PUMPS CVL1 50HZ
Water pumps are the most common and simple equipment in the central vacuum cleaning system. They use water to drive the vacuum suction, which is mainly composed of there type: gear pump and centrifugal pump.
A gear water pump is a simple design. It can be made out of plastic, metal or mixed materials. The gear pump does not need a maintenance lubricant and uses little electricity so it's very energy efficient to run.
When the pump is rotating, it will fill water into the pump body quickly and achieve self-suction. The fast rotation of the bearing makes it easy to suck water from all directions into the pump.

Types of Water Pump and Their Advantages
Gear water pump
The teeth of the two sprockets are separated. Apply a little pressure and the water is sucked in and sent to one side through the friendly circular wall on the other side. The two gears are pushed together to create high pressure and drain the fluid.
Advantages: simple and compact structure, small size, lightweight, good manufacturability, low price, strong self suction.
Centrifugal water pump
The pump is filled with water, the pump shaft rotates violently, and the centrifugal force makes the water faster. Features, high efficiency. The pump efficiency can be improved by analyzing and calculating the relationship between the pressure distribution and the velocity distribution in the pipeline.
It is convenient for installation and maintenance and adopts vertical pipe design. The inlet and outlet of the pipe can be placed as valves at any position and direction along the pipe.
The motor shaft is directly connected with the water pump shaft. Stable, safe and reliable operation.
Multistage centrifugal pump
This is equivalent to continuous rotation of several centrifugal pumps and single-stage strengthening. The difference between multistage centrifugal pump and single-stage pump and single-stage pump is that multistage pump has two or more valves, which can absorb and compress water to reduce water in the process. The water level can be raised to a very high position by increasing or decreasing as needed.
This kind of pump is mostly used for urban and industrial water supply, and rarely used for agricultural irrigation. Compared with one-way centrifugal pump, the efficiency is improved. Compared with piston pumps, diaphragm pump and other reciprocating pumps, it can also carry higher flow.
The multi-stage centrifugal pump has the highest efficiency and can meet the requirements of high altitude and large flow conditions. It is widely used in petroleum, chemical industry, electric power, construction and fire protection. And other industries.
Variable frequency water pump
This type of water pump is clean and tidy, and the equipment is sealed, without bacteria or dust entering the system. Prevent algae growth and prevent secondary water pollution and water pollution. Users can save energy by using tap water that meets the national health standards.
Fully integrated structural performance, built-in multivariable negative pressure water supply system.
Suitable for swimming pools, sewers, disinfectants and showers. It is directly connected in series with the pipeline network, which makes it possible to optimize the initial water supply pressure to have an impact.
When the water supply meets the requirements, the equipment will stop working. In most cases, variable-frequency pumps operate at low frequency and consume the least energy.
Usually, regular maintenance of water pumps is an important measure to avoid small defects turning into big defects and small problems turning into big problems, which is to create conditions for prolonging the service life of units, improving the integrity rate of the equipment, and saving energy. Regular maintenance includes local maintenance, unit overhaul, and extended overhaul.
Maintenance method of water pump:
- Local maintenance. Generally, it is arranged in a planned way during the operation interval or winter maintenance period. Local maintenance items mainly include.
1)Inspection and treatment of copper sleeve and oil sleeve of full regulating water pump regulator.
2)Inspection of guide bearing of centrifugal pump. The wear condition, water leakage, and journal wear of rubber bearings shall be checked, recorded, and handled. Most of the oil guide bearings are Babbitt alloy steel bearings, which are soft and easy to wear. For example, if the sealing effect is not good, water enters the oil basin during the shutdown, sediment settles, and the bearings and journal are worn during operation. In particular, carbon steel journals that are not sprayed or coated with stainless steel should be regularly inspected and treated in order to understand their corrosion and wear.
3)Check and inspect thermometers, instruments, relay protection devices, etc.
4)Upper and lower guide bearing oil grooves and turbine oil sampling and testing.
5)Check the clearance and surface of the bearing bush. According to the temperature of the thermometer during operation, check the bearing bush clearance and shaft surface purposefully.
6)Check and handle the braking part.
7)Whether the fasteners of all parts of the unit, such as foundation bolts, shaft keys, and locating pins, are loose.
8)Check the appearance of the oil cooler and pass the water test to see if there is leakage.
9)Check the cavitation and sediment abrasion of the impeller, blade, and impeller shell, and measure and record the degree.
10)Measure the clearance between the blade and impeller housing.
- Unit overhaul. It is a planned management work to recover the technical condition of the unit through an overhaul. The first damage to the unit is accident damage, and the probability of occurrence is very small. Second, normal damage, such as friction and wear during operation, cavitation damage, and sediment wear, has a very small probability. The second is normal damage, such as friction and wear, cavitation damage, sediment wear, vibration caused by various disturbances, the effect, and corrosion of AC stress, electrical insulation aging, etc.
- Extensive overhaul. When the pump room causes the unit axis to offset and vertical concentricity change due to uneven foundation settlement, etc; Or the parts are seriously worn and damaged, resulting in a serious decline in the performance and technical and economic indicators of the unit, the whole machine must be disassembled, repeatedly repaired, replaced, adjusted and partially transformed.

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
