The fire pump is the heart of the entire fire protection system, and it is very important to pump fire water with quick start and continuous and reliable operation. Choosing a fire pump with reliable quality and daily maintenance is very important in fire fighting work. In daily use, fire pumps often encounter various common problems, such as vibration, abnormal noise, and high temperature. A series of problems, why the fire pump heats up, and the measures we should deal with. We all know that fire pumps have cooling systems, which are divided into manual and automatic. The working prin

The regulated fire pump is a common equipment in modern fire protection systems, including regulated water pump units, pressure tanks, control cabinets, pipes, valves, measurement and control instruments and other accessories. The equipment is often interlocked with fire water supply pumps, such as fire pipe network, fire sprinkler pipe network, and fire hydrant pipe network, which are jointly used for fire water supply. The stabilized pressure pump set adopts alternate operation mode. After being put into the fire-fighting operation state, the fire-fighting stabilized pressure pump set stops

Self-priming pumps are a very common category of water pumps, especially many customers who have sewage needs while transporting water, often choose to buy self-priming sewage pumps. But how to judge the performance of a self-priming pump, if you have no criteria for judging this part before purchasing, or if you are confused and don’t know how to use the equipment better and more efficiently after purchasing, you can get a general understanding from this article Let’s take a look at the factors that affect the operating efficiency of self-priming pumps. After learning and analyzing, we can f

Diesel engine fire pump start is divided into manual mode and automatic mode. In manual mode, it needs to cooperate with the control cabinet to start and stop operations. In automatic mode, the start is remote operation, and the stop also needs control cabinet operation. 1. Description of the control cabinet Diesel engine fire pump control cabinet has start button, stop button, diesel engine acceleration button, diesel engine deceleration button, instrument panel displays oil pressure, speed, water temperature; there are also power indicator light, operation indicator light, stop indicato

An excellent and easy-to-use diesel engine fire pump must not only have excellent quality, but also carry out strict daily and phased maintenance, so that the fire pump can be kept in good condition and ready to enter the state at any time, so that it can respond to emergencies. Put out the fire in time. Daily maintenance 1. It is necessary to keep the appearance of the fire pump clean and tidy, the connection of the pump body and its supporting equipment is in good condition, the rotating parts are flexible, the oil circuits, circuits and instrument connectors are firm and reliable,

The fire pump is a special pump installed on fire trucks, fixed fire extinguishing systems or other fire fighting facilities, and used to deliver liquid fire extinguishing agents such as water or foam solutions. According to whether there is a power source, it can be divided into fire pump without power source and fire pump group. Non-power source fire pumps can be divided into: vehicle fire pumps, marine fire pumps, engineering fire pumps, and other fire pumps according to the use occasions; according to the outlet pressure level, they can be divided into: low pressure fire pumps; mediu

The model of the fire pump is formulated according to relevant laws. After identifying the model of the fire pump, it is necessary to understand how the model of the fire pump is formulated. The model of the fire pump is composed of five parts: pump characteristic code, main parameters, purpose characteristic code, auxiliary characteristic code and enterprise custom code. The pump feature codes include CB vehicle fire pump, JB hand-held motor fire pump, HB marine fire pump, TB other fire pump, etc.

Single-suction pump, also known as end-suction pump, has the advantages of stable operation, simple structure, simple repair and maintenance, convenient installation and small footprint. The single-suction pump has low cost, reasonable price and wide application. The flow rate of the single-suction pump is smaller and the flow rate is equal. The volume of the single-suction pump is smaller, but the axial force is large and the bearing load is large. End suction pump: The end suction pump works by rotating the impeller to make the water produce centrifugal motion. Before starting the centri

What is a mobile pump truck? In fact, this kind of pump truck is a piece of equipment for disaster relief. It needs to be stored for a long time, lack of maintenance, and be able to operate under harsh conditions. Therefore, this kind of pump truck can actually deal with emergencies that occur under special circumstances. For example, when the sudden event is characterized by urgency, suddenness, and difficult operation, this pump truck can cope with these situations well. Why is the mobile emergency drainage pump truck so easy to use? All this is due to the advancement of equipment techno

How to prevent the fire pump cavitation? First, from the perspective of prevention, we recommend to open the recirculation pipe when the feed water flow is reduced to a certain extent, so that a part of the feed water flow will return to the deaerator, then there will be enough water in the pump to pass the pump. carry away the heat generated by the friction, keep at a certain temperature from rising to vaporize the feed water.

What is the cause of the water leak of fire pump? How to solve it? 1. The fire pump sealing ring loses its elasticity due to long-term use. At this time, the sealing ring can be taken out, and cut another piece of paper or cloth with a thickness of 0.3 to 0.5 mm into a pad slightly larger than the original sealing ring and install it in the groove, then install the original sealing ring.
