Introduction to stainless steel gear pumps
The two gears of the stainless steel magnetic pump have different shapes and different numbers of teeth. One of them is a ring gear, which can float in the pump body, and the middle one is a driving gear, which is eccentric to the pump body. The number of ring teeth is one more tooth than the driving gear. The driving gear drives the ring gear to rotate together and uses the change in the space between the two teeth to transport liquid. There is another kind of internal stainless steel. The ring gear has two more teeth than the driving gear. A fixed crescent-shaped partition is installed between the two gears, which obviously separates the suction and discharge space. In the case of the same discharge pressure and flow rate, the external stainless steel gear pump has smaller dimensions than the external stainless steel gear pump.
Stainless steel pump material selection can be divided into: 304, 316, 316L, polymer materials, PTFE, nylon and so on. The more suitable stainless steel gear pumps can be selected according to the medium condition of the stainless steel gear pump.
Why is stainless steel corrosion resistant? All metals react with oxygen in the atmosphere to form an oxide film on the surface. Unfortunately, the iron oxide formed on ordinary carbon steel continues to oxidize, causing the corrosion to continue to expand and eventually forming holes. You can use paint or oxidation-resistant metals (such as zinc, nickel and chromium) for electroplating to ensure the surface of carbon steel, but, as people know, this protection is only a thin film. If the protective layer is damaged, the steel below will begin to rust.
There are mainly two common situations:
1. When stainless steel pumps are used to transport flammable and explosive media such as toluene, gasoline, diesel, ethanol, from the perspective of explosion protection, copper gears are generally used for gear pump gears. The main purpose is to prevent the gear pump from sparking during the transportation process. However, stainless steel gear pumps are considered from the perspective of anti-corrosion. In some cases, copper materials cannot be used or the medium conveyed in some cases has no lubricity, so the life of the gear pump will be reduced. After the technical improvement of our company, the new generation of stainless steel gear pump is really specially designed for explosion-proof and non-lubricating medium. The gear adopts PTFE polymer material, which not only solves the explosion-proof performance of stainless steel gear pump, but also improves the gear resistance of stainless steel gear pump. The grinding life greatly improves the overall service life of the gear pump.
2. For stainless steel gear pumps to transport highly corrosive media, 316 and 316L stainless steel materials should be used.

Everyone knows that the bearing of a gear pump is an important hub connecting the pump and the motor. The maintenance and repair of the bearing is also very important. Let me introduce it to you.
Water pump bearing-repair of sliding bearing:
Repair of bearing bush: The bearing bush of sliding bearing is the most prone to wear or burn out. Generally speaking, if the wear, scratches, spalling and melting of the bearing alloy surface are greater than 25% of the bearing contact area, the bearing alloy should be re-poured.
The measurement method of the gap between the journal and the bearing bush: The gap between the journal and the bearing bush is generally measured by the pressure lead wire method. When measuring, first place the bearing’s lower half bearing on both sides of the plane and the top of the journal. Diameter 1- 1.5mm fuse, then close the upper bearing bush and bearing cover, tighten the bearing cover with bolts and then open the bearing cover, take out the squashed fuse, and measure its thickness with a micrometer (usually measure 3-5 points along the length of the fuse) Its average).
Grinding and scraping of the bearing bush: When grinding and scraping the bearing bush, a layer of red lead oil should be applied to the pump shaft first, and then the pump shaft should be placed in the bearing bush to rotate two times, and then the pump shaft will be taken out. Even small black spots. These small black dots indicate the higher part of the bearing bush, which should be gently scraped off with a scraper. Then, repeat the above steps until the small black spots shown on the surface of the bearing bush are evenly dense. When grinding, the bearing bush should be scraped off first, and then the bearing bush should be scraped on.
Water pump bearing-repair of rolling bearing:
The average service life of rolling bearings is generally about 5000h. If they are used for a long time or improper installation and maintenance, the bearings will be damaged. If it is found that there are cracks in the inner and outer rings of the rolling bearing, the balls are broken, and the gap between the balls and the inner and outer rings is measured with a feeler gauge of 03mm exceeding the regulations, new bearings should be replaced.
If the inner ring is tight or the rotation is not flexible enough, it may be that the cage of the ball is deformed and twisted and mechanical friction is caused by the bearing ring. At this time, you can tap the cage with a hand hammer to correct the deformed part.
If there is rust on the surface, it can be wiped off with fine sandpaper, then washed and dried.
The pump shaft and the inner ring of the bearing are tightly matched. Generally, the press-in method is used. If there is difficulty, the heating method can be used.
Internal gear pump consists of a rotor ad idler. Liquid travels between them through “gear-within-a-gear” principle. Pump head forces the liquid to move out of discharge port. A seal is formed between the discharge and suction ports. This pushes liquid out of the discharge port.
There are two kinds of valves for gear safety protection: safety valves and regulating valves. Both of these are safety protection valves. What is the difference in actual use? Let me introduce it for everyone.
When the pressure is too high, the gear pump safety valve will jump; the pressure regulating valve can be set to a pressure, when it is higher than this pressure, the valve opens, when it is lower than this pressure, the valve closes. In this case, is the regulating valve equivalent to a safety valve? Is there a big difference in performance?
Safety valve is a safety design adopted for a single equipment or pipeline. When the pressure is too high, it will automatically trip to restore the pressure to the normal operating value. At the same time, it plays a protective role to prevent the equipment from being damaged or accidents due to excessive pressure caused by excessive pressure. Regulating valve, as its name implies, is a regulating function. It plays a role in regulating and controlling process parameters. Its purpose is to stabilize or regulate one or several upstream or downstream temperature or pressure or flow rate or liquid level point and other parameters!
The gear pumps safety valve is to protect the pipeline or equipment, the pressure is super high, and it is used for pressure relief.
The pressure regulating valve is to keep the downstream pressure stable, mainly to ensure the stability of the downstream flow.
In a word, the gear pump safety valve is to maintain a stable pressure before the valve.
The regulating valve is to maintain the pressure after the valve is stable, the two cannot be interchanged!
The safety valve can automatically open and close according to the working pressure of the system, and is generally installed on the equipment or pipeline of the closed system to protect the safety of the system. When the pressure in the equipment or pipeline exceeds the set pressure of the safety valve, the pressure relief is automatically opened to ensure that the pressure of the medium in the equipment and pipeline is below the set pressure to protect the equipment and pipeline from accidents. The regulating valve is used to regulate the flow, pressure and liquid level of the medium. According to the signal of the adjustment position, the opening of the valve is automatically controlled to achieve the adjustment of the medium flow, pressure and liquid level. In general, the safety valve is only opened in an accident state, and theoretically requires physiological verification after opening, while the regulating valve is opened to adjust the flow or pressure in the normal state.
Gear pump safety valve-set a pressure point, the pressure will jump immediately when the pressure is high, it is mainly used in emergency situations and is usually closed.
pressure regulator-set a pressure point where the upstream pressure is higher than this pressure and it maintains the downstream pressure. The problem is usually open!

High-precision gear oil pump seal leakage, first check whether the selection and installation of the seal are correct, and secondly check whether the working conditions are running smoothly. In the structure, a number of original hydraulic balance technologies are adopted, and the GZYB high-viscosity gear oil pump has high efficiency when working under high pressure. , Low noise, stable operation, long pressure holding time and other unique properties. The reasons for the leakage of high-precision gear oil pumps and prevention measures are adopted in the structure of a number of original hydraulic balance technologies. GZYB high-viscosity gear oil pumps work at high pressure High time efficiency, low noise, smooth and stable operation, and long pressure holding time.
1. The gland is installed incorrectly, and the drain holes on the front cover and the rear cover are blocked.
2, the outer diameter of the seal ring and the aperture of the seal seat are too loose.
3, the direction of the pump body is reversed, so that the pressure oil port is connected to the unloading groove, and the pressure is formed to flush out the sealing ring.
4, the oil quality is not clean, and the oil return is not smooth.
5, the thread of the tubing is not tightly matched.
As an important part of the high-precision gear oil pump, the seal of the high-precision gear oil pump plays the role of fixing the main shaft and sealing medium. If there is a leakage, first check whether the seal selection and installation are correct, and secondly check whether the working conditions are running smoothly.
The Saiken Brand kcb Series Gear Oil Pumps is horizontal positive displacement gear pump. These pumps use two identical gears rotating against each other, the drive gear operates the idler gear. Liquid flows into the cavity of the teeth and is directed and pressurized toward the discharge port by the gear rotation.
The flow characteristics of a diaphragm pumprefers to the relationship between the relative flow of the medium flowing through the valve and the displacement (relative opening of the valve). The ideal flow characteristics mainly include straight line, equal percentage (logarithm), parabola and quick opening. The curve and spool shape are shown in Figure 1 and Figure 2. The commonly used ideal flow characteristics are only straight line, equal percentage (logarithmic), and quick opening. The parabolic flow characteristic is between straight line and equal percentage. Generally, equal percentage characteristic can be used instead. Quick opening characteristic is mainly used in two-position adjustment and program control. Therefore, the choice of diaphragm pump characteristic is actually linear and equal percentage flow characteristic s Choice.
The selection of the flow characteristics of the diaphragm pump can be calculated theoretically, but the methods and equations used are very complicated. At present, empirical guidelines are mostly used, specifically considering the following aspects: ①Analyze and select from the adjustment quality of the regulation system; ②Consider from the process piping situation; ③Analyze from the load change situation.
By choosing the flow characteristics of the Air diaphragm pump, the shape and structure of the valve core can be determined according to its flow characteristics. However, due to their structural characteristics, such as diaphragm valves and butterfly valves, it is impossible to change the curved surface shape of the valve core to achieve the desired result. The required flow characteristics can be achieved by changing the shape of the feedback cam of the valve positioner.
The Pneumatic air operated diaphragm pump design makes it suitable for use in a wide range of industries: Waste water Petrochemica Food and beverages Pharmaceutical Mining and construction Printing, paint and ink
