Among the fire pipeline pumps, they can be divided into vertical fire pumps and horizontal fire pumps according to different installation methods. Many people have doubts about these two common pumps. What is the difference between the two? Shanghai Xizhiquan will explain the difference between horizontal and vertical for you.

Obviously, different installation methods have different floor space. The vertical pipeline pump is installed vertically, and the floor space is relatively small, and the vertical fire pump does not need to lay a foundation, while the horizontal fire pump needs a base.

According to the different structures of the two pumps, it can be concluded that the maintenance difficulty of the two types of fire pipeline pumps is also somewhat different. The maintenance of the vertical fire pump impeller needs to be removed from top to bottom, which is difficult to maintain; the horizontal fire pump only needs to remove the inlet pipe to repair the impeller, which is relatively simple.

Due to the different directions of the water inlet and outlet pipes, the vertical and horizontal pipe connection methods are also different. Since the vertical water pump is a bottom-up structure, while the horizontal fire pump is arranged longitudinally on the base, the motor of the vertical pump and the pump body are connected by sub-ports, while the horizontal pump requires The coupling is used to connect with the motor, and the horizontal pipeline pump needs regular alignment work.

How to install a diesel fire pump is more appropriate?
zjbetter engaged in the design, production and sales of fire pumps for more than a decade, during the service of a variety of companies, enterprises in all walks of life, especially like steel plants, chemical plants, or like hotels, hospitals, such high-rise building projects have been water supply projects, accumulated some experience details, today here to share with you.

That is the installation of diesel engine fire pumps. To run your equipment high efficiency but also save energy, the design and quality of the product itself is very important we all know by heart, but in fact there is an important factor is often easy to ignore, where the diesel engine installation is more appropriate. If the installation is not appropriate, the equipment in operation will be a major headache, vibration, noise, energy consumption, etc..
Diesel fire pumps are suitable for unattended emergency water supply fire fighting systems, with high automation, superior performance and complete protection functions. When a building or factory suddenly loses power and the electricity cannot be supplied, the diesel emergency water supply pump set can automatically start to supplement the pressure of the pipe network. So many customers in the purchase of fire pumps are to follow the principle of "one spare, one use", to electric fire pumps as the main, diesel fire pumps as a supplement. How to install a diesel fire pump?

Generally speaking, we recommend installing a diesel fire pump in a naturally ventilated place, with sufficient size of vents and exhausts, and with vents positioned to ensure sufficient fresh air supply for diesel combustion within the temperature limit. Of course it is also possible to use the water supply radiator to take away the heat from the circulating cooling water and to take away the heat emitted from the surface of the unit. If the space cannot meet the requirements of natural ventilation and cannot dissipate heat effectively, it is recommended that you adopt the method of forced ventilation by adding inlet fans and exhaust fans to the vents, the choice of which should be able to provide sufficient cool air for the diesel engine and at the same time take away the hot air in the engine room. Generally speaking, the air intake of the unit should be 6-7 times the air intake of the diesel engine, as long as this is the case, in order to ensure normal ventilation and improve the operating efficiency of the equipment.

There must also be fixed firmly, which can support the whole unit and ensure that the unit is in a horizontal state to absorb vibration. Generally speaking, the foundation of the unit is made of concrete structure, the length and width of which are 150-250mm on one side of the length and width dimensions of the chassis of the unit, and the depth is 300-600mm, and the height of the ground bolts extending out of the horizontal surface should be about 2 times of the diameter of the bolts. And there should be 750mm of access on both sides of the unit as well as in the front position for the operator's inspection and general maintenance.

The above is some of better's installation experience, I hope it can bring you some help, such as purchasing needs can be in the official website home page contact customer service consulting details.

Diesel engine fire pump, as a large-flow water supply equipment for fire fighting in the new era, can be said to be gradually replacing ordinary fire pumps. No, this company from Singapore traveled thousands of miles to Quzhou to purchase high-quality diesel engine fire pumps.

1, Vertical fire pump, multi-stage sectional structure. The pump inlet and outlet flanges are in the same straight line, the impeller is hydrodynamically balanced, axial force, a guide bearing at the lower end of the pump. The shaft is fixed to the motor shaft by means of a clamping coupling. The outer cylinder is a stainless steel cylinder.

　　2, The shaft seal is mechanically sealed.

　　3, The pump is driven by the motor and rotates in a clockwise direction when viewed from the motor end.

　　4, The pump outlet is equipped with an exhaust valve (air nozzle), which can ensure that the gas in the pump can be completely exhausted.

　　5, The impeller can be made of bronze. Avoid rusting between the impeller and the guide vane after long-term shutdown.

　　

　　I. Installation instructions

　　1. The weight of the pipeline should not be borne on the pump, otherwise the pump will be easily damaged.

　　2. The pump and motor are of integral structure. The pump and the motor are an integral structure. It is calibrated by the manufacturer at the time of shipment, so there is no need to adjust the contract when installing it. This makes installation very easy.

　　3. The foot bolt must be tightened during installation. The pump should be inspected at regular intervals to prevent it from loosening. To prevent the pump from vibrating violently when starting up and affecting the performance of the pump.

　　4. Before installing the pump, check carefully whether there are any hard objects (such as stones, iron sand, etc.) in the flow channel of the pump that may affect the operation of the pump, so as to avoid damaging the overflow parts when the pump is in operation.

　　5. For easy maintenance and safety in use. Install a regulating valve on the pump's throttle and a pressure gauge near the pump's throttle, and for high head pumps. To prevent water hammer. A check valve should also be installed in front of the outlet gate valve to cope with sudden power failure and other loss of power accidents, thus ensuring that the pump operates under suitable working conditions and increasing the service life of the pump.

　　6. The pump is used in suction range situations. It should be equipped with a bottom valve, and the pipeline should not have too many bends in the mouth of the flume, and there should be no water leakage or air leakage in the same inch. To avoid affecting the suction performance of the pump.

　　7, in order not to make impurities burst into the pump and block the flow channel to affect the performance. A filter should be installed in front of the pump's flume.

　　8, the installation of pipeline bary for the rotation of the pump rotor parts, should be no grinding sound or jamming phenomenon, otherwise the pump should be disassembled to check the reasons.
