Abstract
The utility model discloses a liquid level control system of a thickener hydraulic system, which comprises an oil tank, a controller, a warning lamp, and a relay connected to a power supply loop of the hydraulic system, wherein a liquid level sensor is mounted on the inner wall of the oil tank, and is electrically connected with the signal input end of the controller; the signal output end of the controller is electrically connected with the relay and the warning lamp respectively. According to the utility model, the structure is reasonable; when the liquid level sensor feeds back a liquid level signal inside the oil tank to a PLC, if the liquid level is too low, the PLC gives an instruction to the relay, the power of the hydraulic system is turned off, and the warning lamp flickers to remind operators, so as to avoid damage to the oil pump caused by the too low liquid level, and guarantee the safe operation of the oil pump.
Description
Technical field
The utility model relates to the thickener field, specifically a kind of tank level control system of thickener hydraulic system.
Background technology
At industry-by-industry tail muddy water such as coal, metallurgy, chemical industry, environmental protection, process on this link, be mainly used in thickener concentrated and clarification and become one of key equipment of extensive use, its be mainly utilize sedimentation theory that the solid particle in ore pulp is deposited to the pond of thickener at the bottom of, clarified solution is gone out from the downflow weir overflow, to realize Separation of Solid and Liquid.
In the thickener total, hydraulic electric control is the core of controlling thickener work, in Hydraulic Station, liquid level is observed and is adopted oily window always, having relatively high expectations to equipment point-detecting like this, the management of some equipment does not catch up with, and spot check do not accomplish, in fuel tank, hydraulic oil is not found lower than alarm liquid level, the in-line of hydraulic pressure entrained air likely just, cause larger damage to oil pump like this.
The utility model content
The purpose of this utility model is to provide a kind of tank level control system of thickener hydraulic system, avoids the too low damage that oil pump is caused of liquid level.
The technical solution of the utility model is as follows:
A kind of tank level control system of thickener hydraulic system, include fuel tank, controller, warning light and be connected to the relay in the HPS loop, it is characterized in that: on the inwall of described fuel tank, liquid level sensor is installed, described liquid level sensor is electrically connected to the signal input part of controller, and the signal output part of described controller is electrically connected to relay and warning light respectively.
The tank level control system of described thickener hydraulic system is characterized in that: described controller is PLC.
The beneficial effects of the utility model:
The utility model is rational in infrastructure, liquid level sensor feeds back to PLC by the liquid level signal in fuel tank, if liquid level is too low, PLC sends instruction to relay, the hydraulic system outage, the warning light flicker, remind operating personnel, avoid damage oil pump caused because liquid level is too low, guaranteed the trouble free service of oil pump.
The accompanying drawing explanation
Fig. 1 is the utility model structure principle chart.
The specific embodiment
Referring to Fig. 1, a kind of tank level control system of thickener hydraulic system, include fuel tank, controller 2, warning light 4 and be connected to the relay 3 in the HPS loop, liquid level sensor 1 is installed on the inwall of fuel tank, liquid level sensor 1 is electrically connected to the signal input part of controller 2, and the signal output part of controller 2 is electrically connected to relay 3 and warning light 4 respectively.
In the utility model, controller 2 is PLC.
Claims (2)
1. the tank level control system of a thickener hydraulic system, include fuel tank, controller, warning light and be connected to the relay in the HPS loop, it is characterized in that: on the inwall of described fuel tank, liquid level sensor is installed, described liquid level sensor is electrically connected to the signal input part of controller, and the signal output part of described controller is electrically connected to relay and warning light respectively.
2. the tank level control system of thickener hydraulic system according to claim 1, it is characterized in that: described controller is PLC.
