4) Then connect the intake/compression pipe of the tank car to the Rotary blades vacuum pump tightening it to the adjustable elbow
using metal clamping bands in relation to the diameter of the pipe.
3.5 HYDRAULIC MOTOR INSTALLATION INSTRUCTION
Make sure take the rotation of the unidirectional motor is the proper are for your system. Make sure take this is a good linear
matching between motor shift and power take off.
TANK. Tank capacity must be sufficient for the system’s operating conditions ( ~ 3 times the amount of oil in circulation) to avoid
overheating of the fluid. A heat exchanger should be installed if necessary. The intake and return lines in the tank must be spaced
apart (by inserting a vertical divider) to prevent the return-line oil from being taken up again immediately.
LINES. The lines must have a major diameter which is at least as large as the diameter of motor or pump ports, and must be perfectly
sealed. To reduce loss of load, the lines should be as short as possible, reducing the sources of hydraulic resistance (elbow, throttling,
gate valves, etc.) to a minimum. A length of flexible tubing is recommended to reduce the transmission of vibrations. All return lines
must end below the minimum oil level, to prevent foaming. Before connecting the lines, remove any plugs and make sure that the
lines are perfectly clean.
FILTERS. We recommend filtering the entire system flow rate. Filters should be fitted as indicated in the first pages of the catalogue.
Only coarse filters are recommended for pump intake.
HYDRAULIC FLUID. Use hydraulic fluid conforming to ISO/DIN standards, having viscosity as specified in the first pages of the
catalogue. Avoid using mixtures of different oils which could result in decomposition and reduction of the oil’s lubricating power.
