1. Conditions of use

It is basically the same as the GXYZ type A series, but the viscosity range of the working medium is N22 ~ N460 (equivalent to ISO VG22 ~ 460); in addition, the high pressure and low pressure oil supply pressures of the B series remain unchanged at 31.5MPa and 0.4MPa respectively. Both the flow rate and low-pressure flow rate have increased significantly. Please refer to the technical performance table below for details (the high-pressure flow rate of large specifications is 40L/min, and the low-pressure flow rate is 315L/min).

This device consists of a complete set of oil station, instrument panel, and electric control cabinet (can be controlled by PLC).

The performance parameters and dimensions of this product should comply with the regulations in the table and drawings.

For example, if the B series is used, the high-pressure flow is 20L/min; the high-pressure pressure is 31.5MPa, and the low-pressure oil supply pressure is 0.4MPa; and a high (low) pressure thin oil station with a low-pressure oil supply volume of 100L/min uses relays and contactors Controlled ones are marked as follows: GXYZ-B20/100

3. Structural characteristics

This oil station is an integral type, consisting of a fuel tank, two low-pressure oil pumps, one high-pressure oil pump, two double-cylinder mesh filters, an oil return magnetic mesh filter device, a tube-type oil cooler, various control valves, and pipelines. It is also composed of electric contact pressure gauge, platinum thermal resistor, etc.

The working principle is basically the same as that of the A series; but when the low-pressure oil of the B series is filtered and cooled and supplied externally,Process lubricationA part of the low-pressure oil passes through the bypass and then passes through a double-cylinder filter before entering the suction port of the high-pressure pump to improve the cleanliness level of the high-pressure oil; however, it should be noted that when the actual pressure of the low-pressure oil supply is small (for example, less than 0.2MPa), Since the latter filter also has a pressure difference loss (which also gradually increases over time), in order to ensure the smooth suction of the high-pressure oil pump, the suction port should always ensure positive pressure (this must also be met when the pressure difference before the rear filter is switched is large). requirements); except that the flow rate is very different from that of the A series, the main feature (structural feature) is that there is another filter before the suction port of the high-pressure pump.

Other working principles and operating controls can be found in the A series.
