Precision volumetric vacuum automatic oiling equipment

Abstract

The invention discloses a precision volumetric vacuum automatic oiling equipment, which comprises a vacuum degassing tank, a feeding pump, an automatic vacuum chamber, a vacuum pump group and a PLC controller. A liquid level sensor and a vacuum pump are installed on the side wall of the vacuum degassing tank. The groups are respectively connected with the vacuum degassing tank and the automatic vacuum chamber. The feed pump is installed on the side wall of the vacuum degassing tank. The oil supply port formed at the bottom of the feed pump is connected with the input port of the metering cylinder through the oil supply pipeline. The metering cylinder The output port of the precision filter is connected with the inlet of the precision filter, and the outlet of the precision filter is connected with the inlet of the oil injection valve; the oil injection valve is installed above the automatic vacuum chamber, and the outlet of the oil injection valve is located in the automatic vacuum chamber; a servo motor is installed above the metering cylinder, controlled by PLC The controller is respectively connected with the vacuum pump group, the servo motor and the oil injection valve through signal lines. The invention makes the oiling precision reach ±0.25g, improves the oiling precision and precision stability, and realizes that the vacuum degree of oiling can be adjusted within the range of 1-30Pa according to the technical requirements.

Description

technical field [0001] The invention belongs to an oil injection device, in particular to a precision volume vacuum automatic oil injection device. Background technique [0002] With the upgrading of the series of special high-speed equipment, the first-generation vacuum oiling equipment matched with it can no longer fully meet the actual needs of the special equipment for the oiling process: oiling accuracy, oiling production capacity, and the working range of oiling vacuum degree.
