PUMPS CUC2-50 50HZ
A centrifugal pump, also known as a pump, is a high-speed directional machine used to move fluids such as water and oil at high speeds. Centrifugal pumps are used in power plants, on ships, and in other applications. They can rotate 1000 times per minute while moving 250 gallons of water per minute if they are in enclosed space and 600 gallons of water per minute if they are outside. The impeller of the centrifugal pump has an expanding sprayer, which causes the pressure to increase by way of the outer walls and reduces pressures by extending kinematics blades during rotation.

What are the types of pumps?
The centrifugal pump relies on the centrifugal force generated by the impeller when it rotates at high speed to throw out the water in the impeller, forming a vacuum state. River water or well water is pressed into the impeller under atmospheric pressure. In this cycle, the water source is constantly thrown out. The adjacent blades of the closed impeller and the inner walls of the front and rear wheel covers form a series of curved blade grooves, which have high pumping efficiency and are mostly used for pumping clean water. The number of open impeller blades is also small, which is mostly used to pump slurry liquid or sewage. Practical centrifugal pumps are divided into single suction and double suction according to the way water enters the impeller, namely B (BA) and S (SH) types. Centrifugal pump impellers are divided into three types: closed, semi-closed, and open. The semi-enclosed impeller has no front cover plate, so it is rarely used at present.
The section of the axial flow pump blade is streamlined, and the blade is twisted, like a propeller. The impellers of axial flow pumps are all open and generally have 2-6 blades. Changing the installation angle of the blade can adjust the water output and head of the water pump. This kind of pump does not need water injection when starting. According to the number of impellers in the axial flow pump, the axial flow pump can be divided into single-stage and multi-stage. According to whether the installation angle of the impeller can be adjusted, the blade can be divided into three installation forms: fixed type, semi-adjustable type, and full adjustable type. When the impeller rotates, it will push the water and make the water in the pipe flow out along the axis.
A masonry pump is also an axial flow pump, which uses a masonry structure and opens a channel outlet tank to replace the cast iron elbow and outlet pipeline of the general axial flow pump. The lift is generally about 1.8m, and the flow is 3780-11 720m ³/ h. It is a kind of water pump with a low head and large flow. It is suitable for waterlogging drainage and saline-alkali land washing in Lake fields and low-lying polder areas. Its model is WZL.
What should we pay attention to when using the water pump?
Check the wear of the shaft sleeve of the pipeline pump on schedule, and replace it in time after the wear is large. Start the pipeline pump motor. When the pipeline pump operates normally, turn on the outlet pressure gauge and the inlet vacuum pump. After it shows appropriate pressure, gradually open the gate valve and check the motor load at the same time. Roll the pipeline pump by hand to see if the guard pump is flexible. Often adjust the packing gland of the pipeline pump to ensure that the leakage in the packing chamber is normal. Close the gate valve, outlet pressure gauge, and inlet vacuum gauge of the outlet pipeline of the pipeline pump. Unscrew the water diversion plug of the pipe pump body and fill the water diversion (or slurry diversion).
If the pipeline pump is out of service for a long time, it is necessary to disassemble all the pipeline pumps, wipe off the moisture, coat the rolling parts and joints with grease, and properly keep them. During the operation of the pipeline pump, the bearing temperature shall not exceed the ambient temperature of 35C and the temperature shall not exceed 80C. The lubricating oil of the pipeline pump shall be changed once every 500 hours after 100 hours within one month before the operation.
Check whether the pipeline pump, pipeline, and joint are loose. If you find that the pipeline pump has abnormal sound, you should immediately park the vehicle and check the cause. Jog the pipeline pump motor to see if the motor rotation is accurate. When the pipeline pump is to be stopped, the gate valve and pressure gauge shall be closed first, and then the motor shall be stopped. Add bearing lubricating oil into the bearing body of the pipeline pump, observe that the oil level should be at the central line of the oil standard, and the lubricating oil should be replaced or supplemented in time. When the pipeline pump is used in cold winter, after parking, it is necessary to unscrew the drain plug at the lower part of the pump body to drain the media to prevent frost cracking. Try to control the flow and head of the pipeline pump within the range indicated on the label to ensure that the pipeline pump operates at the high-efficiency point, to obtain a greater energy-saving effect.
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
