Grading Method and Grading Criterion 1. The members of the bid evaluation team made a comprehensive score on the quotations, company performance, after-sales service, and technical indicators of the products submitted by the suppliers. The bidder with the highest comprehensive score among the bidders of this project was the successful bidder. Second, the scoring standard (percentage system) 1, quoted score (30 points) 1.1 to meet the tender requirements of all documents, the average bid price is the benchmark bid evaluation. 1.2 Quotation score = bid evaluation base price / bid price * 30 2. Performance score (20 points) A maximum of 2 points will be awarded for each contract for a car wash project in the past two years with a value of 5 million yuan or more. 20 points. A copy of the contract is attached to the negotiation response document, and the original contract is verified on the day of negotiation. If the original contract cannot be provided or is inconsistent with the original, no score will be awarded. 3, technical performance (26 points) 3.1 Technical parameters to fully meet the requirements of the tender documents, have a basic score of 24 points; 3.2 technical parameters are not met, each one is not satisfied, on the basis of the basic 24 points deducted 2 points, After deduction. 3.3 The bidder’s products have independent innovation, the technology is at the leading domestic level and owns independent intellectual property rights, and each certification provides 0.5 points and a maximum of 2 points. The non-provider shall have a score of 0; (The above independent innovation bidders shall provide certification materials recognized by relevant national authorities, including patent certificates, national new product certificates, and scientific research achievement appraisal reports, etc. Documents, the original for future reference.) 4, after-sales service (6 points) 4.1 Warranty period: one year or 2000 hours, return visits every six months; free maintenance during the warranty period, warranty period only charge the cost of spare parts and equipment, and responsible for life After-sales service; (1 point) 4.2 Technical training: to the site for the use of contract products, some maintenance, common troubleshooting, product principles, system theory training, and provide the appropriate technical information, to provide users with the corresponding Chinese operating instructions, Chinese Operational brief description; 4.3 Service time guarantee: The factory is required to have offices in neighboring cities within 100 kilometers of Kaifeng City.
The safe operation rules of the sweeper The sweeper sprays high pressure water to perform the cleaning operation. Therefore, if the use and operation methods are incorrect, it will cause human accidents and should be handled with caution.
(1) There are many sediments and they are not cleaned at one time. The cleaning vehicle can be repeated.
1. During the cleaning operation, if the pressure is stable, the pressure gauge switch may be closed to protect the pressure gauge. However, if there is any change in the working conditions, the pressure gauge switch should be turned on immediately to monitor the pressure change.
2. If the water level is at a dangerous water level, stop the operation immediately and add water;
(2) Scrubber back cleaning
1. One manipulator to protect the high pressure hose
2. The roll tube handle is placed in the "received" position, and the reeling tube is rotated counterclockwise to wind the high pressure capillary tube.
3. The speed control knob depends on the amount of sludge, properly adjust the speed of the tube;
4. Open the needle valve;
5. Increase the hand throttle to clean the water pump at 1000-1200 rpm.
6. When the nozzle approaches the entrance, turn the hand throttle so that the water pump rotates at a relatively low speed until it finishes cleaning the sewer.
(3) Parking position when washing vehicle sewer cleaning operations
1. The cleaning truck should stop at the sinking shaft of the sewer line. If the parking position is not suitable, it will not only reduce the operating efficiency, but also shorten the service life of the hose.
2. The cleaning truck should stop at the downstream wellhead of a section of the sewer to be cleaned, and the car should be parked downstream; a. When the pipeline is completely blocked and there is a lot of sediment, cleaning operations should be started from the most downstream caisson in this section; b. The cleaning operation can be started from the upstream caisson;
(4) Check the following before cleaning the water pump driving operation of the washing vehicle: Operation cabinet
1. Hand throttle in "small" position;
2. High-pressure three-way valve set to "return to water" position; Hydraulic system 1. Whether the tank is filled with enough oil; 2. The two stop valves under the tank are opened; Water system 1. The tank is filled with clean water; Is the valve open; 3. Is there a blockage on the filter?
4. Check the amount of oil in the pump's crankcase; Point: Roller handle is placed in “stop†position; speed control knob is placed in “slow†position; pressure gauge switch is set in “closed†position; wash pipe is placed in “closed†position. Position; after confirming that all the above items are in the correct position, start the engine and move the water pump on the transfer box after the clutch lever, and the water pump can run at low speed;
(5) General considerations for cleaning vehicles
As one of the leading die casting manufacturers with over 10 years of experience, Zheke Mould Company has been offering superior die casting parts for Automobile manufacturing and other indudustries. With our professional technicians and cutting-edge die casting process, every piece of our parts comes out with reliable quality and cost effectiveness.
Application of Aluminum Die Cast in Auto Parts
Numerous parts can be cast effectively using aluminum die cast like Valve covers, Wheels, Transmission housings, Engine block, Wheel spacer, Carburetors, Impellers and Fan clutch, Alternator housing etc.
Automobile equipment are generally made of aluminum die castings. They offer the following benefits:
• Light weight, just one third of the weight of steel parts.
• Auto parts with aluminum can be cast net shape.
• Good production run with die cast auto parts produced in hundreds to thousands per day.
• Good thermal properties.
• Cheaper in cost.
