Product Description:

development of pump energy saving products.Self-priming centrifugal pump, the pump and other pump does not have the self-priming capacity, etc.Such as corrosion resistant mechanical seals and stainless steel material can call some of the chemical, pharmaceutical acid and alkali medium. 
Second, the product features
 
1, the pump with self-priming function, do not need to install the bottom valve in pipeline, only to ensure storage in pump body before work are quantitative liquid can have "a drainage, life-long self-priming" function.So both simplifies the pipeline system, and improved the working conditions.
2, has a compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life. 
Three, use the product
 
1) suitable for urban environmental protection, construction, fire control, chemical, pharmaceutical, dyes, and dyeing, brewing, electric power, electroplating, papermaking, oil, mining, equipment cooling, tanker unloading, etc. 
(2) apply Yu Qingshui, sea water, chemical liquid medium with acid, alkalinity and with general mushy slurry (medium viscosity 100 mile, or less under the solid content of 30%). 
(3) mount a rocker arm sprayer, the water can go into the air, a small drips to spray, is a good tool for farm, nursery, garden, tea garden. 
And (4) can be matched with pressure filter of any model and specifications, sending size belt filter to filter the most ideal auxiliary pump.  
Fourth, working conditions
 
Traffic: 3 ~ 500 m3 / h
Head: 10 ~ 80 m
Ambient temperature 50 ℃ or less
Medium temperature is 100 ℃ or less
Medium density of 1.24 or less by 103 kg/m3

Q:Is the vacuum pump air compressor?
A vacuum pump is a device or device that uses a mechanical, physical, chemical, or physical chemical method to pump a vacuum from a container to be evacuated. Generally speaking, a vacuum pump is a device that uses various methods to improve, produce, and maintain a vacuum in a confined space.
Q:What is the difference between centrifugal pump and positive displacement pump?
Positive displacement pump is the volume pump, this type of pump is to rely on changes in volume to compress fluid work, including: diaphragm pumps, gear pumps, screw pumps, etc.;
Q:Brief description of centrifugal pump on / off operation
(3) check whether the turning rotor is easy and flexible, check the pump body is clang or friction sound.(4) the protective cover is installed, and the shield contact.(5) clean the pump frame and do a good job of sanitation.(6) open the inlet valve, make the liquid full of pump body, open the vent valve, clean the air and close it. If the hot oil pump, it is not allowed to open the air valve exhaust, to prevent hot oil channeling spontaneous combustion, if there is a dedicated vent pipes and tanks, you can vent the pipe line air and cold oil.(7) the hot oil pump should be preheated slowly before starting. Especially in winter, the pump body and the pipe should be preheated at the same time, so that the temperature difference between the pump body and the conveying medium is below 50 centigrade.(8) the oil must be sufficiently dehydrated before being introduced into the oil pump.
Q:Why is the submersible pump tripped on an electrical switch?
Submersible pump cable or motor insulation is damaged.3) motor water solution
Q:What are the general water pump failure, how to repair?
Two, pump speed is low(1) human factors. Some users because of original motor damage, may be accompanied by another motor, resulting in a flow of small, low head or even the consequences of Sheung shui.(2) the mechanical failure of the pump itself. Impeller and pump shaft fastening nut loose or deformation of the pump shaft bending, resulting in multi impeller, directly with the pump body friction, or bearing damage, are likely to reduce the pump speed.(3) the maintenance of the power machine is not working. The motor is lost because of winding burn, the change of winding number, wire diameter, wiring method, or failure in maintenance can not change the pump speed.
Q:What is the difference between an air pump and a water pump?
Pump performance of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?
The choice of pressure depends on the size of the load and the type of equipment. Consideration shall also be given to the assembly space, the economic conditions and the availability of components for the actuators.In the case of a certain load, low working pressure, is bound to increase the structure size of the actuator on some devices, the size must be limited, from the perspective of material consumption is not the economy; on the other hand, the pressure to choose too large, the pump, cylinder, valve and other components of the material, sealing and manufacturing accuracy requirements very high, must raise the cost of equipment.
Q:What kind of motor does the hydraulic pump need?
Calculation of actual oil pump power:First count the flow: Q=dn L / minD displacement / revN RPM / minThen calculate the actual power: N=QP/ (60K) kwQ flow L / minP MPa MPaK total efficiency (usually 0.85)I do not know what the landlord said, 2.5L is the displacement or flow at the end, the concept must not be confused
Q:How should the water pump be installed?
Installation method of hydraulic pump(1) according to the technological requirements and the cavitation conditions of the pump, the installation height check and the civil engineering of the foundation are carried out.(2) prepare a series of flat washers and wedge gaskets of different thickness before installation.(3) according to the characteristics of the pump conveying medium, determine the material of the gasket at the connection and process the gasket.
Q:What is the lift of diaphragm pump?
Hello, pneumatic diaphragm pump head is liquid, the energy obtained through the pump is called the head, it is related to the flow rate and pump speed, liquid density.Please adopt.
