The performance of the xbd multi-stage fire pump is as follows: When the pump discharge flow is 150% of the flow rate at the selected operating point, the xbd multi-stage fire pump lift is not less than 65% of the head of the selected operating point, and the lift when the pump is turned off is not Greater than 140% of the selected working point head. The reality is that the performance curve of the xbd multi-stage fire pump is a smooth curve. There are no detailed regulations for xbd multi-level fire pumps in China, resulting in a lot of access to fire pumps. Designers are advised to refer to NFPA20 when designing.
Xbd multi-level fire pump consists of two parts: motor and pump. The motor is Y type three-phase asynchronous motor. The xbd multi-stage fire pump and motor are connected by a coupling. The whole is a rigid connection. No correction is needed when using it. The xbd multi-stage fire pump consists of a stator part and a rotor part. The pump stator consists of the inlet section, the middle section, the guide vane, the outlet section, and the filler box. In order to prevent the wear of the stator, the stator is equipped with a seal ring, a balance sleeve, etc., and the spare parts can be replaced after wear. The rotor part consists of a shaft, a middle wheel, a balance drum and the like. The lower end of the rotor is a water-lubricated bearing and the upper part is an angular contact ball bearing. The majority of the axial force of the xbd multi-stage fire pump is borne by the balance drum, while the remaining part of the residual shaft is subjected to the downward force by an angular contact ball bearing. The joint surface of the water inlet section, the middle section, and the water outlet section is tightly sealed by a paper pad. The user can select according to the need.
The xbd multi-stage fire pump is an indispensable part of the firefighting tool. There are many types of xbd multi-stage fire pumps, and the types used in different fields are also different. However, the xbd multi-stage fire pump is the most common fire engine and fire extinguishing system, and its performance is relatively good. It is not only environmentally friendly but also relatively resistant to corrosion. So how do you manage xbd multi-level fire pumps in your life?
For the electromechanical equipment inside the pump room, professional personnel must be responsible for it. For those who are not allowed to enter, it is dangerous. The signs in the pump room should also be marked so that no errors can occur. Of course, the operator must also be professional, otherwise there may be unavoidable consequences.
For xbd multi-level fire pump and other equipment must be regularly checked to avoid failures affect the normal operation of the equipment, but also to carry out maintenance, only in this way xbd multi-stage fire pump service life will be longer. Xbd multi-level fire pump is very easy to fail without maintenance, cleaning work must be timely, find problems to be resolved in a timely manner, can not delay the normal work.
With regard to the management of xbd multi-stage fire pumps, we hope to help everyone through the above introduction. In addition, the power supply circuit for the pump room also needs to be checked regularly. Before using the equipment, check whether there is any fault, and clean it after use to ensure maintenance measures. This will take longer to use the device.
Xbd multi-stage fire pump xbd multi-stage fire pump product use:
XBD-W type single-stage single-suction xbd multi-stage fire pump is mainly used for fire-fighting system pipeline pressurized water supply. Horizontal xbd multi-stage fire pump can also be applied to industrial and urban water supply and drainage, pressurized water supply of high-rise buildings, long-distance water supply, heating, bathroom, boiler cooling and heating water circulating pressurized air-conditioning refrigeration system water supply and equipment support and other occasions, instead of the original IS type.
Xbd multi-stage fire pump parameters:
Flow: 5-45L/S;
Pressure: 0.18-2.61Mpa;
Power: 2.2-180KW;
Speed: 1450r/min;
Caliber: φ50-φ150;
Temperature range: ≤ 120°C.
"High Regulations" and "Building Regulations" have no testing requirements for the performance of xbd multi-stage fire pump. NFPA20 stipulates that xbd multi-stage fire pump shall have a measuring flow meter on the outlet pipe. The flow meter shall be able to test 175% of the selected flow rate of the pump. The xbd multi-stage fire pump should have a pressure gauge with a diameter greater than 89 mm on the outlet pipe so that the pump can be fully tested after installation to see if it can meet the design requirements. . Designers are advised to consider this issue in their design. The basic principle of xbd multi-stage fire pump is the same as that of common industrial pump. It uses the pressure difference to push the water flow to its own desired height. However, the xbd multi-stage fire pump pays attention to the advantages of efficiency and lift, so it is designed xbd. Multi-stage fire pump must take into account the pump power and good maintenance, because the fire is uncertain, the space and time requirements are relatively high, the xbd multi-stage fire pump should be as efficient as possible in use With large heads, this has a very good effect on suppressing fires.
Of course, in the use of xbd multi-stage fire pump, the use of personnel should also try to avoid debris into the fire tank, it is best to install filters and other equipment in the water inlet, to create a good job for xbd multi-level fire pump work surroundings.
