How to choose the connection mode of hydraulic valve? 01
The solution of high oil temperature in hydraulic power station
Hydraulic oil is the working medium of the hydraulic transmission system, generally working in the range of 35-60℃ is more suitable, in the hydraulic system is working, pressure loss, solvent loss and mechanical loss will be converted into heat energy and make the oil temperature rise, the change of oil temperature will cause the viscosity change of the oil, resulting in the mechanical system movement speed instability. The system oil temperature is too h
Elimination method of high oil temperature in hydraulic power station
1 ► Set the pressure too high Adjust the pressure properly 2 ► The components of the relief valve, unloading valve, pressure relay and other unloading circuit are not working properly 3 ► The element setting value of the unloading circuit is not appropriate, and the unloading pressure is re-set in a short time to extend the unloading time 4 ► Large leakage of valve, short unloading time repair large lea
Characteristics and application of mobile hydraulic station
The mobile hydraulic station is a hydraulic source device composed of a fuel tank, a direction valve, a relief valve, a hydraulic pump, a driving motor, etc., or a hydraulic device including a control valve. The mobile hydraulic station is convenient to move, suitable for field operation, and the power supply is inconvenient, so the mobile hydraulic station has large power. Mobile hydraulic station features:
Excavator important button switch introduction
First, hydraulic safety lock switch When you open the door of the excavator, you can see it. The "safety lock", as the name suggests, is designed with the safety of the driver in mind. Since the action of the excavator is driven by hydraulic pressure, the safety lock can control the hydraulic pressure transmission in time. When the excavator is started, the driver sits on the seat and turns the hydraulic safety lock to the unlocked state, at which time the operation handle or walking pedal excavator will have the corresp
Hydraulic power station maintenance points to pay attention to
As an important part of hydraulic mechanical equipment, hydraulic power station needs regular maintenance or maintenance. If you do not pay attention to the daily maintenance operation during use, it will greatly reduce its service life and efficiency, affecting the stability of the overall equipment, if the hydraulic station is unstable, it will cause the overall equipment to increase the cost and loss during cutting processing, resulting in reduced operating efficiency, or reduce the service life of the equipment!
How to improve the efficiency of hydraulic station
Hydraulic station in the working process can not avoid the loss of power, how to improve the power of the system? First of all, the pressure limiting variable pump must be selected. When the system pressure is reduced, the flow rate is relatively large, which can meet the rapid stroke of the actuator. When the system pressure is increased, the flow rate becomes smaller, which can meet the stroke of the actuator. The second is
The processing technology of the main components of hydraulic valve
The manufacture of hydraulic valves, first of all, according to the design pattern, process documents and technical requirements carefully processed spore, valve body and other parts, followed by the selection of electrical, mechanical converters and other accessories; Finally, carefully assembled, through the test according to relevant standards to obtain high-quality products. Today, Xiaobian takes you to understand the processing technology of the main components of the hydraulic valve (valve body, valve core, valve sleeve).
Summary of experience in commissioning and acceptance of hydraulic system
After the hydraulic equipment installation and circulation flushing are qualified, it is necessary to adjust the hydraulic system for test run, so that it can make necessary adjustments according to the actual production process requirements under the premise of meeting the technical parameters, so as to achieve normal operation under heavy load. 1.1 Preparation before commissioning of hydraulic system &
Steps to be taken when using the hydraulic system for the first time
When the hydraulic system is used for the first time, some necessary initialization operations are required. This article will tell you the steps of using the hydraulic system for the first time, you can refer to this article when operating other hydraulic systems, the general steps are the same. However, different hydraulic systems in the details of the solenoid valve, pressure value operation part may have some differences, please refer to Ha as appropriate.
Hydraulic power station daily maintenance tips
In daily use, many failures of hydraulic power stations are caused by inadequate maintenance, so it is extremely important to do its maintenance and maintenance. First, the tubing joint should be cleaned in time to prevent leakage Clean the hydraulic power station at the end of each use. The joint connected to the hydraulic oil pipe must be cleaned, otherwise it is easy to leak the hydraulic oil.
The first condition for the normal operation of the hydraulic system is that the inside of the system must be clean. Hydraulic system in the manufacturing and assembly and use of the process is inevitable to be polluted, even new oil, sometimes contain some unexpected pollutants, therefore, measures must be taken as soon as possible to filter out the pollutants, otherwise it is possible to malfunction after the equipment is put into operation, and early failures are often very serious. Some components such as pumps, valves, and motors can be fatally damaged.
1. Introduction Fundamentally, hydraulic pressure is the transfer of force and energy through the static pressure of fluids. In the market, hydraulic systems are parallel with mechanical systems, electrical systems and pneumatic systems, and there is some competition. Hydraulic systems have many comparative advantages as well as some disadvantages. Advantages of hydraulic system: - Can transmit large forces in a small space;
In the hydraulic system, the hydraulic tank is mainly to store oil to meet the flow required by the normal operation of the hydraulic system; In addition, it also plays a role in heat dissipation, separation of bubbles in the oil, precipitation impurities and so on. These functions are achieved by auxiliary components in the tank, such as air filters, oil filters, coolers, etc. As a hydraulic system oil storage device, in the design of the tank, in addition to calculating its circulation volume, it is necessary to fully consider the complexity of the equipment con
Problems and improvement measures of suction filter for hydraulic oil tank of excavator
The main function of the hydraulic tank of the excavator is to store the hydraulic oil of the hydraulic system, distribute the heat in the hydraulic oil, and separate the gas and sediment in the hydraulic oil. The hydraulic oil tank is equipped with a partition to prevent excessive fluctuation of hydraulic oil, increase the circulation distance of hydraulic oil, so that the hydraulic oil has enough time to separate bubbles, precipitate impurities, and dissipate heat. The hydraulic oil tank is equipped with an oil suction filter and an oil return filter, which are
