Q:Operating procedures for measuring pumps
start-up1. Adjust the stroke indication to zero by adjusting the nut or handle with the rotary stroke.2 open the outlet valve.3. Open the inlet valve, pump, exhaust from the high point, exhaust from the relief valve, the breather valve.4, point motor, check the operation of the pump.5. Start the motor.6, without pressure on the premise, every 15 minutes to improve the stroke 20%, if there is no pressure, do not substantially improve the stroke.Note: (1) whether the sound or vibration of the pump is abnormal (2), whether the stroke adjustment is automatic or not
Q:What is a vacuum pump for?
You are not confused by different names. It is mainly used in folding machines, paper cutting machines and water treatment aeration
Q:Centrifugal pumps for normal operation, is it reasonable to install valves on their inlet lines?
Reasonable, no valve, how to debug, overhaulGenerally installed on imports of valves of relatively large Cv value
Q:Common failure treatment of piston pump
x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck
Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same
Non negative pressure variable frequency water supply means no negative pressure superposed water supply equipment. When running, it is connected directly to the water supply pipe. Always test the pressure of tap water pipe network and water supply pipe network pressure control system, when the water pressure is lower than the pressure required by the user, the frequency conversion device based on water automatically control the pump speed through the steady flow compensator of water balance, maintain a constant pressure water supply. In the multi pump system, the control system can automatically dispatch the water pump according to the water consumption. It can balance the working time of the pump and ensure the pressure of the water supply. When the water supply pressure satisfy the required pressure, the system automatically stops the pump by the external water supply pipe network directly. CJWFG-DYG non negative pressure superposed water supply system:
Q:What are the application areas of pumps?
Performance range from the pump to see giant pump flow up to hundreds of thousands of cubic meters per hour, while the micro pump flow per hour in a few milliliters; pump from atmospheric pressure up to 19.61Mpa (200kgf/cm2); the lowest temperature of the liquid is transported up to -200 DEG C, up to 800 DEG C. Pumps carry a wide variety of fluids, such as water (clean water, sewage, etc.), oils, acid and alkaline solutions, suspensions, and liquid metals.In the chemical and oil sector production, raw materials, semi-finished products and finished products are mostly liquid, and semi-finished and finished products to raw materials, need to go through a complex process, to pump and provide transportation of liquid chemical reaction of the pressure and flow in the process, in addition, the device also used in many pumps to adjust the temperature.In agricultural production, the pump is the main irrigation and drainage machinery. Rural areas in our country are vast and vast, and a large number of pumps are needed every year in rural areas. Generally speaking, agricultural pumps account for more than half of the total output of pumps.Pumps are also the most widely used equipment in the mining and metallurgical industries. The mine needs pumping and drainage. In the process of ore dressing, smelting and rolling, the pump needs water to supply water first.
Q:What do you mean by the self coupling device on the pump?
Auto is an installation of the pump, which comprises a pedestal, self coupling frame, a guide rod and a guide rod support, the bottom fixed coupling frame, vertical installation of two guide rods can easily be brought down without installing the pump, the pump at the bottom of the pool, the outlet of the pump and the discharge tube can automatically lock, don't need to bolt connection, automatic coupling position, so as to achieve the effect of simple and convenient. When you need to repair, pump the pump up without jumping into the sink.
Q:Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
(three) infusion limited number of pills produced after the dose of obstruction by infusion pump and specification of the matching test, will reach acceptable when the storage pressure of the pressure to determine the alarm blocking. Thus, some have restrictions on the infusion tube blocked after the maximum dose pill may have blocked the trigger before the alarm.
Q:The main factors affecting the performance of centrifugal pumps
The low specific speed pump, on the other hand, is suitable for smaller flow and higher lift. When the pump outlet pipe diameter at the same time, if the two pumps flow similar, smaller than the speed of small head, shaft power consumption is also large. Generally speaking, the centrifugal pump with smaller revolutions than the impeller has a narrow outlet width and a large outer diameter, and the channel formed by the blade is narrow and long. If the ratio of revolutions is large, the impeller outlet is wide and the outer diameter is small, then the flow passage is short and wide.I hope my answer will be helpful to you. I hope to adopt it!
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:
