retrograde during the flushing operation. It is not allowed to reverse the cleaning of the guardrail, obey the traffic rules, and drive in a civilized manner. 3. The warning light must be turned on during the flushing operation, and the width light must be turned on during the night operation. 4. The prompt music must be used during the flushing operation, and the prompting music must be lowered or turned off during the night operation. 5. The speed should be ≤8km/h when washing. 6. Pay attention to avoiding pedestrians during flushing operations and try to avoid peak traffic times. Vehicle Equipment Requirements 1. All work vehicles are installed in accordance with the requirements of the purchaser GPS positioning system and with the access to the purchaser of the digital monitoring system, written commitment to all work vehicles dedicated to the tender service. 2. Our company promises to equip vehicles and equipment as well as other vehicles and equipment, and promises that damaged vehicles and equipment will be repaired or replaced in time during service. 3. The equipment held by our company is newly purchased. 4. All work vehicles are installed in accordance with the requirements of the purchaser GPS positioning system and with access to the purchaser of the digital monitoring system, our company promised that all the above-mentioned work vehicles dedicated to this tender service. All vehicles and equipment are used for this project. 5. All working vehicles should be uniformly labeled, standardized and clear in accordance with the requirements of the purchaser. Cleaning process of guardrail cleaning vehicle 1. The guardrail cleaning vehicle must fetch water from the designated hydrant. 2. Perform a major clean-up of public utilities, bus stops, and subway station entrances and exits during major events and before inspections. 3. Rinse the guardrail to the basic color, wash the contaminated guardrail in time. 4. Fence cleaning operations shall be carried out on all roads and shall not be missed. The guardrail shall be clean after cleaning. If necessary, use a cleaning agent to reach the true color of the guardrail, free of oil, dirt, chewing gum and other dirt.  Oil Pan Gasket function is to seals the oil pan to the bottom of the engine.

Oil Pan gasket Material: Cork, Framework Rubber, Metal Rubber. Sealing Paper,
1 CORK: Cork material is the earliest used in the oil pan seal. The most widely applied, Is a highly applicable sealing material. It is feather is: simple process, raw material is simple and easy. Low cost.
But a wide range of apply does not mean it`s fully suited to the oil pan seal.
Its disadvantage is also very obvious: Easy to leak; Easy to pressure explosion when install the screws.
European and American manufacturers have no longer use this material many years ago, but the aftermarket still have a huge inventory fort this cork oil pan gasket.
2 RUBBER: Rubber oil pan gasket is widely used in the foreign maintenance market, It`s a very nice sealing material, The specific material can be: NBR, ACM,FKM. European cars prefer to use rubber oil pan gasket, such as Mercedes-Benz, Audi, and Volkswagen and so on.
3 Sealing Paper: Sealing paper oil pan gasket is a new material, it`s performance stable, good sealing effect, Suitable for flat sealing. The US repair kits form TTK,ATC,TRANSTEC etc- are mostly use this sealing paper material.
4 Metal Rubber: Also named as module rubber, hard rubber, its use metal as a skeleton and coated with rubber outside, representative one like 4T65E, This is a new trend of the oil pan gasket, It combines the advantages of rubber material and avoid the disadvantage of not easy to fix. At present United States almost all new transmission box is use this metal rubber sealing gaskets. This is also widely used in the engines.
