Description

The invention relates to hydraulic devices and can be used in machine tools, industrial robots, agricultural machines and other technological machines with hydraulic drive.

The purpose of the invention is to improve the reliability of the pump by reducing the gas entering it.

The drawing shows a diagram of the pumping station.

The pumping station contains a pump 1 with an inlet 2 and an outlet 3 with nozzles and a degassing chamber 4 with baffle elements 5, with inlet 6 drain 7 and outlet 8 pipelines, the last of which is connected to the inlet nozzle 2, and the degassing chamber 4 is equipped with a level 9 sensor and an ejector 10 is installed on the outlet pipe 8, the active nozzle of which is connected to the outlet pipe 3 of the pump 1 by a retaining pipe 11s on which the valve 12 connected to the sensor 9 is connected, and the inlet pipe 2 is equipped with a booster som 13.

The pumping station operates as follows.

The oil-air mixture enters the inlet pipe 6 of the degassing chamber 4 and spreads successively along the conical fender.

the elements 5 installed in the chamber 4. In the latter, a vacuum is created, as a result of which the air contained in the mixture is removed from the thin layers

on the fender elements 5 through the drainage pipe 7, the working fluid cleared of air is accumulated in the lower part of the chamber 4 and through the exhaust pipe 8 by means of

1 and 13, through the inlet 2 and outlet 3, the nozzles are fed into the hydraulic system of the actuators. When the level of the liquid in the chamber 4 falls below that set in it

Sensor 9 liquid level electric signal is supplied to the opening of valve 12 and the fluid circulates in pump 1 through retaining pipe 11, the hydraulic resistance of which is less than the actuators. Thus, the adverse operating conditions of the hydraulic system of the actuators are eliminated. An ejector 10 and a pump 1–3 installed in the retaining line P create additional liquid support in the suction cavity of the pump 1 i

The presence of valve 12, which is associated with the level of the working H1-ZDOCOSTN cleared of air through a level 9 sensor, prevents the mixture of fluid and air from being supplied to the organs of hydraulic machines. The booster pump 13 sucks the fluid contained in

chamber 4 under vacuum.
