QZ Series Submersible Axial Flow

Product Introduction
Submersible pump stations have rapidly developed due to their simple construction, low engineering cost, convenient maintenance and management, easy operation and automation, good work reliability, and environmental beautification.
The main equipment of a submersible pump station is the submersible electric pump (referred to as submersible pump), which includes the QZB submersible axial flow pump and QH (B) submersible mixed flow pump. It is an electromechanical product that combines the motor with the axial flow pump and mixed flow pump, and is an updated version of the traditional long axis axial flow pump and mixed flow pump.

Product Description

Submersible pumps and traditional long shaft pumps have significant advantages in terms of usage scenarios, inlet and outlet conditions, and characteristic parameters, as well as the following:
Save over 30% of the total investment in pump station engineering:
★ Save over 40% in construction period:
★ Unit installation time saved by over 95%;
Reduce the weight of the unit by more than 50%:
★ Save investment in flood control walls for pump stations:
★ Low maintenance costs:
★ No operating noise, easy to operate, and easy to automate:
The low height of ground buildings can eliminate the need for pump room construction, and even allow for the construction of pump stations below ground level.
Therefore, new and old customers of axial flow pumps and mixed flow pumps can easily replace submersible pumps in new pump station projects, and can be updated with submersible pumps in old pump station renovation projects. This type of pump is mainly suitable for the following situations:
★ Irrigation and Drainage of Farmland:
★ Municipal discharge of rainwater and mild sewage:
★ Process water and cooling water in industry:
★ Water conservancy middle note project.

Our company's submersible pumps come in ten nominal outlet diameters, including 350, 500, 600, 700, 800, 900, 1000, 1200, 1400, and 1600. The flow range is 0.12-12m3/s, the head range is 2-14m, the power range is 7.5-630kW, and the voltage levels are 380V, 660V, 3kV, 6kV, and 10kV.

Model Description

1. Submersible axial flow pump

2. Submersible mixed flow pump


Structural Description

The QZB submersible axial flow pump and QH (B) submersible mixed flow pump are composed of four major parts: the inlet horn mouth, impeller components, impeller housing, and guide vane body. The submersible motor is a fully sealed dry-type asynchronous motor. The motor is enclosed by a casing, and there is a static sealing device at the cable outlet on the upper end of the motor. There is a rotating sealing device at the shaft cover on the lower end of the motor. The submersible motor has all the safety and reliability performance for submersible operation. There are monitoring, alarm and protection devices for sealing leakage, coil and bearing temperature rise, which do not affect the early leakage of the motor's normal operation (only alarm). When the coil temperature exceeds 135 ℃ and the bearing temperature exceeds 90C, power-off protection is used, and all protectors are monitored by a dedicated submersible pump protector to ensure the safe use of the submersible pump.

Installation form and size

The smaller QZB series submersible axial flow pump and QHB series submersible mixed flow pump adopt open inlet, and the installation forms include wellbore bend installation, steel wellbore installation, and concrete prefabricated wellbore installation. The installation of bent pipes and steel shafts is provided by our company as a complete set of shafts. The installation of precast concrete shafts is provided by our company with installation bases (including anti rotation devices) and covers. During installation, lift the submersible pump into the wellbore until it reaches the bottom. The inclined surface on the guide vane body matches the inclined surface of the support, and the water stop rubber (O-ring) plays a sealing role. Larger submersible pumps (with impeller diameters generally above 1 meter) are installed in a form with a closed inlet channel.

Note:
(1) The dimensions in the table refer to the installation dimensions of the pump and the hydraulic control dimensions designed for the pump station. The hydraulic dimensions designed for the pump station are only for reference.
(2) Dimension A is determined based on the flow rate to control the flow rate and reduce hydraulic losses. The dimensions in the table are reference values and can be appropriately increased if necessary. Dimensions E and J are determined based on the specific conditions of the pump station. Dimension R is the minimum reference size and can be appropriately increased if conditions permit. The above dimensions are determined according to user requirements.
(3) The distance between the pump center and the rear pool wall is ≤ K.
(4) The center distance between two pumps in the same pool is ≥ L.

1、 Open type inlet (inlet pool)

Open type inlet (water tank) has a simple structure and easy construction, and is widely used in small and medium-sized pump stations. The hydraulic design of this type of channel is highly valued both domestically and internationally, and extensive experimental research has been conducted. Many researchers have proposed design criteria for open inlet tanks in the form of empirical coefficients based on experimental results. However, there are significant differences in the criteria proposed by various parties, and there is still no unified or optimal hydraulic design criterion. Below are general design reference criteria.

The hydraulic design of an open inlet (inlet pool) is generally based on the inlet diameter D of the horn pipe. The main reason for this is that the water flow into the pump first passes through the cylindrical surface between the horn pipe mouth and the flow channel bottom plate, and then enters the pump through the horn pipe mouth. It is natural to determine the size of the inlet channel based on the diameter of the horn tube as the basic parameter. But the problem is that the current design of the horn tube has not been standardized, and the inlet diameter of the horn tube is a variable. The ratio of the inlet diameter of the horn tube to the diameter of the pump impeller may not be the same. If D. is used as the basic parameter, it will cause confusion in hydraulic design criteria and appear inappropriate. If the horn tube can be standardized, the hydraulic design of the inlet channel should be based on the horn diameter or impeller diameter as the basic parameters. Otherwise, the pump impeller diameter should be used as the basic parameter.

According to the data "Optimization of Hydraulic Design for Pump Station Inlet Channel", the recommended design for open inlet is as follows

(1) Suspended height M

The recommended suspended height is M=(0.68~1.2) D. For larger or smaller horn tube inlet diameters (1.67D.), take the smaller value, and for smaller horn tube inlet diameters (1.46D.), take the larger value: For larger or smaller horn tube inlet diameters, the value of suspended height can still be within this range.

(2) Rear wall distance T

The determination of the distance between the rear walls is basically not affected by the use of a horn tube for water suction. Some water flow must enter the pump from the rear of the horn tube, so a certain distance between the rear walls is necessary; However, the excessively large distance between the rear walls increases the degree of freedom of water flow in the rear wall space, increases the possibility of vortex generation, and requires a corresponding increase in submergence depth. According to the optimization calculation results, the rear wall distance is taken as (0.8-1.0) D. It is sufficient to meet the requirements.


(3) Pool width Bj

In order to allow a portion of the water flow to smoothly enter the pump from both sides and behind the horn pipe, a certain pool width is required: excessively large pool widths can suddenly increase civil engineering investment. The diameter of the horn tube inlet to some extent affects the determination of the optimal pool width. Based on the optimization calculation results, it is recommended that the pool width be (3.5-4.5) D. The inlet diameter of the larger horn tube is taken as the smaller value, and the inlet diameter of the lighter horn tube is taken as the larger value.

(4) Pool length X

In the case of forward inflow, sufficient pool length is necessary to achieve a generally uniform water flow before reaching the horn pipe. The pool length can be determined according to the layout requirements of the upper structure of the pump room, generally taking (7.0~8.0) D. In the case of lateral inflow, the pool water needs to be appropriately increased or necessary rectification measures need to be taken. The determination of pool length is independent of the size of the inlet diameter of the horn tube used.

(5) Flat shape

The calculation results show that the planar shape of the inlet pool has little effect on the working state of the pump: according to experimental data, the planar shape has a certain impact on the hydraulic loss of the inlet pool, with the heart-shaped hydraulic loss being the smallest and the rectangular hydraulic loss being the largest.

2、 The issues that need to be noted in the design of the inlet pool include:

(1) Make the flow in the inlet pool close to natural flow, and the flow should be able to evenly suction each pump.

(2) The configuration of the pump, the position of the inlet, and the design of the shape of the inlet pool should not cause backflow.

(3) The flow velocity entering the inlet of the water tank should be slow, with a value below 0.7m/s. In addition, it is advisable to maintain a flow velocity of 0.3m/s or less near the pump suction inlet located in the inlet pool.

(4) The flow channel cannot suddenly expand or change direction sharply.

(5) The design size of the inlet pool should not be too large or too small relative to the flow rate of the pump.

(6) Avoid installing another pump upstream of one pump.

(7) There should be sufficient submergence depth to avoid the generation of air intake vortices.

(8) Lower the bottom of the inlet pipe to smoothly connect it to the inlet pool. At the same time, the ends of the inlet and return pipes in the inlet pool should be submerged in the water, which is beneficial for smooth drainage. In this way, the water flowing in from the inlet pipe will not be sucked into the air and flow into the inlet pool.

(9) To prevent the occurrence of vortices, appropriate anti vortex walls and partition walls should be installed.

3、 Reference diagram for closed inlet channel

1. Elbow shaped inlet channel

The elbow shaped inlet channel is commonly used and the design and research are relatively mature. The cross-section of the elbow shaped inlet channel gradually shrinks, and the water flow state inside the channel is good with small hydraulic losses; The width of the channel plane is relatively small, usually B/D=2-2.5 (D is the diameter of the pump impeller, B is the width of the channel). In addition to the insufficient elbow shaped inlet channel, the height of the channel is relatively high, which may increase the excavation depth of the pump station foundation pit. Usually Hw/D=1.6~1.8 (Hw is the vertical distance from the center of the impeller to the bottom of the flow channel), and secondly, due to the complex profile, high construction technology requirements are required.

The main contradiction in hydraulic design of elbow shaped inlet channels is the inability to increase the average angle of water flow into the pump, while the uniformity of flow velocity generally meets the requirements. The geometric parameter that has the greatest impact on the average angle of water flow into the pump is the center height Hw of the pump impeller. Its value should not be too small, preferably not less than 1.6 Do. Without significantly increasing civil engineering investment, it is recommended to use a diameter of 1.8D with an impeller diameter of Do=1m, an impeller chamber inlet diameter of D1=0.97D, and a distance of Hp=0.167D from the center of the pump impeller to the inlet of the impeller chamber. As an example design, for different pump impeller diameters and pump impeller chamber diameters, corresponding conversions can be made based on the ratio of pump impeller diameters.

2. Bell shaped inlet channel
The significant feature of the bell shaped inlet channel is that the center height of the pump impeller (i.e. the distance from the center of the pump impeller to the bottom plate of the channel) is relatively small, which is of particular importance for pumping stations with poor geological conditions. This type of inlet channel was widely used in some large drainage and irrigation pump stations in Japan in the early days, and has also been applied in the construction of large pump stations in China since the 1970s. Compared with elbow shaped channels, the geometric shape of bell shaped channels is more complex, making their hydraulic design more difficult.
The following figure shows the impeller diameter Do=1m and the inlet diameter of the impeller chamber D1=0.97D. The distance from the center of the water pump impeller to the inlet of the impeller chamber is Ho=0.167Do. Design as an example For different pump impeller diameters and pump impeller chamber sizes, corresponding conversions can be made based on the ratio of pump impeller diameters.
