1, before commissioning must ensure that the pump and pipeline full of water, so as not to damage the pump.
2, the pump is filled with water to open the pump bleeder valve for exhaust, so as not to cause unstable pipeline pressure can not be normal pressure regulation.
3, the cabinet door on the surface of the manual stop automatic transfer switch, hit the manual for the frequency start, automatic inverter start by the outlet pipe remote pressure gauge according to the set pressure automatic control.
4, due to manual and automatic power supply into the line is not the same, so the manual and automatic pumps are not the same, all pumps to work manually are adjusted to the positive, automatic reversal of the frequency converter output on the U2, V2, W2, any two-phase switching can be.
5, set the pressure to stop the pump (i.e., the maximum pressure) just press (ENTER) on the inverter panel into the display (REF) and then press (ENTER) into the display of 40% (i.e., 0.4MPa pressure), such as the need to increase and decrease the pressure according to the (Increase key) or (Decrease key) to set the required pressure value (i.e., the pressure stop the pump), set the value of the pressure and then press (ENTER) to save, then the After setting the pressure value, press (ENTER) to save it, and then press (EXIT) to return to the main interface to complete the setting; the pump pressure is based on the highest pressure to be converted by itself without setting.

Submersible sewage pumps are submersible sewage pumps that are particularly suitable for transferring liquids containing hard solids, fibrous materials, and particularly dirty, sticky and slippery liquids. There are two types: AS and AV submersible sewage pumps.

QW submersible sewage pump is a kind of pressure pump with large flow channel anti-clogging hydraulic parts design, which greatly improves the dirt passing ability.

Pipeline centrifugal pumps are general-purpose equipment for conveying clear water and liquids with similar physical and chemical properties, widely used in industrial and urban water supply and drainage, high-rise building pressure boosting, fire-fighting systems, HVAC circulation and other fields [2]. According to the installation form can be divided into vertical and horizontal, according to the impeller structure is divided into closed, open and semi-open [1], the adaptable medium temperature range -20 â?? to 240 â?? [3], typical models include ISG, ISW, IRG, etc. [2] [4].
The equipment consists of impeller, pump body, sealing ring and other core components, the impeller rotates to generate centrifugal force to achieve liquid transport, the pump body plays a supporting role, and the sealing system to protect the operating vacuum. It adopts modular piping design, equipped with high-efficiency hydraulic model, supports electric drive and direct connection structure, featuring low noise, small footprint and easy maintenance. Installation requires precise calculation of suction height and ensuring pipeline sealing, and the performance curve reflects the relationship between flow rate, head and power [4]. Common faults such as air binding can be solved by filling water and exhausting air, and the bearings and sealing parts need to be overhauled regularly [2].
