Description
Technical field
This utility model relates to a kind of hydraulic system and rinses automatic reverse electric control gear, specifically, relates to one
Plant the electric control gear rinsing simple electric control system replacement human users for hydraulic system secondary.
Background technology
Developing rapidly of current smelting industry, from blast furnace to converter, converter to steel rolling, the deep processing of steel rolling to steel,
A series of engineerings are required for the hydraulic system cooperation to smelting industry, and hydraulic system is shuttled back and forth as human blood
Between each equipment, once hydraulic system breaks down, and may result in the stopping production of equipment, particularly with servo
The requirement of system is the most particularly important, and the most preferably completes hydraulic work system, is that the most each Daye is built
The difficult problem that unit is common.
Hydraulic system secondary backwashing manner needs Non-follow control electromagnetic valve mostly at present, or utilizes mechanical system to make electricity
Magnet valve one direction action, intelligent not, and waste time and energy, preferable developing result can not be reached again, adjusting
During examination there is potential safety hazard etc. in plant equipment.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, it is provided that a kind of more convenient
Hydraulic system rinses automatic reverse electric control gear, and this device can replace the manual operation of conventional personnel, have and save time
Laborsaving, safe and reliable, the advantage such as convenient and swift.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hydraulic system rinses automatic reverse electric control gear, including electromagnetic hydraulic valve, described electromagnetic hydraulic valve
Two ends are connected to the first catalyst and the second catalyst, described first catalyst and the second catalyst respectively with
The normally-closed contact of the time relay is connected with normally opened contact, the both positive and negative polarity of the described time relay respectively with direct current
The connection that the both positive and negative polarity of power supply is corresponding.
Described DC source is the DC source that 220v turns 24v.
Compared with prior art, the technical solution of the utility model is had the benefit that
(1) making simply, cost is relatively low, easy to operate, controls electromagnetic hydraulic valve by electronic devices and components
Duty, it is to avoid operator repeat loaded down with trivial details action.
(2) save hydraulic pressure washing time, improve work efficiency.
(3) working time can be controlled by the time relay according to practical situation, save human users, more
Add safety.
(4) it is widely used, it is adaptable to various hydraulic test secondary oil are rinsed and three oil flushings.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model specific embodiment.
Fig. 2 is automation control circuit schematic diagram.
Reference: 1-electromagnetic hydraulic valve 2-the first catalyst 3-the second catalyst 4-time relay 5-is straight
Stream power supply
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of hydraulic system rinses automatic reverse electric control gear, including electromagnetic hydraulic valve 1, electricity
The two ends of magnetic hydraulic valve 1 are connected to the first catalyst 2 and the second catalyst 3, described first catalyst 2
It is connected with normally-closed contact and the normally opened contact of the time relay 4 respectively with the second catalyst 3, the time relay
The common port of 4 is connected with the positive electrical of 220V power supply, the both positive and negative polarity of the time relay 4 respectively with DC source
The connection that the both positive and negative polarity of 5 is corresponding, wherein the first catalyst 2 and wherein one end of the second catalyst 3 and 220v
Zero line is connected and constitutes loop, and main contacts one end is connected with 24 positive poles.DC source 5 in the present embodiment is 220v
Turning the DC source of 24v, model is SP-500-24；The model of the time relay 4 is FRM02/2；Contact
The model of device is SIEMENS 3TB40, and in specific implementation process, the two or more parallel connection of catalyst also can complete
Corresponding function.
Fig. 2 show the schematic diagram of automation control circuit, wherein: KT is the time relay, KM1 and KM2
All representing catalyst, T is DC source, is carried out the adhesive of control contactor by the Timing of the time relay
To reach the action of electromagnetic valve
This utility model electric control gear realizes the step of Automated condtrol:
1. open the switch of DC source 5.
2. the time relay 4 must conduct, and controls normally opened contact, normally-closed contact and common port by setting the time
Break-make.
3. when the time relay 4 common port is with normally closed connection, the coil of the first catalyst 2 obtains electric, and first connects
Tentaculum 2 main contacts adhesive, one end energized action of electromagnetic hydraulic valve 1；When common port is by the time relay 4
During with normally opened connection, the coil losing electricity of the first catalyst 2, the first catalyst 2 disconnects；Second catalyst 3
Coil obtain electric, the second catalyst 3 main contacts adhesive, the other end energized action of electromagnetic hydraulic valve 1.
4. repeat the action of 3.
Claims (2)
1. hydraulic system rinses an automatic reverse electric control gear, including electromagnetic hydraulic valve, it is characterised in that institute
The two ends stating electromagnetic hydraulic valve are connected to the first catalyst and the second catalyst, described first catalyst and
Two catalysts are connected with normally-closed contact and the normally opened contact of the time relay respectively, and the described time relay is just
The connection that negative pole is corresponding with the both positive and negative polarity of DC source respectively.
A kind of hydraulic system the most according to claim 1 rinses automatic reverse electric control gear, it is characterised in that
Described DC source is the DC source that 220v turns 24v.
