INTRODUCTION

The LY series plate and frame pressure oil filter machines have a compact and reasonable structure. The main frame is made of high-quality metal materials that are sturdy and durable, with good pressure resistance, enabling them to adapt to relatively high filtration pressures. The outer shell has undergone anti-corrosion treatment and can cope with complex industrial environments.

The core component, the plate and frame device, is ingeniously designed. The filter plates and frames cooperate with each other and form a sealed filtration space when pressed tightly. Different specifications of filter cloths can be installed as required to meet diverse filtration accuracy needs. This structure allows the oil to fully contact the filter cloth under pressure, achieving effective interception of impurities. The equipment is easy to operate. The filtration process can be adjusted simply through valve control, and it is equipped with a visual window for convenient real-time observation of the filtration status. It has strong universality and is suitable for the filtration and purification of various oil products.

ANALYSIS OF THE CORE WORKING PRINCIPLE

Feeding and Pressurizing Stage

The oil is first delivered to the feed port of the plate and frame pressure oil filter machine and enters the filtration chambers composed of filter plates and frames. Subsequently, a certain pressure is applied through an external pressurizing device, so that the oil evenly passes through the filter cloth under the drive of pressure and starts the filtration process. This pressure can ensure that the oil fully contacts the filter cloth, prompting impurities to be intercepted on one side of the filter cloth while the filtered oil flows to the other side through the filter cloth. 

Filtration and Separation Stage

When the oil flows through the filter cloth, relying on the fine pore structure of the filter cloth, large particle impurities, as well as some colloids and suspended substances, are directly intercepted, achieving separation from the oil. As the filtration continues, impurities gradually accumulate on the surface of the filter cloth, while pure oil continuously permeates through, achieving the purpose of purifying the oil.

Slag Discharge and Cleaning Stage

When the filtration progresses to a certain extent and the excessive accumulation of impurities on the surface of the filter cloth affects the filtration effect, the feeding can be stopped, the plate and frame can be loosened, the impurity slag on the filter cloth can be discharged, and then the filter cloth and the plate and frame can be cleaned so that they can be put into use again, ensuring that the equipment can continuously and efficiently carry out oil filtration work.

TECHNICAL PARAMETERS

Filtration Accuracy

The LY series plate and frame pressure oil filter machines have a relatively wide filtration accuracy range, between 5 microns and 100 microns, which can meet different requirements for the purity of oil products in different industrial scenarios. For fields with extremely high requirements for oil cleanliness, such as electronic equipment manufacturing and lubrication of precision instruments, a high-precision configuration of 5 - 10 microns can be selected to accurately remove tiny particulate impurities in the oil and ensure the stable operation of the equipment. For general industrial equipment, such as ordinary machine tools and small construction machinery, a filtration accuracy of 30 - 100 microns is sufficient to meet the basic oil filtration needs while taking into account the filtering efficiency and cost control.

Flow Rate Range

The flow rate range of the equipment fully considers the oil usage in actual production. The minimum flow rate can be as low as 10 liters per hour, which is suitable for small equipment maintenance and fine processing scenarios where the oil consumption is low but the requirement for filtration accuracy is high, such as small laboratory equipment and the lubrication systems of precision electronic equipment. The maximum flow rate can reach 500 liters per hour, mainly targeting situations where equipment is relatively concentrated in some small and medium-sized industrial production workshops and needs to complete oil filtration in a timely manner, such as small mechanical processing factories and auto repair workshops, so as to ensure that the oil can be filtered and supplied to the equipment in a suitable time and avoid affecting the normal production or equipment operation.

Working Pressure

The normal working pressure interval of this series of filter machines is set between 0.3 MPa and 1.2 MPa. Within this pressure range, the equipment can operate stably to ensure that the oil can smoothly pass through the plate and frame filtration system for impurity removal. The reasonable pressure design not only ensures the smooth progress of the filtration process but also prevents damage to the plate and frame, filter cloth and other filtering components due to excessive pressure, extending the service life of the equipment. For some special high-pressure application scenarios, some models that have undergone special strengthening treatment can withstand a maximum working pressure of up to 1.5 MPa, meeting the pressure requirements for oil filtration under special circumstances.

Plate and Frame Dimensions and Quantity

The LY series plate and frame pressure oil filter machines provide a variety of plate and frame dimensions for users to choose from. Common plate and frame outer dimensions include specifications with side lengths of 300 mm, 400 mm, and 500 mm, etc. The number of plates and frames can also be flexibly configured according to the actual filtration requirements, ranging from several to dozens. Different combinations of plate and frame dimensions and quantities can adjust the filtration area, thereby meeting different scales of oil filtration tasks. Whether it is small-scale fine oil treatment or large-scale batch filtration, efficient adaptation can be achieved.

Filter Cloth Material and Specification

As a key filtering medium, the filter cloth has a variety of materials and specifications available for selection. In terms of materials, it covers different types such as polyester fiber, polypropylene, and cotton. Each material has different chemical stability, temperature resistance, and filtering characteristics. For example, polyester fiber filter cloth has high strength and good chemical corrosion resistance and is suitable for a variety of oil products. Cotton filter cloth has good adsorption properties and is often used in some oil filtration scenarios with high requirements for impurity adsorption. In terms of specifications, there are different weaving densities and thicknesses. Appropriate filter cloth can be selected according to specific filtration accuracy and oil product characteristics to achieve the best filtration effect.

Applicable Oil Temperature Range

Considering the temperature differences of oil products in different industrial environments, the LY series plate and frame pressure oil filter machines have a relatively wide applicable oil temperature range and can usually work normally under the oil temperature conditions between -10°C and 120°C. This means that whether it is in the cold outdoor working environment in winter or in the high-temperature indoor production workshop, it can effectively filter the oil without the performance and filtering effect of the equipment being affected by changes in oil temperature, further enhancing the adaptability and universality of the equipment.

Selection Points and Applicable Scenarios

Selection Based on Oil Product Characteristics

Different oil products have different characteristics in terms of chemical composition, viscosity, and impurity types. When selecting the LY series plate and frame pressure oil filter machines, these factors should be fully considered. For example, for high-viscosity oil products, it is necessary to choose equipment with a larger filtration area and higher pressure tolerance to ensure that the oil can smoothly pass through the filtration system. For oil products with special types of impurities, such as those containing more colloids, it is necessary to select a filter cloth material with good adsorption properties to match it and improve the filtration effect.

Selection Based on Flow Rate Requirements

The flow rate requirements of equipment for oil in various industrial scenarios vary greatly, which is one of the key considerations in the selection process. In scenarios where small equipment is concentrated and the total oil consumption is not large, such as small electronics factories and handicraft workshops, it is advisable to choose models of oil filter machines with a smaller flow rate and a relatively small number of plates and frames to avoid resource waste and accurately meet the filtering needs. For places where the oil consumption is relatively large and needs to be filtered in a timely manner, such as auto repair shops and small mechanical processing workshops, models with a larger flow rate and a larger number of plates and frames should be selected to ensure the timeliness of oil supply.

Consideration of Working Environment Factors

The complex industrial environment requires that environmental factors be fully considered when selecting equipment. If the working environment has a lot of dust, corrosive gases, and other situations, such as chemical workshops and open-pit mines, it is necessary to choose oil filter machines with good corrosion resistance and dustproof capabilities of the outer shell and internal components to ensure that the equipment can operate stably for a long time. In high-temperature or low-temperature environments, like high-temperature forging workshops or cold outdoor construction sites, it is necessary to choose models that can adapt to the corresponding temperature ranges to ensure that the filtering work will not be affected by temperature.
