Product Description

Construction Machinery 525-9475 Return Oil Filter M31407 M31307 M320 M316 M317 MH3026 M315GC MH3022 MH3024


 

Product Description:

 

The oil return filter element uses high-density fiberglass composite filter material with uniform pore size distribution. The measured retention rate for 6 μ m particles is 95.2%; End cap integrated injection molding to prevent bypass leakage caused by loose threads; The rubber sealing ring has passed the cold and hot alternating test at -40 ℃~120 ℃, and there is no leakage, abnormal noise, or abnormal pressure jump after installation. Last time during continuous operation in the limestone mining area of Shaoxing, Zhejiang, a single SWE600E operated at high frequency for 14 hours a day. After core replacement, the oil cleanliness steadily decreased from NAS level 11 to NAS level 6, and the fluctuation of pilot pressure significantly narrowed, resulting in a more responsive operation. The side of the filter element is laser engraved with a unique traceability code, and the batch can be checked. The moment it is installed, I feel at ease .

 

 

Features:

 

1. Using multi-layer composite glass fiber or stainless steel filter materials, the filtration accuracy is usually 5-20 microns, which can effectively capture pollutants such as metal debris and rubber particles. The single filtration efficiency can reach over 99%, significantly extending the life of hydraulic oil and components.


2. The 20 filter element design has sufficient filtration area, with low resistance when oil passes through. The initial pressure drop usually does not exceed 0.08MPa, ensuring smooth oil return to the system without affecting the efficiency of the main pump and system response speed.


3. When the filter element is clogged and the pressure difference rises to the set value (such as 0.35-0.4MPa), the bypass valve automatically opens, allowing the oil to return directly to the tank without filtration. This is to prevent the filter element from crushing or causing greater damage due to a lack of oil in the system, which is a safety design. However, the filtering function is temporarily disabled when turned on.


4. An optional differential pressure transmitter can be installed. When the differential pressure reaches the warning value (such as 0.2-0.35MPa), an electrical signal or visual prompt (such as a red indicator column popping up) can be sent to remind the operator to replace the filter element in a timely manner and avoid the system being in a bypass state for a long time.

 

5. The filter element with a straight back design is installed at the top of the fuel tank. When replacing, simply unscrew the cover to pull out the old filter element and insert the new one. The operation is simple and not easy to spill oil. Some models are equipped with self sealing valves, which can automatically close the oil tank and oil circuit when the filter element is removed, preventing oil leakage, which is both clean and economical.

FAQ:

Q1.Do you have MOQ?

Depends on different ideas, Can be negotiated.The larger the quantity is, the competitive the unit price will be.

 

Q2.Should the customer pay the delivery fee,How much is it?

For the delivery fee,many samples are be requested to be sent,so we must get delivery fee. If you tell me to use the appointed Express,you will give me your express account or you will pay according to the Express. If you do not request,I will choose a cheap one in China.

 

Q3.How about the after sale service?

1)We will always keep the quality the same as the buyer's samples and if there is something with the quality,we will make compensation for our customers.

2)We will suggest our packing and take charge in our packing,we will keep the goods safe in the delivery.

3)We will trace the goods from the production to selling,we will solve the problems in the selling for our customers.

 

Q4.When can I get a price?

We usually quote within 24 hours after we get your inquiry.

 

Q5: What are the materials of the filter element? What are the corresponding accuracy ranges?

According to the classification of filter materials, there are: oil filter paper: 10-50um, glass fiber: 1-70um, HV glass fiber: 3-40um, metal mesh: 3-500um, sintered felt: 5-70um, and line gap filter: 15-200um.

 

Q6: What brands of filter cartridges do you make?

Our factory produces alternative universal filter elements for foreign brands such as Pall, Hedek, Dasheng, Parker, and Rexroth, as well as national standard oil suction filter elements, oil return filter elements, high-pressure filter elements, and coalescence dehydration filter elements. We support non-standard customization. We welcome samples or drawings for processing and customization.

 

Q7: How can customers choose the appropriate filter size when making their own filters?

We need to provide the flow rate, pressure, external dimensions, accuracy, filter medium and other parameters of the filter designed by the customer. We will provide the customer with the selected filter element size and quantity based on the filter size.

 

Q8: Is there any difference between filtering kerosene, gasoline, diesel filters and general hydraulic oil filters?

The sealing materials used in the filter element are different. Generally, the sealing ring of hydraulic oil filter element is nitrile rubber, while filtering media such as kerosene, gasoline, and diesel requires the use of fluorine rubber rings.
