1) Adjust the pressure of unloading valve DA10, relief valve DB10 or DB20 to the minimum. 2) Check in the slurry inlet valve and close the slurry outlet valve to the minimum, that is, the slurry flow rate of the pump is small at this time.…
The submersible pump series design automatic drainage pits, wells and basements, and extract water from rivers and reservoirs from them. Each submersible pump produces 14 m3/hour and 12 m maximum discharge head maximum flow rate The submer…
High temperature and high pressure cleaning machine working principle of high temperature and high pressure cleaning machine is usually composed of which several parts? In what ways do they play an important role? (I) High pressure plunger…
The deep well pump is a kind of water pump that pumps water from a small deep well. The pump body is partly placed below the water surface in the well, and the power machine is placed at the wellhead. Gubu uses a long transmission uranium …
The introduction of curved shaft piston, such as fan motor driver, is designed for pump, F11 key - 6 series, saw motor, construction machinery. In conjunction with the company's existing F11 key series piston pumps, the F11 - 6 on the comm…
Difference between die casting and die forging blank of vertical fire pumpWhat are the differences between the die casting parts of vertical fire pump and the blank of die casting die forging? Please see the knowledge analysis carefully pr…
Common problems of diaphragm vacuum pump principle The use of chemical reaction instruments such as rotary evaporators, centrifugal concentrators and variety evaporators can not be separated from the function of vacuum pump. People usually…
(l) The application field cooperation is a kind of shell non pressure bearing hydraulic components. The axial piston pump has the advantages of high pressure resistance, high efficiency, large transmission power, wide speed range, long ser…
Performance range:2CY gear oil pump is suitable for conveying lubricating oil with viscosity of 5 × 10-6 ~ 1.5 × 10-3m2 / S (5-1500cst) or other liquids similar to lubricating oil and used in hydraulic rotating system without solid partic…
The plunger pump is an internationally renowned hydraulic brand with hydraulic pumps such as Rexroth, Vickers, Denison, etc. It has many advantages, but even if it is a plunger pump, it is inevitable that some accidents and problems will o…
As an enterprise specializing in the production of sludge pump and sludge pump, we have produced high-quality products, but if we can't sell them, no one knows the excellence of our products, our production will be meaningless, so how to s…
Analysis on the use stage of well furnace There are several stages in the operation of a well furnace: Furnace installation, exhaust and temperature rise:1, after the well furnace to the temperature insulation 0.5~1h, make the temperature …
Hydraulic valves are divided into check valves and reversing valves according to their uses. One-way valve: Only allow the fluid to be connected in one direction in the pipeline, and cut off in the reverse direction. Reversing valve: chang…
There are two reasons for the excessive heating of plunger pump, one is the heat generated by machine friction. Because the active surfaces are in the state of dry friction or semi dry friction, the moving parts rub against each other to g…
The plunger pump is composed of many parts, due to the manufacturing error of parts, improper assembly will likely cause vibration and noise of the hydraulic system Vibration and noise of hydraulic valves hydraulic valve attack noise, due …
Centrifugal pump is a kind of pump that USES the centrifugal action generated when the PR wheel rotates at high speed to change the mechanical energy into the kinetic energy and the pressure energy of water to raise water. It is divided by…
