PUMPS BJZ100 - horizontal pump
Submersible pumps are a great product for water extraction. They can be used to pump water from deep underground, which is a useful tool for farming as well as spa centers. The submerged pump can handle all of these tasks. In addition to the ability to extract water forcefully, it features an efficient and quiet design that blends well with any environment.
The submersible water pump can be used for many different applications. Many spa centers use it for water extraction, and many farmland irrigation uses it to extract groundwater.

Basic parameters of the pump
The parameters characterizing the main performance of the pump are as follows:
Flow Q
Flow is the volume (volume or mass) of liquid delivered by the pump in unit time.
The flow is expressed in Q, and the unit is m3/s, m3/h, l/s.
Lift H
Head is also called "head". Lift is the increment of energy per unit weight of liquid pumped by the pump from the pump inlet to the outlet. It is usually expressed in H, and the unit is m.
The head of the pump represents the performance of the pump itself, which is only related to the energy of the liquid at the inlet and outlet flanges of the pump, but not directly related to the pump device. However, using the energy equation, the pump head can be expressed by the energy of the liquid in the pump device.
In general, the head of the horizontal centrifugal pump is bounded by the center line of the pump shaft. One side of the axis is a suction pipe, which sucks up the water, and the other side of the axis sucks out the water pressure through the outlet pipe. The height at which the water pump draws water up is called the suction head, which is referred to as the suction head, and is represented by the symbol h suction; The height at which the water pump can pump out the water pressure is called the water pressure head, or the head, which is indicated by the symbol H. Therefore, the pump head is the sum of the suction head and outlet head.
That is, h=h suction +h outlet
Speed n
Speed is the speed of the pump shaft per unit time, represented by the symbol n, and the unit is r/min. Generally speaking, the pump with a small caliber has a high speed, while the pump with a large caliber has a low speed.
Power
The pump power PA usually refers to the input power, that is, the power transmitted by the prime mover to the pump shaft, so it is also called shaft power, expressed in PA.
The shaft power PA of the pump shall be obtained by measuring the speed and torsional torque, or by measuring the known efficiency directly connected to the pump η The input power PA of the motor (prime mover) is determined. Known motor efficiency η The shaft power PA of the mot pump is:
Pu = Pa X η
The effective power of the pump is also called output power, which is expressed in Pu. It is the effective energy obtained by the liquid delivered from the pump in unit time.
Because the lift is the effective energy obtained from the pump by the unit weight liquid output by the pump, the product of lift, mass flow, and gravitational acceleration is the effective energy obtained from the liquid output from the pump in unit time - the effective power of the pump.
Pu= γ QH/1000= ρ gQH
Where, if the unit of liquid gravity is kg/m3, then Pu= γ QH/102
Efficiency
Efficiency is the efficiency of water pump transmission power, which is the ratio of the effective power of the water pump to shaft power. Efficiency is an important technical and economic index of the water pump. With symbols η express.
Because there are mechanical, volumetric, hydraulic, and other losses in the pump, the effective power of the pump are always smaller than the shaft power. Therefore, the smaller the power loss in the pump, the higher the efficiency of the pump. On the contrary, the greater the power loss in the pump, the lower the efficiency of the pump. The calculation formula is η= Pu/Pa.
Application field
① In the production of chemical and petroleum sectors, most of the raw materials, semi-finished products and finished products are liquids, and the production of semi-finished and finished raw materials into semi-finished products and finished products needs to go through complex technological processes. During these processes, pumps play a role in transporting liquids and providing pressure flow for chemical reactions. In addition, in many installations, pumps are used to adjust the temperature.
② In agricultural production, pumps are the main irrigation and drainage machinery. my country's rural areas are vast, and a large number of pumps are needed in rural areas every year. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most used equipment in the mining and metallurgical industries. The mine needs to be drained by pumps, and in the process of beneficiation, smelting and rolling, pumps are needed to supply water.
③ In the power sector, nuclear power plants need nuclear main pumps, secondary pumps, and tertiary pumps, and thermal power plants need a large number of boiler feed pumps, condensate pumps, oil and gas mixing pumps, circulating pumps, and ash pumps.
④ In national defense construction, the adjustment of aircraft flaps, tail rudders and landing gear, the rotation of warships and tank turrets, and the ups and downs of submarines all require pumps. High pressure and radioactive liquid, and some also require the pump without any leakage.
⑤ In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or everyday life, pumps are needed everywhere, and pumps are running everywhere. That's why the pump is listed as a general-purpose machine, which is a major product in the machinery industry.
⑥ Electric pumps, i.e. pumps driven by electricity. The electric pump is composed of a pump body, a water lift pipe, a pump base, a submersible motor (including cables) and a starting protection de
