FAQ
D-type multi-stage pump is a simple series connection of many single-stage pumps, combined together. His output water pressure can be very high. It is a type of centrifugal pump that relies on the rotation of the impeller to obtain centrifugal force and produce materials. When the gas density reaches the working range of the mechanical vacuum pump and is extracted, gradually obtaining high vacuum. The D-type multi-stage pump relies on changes in pump chamber volume to achieve suction, compression, and exhaust, making it a variable volume centrifugal pump.
The maintenance of a D-type multi-stage pump is relatively complex, but as long as a daily management mechanism is established, regular inspections are carried out, and maintenance of the D-type multi-stage pump is not difficult. Below are a few common issues that need to be briefly introduced.
(1) Insufficient traffic?
Reason for occurrence: Insufficient flow is mainly caused by leakage of suction pipes and bottom valves; Water inlet blockage; Insufficient water inlet depth of the bottom valve; The speed of the water pump is too low; Excessive wear of the sealing ring or impeller; Excessive water absorption height, etc.
Solution: Check the suction pipe and bottom valve, block the gas leakage source; Clean up the silt or blockages at the inlet; The inlet depth of the bottom valve must be greater than 1.5 times the diameter of the inlet pipe, and the inlet depth of the bottom valve should be increased; Check the power supply voltage,
Increase the speed of the water pump and replace the sealing ring or impeller; Lower the installation position of the water pump or replace the high head water pump.
(2) Excessive power consumption?
Cause: High rotational speed; The spindle is bent or the pump spindle is not concentric or parallel to the motor spindle; Inappropriate pump head selection; Pump suction of sediment or blockage; Damage to motor ball bearings, etc.
Solution: Check the circuit voltage and reduce the speed; Correct the main shaft of the pump or adjust the relative position between the water pump and the motor; Select a pump with appropriate head; Clean up sediment or blockages; Replace the ball bearings of the motor.
(3) Does the pump body vibrate violently or produce noise?
Cause: Improper installation or excessive installation; Motor ball bearings are damaged; The spindle is bent or not concentric or parallel with the motor spindle.
Solution: Install the water pump steadily or lower the installation height of the pump; Replace the motor ball bearings; Correct the bent spindle or adjust the relative position of the pump and motor.
(4) Is the transmission shaft or motor bearing overheating?
Causes: Lack of lubricating oil or bearing rupture, etc.
Solution: Add lubricating oil or replace bearings.
(5) Not coming out of the water?
Cause: The pump body and suction pipe are not fully filled with water; The dynamic water level is lower than the water pump filter pipe; Broken suction pipe, etc.
Solution: Eliminate the malfunction of the bottom valve and fill the water intake with water; Lower the installation position of the water pump to keep the filter pipe below the dynamic water level, or wait for the dynamic water level to rise before pumping water from the filter pipe; Repair or replace the suction pipe.

Product Introduction
Product Overview
This series of pumps is a horizontal single suction multi-stage segmented centrifugal pump, which adopts the hydraulic model of high-efficiency energy-saving products recommended by the country. It has the advantages of high efficiency, wide performance range, safe and stable operation, low noise, long service life, and easy installation and maintenance, and occupies a leading position in the industry.
Horizontal multi-stage centrifugal pumps are mainly divided into the following types according to their usage scope:
D-type: D-type pumps are used to transport clean water or liquids with physical and chemical properties similar to clean water that do not contain solid particles and have a temperature below 100 ºC. Suitable for use in mines, factories, and urban water supply and drainage engineering.
MD type: suitable for mining enterprise users to transport liquids containing certain impurities such as coal powder particles and small amounts of impurities in mine water, with liquid temperature below 100 ºC.
DF type: The DF type pump is used to transport corrosive liquids that do not contain solid particles and have a temperature range of -20 ºC~105 ºC. The allowable inlet pressure of the pump is less than 0.6MPa.
DG type: suitable for feed water of medium and low pressure boilers or sub high pressure boilers, as well as urban high-pressure water supply and drainage. The conveying medium temperature is -20 ºC~180 ºC, and the inlet pressure is less than 0.6MPa.
