Product Description

STF Series Double Cylinders Return Oil Filter (FST-STF-25L~1300L/min):

Production describle:

Dual-barrel filter, also called double-barrel oil return pipeline filter, is composed of two single-barrel filters and two six-way reversing valves, which have simple structure, convenient use, and a by-pass valve and filter core pollution clogging transmitter to ensure the safety of the system.

The filter is suitable for continuous operation. The hydraulic system oil return pipeline is not allowed to be cleaned when the filter element is shut down. The filter is used to filter the mechanical and chemical impurities in the system and keep the oil flowing back to the tank clean. The filter consists of a two-position six-way directional valve and two return pipeline filters.
Characteristics and working principle:

The double-barrel filter is mainly installed on the return pipeline of the hydraulic system. Various kinds of dirt such as abrasive particles produced by various hydraulic components in the working process can be intercepted by setting the oil filter of the return pipeline to avoid returning to the fuel tank again. Inhaled again by a hydraulic pump. The allowable pressure difference of the oil filter in the return pipeline is 0.3 ~ 0.5mpa. according to the different pressure level.

The accuracy is determined according to the oil contamination requirement. In the working process, when the filter core is clogged to a certain extent and the filter core needs to be cleaned or replaced, it is necessary to stop the mainframe operation to replace the filter element, which is not only a waste of time but also can not meet the needs of continuous operation of the main engine. The double-barrel filter can effectively solve the defect of single-barrel filter and can clean or replace the filter core without stopping to ensure the mainframe work normally and continuously.

When one filter core is blocked and needs to be replaced, it is not necessary to stop the main engine operation. Just open the pressure balance valve and turn the reversing valve. The other filter can take part in the operation and then replace the blocked filter core.

The main performance features are as follows:

1. When a filter core is blocked and the pressure difference between the inlet and outlet reaches 0.35mpa, the transmitter will send out a signal. At this time, the balance valve on the reversing valve should be opened in time, and the reversing valve should be rotated. Turn off the oil of the filter that has blocked the filter, and close the balance valve to keep the backup filter in working condition and keep the system connected. Then replace the blocked filter.

2. When the filter is clogged, no one handles the trouble after the transmitter alarm, and the pressure difference between the inlet and outlet increases to 0.4Mpa, the bypass valve installed in the upper part of the filter will open itself, open the oil circuit, avoid filtering damage, and ensure the system runs as usual.

3. The filter element adopts paper, chemical fiber, mesh and line-gap filter, which can meet the different requirements of the system.

Applications:

1. Metallurgy: used for filtration of rolling mill, continuous casting machine hydraulic system and various lubricating equipment.

2. Petrochemical: separation and recovery of products and intermediate products in refining and chemical production, filtration of oil well water and natural gas.

3.Textile: purification and uniform filtration of polyester melt during drawing, protection and filtration of air compressor, deoiling and dewatering of compressed gas.

4. Electronics and pharmacy: reverse osmosis water, deionized water pre-treatment filtration, washing liquid and glucose pretreatment filtration.

5. Thermal power and nuclear power: gas turbine, boiler lubrication system, speed control system, bypass control system oil purification, feed water pump, fan and dust removal system purification.

6. Processing equipment: paper machinery, mining machinery, injection molding machine and large precision machinery lubrication system and compressed air purification, tobacco processing equipment and spraying equipment filtering.
