The ZWX box-type non-negative pressure water supply equipment is a pressurized water system designed to address inadequate municipal water pressure in critical settings such as hospitals and hotels, where water cannot be shut off. It also serves as an ideal solution for meeting the domestic water needs of high-rise buildings and, specifically, fulfilling the water requirements of schools. This equipment ensures a continuous water supply, even during maintenance or emergency situations, effectively resolving the challenges posed by low water pressure. With its efficient pressurized water supply and advanced control technology, the ZWX equipment offers stable water pressure and flow rates, catering to the diverse demands of different settings.

The fire water supply pressure booster pump complete sets of equipment is the equipment for the firefighting project. The main function is to maintain the firefighting pressure of the fire extinguishing pipe network. When a fire alarm is opened, the fire extinguishing equipment can immediately spray the solid water column, and the alarm linkage starts the large fire pump. Win the initial fire extinguishing time of more than 30 seconds until the full load of the fire main pump is started. Because the equipment can maintain the pressure of the pipe network at all times, the pipe network does not have air to start. The fire pump does not slam, the pipe network has no risk of vibration.

The most advanced externally mounted PTFE bellows mechanical seal is adopted, which has multi-layer protection and prolongs the service life of the mechanical seal. When conveying the medium containing impurity particles, it can be equipped with single-end hard-to-hard (silicon carbide to silicon carbide) without cooling water. ) mechanical seal, so users need to consider the solid content in the medium when selecting models.

The fire control cabinet is widely used in many high-rise buildings, shopping malls, schools and other crowded places. This equipment enables the fire pump to cut off the circuit or alarm through the components in the fire control cabinet when it fails, and play a warning and The role of protection.

The submersible sewage pump has features such as easy installation and maintenance, high working efficiency, anti-clogging and anti-winding design, which make it an ideal choice for industrial, municipal or commercial waste discharge system, septic tank, piggery, farmland irrigation.

The diesel fire pump system serves as a backup power solution, utilizing a diesel engine to provide power and ensure the fire pump’s reliable operation during electrical outages. The associated fuel tank is a crucial component for storing diesel fuel and providing a continuous supply to the diesel engine, ensuring a sustained water flow during fire incidents.

The domestic water supply equipment system is equipped with storage tanks and other water storage facilities, which saves the floor area and reduces the construction load, thereby saving a large amount of civil engineering investment costs. The intelligent and automatic operation of the equipment does not require a special person to be on duty, which saves management costs, and there is no water quality treatment instrument, which eliminates the need for regular cleaning and disinfection; the loss of system dripping, leakage, and overflow is reduced.

“Fire-fighting gas top-pressure water supply equipment is usually composed of basic components such as air-pressure water tanks, control cabinets, top-pressure gas storage systems, and decompression release devices; in the fire-fighting state, compressed gas is charged into the air-pressure water tank to replace the fire-fighting water storage in the tank. , and always maintain the rated working pressure of fire protection, and the fixed fire water supply equipment that supplies water to the fire pipe network.”

Submersible mixer, also known as submersible propeller, is suitable for promoting and stirring sewage containing suspended solids, dilute mud and industrial process liquid in the technological process of sewage treatment plant, creating water flow, strengthening the stirring function and preventing sludge precipitation. It is an important equipment in the technological process of municipal and industrial sewage treatment.

High efficiency, flat performance curve, wide operating range, in line with the relevant regulations of the fire department, and can meet the needs of different users
Adopt segmented structure, stable operation, low noise, long service life, small footprint, easy installation and maintenance

Centrifugal pump is a blade pump that depends on the centrifugal force generated when the impeller rotates to deliver liquid. In the process of rotating the impeller, due to the interaction between the blade and the liquid, the blade will transmit mechanical energy to the liquid, so that the pressure of the liquid can be increased to achieve the purpose of conveying liquid.

The special hydraulic design and structural design make it more suitable for building fire-fighting water supply system with flow and pressure grading than ordinary centrifugal clean water pumps, and the flow-pressure characteristic curve is flat and has no hump. All parts of the friction parts due to rotation are made of wear-resistant, corrosion-resistant and anti-meshing materials, which have high reliability. The multi-stage pump can be equipped with double water outlets, which has high bearing capacity, strong anti-overload capacity and sensitive starting. .

Non-negative pressure frequency conversion water supply equipment is a new type of water supply equipment developed on the basis of frequency conversion constant pressure water supply equipment.

Sewage pump is a kind of centrifugal impurity, there are two kinds of submersible and dry. It is mainly used for the treatment of industrial sewage and domestic sewage, and has played a great role in environmental protection. In addition, there are also cutting impellers in the sewage pump, which can play a good role in the treatment of various fibrous substances in the sewage.

An “air conditioner pump” is not a common term in the context of air conditioning systems. However, it’s possible that you might be referring to one of the components or aspects related to air conditioning systems. Let me provide some information on components that could be related to what you’re asking:

As the name implies, the fire pump is divided into different types according to different classification methods. It has the characteristics of full sealing, no leakage and corrosion resistance. It is widely used in environmental protection, water treatment, fire protection and other departments to pump various liquids. , It is an ideal pump for creating a leak-free, pollution-free civilized workshop and civilized factory. The pump type is similar to that of the fire protection system, but the lift and flow are different.

The multistage pump is a centrifugal pump in and out of the water section and the middle section, through the rod combination together, its output water pressure can be very large, but also depends on the rotation of the impeller to obtain the centrifugal force, so that the material. When the gas density reaches the working range of the mechanical vacuum pump, it is extracted, and the high vacuum is gradually obtained.

The housing of the diesel engine fire pump constitutes the working chamber of the pump. The impeller, shaft and rolling bearing are the rotors of the pump. Suspension bearing parts The supporting parts support the rotor parts of the pump, and the rolling bearings are subjected to the radial and axial forces of the pump. In order to balance the axial force of the diesel engine fire pump, most pumps have sealing rings at the front and rear of the impeller, and a balance hole on the back cover of the impeller. Because some pumps have little axial force, there is no seal on the back of the impeller. ring and balance hole. The axial sealing ring of the diesel engine fire pump is composed of packing gland, packing ring and packing to prevent air intake or large water leakage.
