Nov 28, 2022What kind of environment to choose what kind of water pumpThis problem, in short, is the selection of water pumps. The following are the relevant steps for you to choose water pumps from zjbetter. I hope they can help you choose water pumps and help you better. Choose the water pump that suits your project.
1. Confirm the use environment
First understand the environment in which the equipment is used, including temperature, humidity, air pressure, air corrosiveness, dustproof and waterproof requirements, and the level of hazardous areas.
2. Confirm operating conditions
Refers to the liquid surface pressure (absolute) on the suction side of the liquid, the liquid surface pressure on the discharge side, intermittent or continuous work, fixed or mobile position, and the convenience of installation and maintenance.
3. Confirm the nature of the medium
Medium temperature, density, viscosity, saturated vapor pressure, solid particle diameter and content, gas content, corrosiveness, volatility, explosiveness, toxicity.
4. Select the material of the pump wetted parts
According to the physical and chemical properties of the pumped medium above, the material of the flow-passing parts is determined.
5. Determine performance parameters
The performance parameters of the water pump can be determined by calculation, analogy, test and other methods.
6. Determine the installation type
The installation of the pipeline is determined by the layout of the pipeline and the installation site, and there are direct connection, vertical and other types.
8. Determine the number of pumps
In general, spare pumps, especially fire pumps, are set up, and the number of pumps is selected according to different situations.View details -
Nov 25, 2022What kind of fire pump equipment is guaranteed in fire safety management?
Fire protection is very important to people's life, which is related to the safety of people's lives and properties. In order to ensure people's fire safety, the government not only has 119 fire alarms, but also has higher requirements for the fire fighting equipment systems of various units. A set of safe and qualified fire-fighting equipment can save people's lives in such critical moments as a fire. The fire pump is a kind of either use it or not, once it is used, its value is far beyond its own. So what fire pump equipment is the safest and most secure?
We all know that when a fire occurs, various situations may occur, the circuit may be damaged, and the equipment may malfunction temporarily. In order to deal with these unexpected factors, fire pump manufacturer zjbetter has developed and produced a relatively safe and guaranteed The equipment, yes, is the fire pump unit.
The main feature of the fire pump set is that it has two kinds of power control, which are diesel engine and electric motor. The electric pump set is put into operation when the mains power is normal. When the power supply fails and the electric fire pump cannot be put into use normally, the diesel engine fire pump set will be put into operation automatically to ensure the supply of fire water. The diesel engine fire pump set can also be equipped with various automatic fire pumps. Function, meet the requirements of the standard, ensure the long-term normal standby state of the equipment, and put it into fire fighting work at any time. The two power supply methods are more reliable to ensure the fire water supply in case of fire emergency.
Zjbetter fire pumps have a wide range of applications, and are suitable for various fire hydrants, sprinkler fire main pumps, fire booster pumps, various villas, residential areas, industrial and civil buildings and other fire protection systems, as well as various oil depots, oil loading and unloading Ports, logistics parks and other places with high fire protection requirements.View details -
Nov 25, 2022What must be paid attention to when using long-axis fire pumps and diesel engine fire pumps
The long shaft fire pump is the choice of many customers and plays an important role in people's fire safety. Of course, in order to better play its role, as well as better use and maintain the water pump, some precautions about the long-axis fire pump still need your attention.
Since the fire pump plays a very important role and is related to people's fire safety, when some problems occur during use, it must be paid attention to, so as not to delay the normal use of the fire pump, so that it cannot be started in time when a fire occurs, and the fire extinguishing time is delayed. . When a problem is found, it must be repaired immediately to eliminate the fault and ensure that the equipment is safe and effective before it is put into use, so as to better ensure people's fire safety.
The packing seal is an important part of the water pump. During the use of the fire pump, it is necessary to pay attention to the condition of the packing seal regularly and add it in time, otherwise it will affect the sealing performance of the water pump. Once the fire pump causes water leakage, it will directly affect the power consumption of the motor of the equipment, which will greatly increase the power consumption and damage the impeller of the equipment.
When the equipment generates strong vibration during operation, it is necessary to stop the operation of the equipment, check and repair the fire pump, and eliminate the problem, so as not to cause greater damage to the pump.
Secondly, the impeller is also a relatively important part in the water pump, and the condition of the impeller should be paid attention to regularly when the water pump is running. Regularly check whether there are cracks on the impeller of the water pump, and pay attention to the rust of the impeller. The cracks or rust of the impeller may cause damage and lead to the normal operation of the pump. In addition, in the daily maintenance of the fire pump, it is also necessary to pay attention to whether the fixing of the impeller is loose. At the same time, the mud needs to be repaired regularly to avoid blockage and affect the operation of the pump.
When using a long-axis vertical fire pump, there are still many things that need to be paid attention to. In order to better maintain the water pump and prolong its service life, daily professional maintenance is very important. Shanghai Xizhiquan is a professional fire pump manufacturer. The company produces a complete range of equipment, including fire booster and voltage regulator equipment, diesel engine fire pump sets, single-stage one-stage multi-stage fire pumps, fire control cabinets, etc. Since its establishment 19 years ago, the company has accumulated rich experience in pre-sales and after-sales, guaranteeing high-quality services for customers.View details -
Nov 25, 2022Which fire pump should be selected for the fire water supply system of high-rise buildings?Fire protection system is a necessary equipment for all buildings, enterprises and public places.
