The jockey pump is a kind of fire pump. It is used to jockey the pressure of the automatic sprinkler system and the fire hydrant water supply system, so that the water pressure of the system is always in the required pressure state. Water volume and water pressure.

All places need to be equipped with fire-fighting facilities, and fire pumps are necessary water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. The fire pumps we commonly use are electric fire pumps and diesel engine fire pumps. The difference between the two is The electric fire pump needs to be supplied by the power system. If the power is cut off, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

Electric fire pumps have a wide range of uses, of course the most important ones are still used in the fire protection industry, and they are also used in water treatment and environmental protection industries. Among these uses, the firefighting profession uses the most. The fire pump is the advantage of fast water pumping that the firefighting profession has fully utilized. Because most of the work of the firefighting profession is to fight fires, the fire pump has played a great role.

1. The fire pump should be capable of supplying the rated flow and pressure for a duration of two hours, at a rate of 150% of the rated capacity, and should not be affected by prolonged operation.

2. The fire pump should be able to start up automatically by a power source when activated.

3. All switches, gauges, alarms, controllers and monitoring systems should be certified to UL and FM standards.

4. The fire pump should be sized to meet the NFPA 20 standard for fire pump design.

5. The fire pump should be able to handle the maximum system flow and pressure required for the building.

6. The fire pump driver should match the requirements of the pump and meet NFPA 20 requirements for fire pump drivers.

7. The fire pump should be installed according to NFPA 20 standards for fire pump installation.

8. The fire pump should be tested and inspected in accordance with NFPA 25 standards for testing and inspection of fire pumps.

Discuss the importance of regular fire pump testing to ensure system readiness in case of an emergency. Describe weekly churn tests and annual flow tests, explaining how these tests verify the pump’s performance, check for potential issues, and maintain compliance with NFPA and insurance requirements. Include a checklist to make testing straightforward and encourage record-keeping.

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 general fire water supply environment is equipped with one electric and one diesel fire pump as the reserve water pump to ensure sufficient emergency water consumption. The main components of the electric motor fire pump set are the motor and the pump body. The subdivision of the pump body is the pump casing, impeller, pump shaft, bearing, coupling, sealing form, water pipe, etc. The specific fire pump model is determined according to the environment and performance requirements. At the same time According to the material quotation required by the customer, accurate selection is conducive to on-site use and reduces failure problems.

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.
