(1) Oil and gas recovery valve: The Dongfeng tanker's oil and gas recovery valve is a device that recovers the oil and gas generated during the loading and unloading of oil. It can be installed directly on the top tank of the tanker or on the manhole cover. In the above, the mechanical linkage opening can be realized by a push rod and the bottom valve of the tank bottom, and the opening and closing of the gas can also be controlled by the gas source. (2) Oil and gas recovery joints: The oil and gas recovery system of oil companies' oil depots consists of fire-breathing breathing valves, pipeline flame arrestors, three-way floating ball valves, oil and gas recovery joints, oil and gas recovery quick joints, etc., and forms a closed loop with tanker oil and gas recovery systems. The system effectively recycles the oil and gas generated during the refueling process at the station to avoid the proliferation of oil and gas. (3) Subsea valve: The bottom valve of the Dongfeng Tanker, also called the emergency shut-off valve of the tank truck, is installed at the bottom of the tank and used for down loading and refueling. It is easy to operate, saves time, and is safe and environmentally friendly. Pressure balanced subsea valves are used for multi-tank tank trucks, which allow separate loading and unloading of different tanks. The three-way design simplifies the piping, reduces the load, and is simple to operate, safe and reliable. (4) Bottom-mounted valve: The bottom-mounted valve of Dongfeng Tanker, also known as the unloading valve or under-loading oil, is installed under the side of the tanker for quick unloading. (5) Anti-overflow probe: The anti-overflow electronic sensor is a kind of safety device that is used to prevent the liquid from leaking out of the container when the container is filled with liquid. It is installed on the top of the container tank. On the manhole cover, when the oil level reaches the warning limit, the sensor will automatically alarm to break the brake. (6) European standard can lid: also known as manhole cover, installed on top of oil tanker tank, with built-in breathing and emergency exhaust function, and can be installed in the manhole cover oil and gas recovery valve, oil hole, anti- Overflow probes, etc., anti-overflow sensing system In the process of loading oil, when the liquid level reaches the detection position, the sensing system will automatically alarm to stop the loading of oil. The built-in breathing valve keeps the internal pressure of the oil tank stable during the oil transportation and balances with the external pressure. The design of the dumping overflow prevents the tank truck from being sealed in the event of an accident and the pressure of the emergency exhaust device in the tank. In the case of a sharp increase, it will be automatically opened to release the pressure inside the tank, thereby preventing accidents and greatly improving the safety of oil transport. (7) Tanker: Dongfeng Dooligo tanker truck is equipped with a dedicated tanker, is a new large flow tanker, bold 15 meters automatic return reel with gun.
Overview: Honing is to use the honing head honing workpiece and finishing on the surface of the grinding machine. It is mainly used in automobile, tractor, hydraulic parts,
bearing, aviation and other manufacturing industries to honing the workpiece
hole. Honing Machine has vertical and horizontal two kinds.
Our company main product Vertical Honing Machine(half automatic and CNC ) and Horizontal honing machine.
1.vertical honing machine spindle working travel shorter, suitable for honing cylinder body and casing hole, etc.With oil stone Mosaic honing head driven by the placement of the vertical spindle rotation, at the same time in hydraulic device driver operating vertical reciprocating feed movement.(see picture)
2.Horizontal honing machine work schedule long, suitable for deep hole honing, depth of up to 3000 mm.The placement of horizontal honing head not rotating, axial reciprocating motion, workpiece by the spindle drive rotation, for lathe bed in the middle of the workpiece at the center of the frame and the supporting honing rod guide frame.In the machining process, the honing head oil stone in swell-shrink institutions operating radial feed, the workpiece processing step by step to the required size.A new type of honing machine adopts hydraulic swell-shrink honing head.Most of honing machine is semi-automatic, often with automatic measuring device, can also be incorporated in the automatic production line of work.In addition to processing hole honing conversion, processing and other surface of the cylindrical honing machine, bearing raceway honing machine, flat honing machine and surface honing machine, etc.(see picture )
Operation requirements
1.Honing machine operation has a certain technology, need a understand technical person, this person should be trained about grinding safe operating methods.And make necessary preparation before operation can be carried out
2.Check the lubrication part of the honing machine, especially the gearbox, see if there were any lubricating oil.If there is no oil, to all the oil injection hole filling.
3.Check coolant cleaner.If insufficient cooling fluid, coolant will be listed.Coolant to regular cleaning, not allowed to use a squalid coolant.
Continuous work two months later, the need for an oil change.Under normal circumstances, in the first quarter in oil at a time.The hydraulic oil 20 # engine oil should be adopted in general.An oil change, need to use kerosene oil filter and oil tank cleaning.
4.After the machine is idle for a period of time, in order to discharge the air in the hydraulic line, and check the work of each part is normal.
Machine with hydraulic oil temperature, generally does not allow more than 60 ℃, the highest must not exceed 65 ℃, otherwise the cooling measures should be taken or stop working.
5.Check the sharpening stone size is correct, whether the honing head increases and flexible, fastening oilstone seat spring is strong.
6.Adjust spindle rotation and reciprocating motion, make it meet the requirements of the process specification.
7.Measuring tool ready, and check the door of the work is normal, the precision of measuring whether or not up to standard.
8.Need to check in accordance with the requirements in place to ensure the personal safety and honing machine work in place.
