what is the difference between fire pump and spray pump?

2020-08-28
Fault one: multistage centrifugal pump does not absorb water, pressure gauge and vacuum gauge needle beat violently

Reasons: 1. Insufficient perfusion water diversion; 2. Air leakage at the connection of pipeline and instrument; 3

Solution: 1. Check whether the bottom valve leaks water. Rehire sufficient water diversion 2. Tighten air leakage 3. Reduce water absorption

Fault two: multistage centrifugal pump does not absorb water vacuum gauge shows high vacuum

Reasons: 1. The bottom valve is not opened or blocked; 2. The suction pipe has too much resistance; 3

Solution: 1. Check the bottom valve; 2. Replace water absorption; 3. Clean the filter

Fault three: pressure gauge pressure but still not water

Reasons: 1. Too large resistance of outlet pipe; 2. Wrong rotation direction; 3. Impeller blocking

Solution: 1. Check or roulein pipe 2. Check motor. 3. Open the outlet valve 4. Clean the dirt in the impeller

Failure four: the design flow cannot be reached

Reasons: 1. Air inhalation 2. Due to water level reduction. The submersion depth is not enough; 3. There is a foreign body in the impeller that is blocked; 4

Solution: 1. Check the air leakage part and remove it; 2. Extend the suction pipe. Deepen the submersion depth 3. Remove and drip foreign matter 4. Replace the sealing ring

Fault five: pump consumption power is too large

Reason: 1. Packing is too tight. Excessive flow; 3. Friction between the rotary body and the housing; 4. Wear of the pump bearing; 5. Pump shaft bending

Solutions: 1. Relax the packing pressure properly; 2. Close the opening of the gate valve; 3. 5. Replace or calibrate bearings

Fault six: pump vibration increased

Reasons: 1. Partial blockage of impeller 2. Impeller damaged 3. Too small flow 4. Pump shaft and motor different center 5. 6. Mixed with air. Cavitation occurred

Solution: 1. Remove foreign body; 2. Replace impeller; 3. Slightly open outlet valve 4. 5. Change the suction position. Improve the suction

 

Fire pump is involved in a variety of fire system water supply of the special pump collectively. The fire pump model starts with XB. Fire pump must be tested and approved by relevant national units before it can be used on various fire control systems of buildings, such as: fire hydrant system, sprinkler system, foam extinguishing system, high-altitude water cannon in large space, water mist extinguishing system, rain spraying extinguishing system, water curtain, etc.

General design and construction of a single fire pump refers to the fire hydrant pump, sprinkler pump and hydrant pump is only in the system for different purposes, in fact, all attributed to the fire pump, the difference is different parameters (flow, head, power, etc.), this is because the system set fire hydrant system and sprinkler system flow, pressure is different. If from the structure, function, there is no difference. Humidity sensor probe, stainless steel heat pipe, PT100 sensor, cast aluminum heater, heating ring, fluid solenoid valve.

Spray pump is a kind of fire pump.

Fire pump sprinkler pump, hydrant pump, pressure regulator pump, etc.

Fire pump: it is the general name of the water pump supplying water to the fire system.

Sprinkler pump: It is a water pump that supplies water to the automatic sprinkler system.

Hydrant pump: A pump that supplies water to a hydrant fire extinguishing system.

Pressure regulating pump: it is a pump to replenish water to fire hydrant fire extinguishing piping system or automatic spraying fire extinguishing piping system to maintain the pressure of the piping system.
