ZW-UQK series Ordinary type float level controller Is the use of direct drive float switch inside the magnet, it is simple to make the switch instant action lever. A cantilever angle spacing design to prevent vertical float. The float switch is a liquid level controller has the advantages of simple structure, convenient use, safe and reliable. It is larger than the general mechanical switching speed, long service life; compared with the electronic switch, it has the characteristics of anti impact load ability, realize multipoint control of a product can be.

Two, work principle:

ZW-UQK series of <strong> ordinary type float level controller</strong> is composed of isolated float group and contact group is composed of two parts. When the liquid level is increased or decreased, the floating ball 1 come down the end of the magnet 2 swing up and down, through magnetic force, repulsion mounted in the housing 3 in the same pole magnet 4 swing up and down, the other end of the movable contact 5 is 1-1 and 2-2 in the static contact or connectivity disconnect. The liquid has buoyancy, and the float system (generally have the corresponding auxiliary equipment) is based on the liquid buoyancy and supporting the production, when the liquid level rises, float system is rising, so when the liquid level drops also decreased, when the rise or fall to the set position, floating the ball is in the system will meet the travel switch set position (or other microelectronic devices), so that the switch sends electrical signals, and the electronic control device will immediately after receiving the action signal, cut off or connected to the power supply, automatic control system formation.

Three, application:

ZW-UQK series of <strong> ordinary type float level controller</strong> is suitable for all kinds of industrial equipment, household appliances and other oil and water machine. Stainless steel float switch for liquid level detection, all kinds of small and medium pressure and pressure of liquid storage tank remote signal, alarm switch, can be applied to a variety of health, environmental protection, poisonous and corrosive medium with strong acid liquid. Home appliance or mechanical and PP plastic floating ball is mainly used in hot water, such as water heaters, water machine, dishwasher, electric water heater, hydraulic machine, air compressor, and other ancillary equipment.

Four, main features:

1. can be installed on the level of the tank wall, also can be installed on the vertical tank top;

2. has the advantages of simple structure, reliable performance, convenient installation;

3. control part and the measured liquid medium is completely isolated, with the use of high temperature and high pressure environment;

More than 4. material, connection mode can meet the needs of different environment;

5. a wide range of applications: food, medicine, chemical, electronics, shipbuilding, water treatment and other industries,

Six, the nature of the liquid medium and float relationship:

1, the liquid proportion does not change at the same time, action position will float, generally higher than water hours, the floating ball dipped in the liquid part will be relatively increased.

2, the proportion of float switch product reference with water (SG=1) so when used in the selection of the floating ball must be considered when the liquid level is greater than the proportion of floating ball size indicated, otherwise, the float switch can not float.

3, high viscosity liquid will not dry, should generally be used for large diameter floating ball.

4, the float switch is used to sense the magnetic reed switch, the liquid level should therefore be free of iron, otherwise it will affect the correct action team floating switch.

Seven, selection description:

Please use the measured object in accordance with the characteristics of temperature, pressure, density, acid and alkali, the list of various specifications of the floating ball.

1, PVDFzui high temperature: the temperature of 120 DEG PPzui, 80 C, 200 c SUS304/316zui.

2, pressure: plastic floating ball pressure Zui 5kg/cm2, SUS Zui 30kg/cm2 high pressure float.

3, adhesion: floating ball ball, should be used to overcome the small proportion of liquid surface tension.

4, of plastic material is suitable for the places such as temperature pH, consideration should be used in PVDF.

5, oil: the use of metal materials.

6, the proportion of floating ball: the proportion of SG must be less than the measured liquid, or float float.

7, voltage: 220VAC current: 0.7A.

Eight, installation method:

1, the installation should be far away from the inlet (outlet) nozzle, so as to avoid water fluctuations caused by misoperation;

2, installed in the mixing area, can be installed at the tube or baffle;

3, junction box line inlet to down;

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

5, the floating ball and the connecting rod to move up and down the angle (horizontal line) to + 14 degrees, when the floating ball in the horizontal position switch;

6, the installation should pay attention to and the connecting pipe length and aperture size matching, to ensure that the floating range of the floating ball.

Note: the total length of the floating ball and a connecting rod part to allow a certain degree of error.

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, control circuit of the load can not use overloading (less contact capacity);

5, electrical wiring box interface must be down;

Please choose anti-corrosion liquid, pH 6;

7, the floating ball and the connecting rod and the connecting tube against the container shall not process.

Ten, specification data sheet:

Eleven, The selection of encoding:

Note: Please specify the specific process of connection, the size and position of action point.

Twelve, design selection and ordering information:

1, the liquid level switch device specifications;

2, measuring range;

3, working pressure and temperature;

4, material control device;

5, the special requirements of negotiation;
