KP: Odlično funkcionisanje i laka montaža

Presostati serije KP su konstruisani da zaštite rashladne instalacije od previsokih pritisaka na potisu, pren-

iskih pritisaka na usisu, da pokreću/zaustavljaju kompresore ili da upravljaju ventilatorima na vazduhom

hlađenim kondenzatorima. KP termostati sa adsorpcionim punjenjem su optimalan izbor za zaštitu od

smrzavanja čilera. Pojačani sistem kontakata za 16 A omogućava da rade sa elektromotorima do 2 kW

direktno, bez upotrebe kontaktora.

KP features The contact system in KP pressure switches has a snap function. This means that the bellows is active only when the cut-in or cut-out value is reached.The bellows is connected to the pressure of the controlled plant via the connector (7).

The design of KP pressure switches gives the following advantages:

• High contact load• Ultra-short bounce times• Vibration-proof in the range 0-1000 Hz, 4 g (1 g = 9.81 m/s2)• Long operating life• High pulsation protection• Small dimensions – Easy to mount in panels

KPI features Danfoss KPI pressure switches are designedso that the bellows moves in the sameproportion as the pressure change.To ensure a snap function on contact change-over, an omega spring is located between bellows and contact system.

The design of KPI pressure switches gives the following advantages:

• High contact load• Ultra-short bounce times• Vibration-proof in the range 0-1000 Hz, 4 g (1 g = 9.81 m/s2)• Long operating life• Can be used for both liquids and gases• Small dimensions – Easy to mount in panels

The lefthand pressure bellows switches the pump pressure. The righthand bellows cuts out the pump if the pump suction pressure is too low. In this way the pump is protected from running dry and consequent bearing damage.

Danfoss dual pressure switch KP 44 is designed for use as a pump guard to control and protect supply water pumps. The KP 44 pump guard combines the function of a pressure switch and a fl ow monitoring device.

The switch in the KP has a snap-action function, and the bellows moves only when the cut-in or cut-out value is reached.

Water supply from reservoir or well If water is running short in the well or reservoir, the pump will no longer be able to increase the pressure to the cut-out value. Consequently the pump will keep running - perhaps without water. However, the KP 44 pump guard will stop the pump as soon as the righthand bellows pressure drops below the safety cut-out setting.

The pump can be started again by lifting the impulse lever. The pump will continue to operate when the impulse lever is released, provided that the righthand bellows pressure is higher than the safety cut-out setting plus a fi xed diff erential of 1 bar. If this is not the case, the pump will cut-out again indicating insuffi cient water supply.

Pressurized water supply direct to pumpWhen water supply fails on the inlet side, the pump will no longer be able to boost the pressure to the cut-out value. Consequently the pump will keep running - perhaps without water. However, the KP 44 pump guard will stop the pump as soon as the pressure in the pump suction line drops below the safety cut-out setting. The pump will automatically start again when the pump suction pressure has reached the level of 1 bar above the safety cut-out setting.

Automatic start-up will only take place if the righthand bellows is connected to the pump suction line. Air pockets should be avoided to prevent the pump from starting up on air pressure rise, without the presence of water.

In a hydrophore system where water is pumped from a well or an open tank, both bellows are connected to a pressure outlet on the air side in the pump pressure line, if possible.

In a booster system receiving pressurized water the righthand bellows is connected- to the low pressure side of the pump for automatic start-up.- to the high pressure side of the pump for manual start-up.The lefthand bellows is always connected to the high pressure side of the pump.

10 IC.PD.P10.F1.02 - 520B2008


Pressure settings Safety cut-out settingThe righthand bellows will automatically cut-out the pump at the safety cut-out setpoint. Automatic start-up, if any, will take place when the pressure has reached the level of 1 bar above the setpoint. Manual cut-in is made by lifting the impulse lever and releasing it again when the pressure has increased by min. 1 bar.

The safety cut-out setpoint is normally determined by the static pressure (the water column). However, in order to avoid disturbing signal interaction, care should be taken to ensure that the safety cut-out setting is at least 1.5 bar lower than the control pressure cut-in setting. See table with pressure setting examples below.

Required tap water pressure ≥2.3 bar ≥4.0 bar ≥5.0 bar ≥8.0 bar

Control pressure cut-out setting 3.0 bar 5.0 bar 8.0 bar 12 bar

Diff erential 0.7 bar 1.0 bar 3.0 bar 4.0 bar

Control pressure cut-in setting 2.3 bar 4.0 bar 5.0 bar 8.0 bar

Max. safety cut-out setting 0.8 bar 2.5 bar 3.5 bar 6.0* bar

* 6.0 bar is the normal max. setpoint

Control pressure settingsControl pressure cut-out setpoint is set on the lefthand pressure setting scale.

The diff erential is set between 0.7 and 4 bar.The control pressure cut-in setting will be the cut-out control pressure less the diff erential.

Danfoss KP thermostats are used for regulating, monitoring and alarm systems in industry.KP thermostats are temperature-operated electric circuit breakers. The thermostats are fi tted with a single-pole switch (SPDT)

The position of the switch depends on the thermostat setting and sensor temperature. A KP thermostat can be connected and switch to single-phase alternating current motors of up to about 2 kW.

Description

Diff erentialThe diff erence between cut-in and cut-out temperature. The diff erential is a condition for stable automatic plant operation.

Mechanical diff erential (intrinsic diff erential)The diff erential set on the diff erential spindle of the unit.

Working diff erential (thermal diff erential)The diff erential on which the plant operates. The working diff erential is the sum of the mechanical diff erential and the diff erential arising from the time constant.

Reset1. Manual reset. Resets only when the reset button is pressed. Min. reset units will restart after the temperature at the thermostat sensor has risen by a value greater than that of the fi xed diff erential. Max. reset units will restart after the temperature at the thermostat sensor has fallen by a value greater than that of the fi xed diff erential

2. Automatic reset. Units with automatic reset restart automatically after stop.

Drawing showing principle of KP thermostats

KP 75 room sensor

The contact system in KP thermostats has a snap function. This means that the bellows is active only when the cut-in or cut-out value is reached.

The design of KP thermostats gives the following advantages:

• High contact load • Ultra-short bounce times. Limits wear to an absolute minimum and increases reliability.• Vibration-proof in the range 0-1000 Hz, 4 g (1 g = 9.81 m/s2)• Long operating life

Setting Thermostats with automatic resetSet the upper limit temperature on the range scale. Then set the diff erential on the DIFF scale.The temperature set on the range scale is also the temperature at which contact changeover re-occurs on rising temperature.The contacts changeover when the temperature has fallen to a value lower than that set on the DIFF scale.If at lower settings the plant will not start/stop, the reason might be that the diff erential has been set too high.

Thermostats with minimum resetSet the temperature on the range scale. The diff erential setting is fi xed. Min. reset units will restart after the temperature at the thermostat sensor has risen by a value greater than that of the fi xed diff erential.

Thermostats with maximum resetSet the stop temperature on the range scale. The diff erential setting is fi xed. Max. reset units will restart after the temperature at the thermostat sensor has fallen by a value greater than that of the fi xed diff erential

Charges Absorption chargeThe charge consists partly of a superheated gas and partly of a solid substance with a large absorption surface.The solid substance is concentrated in the sensor (17), and consequently it is always the sensor that comprises the temperature-regulating part of the thermostatic element.The sensor can be placed both warmer or colder than the thermostat housing and capillary tube. However, placing it in an ambient temperature higher or lower than +20 °C can aff ect the accuracy of the scale.
