The hydraulic pump is a hydraulic component commonly used in hydraulic systems. How to solve the problem when the hydraulic pump is abnormal? Dalan Hydraulics tells you the method. The hydraulic pump is a hydraulic component commonly used in hydraulic systems. How to solve the problem when the hydraulic pump is abnormal? Dalan Hydraulics tells you the method. Fault 1: There is air in the hydraulic pump This kind of failure is usually caused by the installation of a new pump. When opening a new...
When there is a problem with the hydraulic oil pump motor bearing, we thought it would be good to replace the bearing. However, if you think it is so simple to deal with, then you are very wrong. Today, the editor of Dalan Motor will take you to understand the six symptoms of bearing damage and take corresponding measures. 1. Bearing surface peeling When the bearing rotates under load, the raceway surfaces or rolling body surfaces of the inner and outer rings of the bearing show scaly peeling...
What are the brands of high temperature pumps , and which high temperature pump brands are good? The over-current components of the high-temperature pump are made of stainless steel and are widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, national defense and other departments. They are ideal equipment for conveying flammable, explosive, toxic and valuable liquids. The best choice for leaking, pollution-free civilized workshops. So...
What are the classifications of hydraulic pump seals? And see how Dalan Hydraulics analyzes! What are the classifications of hydraulic pump seals? And see how Dalan Hydraulics analyzes! Seals are mainly divided into the following major categories: 1. Balanced and unbalanced seals 1 The balance of the mechanical seal has a great influence on the sealing pressure of the contact surface. This sealing pressure depends on the effective cross section of the seal itself and the pressure inside the...
The construction of bridges and tunnels is the difficulty and focus of railway construction. Tunnels must be digged to a certain depth in the current dry season to create conditions for the construction of the rainy season before the arrival of the rainy season. Taian Concrete Pump Co., Ltd. has been cultivating in the African market for many years, establishing a sound channel network, improving product competition strategies, strengthening the service parts support system, and improving the...
From the start of the first day of the Sany Express live broadcast of the stunning first show, the goddess online to send Mercedes-Benz, to the recent network broadcast volume of more than 10 million, million yuan to send non-stop # Discovery Sanyi # image contest, welfare wave after wave, The vast majority of engineers in the engineering community are calling me to help me, I want to! ! ! Last night, Xiao Bian received mysterious news - Sany also had to send (in) Fu (things) profit (love),...
The noise of the hydraulic pump is mainly caused by the following three reasons. Dalan Hydraulics will analyze it with you. The noise of the hydraulic pump is mainly caused by the following three reasons. Dalan Hydraulics will analyze it with you. 1. Suction is one of the main causes of excessive noise of hydraulic pumps. When air is mixed into the oil, it is easy to form cavitation in its high pressure zone and propagate in the form of pressure waves, causing oil to oscillate, causing...
In the actual application process of the special motor for hydraulic oil pump, many factors will cause failure. Today, the editor of Dalan Motor listed five common causes. Let's take a look at the five types together. 1. Overheating Overheating is the main culprit of motor failure, which is a common problem we talk about. So why does the editor still come up with it today? In fact, the other four reasons listed in this article are part of the list because they generate heat. Theoretically,...
Working principle of hydraulic pump station (system) The hydraulic station is the power source of the hydraulic transmission device. It supplies oil according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines where the driving device and the hydraulic station are separated. The hydraulic station and the driving device (cylinder or oil motor) are used When the oil pipes are connected, the hydraulic system can realize various prescribed...
Information details Hydraulic maintenance: the difference between hydraulic pump and hydraulic motor Time: 2014-08-18 Source: http:// The hydraulic pump converts mechanical energy (such as the rotation of the motor) into pressure energy, and the hydraulic motor that transmits the pressure oil needs to perform work everywhere. The hydraulic motor converts the pressure energy into mechanical energy, and the pressure oil pushes the rotation of the blade in the hydraulic motor, thereby driving The...
When there is a problem with the bearing of the hydraulic oil pump motor, we thought it would be better to replace the bearing. However, if you think that such a simple treatment is enough, then you are quite wrong. Today, the editor of Dalan Motor will take you to understand the 6 major symptoms of bearing damage and take corresponding measures. 1. Peeling off the bearing surface When the bearing rotates under load, the raceway surface or rolling body surface of the inner ring and outer ring...
An electric hydraulic pump is a hydraulic component that provides pressurized liquid and is also a type of pump. Its function is to convert the mechanical energy of an electric motor or internal combustion engine into the pressure energy of a liquid. He is also an energy device that provides hydraulic oil to hydraulic transmission systems. If you want to understand the electric hydraulic pump, you should first understand the working principle of the electric hydraulic pump. Working...
First, what is the phenomenon of hydraulic pump trapping oil? The closed working volume of the hydraulic pump forms a closed volume during the transfer to the pressure chamber after the oil is filled. If the size of the closed volume changes, when the dead volume changes from large to small, the oil in it is squeezed, the pressure rises sharply, the bearing is subjected to periodic pressure shock, and the oil is heated; When the volume is changed from small to large, vacuum is generated due to...
Turn-to-turn faults are an unavoidable problem in the manufacturing process of hydraulic oil pump motors. Large enterprises are equipped with turn-to-turn testers, but small businesses and repair companies do not necessarily have this equipment. Therefore, the simple frequency modulation test method is very effective. of. Please check with the editor of Dalan Motor for details. 1. Inter-turn fault appearance After an inter-turn short-circuit fault occurs in the stator windings of the motor, the...
The hydraulic puller is one of the hydraulic tools, and its principle is that the hydraulic starting rod moves directly forward, so the pushing rod itself does not rotate. The hook jaw seat can also be adjusted forward and backward directly with the thread. During operation, only a small swing of the handle is required to swing forward and backward, the hydraulic start lever moves forward, the hook jaw moves backward relatively, and the pulled object is pulled out. There are many hydraulic...
Hydraulic test bench hydraulic system hydraulic pump comprehensive mode and improvement at a glance. Hydraulic Yingcai network hydraulic Ligong share power steering hydraulic pump in the test process, the main parameters need to be measured in addition to the general hydraulic pump temperature, flow, pressure, speed, torque In addition to the characteristic parameters, due to the special layout and use requirements of the power steering hydraulic pump, it has its specific performance....
Manual hydraulic pump equipment in industrial production can be developed with the size of their products, the work is the most concerned about the issue in the manual hydraulic pump oil storage tank in place before the start of operation to him Check and check at 1 CM inlet to ensure that the reservoir is not full, lest hydraulic oil overflow from the inlet. If necessary, add hydraulic oil as excessive hydraulic oil may occur. How to adjust the pressure of manual hydraulic pump How to adjust...
The hydraulic wrench is an important tool for the installation and disassembly of large-size bolts. There are two types of hydraulic torque wrenches: driven hydraulic torque wrenches and hollow hydraulic wrenches. Driven hydraulic torque wrenches are used with standard sleeves and belong to general-purpose hydraulic wrenches. The thickness of the hollow hydraulic wrench is relatively thin, so it is suitable for use in places with relatively small space. Hydraulic wrenches are so widely used, do...
