1, pay attention to the role of cushions. The gaskets between the parts of the tank trucks at the rest positions of the car (such as the joint end faces, the end caps, the housing, the cover gaskets, the plane cover plate, etc.) function as a leak-proof seal. If the material, production quality and installation do not meet the technical specifications, it will not achieve sealing leakage, even accidents. Such as the oil pan or valve cover, due to the large contact area and difficult to compact, resulting in oil spills. When disassembling, pay attention to proper placement, carefully inspect and assemble according to specifications.
2. All types of fastening nuts for oil tankers must be tightened according to the specified torque. If the pressure is too tight, the gasket will leak; if it is too tight, it will cause the metal around the screw hole to bulge or screw the screw to cause oil leakage. In addition, if the oil drain plug of the oil pan is not tightened or loosened, it will easily cause the loss of oil, and then the machine damage of “burning and holding the shaft†will occur .3ã€Properly solve all types of oil tanker joint seals. The joint nut of the vehicle is often disassembled and disassembled, and the slide wire is easily broken and loose; the accuracy of the two joints' bell mouth is poor, the center line of the two cones is not coincident and the contact is bad; the taper is different but not consistent, which will cause oil leakage. . Replace the union nut, use a grinding method to solve the cone seal, make the nut tight and solve the seal.
4. If the parts of the tanker are used for too long, there will be excessive wear (such as pistons and cylinders), which will cause the high-pressure gas in the combustion chamber to enter the crankcase and force the oil to leak. Therefore, when the outer cover of the oil filler cover is severe, wear parts should be repaired or replaced as soon as possible.
5, to avoid tanker wheel hub oil. Wheel hub bearings and cavity too much lubricating oil, or its oil package is not properly equipped, poor quality and aging failure; brakes frequently caused by the hub temperature is too high; axle nut loose, etc. will cause the hub to throw oil. Therefore, the "cavity lubrication method (that is, appropriate amount of lubrication)", vacuum suction vehicle to clear the ventilation hole, strict selection of high-quality accessories, and according to the process specification for assembly and high-speed.
6. Replace the failed oil seal in time. Many moving parts (such as oil seals and O-rings) on oil tankers will be improperly installed. The journal and oil seal edges are not the same, and the oil is thrown off by swinging. Some oil seals used for too long will lose their elasticity due to the aging of rubber. Found that leakage should be updated.
7, to avoid the tank valve check valve, vent valve blocked. As a result, the temperature in the enclosure rises, the oil and gas fill the entire space, and the canal is not discharged. As a result, the pressure in the enclosure increases and the lubricant consumption increases and the replacement cycle shortens. After the engine's ventilation system is blocked, the piston's movement resistance is increased and the fuel consumption is increased. Due to the pressure difference between the inside and outside of the enclosure, it often causes oil leakage in the weak sealing area. Therefore, the tanker vehicles need to be checked, dredged and cleaned regularly.
Advantages of smart cabinet locks:
1. Safety: Anti-vibration and anti-prying design, both of which are multiply superior to similar locks.
2. Working mode: adopt the working mode that the door is closed (power off) and locked, and power on (8-24V) is triggered to open instantly. Suitable for additional use of various intelligent signals.
3. Energy saving: the instantaneous power-on opening time is less than 1 second, and the door is closed and locked without power consumption.
4. Specifications: The size and area of a business card (length 93.5mm * 54 width mm), and the thickness is only 13.5mm.
5. Long life: 5 million times of aging test can ensure that the coil will never burn out.
6. Material saving: Ultra-thin design saves raw materials and at the same time provides larger and more flexible space for making cabinets and other objects.
7. Installation method: It can be installed on the wall surface or embedded hidden installation.
8. Commonality: There is no front and back design, all large and small boxes, cabinets and drawers in the left, right, up and down door opening directions can be used in common, which truly realizes one lock for universal use.
9. Status output: There is a lock status output detection signal, which is used to detect the working status of the door (opening, closing).
10. Emergency opening: There are three emergency opening methods hidden in the lock body, so there is no need to damage the cabinet in an emergency.
