With the arrival of “sauna daysâ€, the humidity of the air has increased, and the occasional heavy rains have started. The home's moisture-proof work has to start. In addition to frequent furniture cleaning, the method used for dehumidification and moisture protection should also be considered. .
Wood furniture: turn on the air conditioning dehumidification function
If the environment is in a high humidity environment for a long time, the wood will definitely swell, and when it returns to a dry environment, the structure of the wood will change, causing cracking. Therefore, wood furniture must pay attention to moisture during the rainy season. It is recommended to turn on the dehumidification function while turning on the air conditioner in summer to make the humidity and temperature of the indoor environment relatively suitable.
Wooden furniture should be cleaned with a clean two-part wet cotton towel during daily care. It is not suitable for too wet or too dry. In addition, different methods of care can be used depending on the paint film on the surface of the furniture. For example, in solid wood furniture, the furniture used for surface finishing with wood wax oil should be waxed and maintained once after half a year or one year; and the furniture of polyurethane paint film can be wiped daily without deliberate maintenance. Relatively speaking, panel furniture is less sensitive to temperature and humidity than solid wood furniture. However, no matter whether it is plate or solid wood, the bottom that is in contact with the ground cannot have water for a long time, otherwise the parts in contact with water will expand and crack.
Cloth furniture: more cleaning and more sun
The summer weather is hot and the air humidity is high, because the people who use it are prone to sweating, and the cleaning frequency of cloth furniture needs to be higher than in winter. Especially the down sofa, which is affected by the humidity, may even have an odor due to moisture. If conditions permit, you should open the window and ventilate it from time to time.
Most cloth furniture, such as fabric sofas, can be removed and cleaned on the surface. We can choose wet or dry cleaning according to the requirements of the product. After wet washing, it must be dried in the sun. After the dry-cleaning sofa cover, it is best to blow it with a hair dryer and then put it back. If you use the hot air of the hair dryer, do not leave too close when blowing, so as not to damage the original color. The surface of some cloth furniture can not be dismantled, you can find a special cleaning company to provide on-site service. If it is difficult to remove it because it is mildewed due to moisture, it can also be cleaned by a company that cleans fabrics.
Dump Truck
Dump Truck, Tipper is through hydraulic or mechanical lifting and self-unloading cargo vehicles. Also known as dumpers. From the vehicle chassis, hydraulic lifting mechanism, cargo compartment and take power plant and other components.
Scope
Dump Truck in civil engineering work and is often combined with excavators, loaders, conveyor and other construction machinery, constitute loading, transportation and unloading production lines, earthwork, gravel, bulk material handling and transportation work.
working principle
Dump truck engine, chassis and cab of the truck and the general structure of the same.
Dump the car after tipping and lateral tipping points to two types of operating system by control rod movement, backward tipping more common, pushing the piston rod so that the car tipping a few two-way tipping.
High-pressure oil through distribution valves, tubing into the lift cylinder, front-end cab car safety shield.
The engine through the transmission, PTO driven hydraulic pump unit, hydraulic tilting mechanism from the tank car, hydraulic pumps, dispensing valve, hydraulic lifting cylinders, control valves and tubing and other components.
The engine through the transmission, PTO devices driven hydraulic pump, high-pressure oil through distribution valves, tubing into the lift cylinder, push the piston rod so that the car tipping. After the tipping more common, by manipulating the system control movement of the piston rod, the car can stop at any desired position on the slant. Carriage using its own gravity and hydraulic control reset.
Taxonomy
1. In accordance with Brand:
Dongfeng truck, FAW dump truck , Auman dump truck, FOTON dump truck, heavy truck Steyr, Hongyan IVECO dump truck, JAC dump truck, FAW heavy dump truck , Shaanxi Shacman dump truck, HOWO dump truck, BEIBEN dump truck,Sino Truck Tipper.
2 according to shape classification:
Single axle dump truck, Double Axle dump truck, flat truck, tipper truck, the top four after eight 8*4 dump truck, tractor double axle dump truck, dump truck trailer Bridge
3. The species classification:
Bully dump truck, dump truck Huancavelica, 140 dump truck, dump truck 145, 153 dump truck, dump truck 1208, a small dump truck, dump truck dongfeng
4. Follow the links on the form of a hydraulic cylinder and lifting cars Category:
Direct Push tilt mechanism; link tilt mechanism.
5. Use according to category:
Agricultural dump truck, dump truck, Garbage Truck, dump truck transport of coal,
Construction machinery dump truck, dump truck sludge
6, depending on the driving mode is also divided into 6x4, 8x4 dump truck and Semi-Trailer dump truck.
7. Depending on the application is also divided into mining trucks, used to transport coal, sand and gravel; sanitation green dump truck used to transport garbage.
8, according to the car there before turning in the direction of Bootstrap and roll type dump truck. There are still two-way dump truck rollover, mainly used in construction.
The current domestic production of dump truck manufacturers have a relatively well-known Chinese heavy truck Jining Commercial Vehicle Co., Ltd., Tong Tong Group Special Vehicle Co., Ltd., China National Heavy Duty Truck Hubei Warwick Special Purpose Vehicle Co., Shaanxi Heavy Duty Automobile Co., Ltd.
advantage
Since the car can automatically load certain tipping angle discharge, saving unloading time and labor, shorten the transport cycle, improve production efficiency, reduce transportation costs, it is a commonly used special transport vehicles.
Care Tips
The new dump truck or car repair factory commissioning must be carried out so that the car ran smoothly without lifting process.
When using the various parts should be required to correct selection of lubricants, saving time and labor unloading, lifting mechanism strict schedule swap oil.
According to the rated load of the shipment, non-overloading.
Practice
1, can not be loaded in the middle of a sudden the elevator lift handle to the "down position."
In the event of this error, the car suddenly rushed down, the frame will bring a great impact, and even accidents. Therefore, we should try to avoid the above operation, if special circumstances also need to be careful, try to slow down the landing speed, the car suddenly do not have to avoid falling in the end.
2, do not mention the use of stronger car - brake suddenly unloading.
Due to fierce mention car inertial force is large (typically 5 to 20 times the rated lifting force), can easily result in permanent deformation of the frame, carriage and pay the frame open welding, burning or destruction of the pump seals, hydraulic cylinders and other damage damage , reduced service life of the vehicle, there will be severe rollover accident. Therefore, the general dump truck while driving ban lifting.
3, after the dump truck to be unloaded disengage the power take off before driving.
If this occurs operational errors, dump truck while driving, because the PTO in the "engaged" position, the lift pump is at "small cycles" state high speed for a long time no-load operation. Cause oil temperature rises rapidly, easily lead to damage to the pump seals, the pump even "burn" phenomenon; more serious is the operation of the pump means that the hydraulic system has a power source, in driving the process prone to auto-liter car since the accident.
4, with the power take off is not available in the "on" position.
If the "on" state (red light lit), the pump will continue to rotate, the hydraulic system there is a power source, so it will because the gas control valve on the steering malfunction caused by automatic car lift; gas at this time distribution valve control even in "down" position, but also into the oil pump, and the pump will burn out.
