Through adopting cooling method, it can transport media with higher temperature if necessary, and is applied to transport various corrosive media or media in which pollution is forbidden similar to water in such industries as chemical industry, petroleum, metallurgy , electric power, papermaking, food, pharmacy and synthetic fiber etc.
High pressure fire fighting pump structure
1. QI model pumps are the series of products designed according to ISO international standards in all industries in China. It is mainly composed of pump body, impellers, seal rings, impeller nuts, pump cove r, seal parts, intermediate support, spindle, suspended parts and so on.
2. Structural features : the pump cover is fixed on the intermediate support, and the pump cover is clamped in the middle by coupling between pump body and intermediate support. On the pump body, water is input axially and output radially. Support feet can be fixed on t he bas e directly . The suspended parts are fixed CZPT the intermediate support through the rabbet, and are supported CZPT the base by suspended frame
3. Rotation direction: the pump is driven by motor directly through a prolonged coupling, seen from the side of the motor, it rotates clockwise.
4. Spindle seal patterns: spindle seal patterns o f pump are of 2 types such as stuffing seal and mechanical seal. The stuffing seal is that on stuffing casein pump cover , with software stuffing for sealing, input water of a certain pressure into the stuffing case, for cooling, lubrication and cleaning on seal; mechanical seal is of 2 types such as single-surface mechanical seal and double-surface mechanical seal, input water of a certain pressure into the seal chamber, for washing and cooling on the abrased surfaces.
Seal patterns of pump are of stuffing seal or mechanical seal, according to users’ requirements, in a same time, seal chamber sizes and shaft gland patterns of other structures according to ISO3069 as required, are allowed, such as mechanical seals of corrugated pipes, assistant impeller seals and so on

How to Identify a Faulty Drive Shaft
The most common problems associated with automotive driveshafts include clicking and rubbing noises. While driving, the noise from the driver’s seat is often noticeable. An experienced auto mechanic can easily identify whether the sound is coming from both sides or from 1 side. If you notice any of these signs, it’s time to send your car in for a proper diagnosis. Here’s a guide to determining if your car’s driveshaft is faulty:
Symptoms of Driveshaft Failure
If you’re having trouble turning your car, it’s time to check your vehicle’s driveshaft. A bad driveshaft can limit the overall control of your car, and you should fix it as soon as possible to avoid further problems. Other symptoms of a propshaft failure include strange noises from under the vehicle and difficulty shifting gears. Squeaking from under the vehicle is another sign of a faulty driveshaft.
If your driveshaft fails, your car will stop. Although the engine will still run, the wheels will not turn. You may hear strange noises from under the vehicle, but this is a rare symptom of a propshaft failure. However, you will have plenty of time to fix the problem. If you don’t hear any noise, the problem is not affecting your vehicle’s ability to move.
The most obvious signs of a driveshaft failure are dull sounds, squeaks or vibrations. If the drive shaft is unbalanced, it is likely to damage the transmission. It will require a trailer to remove it from your vehicle. Apart from that, it can also affect your car’s performance and require repairs. So if you hear these signs in your car, be sure to have it checked by a mechanic right away.
Drive shaft assembly
When designing a propshaft, the design should be based on the torque required to drive the vehicle. When this torque is too high, it can cause irreversible failure of the drive shaft. Therefore, a good drive shaft design should have a long service life. Here are some tips to help you design a good driveshaft. Some of the main components of the driveshaft are listed below.
Snap Ring: The snap ring is a removable part that secures the bearing cup assembly in the yoke cross hole. It also has a groove for locating the snap ring. Spline: A spline is a patented tubular machined element with a series of ridges that fit into the grooves of the mating piece. The bearing cup assembly consists of a shaft and end fittings.
U-joint: U-joint is required due to the angular displacement between the T-shaped housing and the pinion. This angle is especially large in raised 4x4s. The design of the U-joint must guarantee a constant rotational speed. Proper driveshaft design must account for the difference in angular velocity between the shafts. The T-bracket and output shaft are attached to the bearing caps at both ends.
U-joint
Your vehicle has a set of U-joints on the driveshaft. If your vehicle needs to be replaced, you can do it yourself. You will need a hammer, ratchet and socket. In order to remove the U-joint, you must first remove the bearing cup. In some cases you will need to use a hammer to remove the bearing cup, you should be careful as you don’t want to damage the drive shaft. If you cannot remove the bearing cup, you can also use a vise to press it out.
There are 2 types of U-joints. One is held by a yoke and the other is held by a c-clamp. A full ring is safer and ideal for vehicles that are often used off-road. In some cases, a full circle can be used to repair a c-clamp u-joint.
In addition to excessive torque, extreme loads and improper lubrication are common causes of U-joint failure. The U-joint on the driveshaft can also be damaged if the engine is modified. If you are driving a vehicle with a heavily modified engine, it is not enough to replace the OE U-joint. In this case, it is important to take the time to properly lubricate these components as needed to keep them functional.
tube yoke
QU40866 Tube Yoke is a common replacement for damaged or damaged driveshaft tubes. They are desirably made of a metallic material, such as an aluminum alloy, and include a hollow portion with a lug structure at 1 end. Tube yokes can be manufactured using a variety of methods, including casting and forging. A common method involves drawing solid elements and machining them into the final shape. The resulting components are less expensive to produce, especially when compared to other forms.
The tube fork has a connection point to the driveshaft tube. The lug structure provides attachment points for the gimbal. Typically, the driveshaft tube is 5 inches in diameter and the lug structure is 4 inches in diameter. The lug structure also serves as a mounting point for the drive shaft. Once installed, Tube Yoke is easy to maintain. There are 2 types of lug structures: 1 is forged tube yoke and the other is welded.
Heavy-duty series drive shafts use bearing plates to secure the yoke to the U-joint. All other dimensions are secured with external snap rings. Yokes are usually machined to accept U-bolts. For some applications, grease fittings are used. This attachment is more suitable for off-road vehicles and performance vehicles.
end yoke
The end yoke of the drive shaft is an integral part of the drive train. Choosing a high-quality end yoke will help ensure long-term operation and prevent premature failure. Pat’s Driveline offers a complete line of automotive end yokes for power take-offs, differentials and auxiliary equipment. They can also measure your existing parts and provide you with high quality replacements.
A U-bolt is an industrial fastener with threaded legs. When used on a driveshaft, it provides greater stability in unstable terrain. You can purchase a U-bolt kit to secure the pinion carrier to the drive shaft. U-bolts also come with lock washers and nuts. Performance cars and off-road vehicles often use this type of attachment. But before you install it, you have to make sure the yoke is machined to accept it.
End yokes can be made of aluminum or steel and are designed to provide strength. It also offers special bolt styles for various applications. CZPT’s drivetrain is also stocked with a full line of automotive flange yokes. The company also produces custom flanged yokes for many popular brands. Since the company has a comprehensive line of replacement flange yokes, it can help you transform your drivetrain from non-serviceable to serviceable.
bushing
The first step in repairing or replacing an automotive driveshaft is to replace worn or damaged bushings. These bushings are located inside the drive shaft to provide a smooth, safe ride. The shaft rotates in a rubber sleeve. If a bushing needs to be replaced, you should first check the manual for recommendations. Some of these components may also need to be replaced, such as the clutch or swingarm.
