◊ Application

RS Series vacuum pump is compact, light and attractive in design. It uses the big starting torque and is specially designed for low temperature environment. It is guaranteed start normally in winter’s low temperature. It is applicable to vacuum packaging, vacuum freez

This kind of pump is widely used in food packaging, scientific research, medical treatment, electronics, chemicals, medicine and laboratory of universities and colleges.

ing, automobile reparation, gas analysis, medicine mechanism, printing mechanism and other vacuum evacuations.

◊ Technical data

◊ Products' picture

Q: Rotary vacuum pump does not meet the requirements of vacuum, what are the reasons?: 1) oil rotary vane vacuum pump is too low, no effect on the oil seal exhaust valve, rotary plug to refuel after large exhaust sound, and oil mist, that the level is too low, the gas can be eliminated.(2) the vacuum caused by the condensable steam pollution of oil should be changed, and new vacuum pump oil should be replaced.

Q: Must the water pump in the tank be all soaked in water?: Usually you have to soak it all in the water. If you don't want to put it in the water, you can buy an amphibious pump. At most, you can expose it

Q: What is double hydraulic pump?: The 2 pumps are all coaxial connected together, driven by a motor, the general gear pump, piston pump

Q: What are the application areas of pumps?: Water pump has different uses, different transmission liquid medium, different flow, lift range, therefore, its structure form is not the same, the material is also different, summed up, can be roughly divided into:

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: Operating procedures for measuring pumps: First, preparation and inspection before starting1. Check to make sure that the drain line is equipped with a safety valve with the correct set pressure.2. Check the screws for the liquid end parts.

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: The working principle of magnetic pump: Control of cooling fluid flowThe pump is running, you must use a small amount of liquid in the magnetic separation between the rotor and the casing annulus area and sliding friction bearings for flushing cooling. The cooling liquid flow pump design flow is usually 2%-3%, the annular area between the magnetic rotor and sleeve of eddy current generated because of high heat. When the cooling and lubrication the liquid is not enough or poor flushing holes to plug, will result in permanent magnet medium temperature is higher than the operating temperature of the inner magnetic rotor gradually loses magnetism, the magnetic actuator failure. When the medium is water or water-based liquid, can make the annulus area temperature maintained at 3-5 DEG C; when the medium or hydrocarbon oil that can make the annulus area temperature maintained at 5-8 degrees.

Q: Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?: The power of axial flow pump decreases with the increase of flow rate, and it is a steep curve, so the centrifugal pump starts with an open valve.

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),
