I. Basic Overview of BZL262-270 Product
In industrial production, places such as power plants, chemical plants, and coal mines often have flammable and explosive gases. The insulating oil and hydraulic oil used in equipment will absorb water, mix in metal impurities and air over a long period of use, which directly affects the operating condition of the equipment and also poses safety hazards. Ordinary oil filtering equipment lacks explosion-proof protection structures and cannot be used in high-risk areas. The BZL262-270 explosion-proof vacuum oil filter machine is based on mature purification technology and is suitable for small and medium-sized oil processing scenarios.
The model belongs to the BZL explosion-proof oil filtering series. The numerical parameters correspond to the equipment's processing flow, vacuum chamber size, and explosion-proof supporting configuration. The entire machine is processed according to the explosion-proof electrical standard, and the motor, heating components, and control elements are all sealed and explosion-proof treated. It can be adapted to various explosion-proof controlled factory areas for use. The equipment purifies the oil through a physical process of vacuum dehydration and degassing combined with multiple layers of filtration. No chemical additives are added, which can improve the condition of contaminated oil, extend the oil's service life, and reduce the expenses associated with waste oil treatment.
II. Overall Structure and Working Process of BZL262-270
The equipment adopts a modular combination structure, mainly divided into explosion-proof power components, vacuum separation chambers, multi-stage filtration units, constant temperature heating devices, and intelligent protection control systems. Each module is independently assembled, and the disassembly and maintenance operations are simple. It is suitable for the limited installation space in factory areas.
The explosion-proof power components include explosion-proof vacuum pumps and oil pumps. The motor is equipped with a thickened explosion-proof housing and a sealed wiring box. The equipment is fully grounded to avoid static electricity and electric sparks. The vacuum pump continuously extracts the air inside the chamber to form a negative pressure environment, and the oil pump can adjust the flow rate. When dealing with severely emulsified oil, the flow rate can be reduced to prolong the oil separation time. The wear-resistant coating inside the pump body can cope with contaminated oil containing metal particles for a long time.
The vacuum separation chamber is the core of purification. The internal atomization structure disperses the oil into thin oil films. Under negative pressure, the water in the oil quickly vaporizes, and the water vapor is collected through a condensation device, not mixing back into the purified oil. The chamber is equipped with an explosion-proof observation window, allowing staff to check the oil-water separation situation without stopping the machine. The chamber plates are treated with anti-corrosion treatment, and long-term processing of oily water-containing oil does not easily cause leakage or rust. The multi-stage filtration unit is divided into four layers: coarse filtration, permanent magnet adsorption, intermediate filtration, and precision filtration. Different particle sizes of pollutants are intercepted layer by layer. The coarse filter blocks large impurities, the permanent magnet module adsorbs iron filings, the intermediate filter removes suspended colloids, and the end filter retains fine particles. The filter elements adopt a quick-release clamping structure, are easy to replace, and come with various specifications of consumables, allowing for flexible selection based on the type of oil to be processed.
The constant temperature heating device is equipped with sealed explosion-proof heating tubes and temperature sensing probes. It moderately reduces the viscosity of the oil to assist in breaking the oil-water emulsion layer. The equipment has an over-temperature power-off protection, and an insulation layer is added to the outer layer of the heating area to reduce heat loss and lower the surface temperature of the machine body. The control system integrates multiple interlocks such as liquid level, pressure, and overload, automatically adjusting or stopping the machine when parameters are abnormal. After setting the basic parameters, it can operate autonomously for a long time, reducing the time for manual supervision.
III. Characteristics of BZL262-270 Equipment Usage
All components of the entire machine are designed with explosion-proof features. The chambers and pipelines are uniformly grounded to prevent static electricity, and there are no exposed hot or electrified components. It meets the usage specifications for dangerous areas such as underground, substation maintenance areas, and oil storage areas. The applicable scenarios cover various industrial and mining industries.
The physical purification process does not change the original components of the oil. After repeated filtration, the moisture and gas content of the oil significantly decrease, improving lubrication and insulation effects, and reducing the probability of equipment rusting, wear, and failure. The modular body has a moderate weight, facilitating disassembly and transportation. The filter elements, seals, and other easily damaged parts have standardized specifications. The maintenance personnel in the factory can complete the replacement, drainage, and other maintenance tasks after simple training, reducing the equipment downtime.
One device can handle various media such as transformer insulating oil, turbine oil, mining machinery lubricating oil, and industrial hydraulic oil. Changing the oil only requires adjusting the temperature and negative pressure values, and no additional dedicated equipment needs to be purchased, saving space and procurement costs.
V. Main Applicable Industry Scenarios
Power substations and power plants' internal transformers continuously produce contaminated insulating oil, and there is oil vaporization in the maintenance area. The BZL262-270 can perform online circulating oil filtration. During major maintenance, the waste oil in the storage tank can be centrally treated, and the purified oil can be re-added and used, reducing the purchase of new oil.
Oil fields and refining plant areas have a large amount of flammable volatile media. Various hydraulic oils and lubricating oils of various units are prone to impurities and emulsification. This model's explosion-proof attribute meets the safety requirements of the factory area, and the waste oil from the equipment is processed in different areas, reducing the frequency of hazardous waste transportation.
In underground coal mines, the chamber humidity is high and the coal dust is abundant. The hydraulic supports and mining equipment use oil that is prone to contamination. Underground electrical equipment has explosion-proof requirements. This equipment can be transported to underground operations, and the waste oil can also be centrally purified and recycled in the ground workshop, controlling the daily oil cost.
In addition, heavy machinery processing workshops, port crane equipment maintenance, and ship engine rooms can also be used in combination to cope with high-humidity and volatile medium working conditions and complete daily oil purification operations.
VI. Basic Operations and Daily Maintenance Key Points
Before starting, check the grounding lines and pipeline sealing conditions, confirm that the filter elements are installed properly and the drainage valves are closed, set the appropriate oil temperature and vacuum degree, start the vacuum pump to pre-pump the cavity, then start the oil pump to carry out purification, and take samples for oil quality testing at regular intervals. After the operation, first turn off the heating system, cool the oil, then shut down the oil pump and vacuum pump, open the drainage port to discharge water and oil sludge, and wipe the oil stains on the body.
After each use, clean the coarse filter screen, check for leakage in the pipeline; calibrate the temperature and pressure sensing elements weekly, clean the dust cover of the vacuum pump; replace the saturated filter element monthly, tighten the pipeline bolts, test the protection interlock function of the entire machine; for long-term shutdown, empty the cavity and pipeline residual oil, store it in a dry and ventilated area to avoid oil sludge blocking the pipeline.
Standard operations and regular maintenance can stabilize the equipment's purification capacity, extend the overall machine's service life, and balance the safety production, stable operation of the equipment, and environmental control requirements of the factory area. This is also the main reason why this model is widely used in various industrial and mining sites.
