Failure analysis of the high pressure system of the hose crimping machine

Today, the editor of Dalian Barnett Flex Hydraulics Co.,Ltd. will introduce to you: 1. The machine does not work after booting First, check whether the motor direction is forward or reverse. Secondly, check whether the handle of the flow valve is loose. Solution: Adjust the rotation of the motor to make it consistent with the rotation of the oil pump. 2. The system is noisy Check the plunger pump, check whether the oil filter is blocked, and whether the hydraulic oil meets the requirements Solution: in the oil filter or hydraulic oil 3. No pressure in the cylinder Check the plunger pump (gear pump), check the safety valve, check the oil cylinder. Solution: Adjust or replace the pressure of the safety valve.

The performance of the hydraulic oil of the hose crimping machine

Hydraulic oil is the blood of the hose crimping machine equipment, which plays the role of transferring and converting energy. The correct selection of hydraulic oil is closely related to the efficiency and service life of the equipment. Its performance is mainly shown in the following points. Today we will analyze a bit: 　　 1. Proper viscosity, good viscosity-temperature characteristics Viscosity is the first factor to consider when selecting hydraulic oil. Under the same working pressure, if the viscosity is too high, the movement resistance of hydraulic components will increase, and the pipeline pressure drop and power loss will increase; if the viscosity is too low, it will increase the volume loss of the oil drum. The leakage in the assembly increases, and the oil film of the sliding parts becomes thinner, the supporting capacity is reduced, and there is atomization, which overflows from the exhaust port. 　　2, good lubricity (wear resistance) 　　 There are a large number of moving parts in the hydraulic system that need to be lubricated to prevent the wear of the relative moving surface, especially the hydraulic equipment with higher pressure, which requires much higher anti-wear properties of the hydraulic oil. 　　3, good oxidation resistance The hydraulic oil is also oxidized during use. The acidic substances generated after the hydraulic oil is oxidized will increase the corrosiveness of metals. The sludge deposits produced will block the filter and small gaps, making the equipment work abnormally, so it is required to have good The antioxidant properties. 　　4, good rust and corrosion resistance The hydraulic oil will inevitably come into contact with moisture and air and the acidic substances generated after oxidation will affect the corrosion of the metal valve core and make the hydraulic crimping machine equipment unable to work normally. The hydraulic crimping machine of Kangmai company depends on the frequency of use. It is recommended to thoroughly replace the new and old oil in 3-5 years.

The working principle of the hose crimping machine and its installation and debugging process

The hose crimping machine is also called a hose crimping machine. The hose crimping machine is composed of a withholding mechanism, a motor, a control valve, a gear and an oil tank. High-pressure hose assembly is widely used in oil fields, coal mines, agricultural machinery and other industries. It is an ideal equipment for the industry. The tube crimping mechanism is the working mechanism of the tube crimping machine. Want to know how to install and debug the tube crimping machine? Let me introduce it next. 1. For transportation, it is better to use a forklift. 2. The installation of the machine should be stabilized on a fixed foundation and grounding should be done. 3. Open the rear side cover of the fuel tank and add about 54 liters of hydraulic oil to the fuel tank. 4. Connect the power, connect the power cord to the power supply on the machine, and adjust the relative direction.

BNTP32CNC new type hose crimping machine

The 100 CNC hose crimping machine is a newly launched equipment of our company. In order to better meet the needs of customers, it has increased the passing capacity of the hose and added a lubricating oil cup to speed up the crimping speed. The machine is beautiful in appearance, compact in structure and simple in operation. The oil cylinder will automatically return when the three-phase and single-phase voltages are in place. It can be operated manually and automatically, and it runs smoothly and reliably. The failure rate is low, and the mold and the mold base are axial Sliding and dovetail connection satisfy the free crimping of the double elbow hose.   Widely used in the market, such as: suitable for the production of high-pressure hose assemblies in construction machinery, coal mine hydraulic machinery, oil fields, auto parts and other industries. The universal hose crimping machine tightly presses the metal joints with the high-pressure hose through hydraulic machinery and corresponding abrasive tools to make high-pressure hose and fluid connectors, referred to as high-pressure hose assembly. The principle of the pipe crimping machine is that the oil pump is driven by the motor to output hydraulic oil and push the plunger in the withholding cylinder to move forward, so that the plunger and the two inner cone sleeves on the front cylinder cover push the radial direction of the mold base with symmetrical cones. Shrink, realize the module to withhold the hose. When the shrinkage reaches the scale setting value, the crimping stops automatically. After the electromagnetic reversing valve changes the direction, the hydraulic oil enters the two mold openings, pushing the crimping plunger to move in the opposite direction, and the mold seat drives the module to recover under the action of the spring. The hydraulic system of the pipe crimping machine is an important part of the equipment. It consists of hydraulic pump, reversing valve, safety valve and so on. In order to save money, some low-priced locking machine manufacturers often do not set up various inspection positions, such as purchase inspection, assembly process inspection, warehousing inspection, and factory inspection, resulting in unstable product quality and chaotic market prices.
