Abstract
The utility model relates to an overvoltage and undervoltage display device of a pneumatic pressurizing system of a spinning drawing mechanism, comprising a normally-closed pressure switch NC, a normally-closed pressure switch NO and a relay for controlling the starting of a fan; the normally-closed pressure switch NC is serially connected with the normally-closed pressure switch NO and a coil J of the relay for controlling the starting of the fan in sequence and then is connected with the voltage of 220V; the overvoltage and undervoltage display device is characterized in that the normally-closed pressure switch NC and the normally-closed pressure switch NO are respectively connected with an optical display branch in parallel. The optical display branch consists of a resistor and a light-emitting diode which are connected in series. The overvoltage and undervoltage display device has the advantages of being capable of intuitively and fast reflecting the overvoltage and undervoltage of the pneumatic pressurizing system, reducing the workload of maintenance staffs, leading the maintenance staffs to clear faults in time and also having simple structure and low cost.
Description
Technical field
The utility model relates to mistake, the under-voltage display unit of the pneumatic compression system of a kind of spinning, drawing mechanism, also is applicable to other pneumatic compression system.
Background technology
At present, the pneumatic compression system of spinning, drawing mechanism include normally closed pressure switch NC, often open pressure switch NO, control fan starting relay; Normally closed pressure switch NC connects～220V successively with after the coil J of the relay of often opening pressure switch NO, control fan starting connects.Its course of work is as follows: when operating pressure is in when setting value, in the housing of normally closed pressure switch NC, because the active force of its membrane valve equates with admission pressure, make the contact NC1 of normally closed pressure switch NC be in closure state; Regulate the active force of often driving the membrane valve in the pressure switch NO housing by spring, make the contact NO1 that often opens pressure switch NO also be in closure state; At this moment the coil J that controls the relay of fan starting gets electric work, and blower fan normally moves, and complete machine is normally operation also.In case operating pressure surpasses or when being lower than setting value, contact normally closed or that often open pressure switch disconnects, the coil J dead electricity of the relay of control fan starting, and blower fan quits work, and complete machine also quits work.The shortcoming of said system be because do not have, under-voltage display unit, therefore, can not judge the out-of-work reason of complete machine immediately on earth because overvoltage or under-voltage causing, also need further to take other measure to judge, increased workload to the maintenance personal, made the time lengthening of fixing a breakdown.
Summary of the invention
Technical problem to be solved in the utility model provides mistake, the under-voltage display unit of the pneumatic compression system of a kind of spinning, drawing mechanism.
The utility model adopts following technical scheme:
The utility model include normally closed pressure switch NC, often open pressure switch NO, control fan starting relay; Normally closed pressure switch NC connects～220V successively with after the coil J of the relay of often opening pressure switch NO, control fan starting connects; It is characterized in that described normally closed pressure switch NC and Chang Kai pressure switch NO are parallel with light respectively and show branch road.
Described light shows that a route resistance becomes with the light emitting diode string joint group.
Described light shows that branch road is contained in described normally closed pressure switch NC and often opens in the housing of pressure switch NO or outside the housing.
The beneficial effects of the utility model are the mistakes that can reflect pneumatic compression system intuitively, fast, under-voltage, have reduced maintenance personal's workload, and the maintenance personal can in time be fixed a breakdown, and it is simple in structure in addition, cost is low.
Description of drawings
Fig. 1 is the utility model structural representation.
In Fig. 1, NC is normally closed pressure switch, NC1 is the contact of normally closed pressure switch NC, and NO is for often opening pressure switch, and NO1 is for often opening the contact of pressure switch, 1. the air inlet of normally closed pressure switch NC, 2. the housing of normally closed pressure switch NC, the 3. spring of its membrane valve of control of normally closed pressure switch NC is 4. often opened the air inlet of pressure switch NO, 5. often open the housing of pressure switch NO, 6. often open the spring of its membrane valve of control of pressure switch NO.
The specific embodiment
By embodiment shown in Figure 11 as can be known, it by normally closed pressure switch NC, often open pressure switch NO, control fan starting relay form; In the housing 2 of normally closed pressure switch NC, resistance R 1 and the two ends that are attempted by contact NC1 after LED 1 is connected, whether LED 1 is positioned at the groove on the sidewall of housing 2 of normally closed pressure switch NC, so that watch it luminous.
In the housing 5 of often opening pressure switch NO, resistance R 2 and the two ends that are attempted by contact NO1 after LED 2 is connected, the installation method of LED 2 is identical with the installation method of LED1.
Normally closed pressure switch NC, the coil J of relay that often opens pressure switch NO and control fan starting connect～220V after connecting successively.
The course of work of present embodiment is as follows:
NC1 disconnects when operating pressure surpasses setting value, the J dead electricity, and blower fan quits work, and complete machine quits work, and LED1 is bright, the indication overvoltage protection; NO1 disconnects when operating pressure is lower than setting value, the J dead electricity, and blower fan quits work, and complete machine quits work, and LED2 is bright, the indication under-voltage protection.
In the present embodiment, light shows that branch road also can adopt other light source; In addition, light shows that branch road also can be installed in outside normally closed and that often open the housing of pressure switch.
Claims (3)
1, the mistake of the pneumatic compression system of spinning, drawing mechanism, under-voltage display unit, it include normally closed pressure switch NC, often open pressure switch NO, control fan starting relay; Normally closed pressure switch NC connects～220V successively with after the coil J of the relay of often opening pressure switch NO, control fan starting connects; It is characterized in that described normally closed pressure switch NC and Chang Kai pressure switch NO are parallel with light respectively and show branch road.
