Below FT will introduce how to remove excavator hydraulic cylinder to replace and repair

1. Before disassembling the hydraulic cylinder, the fortunepart hydraulic circuit should be relieved of pressure. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, the high-pressure oil in the circuit will be sprayed out quickly. When depressurizing the hydraulic circuit, first loosen the handwheel or pressure regulating screw at the relief valve, etc., to unload the pressure oil, and then cut off the power or power source to stop the hydraulic device.

2. During disassembly, prevent damage to the top thread of the piston rod, the thread of the oil port, the surface of the piston rod, and the inner wall of the cylinder liner. In order to prevent the slender parts such as the piston rod from bending or deforming, the stow should be used to support the balance during placement.

3. The disassembly must be carried out in order. As the structure and size of various hydraulic cylinders are not the same, the disassembly sequence is also slightly different. Generally, the oil in the two chambers of the cylinder should be drained, then the cylinder head should be removed, and finally the piston and piston rod should be removed. When disassembling the cylinder head of the hydraulic cylinder, special tools should be used for the key or snap ring of the internal key type connection, and the use of flat shovel is prohibited; the flange type end cap must be pushed out with screws, and hammering or hard prying is not allowed . When the piston and piston rod are difficult to withdraw, they should not be forced out. The reason should be found out before disassembly.

4. Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being contaminated by surrounding dust and impurities. For example, the disassembly should be carried out in a clean environment as much as possible; after disassembly, all parts should be covered with plastic cloth, not cotton cloth or other working cloth.

5. After the oil cylinder is disassembled, check carefully to determine which parts can continue to be used, which parts can be used after repair, and which parts must be replaced.

Car headlight rubber cover is widely used in HID modification, used to replace the original lid.  Drill a hole in the lid, remove the wire from the HID bulb outside the headlight assembly, and seal well, waterproof and dustproof. Automotive lamps rubber dust covers also play an important role when we install LED to replace headlight bulbs.  

LED headlights have large size radiators, especially fanless LED headlights.  When installing the radiator, do not reinstall flat dust caps.  But the rubber dust cover is cylindrical and has room for heat dissipation.  Can be installed to replace the original cover plate and seal the headlight.  

When we install the LED headlight with fan, the fan is very close to the original dust cap, the air can not enter and exit, the heat dissipation system does not work well, and the LED headlight may burn out because of the high working temperature.  If we use a rubber dust cover, the fan will have enough room to circulate air.  Dust cover can prevent dust from entering headlamp housing, so that the fan work smoothly, longer service life.  

 

Some headlight holes have flat edges and no support points for dust covers;  Or if your original dust cap is too big, replace it with a rubber one of the same size.  If you encounter the above problems, the rubber dust jacket is not able to catch it.  Then we can drill a hole on the material cover of the rubber dust cover, fill the rubber dust cover in the hole, and seal it with sealant.  

 

In the installation process of refitting LED headlight bulbs, we suggest that you replace the original dust cover with black rubber dust cover to expand the indoor space and smooth the air flow.  Whether led headlights have a fan or no fan, this approach can definitely improve heat dissipation and give the bulb a longer life.

CLVEHICLES.COM has a tank body welding process for fuel tanker truck. Many users who use oil tankers must also want to know how the tanker is made. Now I will introduce the welding of the oil baffle.

Welding of the oil baffle plate of the refueling truck: the main work is the welding of the oil baffle plate in the cylinder body. According to the above, three oil baffle plates are generally arranged inside the 6M long cylinder body, and the cylinder body is divided into four compartments. Each oil baffle plate The plate must be intermittently welded with the cylinder body. If it is a separate tank, the oil baffle will be replaced by a partition, and continuous welding must be carried out. The length of each girth weld is based on the aforementioned 6-7.5M length. The continuous welding is calculated according to half of the welding length. The total welding length of this station is about 20M, and the welding speed is calculated at 5mm/s. The welding time is about 67 minutes. Considering the poor welding conditions in the compartment and the different compartments The delay in welding preparation time, the multi-welding time of a single-section cylinder takes about 1 hour and 20 minutes, and 2 stations are needed for the calculation of a 12M long tank, so consider a station side by side as the oil baffle welding station.



Fuel truck tank docking: the main work is tank docking and TIG welding bottoming. If the small tank is not segmented, it can be used as a tank storage station. Tank body docking mainly depends on adjusting the position of the roller frame to align the tank body, so the length of the two tank body roller frame stations can be considered when designing the station. The welding speed of TIG welding is calculated according to 2.5mm/S. It takes about 50 minutes to join the circular seam of 7.5M. The docking takes about 2 hours, so consider a side-by-side double-roller station, and a 13M long station.

Oil tank truck
Head installation: The main work is head installation and TIG welding. Head alignment and butt welding require special tooling to ensure that the welding speed and workload are the same as the butt joint of the tank body mentioned above. According to the aforementioned TIG welding speed, it is estimated that the bottom welding of the head will take about 1 hour and 40 minutes. Considering the head The installation tooling ensures fast positioning. It is estimated that a single tank can be completed in about 2 hours and 40 minutes. Therefore, it is enough to consider a side-by-side double-roller station, and a 13M long station. Adopt two cans to work at the same time to ensure the working time. Because the installation of the head needs to lift the two sections of the head from the two sections, it is necessary to place the two sections of the station at a distance of 2M. Head welding and cylinder body welding are mainly for the grinding and repairing of the tank rotating frame on the tank body, the bottom welding of the cylinder body and the head butt joint ring seam, and the cover welding. According to the above, the circular seam is calculated according to 6~7.5M, and the cover welding speed is 5mm/s, and it takes about 1 hour to 1 hour and 15 minutes. According to experience, to achieve better welding quality, it is necessary to completely remove welding defects And grinding, so the estimated grinding time is about 40 minutes, plus the time for the tank to be hung on the tank rotating frame, the total time-consuming is about 2.5 hours, so a tank station is considered. And 13M long station. Adopt two cans to work at the same time to ensure the working time.



Installation of tank reinforcement plates: mainly used for the installation of all reinforcement plates such as longitudinal reinforcement strips, transverse reinforcement strips, and pipe box bracket reinforcement panels at the bottom of the tank. Generally, two longitudinal reinforcement strips are set at the bottom of the tank, and the size is about 0.4*12M; each horizontal reinforcement board is about 0.6*0.2M, and there are about 12 pieces within the length range of 12.5M; each tube box bracket has 2 pieces About 0.1*0.1M reinforcement plate, about 24 pipe box brackets, each tank body welding length is about 80M, considering that the workpieces in this station are scattered, each reinforcement plate needs to be marked and positioned, so it is arranged in this station Three welding machines work at the same time for spot welding of various reinforcement plates.
