Starting from September 1, 2010, Guangzhou's Pearl River Delta region will implement the National IV emission standard. At that time, the country's three-emission motor vehicles will not be able to license in the region, and many national first-tier cities will continue to implement the three national emission standards. The three national emission standard engines are divided into three types. One is the high pressure common rail technology, which is often referred to as the EFI engine. The second is the single pump, that is, the oil pump oil supply engine. The third is EGR. A secondary exhaust engine is equipped with a tail gas recycling technology that has reduced vehicle exhaust emissions.
1. Requirements for water When the sprinkler uses the river ditch or pond as a source of water, pay attention to that all the ends of the suction pipe are not in the water. In order to avoid inhaling stones or more sand and drift debris, the suction pipe end is generally provided with a filtering device, and it is forbidden to remove the filtering device during the water absorption. If the water source is shallow, it is necessary to dig up the water absorption area in advance so as to ensure that it does not contain impurities and air. Different sprinkler pumps have different requirements for water sources. Clean water pumps require no impurities in the water. Turbid water pumps require no stones and excessive sediment in the water.
2. Add water diversion Every time the centrifugal pump absorbs water, a certain amount of water must be added to the pump. After the addition, the water inlet must be closed. When the self-priming pump is used for the first time, it is necessary to add water, and it is unnecessary to add water afterwards.
3. The inlet pipe must be vacuumed The water inlet system must maintain a certain degree of vacuum before it can suck water into the tank. The inlet pipe system must be sealed reliably, the hose can not be damaged, the hard pipe can not have cracks, otherwise it will have a phenomenon of air leakage, which will result in the situation that it cannot suck water.
4. Parking stalls Before the water sprinkling vehicle or water sprinkling, the power take-off device must be parked.
5. Winter water release Before the advent of winter, the water in the pumps and pipes should be vented to prevent freezing. The northern part of the country is generally no longer under construction during the severe winter. Therefore, after the construction is completed, the water in the pump and the water pipe will be drained immediately to prevent future problems.
6. Watering precautions The front sprinkler of the sprinkler is located at a low position, close to the ground, the spray pressure is relatively large, and can be used for flushing the road surface; the position of the rear sprinkler is relatively high (the sprinkler is generally installed on the left and right sides of the sprinkler), and the sprinkler surface is wide, and can be used for highway construction and watering. When the rear nozzle is used, the front nozzle should be closed; when using the adjustable nozzle, the width of the sprinkler can be adjusted as needed. The wider the sprinkler width, the less the amount of intermediate overlap and the more uniform the sprinkler density.
7. Lubrication and fastening During the process of use, lubrication points of the transmission assembly should be regularly lubricated, and the joints should be tightened frequently to ensure normal use.
8. Regular sewage The water tank of the sprinkler truck is provided with a sewage pipe. The inlet of the pipe is the lowest point of the water tank. After a period of use, the discharge pipe switch should be opened periodically to remove the accumulated debris from the tank until the water becomes clear.
1. No response after power on. Most of them are caused by short-circuiting of power plugs, power outlets, and motor windings.
2, difficult to start or can not start, and accompanied by "squeak" sound. During inspection and repair, small bamboo strips can be used to rapidly move the blades according to the running direction. If the motor is quickly operated, it indicates that the starting capacitor or starting winding is damaged. Replace the capacitor with the same capacity or repair the starting winding. If the motor is issued, the motor and the pump head are mostly. Mechanical failure, such as bearing damage, stuck impeller and so on.
3, the motor can run, but the speed is slow, and the chassis is overheated, burned odor. Most of them are caused by the short circuit of the motor windings. The motor should be disassembled and repaired by welding, jumper, isolation, rewinding, etc., depending on the damage.
4, large noise and vibration during operation. Most of the bearings are damaged or the bearing and the chassis are not properly mated. The motor must be dismantled for inspection. If the bearings are damaged, they should be replaced. If the bearings run out of the circle, the pump shell can be mated with the stencil treatment. If the bearings run in a circle, The wear part of the motor shaft is stenciled, and the wear is serious. The repair is performed by first surfacing after welding.
Second, sprinkler pump head section 1. The motor runs normally but has little or no water. This situation should first check the sprinkler pump seal, check should first unplug the power plug, hand plug the suction port, fill the water pump, with the mouth to seal the exit and blow in the air, observe the pump head is leaking The leaking point is where the seal is damaged. Common faults include suction pad, outlet pad, and impeller cover pad, which should be replaced during maintenance. If there is no full water phenomenon, the impeller is damaged, the water-retaining partition between the water-absorbing chamber and the outlet chamber is worn out, the pump head is covered with water, and the gap between the impeller and the pump casing is increased. The impeller and the pump casing should be replaced. . When replacing the rake wheel, care should be taken to completely remove the remaining copper blades in the pump so as not to damage the new impeller again.
2, the chassis is charged. Most of them are damaged by water seals. Water penetrates into the motor through the motor shaft and deteriorates the insulation performance of the motor. It can be repaired by replacing the water seal and drying the motor. It should be noted that because the water pump is exposed to water for a long time and it is open to work in the open air, it is prone to moisture and deteriorates the insulation performance. In order to ensure personal safety, the self-priming pump of the electric sprinkler should be reliably grounded.
Sprinklers are exempted from the announcement that they will be exempted from the use of sprinklers. Customers who purchase this vehicle may be exempt from vehicle purchase tax. Exemption from exemption from purchase of additional tax
Sprinklers are exempt from vehicle purchase tax quotas: The purchase price of special invoices for motor vehicle sales includes value-added tax. Therefore, when assessing vehicle purchase tax, 17% of value-added tax must be eliminated, ie, the purchase of sprinkler vehicles. Taxes and taxation price = invoiced price is 1.17, and then the vehicle purchase tax is levied at a tax rate of 10%. Consumers purchase a 100,000 yuan sprinkler and pay 10% tax after removing the VAT portion. The formula is 100000÷1.17×0.1=8547 yuan.
Sprinkler vehicle purchase tax exemption operation procedure: To the purchase tax payment hall, the staff will provide a tax exemption card for this vehicle according to the exemption announcement, hold the tax exemption card to the local vehicle management office, and the vehicle management office will handle the relevant ownership of the vehicle. .
