Product Description:

2XZ-BSeries
1. High speed, Iow volume, light weight, equipped with noise reducer, low noise, less shake. Pump stop and oil returnprevention is equipped, so that pupm oil is prevented to get back to the pump once pump stopped working, which makes it easy to restart.2. Gas valve is installed in order to separate the vapor from the gas, when pumping gas mixed with vapor. The valve prohibited the entrance of the vapor, ensured the purity and prolonged the use of the pump oil.3. Vent is applied with oil fog capture mchine to eliminate oil fog when discharge the gas. Ol collecting equipment is installed around the oil sal, in order to preven oil leaking, and entironment pollution.Motor power:0.37~1.5KW,extract capacity2~15L/S,Limit vacuum:2×10-2Pa。

Q:The working principle of magnetic pump
Magnetic pumpBy the pump magnetic pump, magnetic actuators, motors of three parts. The key components of magnetic actuator by the external magnetic rotor sleeve, inner magnetic rotor and non magnetic components. When the motor drives the outer magnetic rotor, the magnetic field can penetrate the air gap and non-magnetic material, driven by the inner magnetic rotor is connected with the impeller for synchronization the rotation, to achieve non-contact power transmission, the dynamic seal into static seal. As the shaft, the rotor is within a magnetic pump, isolated sets of completely closed to completely solve the problem of "run, run, drip, leak, remove the oil refining chemical industry flammable, explosive, toxic and harmful media through the pump seal leakage security risks, effectively ensure the health and safety of workers.
Q:Water pump outlet valve sequence
Design specifications detailed manual instructions, divided into two cases:1, pump water first check valve, suitable for small caliber pipeline, gate valve to protect the non-return valve, not damage function;2, pump water out of the first gate valve, check valve for large diameter pipe, at this point valve easy to open and close;The setting of the check valve is mainly to avoid the high reverse speed of the pump and the condition of the submerged pump house. Set in the suction port of the pump, then stop the pump water flow will still affect the pump. In addition, the pump suction should try to avoid installing too many pipe fittings, so that the pump can maintain sufficient cavitation margin.
Q:Filter backwash pump for what use, what is the principle of work ah?
Regeneration of the filter medium is required to regain the filtration capacity of the medium. The regeneration process is mainly accomplished by the backwashing pump (the backwash pump is not a special pump, referring to the pump for the completion of the process). The working principle is through the cleaning liquid from the downstream of the filter into the backwash pump (alkali, acid and water), reverse flushing filter medium, cleaning liquid discharged from the upstream, this process can be attached to the dielectric surface and internal impurities washed away.
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
Q:What is the pump delivery? What's the difference between years and years?
1) integer integer: ~ batch. Sell ~.2) buy in bulk: ~ goods. Sell now.The exchange is, according to the duration of the contract delivery insurance premium, payment is generally in common, 5 years of insurance you every year that time, continuous call five years; general single sex 5 years or even 10 years of premium.Furthermore, the insurance premium is good or good pay period, if a single rate from the point of view, to make cheaper than single period, but considering the one-time payment of the interest cost of funds and the opportunity cost, there is no difference. While the single cross ratio advantage is mainly reflected in its flexibility. First of all, additional premium may be added to the premium. At present, additional risks can only be covered if the main risks and principal risks are covered during the payment period. The single way to buy insurance, even in the primary insurance protection period will no longer be able to purchase additional insurance new; secondly, to pay the premium can enjoy a premium waiver. If the insured in full payment period has not yet had the danger, not pay part of the premium would be exempt from the Qing dynasty. For child insurance, the premium waiver is more advantageous. If parents unfortunate accidents or illness, resulting in death or one or two, three disabled or suffering from severe illness, the insurance company will be exempted after the premium, the insurance contract shall continue to be valid; finally, to pay the premium or additional premium amount can be changed. The policy holder may adjust his insurance plan according to the change in his economic strength. In contrast, single premium has the advantage of a one-time payment more convenient.
Q:Is the sewage pump the same as the mud pump?
Two of the main performance parameters of mud displacement and pressure, displacement from a number of liters per minute, with the diameter and the drilling fluid requirements from the hole on the back end of the speed, the larger aperture, the greater the displacement. The upstream return speed of the washing fluid is required to remove the cuttings and rock powder from the drill in a timely manner from the bottom of the hole and reliably carry it to the surface. Through drilling and extraction, mud can be obtained at the bottom.Sewage pump is mainly used for industrial wastewater treatment, sewage treatment, environmental protection has played a big role. Among them, the sewage pump is also a sewage pump with cutting wheel, such sewage pump can be chopped dirt, and then extract the sewage clean.
Q:Advantages and disadvantages of canned pumps
The ordinary centrifugal pump is driven by coupling the pump impeller shaft is connected with the motor shaft, the impeller and the motor rotates while working and shielding pump is a kind of non seal pumps, pump and motor is sealed in a medium filled by pumping the pressure vessel, the pressure vessel only static seal and, by a group of wires to provide a rotating magnetic field and rotor drive. The structure eliminates the rotary shaft sealing device of the traditional centrifugal pump, so the utility model can be completely free from leakage.
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.
Q:Pump unloading in hydraulic transmission,
Can be used for short-term shutdown, pump non-stopNo unloading, usually through the overflow valve back to the tank, high pressure, power, at this time insurable pressure, and so on
Q:Why is the sewage pump device coupler?
Advantages of installation and arrangement of sewage pump coupling:1. automatic coupling device, easy installation and maintenance. In the absence of automatic coupling device under the condition of fixed installation, such as pump fault maintenance personnel need to unscrew the screw pump lifting water, repair, or other small pump to pump the water down perfect maintenance, if the water is dirty, it would be difficult for people to go to the next, then the overhaul had great difficulty.
