Description:

Productoverview:

ZW-UQK series Anti float level controller Through the magnetic induction induction to achieve level, level role. The floating ball is equipped with a magnet, and the plastic float level switch body with the reed or reed switch, dry reed pipe connected with the two lines, usually removed in the plastic body or body is 350MM stainless steel. The dry reed pipe of high temperature or low temperature white black adhesive glue injected in the body. It is a simple and practical liquid level control switch. According to the installation of the form can be divided into the side mounted type (side mounted horizontally) and top loading type (vertical installation).

Two, work principle:

ZW-UQK series of anti float level controller is composed of a floating ball assembly and transformation of two parts. When the measured level changes, the floating ball will move up and down, to the end of the connecting rod magnet do the opposite direction. Reach level two control points, through the magnetic repulsion of the marine float level controller is the conversion mechanism of the magnetic steel quickly rejected to the other side, the micro switch is turned on or off, the switch signal output, to achieve the alarm or automatic control for marine float level controller.

Three, application:

ZW-UQK series anti float level controller is composed of isolated group Fuqiu and micro switch group is composed of two parts. Float level switch is widely used in electronics, electric power, chemical industry, water treatment, drainage and other industries to the liquid level control and alarm. With a self-test type float level switch can be conveniently at any time to switch and self detection system, to ensure the safe operation of the system and the switch.

Four, main features:

1, advanced design and strict manufacturing process provides a reliable guarantee for product quality.

2, ABS, PP, the shell is made of PVC plastic, high strength, good corrosion resistance.

3, cable with special materials, oil resistant, acid, alkali, corrosion resistance is superior.

4, simple structure, reliable performance. Stable and reliable output on and off switch signal, no misoperation, high reliability.

5, simple installation, convenient debugging, on the positioning block, can freely adjust the liquid level control range.

Five, technical parameters:

1, rated current: 16A-120VAC; 10A-300VAC; 0.6A-150VDC;

2, an independent contact output: SPDT contact;

3, contact material: silver (Ag);

4, body material: precision alumina ceramics;

5: die casting magnesium alloy shell, switch surface polishing of polyurethane coating;

6, the rated temperature: Standard Type: -40~250 ~ C;

7, high temperature type: 370 ~ C;

8, pressure rating: ANSI Class150 and 300, 600, 900LB, PN1.0;

9, process connection: flange connection, 80 DN50, 100 2'~4 ANSI; ";

10, medium density: 0.40g/cm3;

11, electrical interface: M20 * 1.5, 1/2'NPT female;

12, flameproof explosion-proof grade: Exd II BT4 II CT6 Exia intrinsically safe;

13, protection grade: IP65.

Six, installation instructions:

External installation:

1, the installation location should be away from the water inlet, otherwise the switch will malfunction caused by the fluctuation of water inlet.

2, if the float level switch device in the vessel wall, can be installed L type steel bracket.

3, if the switching device can be installed in the stirring area, wave tube or wave baffle.

4, the selection of pipe flange diameter greater than the diameter of the connecting pipe of the floating ball.

Recommend the use of multiple core cable wiring, 5.

6, controlled by the line load must match the float switch contact capacity.

7, the measured liquid proportion must be greater than the proportion of floating ball.

8, the floating ball movement has orders in the factory is adjusted according to the customer, please do not arbitrarily adjust the float position.

Internal wiring installation:

1, when the float switch used in motor, relay, solenoid coil circuit has an inductive load, in parallel across the load protection circuit such as: RC (buffer), rheostat, diode etc..

Note: please do not float switches are directly connected to the electromagnetic valve, motor or solenoid switch.

2, when the floating ball switch is used in capacitors, hot bulb, long cable and capacitive load, will produce a surge current in the switch contacts; in the float switch is connected in parallel with the protection circuit, such as current limiting resistors or surge absorber etc..

Seven, wiring and contact instructions:

1, open the box, the cable from the inlet through, and lock line inlet cable fixed head, according to the nameplate and wiring board terminal station logo on the terminal of the contact line on the corresponding access.

From the 2 wiring board, digital identification terminal table corresponding to a contact from top to bottom of the floating ball.

3, float ball joint is divided into three forms:

1A said: when the liquid level is higher than the floating ball contact A-C;

The 1B said: when the level is below the floating ball contact B-C;

The 1AB said: when the A-C level is below the floating ball contact open, B-C connected; the liquid level is higher than the floating ball when the A-C contact is connected, disconnect the B-C.

4, please tighten the lid after the completion of the connection and the connecting port is fixed, in order to ensure the waterproof junction box.

Eight, matters needing attention:

1, regular cleaning of debris and dirt rod and the floating ball (depending on the water quality and cycle);

2, regular inspection of all parts are firmly;

3, should consider the proportion of liquid, in order to ensure the smooth float to float;

4, the control circuit load does not overload use (less than the capacity of contact use);

5, electrical wiring box interface must be down;

Please choose anti-corrosion type 6, alkali liquid;

7, the floating ball and the connecting rod is connected with the container tube shall not touch the process.

Nine, common faults and exclusion:

1, failure analysis and troubleshooting of floating ball movement

The liquid proportion is less than the proportion of floating ball to re confirm the proportion of floating ball;

The floating ball, and the Water Leakage company to replace the floating ball;

The floating ball to remove foreign bodies stuck in foreign body.

2, the floating ball moves, but no signal output

The float position offset, adjust the float position;

The magnetic reed switch is damaged, replace the magnetic reed switch.

3, the output signal is not normal, to eliminate the magnetic field near the magnetic field interference;

4, maintain the signal, unable to recover, the floating ball can not return, a foreign body stuck to remove foreign bodies;

5, there will be a two signal output, ring position, adjusting ring buckle position.
