Product overview

My company production of diesel engine fire pump with reference to foreign relevant technical standards requirements development and design. When building a fire, power supply is faulty, electric fire pump will not be put into use properly, this type of fire pump automatically put into operation to make sure fire extinguishing work, to ensure the safety of life and property. This system equipped with various automatic control function, ensure the long-term normal standby unit, ready for the fire fighting work.

Application field

Mainly used in industry, civil construction fixed fire control system (fire hydrant fire extinguishing system, automatic sprinkler system and water spray extinguishing system) of the water supply, in addition, can also be used for fire fighting and life (production) sharing of water supply system and the construction, municipal, industrial and mining, boiler feed water and so on various occasions.

Product features

1, the unit selects the our company produces the high quality multi-stage pump, double suction pump, flow, pressure range, the applicable scope is wide;

2, when the unit receives signals to effective fire or fire pump motor power power supply system, lack of phase, our group can run automatically start;

3, the unit with the function of excellent since the alarm, including multiple launch failure alarm, high water temperature alarm of diesel engine, diesel engine overspeed alarm downtime, low battery voltage, charging failure alarm, fuel lack of instructions alarm;

4, this unit is equipped with manual and automatic startup mode, strong practicability, easy to use;

5, fire signal disappears, the pump automatically delay downtime, and effectively reduce the working strength and cost;

6, diesel, and pumps connected directly, less faults, small vibration;

7, low battery voltage, the unit can automatically recharge, ensure the battery has enough power, double battery circuit design can ensure a battery fails, automatically using another set of batteries; And the battery itself does not need frequent add supplementary fluid, high efficiency and reliable;

8, the capacity and head of the pump with the actual requirements, can be adjusted to change the use of diesel engine speed to meet your requirements;

9, a specially designed preheating system can ensure that the normal boot when the low temperature

10, this unit can run on a regular basis function, to ensure normal standby unit.

The working conditions


Q:How to adjust the flow of piston pump?
For the swashplate valve controlled by the solenoid valve, the swashplate is in an angle with the cylinder body, so the plunger is reciprocating in the pump cylinder when the cylinder rotates. It goes from 0 degrees to 180 degrees, that is, to the upper plunger position, the plunger cylinder volume gradually increased
Q:Is the centrifugal pump large or small?
NPSH is also called cavitation, cavitation is too big to be.3, pump the liquid when working in the impeller inlet will produce vapor due to a certain vacuum pressure, vaporization of the air bubbles in the liquid particle movement under the impact of erosion on the impeller, the metal surface, thus undermining the impeller and other metal, then vacuum pressure is called vaporization pressure, NPSH is excess vaporization pressure of surplus the energy position of the unit weight of the liquid in the pump suction port of. The unit with annotation, (NPSH) r with. The absorption process is necessary NPSH H: pump suction fluid allows the vacuum pump installation height is allowed, in meters.
Q:Why should I pump the pump before starting the centrifugal pump?
Only centrifugal water can be pumped out of the centrifugal blade to generate negative energy at the entrance. There is no water diversion. Only the negative pressure produced by the air is too low to absorb the well water.Water pump has been pumped, centrifugal pump or can not start normally, mostly because of the water pipes and air
Q:Concrete pump 125 pipe wall thickness
Concrete pump diameter 125mm, pipe wall thickness is generally 4mm, also have 4.25mm, 4.5mm, 4.75mm, need to be in accordance with the rules of transport.
Q:Shielding pump is the main drawback of electricity? How much does it cost more than an ordinary centrifugal pump? Is there any noise in the running of the canned pump? How much is it lower than the noise of the common centrifugal pump?
Product featuresThe integrated structure of motor and pump adopts static seal, so that the pump is completely free of leakage;Full closed and no leakage structure, can transport toxic and harmful liquid substances;The shielded water-cooled motor and the cooling fan are removed to make the pump operate in a low noise and quiet condition. The utility model is suitable for occasions with high environmental noise requirements;
Q:Pneumatic diaphragm pump compressed air pressure is 4 kg, the discharge pressure is how big?
Generally slightly lower than 0.4MPa, Zai 0.35Mpa or so, if the outlet is blocked, the outlet pressure will equal 0.4MPa
Q:Roots pump and dry pumpRecently involved in the work of the vacuum pump, don't understand this, is a ads602 vacuum pump, composed of roots pump and dry pump, is pre pumped to the 500mtorr equipment, the main pumping vacuum continues to 10mtorr, where the roots pump and dry pumps must be used? What role they play respectively. The so-called dry pump? Is refers to one kind of the pump, the pump is many dry pump? Also do not understand how the work of automatic switching system for pre pumping, the main pump, pump work alone did not connect system ah (of course there are even a butterfly) teach?
Different working conditions, our company does dry claw pump alone can also achieve the vacuum of 133 PA.
Q:Is the diaphragm pump and the drain pump one?
Therefore, the need to play a liquid discharge pump, if the medium is corrosive liquid, high viscosity, volatile, flammable, highly toxic liquid, you can choose diaphragm pump. Conversely, the general liquid, there is no special requirements, you can use the general centrifugal pump to reduce costs.
Q:What is the function of the heating pump system for the water pump design?
As the feed water temperature is higher, before starting, if not enough to warm the pump, the pump body temperature is uneven, there is a hot, cool phenomenon. The upper part is inflated and the lower part is inflated"
Q:What is the function of a submersible pump?Do you have any knowledge about submersible pumps?.
Important equipment for deep well water extraction. When in use, the whole unit dives into the water. The extraction of groundwater to the surface is water, mine rescue, industrial cooling, irrigation, water lifting, ship ballast, also can be used in fountain landscape, hot water submersible pump for hot spring bath, but also can be applied to the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects. The utility model is mainly used for farmland irrigation and water for human and livestock in mountain areas, and can also be used for central air conditioning cooling, heat pump units, cold pump units, cities, factories, railways, mines and site drainage. General flow can reach (10m3~650m3) per hour, head up to 1500 meters.
