2. mechanical seal, it is safe to install and maintain;

3. motor shaft and the pump shaft linked directly by a coupler;

4. ss304 material adopted for the water flow parts, won’t pollute the medium transported;

5. durable and beautiful

6. low noise and standard design for wide use.

Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: (1) pump connected outside pipes, containers, pipes, joints and other leakage test instrument, large leakage, rotary gas plug exhaust sound big, and the gas and oil mist discharge, should find leakage cancellation.(2) the assembly of rubber of intake pipe is not proper, damage or aging should be adjusted or replaced.(3) plug hole, the vacuum degree can be decreased, put the oil, remove the tank, loosen the nozzle plate, pull out the oil inlet nozzle, dredge oil hole, try not to use cotton wipe parts.(4) the vacuum system has serious pollution, including containers, pipes and so on. It should be cleaned.(5) the spring of the vane is broken and should be adjusted.

Q: Troubleshooting of diaphragm pump: The ratio of flow to water weight at a specific weight of --68F. 68F water has a specific gravity of 1Static suction head - the vertical distance from the liquid level to the central line of the pump. The pump shall be above the level of the liquid.Vapor pressure the pressure of all the steam on the free surface of the liquid. In any pump operating system, the operating pressure shall not be lower than the vapor pressure, otherwise the steam will be partially or completely cut off into the pump fluid. Viscosity - because of the presence of friction in the fluid, the property of viscosity gives the fluid resistance to flow.Water hammer action -Water hammer is a sudden power failure, or in the valve closed too fast, due to pressure, flow of inertia, produce water shock waves, like hammer hammer, so called water hammer. The force produced by the flow of water shock waves can sometimes be very large, thereby damaging the valves and pumps. Water hammer effect refers to the inside of the water pipe, the pipe wall is smooth, flow freely. When the opening of the valve suddenly closes, the flow of water to the valve and the tube wall, mainly the valve, will produce a pressure. As the pipe wall is smooth, the subsequent water flow in the role of inertia, the fastest reach the maximum and damage, which is the water conservancy "water hammer effect", that is, "positive water hammer.". This factor should be taken into consideration in the construction of water conservancy pipelines. On the contrary, the valve closed in a sudden opening, it will produce water hammer, called negative water hammer, but also a certain destructive power, but not the former big.. Causes and treatment methods of common failures of diaphragm pumps:

Q: The function of centrifugal pump: The basic structure of the centrifugal pump is composed of six parts, namely: impeller, pump body, pump shaft, bearing, sealing ring, stuffing box.1, the impeller is the core part of the centrifugal pump, it is high speed, large output, the impeller blade and play a major role in the impeller before assembly, through the static equilibrium experiment. The inside and outside surfaces of the impeller are required to be smooth, so as to reduce the friction loss of the water flow.

Q: What does "anti pump" mean in pump operation?: The working process of the main oil cylinder pushing back and forth against the pump when the S valve (C valve or valve or gate valve skirt) reverse swing, so the piston suction concrete cylinder is in the ash conveying pipe is exactly opposite is the pump suction pump (hopper is concrete and push into the hopper, the desizing)

Q: There are second cutting, third cutting, why three times?: So some pumps are written in the back of XXXX-125A or B, that is, the impeller nominal diameter is 125, A is through a cut, B is the 2 cutting. To reach the applicable conditions, only the calculation is not enough, but also after cutting to test to determine.

Q: What are the basic technical parameters of the pump?: The effective power of pump and output power, with Pe said. It is the effective energy per unit time from the pump in conveying out liquid obtained in the pump. Because the lift refers to the effective energy, pump output unit of heavy liquid obtained from the pump so that the product of head and the mass flow rate and the acceleration of gravity. Is to obtain the output from the pump in unit time of liquid effective energy - efficient pump power: Pe= P gQH (W) = QH (W) - P - density of liquid pumping (kg/m3); severe gamma - pump for transporting liquid (N/m3) - Q (pump flow; m3/s; H) - pump head (m); G (m/s2). The acceleration of gravity P axle power and effective power Pe is the difference of power loss in the pump, the size of the pump efficiency to measure the efficiency of the pump. As the effective power and shaft power ratio, with ETA said. Selection of related pumps:

Q: How accurate is the metering pump?: Three automatic compensation valve device widely used in diaphragm metering pump, especially with suction height requirements, can only be used by three separate Fujian (safety valve, discharge valve and oil supply valve) compensation device.

Q: Does the control cabinet of the fire control pump need to be related to the fire control room?: Automatic sprinkler, which is mostly used in this device or high water tank, the whole set of equipment must meet the most unfavorable point (the farthest the highest point of water) water pressure of the faucet.

Q: How to maintain and repair the booster pump of pipeline pump?: Installation and use1. use rubber washer and bolt to connect the pump flange at both ends and the pipe flange. In order to use and maintenance convenience, in the pump inlet and outlet pipelines should be installed with a regulating valve.2. open the inlet control valve, so that water into the pump, in order to keep the cavity filled with liquid (otherwise it will damage the seal), close the outlet valve.3. turn on the power and make sure the correct turn.4. make sure the pump starts and runs after turning.5. adjust the opening of the outlet valve so that the pump runs near the design point, depending on the rated flow and lift of the pump. [for this reason, it is better to place a pressure gauge near the outlet flange). Note: this pump is strictly prohibited to run without water, so as not to damage the seal.

Q: Why adjust the centrifugal pump outlet valve can adjust the flow? What are the advantages and disadvantages of this method? Is there any other way to regulate the flow of the pump?: The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
