Heat Insulation Pump APPLICATION

*It applies to delivering medium not include solid particles and the temperature not higher than 300°C.

*It also applies to the site with heat insulated requirement in the process technology and outdoors installation at every cold area.

*External gear pump,the tooth form is composite formed by arc and sine curve.Keep warm and cooling the transferred medium and pump.

*Visocity larger than 1500cst,speed should be reduced.

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: Troubleshooting of diaphragm pump: The troubleshooting guide for diaphragm pumps, when encountered in one or more of the following situations, this information can be used as a guide to help you develop maintenance measures.As shown below, some of the abnormal operating conditions described in this guide are: A) fast circulation / low flow B) no cycle / slow cycle / irregular cycle C) leakage D) noise E) component rupture

Q: What is cavitation, centrifugal pump cavitation phenomenon how to solve?: Centrifugal pump cavitation phenomenon how to solve?:Measures to improve cavitation resistance of centrifugal pumps(1) improve the design of the suction port of the centrifugal pump to the impeller. Increase flow area; the radius of curvature increases the impeller cover inlet section, reduce the flow accelerated sharply with pressure; reduce the thickness of the blade, and the blade inlet rounded, close to the streamline, can also reduce the acceleration and pressure flow around the blade head portion of the impeller and the blade inlet part; improve surface finish in order to reduce the resistance loss; the blade inlet edge extends to the impeller inlet, the liquid flow in advance to accept work pressure, improve.

Q: What does "efficiency" mean in a water pump catalog?: Pump efficiency: the ratio of the effective power and the pump shaft power

Q: Rules for operation of centrifugal pumps: Operating rules:1, before starting to check whether the water pump foot loose, coupling shield, and motor fan blade cover is intact, in order to ensure the safety of equipment and personal safety.2. Check whether the inlet valve is open and open as fully as possible. Is the outlet valve closed, open the bleeder valve, exhaust until there is no air, and close the bleeder valve. At the end of the valve to the pipeline in the pump cavity filled with water.

Q: Why is the flow of the pump too small will occur cavitation phenomenon?: This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.

Q: Hydraulic pump displacement refers to the pump shaft what?: Just as you carry a spoon to the water. How much water can you pump at once (every turn)? That's the displacement.

Q: What is the difference between the ground pump and the pump in the commercial concrete?: Move back and forth; pour concrete into a certain area. After the filling is finished, the whole pump truck can be moved to another position quickly

Q: Filter backwash pump for what use, what is the principle of work ah?: When the filter is in normal operation, the impurity will be trapped in the upstream of the filter (filter medium). As the accumulation of impurities, the filter media will be blocked, and the direct performance is that the circulation will decrease. Usually, when the flow drops to a set point (the industry is usually judged by the pressure drop),

Q: How to calculate the motor power of metering pump?: The total mechanical power and hydraulic power, divided by the overall efficiency of pump, and the pump head and the utilization rate of pump mechanical efficiency, and then multiplied by 1.1 times (API675), you can get a metering pump motor need more power.
