Experts Analyze The Reasons For The Failure Of The Pressure Pipeline System

Experts Analyze The Reasons For The Failure Of The Pressure Pipeline System The experts of the withholding machine manufacturer will analyze some faults in the pressure pipeline for us today, and analyze the reasons for the faults. The hydraulic pipeline system of construction machinery is the power transmission system of the main engine of construction machinery, which can be described as the blood of the whole machine. The quality problems existing in the hydraulic pipeline system of domestic construction machinery are mainly manifested in the oil leakage, oil seepage and cleanliness of the pipeline system, and the product quality is not up to standard. Causes of failure of hydraulic hose assembly: (1) When the hydraulic hose assembly is crimping the fittings the crimping pressure is too large, and the inner rubber layer of the hose is damaged, causing oil leakage. (2) When the hydraulic hose assembly is crimping the fittings, the crimping pressure is not enough, resulting in oil leakage, oil leakage and pulling off. (3) Under the action of repeated pulse pressure, the jacket rebounds and the buckle pressure decreases, resulting in oil leakage, oil leakage and pulling off. (4) The machining accuracy of the joint is not up to standard, resulting in oil leakage and oil leakage at the interface. (5) The use method is incorrect, resulting in reduced service life. During the operation of the hose crimping machine, the operator needs to be familiar with the relevant production processes, be proficient in operating the crimping machine, tools, and labor protection supplies, and can only take up work after they are fully dressed. Before starting the machine, ensure that all fasteners are firm, that each running part and moving surface are free of obstacles, and that safety protection devices are complete. The joint surface of the mold seat and the mold should be kept clean, and there should be no hard objects such as metal chips. First of all, what are the operating steps of the hose crimping machine? 1. Use a ruler to measure the length of the hose sample. Use a caliper to measure the metal joint data and observe the inner diameter of the hose sample. Prepare the required hoses and fittings. Use a pipe cutter to cut the hose to the desired length and clean the inner hole of the hose. 2. Use a peeling machine to peel off the outer rubber of the hose, and then insert the hose into the metal joint sleeve. The outer rubber of the hose must be peeled off. Insert the metal fitting straight into the hose all the way to the bottom. Measure whether the hose is the same length as the hose sample. Machine the hose with a non-taper shrink machine. Adjust the specified data by the positioner according to the hose to be crimped. 3. Start crimping the hose, either using the manual crimping button or using the foot crimping button. Snap the hose into place, then press the mold open button. After crimping, use a caliper to measure the crimping data. The hose can reach the specified withholding data. After the withholding is completed, stop the machine and cut off the power supply. Secondly, what matters should we pay attention to during the operation of the hose crimping machine? 1. Tighten the positioning screws before installing the module. Before starting the machine, lubricating oil should be injected into the inclined surface of the die base. It is strictly forbidden to use the oil cylinder over-travel. If it shakes during pressurization or depressurization, it is strictly prohibited to process it. If the cylinder piston vibrates or the oil pump makes a sharp noise, the gas should be discharged. 2. The pressure regulating valve should be adjusted to the specified pressure and calibrated regularly. It is strictly forbidden to put your hands on the crimping part when the equipment is running. The replacement of the mold should be carried out after the shutdown. When the temperature of the working oil exceeds 45°C, the machine should be stopped for inspection.

What Should Be Paid Attention To When The Hose Crimping Machine Fails

What Should Be Paid Attention To When The Hose Crimping Machine Fails It is absolutely essential that the hose crimping machine encounters failures during use. If you encounter some minor faults, friends who know some mechanical maintenance can probably solve them quickly, but once there are some major faults in the locking machine, it is not so easy to solve. Then it indicates that the locking machine may need an overhaul. So what elements should we pay attention to before overhauling? 1. Technical appraisal before overhaul At present, some overhauls of the crimping machine are mostly repairs to restore its performance. After the machine has been running for a long time, the aging of the main components and assemblies has reached the limit, so all the machines should be carried out. Dismantled, cleaned, inspected and repaired to make it perform to factory standards. Before the overhaul of the crimping machine, a technical appraisal shall be carried out, which shall be presided over by the technical person in charge of the user unit, with the participation of management, maintenance and drivers, and the pressure, flow, temperature and torque of the various parts of the machine before they are disassembled. Review technical files and operation records and other materials, examine the consumption of fuel and lubricants in detail, and make detailed records. Then compare with the relevant overhaul parameters provided by the original manufacturer to determine whether overhaul is required. The main technical conditions that determine whether a crimping hose machinery needs an overhaul are: (1) The engine power performance index drops by more than 20%; the oil consumption exceeds more than 1 times the rated value; the cylinder pressure of the engine does not reach 60% of the specified index when the temperature reaches 45 ℃ or more. (2) The wear of the main parts of the transmission mechanism has reached the limit, and there are phenomena such as yaw, abnormal noise, impact and jitter. (3) After the steering mechanism is worn, the clearance is too large, and the operation fails; the gears and shafts of the transmission are severely worn, and the gear shift is difficult or frequently skips; the braking mechanism is severely worn, and the braking performance decreases or fails, and cannot be adjusted. (4) The main body of the frame is deformed or cracked; the working device is seriously worn and the operation fails; the normal workload cannot be completed, or the operation accuracy cannot meet the requirements; the traveling mechanism is severely worn and cannot work normally. 2. Selection of overhaul method When the hose-crimping machine is overhauled in the factory, each part should be disassembled, measured, inspected and identified, and the wear detection of each part of each assembly, the cylinder liner, crankshaft, etc. of the engine should be carried out to obtain whether basis for replacement. Generally, the moving parts with greater wear and tear need to be replaced; for some parts that are inconvenient to replace, it is advisable to use welding repair, thermal spraying, electric brush plating and chrome plating to restore their original design dimensions. If the quality is not guaranteed, the parts to be replaced should be purchased from the original manufacturer or the designated cooperative manufacturer as required. Maintenance methods are divided into: on-vehicle repair and replacement assembly repair. The car repair method is to remove the parts from the machine in turn during the repair process, clean, test, classify and repair or replace them, and then reassemble them to restore performance. The on-vehicle repair method takes up a long time for downtime for repairs. Replacing the assembly repair method is that in the repair process, in addition to refurbishing the original frame, it is only necessary to remove all the remaining damaged assemblies or accessories and replace them with pre-prepared (or repaired) assemblies or accessories. , and then assembled into a complete machine repair method. This method can greatly reduce the repair time of downtime, which is beneficial to improve the repair work efficiency, reduce the cost and ensure the repair quality. This is also the most popular maintenance method in the American maintenance system, which is of great significance for the user to improve the integrity rate, utilization rate and production efficiency of mechanical equipment.  3. Precautions ⑴ Pay attention to eliminate potential safety hazards. During the overhaul process, attention should be paid to eliminating potential safety hazards, such as: adjusting the brake clearance, replacing the worn clutch friction plates and making the cab seat to be easily adjusted up and down, as well as eliminating some that are likely to cause injuries to drivers and maintenance personnel and machine failures security risks. Strengthen the driver's awareness of labor protection. When carrying out th

Parts Of The Hose Crimping Machine That Need Regular Maintenance

Parts Of The Hose Crimping Machine That Need Regular Maintenance The hose crimping machine produced by the withholding machine manufacturer not only moves smoothly and returns quickly, but also does not cause the phenomenon of spring return, which makes the mold unable to open and crimps. Moreover, the design of the cylinder crimping system is through the front and rear, which is easy to crimp various special-shaped elbows. The hydraulic system consists of a motor, an oil pump, a solenoid valve, a pressure regulating valve and a hydraulic valve to form a double hydraulic oil circuit with forward and backward movement, and a quick oil drain valve oil circuit is added to the double hydraulic oil circuit to achieve a faster return. bit purpose, with adjustable speed, noise and system pressure reduction. When crimping, the crimping speed should not be too fast, which will easily cause damage to the inner rubber and rupture of the steel wire layer, which will cause the hose to be damaged prematurely in use. In actual work, when replacing the high-pressure hose, the length of the hose, the number of steel wire layers, the shape and size of the joint should be reasonable, and the bending degree of the hose should be minimized. Most of the damage to the high-pressure hose is caused by improper production. . Check whether the protective device on the hose crimping machine is in good condition. If it is not installed properly, it is not allowed to drive the intermediate frequency hose pressing machine. It should have good grounding and electrical insulation, and the voltage should be stable. Check the lubricating parts of the hose crimping machine, and add enough oil when there is no oil or no oil. When crimping hoses of different specifications, the indenter of different specifications should be replaced. When oil leakage is found after long-term use, the seals in the oil cylinder and pipe valve system should be replaced in time. The hydraulic oil is 46# Great Wall brand anti-wear hydraulic oil, and the oil temperature is generally controlled at 30℃~35℃. Whether the pipe end is in good condition and the compression degree of the ferrule nut, etc., and at the same time eliminate the external force of the pipe. For flared pipe joints, most of them are caused by excessive flaring, unsatisfactory quality or repeated disassembly, resulting in flaring deformation or cracks, etc. If there is leakage, the front end can be cut off and re-flaring. If the male and female cone top pressure is used for sealing, the leakage is mostly due to the damage of the two cone surfaces. The cone surface can be ground with abrasive sand. In some cases, O-rings are used. For sealing by end face or outer diameter.

The Use Of Hose Crimping Machine In Greenhouse

The Use Of Hose Crimping Machine In Greenhouse The technicians of the crimping machine will explain the application of the crimping machine in the greenhouse today; Greenhouse, also known as greenhouse, can transmit light, keep heat (or heat), and is used to cultivate plants. In the season that is not suitable for plant growth, it can provide growth period and increase yield, and is mostly used for plant cultivation or seedling raising of warm vegetables, flowers, forest trees and so on in low temperature season. So we can eat the vegetables we like in winter, and the greenhouse brings great convenience to people. Greenhouses can be divided into film greenhouses, glass greenhouses, and plastic plate greenhouses according to their materials. Among them, plastic greenhouses are commonly used. The main structure of plastic greenhouses generally uses hot-dip galvanized steel pipes as the main bearing structure, which is factory-produced and installed on site. The firmness of the greenhouse, the steel pipe plays a vital role, because the length and shape of the steel pipe used are different, the steel pipe needs to be inserted. The hose crimping machine uses pressure to crimp a section of the steel pipe to make it smaller, and insert it together with the other section of the steel pipe, so that the greenhouse skeleton structure can be stabilized. Regarding the way to reduce the outer diameter of the steel pipe by crimping, there are two ways, one is through thermal deformation, that is, the steel pipe is placed in a certain temperature environment, and the corresponding tooling is used for processing to make the outer diameter smaller. However, the processing cost of this method is relatively high and the efficiency is low. The other is cold extrusion deformation. The performance of our company's hose crimping machine is stable and reliable. It can crimp the steel pipe and the shape of the crimped steel pipe is neat, easy to install and disassemble, and the steel pipe can be reused.
