Shandong Hairui Zhonglian Pump Industry Co. , ltd. The fire pump that is a major produces manufacturer. When type selecting of client fire pump, manufacturer of my company water pump can provide the before-sales service such as price of fire pump model, fire pump, in order to offer client reference, and manufacturer of my water pump can provide the service of product of custom-built pump industry for the client. This product information is the knowledge about point of fire pump type selecting:

It is easy to look for fire pump manufacturer, fire pump is correct type selecting is difficult. Be afraid of type selecting mistake, 2 be afraid of flicker of fire pump manufacturer. A lot of people are about to buy most propbably fire pump has similar mentality. Below small make up integrated industry experience of these a few years, trim point of fire pump type selecting, can consult for everybody and learn!
Fire pump classification:
1, can divide by dynamical source form for: A diesel engineFire pumpFire pump of gasoline engine of D of fire pump of gas turbine of C of B electromotor fire pump;
2, can divide by utility: Fire pump of A water supply fire pump of group B stabilized voltage group C hand carries motor-driven fire pump group;
3, the auxiliary feature of the group that press pump can divide for: A is common fire pump of deep well of B of fire pump group fire pump of group C dive group.
Above is ultimate cluster, but of all kinds between can be united in wedlock each other, fire pump of the low pressure in be like, on any account presses fire vehicle pump, common fire pump group, dynamoelectric dive fire pump the group.
Fire pump type selecting wants a place:
Performance data of 1) fire pump asks
A, common fire pump
Operating mode 1: When sucking deep 1m, should satisfy rated discharge (Qn) and rated pressure (Pn) requirement, at the same time actuating pressure should not exceed 1.05 times of rated pressure;
Operating mode 2: When sucking deep 1m, discharge is 1.5Qn, actuating pressure should not be less than 0.65Pn. Greater actuating pressure must not exceed 1.4Pn.
Fire pump of B, deep well, dive
Operating mode 1: When sucking deep 0m, should satisfy rated discharge (Qn) and rated pressure (Pn) requirement, at the same time actuating pressure should not exceed 1.05 times of rated pressure.
Operating mode 2: When sucking deep 0m, discharge is 1.5Qn, actuating pressure should not be less than 0.65Pn. Greater actuating pressure must not exceed hydrant pump to cross 1.4Pn.
2) construction demand, corrosion resistance can, of the mechanical function, function such as successive movement detect should accord with GB6245-2006 standard requirement.
The pump that place of 3) pump series uses all should pass type approval and type to examine to accord with relevant specification.
Chooses prime mover all should pass type approval and accord with relevant specification. The normal temperature with due and good engine starts function, should assure 5s inside start smoothly. Bring the 20s after sailing upstream inside, should make fire pump achieves rated operating mode.
Impeller of 4) water pump is rotational and agile, without phenomenon blocking block.
5) designs personnel to answer type of the particular case choice of the position according to pump room of the fire control in project project, area and system of fire control water supply, affirmatory fire pump.
The discharge of 6) fire pump and pressure should serve a building according to place (or factory plant area, living village) , the offset such as storage yard, storage tank is waterproof quantity and hydraulic requirement decide via computation. Fire control water pump should satisfy fire control to use water hydraulic ask with discharge. The discharge of water pump, lift does not ask to be worth under the design, also not under function curve set-point.
7) temporarily the fire control water pump of system of water supply of high-pressured fire control should use one equipment to be used, fire pump manufacturer or multi-purpose one equipment. Reserve the working ability of fire pump should not is less than among them bigger working barrel of a fire control. Multi-purpose when one equipment, when paralell connection of fire pump of much stage of Lv of take an examination works, to the influence of system flow rate and pressure.
When 8) chooses fire control water pump, pressure of its discharge ~ (characteristic curve of Q ~ P) should evenness does not have hump. Conditional when can choose tangent pump or pump a powerful person (a powerful person of decompression stabilized voltage) the water pump aircrew of unifinication.
Thank you very much to Shandong Hairui Zhonglian Pump Industry Co. , ltd. The visit of official website! Above is the introduction about point of fire pump type selecting, still think to this problem like you deep one pace understanding, or the problem that has price of model of type selecting of product of other pump industry, water pump, water pump, water pump needs to solve, contact this water pump manufacturer please, my company returns production to suck pump oneself, welcome you at any time seek advice.
