Uninterrupted automatic liquid level controller

Abstract

The invention discloses an uninterrupted automatic liquid level controller. The uninterrupted automatic liquid level controller comprises a floating ball, a connecting shaft and a hydraulic pump. The uninterrupted automatic liquid level controller is characterized by further comprising a gear, a toothrow, a potentiometer and a frequency converter. The connecting shaft is connected to the top of the floating ball. The toothrow is installed on the top of the connecting shaft. A toothrow surface is arranged on the toothrow in the vertical direction. The gear is arranged next to the toothrow. The toothrow surface of the toothrow is meshed with a tooth surface of the gear. The potentiometer which is used for measuring the rotation angle of the gear is arranged on the gear. The potentiometer is connected with the frequency converter. The frequency converter is connected with a motor of the hydraulic pump through a signal line. The uninterrupted automatic liquid level controller solves the problems in the prior art that the motor of the hydraulic pump needs starting frequently, energy consumption is high, the hydraulic pump can be in a non-load state, and the hydraulic pump is easily damaged; the uninterrupted automatic liquid level controller has the advantages of being simple in structure, reducing the energy consumption due to the fact that the motor is free of the non-load state, being capable of accurately controlling liquid level, and keeping the liquid level constant.

Description

technical field [0001] The invention relates to a liquid level controller, in particular to an uninterrupted liquid level controller. Background technique [0002] The floating ball of the liquid level controller uses the buoyancy of the liquid to change its position according to the position of the liquid. When the hydraulic pump pumps oil, it controls the work of the hydraulic pump through the liquid level controller. The traditional pumping is controlled by the jog mode. When the floating ball is at a high position, it means that the liquid level in the container is at a high level, and the hydraulic pump motor rotates to drive oil pumping. When the floating ball is at a low position, the hydraulic pump motor stops rotating. There are the following disadvantages in adopting the above method: 1. The floating ball is changed between high and low positions, and the hydraulic pump motor needs to be started frequently, which consumes a lot of energy when starting, consumes a l...

AI Technical Summary

Problems solved by technology

The above method has the following disadvantages: 1. The floating ball changes between high and low positions, and the hydraulic pump motor needs to be started frequently, which consumes a lot of energy when starting, consumes a lot of electric energy, and is expensive to use.

2. The hydraulic pump motor needs to be started frequently. Due to the high energy consumption during startup, the hydraulic pump motor may be burned out, which will bring great losses to the enterprise

3. The hydraulic pump seals are damaged and accelerated due to the frequent stop-start of the pump, resulting in poor airtightness and abnormal dry running

4. The liquid level fluctuates up and down, and the control accuracy is low
