7 Suction Control via Constant Pressure w/Well Draw Down

 Overview

This function enables the iQpump Controller to monitor suction pressure at the inlet of the pumps.

Note: This function is active when parameter P8-01 is set to 2 for Suction Control.

Packaged Booster Systems have a desired discharge pressure and a given suction pressure from the city water system or from a suction tank. Such systems are often designed to handle a specific pressure and flow rate.

The suction pressure may have a wide range between high and low pressures. The suction pressure typically decreases with increased fluid flow rate. In some instances, pump cavitation may occur if suction pressure falls below a certain pressure level.

In addition low or negative suction pressure can lead to damage such as pipe collapse due to external forces acting on the pipe.

The iQpump Controller will accept an analog suction transducer (Terminal A1) and can be programmed to trigger an alarm or shutdown the system when the suction pressure falls outside of a normal operating range.The iQpump Controller will automatically restart and return to normal operation once the suction pressure returns to a normal level.

When operating in multiplex mode, additional control can be programmed to de-stage any active pumps as a method to try and reduce pump loading to prevent suction pressure from continuing to drop below the shut down level.

 Function Description

The iQpump Controller will regulate outlet pressure of the pump system using the standard iQpump Controller features when there is adequate suction pressure available at the inlet of the pumps and offers two options to respond to a drop in suction pressure.

1. Regulate Outlet Pressure and Suction Pressure: (P8-03 > or = P8-04) To regulate suction pressure set the suction pressure setpoint (P8-03) to a value greater or equal than the minimum suction pressure (P8-04). In this mode the iQpump Controller will try to regulate the suction pressure based on the programmed suction pressure setpoint (P8-03) level.

As the suction pressure decreases and approaches the suction pressure setpoint level (P8-03), the iQpump Controller will slow down causing the outlet pressure and flow to decrease. When the suction pressure rises above the P8-05 level for more than the P1-05 time, normal operation (outlet pressure regulation) will resume.

When the suction pressure drops below Minimum Suction Pressure (P8-04), for more than the Sleep Delay Time (P2-03), the iQpump Controller will go to sleep.

Note: The Suction Control Minimum Speed parameter (P8-06) should be set to a high enough value that will ensure flow.

2. Regulate Outlet Pressure Only: (P8-03 < P8-04) Set the suction pressure setpoint (P8-03) to a value smaller than the minimum suction pressure (P8-04) to regulate outlet pressure.

This mode allows the iQpump Controller to maintain the outlet pressure setpoint using the standard iQpump Controller features and go to sleep immediately when the suction pressure drops below the Minimum Suction Pressure (P8-04), for more than the Sleep Delay Time (P2-03).

Normal operation (outlet pressure regulation) will resume when the suction pressure returns above the P8-05 level for more than the P1-05 time.

7 Suction Control via Constant Pressure w/Well Draw Down

 Duplex System Example

A pump system consisting of a duplex domestic pressure booster system using a pressured city supply averaging 40

Example:

Pump System Settings

• All pumps have the same flow rate and will alternate

• Lag Pump will track speed of lead pump

• All drives have individual discharge transducers rated 150 psi. Upon failure, system will look to network for feedback information.

• Suction Transducer is rated 75 psi

• Below 40 psi city pressure the pump system will start to reduce speed until reaching 30 psi

• System Auto setpoint 85 psi, with a 5 psi start level.

Duplex System Example (Related Parameters)

- 60 psi. If city pressure starts to fall below 40 psi the pump system will start to slow down to reduce the chances of pump cavitation. When suction pressure (city pressure) drops to 30 psi, the pump system will shut down (sleep) and wait until city pressure returns, after which the system will automatically start and operate under normal condition.

This drive will transmit its Water Level/Suction Pressure signal to the network. If this signal is lost, the drive will not switch to another signal on the network. The detection action in this mode is solely on parameter b5-12.

P9-50 = 1 (Ana->Net, No Alarm)

This drive will transmit its Water Level/Suction Pressure signal to the network when the analog input is healthy. If this signal is lost, the drive will switch to another signal on the network if available. If there are no available network signals, then this drive will act according to the setting of parameter b5-12 (when = 1 or 2).

Note: Setting parameter b5-12 to 0 will disable analog feedback detection and will prevent the iQpump Controller from switching to the

Network Water Level/Suction Pressure.

P9-50 = 2 (Ana->Net, Alarm)

This drive will transmit its Water Level / Suction Pressure signal to the network when the analog input is healthy. If this signal is lost, the drive will switch to another signal on the network if available. An alarm will be displayed indicating that the analog signal has been lost and that the signal is coming from the network. If there are no available network signals, then this drive will act according to the setting of parameter b5-12 (when = 1 or 2).

Note: Setting parameter b5-12 to 0 will disable analog feedback detection and will prevent the iQpump Controller from switching to the
