1. Conditions of use

This product is suitable for thin oil lubrication systems with a nominal pressure of 0.6 MPa. It has the function of removing impurities in the lubricating oil and making the oil supplied to the lubrication points clean. The small one is an integral type, and the larger one is a combined type. Each one consists of two It consists of a set of filter cartridges and a three-position six-way reversing valve. During operation, one cartridge is working and the other is in standby. The filter cartridges can be switched without stopping to achieve the purpose of uninterrupted operation of the circulating lubrication system.

6. Working principle

1. This type of filter consists of a six-way reversing valve and two sets of filtering devices, which are placed at the outlet of the oil pump and the front end of the cooler. During normal operation, one set of filtering devices is activated and the other set is closed by the reversing valve for standby.

2. The valve-type six-way reversing valve is manual. During the working process, the backup filtering device is cut off and connected to the working filtering device.Process lubricationThere are pass and stop marks on the upper part of the valve, and the direction can be changed without stopping when the working pressure is ≤6kgf/cm2.

3. The filtering device is divided into two groups, one is working and the other is standby. When the filter device needs maintenance and cleaning during operation, another set of backup filter devices can be started to work without affecting the normal operation of the host machine.

7. Instructions for use

1. When the pressure difference between the inlet and outlet of the filter is ≥0.5kgf/cm2, it means that the filter element in the filter device has been blocked by mechanical impurities. The filter element should be cleaned or replaced in time, and the cylinder should also be cleaned.

2. During normal operation, the pressure difference between the inlet and outlet of the filter should be ≤0.035MPa.

8. Ordering Instructions

The required filtration precision value must be indicated when ordering. If not specified, it will be supplied as 0.12mm.
