1. Conditions of use

This product is suitable for thin oil circulation lubrication systems of large equipment such as mills and rotary kilns equipped with double sliding shoe dynamic and static pressure bearings. The viscosity grade of the working medium is N22

~N460 (equivalent to ISOV G22~460) various industrial lubricants; if the low-pressure pump oil volume is divided into two oil supply pipelines, a set of dual high-pressure high (low) pressure diluents can be used

The oil station replaces two ordinary high (low) pressure thin oil stations [such as the smaller of the GXYZ type A series high (low) pressure thin oil stations].

According to the working principle of dynamic and static pressure lubrication, a high-pressure system is used during startup, low speed and parking, and a low-pressure system is used during normal operation to ensure that large machinery operates under various conditions.

Reliable performance can be obtained at any speedProcess lubricationto extend the life of the host.

The pressure of the two high-pressure output pipelines of the dilute oil station is both 31.5MPa, and the flow rate is 2.5L/min. The pressure of the low-pressure part is 0.4MPa, and the low-pressure flow rate is 16~

100L/min; the thin oil station has filtration, cooling, heating and other devices as well as interlocking, alarm, automatic control and other functions.

The performance parameters and dimensions of this product should comply with the regulations in the table and drawings; this device consists of a complete set of oil station, instrument panel and electric control cabinet (can be controlled by PLC).

3. Working principle and structural characteristics

The main feature of the double high-pressure and high (low) pressure thin oil station is that one set of thin oil stations has two high-pressure output pipelines, which can meet the needs of two high-pressure lubrication points. The other features are the same as ordinary high (low) pressure thin oil stations.

Each high-pressure output pipeline is equipped with a pressure gauge and a pressure controller to control the pressure of each high-pressure pipeline and observe the working conditions.

The components of this product are also the same as those of ordinary high (low) pressure thin oil stations; it only has one more high-pressure oil pump, and the suction ports of the two high-pressure oil pumps are connected to the oil supply ports of the low-pressure pumps; when both high-pressure pumps are started, It is necessary to suck 5L/min of lubricating oil from the low-pressure oil supply port. For those with a small flow rate of the low-pressure pump, the low-pressure oil supply pressure may be reduced when starting the high-pressure pump. For systems where the lubricating oil is supplied to the same bearing, The total amount of lubricating oil in the bearings has not been reduced and will not affect the lubrication of the bearings; however, when the high-pressure pump is started, the reduction in low-pressure pressure may cause the backup low-pressure pump to be temporarily started. This situation will not affect the normal operation of the lubrication system; however, When using the standby working mode in which two low-pressure pumps switch to each other, the lubrication system may not be able to work normally if the flow rate of the standby pump still does not meet the requirements after the working pump stops. Therefore, attention should be paid to this situation when selecting a low-pressure pump with a smaller flow rate.
