1000gpm EJ pump set

In the fire fighting pipeline pump, according to the different installation methods can be divided into vertical fire pumps and horizontal fire pumps, many people have questions about these two common pumps, what is the difference between the two? Shanghai Xizhiquan will explain the difference between horizontal and vertical pumps.

Obviously, different installation methods take up different space. Vertical pipeline pumps are installed vertically, covering a relatively small area, and vertical fire pumps do not require a foundation, while horizontal fire pumps need to be equipped with a base.

According to the different structures of the two pumps, it can be concluded that there is also a certain difference in the ease of maintenance of the two types of fire fighting pipeline pumps. The impeller of the vertical fire pump needs to be dismantled from top to bottom, which makes maintenance more difficult; the horizontal fire pump only needs to have the inlet pipe removed so that the impeller can be overhauled, which is relatively simple.

Due to the different inlet and outlet pipe directions, the pipeline connection between vertical and horizontal is also different. As the vertical pump is a bottom-up structure, while the horizontal fire pump is longitudinally arranged on the base, so the motor of the vertical pump and the pump body are connected in the form of sub-mouth connection, while the horizontal pump needs to use couplings to connect with the motor, and the horizontal pipeline pump needs to be corrected regularly.

Diesel engine fire pumps are relatively common in life, and their performance requirements are relatively high. In ordinary use, more attention should be paid to maintenance, so as to prolong the service life of the pump. Because diesel fire pumps are not omnipotent, there will be some problems in daily use, so when choosing equipment, we must pay attention to whether the quality of the equipment meets the national standards. As fire equipment, all kinds of equipment must be To ensure performance, avoid affecting use in disaster situations and delaying rescue.

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in the case of no power supply or abnormal power supply and other emergencies, other diesel engines can also be equipped as power engines according to the needs of users.

Fire water pump refers to the water supply pump used to ensure the system pressure and water volume in the fire water supply system. The fire pump transfers energy to the water through the rotation of the impeller, thereby increasing the kinetic energy and pressure energy of the water, and transporting it to the fire extinguishing equipment to meet the water volume and water pressure requirements of various fire extinguishing equipment. Such as fire hydrant pumps, sprinkler pumps, fire transfer pumps, etc.

Diesel fire pumps are generally used as backup equipment, and will only start automatically when the fire signal arrives, the electric pump fails or the power is cut off. After the ultra-low pressure starting device is equipped, the matching electric water pump control cabinet should also be equipped with an ultra-low pressure starting device, and the pressure difference between the two should be the lower limit. This series of products has a large range of lift and flow, which can fully meet the needs of the dock , warehouse, liquefied gas station, petrochemical, airport, power plant, textile and other industrial and mining enterprises fire water supply.

First of all, check whether the oil level is normal and cannot reach the oil mark line on the normal surface. If it is not, we must replenish it in time, but remember one thing, it cannot exceed the amount of the oil quantity indicator line.

Secondly, check the radiator. The water is appropriate. If it is not added in time, the water that needs to be added must be clean water, as long as it is clean water, or tap water is fine. Why not use groundwater, because impurities in groundwater can easily form scales in the water tank, which affects the cooling effect and is also prone to failure. In winter, we drive to preheat the car, add coolant to the car, and the fire pump is no exception. The weather in the north is very cold, so add the coolant to the fire pump according to the actual temperature.

Finally, check the installation of each part of the fire pump, such as whether they are stable, the connection between the screw and the screw, if there is any looseness, tighten the screw in time. To clean the fire pump, soak a canvas or dry cloth and wipe slowly on the body or on surfaces made of grease or dust.

The EDJ Fire Pump Set includes diesel engine pumps, electric pumps and jockey pumps.

Fire pumps are primarily designed for structural fire protection, and their use in wildfire prevention is limited. However, water pumps and other firefighting equipment may be employed for vegetation fire control in specific situations.

The diesel engine fire pump can form an automatic water fire water supply system with electric pumps and jockey pumps, and can be linked with the fire control center.
When the diesel engine fire pump set receives the starting command, if the mains power is cut off, the automatic control cabinet of the diesel engine will immediately send a start signal to the starting motor of the pump set, start the motor, start the diesel engine at idle speed, and then gradually adjust the throttle to accelerate the diesel engine until Rated speed. The control system will automatically monitor the operation of the diesel engine, such as the oil pressure, oil temperature, speed of the diesel engine, outlet pressure of the water pump, etc., and determine whether the diesel engine starts normally through automatic monitoring. If the start fails, the control system will send a restart signal, and if the three starts fail, the automatic control system will send a failure alarm. When the diesel engine fire pump set receives a signal that the pressure of the pipe network is restored or the mains power is restored to normal, the pump set will quickly slow down and stop automatically after monitoring the idle position for a period of time.

An additional protective cover is added to the outdoor fire pump, which can protect against rain, sun, and rust to a certain extent.Heat exchange cooling, low noise，Hydraulic brace，Independent suspension system.Able to deal with harsh environments with good quality assurance

The fire pump can be installed in multiple ways according to the on-site use conditions. And depending on the flow and head requirements, the required flow and head are increased in parallel and series. The bearing adopts low-noise closed bearing, which has been injected with grease before leaving the factory, which can ensure continuous operation for more than two years, and the components have high concentricity. The pump impeller has good performance. Dynamic balance, no vibration in operation, and improved use environment. The pump shaft seal is a mechanical seal, which solves the serious leakage of conventional centrifugal pump packing, increases the service life, and ensures that the operating site is clean and tidy.

The parts that may cause friction when the pump rotates are all made of wear-resistant, corrosion-resistant and high-anti-seize material combinations to ensure reliable operation, reduce noise, and avoid rust water, blocking spray and other fire-fighting devices, extending service life and after shutdown. Rust bite phenomenon.

The conventional electric pump is the main pump, the diesel engine pump is the backup pump, and the jockey pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive the pressure gauge from the electric contact. When the signal comes, the diesel engine pump will be started within 5 seconds, and the rated working condition will be reached within 20 seconds to ensure the normal operation of the fire extinguishing work.
