产品介绍

The XBD-ALG series vertical single-stage single suction fire pump is used to transport clean water without solid particles and liquids with physical and chemical properties similar to water. Mainly used for boosting water supply in fire protection systems, and can also be used for water supply and drainage in factories and mines. The flow rate range for conveying liquids is 5-100L/S, the pressure range is 0.3-160Mpa, the matching power range is 7.5-250KW, and the caliber range is Φ 50-Φ 250mm.

The ALK series electrical control cabinet has a wide range of applications. For various occasions, such as domestic water supply, fire sprinkler pressurization, air conditioning cooling circulation, industrial control pumps, sewage discharge, etc., there are corresponding model specifications. Control motor power range: 0.75~355KW.

ALK series electrical control cabinets have excellent quality. Carefully selected electrical components and high-quality standard cabinets, meticulously designed and crafted.

The ALK series electrical control cabinet is fully functional. From one control one to one control four, the main and backup pumps can be freely selected and combined, with multiple starting methods, various control types, fault prevention and switching, and can also be specially designed for you.

Water pumps with a general motor power of 15KW or less are started directly. Z: Sewage pumps above 15KW are generally started using self coupling pressure reduction, and fire and sprinkler pumps can also be started using this method, which is suitable for situations where starting is not frequent. Y: If there are no special requirements for other models of water pumps above 15KW, they are generally started using the Y - △ pressure reduction starting method.

The soft start control device utilizes advanced microprocessing to control high-power thyristor components, achieving functions such as software start, soft stop, and power saving for AC induction motors. Soft start refers to the process in which the output voltage of a device increases in a regular manner, causing the controlled motor voltage to rise from zero to full voltage, and the corresponding speed smoothly accelerates from zero to the rated speed.

Energy saving operation refers to the automatic adjustment of the output voltage of the device based on the load situation to improve the power factor of the motor during light load operation, in order to achieve the goal of energy saving. Soft start can make the starting and stopping torque curves of the water pump approach the pump torque characteristic curve, greatly eliminating the electrical and mechanical starting impact of the pump and system, making the starting extremely reliable.

【 Performance and characteristics of soft start 】 1. Slope voltage starting and constant current soft start can be selected to limit the voltage drop during starting and reduce the peak current. Limit the starting torque to protect the transmission machinery. Smooth acceleration, deceleration, or braking to protect equipment and personnel. Mechanical protection for transmission machinery can eliminate torque surges and reduce surge currents. 2. The starting parameters can be easily adjusted to adjust the starting current, voltage, and time according to different loads, achieving small current surges. 3. Extending the lifespan of motors and water pumps, soft start provides a smooth and gradual starting process for motors, reducing equipment vibration and noise. Eliminating the surge current during startup. Reduce motor losses. 4. When the high-efficiency energy-saving motor is under light load, the soft starter can reduce the terminal voltage, improve the motor power factor, and achieve energy-saving under light load. 5. The soft parking function can prevent the water pump from experiencing the 'water hammer' effect. 6. Simple to operate, stable to run, and reliable, the automated control can be put into safe and continuous operation without maintenance once the system is debugged and running normally. 7. The comprehensive protection function has multiple protections such as overcurrent, overvoltage, overload, phase loss, short circuit, overheating, etc. 8. It can be connected to a computer through a serial port to achieve direct monitoring of computer networking.

The switching mode between the main and backup pumps for multi pump control is not specified as a regular type. Before starting up, the main pump and backup pump are manually selected using a switch. After the main pump fails, the backup pump automatically switches on. This method is generally used for controlling the main and backup pumps. AS: Timing automatic switching/manual switching is suitable for situations where the main and backup pumps need to be used alternately at regular intervals, so that the long-term continuous working time is evenly distributed between the main and backup pumps. The regular switching time is 8-12 hours, which is a selective type. When there is no need for timed automatic switching, the switch can be switched to manual switching mode to select the main and backup pumps. This model has a backup pump self switching function. AC: Alternating automatic switching/manual switching: The ALK series electrical control cabinet requires alternating working environments for the main and backup pumps. Every time it is started, the main and backup pumps are exchanged. When there is no need to alternate, the switch can also be switched to manual mode to select the main and backup pumps. This model has a backup pump self switching function. ALK series electrical control cabinet type description: not specified as manual control, the water pump start stop is controlled according to the control cabinet door panel start stop button. L-type: liquid control. Equipped with a float switch, it can reliably achieve changes in liquid level and automatically control the start and stop of the water supply and drainage pump. The LQ type S adds full protection function on the basis of the L type, and according to the characteristics of submersible pumps, in addition to main circuit short circuit, short phase, and overload protection, it also has pump body leakage protection, motor overheating protection, and leakage protection functions. P-type: Pressure controlled type. By using an external electric pressure gauge or pressure controller, it is possible to automatically turn on and off the pump in response to changes in network pressure. Large scale application in domestic water supply and fire pressure boosting systems. As this box is also suitable for controlling water pumps with Key float switches and remote control with limit switch buttons, it is a 'universal interface' motor control box with a wide range of applications. S-type: Time controlled type. This control box does not have a time setting button or display, and users can control the opening and closing of the water pump according to their timing needs. Suitable for controlling various timed and regular intermittent working modes. X-type: Fire specific type. This model is designed according to the National Fire Protection Center, and the start of the fire sprinkler pump can be manually operated by ① the chassis panel; ② Each fire hydrant button or pressure switch is activated; ③ The DG24V of the fire control center is activated, and there is a passive signal contact for the pump stop and start output of the fire control center as feedback. XF type: fire CCCF special type, designed according to the new standards of the National Fire Protection Center. The start of the fire sprinkler pump can be manually operated by the ① box panel; ② Each fire hydrant button or pressure switch is activated or the flow switch is activated; ③ The DG24V of the fire control center is activated, and there is a passive signal contact for the pump stop and start output of the fire control center as feedback.
