Muya Valve Co., Ltd. produced Q941TC...
The volumetric flowmeter installation characteristics and requirements, in order to ensure accurate measurement of the flow meter and reliability of use, it must first ensure that the chamber filled with liquid (dosing chamber) metering the flow, which is one of the principle of measurement accuracy. In the principle of the above requirements, please be sure to follow the installation requirements and procedures. 1. Installation requirements 1.1 Flow meter should be installed before the filter,...
Reason and Repair Method of YHB Vertical Gear Pump Camshaft Breaking Fault 1, the cause of the malfunction YHB vertical gear pump camshaft and pump drive shaft coupling. YHB vertical gear pump cam lift is 10mm, sub-pump center distance of 40mm, the maximum pump speed of 1000 rev / min. Due to high speed working conditions and the installation form of "four-point support" and improper use and maintenance, etc., the circular arc surface of the pump body of the YHB vertical gear pump and the...
Roots vacuum pumps are widely used in paper machine web department, vacuum pressure roller, vacuum pressing, felt dehydration and other paper consumption in the key parts of the process. Roots pump output directly affects the production and quality of paper. When its flow rate decreases, the degree of vacuum decreases, it will cause changes in the moisture of the paper, the formation of consumer sticky roller, embossing and other diseases. Therefore, good Roots pump is very important. Roots...
1, the fuse burned; replace the fuse. 2, relay overload action; overhaul and reset. 3, loose wiring or poor contact; maintenance tightened. 4, the voltage is too low; overhaul. 5, the motor failure; repair or replacement. 6, the body fails; replace the oil, hand rotating body, if unable to rotate, dismantling. 7, relay failure; check the power cord and the contacts. 8, poor contact switch or failure; check the wiring or replacement switch. 9, there is pressure in the oil barrel oil; check the...

Prolong the life of fluorine-lined valve method 1, lined with fluorine valve storage, it is best placed in a dry room, to avoid open air sun and rain, to avoid stacking in the vicinity of heat to prevent fluorine plastic aging and deformation. Both sides of the plastic flange sealing surface should be protective cover, sealing surface shall not be scratched, stacking should be avoided at both ends of the flange sealing surface pressure. 2, the storage and storage of the valve should be...
(1) sealing friction deputy face serious wear and tear. Due to the viscosity of residual oil, poor fluidity, and the residue medium contains granular and powdered cokes, there is inevitably coke around the friction pair, which is quite damaging to the friction pair. Once the coking material enters the sealing face, Po Taibang will quickly scratch the sealing face due to friction and vice-versa, causing scratches. As the polymer and foreign particles continuously enter the friction face, the...
The silencer check valve is an automatic valve. Its function is to prevent the medium in the pipeline from flowing backwards. It is mainly used for the pipe that the medium is unidirectional and only allows the medium to flow in one direction to prevent accidents. Silent check valve maintenance and care are as follows: 1) When opening and closing storage and transportation should be in the shutdown device, and should do the following: ① silencer check valve flap should be fixed in the open...
According to pump selection principle and selection of basic conditions, the specific operation is as follows: 1. According to the layout of equipment, topography, water level conditions and operating conditions, the choice of horizontal, vertical and other types (pipeline type, submersible type, submerged type, non-clogging type, self-priming type, gear type, etc.) Pump. 2, according to the nature of the liquid medium to determine the water pump, hot water pump or pump, chemical pump or...
Fatigue wear, erosion wear, abrasive wear, adsorption wear, these four wear centrifugal fan is the use of the main wear factors. In summary, the fatigue wear is due to surface fatigue stress (or temperature or impact) caused by surface cracks or scale shedding caused by fatigue wear. From the damaged impeller point of view, various forms of impeller wear situation and parts vary. However, the main form of wear more than the above and are all local wear and tear. Worn parts mainly in the blade...
BRY air-cooled centrifugal heat transfer oil pump maintenance should pay attention to ten aspects .1. After using the vacuum oven, be sure to do a clean job, clean the vacuum oven glass. 2. Wipe the exterior anti-rust oil. 3. Eliminate the governor cavity, spray smooth BRY air-cooled centrifugal oil heat pump cavity anti-rust oil, to participate in the rules of the trademark of smooth oil. 4. The anti-rust oil in the fuel pipeline should also be removed before use. Connect the fuel to the...
1, energy-saving inverter From the fluid mechanics, P (power) = Q (flow) ╳ H (pressure), the flow Q and the rotational speed N is proportional to the first power, pressure H and the rotational speed of the square is proportional to N, the power P and the rotational speed of the cube is proportional to N , If the efficiency of the pump is constant, when the demand for adjusting the flow rate decreases, the rotational speed N can be decreased proportionally, while the axial output power P has a...
1. The conductor in the magnetic field, through the current, the conductor will be subjected to the thrust of the magnetic field, the three directions perpendicular to each other, the size of the thrust F = I × B × L. Conducted boiler feed pump without any rotating parts, to solve the mechanical pump wear problems, the formation of maintenance-free welder. However, due to the liquid metal contact with the large current electrode to the liquid metal conduction current process, due to the oxide...
Vacuum pump oil seal installation method First, the oil seal in the shell hole installation method Oil seal assembly shell surface roughness, surface quality is particularly important. In the assembly should be checked whether the debris on the inner wall, scratches, dust and sand casting, etc., should be used special tooling will be a smooth seal into the shell seat seat hole. Second, the oil seal installed in the shaft diameter of the oil seal is usually smaller than the shaft diameter, the...
According to the solid transport theory, tapering and longitudinal grooves are machined on the barrel wall of the charging section and intensive cooling is performed, which greatly improves the solid transport power. If the structure of the cylinder used in this way, when planning the screw must be in the melting section and the homogenization section to adopt the appropriate method so that the melting rate, homogenization and feeding section can be consistent with the delivery. Screw pump...
First, the 300X slow closing check valve features: 300X slow closing check valve is a hydraulic control system composed of the main valve, check valve, needle valve, ball valve, microfilter, pressure gauge together. By hydraulic automatic operation, can cause the main valve to get the best Kai, closing speed. Doing so can avoid the occurrence of water hammer hammer, so you can achieve the effect of slow closing silencer. 300X slow closing check valve by hydraulic self-control, without other...
